Protease inhibitors as preferred initial regimen for antiretroviral-naive HIV patients.

At present, the majority of patients who have initiated their first antiretroviral therapy have received a combination comprising a nonnucleoside and two nucleoside analogues. The use of nonnucleosides as first-line therapy has been favored for their more convenient dosing, with less pill numbers, and the possibility of co-formulation with nucleoside analogues. Although protease inhibitors are also considered to be a preferred standard, they have been less frequently used as first regimen of choice because of their adverse effects in the short to medium term.

Safety and immunogenicity of a modified pox vector-based HIV/AIDS vaccine candidate expressing Env, Gag, Pol and Nef proteins of HIV-1 subtype B (MVA-B) in healthy HIV-1-uninfected volunteers: A phase I clinical trial (RISVAC02).

Background: To investigate the safety and immunogenicity of a modified vaccinia virus Ankara vector expressing HIV-1 antigens from clade B (MVA-B), a phase-I, doubled-blind placebo-controlled trial was performed.

Methods: 30 HIV-uninfected volunteers at low risk of HIV-1 infection were randomly allocated to receive 3 intramuscular injections (1×10(8)pfu/dose) of MVA-B (n=24) or placebo (n=6) at weeks 0, 4 and 16. All volunteers were followed 48 weeks.

Lipid and apoprotein profile in HIV-1-infected patients after CD4-guided treatment interruption.

Objectives: The aims of the present study were to determine if metabolic abnormalities and cytokine derangements are modified in HIV-1-infected patients after 12 months on treatment interruption (TI).

Design: The design of this study was prospective randomized study.

Methods: Longitudinal multicenter study in HIV-1-infected patients with a 12-month follow-up.
