A retrospective survey to estimate the prevalence of hepatitis B (HBV) and C (HCV) infections was conducted on the samples of 247 African HIV-1 positive pregnant women who had participated to a mother-to-child prevention trial carried out in urban settings in Kampala, Uganda and Kigali, Rwanda. Hepatitis B markers studied were HBs antigen (HBsAg) and, if(More)
BACKGROUND Recent data have shown that plasma levels of lipopolysaccharide (LPS) are a quantitative indicator of microbial translocation in HIV infected individuals. OBJECTIVES To assess the impact of residual viral replication on plasma LPS in HAART-treated HIV+ subjects with <50copies/ml HIV-1 RNA and to evaluate LPS changes during repeated HAART(More)
BACKGROUND The use of simplified methods for viral load determination could greatly increase access to treatment monitoring of HIV patients in resource-limited countries. OBJECTIVE The aim of the present study was to optimize and evaluate the performance of the Roche COBAS Taqman assay in HIV-RNA quantification from dried blood spots (DBS) and dried(More)
Clinical, virologic, and immunologic outcomes were analyzed in children with vertically transmitted human immunodeficiency virus (HIV) infection (n = 25) and clinical symptoms and evidence of immunosuppression to establish the efficacy of 18 months' treatment with stavudine, lamivudine, and indinavir. Children were naive for treatment with protease(More)
Some studies on untreated patients have shown a general correlation between plasma HIV copy number and plasma infectivity in in vitro models. Recent observations also indicate that HIV-RNA level is an important predictor of perinatal transmission and may also have a role in heterosexual transmission. To further analyse the correlation between HIV viral load(More)
DESIGN Despite significant rises in total CD4 T cells, the process of immune reconstitution in adults with HIV infection treated with potent antiretroviral treatment results in a rather slow increase in phenotypically naive lymphocytes. In children more than in adults, thymic function may be at least partly restored when disease-induced immunosuppression is(More)
OBJECTIVE The development of drugs that can be used as topical microbicides is currently recognized as a priority area of research. DESIGN A preclinical evaluation of the potential effectiveness of TMC120, a non-nucleoside reverse transcriptase inhibitor (NNRTI), as a topical microbicide to prevent vaginal HIV-1 transmission in a humanized severe combined(More)
BACKGROUND Optimized preventive strategies are needed to reach the objective of eliminating pediatric AIDS. This study aimed to define the determinants of residual HIV transmission in the context of maternal antiretroviral therapy (ART) administration to pregnant women, to assess infant safety of this strategy, and to evaluate its impact on maternal(More)
BACKGROUND Limited information is available on antiretroviral concentrations in women/infant pairs receiving prophylaxis for breastfeeding transmission of HIV and on the relationship between drug levels and the virological and haematochemistry parameters. METHODS Patient population included HIV-positive pregnant women receiving antiretroviral prophylaxis(More)
BACKGROUND Most of the studies evaluating rash in HIV-positive patients have focused on nonnucleoside reverse transcriptase inhibitors (NNRTI), particularly nevirapine, and little is known about the occurrence of rash and the risk factors for its development in patients receiving regimens not based on NNRTI. METHODS We evaluated all cases of rash observed(More)
