A new treatment for type 1 diabetes may be in the offing, after results of a preliminary study suggests that an experimental treatment is both safe and effective.
A new treatment for type 1 diabetes may be in the offing, after results of a preliminary study suggests that an experimental treatment is both safe and effective.
Research has shown that GAD (glutamic acid decarboxylase) acts as an autoantigen in people with type 1 diabetes, and is part of the immune system attack on insulin-secreting cells. The hope was that injections of GAD-alum would stop GAD from destroying the insulin-producing cells.
Results of the study of 70 adolescents with type 1 diabetes showed that injections of GAD-alum did help to preserve the insulin-secreting cells of the pancreas. However, the treatment only worked in participants who had been diagnosed within the last six months. The treatment is not a cure, the participants still needed their regular insulin shots, and their insulin secretion still declined throughout the two-and-a-half-year study period, however the decline was not as great in those treated with GAD-alum.
