Background: The purpose of this study was to investigate the occurrence of autoimmune thyroid disease in children and adolescents at onset of type 1 diabetes mellitus (T1DM) and to assess whether the presence of diabetes-specific autoantibodies may predict the autoimmune thyroid disorder.

Methods: Seventy-three children with T1DM were recruited in the study. Glutamic acid decarboxylase antibodies (GADA), Islet cell antibodies (ICA), insulin autoantibodies (IAA), and thyroid antibodies were determined for all patients at the time of diagnosis.

Results: The majority of patients (87.7%) had at least one pancreatic antibody (74.0% for GADA, 20.5% for ICA, and 24.7% for IAA). Thyroid autoantibodies were found in 19 of 73 patients (26.0%) at diagnosis. Thyroid autoimmunity (TA) incidence was not statistically significant by GADA or ICA positivity, but significantly high by IAA positivity (P=0.03) and IAA positivity showed 4.5 odds ratio (95% CI) for TA (P=0.008).

Conclusions: The IAA positivity in children and adolescents with TIDM was found to be strongly related to the positivity of thyroid autoantibodies and thus it could serve as an index for the early prediction of the development of the thyroid autoimmune disorder among children and adolescents with TIDM.
