Influence of hepatitis c genotypes on lipid levels in HIV-positive patients during highly active antiretroviral therapy

The independent role of HCV genotype 3 (HCV-3) in dyslipidaemia following highly active antiretroviral therapy (HAART) is still unexplored. Analysis of data from a cohort of 307 HIV/HCV-coinfected patients and 415 HIV-monoinfected controls was conducted. Patients with available lipid levels at baseline and minimum 3-month follow-up were ranked into three groups by HCV status (HCV-3, other HCV genotypes or HCV negative). Univariate and multivariate GEE models were performed to assess factors correlated with lipid serum levels as coefficient (Coef., defined as mean difference [mg/dl] across the follow-up). Univariate and multivariate logistic regression analyses were performed for prediction of relevant hypertriglyceridaemia (> or = 500 mg/dl) and relevant hypercholesterolaemia (> or = 240mg/dl) at 3 months of follow-up. HCV-3 correlated with lower triglyceridaemia (Coef.=-38.22; P=0.001), independently from the other considered variables, including age, gender and use of stavudine or lopinavir. Even though HCV infection per se appeared to be protective, HCV-3 in particular was also independently associated with lower cholesterolaemia (Coef.=-46.35; P
