Just 16% Of Indian Population Has Access To Free Or Partially-Free Health Care?

Is health care currently a low priority area for the Government of India? Probably yes, and thus it is worth trying to fathom it out.

Besides planned frugal spending on overall public health in 2015-16, even as compared to the past trend, two other health related budgetary decisions of the Government are indeed baffling, at the very least.

As many of you, I too know that the incumbent Government in its first full-year budget of 2015-16 has sharply reduced the budgetary allocation on many important health related other projects, such as:

- Union budget allocation for the National Rural Drinking Water Program (NRDWP) that aims at providing safe drinking water to 20,000 villages and hamlets across India, has been drastically reduced this year. Curiously, this decision has been taken at a time, when India loses 200 million person days and Rs 36,600 crore every year due to water-related diseases.

- The Integrated Child Development Services (ICDS) scheme, which provides food, preschool education, and primary health care to children under 6 years of age and their mothers, has also been hit by a 54.19 percent budget cut this year. This decision too of cutting public expenditure on food, nutrition and health care for children to more than half, defies any logic, especially when 40 percent of growth stunted children in the world are reportedly from India, exceeding the number of even sub-Saharan Africa.

I hasten to add that the Union budget 2015-16 has indicated, as the states’ share in the net proceeds of the union tax revenues has increased, as per recommendations of the 14th Finance Commission, these central Government programs will now be run with a changed funding pattern between the Union and states. However, according to financial experts in these areas, regardless of devolution, the total money available to run these critical projects is sharply decreasing.

That said, on the other pages of the same Union Budget, public funding in the current fiscal year for bridges and roads has more than doubled. The budgetary allocation for these two areas now stands more than even education.

I deliberated on similar subject of access to health care in my blog of March 16, 2015, titled, “With Frugal Public Resource Allocation Quo Vadis Healthcare in India?

Health care sector is important for job creation too:

According to the World Health Organization (WHO), health care sector is one of the largest job creators, not just in India, but globally. Thus, Indian health care industry being one of the fastest growing industrial turf in the country with a reasonable base, deserves a sharper focus of the Government.

Additionally, the socio-economic benefits that this sector provides in creating a sustainable, healthy and highly productive work force, has been well documented and can’t just be wished away, in any case.

The neglect is intriguing:

Currently, total healthcare spend of India is no more than 4.2 percent of the GDP with public spending being just 1.2 percent of it. Other BRICS nations are way ahead of India, in this area too. To set a direction on country’s public healthcare spend, breaking the jinx of a long period of time, the draft National Health Policy 2015 of the Government aimed at initial increase in health expenditure to 2 percent of the GDP.

As a result of the legacy of neglect over a long period of time, which continues albeit more blatantly even today, only 16 percent of the Indian population declares today that they have access to free or partially-free health care. I shall dwell on this area subsequently in this article.

Keeping these in perspective, it was intriguing, when the union budgetary allocation for health care in 2015-16 was kept at Rs. 297 billion or U$4.81 billion for its main health department, almost the same outlay as in the previous budget.

When compared against public fund allocations, such as, US$ 93 billion for highway projects or US$ 7.53 billion for 100 smart cities in the country, one will get a realistic perspective of this meager health budget allocation, in terms of effectively addressing the health care needs of around 1.25 billion people of India. Over 70 percent of this population live in the hinterland.

Agreed that the Government focus on these ‘infrastructure projects’ are not unimportant by any means. Nevertheless, the above comparison only highlights how much priority the Government assigns to the health care sector of India and for the health of its citizens. This issue assumes even greater significance in combating several challenging health situations, such as, ongoing fight against increasing incidence of life-long chronic ailments and deadly life-threatening diseases like, cancer, fueling already high rate of morbidity and mortality in the high country.

A quick glimpse on a few outcomes of neglect:

The Working Paper No. 1184 dated January 8, 2015, titled “Improving Health Outcomes And Health Care In India” of the Organization for Economic Co-operation and Development (OECD), highlights some interesting points, as follows:

  • Chronic diseases are the biggest causes of death and disability accounting for 50 percent of deaths, with cardiovascular diseases and diabetes, respiratory conditions and cancers figuring most prominently.
  • Preventive interventions such as improving access to a clean water supply, reducing the spread of HIV/AIDS through better sexual education, and vaccination campaigns for other diseases will each deliver more significant returns in life years.
  • Vaccination rates for diphtheria, tetanus and pertussis, for measles and for hepatitis B are all much lower than in OECD and peer countries.
  • Minimal access to free or partially-free health care.

It is an irony that ‘life expectancy’ in India still remains well below the countries at a similar level of development.

Abysmal overall hygienic conditions:

The OECD survey brings to the fore  abysmal hygienic conditions still prevailing in India. It can only be improved through active intervention of the Government with necessary budgetary allocations, sans photo ops for some celebrities and most politicians. Sincere support and participation of the civil society and intelligentsia, in general, are also equally important.

The paper underscores, among others, the following extremely unhygienic conditions still prevailing both in urban and rural India:

  • Most households in rural India do not defecate in a toilet or latrine, which leads to infant and child diseases (such as diarrhea) and can account for much of the variation in average child height. Even today the sight of poor children defecating openly in the streets, that too in a city like Mumbai, is also not very uncommon.
  • The burning of solid fuels in particular (undertaken by more than 80 percent of the population in cooking) is a major risk factor behind ischemic heart disease, lower-respiratory tract infections and chronic obstructive pulmonary diseases and could also increase cataracts and stroke.
  • Exposure to air pollution is a significant problem.
  • Many of the poor continue to smoke heavily.
  • 11 of the lowest income quintile did not undertake sufficient physical activity, compared with 16 percent in the highest income quintile.

India provides minimal access to free or partially-free health care:

As I mentioned above, India provides minimal access to free or partially-free healthcare to its citizens, as compared to all the BRICS nations, many other countries in South East Asia and even in Africa.

The above OECD paper states that with poor health intertwined with poverty, the greatest gains lie with policies that address the social conditions which enable combating communicable and non-communicable diseases.

Among BRICS countries, India provides least access to ‘Free or Partially-Free Health Care’ Services to its general population. This is despite being the largest democracy in the world, which is now striving hard to emerge as an economic and military superpowers.

The following study shows that only 16 percent of the Indian population declares having access to free or partially-free health care from the government:

BRICS Countries % surveyed said ‘Yes’ to the question: “Does your household have access to free or partially free health care from the State”
India 16
Brazil 24
China 73
Russia 96
South Africa 62

Source: Credit Suisse Research Institute, Emerging Consumer Survey Databook 2014.

As the OECD paper states, in this study approximately 1500 respondents were surveyed in each country, with India and China both having larger sample size of 2500. The male-to-female split between respondents was roughly 50:50 in all cases with rural-to-urban split varying by country.

Poor satisfaction level with existing health care services:

This is very important; as public facilities are the predominant source of qualified health professionals in rural areas where much of the Indian poor reside. In addition, significant population growth is occurring in urban slums, where urban public health care facilities are struggling to provide basic services. In a situation like this, slum dwellers face challenging economic barriers to accessing expensive private health care services (MoHFW, 2012).

The OECD survey indicates that 41 percent of those in rural areas and 45 percent in urban areas were not satisfied with treatment by their doctors or facility.

The reason attributed to this dissatisfaction are as follows:

  • Distance was cited by 21 percent of people in rural areas and 14 percent in urban areas.
  • Public health care centers remain closed more than half the time and lack basic medical supplies, such as stethoscopes and blood pressure scales.
  • Non-availability of required services was cited by 30 percent of people in rural areas and 26 percent in urban areas.

This is quite credible, as according to the Government’s own estimates:

- 10 percent of primary health care centers are without a doctor

- 37 percent are without a laboratory technician

- 25 percent without a pharmacist (MoHFW, 2012)

The above picture is quite consistent with large scale surveys in poor communities of India, by OECD.

Health care business for up market is booming:

Growing inequitable distribution of healthcare products and services is now wide open and blatant, more than ever before. There is no signal yet that the Government would soon consider health care sector as its one of the key focus areas, along with education, just as infrastructure, such as, building roads, highways, e-highways, flyovers, bridges and smart cities.

For up-market patients, the private sector is creating world class facilities in India. We can see today a good number of ‘five-star’ hospitals, with more number of newer ones coming up offering jaw-dropping facilities, quite akin to, may be even surpassing what are being offered for patients’ luxurious comfort in the developed world. Although these facilities cost a fortune, one would usually need to be in a queue to get admitted there for any medical or surgical treatment.

Most of these hospitals are now in high demand for ‘medical tourism’. According to available reports India currently caters to health care needs of over 200,000 foreign patients. ‘Medical tourism’ business reportedly fetched around US$ 2 billion to India in 2012.

On the flip side of it, as we all read in the recent media reports, some of these hospitals in Delhi refused admission even to seriously ill dengue patients, as they can’t afford such facilities. A few of these patients ultimately succumbed to the disease and the parents of one such poor child, who died without any hospital treatment in that process, committed suicide unable to withstand the irreparable and tragic loss.

Giving ‘Infrastructure Status’ to health care sector:

When creating basic infrastructure is the priority area of the present Government for financial resource allocation, why not give ‘infrastructure status’ to the health care sector now? This is not just for the heck of it, but purely based on merit and earlier detail evaluation by a Government Committee of experts.

To address the critical health care needs for the vast Indian population with appropriate infrastructure, quality products, services and manpower, providing ‘infrastructure status’ to the health care sector could facilitate the whole process. Additionally, it can transform the Indian healthcare sector as one of the biggest job-generating industry too.

This has been a key demand of the industry until recently, though not so much being talked about it today. A few years back, the previous Government was reportedly mulling to assign full fledged infrastructure status to the healthcare sector, as it merits inclusion in the category of ‘infrastructure’, satisfying all the nine criteria set by the erstwhile Rangarajan Committee.

I find in my archive, the Confederation of Indian Industry (CII) also demanded ‘infrastructure status’ for the health care sector in its pre-union budget memorandum for 2010-11. In that proposal CII had estimated that health care industry in India requires an investment of around US$80 billion, whereas in the current fiscal year the public expenditure on health still languishes at U$4.81 billion.

This specific issue seems to have taken a back seat today, for reasons not known to me. However, it is interesting to note that not just the Government apathy, no such demand is being made today by the large multi-industry trade associations of India, as vociferously as we witness, for example, in the case of ‘The Goods and Service Tax (GST) Bill’.

Health care debate is not to the fore today:

Critical health care issues of the country don’t seem to be in the fore front today for comprehensive debates even for the Indian main stream media, to influence the government.

We have been experiencing for quite while that Indian media, including social media, in general, usually goes ballistic 24×7 mostly with selective sensational topics. These may include, among others…glitzy events on Government’s high profile advocacy initiatives to attract more Foreign Direct Investment (FDI) from large overseas companies…Or back home some unfortunate and tragic Dengue fever related deaths due to negligence just in Delhi, though the same and equally grave incidences taking place in the other states of India, are hardly getting any coverage…Or on some high profile alleged murder pot-boilers announcing media verdict conclusively, even before completion of police investigation and charge-sheet being filed in a court of law.

These are probably neither bad, nor unimportant, nor avoidable, nor can come within the ambit of any media criticism. I am also not trying to do that, either.

As the saying goes, variety is the spice of life. We, therefore, generally want to get a feel of it everyday early in the morning, mostly glancing through the newspaper headlines, or in the late evening watching impatient anchor with strong personal opinion trying hard to dominate over all other participants in high-decibel ‘TV debates’, as these are called by the respective channels.

In an era of sensationalized and eye-ball grabbing ‘Breaking News’ of all kinds, flashing everywhere almost every now and then, critical health care issues seem to have become a mundane subject to the newsmakers for any meaningful debate to influence the Government. Serious debates on critical health care issues presumably would not generate all important Television Rating Points (TRPs) to the TV channel owners. Though I have no idea, the TRP of such debates  probably has been estimated to be even lesser as compared to the cacophony aired by the TV channels on the cost to exchequer for the MPs subsidized meals in the Indian Parliament…with intermittent high pitch ‘war cry’ of the dominating anchor… ‘the nation wants to know this’.

Conclusion:

Be that as it may, health care environment impacts all of us, quite appreciably. There is not even an iota of doubt on it. However, we can feel it mostly when the reality hits us or our families hard…very hard, as serious and cruel ailments strike suddenly, or as we face avoidable disease related deaths of our near and dear ones, or when illness makes a loving one virtually incapacitated, even after facing financial bankruptcy.

Health care is a serious matter for all of us, just as it is a serious and critical business for every nation and every Government. This criticality factor is independent of whatever level of economic development the country is aspiring for. Thus, the indifference of the Indian Government, if I may say so, despite promising so much on health care earlier this year, is intriguing, and more so, when just 16 percent of the total population has access to free or partially-free health care in our India of the 21st century.

A Great News! But…Would This ‘Golden Goose’ Lay Golden Eggs?

On December 9, 2014, international media flashed across the world a great news item from the Indian pharma industry:

“The first biosimilar of the world’s top-selling medicine Humira (adalimumab) of AbbVie has been launched in India by Zydus Cadila.”

This exhilarating news has undoubtedly got frozen in time flagging a well-cherished moment of pride for the Indian pharmaceutical industry. Along side, taking note of many contemporary factors in this area, a lurking apprehension too does creep in. It raises an awkward and uncomfortable question – would this ‘Golden Goose” born out of a laudable ‘reverse engineering’ effort be able to lay ‘Golden Eggs’, signaling its global commercial success for the company?

In this article, I shall try to dwell on on this important issue.

In one my earlier blog posts of August 25, 2014 titled, “Scandalizing Biosimilar Drugs With Safety Concerns”, I discussed another related concern in this area.

Born a ‘Golden Goose’:

Just to recapitulate, the original product Humira (Adalimumab) of Abbvie, a fully human anti-TNF alpha monoclonal antibody was first globally approved for marketing in 2002. Since then Humira has emerged as the most preferred therapy to reduce the signs and symptoms of patients suffering from moderate to severe rheumatoid arthritis, moderate to severe polyarticular juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, moderate to severe Crohn’s disease and moderate to severe ulcerative colitis. However, Humira is not available in the Indian market, at present.

Zydus Cadila has announced that its biosimilar version of Humira (Adalimumab), has been approved by the Drug Controller General of India (DCGI) and will be marketed under the brand name ‘Exemptia’ for the treatment of autoimmune disorders as indicated for Humira.

As claimed by the company, ‘Exemptia’ is a ‘fingerprint match’ with the original drug Humira in terms of purity, safety and potency. Zydus Cadila has also stated that the novel non-infringing process for Adalimumab and a novel non-infringing formulation have been researched, developed and produced by scientists in its own Research Centre.

With this the world took note of the ‘Golden Goose’, born out of brilliant ‘Reverse Engineering’ in India. However, the apprehension of many continued to linger: Would this ‘Golden Goose’ be able to lay ‘Golden Eggs’?

The product and the price:

According to an estimate, over 12 million patients in India suffer from the above chronic conditions of autoimmune disorders, which progressively deteriorate and lead to lifelong pain and in some cases, even disability. To treat these indications, Exemptia is recommended as a 40 mg subcutaneous injection once every alternate week. Patients normally would have to take the treatment for six months.

Media reports indicate that ‘Exemptia’ of Zydus Cadila will be priced in India equivalent to US$ 200 a vial against Humira price in the United States of US$ 1,000. Initial overall reaction for this local price does not seem to be quite favorable for India.

The global market:

A recent report from Thomson Reuters indicates, as blockbuster drugs with sales turnover of around US$100 billion lose patent protection, the global biosimilars market is expected to grow around US$ 25 billion by the end of the decade.

According to a 2013 report of the credit rating agency Fitch, eight of the current 20 top-selling global pharmaceuticals are biologics that will face patent expiry by 2020.

EvaluatePharma reported that the current the anti-rheumatics market makes up the second largest treatment area by sales, with worldwide revenues of US$ 41.1 billion, closely behind the oncology therapy area, which registered sales of US$68 billion in 2012 with a high growth rate.

The report also states, despite biosimilar entry Anti-rheumatics segment is expected to record a Compound Annual Growth Rate (CAGR) of 4 percent with a turnover of around S$52.1 billion in 2018.

The local potential:

Over the last several years, China and India have been emerging as the promising destinations for international outsourcing of biopharmaceutical manufacturing. In the recent times, China and India are reportedly showing promises to become the industry’s top potential destinations for offshoring over the next five years, ahead of traditional bio manufacturing hubs in the US and Western Europe.

More than 40 biosimilar products are now available in the Indian market. Over 10 pharma players are competing in this area with around 15 epoetin, 8 G-CSF and 4 insulin “biosimilars”, besides a few others.

Although India has the second largest USFDA approved drug manufacturing plants next to the United States, none of the products manufactured in these facilities can possibly be considered as “true biosimilars”.

Humira expected to remain strong:

EvaluatePharma also forecasts that Humira of AbbVie would continue to remain the best selling drug of the world at least till 2018 with sales of US$12.8 billion, despite its US patent expiry in 2016.

Moreover, to succeed Humira that will go off patent between end 2016 and 2018 (Europe), AbbVie reportedly has seven new drugs in clinical development for Rheumatoid Arthritis. These patented new drugs could also significantly cannibalize the sales of Humira.

Physicians’ attitude towards biosimilars:

According to an October 2014 Report of IMS Institute from Europe’s perspective, within each country’s health system, physicians display a range of attitudes and behaviors that influence their prescribing of biosimilars.

IMS observed three broad segments of prescribers as follows:

  • Conservative prescribers: These doctors tend to be late adopters of new technologies, are more likely to follow published clinical treatment guidelines, and may not be aware of or educated on the availability of potential use of biosimilars.
  • Open-minded prescribers: This archetype includes physicians who tend to be the most responsive to new information about treatment options, particularly where experience and knowledge of biologics may be low and educational program can be effective in impacting usage.
  • Enterprising prescribers: This segment of prescribers is most likely to search out information from all sources, and be open to trying different options for patient care including biosimilars as well as innovative treatments.

In addition to these archetypes, the report states, physicians’ attitudes and prescribing behavior may also be influenced or determined by prescribing guidelines, if any, the use of prescribing incentives, as well as the use of promotional activities by either originator or biosimilar manufacturers.

The US biosimilar challenge:

According to reports, despite two pharma players filing biosimilar applications at the USFDA, there are still many issues to be sorted out in this space by the drug regulator of the country.

Though an interchangeable biosimilar in the United States still appears to be several years away, there are initiatives in some American states to restrict interchangeable biosimilar for substitution against the reference product.

Moreover, USFDA’s draft guidance on clinical pharmacology of May 2014 has invited strong adverse comments from the innovator companies, lobby groups and the industry associations.

However, just in the last week, both the innovator companies and biosimilar manufacturers have reportedly agreed to support state legislation that allows pharmacies to automatically substitute biosimilars for corresponding branded biologics. But pharmacies must give prescribers a heads up afterward “within a reasonable time.”

For biosimilars makers, it’s a big improvement on the alternative, as the biotech developers wanted to require pharmacists to check with doctors before making the switch.

That said, the USFDA is yet to determine exactly how to classify biosimilars and their “reference products” as interchangeable. This guidance for classification would be necessary for the above mentioned pharmacy switches. This guidance is important especially for the statutory language, which dictates that interchangeability is proven for “any given patient”. This could also be construed as requiring studies in all the approved indications for a brand name biologic, i.e. Humira has around five different indications.

Thus, the path ahead still remains challenging for the biosimilar players in the United States, and more so for the Indian Companies, as compared to other global pharma majors with deep pockets.

Several other Humira biosimilars under development too:

As indicated earlier, the US and Europe patents of Humira with worldwide sales of US$ 11.02 billion in 2013 would expire by end 2016 and 2018, respectively. Thus, the product has become among the most sought-after biosimilar target prototypes for many pharma and biotech companies across the world.

The global biotech major Amgen has already indicated that its ABP 501 biosimilar has shown comparable efficacy and safety to Humira (adalimumab) in a late-stage trial in patients with moderate-to-severe plaque psoriasis after treatment duration of 16 weeks. The product, reportedly, has also matched Humira in stimulating immune response in patients.

Experts believe, Amgen could be in a position to compete directly with Humira when it loses patent protection, if similar results are obtained in the second phase III trial.

Moreover, according to available reports, Boehringer Ingelheim, Sandoz (Novartis) and Coherus are also progressing well with the development of Humira biosimilars.

Zydus Cadila expects that in 2019 it would be ready to launch the biosimilar of Humira (Adalimumab) in the United States.

Marketing challenges for biosimilars:

Today, the global biosimilars market is indeed in a nascent stage, even for the Indian players.

For successful commercialization of biosimilars, I envisage, a well-crafted hybrid marketing-model of small molecule generics on the one hand and large molecule biologics of the originators’ on the other would be appropriate, in the years ahead.

In the early marketing phase, biosimilar marketers are expected to follow the same branding, communication and detailing strategies of the originators, which ultimately would transform into a generic matrix as more players chip in with the price competition intensifying.

Unlike small molecule generics, affordable price of a biosimilar would be just one of the many critical considerations for its commercial success in the biologics market.

Sustained efforts and initiatives to allay safety concerns with biosimilars among both the doctors and also the patients would be a dire necessity. Providing in-depth medical, technical and domain knowledge to the sales team should never be compromised, though these would require additional initial investments. Post marketing surveillance or pharmacovigilance for biosimilars must be ongoing, even in India. Here too, Indian players do not seem to be very strong, as yet.

Thus, unlike small molecule generics, marketing a large molecule biosimilar would require clear, razor sharp and focused strategies across the value chain to unlock its true potential. Crafting impactful value propositions, avoiding complexities, for each stakeholder, would decide the commercial fate of the product.

‘Made in India’ issue for pharma needs to be addressed expeditiously:

High credibility clinical trial data and manufacturing quality standards would also play a decisive role, especially for India made biosimilars.

This is mainly due to widespread reports of frequent USFDA allegations related to falsification and doctoring of manufacturing data in several manufacturing plants of India.

Ethical and quality issues for drugs made in India, such as these, assumed even greater dimension, as the regulators in France, Germany, Belgium and Luxembourg reportedly suspended marketing approval for 25 drugs over the genuineness of clinical trial data from India’s GVK Biosciences. This is yet another blow to ‘Made in India’ image for medicines, which has arrested the global attention, for all the wrong reasons, just the last week. 

Conclusion:

Considering all the above points, let me now try to make a fair personal guess on whether or not the ‘Golden Goose’ would be successful enough to lay ‘Golden Eggs’, as required by the company.

Firstly, in the Indian perspective, the key point that strikes me is the cost of a treatment course with ‘Exemptia’ per patient in the country. On a rough calculation, it comes around Rs. 1,50,000 per course/per patient. This appears rather high according to the income level of an average Indian.

However, Zydus Cadila expects sales between Rs.1 billion (US$16.16 million) and 2 billion for ‘Exemptia’ only from the Indian market.

I reckon, with relatively high per course treatment cost with Exemptia, it may be quite challenging for the company to achieve this goal in the domestic market.

Thus, the global success of this biosimilar brand would mainly depend on its degree of success in the United States and Europe, post patent expiry of Humira.

Going by the possible availability of other Humira biosimilars from manufacturers with robust global marketing muscle, skill sets, experience and other wherewithal, the path of global success for Exemptia of Zydus Cadila, if the company decides to fly solo, appears to be strewn with many odds.

I would now stick my neck out to zero in with specificity in this area, while envisaging the possible future scenario.

Considering the evolving macro scenario together with the commercial success requirements in this space, I reckon, despite presence of several possible competitors of Humira biosimilars, including one from Zydus Cadila, the biotech domain expertise of Amgen, fuelled by its marketing muscle, would in all probability make its ABP 501 biosimilar the toughest competitor to Humira after its patent expiry in the US and Europe…and then…why doesn’t it try to succeed in India too?

It Took 90 Years To Accept The Dreaded Disease Discovered In A Mental Asylum

In 1908 Dr. Alois Alzheimer discovered a memory erasing, attitude destroying and human dignity stealing deadly disease coined after his name, researching on a patient in a mental asylum.

The disease, in the absence of still any effective treatment, converts a lively human being gradually into a vegetative state, ruthlessly, though the life keeps ticking erratically before it finally extinguishes.

Despite advancement of medical science at a break neck speed, is it not quite surprising that it took 90 years, from 1908 to 1998, to formally accept the root cause of Alzheimer’s disease in the medical science?

Still the greatest mystery of this disease is why it strikes mostly at an advancing age. Other risk factors include ailments such as, diabetes, depression, cardiac conditions and sedentary life style.

I deliberated on this issue in one of my earlier blog posts titled, “Alzheimer’s Disease: Robs Memory: Steals Dignity: Escapes Treatment” of August 11, 2014, though on a different perspective.

A flash back on the disease:

A September 2014 article of Dr. Rod Tanchanco, published in the ‘History News Network’, elucidates how Dr. Alzheimer discovered this deadly disease in a Mental Asylum.

As Dr. Rod Tanchanco narrated, the germination of this discovery started with an orderly and industrious homemaker Auguste, a 50 year old housewife, who started making uncharacteristic mistakes in preparing home meals – a task in which she had been quite proficient for long.

With the progress of time, Auguste gradually started wandering aimlessly around the apartment, leaving many unfinished work in the house. Her attitude and behavioral pattern also started changing noticeably. Concerned with these changes, her husband Carl had no other choice but to take her to the local mental asylum.

The physician’s in the asylum described her as suffering from a weak memory, persecution mania, sleeplessness, and restlessness that rendered her unable to perform physical or mental work. However, the psychiatrist sensed that there was something special about Auguste and Dr. Alois Alzheimer decided that he should see Auguste for himself. The limited treatments included the use of sedatives and warm baths.

After thorough examination, what struck Dr. Alzheimer was Auguste’s relatively young age (51) as he had seen many cases of mental deterioration in much older patients that prompted him to theorize that age-related thickening of the brain’s blood vessels led to brain atrophy.

After about five years of progressive mental and physical decline, Auguste died in 1906. The official cause of death was stated as blood poisoning due to bedsores. However, Dr. Alzheimer suspected that behind her mental illness was a strange disease and perhaps examining her brain would offer some clues.

Discovery of the disease:

When Dr. Alzheimer examined Auguste’s brain sections under the microscope, his inkling was proved to be a reality. He described changes in the neurofibrils – the protein filaments found in brain cells. He also saw peculiar deposits that he referred to as “millet seed-sized lesions.” These pathologic findings, which are now known as neurofibrillary tangles and amyloid deposits, characterize the brains of patients suffering from Alzheimer’s Disease.

Skeptical initial response:

As Dr. Rod Tanchanco highlights, Dr. Alzheimer’s discovery was not immediately well received, as correlating mental or neurologic disorders with histopathologic findings was not firmly established nor accepted by his peer groups at that time.

Acceptance after long 90 years:

Ninety years later, in 1998, researchers re-examined Auguste’s original brain sections and confirmed the presence of neurofibrillary tangles and amyloid plaques. There is still no cure of this life-threatening disease, and the burden on the afflicted continue to remain mind-boggling.

According to Dr. Tanchanco, one of the most prominent psychiatrists in the early 1900s called Emil Kraepelin, first mentioned the term ‘Alzheimer’s Disease’ in the 1910 edition of his textbook on psychiatry. The disease was still poorly understood, but one of the most famous medical eponyms was born with it.

Where are we today?

All current treatments for Alzheimer’s cannot stop the underlying decline and death of brain cells. Thus, as more cells die, Alzheimer’s continues to progress.

Experts are cautiously hopeful about developing Alzheimer’s treatments that can stop or significantly delay the progression of Alzheimer’s. A growing understanding of how the disease disrupts the brain has led to potential Alzheimer’s treatments that short-circuit fundamental disease processes.

A laudable initiative has come to the fore recently in this arena. Having experienced something like the ‘law of diminishing return’ in pursuit of high resource intensive R&D projects aimed at critical disease areas such as Alzheimer’s, 10 big global pharma majors reportedly decided in February 2014 to team up with the National Institutes of Health (NIH) of the United States in a ‘game changing’ initiative to identify disease-related molecules and biological processes that could lead to future medicines.

This Public Private Partnership (PPP) for a five-year period has been named as “Accelerating Medicines Partnership (AMP)”. According to the report, this US federal government-backed initiative would hasten the discovery of new drugs in cost effective manner focusing first on Alzheimer’s disease, Type 2 diabetes, and two autoimmune disorders: rheumatoid arthritis and lupus. The group considered these four disease areas among the largest public-health threats, although the span of the project would gradually expand to other diseases depending on the initial outcome of this project.

New drug development concepts:

A. Two new treatment approach strategies:

The protein beta-amyloid (plaques) has long been considered a sign of Alzheimer’s disease. Some of the new Alzheimer’s treatments in development target microscopic clumps of plaques.

According to Mayo Clinic, beside other studies, following are the two newer strategies aimed at beta-amyloid (plaques):

  • Immunization strategies:

Most current immunization studies focus on administering antibodies against beta-amyloid from outside sources instead of enhancing a person’s immune system.

One large research effort is exploring the value of intravenous (IV) infusions of a product derived from donated blood. This product contains naturally occurring anti-amyloid antibodies from the donors.

Some other studies are investigating laboratory-engineered (monoclonal) antibodies.

  • Production blockers:

This may reduce the amount of beta-amyloid formed in the brain. Research has shown that beta-amyloid is produced from a “parent protein” in two steps performed by two different enzymes. Several experimental drugs aim to block the activity of the two enzymes.

B. The concept of heart-head connection:

Another interesting area, among many, that the Mayo Clinic highlights is the concept of heart-head connection.

Growing evidence suggests that brain health is closely linked to heart and blood vessel health. Our arteries nourish our brain. The risk of developing Alzheimer’s appears to increase as a result of many conditions that damage the heart or arteries. These include high blood pressure, heart disease, stroke, diabetes and high cholesterol.

In addition, a strong genetic Alzheimer’s risk factor is one form of a gene for a protein that carries cholesterol in the blood (apolipoprotein E). Strategies under this concept include:

- Available drugs for heart disease risk factors: Researchers are investigating whether drugs now used to treat high blood pressure, diabetes and high cholesterol may also help people with Alzheimer’s or reduce the risk of developing the disease.

- Drugs aimed at new targets: Additional projects are looking more closely at how the connection between heart disease and Alzheimer’s works at the molecular level to find new drug targets.

- Lifestyle choices: Researchers have explored whether lifestyle choices with known heart benefits, such as exercising on most days and eating a heart-healthy diet, may help prevent Alzheimer’s disease or delay its onset.

A large new database of Alzheimer’s disease patients:

Meanwhile, the Coalition Against Major Diseases (CAMD), which is a formal consortium of pharmaceutical companies, research foundations and patient advocacy/voluntary health associations, with advisors from federal agencies, has released a new database of more than 4,000 Alzheimer’s disease patients who have participated in 11 industry-sponsored clinical trials.

According to the Critical Path Institute, which oversees the coalition, this is the first database of combined clinical trials to be openly shared by pharmaceutical companies and made available to qualified researchers around the world. It is also the first effort of its kind to create a voluntary industry data standard that will help accelerate new treatment research on brain disease, as patients with other related brain diseases are expected to be added.

A large number of researchers believe that sharing these data from more than 4,000 study participants will speed development of more-effective therapies.

CAMD is funded by a cooperative agreement with the USFDA and a matching grant from the Science Foundation Arizona.

Conclusion:

It took 90 years to accept the cause of this memory erasing, attitude destroying and human dignity stealing deadly disease that was first discovered in a mental asylum by Dr. Alois Alzheimer.

Thereafter, discovering a safe an effective medicine for the treatment of Alzheimer’s disease has rather been very slow, if not frustrating, especially for the afflicted patients and their families. Some global pharma majors have even announced jettisoning research initiatives in this area.

Even with the application of modern day’s cutting edge science and technology, it is still difficult to fathom, how many years would still remain in waiting for a breakthrough treatment option for Alzheimer’s disease.

In a scenario like this, even today, the very thought of becoming a victim of this life-threatening disease sends shivers down the spine of many.

Alzheimer’s Disease: Robs Memory: Steals Dignity: Escapes Treatment

At a well reputed Mumbai Club, quite unexpectedIy, I bumped into Sumeet (name changed). It has indeed been a long while since we met at his home in South Mumbai. He came there with his wife Shilpa (name changed). Sumeet, was literally an icon of yesteryears in every respect, a bright engineer with MBA and a much-accomplished leader of his time who retired at the turn of the new millennium.

“How are you Sumeet da?”, I started off cheerfully, as he was looking all around.

“Very well, very well and you?”, he replied softly with a faint quivering of his lips, but without any eye contact.

“I am good Sumeet da, but have you recognized me?” I queried with apprehension.

Turning his face towards Shilpa, Sumeet hesitatingly replied, “No. But have we met before?”

The innocent question struck me as lightning from nowhere, making me a bundle of emotion momentarily. With a lump in my throat and clenching my fists, I struggled hard to regain my composure.

Sumeet, one of the the brightest of brights, from earlier years of our generation, is now a victim of a dreaded illness called Alzheimer’s Disease (AD). The disease has robbed him of his priceless memory, changed his behavior beyond recognition, kidnapped him from his own self, and has stolen most of his much-valued dignity in life, mercilessly.

Alzheimer’s Disease (AD) in brief:

Alzheimer’s Disease (AD), as known to many, is the most common form of dementia, accounting for 60 to 80 percent of all cases, that results in serious memory loss and other intellectual and behavioral traits of individuals, serious enough to interfere with a person’s daily life and tasks.

AD has been defined as, a neurodegenerative type of dementia, in which the death of brain cells causes memory loss and cognitive decline. The total brain size shrinks with AD, as the tissue has progressively fewer nerve cells and connections. Brains affected by AD would always show tiny inclusions in the nerve tissue, called plaques and tangles.

Plaques are found between the dying cells in the brain – from the build-up of a protein called beta-amyloid, while the tangles are within the brain neurons and from a disintegration of another protein, called tau.

Though the abnormal protein clumps and inclusions in the brain tissues are always present in AD, there could be another underlying process also that is actually causing the disease, which scientists are not sure of, as yet.

Be that as it may, with the progression of the disease, besides memory loss, AD precipitates other serious symptoms, such as, deepening confusion about events, time and place; mood and behavior changes; unfounded suspicions about family, friends and even professional caregivers; disorientation; other behavior changes; then difficulty speaking, swallowing and walking. At a late stage, the patients lose the ability to carry on even a conversation and respond to their environment.

Cause:

Although the causes of AD are not quite clear to the scientists, as yet, the disease results from a combination of genetic, lifestyle and environmental factors that adversely affect the brain over a period of time.

Scientists opine that in less than 5 percent of the cases, the causative factors of the AD are specific genetic changes that can almost definitively indicate that a person would develop AD. According to published reports, while the strongest risk gene found so far is apolipoprotein e4 (APOE e4), other risk genes have not been conclusively confirmed, just yet.

Survival rate:

According to published reports, the survival rate of AD patients, after their symptoms become noticeable to others, can range from 4 to 20 years, depending on health conditions, the average being 8 years. In the United States, AD is the sixth leading cause of death.

Not a normal part of the aging process:

Although majority of people with AD are over 60 years of age, it is not just a disease of old age. Up to 5 percent of cases the disease may strike even younger people in 40s or 50s. Women are found to be more prone to AD than men.

Prevalence:

The World Health Organization (WHO) declared dementia, in general, as a priority condition in 2008, through the Mental Health Gap Action Program.

Each year, the total number of new cases of dementia worldwide has been reported as nearly 7.7 million, which means one new case every four seconds.

According to AC Immune SA of Switzerland, AD will be one of the biggest burdens of the future society showing dramatic incidence rates. Over 44 million people were now affected with AD worldwide. Since the incidence and prevalence of AD increase with age, the number of patients will grow dramatically as our society gets older. By 2050 the patient numbers are expected to triple, touching 135 million AD patients worldwide.

India:

According to another report titled, “Priority Medicines for Europe and the World – A Public Health Approach to Innovation” By Béatrice Duthey, Ph.D published on 20 February 2013, the fastest growth of AD in the elderly population is now taking place in China, India, and their south Asian and western Pacific neighbors and has become a major public health concern as the population ages.

AD is the most common kind neurodegenerative disease in India. There are reportedly around 5 million dementia patients in the country of which, roughly 70 to 80 per cent have AD. This number is expected to double by 2030, and the costs involved are expected to increase three times. Besides drugs, costs of ‘care giving’ for AD patients are also expected to rise significantly.

The market and economic impact:

According to AC Immune SA, AD market is currently estimated at US$ 5 billion annually and is expected to exceed US$ 20 billion by 2020.

The global economic impact of AD is shown by its worldwide cost of US$ 640 billion, exceeding 1 percent of gross world product. It can be seen as the most significant health crisis in the 21st century. The 2010 annual costs of treating and caring for patients was  $183 billion in the US alone. This figure is expected to increase to $ 1.1 trillion in 2015.

AD is becoming the third most expensive disease, counting for 30 percent of the US healthcare costs. The medical costs for Alzheimer´s Disease patients are three times higher than for other older patients. Moreover, AD patients mostly live at home resulting in high impact on family’s health, emotional well being, as well as their employment and financial security.

India:

Many elderly people in India live with AD without any treatment, accepting the condition as an unavoidable one and related to the aging process of an individual.

The present day costs of maintaining a patient with AD in India, who has been diagnosed, are reportedly any where between Rs. 50,000 to Rs. 4,50,000. Additionally, many elderly couples are just not frail and living alone these days, as their children may be working in a far off country.

Currently, AD market in India is reportedly around US$ 50 million, growing around 25 percent. More disease awareness initiatives are expected to accelerate the market growth by manifold. Sun Pharma is the market leader in the AD segment. Other, key players are Dr. Reddy’s Laboratories (DRL), Torrent, Glenmark, Ranbaxy, Cipla and Alkem

In fact, Cipla recently reportedly announced an investment of US$ 21 million in Chase Pharmaceuticals of the United States, which is an early-stage drug development company focused on developing novel approaches to improve treatments for Alzheimer’s disease.

In addition, DRL is also making rapid strides in this area. In 2013, the company launched generic Donepezil Hydrochloride tablets for AD in the US market.

Treatment:

There is no cure for AD as of date. There is no disease-modifying treatment for AD even in the global market, either.

Since 2003, there has not been any single innovative drug launched in the global market either for prevention or cure of AD. The available drugs cannot stop the progression of the disease. They just temporarily slow the worsening of dementia symptoms. The situation gets even more complicated as the disease is usually diagnosed late, when already 70 percent of the nerve cells in the brain are dead.

Global researchers are looking for new treatments to alter the course of the disease and improve the quality of life for people suffering from this dreaded disease.

For the treatment of AD, the U.S. Food and Drug Administration (FDA) has approved two types of medications, namely,

-      Cholinesterase inhibitors, such as, Aricept, Exelon, Razadyne, Cognex

-      Memantine, such as, Namenda to treat the cognitive symptoms (memory loss, confusion, and problems with thinking and reasoning) of the disease.

Many doctors prescribe both types of medications together, along with Vitamin E for cognitive changes.

However, Aricept is the only cholinesterase inhibitor approved to treat all stages of AD, from moderate to severe.

Although, Tacrine (Cognex) was the first cholinesterase inhibitor approved, very few doctors prescribe this drug today because of more serious side effects.

According to The Alzheimer’s Association, the world’s leading voluntary health organization in Alzheimer’s care, support and research; the current treatments for AD at a glance are as follows:

Treatments at a glance:

Generic Brand Approved For Side Effects
donepezil Aricept (Eisai/Pfizer) All stages Nausea, vomiting, loss of appetite and increased frequency of bowel movements.
galantamine Razadyne (Janssen) Mild to moderate Nausea, vomiting, loss of appetite and increased frequency of bowel movements.
memantine Namenda/Ebixa (Actavis/Lundbeck) Moderate to severe Headache, constipation, confusion and dizziness.
rivastigmine Exelon (Novartis) Mild to moderate Nausea, vomiting, loss of appetite and increased frequency of bowel movements.
tacrine Cognex (Pfizer) Mild to moderate Possible liver damage, nausea, and vomiting.
vitamin E Not applicable Not approved Can interact with antioxidants and medications prescribed to lower cholesterol or prevent blood clots; may slightly increase risk of death.

India:

In India the treatment is much the same. Besides, patented versions, relatively cheaper generic equivalents of all these drugs are available in the country.

On going drug trials: 

As there are no effective therapies for AD, this therapy segment remains at the top of the list for unmet needs, globally. Disease-modifying therapies could transform this market appreciably.

At the Alzheimer’s Association International Conference held in Copenhagen, Denmark from July 12 to 17, 2014, scientists described five trials that may prevent the onset of the neurodegenerative disease in people not yet experiencing cognitive decline, as follows:

  • Gantenerumab and Solanezumab: Two experimental drugs, , both of which are antibodies designed to bind to amyloid and prevent it from forming brain-damaging plaques.
  • Solanezumab: An experimental anti-amyloid compound.
  • The trial will first pilot a screening test for two genes to see if it can accurately predict risk of mild cognitive impairment. The next phase of the trial will test an experimental compound designed to delay symptoms of mild cognitive impairment and Alzheimer’s disease in people without symptoms.
  •  Crenezumab: Anti-amyloid antibody
  •  An immunotherapy that prompts the body’s immune system to produce antibodies against amyloid protein, and a beta-secretase inhibitor that blocks the production of certain forms of amyloid.

According to Alzheimer’s Disease Therapeutics and Diagnostics: World Market 2013-2023 the following global players hold greatest potential. In particular, the analysis investigates these companies:

• Pfizer
• Eisai
• Actavis
• Lundbeck
• Novartis
• TauRx Therapeutics
• AC Immune.

A large pharma industry association of the United States has indicated in a report that dedicated researchers are currently working on nearly 100 medicines in development for Alzheimer’s and other dementias. These could give future patients a new hope for a future free of AD.

Conclusion:

AD can strike anyone at any time without any visible warning whatsoever. It then robs the person’s memory, steals the individual’s dignity of life, evades all available current treatments, till it is able to extinguish slowly and agonizingly the last flicker of life, mostly much sooner than otherwise it would have been.

Like many other countries, India – the world’s 2nd largest population, is also facing a crisis in dealing with the growing number of AD patients.

These patients require constant support from family/professional caregivers along with medical attention. The progression of the disease leaves patients mostly in semi-vegetative states, at times for years.

If no cure is available for AD, arresting the disease progression becomes a major health challenge in the country. Currently only short term symptomatic treatment is available. Neither is there any organized mechanism for early diagnosis of AD with specific markers, which could lead to early intervention with the most appropriate and effective drugs to address the disease sooner.

Alzheimer’s Disease that turns millions of otherwise boisterous individuals, like Sumeet, into living dead, snatching away everything that a life would possibly demand at its minimum, must feature in the areas of focus of the new national heath policy of India under the new dispensation.

“Meeting Unmet Needs of Patients”: A New Direction

The much-hyped phrase of the global pharma majors – ‘meeting unmet needs of patients’, is very often used to create an aura around newer patented drugs of all kinds, from original to banal, including evergreen varieties such as:

Evergreen Drug/Brand Medical Condition Original Drug/Brand
Levocetirizine (Vozet) Allergies Cetirizine (Zyrtec)
Escitalopram (Lexapro) Depression Citalopram (Celexa)
Esomeprazole (Nexium) Acid reflux Omeprazole (Prilosec)
Desloratadine (Clarinex) Allergies Loratadine (Claritan)
Pregabalin (Lyrica) Seizures Gabapentin (Neurotonin)

I do not have any terrible issue with this usage, as many stakeholders, including various governments, have already started differentiating between the ‘Chalk’ and the ‘Cheese’ kinds of patented products and contemplating future course of action, accordingly. The recent development in South Africa is one such example.

That said, there is now a greater need to ponder over the much bigger picture in the same context and direction, which would improve predictability of treatment outcomes by manifold. Simultaneously, such R&D initiatives would help reducing the overall cost, especially for dreaded diseases like cancer, mainly through highly targeted drugs and consequently avoiding the risk and associated wastage, as often happens with the prevailing ‘trial and error’ therapy approach, thereby benefitting the patients immensely. This is mainly because no drug is 100 percent effective with inconsequential side-effects for all patients of any disease type.

Genetics and Genomics Science made it possible:

With already acquired knowledge in genetics, genomics and genome sequencing capability, it is now possible to precisely predict a person’s susceptibility to various disease types and proactively working out measures to help either avoiding ailments, such as, non-infectious life threatening and chronic diseases altogether, if not, making their treatment more predictable and less expensive, as stated above.

If organized efforts are made to extend the application and benefits of this science to a larger section of population, those R&D initiatives can really be construed, unquestionably, as ‘meeting unmet needs of the patients’, just as ‘first in kind’ category of innovative drugs are recognized by the scientific community and the civil society as a whole.

A treatment revolution in the offing:

Expectations are rapidly building up that evolving genetics and genomics science based technological know-how would ultimately revolutionize the practice of medicine ushering-in the pathway of personalized medicine for a large number of patients.

Definition: 

A report from the Tufts Center for the Study of Drug Development defines personalized medicine as “Tailoring of medical treatment and delivery of health care to individual characteristics of each patient, including their genetic, molecular, imaging and other personal determinants. Using this approach has the potential to speed accurate diagnosis, decrease side effects, and increase the likelihood that a medicine will work for an individual patient.”

The aim: 

The aim of personalized medicine is, therefore, to make a perfect fit between the drug and the patient. It is worth noting that genotyping is currently not a part of clinically accepted routine. However, it is expected to acquire this status in the western world, shortly.

To give a very quick example, genetic differences within individuals determine how their bodies react to drugs such as Warfarin – a blood thinner taken to prevent clotting. It is of utmost importance to get the dosing right, as more of the drug will cause bleeding and less of it will not have any therapeutic effect.

In the field of cancer, genetic tests are now being done by some oncologists to determine which patients will be benefited most; say with Herceptin, in the treatment of breast cancer.

Thus, with personalized medicine the health of a patient will be managed based on personal characteristics of the individual, including height, weight, diet, age, sex etc. instead of defined “standards of care”, based on averaging response across a patient group. Pharmacogenomics tests like, sequencing of human genome will determine a patient’s likely response to drugs.

Disease prevention: 

In addition, such medicines would help identifying individuals prone to serious ailments such as, metabolic, cardiac, endocrine, auto-immune, psychosomatic, including cancer of various types; enabling physicians to take appropriate preventive measures much before disease manifestations and in that process would help containing the overall treatment cost.

Cost of genome sequencing:

Sir John Bell, Professor of Medicine at Oxford University, reportedly said in early December 2012 that personalized medicine for all could soon be a clear possibility, as everybody will be able to have their entire DNA make-up mapped for as little as £100 (Rs.10, 000 approx.).

This estimate seems to be realistic, as the price of genome sequencing has fallen by 100,000-fold in 10 years. This cost is expected to further decline, as genome of any person essentially remains unchanged over time. Thus, this information might become a part of an individual’s medical record allowing the doctors to use it as necessary.

Summary of key advantages: 

To summarize, the expected benefits from personalized medicine, besides very early diagnosis as stated above, are the following:

1. More Accurate Dosing: Instead of dose being decided based on age and body weight of the patients, the physicians may decide and adjust the dose of the medicines based on the genetic profiling of the patients.

2. More Targeted Drugs: It will be possible for the pharmaceutical companies to develop and market drugs for patients with specific genetic profiles. In that process, a drug needs to be tested only on those who are likely to derive benefits from it. This in turn will be able to effectively tailor clinical trials, expediting the process of market launch of these drugs.

3. Improved Healthcare: personalized medicine would enable the physicians to prescribe ‘the right dose of the right medicine the first time for everyone’ without any trial or error approach, resulting in much better overall healthcare.

Current use:

Though these are still the early days, initial usage of personalized medicine is now being reported in many areas, such as:

Genetic analysis of patients dealing with blood clots: Since 2007, the U.S. Food and Drug Administration has been recommending genotyping for all patients being assessed for therapy involving Warfarin.

Colorectal cancer: For colon cancer patients, the biomarker that predicts how a tumor will respond to certain drugs is a protein encoded by the KRAS gene, which can now be determined through a simple test.

Breast cancer: Women with breast tumors can now be effectively screened to determine which receptors their tumor cells contain.

In addition, this approach would also help clinicians to determine which particular therapy is most likely to succeed on which patient.

Present outlook: 

A September 2013 article published in Forbes Magazine titled, “Personalized Medicine May Be Good For Patients But Bad For Drug Companies’ Bottom Line” says, although personalized medicine offers tremendous potential for patients, because of the dual burdens of expensive clinical trials and diminished revenue potential, the concept may become unsustainable in the long term, the attitude of regulators will be critical to drug companies’ willingness to embrace personalized medicine, and to its wider application.

In my view, for greater interest of patients to ‘meet their unmet needs’ global pharma, majors, academics, respective governments and the drug regulators should find a way out in this new direction, sooner.

Indian initiatives:

Some companies, both well known and lesser known, are making collaborative progress, keeping low profile, in the genome sequencing area in India, which will ultimately make expensive treatments, such as cancer, more predictable and simultaneously affordable to many.

The concerns:

While the progress in the field of personalized medicine is quite heartening, some experts have reportedly been sounding a note of caution. They strongly feel that DNA code sequencing brings to light a “very real privacy concerns” of individuals.

The key argument being, if genome sequencing is extended to entire population, individuals and their relatives could then be identified and tracked by matching their DNA with the genome stored in the respective health records. This move, as contemplated by the opponents, could “wipe out privacy” with a significant impact on the society.

A paper published in ‘Scientific American’ dated January 2014, titled “What Fetal Genome Screening Could Mean for Babies and Parents” deliberated that today doctors are closer than ever before to routinely glimpsing the full genetic blueprints of a fetus just months after sperm meets egg. That genomic reconstruction would reveal future disease risk and genetic traits even as early as the first trimester of pregnancy – raising another ethical issue that could hugely impact parents’ decision threshold for deciding to terminate a pregnancy or influencing how they rear their child.

Thus, all these ethical and social issues in the development and usage of personalized medicine must be appropriately addressed under a well deliberated ethical, social, legal and regulatory framework of each country.

Conclusion:

Though in Europe and to some extent in the United States, treatments based on personalized medicine have already been initiated, we are still in a nascent stage for this novel concept to get translated into reality for the benefit of a much wider population across the world.

Lot of grounds may still need to be covered, especially in the realm of medical research and also to work out the regulatory pathways for personalized medicine in healthcare by the pioneers of this great concept and more importantly by effectively addressing the ethical concerns raised on this subject.

If collaborative initiatives are taken jointly by academia, R&D based global pharma majors and medical diagnostic players towards this new direction with a clearer focus and  supported by the law makers, a huge unmet needs of patients will truly be met, giving yet again a fresh impetus to the much hyped phrase “Meeting Unmet Needs of Patients”, though in a refreshingly new direction.

Vaccines Development: Is it Just a Business Based on Fear?

‘Vaccination – A Business based on fear’, is the title of a book written by Dr. Gerhard Buchwald M.D, a German medical doctor and a vaccination critic. This book talks about:

“The damage and the deaths caused by vaccination are written off as ‘pure coincidence’, as something which would have occurred anyway, even without vaccination. Often damage is trivialized by claiming that vaccine damage occurs only very, very rarely, or the damage is covered up by naming as the cause, the most unlikely syndromes which can only be found in special literature.”

However, his critics and pro-vaccination experts do opine that this book “is a pathetic presentation of vaccination, from a self-proclaimed anti-vaccination lobbyist. It is full of half-truths, blatant lies and misrepresented statistics”.

Vaccination – one of the most important development in medicines: 

Quite in contrary to what Dr. Gerhard Buchwald wrote, vaccination was voted as one of the four most important developments in medicine of the past 150 years, alongside sanitation, antibiotics and anesthesia by readers of the ‘British Medical Journal’ in 2007. No wonder, Vaccines are one of the most successful and cost-effective public health interventions, which help preventing over 3 million deaths every year throughout the world topping the list in terms of lives saved.

Vaccines that are being developed and marketed today, though provide high level of protection against increasing number of diseases with reduction of associated morbidity and mortality, there is still a crying need for greater encouragement, more resource deployment and sharper focus towards newer vaccines development for many more dreaded and difficult diseases.

In tandem, concerted efforts need to be made by both the industry and the government to improve affordable access to all these vaccines for a larger section of the population, especially in the developing world.

Rejuvenating trend:

However, from the business perspective, the vaccine market, though initially considered to be a low-profit initiative, now has started being under rejuvenated focus keeping pace with improved understanding of the human immune system. The future scope of vaccines is immense, as the management of several potentially preventable diseases remains still unaddressed.

Consequently, the focus of the global vaccine industry is getting expanded from prophylactic vaccination for communicable disease (e.g. DTP vaccine) to therapeutic vaccines (e.g. Anti-cancer vaccines) and then possibly non-communicable disease vaccines (e.g. vaccines for coronary artery disease).

Shifting focus on vaccines types:

As per the ‘National Institute of Health (NIH)’ of USA, following are some types of vaccines that researchers usually work on:

  • Live, attenuated vaccines
  • Inactivated vaccines
  • Subunit vaccines
  • Toxoid vaccines
  • Conjugate vaccines
  • DNA vaccines
  • Recombinant vector vaccines

Among all these segments, sub-unit vaccine is the largest revenue generator, though synthetic vaccines, recombinant vector vaccines, and DNA vaccines are emerging as the fastest-growing segments.

The first vaccine of the world:

In 1796, Edward Anthony Jenner not only discovered the process of vaccination, alongside developed the first vaccine of the world for mankind – smallpox vaccine. To develop this vaccine Jenner acted upon the observation that milkmaids who caught the cowpox virus did not catch smallpox.

As per published data prior to his discovery the mortality rate for smallpox was as high as up to 35%. Thus, Jenner is very often referred to as the “Father of Immunology”, whose pioneering work has “saved more lives than the work of any other person.”

Later on in 1901 Emil Von Behring received the first Nobel Prize (ever) for discovering Diphtheria serum therapy.

R&D costs for vaccines:

According to a paper published by the US National Library of Medicine and National Institute of Health (NIH):

“A vaccine candidate entering pre-clinical development in 2011 would be expected to achieve licensure in 2022; all costs are reported in 2022 Canadian dollars (CAD). After applying a 9% cost of capital, the capitalized total R&D expenditure amounts to $ 474.88 million CAD.”

Issues and challenges:

To produce a safe and effective marketable vaccine, besides R&D costs, it takes reportedly around 12 to 15 years of painstaking research and development process.

Moreover, one will need to realize that the actual cost of vaccines will always go much beyond their R&D expenses. This is mainly because of dedicated and highly specialized manufacturing facilities required for mass-scale production of vaccines and then for the distribution of the same mostly using cold-chains.

Around 60% of the production costs for vaccines are fixed in nature (National Health Policy Forum. 25. January 2006:14). Thus such products will need to have a decent market size to be profitable.

Unlike many other medications for chronic ailments, which need to be taken for a long duration, vaccines are administered for a limited number of times, restricting their business potential.

Thus, the long lead time required for the ‘mind to market’ process for vaccine development together with high cost involved in their clinical trials/marketing approval process, special bulk/institutional purchase price and limited demand through retail outlets, restrict the research and development initiatives for vaccines, unlike many other pharmaceutical products.

Besides, even the newer vaccines will mostly be required for the diseases of the poor, like Malaria, Tuberculosis, HIV and ‘Non Communicable Diseases (NCDs)’ in the developing countries, which may not necessarily guarantee a decent return on investments for vaccines, unlike many other newer drugs. As a result, the key issue for developing a right type of newer vaccine will continue to be a matter of pure economics.

A great initiative called GAVI: 

Around 23 million children of the developing countries are still denied of important and life-saving vaccines, which otherwise come rather easily to the children of the developed nations of the world.

To resolve this inequity, in January 2000, the Global Alliance for Vaccines and Immunization (GAVI) was formed. This initiative was mainly aimed at generating sufficient fund to ensure availability of vaccines for children living in the 70 poorest countries of the world.

The GAVI Alliance has been instrumental in improving access to six common infant vaccines, including those for hepatitis B and yellow fever. GAVI is also working to introduce pneumococcal, rotavirus, human papilloma virus, meningococcal, rubella and typhoid vaccines in not too distant future.

In August 2013, GAVI has reportedly launched a campaign in Kenya to fight the world’s leading killer of children under five with a new Pneumococcal Vaccine for prevention from pneumonia, meningitis and sepsis, which kill more than half a million people a year.

GAVI hopes to avert 700,000 deaths by 2015 through the immunization of 90 million children with pneumococcal vaccines.

Global pharma majors Pfizer and GlaxoSmithKline (GSK) are producing the vaccines as a part of a deal part-funded by Britain, Italy, Canada, Russia, Norway and the Bill Melinda Gates Foundation.

Current trend in newer vaccine development:

Malaria Vaccine:

According to the National Institute of Health (NIH) of the United States, the results of an early-stage clinical trial published in August 8, 2013 in the ‘Journal Science’ for an investigational malaria vaccine has been found to be safe to generate an immune system response and to offer protection against malaria infection in healthy adults.

The scientists at Sanaria Inc., of Rockville, Md. Research Center developed this vaccine known as PfSPZ. The researchers reportedly found that injecting patients with live-but-weakened malaria causing parasites appeared to create a protective effect.

Earlier, Reuters on December 20, 2011 reported that the British scientists have developed an experimental malaria vaccine, which has the potential to neutralize all strains of the most deadly species of malaria parasite.

In October 2011, the data published for a large clinical trial conducted in Africa by GlaxoSmithKline on their experimental malaria vaccine revealed that the risk of children getting malaria had halved with this vaccine. Reuters also reported that other teams of researchers around the world are now working on different approaches to develop a malaria vaccine.

Tuberculosis vaccines:

The Lancet reported in March 2013, as BCG vaccination provides incomplete protection against tuberculosis in infants, a new vaccine, modified Vaccinia Ankara virus expressing antigen 85A (MVA85A), has been designed to enhance the protective efficacy of BCG. MVA85A was found well-tolerated and induced modest cell-mediated immune responses. However, the reasons for the absence of MVA85A efficacy against tuberculosis or M tuberculosis infection in infants would need exploration.

Universal Cancer vaccines:

In a breakthrough development, the Israeli company Vaxil BioTherapeutics has reportedly formulated a therapeutic cancer vaccine, now in clinical trials at Hadassah University Medical Center in Jerusalem.

If everything falls in place, the vaccine could be available about six years down the road, to administer on a regular basis not only to help treating cancer but also to keep the disease from recurring.

Though the vaccine is being tested against a type of blood cancer called multiple myeloma, if it works as the initial results indicate, its platform technology VaxHit could be applied to 90 percent of all known cancers, including prostate and breast cancer, solid and non-solid tumors.

HIV Vaccine:

A recent effort to find a vaccine for HIV is reportedly beginning in 2013 at laboratories in a London hospital and two centers in Africa. The work will be split equally between London, the Rwandan capital Kigali and Nairobi in Kenya.

It has been reported that scientists are recruiting 64 healthy adult volunteers for the trial, which is expected to take up to two years.

Vaccines requirements of the developing world: 

Developing countries of the world are now demanding more of those vaccines, which no longer feature in the immunization schedules of the developed nations. Thus to supply these vaccines at low cost will be a challenge, especially for the global vaccine manufacturers, unless the low margins get well compensated by high institutional demand.

India needs a vibrant vaccine business sector:

For greater focus on all important disease prevention initiatives, there is a need to build a vibrant vaccine business sector in India. To achieve this objective the government should create an enabling ecosystem for the vaccine manufacturers and the academics to work in unison. At the same time, the state funded vaccine R&D centers should be encouraged to concentrate more on the relevant vaccine development projects ensuring a decent return on their investments, for longer-term economic sustainability.

More often than not, these stakeholders find it difficult to deploy sufficient fund to take their vaccines projects successfully through various stages of clinical development in order to obtain marketing approval from the drug regulator, while registering a decent return on investments. This critical issue needs to be appropriately and urgently addressed by the Government to make the disease prevention initiatives in the country sustainable.

Changing market dynamics: 

Even in a couple of decades back, ‘Vaccines Market’ in India did not use to be considered as a focus area by many pharmaceutical companies. Commoditization of this market with low profit margin and unpredictable interest of the government/the doctors towards immunization were the main reasons. Large global players like Glaxo exited the vaccine market at that time by withdrawing products like, Tetanus Toxoid, Triple Antigen and other vaccines from the market.

Currently, the above scenario is fast changing. The vaccine market, as stated above, is getting rejuvenated not only with the National Immunization Program (NIP) of the country, but also with the emergence of newer domestic vaccines players and introduction of novel vaccines by the global players, which we shall discuss below.

In addition, the ‘Indian Academy of Pediatrics (IAP) Committee on Immunization’ now recommends the ‘best individual practices schedule’ for the children in consultation with their respective parents. Such schedule may not conform to NIP and include newer vaccines, broadening the scope of use of vaccines in general.

Global Market:

According to GBI Research Report, overall global vaccines market was valued at US$ 28 billion in 2010 and is expected to reach US$ 56.7 billion by 2017 with a CAGR of 11.5%. The key growth driver of this segment will be introduction of newer vaccines, which are currently either in the regulatory filing stage or in the late stages of clinical development.

The important international players in the vaccines market are GlaxoSmithKline, Sanofi, Pfizer, Novartis AG, Merck and SP-MSD. Together they represent around 88% of the total vaccine segment globally, the report highlights.

Indian Market:

McKinsey in its report titled, “India Pharma 2020: Propelling access and acceptance, realizing true potential“ stated that at 2% penetration, the vaccines market of India is significantly under-penetrated with an estimated turnover of around US$ 250 million, where the private segment accounts for two-thirds of the total. McKinsey expects the market to grow to US$ 1.7 billion by 2020.

India is one of largest markets for all types of vaccines in the world. The new generation and combination vaccines, like DPT with Hepatitis B, Hepatitis A and Injectable polio vaccine, are driving the growth. The demand for veterinary vaccines is also showing ascending trend. Pediatric vaccines contribute to around 60% of the total vaccines market in India.

Domestic Indian players like, Serum Institute, Shantha Biotecnics, Bharat Biotech and Panacea Biotech are poised to take greater strides in this direction. Bharat Biotech is incidentally the largest Hepatitis B vaccine producer in the world. Likewise, Serum Institute is reportedly one of the largest suppliers of vaccines to over 130 countries and claim that ’1 out of every 2 children immunized worldwide gets at least one vaccine produced by Serum Institute.’

The first new vaccine developed in India:

Indian scientists from Bharat Biotech Ltd in Hyderabad have reportedly developed a new oral vaccine against the Rotavirus induced diarrhea, where both vomiting and loose motion can severely dehydrate children very quickly. This is the first new vaccine developed in India, establishing itself as the first developing country to achieve this unique distinction.

Two recent vaccine JV and Partnership agreements in India:

British drug major GlaxoSmithKline (GSK) has reportedly agreed to form a 50-50 venture with the domestic Indian vaccine manufacturer Biological E Limited in January 2013 to develop a product that would combine GSK’s injectable polio shot with a vaccine produced by Biological E to protect against five diseases including diphtheria and tetanus.

In addition, MSD pharma of the United States and Indian drug major Lupin have announced a partnership agreement to market, promote and distribute, MSD’s 23-valent Pneumococcal Polysaccharide Vaccines under a different brand name in India for prevention of Pneumococcal disease, pneumonia being its most common form affecting adults.

A possible threat: 

As per reports most Indian vaccines manufacturers get a major chunk of their sales revenue from exports to UN agencies, charitable organizations like, the Bill & Melinda Gates Foundation and GAVI, and other country-specific immunization programs.

The report predicts, the virtual monopoly that Indian vaccines manufacturers have enjoyed in these areas, will now be challenged by China, as for the first time, in 2012, the Chinese national regulatory authority received World Health Organization’s (WHO) ‘pre-qualification’ certification that allows it to approve locally manufactured vaccines to compete for UN tenders. 

Action areas to drive growth:

McKinsey in its above report ‘India Pharma 2020’ indicated that the action in the following 4 areas by the vaccine players would drive the vaccine market growth in India:

  • Companies need to go for local production of vaccines or leverage supply partnerships. MSD and GlaxoSmithKline’s local partnership in India and for the HiB vaccine with Bio-manguinhos in Brazil may be cited as examples.
  • Companies will need to conduct studies on the economic impact of vaccination and establish vaccine safety and performance standards.
  • Extension of vaccine coverage beyond pediatricians and inclusion of general practitioners, consulting physicians and gynecologists will be essential.
  • Companies will need to enhance supply chain reliability and reduce costs.

Conclusion: 

On January 7, 2012, while requesting the ‘Overseas Indian Medical Professionals’ to partner with the institutions in India, the Health Minister, in his address, announced that the Ministry of Health has already introduced the second dose of measles vaccine and Hepatitis-B vaccination across the country. Moreover, from December 2011 a ‘Pentavalent Vaccine’ has been introduced, initially in 2 States, covering 1.5 million children of India.

All these augur quite well for the country. However, keeping in view of the humongous disease burden of India, immunization program with various types of vaccines should receive active encouragement from the government as disease prevention initiatives, keeping the future generation in mind.

If vaccine related pragmatic policy measures, with equal focus on their effective implementation, are initiated in the country, without delay, the domestic vaccine market, in turn, will receive much awaited further growth momentum. Such initiatives together with newer foreign players and modern imported vaccines coming in, would help the country addressing effectively a prime healthcare concern of the country in a holistic way.

It is about time to aggressively garner adequate resources to develop more modern vaccines in the country, promote and implement vaccine awareness campaigns in the nation’s endeavor for disease prevention before they strike hard and at times fatally.

That said, taking available real world facts into account, doesn’t Dr. Gerhard Buchwald’s and today’s anti-vaccination lobbyists’ postulation, ‘Vaccination – A Business based on fear’, appear to be emanating from a self created world of doom and gloom, defying public health interest for effective disease prevention?

Tracking MDG 6 in India – not a mean achievement to combat the dreaded disease

At the turn of the new millennium, in 2000, 189 nations of the world under the banner of United Nations Development Program took a pledge to free people from extreme poverty and multiple deprivations.

This global pledge for humanity on eight key areas was termed as the ‘Millennium Development Goals (MDG)’, which the global community should achieve by 2015. Again in September 2010, the world reiterated its pledge to hasten progress towards achieving these goals within the same pre-scheduled time period.

Combating HIV/AIDS is the sixth of the eight MDGs that India, along with other 188 nations, is expected to achieve by 2015.

Looking Back:

Way back in late 1986, the first incidence HIV in India was diagnosed among the sex workers in Chennai. The origin of the infection was reported to be from the foreign visitors.

The National AIDS Control Organization (NACO) was constituted in the following year and by end 1987, around 135 persons were diagnosed as HIV positive and 14 were suffering from AIDS. Almost around the same time, a rapid spread of HIV was reported from within the ‘Injecting Drug Users (IDU)’ in Manipur, Mizoram and Nagaland. Incidentally, all these states have a common border with Myanmar.

According to the first joint survey conducted by UNAIDS and NACO in 2007, the number of people living with HIV in India was estimated between 2 million and 3.1 million. In 2009 this estimated number declined to 2.4 million.

As per the Government of India (March 1, 2011), there has been an overall reduction in adult HIV prevalence and HIV incidence (new infections) in the country. The estimated number of new annual HIV infections has declined by more than 50% over the last decade, from estimated 2.7 lakhs in 2000 to approximately 1.2 lakhs in 2009. Adult HIV prevalence at national level has declined from 0.41% in 2000 to 0.31% in 2009, although variations exist across the states.

Some actionable areas:

As reported by the National Aids Control Organization (NACO), ‘Injecting Drug Use (IDU)’ and sexual intercourse through homosexual route by some section of the male population have still remained the routes of transmission of HIV in different parts of India, which need to be addressed with a much greater detail.

In the North Eastern States, besides IDU, HIV prevalence among the Female Sex Workers (FSW) is increasing. This suggests a two-prong spread of the pandemic infection in the country.

Moreover, HIV prevalence within the women attending Ante Natal Clinics (ANCs) in North Indian states also needs to be addressed with utmost care.

HIV/AIDS and Drug Prices:

Pricing of HIV/AIDS drugs are globally a very sensitive issue. Currently, because of the availability of many generic drugs, intense competition between them and direct price negotiation for newer brands, there has been a declining price trend for many HIV/AIDS medicines in the developing countries, like India.

This situation has enabled about 5.25 million HIV positive persons from the developing countries to undergo treatment for the acquired infection.

In India, people living with HIV/AIDS have access to Anti-retroviral (ART) drugs, free of cost, through 292 ART Therapy centers and 550 Link ART Centers spread across the country.

As per the Ministry of Health (February 22, 2011), there is no gap between demand and supply of drugs for the HIV/AIDS patients in the country. About 3, 87,205 patients are on ART therapy through the above centers (2010).

Recently product patents for two key HIV/AIDS medicines namely, Lopinavir/Ritonavir and Atazanavir bisulphate were not granted by the Indian Patent Office giving reasons of ‘lacked inventive ingenuity’. Though, this is a patent law related legal issue, it has been hyped up as a ‘major victory for public health and access to affordable treatment’.

I hasten to add, despite this situation, all drugs used for the treatment of HIV/ AIDS are still not available at an affordable price to the poor, across the world.

Funding for HIV/AIDS treatment in India:

The Finance Minister of India in his Union Budget proposal for 2011-12 allocated a sum of Rs. 1700 Crore (around US$ 380 million ) as against an outlay of Rs.1435 Crore (around US$ 320 million) in 2010-11 for the treatment of HIV/AIDS.

Market Size of HIV/AIDS Drugs:

Current market size of HIV drugs is around Rs. 151 Crores  (around US$ 36 million) growing at 11% over the previous year. As per reported data, around 10 HIV drugs are now being marketed in India with 162 different brand names by over 30 companies including, Cipla, FDC, Torrent, Hetero, Sun Pharma, Lupin, Ranbaxy, Zydus Cadila, Natco, Alkem and GSK.

Globally Gilead, Abbott, Pfizer, GlaxoSmithKline, Merck and BMS are among the key manufacturers of HIV drugs.

The world market size for HIV Drugs is estimated to exceed US $15.5 billion by 2015. The key growth driver is still increasing disease prevalence in some countries of the world. Treatment of HIV/AIDS with cheaper Anti-retroviral (ART) drugs has transformed the treatment of this dreaded disease into a manageable proportion.

Unique initiative of UNITAIDS:

For diseases like HIV/AIDS, one school of thought leaders feel that the way forward to resolve such pricing issue is by putting in place an alternative system of ‘remuneration and reward’ to further R&D initiatives in the key areas of public health interest, globally.

Towards this direction, in 2009 UNITAID, an international institution against AIDS, TB and malaria, proposed the ‘Patent Pools’ concept. This system of ‘pool’ will hold licenses on various patented HIV/AIDS drugs, which the generic manufacturers will be allowed to produce at a much lesser price for the least developing countries of the world.

National Institute of Health (NIH) of USA has now become the first patent holder to license a HIV/AIDS drug Darunavir to the patent pool. It appears, the ‘Patent Pool’ initiative to be successful, voluntary participation of larger global pharmaceutical companies is absolutely critical, though many innovator companies may not find any significant commercial benefit within this system.

Will HIV Vaccine be the ultimate answer?

Still with so many newly infected people with HIV every day in various corners of the world, a suitable vaccine to prevent the infection would indeed be indispensable to effectively control this disease. An affordable HIV vaccine could thus be an appropriate answer to fight against HIV/AIDS across the world.

Early In March 2011, the International AIDS Vaccine Initiative (IAVI) and the Translational Health Sciences and Technology Institute (THSTI), of the Department of Biotechnology, Government of India announced together to fund an HIV vaccine design program in India. This HIV vaccine initiative is estimated to cost around Rs.50 Crore (around US$ 12 million) over a five year period.

Recent Developments:

Early this year, UNAIDS/WHO/UNDP launched a new policy brief urging countries to use IP flexibilities under the TRIPS Agreement.

The brief includes flexibilities like, compulsory licensing, parallel imports exemption of ‘Bolar Provision’ and highlights the success achieved in reducing prices in Brazil through the threat of compulsory licensing. The brief also highlights India’s 3(d) provision.

Conclusion:

In India, although the overall progress of MDG initiatives is not satisfactory just yet, ongoing intense efforts to control and treat HIV/AIDS seem to be paying good dividends.

It is interesting to note, UNAIDS ‘Outlook Report 2010’ highlights, “Up to 80% of the cost of treatment isn’t for the medication but for the systems to get it to a person and to keep him or her on it. Globally, only one third of people who need treatment are on it.” I reckon, the situation is no different in India.

Pragmatic intervention of all the states for Preventive Healthcare could significantly reduce the burden of disease of ‘We, the People of India’.

Overall disease pattern in India is showing a perceptible shift from the age old ‘Infectious Diseases’ to ‘Non-infectious Chronic Illnesses’. As reported by IMS, incidence of chronic ailments in India has increased from 23% in 2005 to 26% in 2009.

It is estimated that chronic illnesses will be the leading cause of both morbidity and mortality by the next decade in the country, significantly increasing the burden of disease across the socio-economic strata of the nation. It goes without saying that poor people will be hit harder, if corrective actions are not undertaken right now.

As a consequence of such changing disease pattern, healthcare needs and related systems of the country should undergo a paradigm shift together with the emergence of a carefully planned concept of ‘Preventive Healthcare’ for the entire population of the nation.

It is a myth that non-infectious illnesses are more prevalent in higher socio-economic strata:

There is a common perception that Non-Communicable Diseases (NCDs) are more prevalent within higher socio-economic strata of the society. However, a national survey done in India shows that diseases related to misuse of alcohol and tobacco are higher in the poorest 20 percent quintile of our society.

However, a research recently study done in 1600 villages, spanning across 18 states of India and published on the September 27, 2010 edition of the British Medical Journal (BMJ), reported that the risk-factors of non-communicable diseases are high in rural India, which is the home of over 70% of the population of India. (Non-communicable Disease Risk Factors High in Rural India.

As this population has limited access and affordability to healthcare in general, the situation demands greater importance and focus.

Risk-factors of NCDs in rural India:

The above BMJ study highlighted prevalence of the following key risk-factors for the vulnerable population:

• Tobacco use (40% men, 4% women)
• Low fruit and vegetable intake (69% men, 75% women)
• Obesity (19% men, 28% women)
• High cholesterol (33% men, 35% women)
• Hypertension (20% men, 22% women)
• Diabetes (6% men, 5% women)
• Underweight (21% men, 18% women)

Current healthcare system in India:

Currently with appropriate disease treatment measures, alleviation of acute symptoms of the disease that a particular patient is suffering from, is the key concern of all concerned, starting from the doctors to the patients including their families. The process of the medical intervention revolves round treatment protocols and procedures based on the diagnosis of the current ailments and not so much on preventive measures for other underlying diseases, except with the use of vaccines for some specific diseases.

Developing a protocol for ‘Preventive Healthcare’ for non-communicable diseases is very important:

In the above process, while addressing the acute problems of the patients’ current ailments is very important, proper risk assessment of other underlying diseases, if any, which the patient could suffer from in future, for various reasons, do not attract any organized attention. As a result the important advice on preventive healthcare from the doctors, properly highlighting its importance, is not available to most of the patients to enable them to significantly reduce, if not eliminate, their future burden of disease.

Keeping such common practices in view and noting that ‘Preventive Healthcare’ is significantly different from ‘Curative Healthcare’, developing an appropriate protocol for ‘Preventive Healthcare’ has become a crying need of the hour.

‘Preventive Healthcare’ in India should attract high priority of the healthcare policy makers with a careful vigil on its effective implementation at the ground level:

All said and done, the ‘Preventive Healthcare’ system in India is in its very nascent stage. If appropriate measures are taken in this area, like learning to reduce the impact of mental and physical stress, avoiding sedentary life style, taking healthy diet, avoidance of tobacco and alcohol consumption, leading healthy sex life etc., it can in turn immensely help the population to remain disease free and healthy, thereby contributing to improvement of their respective work productivity in a very substantial way.

Recently re-structured Medical Council of India should also step in:

Thus the role of medical professionals in the disease prevention process is also very important. The interaction of the patients with the doctors when they meet to address any ailment provides huge opportunity to the doctors to advise those patients about various measures of underlying disease prevention, for which different patients have different types of exposures.

Keeping all these points in view, through regulatory initiatives, the newly restructured Medical Council of India (MCI) should consider making ‘Preventive Healthcare’ an integral part of each interaction of a patient with a doctor.

Include the civil society in the preventive healthcare initiatives:

The risk factors of many of the diseases like, cancer, chronic respiratory disorders, cardiovascular, diabetes, and hypertension can be identified well in advance and appropriately assessed. Therefore, such diseases can be prevented effectively, to a great extent, provided the healthcare policy of the country supports the ‘Disease Prevention’ process, program and initiatives through adequate resource allocation, improving awareness of the civil society and above all including them in this healthcare improvement process of the nation.

Need to raise general awareness towards ‘Preventive Healthcare’:

Raising the level of awareness of ‘Preventive Healthcare’ is indeed very important. It requires a change in the mindset of the community in general, together with the healthcare policy makers, medical profession, employers, patients and their families.

National Non-Communicable Disease (NCD) prevention program of the government:

As per the planning commission, the government of India has initiated the following structured measures for the prevention of NCD:

• “Health education for primary and secondary prevention of NCDs through mobilizing community action;
• Development of treatment protocols for education and training of physicians in the prevention and management of NCDs:
• Strengthening/creation of facilities for the diagnosis and treatment of CVD and stroke, and the establishment of referral linkages;
• Promotion of the production of affordable drugs to combat diabetes, hypertension, and myocardial infarction;
• Development and support of institutions for the rehabilitation of people with disabilities;
• Research support for: Multispectral population-based interventions to reduce risk factors;
• The role of nutrition and lifestyle-related factors;
• The development of cost effective interventions at each level of care”.

Conclusion:

Many diseases in India, with proper ‘Disease Prevention’ measures can be effectively averted. It is worth repeating that some common measures which can be easily practiced through community initiatives are maintenance of proper hygiene, sanitation, adequate physical activities, moderation in alcohol and tobacco consumption, healthy sexual activities, avoidance of unhealthy food etc.

All the state governments of India through Public Private Partnership (PPP) initiatives with all stakeholders, including the pharmaceutical industry and the civil society, should make the movement of ‘Preventive healthcare’ self-sustainable across the nation. Health being a state subject in India, the role and initiatives of the respective state governments towards this important initiative will be the key determinant of success or failure.

Such a movement, at the same time, needs to be strengthened by appropriate government policy measures and regulations wherever necessary. Pan India roll out of innovative disease awareness campaigns in tandem, highlighting sustainable and effective disease prevention processes will help reducing longer term healthcare cost significantly, thereby translating the well-known dictum into reality, ‘Prevention is better than cure’.
