OBJECTIVE Pioglitazone, a peroxisome proliferator-activated receptor agonist and glipizide, an insulin secretagogue, are commonly used to treat type 2 diabetes. Our study was designed to examine the effects of pioglitazone versus glipizide on body water, body composition, and hemodynamic parameters in the presence of comparable glycemic control between groups. RESEARCH DESIGN AND METHODS We s...

AIMS We assessed the long-term glycaemic effects and the safety profile of triple therapy with the addition of pioglitazone vs. placebo in patients with Type 2 diabetes treated with combined metformin-sulphonylurea therapy in the PROspective pioglitAzone Clinical Trial In macroVascular Events (PROactive). METHODS In a post-hoc analysis, we identified patients treated with metformin plus sulph...

This study was performed to investigate the molecular mechanism and the therapeutic effect of berberine on nonalcoholic fatty liver disease (NAFLD). Rat models were given a high-fat diet (42% kcal) until they developed NAFLD, then were given normal saline (n=10), berberine (n-=10) at 187.5mg/kg/day, or pioglitazone (n=10) at 10.0mg/kg/day intragastrically for 4 weeks, respectively, and evaluate...

Introduction: Impaired glucose tolerance (IGT) often leads to type 2 diabetes (T2DM) and macro vascular disease; and usually associated with insulin resistance. Pioglitazone and metformin are commonly used insulin sensitizers (IS); and can prevent or delay the development T2DM and macro vascular disease. This study was deployed to search the better IS between these two in relation to plasma glu...

BACKGROUND Diabetes is an important global disease, associated with significant morbidity and an increased risk of death due to chronic end-organ complications. The thiazolidinediones, used mainly as third-line agents in type 2 diabetes mellitus (T2DM), have been associated with some safety concerns, such as an increased risk of bladder cancer, an increased risk of bone fracture and heterogeneo...

OBJECTIVE To study the effects of pioglitazone on endothelial dysfunction of subjects with impaired glucose regulation (IGR) among the first-degree relatives of patients with type 2 diabetes mellitus (T2DM). SUBJECTS AND METHODS The first-degree relatives of T2DM patients were screened with oral glucose test and IGR was diagnosed. IGR subjects whose blood glucose was still above the level aft...

The vascular endothelium has a central role in the modulation of vascular tone with associated antioxidant, anti-inflammatory, pro-fibrinolytic, anti-adhesive, and anticoagulant effects. This is primarily accomplished by the timely release of endothelial autacoids. On the other hand, endothelial dysfunction (ED) provoked by insulin resistance has been linked with reduced nitric oxide bioavailab...

BACKGROUND No pharmacologic therapy has conclusively proved to be effective for the treatment of nonalcoholic steatohepatitis, which is characterized by insulin resistance, steatosis, and necroinflammation with or without centrilobular fibrosis. Pioglitazone is a thiazolidinedione that ameliorates insulin resistance and improves glucose and lipid metabolism in type 2 diabetes mellitus. METHOD...

BACKGROUND Recent evidence indicates that insulin resistance in skeletal muscle may be related to reduce mitochondrial number and oxidation capacity. However, it is not known whether increasing mitochondrial number and function improves insulin resistance. In the present study, we investigated the effects of a combination of nutrients on insulin resistance and mitochondrial biogenesis/function ...

BACKGROUND Impaired insulin signalling is increasingly thought to contribute to Alzheimer's disease (AD). The ε4 isoform of the APOE gene is the greatest genetic risk factor for sporadic, late onset AD, and is also associated with risk for type 2 diabetes mellitus (T2DM). Neuropathological studies reported the highest number of AD lesions in brain tissue of ε4 diabetic patients. However other s...
