Pegylated interferon (PEG-IFN) alpha2a and alpha2b differ in their pharmacokinetic properties, which might have an effect on their antiviral effects against hepatitis C virus (HCV). Differences between PEG-IFN-alpha molecules could be more pronounced in HIV-coinfected individuals, in whom response to HCV treatment is impaired. ⋯ The antiviral effect against HCV seems to be greater for PEG-IFN-alpha2a than -alpha2b in the HIV setting. A shorter half-life of PEG-IFN-alpha2b could explain this finding.

Multicenter Study
Living with HIV, antiretroviral treatment experience and tobacco smoking: results from a multisite cross-sectional study.
To assess the prevalence of and factors associated with tobacco smoking and dependence in HIV patients. ⋯ Very few HIV smokers seem to be good candidates for a standard tobacco cessation program. Tobacco reduction or cessation strategies should be adapted to this population.

A large proportion of HIV-infected patients on antiretroviral medication develop insulin resistance, especially in the context of fat redistribution. This study investigates the interrelationships among fat distribution, hepatic lipid content, and insulin resistance in HIV-infected men. ⋯ Hepatic lipid content is associated with VAT volume, especially the OMAT subcompartment, in HIV-infected men. Hepatic lipid content is associated with insulin resistance in HIV-infected men. Hepatic lipid content might mediate the relationship between VAT and insulin resistance among treated, HIV-infected men.
