Bullying and ART Nonadherence Among South African ALHIV: Effects, Risks, and Protective Factors.

Marisa Casale, Lucie Cluver, Mark Boyes, Elona Toska, Laurie Gulaid, Alice Armstrong, Yulia Shenderovich, William E Rudgard, Siyanai Zhou, Nontokozo Langwenya,

<h4>Background</h4>Identifying risk and protective factors for adolescent antiretroviral therapy (ART) adherence is a public health priority, given high HIV-related mortality in this population. An area that merits further investigation is the relationship between bullying victimization, mental health problems, and ART nonadherence among adolescents living with HIV (ALHIV). However, no known ... Read more >>

Reproductive aspirations, contraception use and dual protection among adolescent girls and young women: the effect of motherhood and HIV status.

Elona Toska, Lucie Cluver, Christina A Laurenzi, Camille Wittesaele, Lorraine Sherr, Siyanai Zhou, Nontokozo Langwenya,

<h4>Introduction</h4>There is a growing interest in adolescent motherhood and HIV among policymakers and programme implementers. To better shape services and health outcomes, we need evidence on reproductive aspirations and contraception use in this high-risk group, including the effect of motherhood and HIV status. We report data from a large survey ... Read more >>

Risk-based screening to identify reproductive tract infection among HIV-infected women desiring use of intrauterine contraceptives.

Nontokozo Langwenya, Catherine S Todd, Heidi E Jones, Donald R Hoover, Nai-Chung Hu, Agnes Ronan, Landon Myer,

<h4>Background</h4>Reproductive tract infections (RTIs) are a major cause of morbidity and mortality, yet RTI testing remains limited in resource-constrained settings. We assessed performance of an existing RTI risk assessment screening tool among women living with HIV (WLHIV) considering intrauterine contraceptive (IUC) use.<h4>Methods</h4>We conducted a cross-sectional analysis among WLHIV screened for ...

Safety and continued use of the levonorgestrel intrauterine system as compared with the copper intrauterine device among women living with HIV in South Africa: A randomized controlled trial.

Catherine S Todd, Heidi E Jones, Nontokozo Langwenya, Donald R Hoover, Pai-Lien Chen, Gregory Petro, Landon Myer,

BACKGROUND:Women living with HIV (WLHIV) have lower rates of contraceptive use than noninfected peers, yet concerns regarding contraceptive efficacy and interaction with antiretroviral therapy (ART) complicate counseling. Hormonal contraceptives may increase genital tract HIV viral load (gVL) and sexual transmission risk to male partners. We compared gVL, plasma VL (pVL), ... Read more >>

Impact of universal antiretroviral therapy for pregnant and postpartum women on antiretroviral therapy uptake and retention.

Elaine J Abrams, Nontokozo Langwenya, Averie Gachuhi, Allison Zerbe, Harriet Nuwagaba-Biribonwoha, Simangele Mthethwa-Hleta, Ruben Sahabo, Maia Lesosky, Velephi Okello, Landon Myer,

<h4>Objective</h4>Universal eligibility for lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women ('Option B+') has been widely adopted, but concerns remain. We tested the hypothesis that the change from CD4+-guided ART eligibility ('Option A'), to Option B+, would improve maternal ART uptake and retention.<h4>Design</h4>A stepped-wedge evaluation at 12 health facilities ...

Healthcare worker experiences with Option B+ for prevention of mother-to-child HIV transmission in eSwatini: findings from a two-year follow-up study.

Abby L DiCarlo, Averie Baird Gachuhi, Simangele Mthethwa-Hleta, Siphesihle Shongwe, Thabo Hlophe, Zachary J Peters, Allison Zerbe, Landon Myer, Nontokozo Langwenya, Velephi Okello, Ruben Sahabo, Harriet Nuwagaba-Biribonwoha, Elaine J Abrams,

<h4>Background</h4>Prevention of mother-to-child transmission (PMTCT) across sub-Saharan Africa has rapidly shifted towards Option B+, an approach in which all HIV+ pregnant and breastfeeding women initiate lifelong antiretroviral therapy (ART) independent of CD4+ count. Healthcare workers (HCW) are critical to the success of Option B+, yet little is known regarding HCW ... Read more >>

Lower genital tract cytokine profiles in South African women living with HIV: influence of mucosal sampling.

Shameem Z Jaumdally, Lindi Masson, Heidi E Jones, Smritee Dabee, Donald R Hoover, Hoyam Gamieldien, Nontokozo Langwenya, Landon Myer, Catherine S Todd, Jo-Ann S Passmore,

Measurement of cytokines in the lower female genital tract offer insight into risk for HIV infection and reproductive complications. However, few studies have systematically compared mucosal collection methods or whether collection order matters. We compared longitudinal cytokine profiles in matched genital samples collected from women living with HIV using menstrual ... Read more >>

Same-day antiretroviral therapy (ART) initiation in pregnancy is not associated with viral suppression or engagement in care: A cohort study.

Nontokozo Langwenya, Tamsin K Phillips, Kirsty Brittain, Allison Zerbe, Elaine J Abrams, Landon Myer,

INTRODUCTION:Many prevention of mother-to-child HIV transmission programmes across Africa initiate HIV-infected (HIV positive) pregnant women on lifelong antiretroviral therapy (ART) on the first day of antenatal care ("same-day" initiation). However, there are concerns that same-day initiation may limit patient preparation before starting ART and contribute to subsequent non-adherence, disengagement from ... Read more >>

Comparison of sampling methods to measure HIV RNA viral load in female genital tract secretions.

Shameem Z Jaumdally, Heidi E Jones, Donald R Hoover, Hoyam Gamieldien, Jean-Mari Kriek, Nontokozo Langwenya, Landon Myer, Jo-Ann S Passmore, Catherine S Todd,

<h4>Problem</h4>How does menstrual cup (MC) compare to other genital sampling methods for HIV RNA recovery?<h4>Method of study</h4>We compared HIV RNA levels between MC, endocervical swab (ECS), and ECS-enriched cervicovaginal lavage (eCVL) specimens in 51 HIV-positive, antiretroviral therapy-naive women at enrollment, 3 and 6 months, with order rotated by visit. Paired comparisons ... Read more >>
