摘要: OBJECTIVES: To determine the impact of time between initiating highly active antiretroviral therapy (HAART) and delivery-duration antenatal HAART-on perinatal HIV infection. DESIGN: We conducted a retrospective cohort analysis pregnant HIV-infected women in Lusaka Zambia. Women our were receiving HAART had an infant polymerase chain reaction test 3 12 weeks life. METHODS: examined factors associated with infection performed locally weighted regression to examine effect duration on RESULTS: : From January 2007 March 2010 1813 met inclusion criteria. Mean gestational age at first visit was 21 (SD +/- 6) median CD4+ cell count 231 cells per microliter (interquartile range: 164-329) 13 range 8-19). Fifty-nine (3.3%) infants infected. Duration most important predictor transmission. Compared least before delivery for =4 5.5-fold increased odds transmission (95% confidence interval: 2.6 11.7). Locally suggested limited additional prophylactic benefit beyond HAART. CONCLUSIONS: Low rates mother-to-child can be achieved within programmatic settings Africa. Maximal effectiveness prevention programs is by delivery.
