Study Details

Study Description

Brief Summary

The investigators are studying whether an anti-inflammatory intervention improves impaired coronary endothelial function (CEF) in HIV+ people with no clinical coronary artery disease (CAD).

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

Survival in people with HIV has significantly improved with the use of antiretroviral therapy (ART) but HIV+ people now experience an increasing burden of chronic diseases, including coronary atherosclerosis and coronary artery disease (CAD). HIV patients manifest an increased risk of CAD and its consequences possibly due to interplay of inflammation with traditional risk factors (smoking, high cholesterol, and poor diet), some of the latter accentuated by ART.

What the investigators are studying in this program is the function of the coronary arteries and in particular the inner lining of the arteries called the endothelium in patients with HIV. The endothelium has several important functions; one of them is that under conditions of stress it releases a substance called nitric oxide which increases the size of the artery and increases blood flow. When it is not functioning normally the artery does not increase as much and blood flow does not increase during stress.

The investigators study coronary artery function with magnetic resonance imaging, or MRI. MRI is a method of obtaining images of what is happening inside the body. MRI does not involve radiation, x-ray, or injection of contrast. The investigators can measure flow in the artery and the dimension of the artery at rest and with a handgrip stress and learn the extent to which the artery dilates and flow increases with the stress. The investigators believe that inflammation can interfere with normal function and that by decreasing inflammation abnormal endothelial function may be improved.

Colchicine is an anti-inflammatory agent approved by the Food and Drug Administration (FDA) to treat arthritis and some other conditions. This drug is not approved for use to suppress inflammation in patients with coronary artery disease and improve coronary artery endothelial function. The FDA is allowing the use of colchicine or a placebo in this research study.

This study will involve 24 weeks of colchicine or placebo and 3 Magnetic Resonance Imaging (MRI) scans of the heart and other study procedures.
