title: [Antiretroviral therapy and pregnancy].
abstract: Whereas the perinatal transmission rate with untreated HIV positive women is around 30%, the results of Pediatric AIDS Clinical Trials Group in 1994 showed a reduction by nearly 70% with Zidovudin chemoprophylaxis. The transmission rate can even be reduced to under 2%, if a cesarean section before onset of labour and before premature rupture of membranes is done in addition. An individualized, optimal antiretroviral combination therapy, ideally introduced in the second trimenon (in special cases even already in the first trimenon), is of great importance. As a further strategy of prevention of perinatal transmission, intravenous Zidovudin chemoprophylaxis should be given in addition to the mother during labour and to the newborn during the first six weeks of life. Besides very few exceptions, long-term data after intrauterine administration of antiretroviral therapy do not show any teratogen or other long term consequences to date. The situation in developing countries is very critical with still high transmission rates because of the lack of antiretroviral therapy due to logistical reasons and costs and the need of breastfeeding. For these reasons, more and more feasible short protocols are developed with at least fifty percent reduction of neonatal transmission rates.
