Progression of Autoimmune Diabetes
Autoimmune diabetes is due to destruction of insulin-secreting beta islet cells by an immune-mediated process, which is induced and promoted by the interaction of genetic and environmental factors.This form of diabetes is one of a group of autoimmune diseases that affect about 10% of the population in the developed world.The detection of diabetes-associated autoantibodies, including glutamic acid decarboxylase antibodies (GADA), islet cell antibodies (ICA), and insulinoma-associated (IA-2) autoantibodies is widely held to reflect an underlying autoimmune pathology but the clinical features associated with the presence of these diabetes-associated autoantibodies is highly variable ranging from lack of symptoms with normal glucose tolerance to catastrophic and potentially fatal diabetic ketoacidosis. It is the purpose of this article to establish the range of metabolic features associated with diabetes-associated autoimmune changes and discuss how this metabolic spectrum itself reflects a spectrum of immune and clinical changes that cast light on the nature of autoimmune diabetes
