ABSTRACT
OBJECTIVE:
Previous research indicates an increased risk of cerebral aneurysm formation in adults living with human immunodeficiency virus (ALWH), however there are few longitudinal studies on the risk factors for and outcomes of cerebral aneurysms in this population. We aim to describe the characteristics and evolution of cerebral aneurysms in a large cohort of ALWH. MATERIALS ANDMETHODS:
A chart review was completed for all adults evaluated at an urban, safety-net U.S. hospital between January 1, 2000, and October 22, 2021, with history of both HIV and at least one cerebral aneurysm.RESULTS:
A total of 82 cerebral aneurysms were identified amongst 50 patients (52% female sex). Forty-six percent of patients with a nadir CD4 count less than 200 cells/mm3 (N=13) and 44% of patients with maximum viral load >10,000 copies/mL (N=18) developed new aneurysms or were found to have aneurysm growth over time compared with 29% of patients with a CD4 nadir above 200 cells/mm3 (N=21) and 22% of patients with maximum viral load = 75 copies/mL (N=9). New aneurysms were found, or existing aneurysms grew in 67% of those not on antiretroviral therapy (ART) at time of aneurysm diagnosis (N=6), 38% of those with inconsistent ART use (N=8), and 21% of those with consistent ART (N=19).CONCLUSIONS:
Among ALWH, lower CD4 nadir, higher zenith viral load, and inconsistent ART use may contribute to aneurysm formation or growth. Further studies are needed to more thoroughly characterize the association between immunologic status and cerebral aneurysm formation.Key words
