  Purpose

Patients with rheumatoid arthritis have a significantly higher risk to develop heart attacks and other complications of their blood vessels. New therapies are needed to prevent this complication. The purpose of this study is to establish the role of the medication pioglitazone in improving the function of the blood vessels and heart and decreasing the risk of future atherosclerosis development in individuals with rheumatoid arthritis. As a secondary aim-point, we will evaluate the efficacy of pioglitazone in improving rheumatoid arthritis disease activity and markers of inflammation.

Primary Outcome Measures:
  • The primary goal of the project is to evaluate the efficacy of pioglitazone a PPAR-gamma agonist, in improving markers of endothelial dysfunction and atherosclerosis risk in rheumatoid arthritis. [ Time Frame: 11/2007-7/2012 ] [ Designated as safety issue: Yes ]
  • Decrease in inflammation. [ Time Frame: 8 mo ] [ Designated as safety issue: No ]
    By decreasing inflammation may prevent atherosclerosis and heart attacks. The study will also evaluate if pioglitazone improves the symtoms of rheumatoid arthritis.


Secondary Outcome Measures:
  • As a secondary outcome measure we will evaluate the efficacy of pioglitazone in improving rheumatoid arthritis disease activity and markers of inflammation. [ Time Frame: 11/2007-07/2012 ] [ Designated as safety issue: No ]
  • Risks or side effects to pioglitazone. [ Time Frame: 11/2007-07/2012 ] [ Designated as safety issue: Yes ]
    If there are adverse events during the study they are recorded and reported.

Detailed Description:

This study will establish the role of pioglitazone in improvement of endothelial function, arterial compliance and disease activity in patients with rheumatoid arthritis. This will be a placebo-controlled, double blind, cross-over trial.
