Background: Sustained virologic response to peginterferon plus ribavirin reduces liver-related complications and mortality in patients co-infected with HIV and hepatitis C virus. Therefore, the presence of any barriers to start hepatitis C virus therapy should be identified and eliminated in order to recruit all eligible patients.
Methods: Cross-sectional study.
Background: We incorporated the latest available information to evaluate the net benefit of using resistance testing in HIV-infected patients with virological failure.
Methods: Meta-analysis of randomized controlled trials comparing the clinical impact of selecting antiretroviral therapy according to results of resistance testing (phenotype or genotype) or according to the standard of care. The population studied included HIV-infected patients with virological failure.
Background And Objective: To describe the immunological, virological and clinical outcomes of HIV-infected patients who stop antiretroviral therapy (ART) and to identify the factors related to durability.
Patients And Method: Retrospective study of patients who interrupt therapy after six months without clinical events, level of CD4+ > or = 500 cells/microl and HIV RNA > or = 5,000 copies/ml (3.7 log10).
Background And Objective: Dyslipidemia, insulin resistance and body fat redistribution are respectively short and long-term complications of protease inhibitor-containing antiretroviral regimens. To establish whether differences in the type of antiretroviral therapy (protease-containing or protease-sparing) or the presence and severity of body fat redistribution, explained differences in cardiovascular risk, we undertook a cross-sectional study.
Patients And Method: The study was carried out in 219 consecutive HIV-infected patients attending an outpatient HIV clinic between February and April, 2002.
We examined the risk and determinants of developing severe liver toxicity in 108 HIV-infected patients showing adherence to nevirapine- and efavirenz-containing regimens. Between January 1997 and December 2000, 70 patients were treated with nevirapine- and 38 patients with efavirenz-containing regimens, for a median period of 127 days (interquartile range 65-240). Severe liver toxicity was defined as grade 3-4 elevations (>5 x upper limit of normal) of aminotransferases AST or ALT.
