RESUMO
OBJECTIVE: The aim of this study is to compare galanin and IL-6 levels in pregnant women with gestational diabetes mellitus (GDM) and normal glucose tolerance (NGT). Also association of insulin resistance markers, galanin and IL-6 was investigated. MATERIALS AND METHODS: The study registered 30 pregnant women with GDM and 30 pregnant women with NGT. Fasting venous blood samples were collected from all patients. Galanin and IL-6 levels were measured by an enzyme-linked immunosorbent assay. RESULTS: Galanin and IL-6 levels were found higher in pregnant women with GDM (p < 0.001). A significant positive correlation was determined between galanin concentrations and glucose (r = 0.240, p = 0.065), insulin (r = 0.681, p < 0.001), HbA1c (r = -0.644, p < 0.001), IL-6 (r = 0.783, p < 0.05) and oral glucose challenge test results (r = 0.745, p < 0.001) in pregnant women included in study, whereas no significant association was determined between galanin and gestational age (r = 0.058, p = 0.662), body mass index (r = -0.019, p = 0.886). CONCLUSION: Galanin and IL-6 were found to be significantly associated with insulin resistance markers in GDM, thus may play important roles in regulation of glucose hemostasis.
