Nevirapine Resistance Study: Nevirapine Resistance Among HIV-Infected Mothers

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine whether the addition of zidovudine (ZDV) and lamivudine (3TC) at the onset of labor and for up to seven days postpartum to single-dose nevirapine (NVP) is associated with a lower prevalence of NVP-resistant HIV compared to single-dose NVP without ZDV+3TC.

Detailed Description
-----------------
The primary purpose of the Nevirapine Resistance Study is to compare nevirapine (NVP) resistance of HIV at two and six weeks postpartum in women who are participating in two different programs currently ongoing in Lilongwe, Malawi. The first program is through the HIV Infection and Breastfeeding: Interventions for Maternal and Infant Health, also known as the Breastfeeding, Antiretrovirals and Nutrition (BAN) Study, a clinical trial where all enrolled women receive zidovudine (ZDV) and lamivudine (3TC) at the onset of labor and for up to seven days postpartum in addition to single-dose nevirapine (NVP). The second program is the Call to Action (CTA) program sponsored by the Malawi Ministry of Health and Population (MOHP) and UNC Project. The aim of the CTA program is to reduce mother to child transmission (MTCT) of HIV by providing women a single dose NVP to be taken at the onset of labor. Study participants are tested for NVP-resistant HIV at two and six weeks postpartum and the prevalence of NVP-resistant virus is compared among the two groups receiving different peripartum anti-retroviral regimens.
