Measure
TZV Arm
Participants in Arm 1A will have CD4 counts of 200 cells/mm3 or more and will receive TZV twice daily. Once in labor, these participants will continue to take TZV twice daily and will also be given additional ZDV. Trizivir: 300 mg abacavir sulfate/150 mg lamivudine/300 mg zidovudine tablet taken orally twice daily
Kaletra Arm
Participants in Arm 1B will have CD4 counts of 200 cells/mm3 or more and will receive LPV/RTV and 3TC/ZDV twice daily. Once in labor, these participants will continue to take TZV twice daily and will also be given additional ZDV. Lamivudine/Zidovudine: 150 mg lamivudine/300 mg zidovudine tablet taken orally twice daily Lopinavir/Ritonavir: 400 mg lopinavir/100 mg ritonavir tablet taken orally twice daily
NVP Arm
Participants in Arm 2 will have CD4 counts less than 200 cells/mm3 and will receive NVP once daily for the first 14 days, then twice daily, and 3TC/ZDV twice daily; these women will be in the observational group. Nevirapine: 200 mg tablet taken orally daily for the first 14 days before receiving 200 mg tablet taken orally twice daily
