Authors: Burger DM, Bergshoeff A, de Groot R, et al; on behalf of the PENTA 5 study group.

Published in: J Paediatr 2004;145(3):403-405

Abstract Differences in virologic response were compared in 32 HIV-infected children with a nelfinavir trough concentration either below (n=7) or above (n=25) 0.8 mg/L. Virologic response at week 48 was observed in 29% of children with subtherapeutic nelfinavir troughs versus 80% in children with therapeutic nelfinavir troughs (P=.02)

Effect of concurrent zidovudine use on the resistance pathway selected by abacavir-containing regimens

2004

Authors: Lanier ER, Givens N, Stone C, et al.

Published in: HIV Med. 2004;5(6):394-399

Objectives Abacavir (ABC) selects for four mutations (K65R, L74V, Y115F and M184V) in HIV‐1 reverse transcriptase (RT), both in vitro and during monotherapy in vivo. The aim of this analysis was to compare the selection of these and other nucleoside reverse transcriptase inhibitor (NRTI)‐associated mutations by ABC‐containing therapies in the presence and absence of concurrent lamivudine (3TC) and/or zidovudine (ZDV) and to assess the effect of these mutations on phenotypic susceptibility to the NRTIs.

Abstract In 25 vertically HIV-infected children receiving highly-active antiretroviral therapy, a 3-log10 reduction in plasma HIV RNA load was maintained for 1 year and was associated with a doubling of the CD4-cell percentage. Most (75%) new CD4 cells carried the CD45RA marker of naive cells and there was only a small rise in memory cells (CD45RO).

Objective The study aimed to explore the experience of parents/care-givers to their child’s participation in a European randomized trial of immediate (zidovudine) with deferred (placebo) antiretroviral treatment in asymptomatic children with vertically acquired HIV infection (PENTA 1 trial).

Design One hundred and thirty-three questionnaires were distributed to parents/care-givers (68% of children in the trial) through their paediatrician prior to unblinding the individual child’s therapy (zidovudine/placebo) and 84 (63% response rate) were returned.
