Randomized Clinical Trial, Effect of Metformin and Rosiglitazone Over Glucose Homeoastasis in no Diabetic With Metabolic Syndrome Patients.

Metabolic syndrome is a risk factor for diabetes mellitus characterized by insulin resistance, hypertension, triglyceride elevation, low levels of high-density lipoproteins, and obesity. Metformin and rosiglitazone are two insulinosensensitizers used in the treatment of diabetes. Now there is controversy over the use of insulinossensitizers in non-diabetic patients with metabolic syndrome. To compare the effect of insulin sensitizing drugs (metformin and rosiglitazone) over glucose homeostasis (GH) in no diabetic metabolic syndrome individuals. Randomized blinded clinical trial in patients with metabolic syndrome without diabetes was done, sample size (n=30). Prior to detailed information and signature of informed consent by patients was randomized forming three treatment groups, a) Placebo, b) Metformin (850 mg/day), c) Rosiglitazone (4 mg/day), treatment was administered for 8 weeks. GH was measured before and after treatment using oral glucose tolerance test (OGTT), and IR-index (Homeostatic Model). Determination was performed on weight, size, body mass index, plicometry, blood pressure, fasting glucose levels, triglycerides, HDL-cholesterol and insulin. Statistic no parametric (Kruskal Wallis, Wilcoxon, U Mann Whitney) to compare characteristics inter o intra groups was done. Exact Fisher test was used for qualitative variable, and consider significance with p<0.05.
