Objectives: To document postpartum disease-free survival of HIV-infected women taking antiretroviral therapy (ART) during pregnancy.
Methods: Laboratory and clinical data were collected on all HIV-infected pregnant women delivering from 1998 to 2002 and followed up until September 2004 at 6 hospitals in London. Mothers were grouped according to receipt of zidovudine monotherapy (ZDVm), highly active antiretroviral therapy (HAART) given during and continued after pregnancy (cHAART), and short-term HAART given during pregnancy and discontinued on delivery (START).
Results: Eight-five women took ZDVm, 155 took cHAART, and 71 took START. The mean follow-up for all mothers was 33 months, with a total of 847 person-years. At the first antenatal clinic (ANC) visit, 72% of women were in Centers for Disease Control and Prevention (CDC) stage A, 85% were treatment naive, and the ZDVm group had a median HIV viral load (VL) 10-fold less than those mothers who started HAART during pregnancy. At last follow-up, 1 patient had died and 6 (1.9%) had progressed to CDC stage C; 62% of all women, including a quarter of the ZDVm group, were receiving HAART for their own health; and 83% of all mothers had a VL <50 HIV RNA copies/mL of plasma regardless of whether they were on treatment or not.
Conclusions: The median-term postpartum prognosis of HIV-infected pregnant women with access to HAART is good. Exposure to short-course ZDVm or START during pregnancy did not jeopardize their response to subsequent therapy.
