Incretin hormones and insulin responses during OGTT in newly diagnosed T2DM patients

Several research groups have reported variable results about incretin effects of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1(GLP-1) particularly, as well as cytokines balance in type 2 diabetes mellitus (T2DM). The present case-control prospective interventional study was conducted in 2014-2015 at Medical College for Women & Hospital, Dhaka, investigating responses of incretin hormones and insulin to oral glucose tolerance test (OGTT) in Bangladeshi subjects. Blood samples were collected from 36 OGTT positive adult T2DM patients (Pt) and 30 normal adults (NC) at ‘0’ minute (fasting) and at 2 hours after OGTT. Routine laboratory investigations in blood were done and special parameters in serum, i.e. insulin, HGH, TSH, GIP and GLP-1 were analyzed using enzyme immunoassay kits.
