Co-infection with herpes simplex virus type 2 (HSV-2) has been associated with increased HIV-1 RNA levels and immune activation, two predictors of HIV-1 progression. The impact of HSV-2 on clinical outcomes among HIV-1 infected pregnant women is unclear.HIV-1 infected pregnant women in Nairobi were enrolled antenatally and HSV-2 serology was obtained. HIV-1 RNA and CD4 count were serially measured for 12-24 months postpartum. Survival analysis using endpoints of death, opportunistic infection (OI), ...

Sexual behavior and vaginal practices were ascertained by structured questionnaires. Logistic regression was used to assess correlates of unprotected sex, vaginal washing, and vaginal drying.Among ...

Abstract Background. A human immunodeficiency virus (HIV) risk assessment tool for pregnant women could identify women who would most benefit from preexposure prophylaxis (PrEP) while minimizing unnecessary PrEP exposure. Methods. Data from a prospective study of incident HIV among pregnant/postpartum women in Kenya were randomly divided into derivation (n = 654) and validation (n = 650) cohorts. A risk score was derived using multivariate Cox proportional hazards models and standard clinical prediction ...

Lifelong antiretroviral therapy (ART) (Option B+) is recommended for all HIV-infected pregnant/postpartum women, but high adherence is required to maximize HIV prevention potential and maintain maternal health. Mobile health (mHealth) interventions may provide treatment adherence support for women during, and beyond, the pregnancy and postpartum periods.We are conducting an unblinded, triple-arm randomized clinical trial (Mobile WACh X) of one-way short message service (SMS) vs. two-way SMS vs. control ( ...

There is growing evidence that mobile health (mHealth) approaches including short messaging service (SMS) can improve antiretroviral therapy (ART) adherence, but consensus is lacking regarding communication of HIV-related information. Most interventions to date have delivered SMS that do not overtly refer to HIV or ART in order to avoid risk of status disclosure. In formative work for an ongoing randomized controlled trial (RCT) evaluating one-way and two-way educational SMS for prevention of mother- ...

Prevention of mother-to-child HIV transmission (PMTCT) relies on long-term adherence to antiretroviral therapy (ART). Mobile health approaches, such as text messaging (short message service, SMS), may improve adherence in some clinical contexts, but it is unclear what SMS content is desired to improve PMTCT-ART adherence.We aimed to explore the SMS content preferences related to engagement in PMTCT care among women, male partners, and health care workers. The message content was used to inform an ongoing ...

To optimize scale-up of pre-exposure prophylaxis (PrEP) for pregnant women at risk of HIV in high HIV burden settings, implementation strategies must be developed that account for perceptions of PrEP in this unique population. Semistructured focus group discussions were conducted with 68 HIV-uninfected Kenyan pregnant and postpartum women without prior PrEP knowledge or experience. A qualitative descriptive analysis was performed, using a constant comparison approach, to identify key themes related ...

Objectives Recent studies have identified vaginal bacterial taxa associated with increased HIV risk.
