Abstract
Objective To investigate diabetes-specific autoantibodies and additional autoimmune phenomena in a very large cohort of young patients with type 1 diabetes (T1D).
Research Design and methods Data from 28,671 patients < 30 years with T1D from 242 specialized centres in Germany and Austria were analyzed.
Results At least one Beta-cell-antibody was present in 81.6% of patients. ß-cell-Ab-negative patients were significantly younger at diabetes onset (p<0.0001). 19.6% had positive thyroid antibodies with female predominance (62 %, p<0.0001). Antibodies to tissue transglutaminase were present in 10.7%, with a significantly longer duration of diabetes (p<0.0001). Parietal cell antibodies were found in 283 patients, associated with older age (p<0.001), and adrenal antibodies were present in 94 patients. In 575 patients, at least 3 different autoimmune phenomena were present.
Conclusions Thyroid autoimmunity and antibodies suggestive for celiac disease are the most prevalent additional immune phenomena in T1D. Parietal/ adrenal antibodies are rare.
