Effect of darunavir on lipid profile in HIV-infected patients

Abstract

Highly active antiretroviral therapy regimens, consisting of a ritonavir-boosted protease inhibitor (PI) and 2 nucleoside reverse transcriptase inhibitors, are established first-line regimens for HIV-infected patients. However, a common adverse effect in patients receiving PIs is dyslipidemia, characterized by increases in plasma levels of triglycerides, low-density lipoprotein cholesterol, and total cholesterol (TC). These lipid changes, as well as other well-described risk factors, may predispose patients to the development of cardiovascular disease, an important comorbidity, especially as the lifespan of HIV-infected patients has increased dramatically in recent years. Among PIs, ritonavir-boosted atazanavir (ATV/r) and, more recently, ritonavir-boosted darunavir (DRV/r) have demonstrated potent antiviral efficacy with more favorable lipid profiles than other PIs. This review provides an overview of the lipid effects of DRV/r. Studies with DRV/r in healthy volunteers and in both treatment-naïve and -experienced patients have demonstrated that changes in tri-glycerides and TC are comparable to those seen with ATV/r. © 2012 Thomas Land Publishers, Inc.
