Study of Perinatal Transmission of Zidovudine-Resistant HIV Among Pregnant Women Treated With Zidovudine
Study of Perinatal Transmission of Zidovudine-Resistant HIV Among Pregnant Women Treated With Zidovudine

To identify patterns of zidovudine ( AZT ) susceptibility among mother/infant pairs with perinatal HIV transmission.

Most HIV-infected infants acquire their disease via perinatal transmission. Since transmission of HIV-resistant strains to infants could alter the course of disease and response to currently recommended treatment, a study to assess the patterns of AZT susceptibility among mother/infant pairs with perinatal transmission is essential to delineate future therapeutic strategies.

HIV-infected pregnant women are enrolled at 20-36 weeks gestation. Patients have blood drawn for HIV culture at study entry and at delivery. Infants have blood drawn for HIV culture at delivery and at 1, 3, 6, and 18 months of age.
