Nalini Ambady, the first Indian-American woman to teach psychology at three major universities in the U.S., died in 2013 due to leukaemia when she was just 54.

For the medical fraternity in Kerala, her native place, it turned the spotlight on the lack of awareness of stem cell transplant, which could have saved her life.

Four years down the lane, doctors say the situation has changed only marginally, as many patients who require the treatment have not been able to do it because of high expenses, lack of matching donors, and lack of facilities at hospitals.

Doctors note that stem cell transplant is being proposed as an effective treatment for cancers such as leukaemia and lymphoma, and primary immune deficiency disorders. Stem cells do not develop normally in such patients and it affects the blood cells that they make.

By a transplant, the patient gets new stem cells that can make new and healthy blood cells. Earlier, stem cells were collected from the bone-marrow. Now, it is being collected from blood cells.

Neeraj Sidharthan, bone marrow transplant physician at Amrita Institute of Medical Sciences, Kochi, told The Hindu that in Prof. Ambadys case, though matching donors were found, they had all dropped out.

Lack of awareness is still a major issue though there are some positive signs. In some cases, because of lack of infrastructure, cancer cases are not being diagnosed early, and treatment is delayed too, he said.

Ajith Kumar V.T., professor, department of paediatrics, Government Medical College, Manjeri, said donors could not be found often from the same families because of the nuclear family system. There are not many places where you can match the human leukocyte antigen (HLA) typing with donors. Another problem is the lack of stem cell registries in the State from where matching unrelated donors could be found. Even if doctors suggest a stem cell transplant, many families dont opt for it because of the high cost involved. If the donor is from the same family, the cost is relatively low.

But for unrelated donors, it is very high, Dr. Sidharthan said. The solution, Dr. Ajith Kumar said, was government intervention to set up HLA registries and bone marrow transplant centres. nestCare Foundation, a not-for-profit organisation based in the U.S., had recently approached us expressing interest to set up these facilities in the State. Talks are on, he said. Dr. Sidharthan said that in Tamil Nadu, there was a government scheme enabling poor patients to avail themselves of a financial assistance of Rs. 7 lakh for bone-marrow transplant. We need to have similar schemes here too, he added.
