Detailed Description | The metabolic control in type 2 diabetes mellitus can be measured by means of glycosylated hemoglobin. A low value glycosylated hemoglobin indicates a good metabolic control, and has been shown to be associated with a better prognosis regarding diabetic complications. Type 2 diabetes is a disease with a profound genetic component. Peroxisome proliferator-activated receptor gamma is a transcription factor implicated in adipocyte differentiation, lipid and glucose metabolism. Peroxisome proliferator-activated receptor alfa is a transcription factor implicated in lipid oxidation and gluconeogenesis and is present in liver, kidney, heart, skeletal muscle and adipose tissue. Pioglitazone is a thiazolidinedione that targets nuclear peroxisomal proliferator activated receptors, members of the super family of ligand activated transcription factors. Specifically, thiazolidinediones bind to the peroxisome proliferator-activated receptor gamma and affect transcription factors that influence expression of genes responsible for the production of proteins important in carbohydrate and lipoprotein metabolism. These include increases in glucose transporters 1 and 4 resulting in enhanced peripheral glucose utilization by fat and skeletal muscle. This is a pharmacoepidemiological study to evaluate whether the individual genotype of the patients have any influence on the efficacy of pioglitazone. |
