Increasing numbers of people living with HIV (PLHIV) in sub-Saharan Africa are experiencing failure of first-line antiretroviral therapy and transitioning onto second-line regimens. However, there is a dearth of research on their treatment experiences. We conducted in-…

BACKGROUND: Pregnant and post-partum adolescent girls and young women (AGYW) living with HIV in sub-Saharan Africa experience inferior outcomes along the prevention of mother-to-child transmission of HIV (PMTCT) cascade compared to their adult counterparts. Yet, despite this…

BACKGROUND: Poor retention in the prevention of women in prevention of vertical transmission programs remains a formidable common setback in elimination of HIV/AIDS. It creates new problems such as poor health outcomes and increased incidence of vertical transmission of HIV.…

In 2017, tuberculosis caused an estimated 1·6 million deaths, including 300 000 deaths among people with HIV, and surpassed HIV/AIDS to become the leading infectious cause of mortality worldwide. Approximately 36% of tuberculosis cases each year (around 3·5 million cases) are not diagnosed or…

BACKGROUND: The Prevention of Mother to Child Transmission (PMTCT) of HIV programme in Zimbabwe has had remarkable success despite the country's economic challenges. The aim of this study was to explore the challenges faced by breastfeeding mothers on the PMTCT programme.

BACKGROUND: Expanded HIV prevention options are needed to increase uptake of HIV prevention among women, especially in generalized epidemics. As the dapivirine vaginal ring moves forward through regulatory review and open-label extension studies, the potential public health…

More adolescents and young adults living with HIV are surviving into adulthood. As a result they must transition from pediatric health services to HIV self-management and adult care. This change is particularly important as many young people have poor adherence to treatment, leading to low rates…

Increasing numbers of people living with HIV (PLHIV) in sub-Saharan Africa are experiencing failure of first-line antiretroviral therapy and transitioning onto second-line regimens. However, there is a dearth of research on their treatment experiences. We conducted in-depth interviews with 43…

Contraceptive adherence during acute and recent HIV-1 infection is important to maternal and child health given the elevated risk of vertical HIV-1 transmission and additional complications of pregnancy. Injectable contraception (IC) is the most common non-barrier modern contraception method…

BACKGROUND: Linear growth retardation is the most dominant nutritional problem globally. We aimed to describe linear growth trajectory among infants under 2 years of age using the WHO growth velocity standards.

METHOD: This was a prospective cohort study…

Antimicrobial drug resistance is a serious health hazard driven by overuse. Administration of antimicrobial drugs to HIV-exposed, uninfected infants, a population that is growing and at high risk for infection, is poorly studied. We therefore analyzed factors associated with antibacterial drug…

Despite public health interventions targeting sex workers in an attempt to increase condom use, HIV still remains a significant health issue for those involved in the sex industry in many countries. In this paper, we analyse data collected as part of an ethnographic study of sex work in Soweto,…

BACKGROUND: Mother-to-child transmission of HIV-1 occurs in a minority of HIV-infected mother-infant pairs, even without any interventions. The mechanisms that protect the majority of HIV-exposed infants from infection are unclear. T regulatory cells (Treg) have important…

BACKGROUND: WHO recommends that HIV infected women receive antiretroviral therapy (ART) minimally during pregnancy and breastfeeding ("Option B"), or ideally throughout their lives regardless of clinical stage ("Option B+") (Coovadia et al., Lancet 379:221-228, 2012). Although…

BACKGROUND: This observational study describes implementation of HIV retesting of HIV-negative women in prevention of mother-to-child transmission (PMTCT) services in Zambia.

METHODS: Uptake of retesting and PMTCT services were compared across age,…

This study investigated perinatal depressive symptoms among HIV-infected women enrolled in a cluster-randomized, controlled trial in South Africa. Women (n = 1370) attending 12 community health centers were consecutively enrolled in a two-phase (phase 1 = without a male partner, phase 2 = with a…

Objectives: The objective of this study was to investigate the causes and covariates of late antenatal care access in South Africa.

Methods: A cross-sectional study was conducted, interviewing 221 women at four public-sector labour wards in Cape Town,…

BACKGROUND: The GeneXpert MTB/RIF Assay (Xpert(R)) is known to be a feasible, effective and a hopeful tool for rapid tuberculosis (TB) diagnosis and treatment. However, little is known about the time delay caused by initial negative sputum smear microscopy (NSSM), but…

BACKGROUND: Subclinical tuberculosis is an asymptomatic disease phase with important relevance to persons living with HIV. We describe the prevalence, clinical characteristics, and risk of mortality for HIV-infected adults with subclinical tuberculosis.

METHODS…

BACKGROUND: Xpert MTB/RIF, the most widely used automated nucleic acid amplification test for tuberculosis, is available in more than 130 countries. Although diagnostic accuracy is well documented, anticipated improvements in patient outcomes have not been clearly identified. We…

Background: Since 2010, the World Health Organization recommends lifelong antiretroviral treatment for all women living with HIV, and exclusive breastfeeding for six-months followed by breastfeeding until 24-months for all HIV positive mothers. Nevertheless, many mothers living…

Background: Drug resistance is a challenge for the global control of tuberculosis. We examined mortality in patients with tuberculosis from high-burden countries, according to concordance or discordance of results from drug susceptibility testing done locally and in a reference…

The cascade of care is a model for evaluating patient retention across sequential stages of care required to achieve a successful treatment outcome. This approach was first used to evaluate HIV care and has since been applied to other diseases. The tuberculosis (TB) community has only recently…

The emergence and expansion of the multidrug-resistant tuberculosis epidemic is a threat to the global control of tuberculosis. Multidrug-resistant tuberculosis is the result of the selection of resistance-conferring mutations during inadequate antituberculosis treatment. However, HIV has a…

Introduction: Treatment success rates of rifampicin resistant (RR)/multi-drug resistant (MDR) tuberculosis (TB) in South Africa range from 43–48%, falling short of the World Health Organization’s target of ≥75%. We present rates and assess predictors of attrition by 12 months on…

Objective: We describe baseline characteristics, time to treatment initiation and interim patient outcomes at a decentralized, outpatient treatment site for rifampicin-resistant TB (RR-TB).

Methods: Prospective observational cohort study of RR-TB…

Update on recommendations on antiretroviral regimens for treating and preventing HIV infection: In 2016, WHO published the consolidated guidelines on the use of antiretroviral (ARV) drugs for treating and preventing HIV infection and recommended tenofovir disoproxil fumarate (…

The Partnership for HIV-Free Survival (PHFS) was designed to use basic quality improvement practices to reduce mother-to-child transmission of HIV and increase child survival through improvements in (1) antiretroviral therapy uptake and retention among HIV-positive pregnant women and mothers, (2…
