Abstract
Objectives: Alterations in lipids and apolipoproteins contribute to cardiovascular disease (CVD) and are common in people with HIV. The aim of our study was to compare lipid profiles and body composition between people with and without HIV and to explore whether any associations with HIV could be explained by socio-demographic, clinical characteristics and body composition.
Methods: Cross-sectional analysis of a cohort study enrolling people with HIV and HIV-negative controls. Apolipoproteins [ApoB-100, ApoA1, Lp(a)] were analysed by immunoturbidimetry. Lipids (total cholesterol [TC], low-density lipoprotein [LDL], high-density lipoprotein [HDL]), clinical/demographic data and dual-energy X-ray absorptiometry (DXA)-measured body composition parameters were collected. Between-group differences were assessed with Student's T-test. Linear regression models assessed associations of lipids and apolipoproteins with HIV status and associations with socio-demographic, clinical characteristics and body composition.
Results: We included 108 people with HIV on treatment (93.5% with viral suppression) and 96 controls. People with HIV were younger, more likely to be male, with obesity, of African ethnicity, smokers and with a higher representation of CVD, hypertension, diabetes and statin use. ApoB-100, TC, HDL and LDL were significantly lower in people with HIV, with no between-group difference in ApoA, Lp(a) and body composition. HIV infection remained independently associated with lower TC and LDL after adjustment for possible confounders.
Conclusions: People with HIV from a contemporary cohort had lower pro-atherogenic lipid parameters compared to controls, and no differences in body composition between people with HIV and controls were observed. Traditional risk factors for CVD and chronic inflammation might have a greater impact than dyslipidaemia itself on the increased CVD risk in people with HIV.
期刊介绍:
HIV Medicine aims to provide an alternative outlet for publication of international research papers in the field of HIV Medicine, embracing clinical, pharmocological, epidemiological, ethical, preclinical and in vitro studies. In addition, the journal will commission reviews and other feature articles. It will focus on evidence-based medicine as the mainstay of successful management of HIV and AIDS. The journal is specifically aimed at researchers and clinicians with responsibility for treating HIV seropositive patients.
