Ankle-Brachial Index and Carotid Intima-Media Thickness Progression by Using Ultrasound Among Patients With HIV Infection Versus End-Stage Renal Disease

Abstract

© The Author(s) 2020. Human immunodeficiency virus (HIV) and end-stage renal disease (ESRD) patients contributed to accelerated cardiovascular disease. Comparing the effect on atherosclerosis of the 2 diseases has never been explored. A prospective cohort study enrolled participants who were more than 18 years of age without stroke, coronary, and peripheral arterial disease events. Each HIV-infected person had continuously used antiretroviral therapy and ESRD and required intermittent hemodialysis. We assessed patients using the ankle-brachial index (ABI) and carotid intimal media thickness (CIMT) at enrollment, and 1 year later. The main outcome was the progression of ABI and CIMT per year. Demographic, comorbidities, and serum profiles were collected on entry. A total of 789 HIV-positive and 41 ESRD with HIV-negative patients were recruited. After adjusting for potential confounders at baseline, the ESRD die not significantly decrease ABI by 0.015 in 1 year (P=0.252). The HIV-infected group had a significantly decreased ABI by 0.020 in 1 year (P <.001), but the reduced rate in the HIV-infected group was not statistically different from those in the ESRD group (P = 0.901). When adjusted for potential confounders, the ESRD had a significant increase of CIMT by 0.111 mm in 1 year (P<0.001). The HIV patients had a significant increase of 0.250 mm CIMT in 1 year (P<0.001). This progression rate was statistically greater in the HIV-infected group versus the ESRD group. HIV infection and ESRD had comparable rates of ABI and CIMT progression in our study. Then, early prevention in asymptomatic atherosclerosis should include not only patients with ESRD but also HIV-infected patients.
