Declining HIV infection rates among recently married primigravid women in Pune, India.
A single recent study has suggested a decrease in HIV risk for women attending antenatal clinics (ANCs) in southern India. Yet, some have questioned the validity of the Indian national surveillance data and analyses. Previous studies suggest that the only major HIV risk factor for married Indian women is the risk behavior of their husbands. Therefore, to address concerns about potential selection bias in the analysis of sentinel surveillance data from multiple sites, we estimated the trajectory of HIV transmission rates among recently married, monogamous, primigravid women attending a single large ANC in Pune, India. ⋯ HIV infection risk among young primigravid women in Pune seems to have decreased over the past 3.5 years. A decreasing HIV risk among pregnant women in Pune would also decrease the number of HIV-exposed infants. We hypothesize that decreased high-risk sexual behavior among young recently married men is most likely contributing to a decreasing risk to their wives and children in Pune.

Condom use rather than serosorting explains differences in HIV incidence among men who have sex with men.
HIV incidence is high and increasing among men who have sex with men (MSM) attending the Sexually Transmitted Infection (STI) Outpatient Clinic in Amsterdam but remains low among MSM in the Amsterdam Cohort Studies (ACS). We studied whether sexual behaviors in these 2 groups are consistent with serosorting and if serosorting explains the difference in HIV incidence. ⋯ Sexual risk behaviors with traceable partners are consistent with serosorting. Nonetheless, the higher level of UAI with anonymous or nonconcordant traceable partners more likely explains the increasing HIV incidence seen among STI Outpatient Clinic attendees than a difference in serosorting behavior.

Comparison of clinical response to initial highly active antiretroviral therapy in the patients in clinical care in the United States and Brazil.
US and Brazilian studies indicate that highly active antiretroviral therapy (HAART) has been effective in reducing morbidity and mortality from HIV/AIDS. Differences exist in the adoption and patterns of antiretroviral drug use and in the incidence of AIDS-defining illness (ADI) between the 2 countries, however, and there has not been a direct comparison of clinical response between Brazil and the United States. We sought to determine if there have been differences in the clinical response to HAART from HIV clinical practices in the United States and Brazil. ⋯ There were only minor differences in clinical response to the use of HAART comparing Rio de Janeiro with Baltimore, despite differences in patterns of antiretroviral drug use and ADI incidence. This analysis indicates that HAART can be similarly effective in treating HIV/AIDS in countries with different economies.

Clinical TrialTriple antiretroviral prophylaxis administered during pregnancy and after delivery significantly reduces breast milk viral load: a study within the Drug Resource Enhancement Against AIDS and Malnutrition Program.
The administration of antiretroviral therapy to lactating women could represent a possible strategy to reduce postnatal HIV transmission. In this study, we assessed the effect of antiretroviral treatment on breast milk viral load and determined plasma and breast milk drug concentrations in pregnant women receiving highly active antiretroviral therapy (HAART). ⋯ Antiretroviral drugs administered during the last trimester of pregnancy and after delivery reach levels similar to or higher than plasma concentrations in breast milk and can significantly reduce HIV RNA levels. Our data support the potential role of maternal HAART prophylaxis in reducing the risk of breast-feeding-associated transmission.
