Key result
Mild SARS-CoV-2 infection is not linked to altered arterial stiffness or flow-mediated dilatation in HIV.
Why the study?
People with HIV have increased risk of vascular dysfunction and CVD, and SARS-CoV-2 infection is associated with acute CVD complications, prompting assessment of macrovascular function as an early CVD risk indicator.
Does recent mild SARS-CoV-2 infection worsen macrovascular function in people with well-controlled HIV?
Case-Control (n=34)
Does recent mild SARS-CoV-2 infection worsen macrovascular function in people with well-controlled HIV?
Mild SARS-CoV-2 infection does not appear to cause early macrovascular dysfunction or increase cardiovascular disease risk in people with well-controlled HIV.
No macrovascular dysfunction detected post-mild COVID in well-controlled PWH; small observational data leave longer-term CVD risk implications open.
Background: 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. Methods: 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. Results: 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. Conclusions: 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.

Salazar et al. (2025) conducted a case-control in HIV and recent mild SARS-CoV-2 infection (n=34). Recent mild SARS-CoV-2 infection vs. Pre-pandemic PWH without COVID-19 was evaluated on Macrovascular function (brachial artery flow-mediated vasodilation and arterial stiffness).
