Detaljeret beskrivelse
- To assess the effectiveness of the addition of a single dose of nevirapine (NVP) to Zidovudine (ZDV, also known as AZT) as used in the Botswana mother-to-child transmission (MTCT) National Program, in reducing transmission of HIV-1 from mother to child. To determine if maternal NVP (per HIVNET 012 protocol) is necessary in the setting of maternal ZDV from 34 weeks gestation through delivery AND single-dose prophylactic infant NVP at birth plus ZDV from birth to 4 weeks for the reduction of transmission of HIV-1 from mother to child.
- To assess the effect of prophylactic AZT given to infants during breast feeding on HIV transmission.
- To confirm the safety and tolerance of one dose of NVP given to mothers and infants
- To evaluate the safety and tolerance of AZT given to infants for up to 6 months of age
- To determine the association between assigned infant feeding strategy and maternal morbidity and mortality
- To determine the rates of virologic response to NNRTI-containing HAART at 26 and 52 weeks after initiating treatment, among HIV+ women who previously received single dose NVP versus placebo during labour.

Aktiv komparator: maternal nevirapine
|
All women received a background of zidovudine from 34 weeks' gestation through delivery, and all infants received single-dose nevirapine at birth and zidovudine from birth through 1 month.
Women were randomized to receive either single-dose nevirapine or placebo during labor.
