HIV-specific immune dysregulation and atherosclerosis

Curr HIV/AIDS Rep. 2012 Sep;9(3):200-5. doi: 10.1007/s11904-012-0123-y.

Abstract

HIV + patients face a heightened risk of cardiovascular disease (CVD), which cannot be fully explained by traditional risk factors or antiretroviral therapy (ART)-related cardiotoxicity. Increasing evidence suggests a significant contribution of HIV-specific immune dysregulation to atherosclerosis. HIV-specific immune dysregulation may have the following atherogenic effects: 1) activation of endothelial and immune cells; 2) enhancement of the percentage of circulating atherogenic immune cell subsets; and 3) modification of lipid function. Efforts are underway to link immune dysregulation markers with validated CVD endpoints and to identify genetic predispositions for HIV-induced atherogenesis. Moreover, immune suppressants are under evaluation in HIV + patients to attempt modification of immune-mediated CVD risk. Taken together, these studies will enhance understanding of CVD risk stratification and reduction strategies in HIV.
