Macrovascular Function in People with HIV After Recent SARS-CoV-2 Infection

People with HIV (PWH) are at increased risk of vascular dysfunction and cardiovascular disease (CVD). SARS-CoV-2 infection has been associated with acute CVD complications. The aim of the study was to as-sess macrovascular function as an early indicator of CVD risk in PWH after mild SARS-CoV-2 infection.

PWH aged 20-60 years, with undetectable viral load (RNA < 20 copies/mL), on stable antiretroviral therapy (≥6 months) and history of mild COVID-19 (≥30 days) without any CVD manifestations prior to enrollment were recruited. Participants were excluded if they had history of diabetes mellitus, end-stage renal disease, heart or respiratory disease. Participants were matched 1:1 to pre-pandemic PWH. A health survey, surrogate measures of CVD risk, and macrovascular function (brachial artery flow-mediated vasodilation and arterial stiffness assessments via applanation tonometry) were compared between group.

A total of 17 PWH and history of COVID-19 (PWH/COV+) were matched with 17 PWH without COVID-19 (PWH/COV-) pre-pandemic. Mean age (45.5 years), sex (76.5% male), body mass index (27.3), and duration of HIV infection (12.2 years) were not different between groups. Both groups had comparable CVD risk factors (total cholesterol, LDL, HDL, systolic and diastolic blood pressure). There were no differences in measures of flow mediated arterial dilatation or arterial stiffness after 30 days of SARS-CoV-2 infection.

After recent SARS-CoV-2 infection, PWH did not demonstrate evidence of macrovascular dysfunction and increased CVD risk. Results suggest that CVD risk may not be increased in people with well-controlled HIV who did not manifest CVD complications SARS-CoV-2 infection.
