Use of zidovudine-sparing HAART in pregnant HIV-infected women in Europe: 2000-2009

Increasing numbers of women in resource-rich settings are prescribed zidovudine (ZDV)-sparing highly active antiretroviral therapy (HAART) in pregnancy. We compare ZDV-sparing with ZDV-containing HAART in relation to maternal viral load at delivery, mother-to-child transmission (MTCT) of HIV, and congenital abnormality. This is an analysis of data from the National Study of HIV in Pregnancy and Childhood and the European Collaborative Study.

Overall, 15.8% (1199 of 7573) of women received ZDV-sparing HAART, with increasing use between 2000 and 2009 (P
