The object of the study was the content of IgG autoantibodies (AAB) to S-100В protein in blood serum in children and teenagers with Diabetes Mellitus Type I. The study involved 76 patients of both sexes aged 1 to 17 years, including 38 children with Type I Diabetes (Group I) and 38 children without diabetes (Group II). It was found that the maximum levels of AAB to S-100В protein were observed in severe cases of Type I Diabetes (Group I). These cases also demonstrated higher levels of glucose: 12.45±1.98 mmol/l and ketone bodies in the urine (160 mg/dl). During the examination, clinical evidence of diabetic ketoacidosis and cerebral edema were observed. In group II, the content of AAB to S-100В protein was within normal range. It is assumed that higher content of AAB to the S-100В protein may be a predictor of children’s brain dysfunction related to long-term Type I Diabetes Mellitus.
