Safety and Efficacy of Salsalate to Treat Endothelial Dysfunction in HIV-infected Adults
This is a phase II, open label, randomized-controlled pilot study designed to study both the efficacy and safety of salsalate in decreasing endothelial cell dysfunction, systemic inflammation, and insulin resistance in HIV-infected adults. The investigators hypothesis is that salsalate will reduce inflammation and therefore endothelial cell activation and insulin resistance. The sample size will be 40, with an equal number of people being randomized to one of two groups. The first arm will be randomized to salsalate therapy. The second arm will act as a control group. The study duration will be 13 weeks.

- Change in Flow Mediated Dilation (FMD) of the Brachial Artery Measured by Ultrasound Over 13 Weeks [ Time Frame: Entry and week 13 visits ] [ Designated as safety issue: No ]Flow mediated dilation (FMD) of the brachial artery was measured by ultrasound. This is a measure of endothelial dependent endothelial cell function. Flow mediated dilation is expressed as a percent change from baseline brachial artery diameter to brachial artery diameter after reactive hyperemia. Reactive hyperemia occurred after occluding the brachial artery with a blood pressure cuff for 5 minutes.

Salsalate 2 grams orally twice a day for 13 weeks. This is the maximum dosage. During the initial 9 days of the study salsalate dose will be titrated to reach this goal dosage.
