RESUMEN
OBJECTIVE: To analyze the outcomes of Prevention of Parent to Child Transmission (PPTCT) of HIV program in an urban Southern Indian setting. DESIGN: Observational study. SETTING: Anti-retroviral Therapy (ART) Centers/ Integrated Counseling and Testing Centers (ICTC) at four government Obstetrics Institutes in an urban area. PARTICIPANTS: 100 HIV-positive pregnant women and their infants delivered in the study centers. METHODS: Triple drug ART to HIV-positive pregnant women was started for maternal indications only. Rest of the pregnant women were given single dose Nevirapine (200 mg) at the onset of labor. All infants were given single dose Nevirapine (2 mg/kg) prophylaxis, according to National AIDS Control Organization guidelines. Mothers were counseled regarding breastfeeding and artificial feeding, and the choice was left to them. Whole blood HIV 1 DNA PCR was done for all infants at 6 weeks of life. A second PCR was done at 6 months or 6 weeks after stopping breastfeeds. PCR-positive infants were started on ART, and were followed-up till18 months of life. RESULTS: Four infants were PCR-positive for HIV. All of them were breastfed. They were born to mothers of HIV stage 1 or 2 who were not on ART as CD4 counts were >350 cells/mm3. Among the mothers in Stage 3 or 4 or CD4 count <200 cells/mm3 and on ART, none of the infants was HIV-positive. The cumulative HIV-free survival at 18 months was 94%. CONCLUSIONS: Parent-to-child transmission rate in HIV was low with the currently used strategies. Triple drug ART to mother reduces mother-to-child transmission despite advanced maternal stage or low CD4 counts.
