Sheetal Shetty was in the Intensive Care Unit (ICU) of the Powai-based Hirandani Hospital where she was admitted for a liver tumour. When the treating doctors told her younger brother Raj to procure human albumin - a protein found in blood plasma and which is produced by the liver - he had no idea how tough it would be. A nationwide supply crunch has put human albumin off the shelves since the past few months, resulting in black marketeering and often deaths of patients unable to get hold of it.

Human albumin is used to treat patients suffering from liver ailments, cancer and even burns. Like Shetty, thousands of desperate relatives all over the country are contacting every possible source to lay their hands on something that is getting alarmingly inaccessible.

Raj (40) says he had no idea. "I visited almost every medical shop in the city," he says. "I could not find it anywhere. I finally found a contact who could arrange for imported human albumin manufactured by the US-based company Baxter," Shetty said.

Eventually, Sheetal (42) died on January 6 this year. But, in a testimony of how badly the drug is needed, the four bottles that remained unused were picked up by relatives of other patients within an hour.

Passing the buck
Despite the urgency of the problem, the discussion surrounding it mostly seems to be a blame game between the stakeholders in the human albumin industry. To see how difficult it is to procure the protein, mid-day called several chemists and hospital pharmacies in the city and received the same response - not available.

There is no record of the total albumin collection in India, as it is only one of the byproducts extracted from human plasma. Moreover, there is no system to track the demand and supply of human albumin.

A pharmacist at Bombay Hospital, one of the city's major healthcare centres, told mid-day that they do not have human albumin in their stock for over three months. "On average, we get five or six enquiries a day from Mumbai as well as Rajasthan and Gujarat," he said. "But we are helpless. We depend on wholesale stockists who themselves do not receive regular supply."

Once easily available, the protein's short supply now could be an unforeseen effect of the government's move to control its price due to lower profit margins, a Mumbai drug stockist revealed. "The shortage has been felt since the NPPA (National Pharmaceutical Pricing Authority) imposed price restrictions on the drug in September 2014. The drug was earlier being sold for R5,200, while the current price is R3,849 (20% concentration in 100 ml vial) . This has made it unviable to import the drug."

In India, any human blood element like RBCs, platelets, plasma, or human albumin are treated as drugs, and they can be brought under price control as they are categorised as essential drugs. However in case of human albumin, which is mostly imported into India, the price cap meant it made no business sense for wholesalers and retailers.

When pressed for answers, Dilip Mehta, president of the Pharmaceuticals Wholesalers Association, Mumbai, blamed monsoon-related ailments like dengue and malaria for the present shortage of human albumin. "Human Albumin was always in short supply in the country, as it is one of the most prescribed drugs because of the safety of usage. And now, apart from patients of liver cirrhosis, burns and cancer, even patients suffering a dip in platelets due to monsoon ailments are demanding human albumin," he said.

"Only two in every 10 patients manage to get the drug today, and the situation will remain the same for the next few months, until some urgent measures are taken at the manufacturer - and the central government - level," Mehta added.

Shockingly, only 25 percent of the demand in the estimated R200 crore market is met. Around 70 percent is either imported as product or imported as frozen plasma and balance 30 percent is manufactured locally by using plasma collected locally.

Wasted resources
While stockists blame the shortage on the pricing change and on the rise of monsoon ailments, others blamed a shortage in blood collection and some others said available blood was being wasted.

In fact, this newspaper had carried a report about the state-run St George Hospital, where 44.5 litres of whole blood and another 917.84 litres of plasma were wasted due to expiration between January 2012 and August 2013 (‘RTI reveals rampant wastage of donated blood', mid-day, November 9, 2013).

S T Patil, Joint Commissioner, FDA, confirmed this. "When we inspected St George's blood bank we found they were indeed wasting the excess blood and plasma," he said. "However, we have taken in writing from St George blood bank that hereafter all their excess blood and plasma will be supplied to other blood banks or hospitals."

Further questions were raised when an RTI activist found discrepancies in the blood collection data. Records obtained under RTI from GT Hospital in the year 2013, showed a total of 955 units of blood had been collected. But records at the Mumbai District Aids Control Society (MDACS) showed that GT hospital had collected only 376 units in the same period.

While the hospital's superintendent, D R Kulkarni was unavailable, the Resident Medical Officer (RMO) Dr Ganesh Doiphode, found that according to the blood bank records, the hospital had collected 955 units of blood in 2013. He explained that the discrepancy in records could have arisen "from a technicality".

The plasma economy
In order to truly understand the inside story to the albumin shortage, it's important to have an overview of the system and economy surrounding its collection and processing.

An estimated 33 million litres of plasma are fractionated every year globally. Fractionation means a segregation of different protein and peptides and other pharmaceutical entities from human plasma used for various therapeutic requirements.

However, most of it is processed and consumed in places such as the US, Europe, Japan, South Korea, etc. India and many of its neighbours are completely dependent on supply from these countries, as they have not evolved their own capability to either source the plasma locally or to manufacture the therapeutic products. This is not only expensive, but is highly undesirable in terms of long-term health security. This situation is also against the World Health Organisation's recommendations on avoiding cross border movement of blood products.

Dr Nabajyoti Choudhury, secretary general of the Asian Association of Transfusion Medicine, New Delhi (a registered body of specialists from 12 Asian countries) said, "In India, we have three plasma fractionation companies, while Iran has one. The rest of the SAARC countries do not have such set ups. The companies send the plasma abroad for fractionation and the extracted products like albumin, immunoglobulin etc are then marketed here, which makes the overheads expensive."

According to him, what the industry really needed was to be given a free rein, much like the dairy industry. This would relieve manufacturers of the restrictions placed on pricing, import and export and other aspects of the drug.

"The government should give a free hand to manufacturers running fractionation centres in the country, supported by a good regulatory framework and minimal control policy, which will help them meet the large demand for such life saving drugs at an economical rate," added Dr Choudhury.

However, Ahmedabad-based pharmaceutical expert Mani Iyer says that the problem goes deeper. Iyer pioneered the development of biological products from recovered human plasma sourced from Indian blood banks, and achieved fractionation of the same through contract fractionation at KGCC (Korea). He is also a member of the Steering Committee set up by the government's Science and Technology department.

Speaking to mid-day from Ahmedabad, Iyer said the persistent shortage of plasma-based therapeutic products in the South Asia region was because of "the low prevalence of the componentization of blood at the blood bank level", which resulted in a lack of quality plasma. This in turn was caused by "low investment in technology towards component preparation, quality standardization and storage".

"This vicious cycle of underinvestment leading to shortage can be addressed by evolving a regional strategy. The issue is best addressed by blood banks, which are the only source of plasma, the basic raw material required for manufacturing of human albumin," Iyer added.

He explained that while blood banks separate plasma from whole blood, they are not equipped to separate albumin from the plasma, leading to 75 per cent of it being wasted. This could become an excellent source for the fractionation industry, as India alone collects around 7 million units of blood yearly and has the potential to generate plasma for fractionation in the range of around 2 to 2.5 million litres yearly.

Finding solutions
Perhaps a resolution to the problem could be on the cards, as the NPPA will soon convene to discuss the pricing and supply problem of human albumin. "We had a meeting with the manufacturers of the human albumin drug to discuss the issue," said A K Khurana, director, pricing and administration, NPPA, New Delhi.

In a couple of months (by March), the National Plasma Fractionation Centre (NPFC) is also expected to begin operations at the new unit at Shatabdi hospital in Govandi, which can handle up to 20,000 litres of plasma for fractionation.

Meawhile, in Ahmedabad, Iyer is currently working on a technological solution to the problem. According to him, the current standard format followed the world over for fractionation facilities is not suitable for India, as they involve a mammoth investment upward of $100 million, much more than individual pharma companies will be willing to put in here.

So, he is currently attempting to develop an end-to-end modular plasma-fractionating platform to process a few thousand litres. This will take care of regional needs and will be capable of maintaining a steady, cost-effective supply. This will be done either directly through blood banks or by developing a commercial understanding with pharma companies. This initiative is supported by the government's department of Science and Technology, the Centre for Bioseparation Technology in Vellore, Chennai as well as a couple of global technology players.
