Trimester Sequential Estimation of Serum Zonulin as a Predictor of Gestational Diabetes Mellitus

Trimester Sequential Estimation of Serum Zonulin Overrides Glucose Homeostasis Biomarkers for Prediction of Gestational Diabetes Mellitus

Gestational diabetes mellitus (GDM) is the development of glucose intolerance (GI) during pregnancy in a previously normoglycemic (NG) woman and associated with insulin resistance (IR). GDM is the most prevalent metabolic disorder during pregnancy and became a major public health problem for being usually diagnosed and detected after 24 gestational weeks (GW), while its complications can occur much earlier and this may explain its burden on maternal and fetal welfare. Human zonulin is a surrogate marker of intestinal permeability and can be utilized as biomarker for intestinal barrier function. Zonulin-mediated increase in intestinal permeability plays a role in the pathogenesis of insulin resistance, obesity, DM and metabolic syndrome. The increasing global prevalence of GDM with its associated risk of poor pregnancy and long-term risks for the mother and the offspring may lead to the production of new generation of diabetics.
