AimTo study the frequency of islet antibodies in a large cohort of clinic- and community-based patients with Type 2 diabetes in northern India. MethodsWe measured glutamic acid decarboxylase (GAD) antibodies in 618 adults with Type 2 diabetes (378 patients with diabetes attending a hospital clinic, 240 patients diagnosed in a community survey) and in 192 healthy subjects residing in north India. Islet antigen2 (IA2) antibodies were also studied in a proportion of the patients with diabetes (n=492) and in a control population (n=191). GAD and IA2 antibodies were measured by immunoprecipitation of the respective S-35-labelled recombinant antigen. ResultsWe found that GAD antibodies were present in nine (1.5%) patients with diabetes (clinic population: 0.8%, community study: 2.5%), a prevalence similar to that among the subjects without diabetes (n=2; 1%). IA2 antibodies were detected in seven patients with Type 2 diabetes (1.4%) and in two healthy control subjects (1.0%). The frequency of either GAD or IA2 antibodies was similar in people with and without diabetes (3.2 vs 2.1%). No subject was found to have both antibodies. Insulin requirement was higher among antibody-positive than among antibody-negative patients (GAD antibody: 33 vs 6.3%; P=0.001; GAD or IA2 antibody: 23.1 vs 6.4%; P=0.02); however, other clinical features were similar in the two groups. ConclusionsIn the present north-Indian population with Type 2 diabetes, the overall prevalence of GAD antibodies and the prevalence of either GAD or IA2 antibodies were considerably lower than those reported in white European populations.
