The aim of our study was to investigate insulin sensitivity and beta cell function in hemodialysis (HD) patients without diabetes. We hypothesized that parathyroid gland function was a determinant of insulin sensitivity and/or beta cell function. The study was a randomized, cross-sectional one and patients were divided into two groups (total 27 patients), Gp.1 being those with relative hypoparathyroidism (iPTH<200 pg/ml) – 9 (33.3%), Gp.2 those with hyperparathyroidism (iPTH≥200 pg/ml) – 18 (66.6%) with Gp.3 (consisting of 4
