Abstract
AIM: To explore the relationship between islet function and bone mineral density in first-degree relatives of type 2 diabetes mellitus (T2DM) patients.
METHODS: In first-degree relatives of T2DM patients, 30 cases with normal glucose tolerance (NGT) [NGT (+) group] and 30 cases with impaired glucose tolerance (IGT) [IGT (+) group] were included in the study. Thirty healthy controls without family history of T2DM [NGT (-) group] were also included. Electrochemical luminescence immunoassay was used to test fasting insulin level and insulin level at 2 h after oral administration of 75 g anhydrous glucose powder. Lumbar spine and left femur bone mineral density was determined by X-ray absorptiometry.
RESULTS: The homeostasis model assessment-pancreatic beta-cell function (HOMA-beta) was significantly lower in the NGT (-) group than in the NGT (+) group and IGT (+) group, but showed no statistical difference between the NGT (+) group and IGT (+) group. Compared with the IGT (+) group and NGT (+) group, bone density of L2 to L4 (L2-L4), the femoral neck and femoral trochanter was significantly different in the NGT (-) group, although there was no statistical difference between NGT (+) group and NGT (-) group.
CONCLUSION: All T2DM first-degree relatives, regardless of whether they have NGT or IGT, have decreased islet function, and T2DM first-degree relatives with IGT have decreased bone mineral density in the lumbar spine and femoral both.
