نبذة مختصرة : 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.
