Prevalence, Incidence, and Contributors of Subclinical Atheromatosis, Arteriosclerosis, and Arterial Hypertrophy in HIV-Infected Individuals: A Single-Center, 3-Year Prospective Study.

Cardiovascular disease (CVD) is an important comorbidity for people living with HIV infection (PLWH) in the combined antiretroviral therapy era. We prospectively examined the presence of subclinical arterial disease in 138 consecutive CVD-free, HIV-infected individuals compared to 664 HIV-negative individuals. We studied 10 arterial sites in 4 beds using 5 distinct biomarkers of subclinical atheromatosis, arteriosclerosis, and hypertrophy and evaluated the association of subclinical arterial damage with CVD-related and HIV-related factors at baseline and at 3-year follow-up. Atheromatosis, arteriosclerosis, and arterial hypertrophy were present in 36.1%, 59.7%, and 34.3% of HIV-infected individuals, respectively, at baseline. HIV infection was independently associated with carotid atheromatosis and hypertrophy. The presence of carotid atheromatosis was independently associated with age, years of smoking, and exposure to nonnucleoside reverse transcriptase inhibitors (NNRTIs). The annual incidence of atheromatosis, arteriosclerosis, and arterial hypertrophy was 5.5, 18.6, and 12.5 cases/100 patients, respectively. Carotid atheromatosis progression was significantly associated with NNRTI exposure. People living with HIV infection exhibited high prevalence and incidence of subclinical arterial damage and site-specific predilection for the carotids. These investigations may help optimize HIV-specific CVD prediction models. The NNRTIs may contribute to atheromatosis, emphasizing the need to consider the atherogenic potential of antiretroviral drugs in management strategies.
