Islet transplantation, blood sugar and type 1 diabetes

New clinical trial results show that transplantation of pancreatic islets--cell clusters that contain insulin-producing cells--prevents severe, potentially life-threatening drops in blood sugar in people with type 1 diabetes. Researchers found that the treatment was effective for people who experienced episodes of severe hypoglycemia--low blood sugar levels that can lead to seizures, loss of consciousness and death--despite receiving expert care.

The Phase 3 trial was funded by the National Institute of Allergy and Infectious Diseases (NIAID) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), both part of the National Institutes of Health, and was conducted by the NIH-sponsored Clinical Islet Transplantation (CIT) Consortium. The investigators designed the study in consultation with the U.S. Food and Drug Administration to enable potential future licensure of the manufacture of purified human pancreatic islets. The results appear online today in Diabetes Care.

"The findings suggest that for people who continue to have life-altering severe hypoglycemia despite optimal medical management, islet transplantation offers a potentially lifesaving treatment that in the majority of cases eliminates severe hypoglycemic events while conferring excellent control of blood sugar," said NIAID Director Anthony S. Fauci, M.D.

Pancreatic cell transplantation: a breakthrough for type 1 diabetes?

The results of a phase 3 clinical trial are being hailed as a "breakthrough" in the treatment of type 1 diabetes, after finding that transplantation of islet cells - clusters of cells in the pancreas that contain insulin-producing cells - prevented potentially life-threatening reductions in blood sugar among patients with the disease.

Study co-author Dr. Xunrong Luo, associate professor of medicine and surgery at Northwestern University Feinberg School of Medicine in Chicago, IL, says the findings show that islet cell transplantation is a viable treatment option for type 1 diabetes patients who have severely low blood glucose levels, or hypoglycemia.

What is more, the team says the findings suggest islet cell transplantation could eliminate the need for lifelong insulin therapy for people with type 1 diabetes.

The researchers recently published their results in Diabetes Care - a journal of the American Diabetes Association.

Type 1 diabetes accounts for around 5% of all diabetes cases in the US. It occurs when beta cells within the islets of the pancreas are unable to produce insulin - the hormone that regulates blood glucose levels by promoting transportation of glucose from the bloodstream to other cells, where it is used for energy.
