Prevalence of ICA-12 and Other Autoantibodies in North Indian Patients with Early-Onset Diabetes
This study attempts to assess the prevalence of various autoantibodies in early-onset diabetics in northern India, with emphasis on antibodies against glutamic acid decarboxylase (GAD65), IA-2, ICA-12, 21-hydroxylase (21-OH), and tissue transglutaminase (TTG). GAD65 and IA-2 antibodies were found to be present in approximately 26% of cases of type 1 diabetes. A subset of patients clinically diagnosed to have MMDM appears to have an autoimmune etiology, with more than 20% showing serpositivity for IA-2 antibodies. Antibodies against ICA-12 were prevalent in both type 1 diabetes and MMDM. Approximately one of seven patients with type 1 diabetes showed erological evidence of celiac disease.
