Objective:To investigate the incidence of first-ever stroke/transient ischemic attack (TIA) and associated risk factors in a cohort of persons living with HIV infection (PLWH). Design:Observational cohort study Methods:We determined incidence rates of first-ever stroke/TIA in PLWH after ART initiation from the AIDS Clinical Trials Group ALLRT cohort and its parent trials. Poisson regression models evaluated baseline and time-varying covariates as risk factors for stroke/TIA. Results:The incidence rate of stroke/TIA was 1.69 per 1000 person-years. Incidence rates were highest in women (2.88stroke/TIAs per 1000 person-years compared with 1.40 per 1000 person-years in men) and non-Hispanic Blacks (2.51stroke/TIAs per 1000 person-years compared with 0.77 per 1000 person-years in Hispanic/other race/ethnicities and 1.56 per 1000 person-years in whites). In a multivariable model, we found a significant age-by-sex interaction (P=0.01). The higher risk of stroke/TIA in women was more pronounced at younger ages, whereas older age conferred a greater increase in stroke/TIA risk in men than women. Other risk factors for stroke/TIA included hypertension, higher LDL, and HIV RNA greater than 200copies/ml. Overweight/obese BMI and higher CD4(+):CD8(+) ratio protected against stroke/TIA. Conclusion:Women and non-Hispanic Blacks living with HIV had the highest incidence rates of stroke/TIA. A concerted effort must be made to include PLWH from these at-risk groups in observational and interventional studies aimed at understanding stroke mechanisms and reducing stroke risk in HIV infection. Strategies to modify stroke risk in PLWH should employ a multipronged approach targeting vascular risk factors and engaging and retaining patients in HIV care.
