Brief Summary
The purpose of this study is to asses changes in glycosylated hemoglobin, fasting blood
lipids and genetic polymorphism's in peroxisomal proliferator activated receptors--gamma
receptor after 6 months of pioglitazone, once daily (QD), treatment.
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.
