Effect of HIV duration on ambulatory blood pressure in HIV-infected individuals with high office blood pressure

AbstractObjective. There is a scarcity of data on ambulatory blood pressure (ABP) in HIV-infected individuals. The aim of the study was to identify possible predictors of ABP in HIV-infected individuals. Methods. From a cohort of 542 HIV-infected patients, ABP monitoring was undertaken in 77 patients with high office blood pressure (BP) readings and without antihypertensive treatment. Results. 24-h and daytime ABPs were associated with HIV duration (r=0.24–0.33, p=0.004–0.033), but not with duration of combined antiretroviral therapy. In multivariate linear regression analyses with the different ABPs as dependent variables, HIV duration (unstandardized β=0.41–0.89, p=0.008–0.045) and log-transformed urinary albumin excretion (p=0.003–0.043) were predictors of all 24-h and daytime ABPs. Multiple logistic regression analysis revealed HIV duration (OR=1.14/year (95% CI 1.03–1.26)) as predictor of hypertension defined according to daytime ABP. Nocturnal hypertension was observed in 81%, white coat hypertensio...
