A meta-analysis assessing all-cause mortality in HIV- exposed uninfected compared with HIV-unexposed uninfected infants and children

Objective: Conduct a meta-analysis examining differential all-cause mortality rates between HIV-exposed uninfected (HEU) infants and children as compared with their HIV-unexposed uninfected (HUU) counterparts. Design: Meta-analysis summarizing the difference in mortality between HEU and HUU infants and children. Reviewed studies comparing children in the two groups for all-cause mortality, in any setting, from 1994 to 2016 from six databases. Methods: Meta-analyses were done 

Marginal Structural Models to Assess Delays in Second-Line HIV Treatment Initiation in South Africa

Background South African HIV treatment guidelines call for patients who fail first-line antiretroviral therapy (ART) to be switched to second-line ART, yet logistical issues, clinician decisions and patient preferences make delay in switching to second-line likely. We explore the impact of delaying second-line ART after first-line treatment failure on rates of death and virologic failure. Methods We include patients with documented virologic failure on first-line ART from an 

The High Cost of HIV-Positive Inpatient Care at an Urban Hospital in Johannesburg, South Africa

Abstract Background:  While most HIV care is provided on an outpatient basis, hospitals continue to treat serious HIV-related admissions, which is relatively resource-intensive and expensive. This study reports the primary reasons for HIV-related admission at a regional, urban hospital in Johannesburg, South Africa and estimates the associated lengths of stay and costs.  Methods and Findings: A retrospective cohort study of adult, medical admissions was conducted. Each admission was 

Performance of the Cellslide automated liquid-based cytology system amongst HIV-positive women

Abstract: Background: Many women undergoing cervical screening as part of a national South African screening programme may be positive for HIV. The performance of liquid-based cytology (LBC) on samples from HIV-positive women needs to be determined.  Objectives: The performance of the Cellslide® automated LBC system was evaluated as a possible alternative to conventional cytology in a national cervical cancer screening programme. Methods: Split samples from 348 HIV-positive women 

Mass HIV Treatment and Sex Disparities in Life Expectancy: Demographic Surveillance in Rural South Africa

Abstract Background: Women have better patient outcomes in HIV care and treatment than men in sub-Saharan Africa. We assessed--at the population level--whether and to what extent mass HIV treatment is associated with changes in sex disparities in adult life expectancy, a summary metric of survival capturing mortality across the full cascade of HIV care. We also determined sex-specific trends in HIV mortality and the distribution of HIV-related deaths in men and women prior to and at each 

Costs and Cost Effectiveness of Three Approaches for Cervical Cancer Screening among HIV-Positive Women in Johannesburg, South Africa

Abstract Background: South Africa has high rates of HIV and HPV and high incidence and mortality from cervical cancer. However, cervical cancer is largely preventable when early screening and treatment are available. We estimate the costs and cost-effectiveness of conventional cytology (Pap), visual inspection with acetic acid (VIA) and HPV DNA testing for detecting cases of CIN2+ among HIV-infected women currently taking antiretroviral treatment at a public HIV clinic in Johannesburg,

Cost-effectiveness of using the Cervex-Brush (broom) compared to the elongated spatula for collection of conventional cervical cytology samples within a high-burden HIV setting: a model-based analysis

Abstract Background: From 2010 to 2014, approximately 2 million Pap smears from HIV-infected women were submitted to the South African National Health Laboratory Services (NHLS) through the national cervical cancer screening programme. The objective of this analysis was to determine whether using the plastic Cervex brush (“broom”) would be a cost-effective approach to improve cytology specimen quality as compared to the wooden spatula used currently.  Methods: A decision analysis model 

Does Most Mortality in Patients on ART Occur in Care or After Lost to Follow-Up? Evidence From the Themba Lethu Clinic, South Africa.

Abstract In resource-limited settings, early mortality on antiretroviral therapy (ART) is approximately 10%; yet, it is unclear how much of that mortality occurs in care or after lost to follow-up. We assessed mortality rates and predictors of death among 12,222 nonpregnant ART-naive adults initiating first-line ART between April 2004 and May 2012 in South Africa, stratified by person-years in care and lost. We found 14.6% of patients died and being lost accounted for a minority of deaths 

Introducing medication abortion into public sector facilities in KwaZulu-Natal, South Africa: an operations research study

Abstract Objectives: Examine the feasibility of introducing mifepristone-misoprostol medication abortion into existing public sector surgical abortion services in KwaZulu-Natal, South Africa.  Study Design: Cohort study of women offered medication or surgical abortion in a larger medication abortion introduction study. The sample included 1167 women seeking first-trimester abortion at four public sector facilities; 923 women at ≤9 weeks' gestation were eligible for medication abortion. 

Outcomes of TB/HIV co- infected patients presenting with antituberculosis drug-induced liver injury

Abstract Background. South Africa has a significant burden of tuberculosis (TB). Anti-TB drug-induced liver injury (TB DILI) is one of the most serious adverse events that can arise from TB treatment (TBT). There are limited data on TB DILI among HIV-infected patients and those on antiretroviral therapy (ART).  Objective. To describe characteristics of HIV-infected patients presenting with TB DILI and the proportion reintroduced on standard or modified TBT after DILI. Methods. This was 

Predictive and prognostic properties of TB-LAM among HIV-positive patients initiating ART in Johannesburg, South Africa

Abstract While the diagnostic properties of the TB LAM urine assay (LAM) have been well-described, little is known about its predictive and prognostic properties at ART initiation in a routine clinic setting. We describe the predictive and prognostic properties of LAM in HIV-positive patients initiating ART at an urban hospital in Johannesburg, South Africa. Retrospective study of HIV-positive adults (>18 years) who initiated standard first-line ART between February 2012 and April 2013
