Increased coronary atherosclerosis and immune activation in HIV-1 elite controllers

Florencia Pereyra et al. AIDS. .

Abstract

HIV-1 elite controllers spontaneously maintain suppressed levels of viremia, but exhibit significant immune activation. We investigated coronary atherosclerosis by coronary computed tomography angiography (CTA) in elite controllers, nonelite controller, chronically HIV-1 infected, antiretroviral therapy (ART)-treated patients with undetectable viral load ('chronic HIV'), and HIV-negative controls. Prevalence of atherosclerosis (78 vs. 42%, P < 0.05) and markers of immune activation were increased in elite controllers compared with HIV-negative controls. sCD163, a monocyte activation marker, was increased in elite controllers compared with chronic HIV-1 (P < 0.05) and compared with HIV-negative controls (P < 0.05). These data suggest a significant degree of coronary atherosclerosis and monocyte activation among elite controllers.
