title: Glucose-induced insulin response and insulin sensitivity is not related to HLA-type but to age in young siblings of type 1 (insulin-dependent) diabetic patients.
abstract: Glucose-induced insulin response and insulin sensitivity were studied in 32 HLA-identical, 38 haplo-identical and 24 non-identical, islet-cell-antibody-negative, healthy siblings of young Type 1 (insulin-dependent) diabetic patients (age range 10-28 years). No significant differences were obtained between HLA-identical, HLA-haplo-identical siblings and HLA-non-identical siblings in insulin response using an i.v. glucose infusion test even when the insulin sensitivity as estimated by the somatostatin-insulin-glucose infusion test was taken into account. A significant inverse correlation to age was found for both insulin response (r = -0.24, p = 0.02) and insulin sensitivity (r = -0.36, p less than 0.01) in the young siblings studied.
