Abstract

Aim: The present study investigated the effects of growth hormone (GH), insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3) and GH-receptor (GHR)/exon-3 polymorphism on diabetes mellitus (DM) and coronary heart disease (CHD) patients. Patients and Methods: Ninety patients with CHD, 90 patients with DM and 96 controls were included in this study. The GH, IGF-1 and IGFBP-3 serum levels were measured with enzyme-linked immunosorbent assay. GHR/exon-3 variants were determined by multiplex-polymerase chain reaction. Results: The frequency of all alleles and genotypes in all study groups were distributed according to the Hardy-Weinberg equilibrium. In addition, any association between GHR/exon-3 variants and the presence of risk factors were detected. The blood levels of GH, IGF-1 and IGFBP-3 were not distributed according to GHR/exon-3 variants. However, in the DM group, higher levels of IGF-1 and lower levels of GH and IGFBP-3, and in CHD group lower levels of IGF-1, GH and IGFBP-3 were observed. The order of GH levels were DM
