In what promises to be a boon for treatment of certain types of diabetes, encouraging results were obtained in pancreatic islet transplantation in simians by researchers from a city hospital, who are all set to try it out in humans on Friday.
Beta cells in pancreas produce insulin to control blood sugar levels. However, due to hereditary, environmental or other causes these cells stop producing insulin in some people forcing them to depend on artificial insulin.
With about 285 million people afflicted with diabetes worldwide, including 62.4 million in India, pancreatic islet transplantation was emerging as an important option in the treatment of type-1 and type-3C diabetes. Islet cell transplantation involving injection of the isolated islet cells into liver was being offered in a few specialised centres in the USA and Europe. However, patients would be required to take immuno-suppressants.
But doctors at the Asian Institute of Gastroenterology have developed a method to transplant islet cells through an encapsulated device without using immuno-suppressants.
Addressing a press conference on the eve of a two-day Indo-US Bilateral Workshop on ‘Pancreatic Islets: From isolation to Transplantation’, chairman of the Asian Institute of Gastroenterology (AIG), K. Nageshwar Reddy said that scientists from AIG’s research wing in collaboration with National Institute of Nutrition (NIN) have isolated, cultured and transplanted pancreatic islets in simian models through an immuno-isolation device, doing away with the need to use immuno-suppressants.
A year after transplantation, it was surprisingly found that the isolated cells were not only active, but proliferated. Called ‘theracyte’, the device, a kind of an “artificial pancreas” containing lakhs of islet cells would be inserted under the skin.
The tiny porous gaps in the capsule would not allow the cells to move but allow transmission of insulin into the body and energy into the cells.
