【 摘 要 】

INTRODUCTION: Antiretroviral therapy and prophylaxis during the antepartum, intrapartum and postpartum periods, cesarean delivery and avoidance of breast milk significantly reduce vertical transmission of HIV.OBJECTIVE:To evaluate the effectiveness prevention of mother-to-child transmission of HIV and determine the rate of vertical transmission in a public sexually transmitted infection and HIV referral center in Salvador, Bahia, in the period immediately prior to the initiation of universal antiretroviral therapy in pregnant women.METHODS:Cross-sectional study using data collected from medical records of children born to HIV infected mothers in Bahia from 2005 to 2008 who were referred to the Reference Center for Diagnosis and Research of Sexually Transmitted Diseases and HIV/AIDS for care.RESULTS:Of 232 HIV-exposed infants, 19 (8.2%) had confirmed HIV infection. One hundred eighty-eight (81%) mothers received antenatal care, 120 (52%) antepartum antiretroviral therapy or prophylaxis, and 168 (72%) intrapartum zidovudine. Two hundred twenty-three (96%) infants received zidovudine. In multivariable models, the combination of intrapartum and postpartum antiretroviral prophylaxis was associated with decreased adjusted odds of mother-to-child transmission.CONCLUSIONS:Low levels of antenatal screening and access to prevention of mother-to-child transmission were significant limitations in the cascade of prevention of mother-to-child transmission at our center in this period.
