Clinical characteristics and etiological markers in insulin-dependent diabetes associated with an organ-specific autoimmune disease.
Thirty-four insulin-dependent diabetics with a coexistent organ-specific autoimmune disease (Graves' disease, primary myxedema, adrenal insufficiency, generalized vitiligo, primary biliary cirrhosis) were compared to 100 insulin-dependent patients in whom no obvious etiology was detectable. The autoimmune group was characterized by a predominance of females, a family history of autoimmune disease, a later age at onset, better glycemic control, low insulin requirement, persistence of ICA, and greater frequency of HLA B8 but not of B18. However, there was a large overlap between the two groups for all these criteria. In addition, a family history of IDD in first degree relatives and the frequency of serum positive for neutralizing anti-Coxsackie B antibodies were identical in the two groups. These results do not justify the separation of this group of patients as having purely autoimmune diabetes, to the exclusion of other etiological factors, whether genetic or viral.
