Thyroid antimicrosomal antibodies, gastric parietal cell antibodies (PCA) and antinuclear factors were studied in 208 insulin dependent diabetic (IDD) according to the duration of diabetes and patients age at the time of testing. Antimicrosomal antibodies were found in 11 out of 47 (23.4%) IDD with the duration of less than one year, however this value declined to 13.1% at1to 3 years, 15.3% at 4 to 5 years, 10.8% at 6 to 10 years and 5.8% at more than 10 years. Of the 47 IDD, 7 (14.8%) were positive for gastric parietal cell antibodies. The prevalence of PCA declined with the increasing duration of diabetes.<BR>However, this decrease in the prevalence of antimicrosomal antibodies and PCA was not so extreme as that of pancreatic islet cell antibodies. Antinuclear factors did not reveal a significant correlation with the duration of diabetes.<BR>In normal controls, the prevalence of antimicrosomal antibodies, PCA and the antinuclear factors increased progressively with age. In IDD, the prevalence of the antinuclear factors was also progressively greater with age. However, the prevalence of antimicrosomal antibodies in IDD decreased with age and those of PCA showed the lowest percent in the 40-69 year-age group.
