[An analysis of the interrelationship of the HLA genotype and carbohydrate metabolism in the families of probands with insulin-dependent diabetes mellitus].
A total of 15 families were investigated: probands with insulin-dependent diabetes mellitus and their relatives of the 1st degree of progeny (43 persons) in order to study the distribution of HLA antigens and their interrelationship with the gravity of a course of diabetes mellitus and the type of GTT. Antigens DR3 and/or DR4 were revealed in 93% of probands, especially in heterozygous patients (57.1%). A low level of C-peptide (0.21 +/- 0.03 ng/ml) was noted in most of the probands excluding 3 patients with nephropathy. Distinct relationship of antigens DR3 and DR4 with a clinical course of disease and its severity was undetectable. Antigens DR3 or/and DR4 were detected in 96% of the relatives with the prevalence of antigen DR4 (in 54.2%). During GTT normal tolerance was observed in 82.1% (23 persons), disorders were noted in 4, insulin-dependent diabetes mellitus--in one. Most of the relatives (82.6%) with normal glucose tolerance had antigens DR3 and/or DR4. Irrespective of the type of DR antigens the probands' relatives were characterized by moderate hyperinsulinism (by the results of IRI and C-peptide of blood serum).
