Background: The independent role of HCV genotype 3 (HCV-3) in dyslipidaemia following highly active anti-retroviral therapy (HAART) is still unexplored. Methods: 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 hypertriglyceridaernia (>= 500 mg/dI) and relevant hypercholesterolaemia (>= 240mg/dl) at 3 months of follow-up. Results: 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 < 0.001). At logistic regression analyses, HCV-3, but not HCV-non-3, was associated with lower risk of relevant hypercholesterolaemia (odds ratio [OR] 0.06; P=0.01) and relevant hypertriglyceridaernia (OR 0.11; P=0.05), independently from other considered variables. Conclusions: Our data confirm that HCV coinfection per se is associated with lower risk of hypercholesterolaemia after HAART. This effect was particularly attributed to HCV-3, which was the only genotype associated with lower triglyceridaemia during HAART.

Abstract
Background: The independent role of HCV genotype 3 (HCV-3) in dyslipidaemia following highly active anti-retroviral therapy (HAART) is still unexplored. Methods: 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 hypertriglyceridaernia (>= 500 mg/dI) and relevant hypercholesterolaemia (>= 240mg/dl) at 3 months of follow-up. Results: 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.
