    Abstract:
    BACKGROUND: Cotrimoxazole prophylaxis is recommended for subgroups of human immunodeficiency virus (HIV)-infected adults and children to reduce all-cause morbidity and mortality. We investigated whether antenatal cotrimoxazole prophylaxis begun during pregnancy for HIV-infected pregnant women with low CD4 cell counts would affect birth outcomes. METHODS: Cotrimoxazole prophylaxis was introduced as a routine component of antenatal care for HIV-infected women with CD4 cell counts <200 cells/ micro L during the course of a trial of mother-to-child HIV transmission in Lusaka, Zambia. Rates of preterm delivery, low birth weight, and neonatal mortality were compared for women with low CD4 cell counts before and after its introduction. RESULTS: Among 255 women with CD4 cell counts <200 cells/ micro L, the percentage of preterm births (< or =34 weeks of gestation) was lower (odds ratio [OR], 0.49 [95% confidence interval {CI}, 0.24-0.98]) after cotrimoxazole prophylaxis was introduced than before; there was a significant decrease in neonatal mortality (9% to 0%; P=.01) and a trend toward increased birth weight ( beta =114 g [95% CI, -42 to 271 g]). In contrast, there were no significant changes in these parameters over the same time interval among women with CD4 cell counts > or =200 cells/ micro L.Conclusion. Antenatal provision of cotrimoxazole for HIV-infected pregnant women with low CD4 cell counts may have indirect benefits for neonatal health.
