Evaluation of factors associated with vertical HIV-1 transmission

Evaluation of factors associated with vertical HIV-1 transmission.

OBJECTIVE To compare the prevalence and factors associated with vertical transmission of human immunodeficiency virus 1 (HIV-1) among pregnant women treated in the periods of 1998-2004 and 2005-2011 in a reference service for the care of HIV-infected patients in southern Brazil. METHODS This was a descriptive and analytical study that used the databases of laboratories from the CD4 and STDs/A...

Maternal and Perinatal Risk Factors Associated with Vertical Transmission of Hiv-1 Infection from Mother to Child

In 2009, the US Centers for Disease Control and Prevention (CDC) estimated that almost 11,000 children younger than 13 years old in the United States were diagnosed with HIV infection. Of those, it is estimated that the vast majority (88%) acquired the HIV infection perinatally. Given that both perinatal transmission is the most common route of HIV infection in children under 13 in the US and t...

Late postnatal transmission of HIV-1 and associated factors.

BACKGROUND The present study was undertaken to determine the risk and timing of late postnatal transmission (LPT) of human immunodeficiency virus type 1 (HIV-1). METHODS Breast-fed infants previously enrolled in 2 trials of antiretroviral prophylaxis were monitored in Malawi. Kaplan-Meier and proportional hazard models assessed cumulative incidence and association of factors with LPT. RESUL...

Features of Maternal HIV-1 Associated with Lack of Vertical Transmission

HIV-1 is transmitted from mother-to-child (vertical transmission) at an estimated rate of approximately 30% without any antiretroviral therapy (ART). However, administration of ART during pregnancy considerably diminishes the rate of mother-to-child transmission of HIV-1, which has become a standard of perinatal care in HIV-infected pregnant females in developed countries. Moreover, a majority ...
