title: Studies on the association of NIDDM in Japanese patients with hyperthyroid Graves' disease.
abstract: We attempted to analyze the association of hyperthyroid Graves' disease with non-insulin-dependent diabetes mellitus (NIDDM). Forty-nine patients (23 males and 26 females; 7.6%) of a total of 647 patients with hyperthyroid Graves' disease had NIDDM, several years before or after Graves' disease was diagnosed. Only 1 patient had insulin-dependent diabetes mellitus. Compared with the general Japanese population (n = 9,133), the incidence of NIDDM (n = 348; 3.9%) in patients with Graves' disease was higher in all age groups. Only 4 patients (8.2%) of the 49 hyperthyroid patients with NIDDM had a history of being overweight (body mass index > 25). In contrast, 276 (79.9%) of the 348 diabetic patients were currently or previously overweight. Moreover, the incidence of a family history of diabetes (13 of the 49 hyperthyroid Graves' patients with NIDDM; 26.5%) was also lower in the patients with NIDDM in the general Japanese population (50% incidence). The male:female ration in patients with Graves' disease and NIDDM was 1:1.1; much different from that in the total Graves' disease population (1:4.1). Analysis of the HLA loci A, B, C, DR and DQ (35 determinations) in 35 hyperthyroid patients with NIDDM and in 386 subjects from the general population revealed a highly significant difference between them in the incidence of HLA-Cw4, -DR2, -DQw1, -DQw3 and -DQw4. This study suggests that there was an association of Graves' disease with NIDDM. A significant association of HLA-DR and -DQ loci was observed in hyperthyroid Graves' patients with NIDDM.
