The association between the receipt of lipid lowering therapy and HIV status among veterans who met NCEP/ATP III criteria for the receipt of lipid lowering medication.

Overview

abstract

OBJECTIVE: To examine the association between HIV infection status and the receipt of lipid lowering therapy based on National Cholesterol Education Program/Adult Treatment Panel (NCEP/ATP III) guidelines and to assess whether HIV viral load and hepatitis C (HCV) status alters that association. PARTICIPANTS AND DESIGN: A cross-sectional analysis of survey, laboratory, and pharmacy data from 1,577 male participants (59% HIV infected) of the Veterans Aging Cohort Five-Site Study, a prospective observational cohort of U.S. veterans with and without HIV infection. MEASUREMENTS: Receipt of lipid lowering therapy obtained from the VA pharmacy benefits management system was the main outcome. RESULTS: The prevalence of lipid lowering therapy among HIV-infected and HIV-uninfected veterans was 15.4% vs. 37.9%, respectively, p < 0.01. Among veterans who met NCEP/ATP III criteria for lipid lowering therapy, HIV-infected veterans had a significantly lower prevalence for the receipt of lipid lowering therapy (adjusted odds ratio (OR) = 0.43, 95% confidence interval (C.I.) 0.28-0.67) as compared with HIV-uninfected veterans. Among HIV-infected veterans, log HIV viral load (adjusted OR = 0.57, 95% CI, 0.41-0.81) and HIV-HCV co-infection (adjusted OR = 0.31, 95% CI = 0.13-0.75) were negatively associated with receipt of lipid lowering therapy. Exposure to HAART was not associated with receipt of lipid lowering therapy. CONCLUSIONS: Among those who met NCEP/ATP III criteria for lipid lowering therapy, HIV-infected veterans, particularly those with high HIV viral loads and HCV co-infection, were significantly less likely to receive lipid lowering therapy. This may be a modifiable mediator of cardiovascular disease among HIV-infected individuals.
