BACKGROUND
It has been suggested that the clinical and immunological characteristics of diabetes mellitus in Koreans are different from those of Caucasians. This study was undertaken to investigate the prevalence of autoimmune markers in Korean adults with IDDM and recent-onset NIDDM. METHODS: Seventy-seven Korean adults with IDDM and 245 recently(within 2 years) diagnosed NIDDM were included in the study. Islet cell cytoplasmic antibody was measured by immunohistochemical method, and anti-glutamic acid decarboxylase (anti-GAD) antibody was measured by radioimmunoassay. RESULTS: 1) The prevalence of ICA, anti-GAD antibody positivity was 27% and 40% in IDDM patients, and 5% and 4% in recent-onset NIDDM patients, respectively. 2) The prevalence of ICA positivity in IDDM patients decreased from 42% within one year to 21% over one year after clinical onset of disease. On the other hand, the positivity of anti-GAD antibody did not change according to the duration of diabetes. 3) The prevalence of ICA tends to be lower in IDDW patients with low serum C-peptide concentrations. In contrast, the prevalence of anti-GAD antibody was not different according to sernm C-peptide levels. CONCLUSION: These results suggested that the prevalence of ICA and antii-GAD antibody was lower in Korean adult IDDM and recent-onset NIDDM patients than that in Caucasians.
