Antiretroviral Therapy Around Childbirth Reduces Risk Of Mother-To-Child HIV-1 Transmission (pp 1168, 1178)
Antiretroviral therapy given to women before, during, and after childbirth could be beneficial in reducing mother-to-child HIV-1 transmission in the first few weeks after delivery, suggest authors of a study in this week's issue of THE LANCET. However, this short-term benefit could be compromised unless new interventions are identified to prevent... view more... (2002-04-04)
Prolonged nevirapine in breast-fed babies prevents HIV infection but leads to drug-resistant HIV
Babies born to HIV-positive mothers and given the antiretroviral drug nevirapine through the first six weeks of life to prevent infection via breast-feeding are at high risk for developing drug-resistant HIV if they get infected anyway, a team of researchers report. view more (2009-01-06)
Anti-HIV Therapy Boosts Life Expectancy
The life expectancy for patients with human immunodeficiency virus (HIV) has increased by more than 13 years since the late 1990s thanks to advancements in antiretroviral therapy, according to researchers at the University of Alabama at Birmingham (UAB) and Simon Fraser University in Vancouver, British Columbia. view more (2008-07-28)
