HIV Infections

Protease inhibitors and non-nucleoside reverse transcriptase inhibitors have a comparable effect on the CD4 cell change after switching to tenofovir-based regimens

Cytomegalovirus rather than HIV triggers the outgrowth of effector CD8+CD45RA+CD27- T cells in HIV-1-infected children

OBJECTIVE: To analyse the effect of viral coinfections on immune reconstitution in HIV-1-infected children (textless 18 years) taking highly active antiretroviral therapy (HAART). METHODS: Absolute lymphocyte numbers of various subsets of CD8 T cells …

Plasma HIV-1 RNA decline within the first two weeks of treatment is comparable for nevirapine, efavirenz, or both drugs combined and is not predictive of long-term virologic efficacy: A 2NN substudy

BACKGROUND: The initial rate of plasma HIV-1 RNA (pVL) decline has been proposed as a marker of early efficacy of antiretroviral therapy (ART) and a possible predictor of late efficacy. We compared the rate of pVL decline in patients starting ART …

The effect of baseline CD4 cell count and HIV-1 viral load on the efficacy and safety of nevirapine or efavirenz-based first-line HAART

BACKGROUND: A substantial number of patients start their first-line antiretroviral therapy at an advanced stage of an HIV-1 infection. Potential differences between specific drug regimens in antiviral efficacy and safety in these patients are of …

Are adverse events of nevirapine and efavirenz related to plasma concentrations?

OBJECTIVE: The relationships between adverse events (AEs) and plasma concentrations of nevirapine (NVP) and efavirenz (EFV) were investigated as part of the large, international, randomized 2NN study. METHODS: Treatment-naive, HIV-1-infected patients …

Nevirapine and efavirenz pharmacokinetics and covariate analysis in the 2NN study

OBJECTIVE: The aim of this 2NN pharmacokinetic substudy was to investigate the population pharmacokinetics of nevirapine and efavirenz. METHODS: Treatment-naive, HIV-1-infected patients received nevirapine (once or twice daily), efavirenz or a …

Nevirapine and efavirenz elicit different changes in lipid profiles in antiretroviral-therapy-naive patients infected with HIV-1

BACKGROUND: Patients infected with HIV-1 initiating antiretroviral therapy (ART) containing a non-nucleoside reverse transcriptase inhibitor (NNRTI) show presumably fewer atherogenic lipid changes than those initiating most ARTs containing a protease …

Quality of life in patients treated with first-line antiretroviral therapy containing nevirapine and/or efavirenz

OBJECTIVE: To assess whether differences in safety profiles between nevirapine (NVP) and efavirenz (EFV), as observed in the 2NN study, translated into differences in 'health related quality of life' (HRQoL). DESIGN: A sub-study of the 2NN study, …

Highly active antiretroviral therapy with or without mycophenolate mofetil in treatment-naive HIV-1 patients

OBJECTIVE: To study the effect of mycophenolate mofetil (MMF) on the decay rate of plasma HIV-1 RNA and the latently infected cellular reservoir in treatment-naive patients starting antiretroviral therapy. DESIGN:: Randomized trial. METHODS: A group …

Comparison of first-line antiretroviral therapy with regimens including nevirapine, efavirenz, or both drugs, plus stavudine and lamivudine: a randomised open-label trial, the 2NN Study

BACKGROUND: The 2NN Study was a randomised comparison of the non-nucleoside reverse-transcriptase inhibitors (NNRTI) nevirapine and efavirenz. METHODS: In this multicentre, open-label, randomised trial, 1216 antiretroviral-therapy-naive patients were …
