Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether atorvastatin and fenofibrate are effective in the treatment of lipid disorders in obese, insulin resistant subjects.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Insulin resistance is a heterogeneous metabolic disorder of complex etiology. It underpins dyslipoproteinemia, a key feature of the metabolic syndrome (MetS) that independently predicts cardiovascular disease (CVD). Hypertriglyceridemia, the most consistent lipid disorder in subjects with obesity and type 2 diabetes mellitus, is chiefly a consequence of overproduction and delayed clearance of triglyceride-rich lipoproteins (TRLs). Although the precise mechanisms involved are incompletely understood, experimental and clinical evidence suggests that elevated apolipoprotein (apo) C-III may play a crucial role in the dysregulation of TRL metabolism. investigating the effects of these agents on VLDL-apoC-III kinetics. In this study, we aimed to examine the effect of two lipid-regulating agents, atorvastatin and fenofibrate on VLDL-apoC-III transport. We hypothesized that atorvastatin and fenofibrate would have similar effects on apoC-III transport by decreasing the production and increasing the catabolism of VLDL-apoC-III.
