INTRODUCTION: Tuberculosis (TB) continues to be a leading cause of death in Sub-Saharan Africa, including Mozambique. While diagnostic methods and…

There is evidence of increasing levels of pretreatment HIV drug resistance (PDR) in Southern Africa. We used data from two large population-based HIV surveillance studies to estimate prevalence of PDR in KwaZulu-Natal, the province with the highest HIV prevalence in South Africa. Sanger…

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…

For people who may have been exposed to HIV, knowledge is critical to making informed decisions about their future. An HIV test is a serious event with potentially serious outcomes. But no matter the result, the test provides vital information. A negative result is an opportunity to take…

The Southern African HIV Clinicians Society’s biannual conference, held in Johannesburg, South Africa, from 24-27 October 2018, focused on clinical content for HIV and TB health care workers in the region and featured a wide range of topics…

An essential first step in caring for HIV-infected children is accurate and early diagnosis of HIV, early HIV testing, prompt return of results, and rapid initiation of treatment. Survival of HIV‐infected infants depends on a robust early infant diagnosis (EID) system that allows for tracking of…

HIV drug resistance (HIVDR) poses a threat to future antiretroviral therapy success. Monitoring HIVDR patterns is of particular importance in populations such as sex workers (SWs), where documented HIV prevalence is between 34-89%, and in countries with limited therapeutic options. Currently in…

Antiretroviral therapy (ART) that enables suppression of HIV replication has been successfully rolled out at large scale to HIV-positive patients in low-income and middle-income countries. WHO guidelines for these regions define failure of ART with a lenient threshold of viraemia (HIV RNA viral…

Fungi are major contributors to the opportunistic infections that affect patients with HIV/AIDS. Systemic infections are mainly with Pneumocystis jirovecii (pneumocystosis), Cryptococcus neoformans (cryptococcosis), Histoplasma capsulatum (histoplasmosis), and 

Providing HIV testing at health facilities remains the most common approach to ensuring access to HIV treatment and prevention services for the millions of undiagnosed HIV-infected individuals in sub-Saharan Africa. We sought to explore the costs of providing these services across three southern…

The AIDSFree HIV Testing Services (HTS) Guidance Database has been updated with new guidelines from many PEPFAR priority countries. The database features HTS guidelines & policies on consent and confidentiality, testing algorithms & strategies, use of mandatory testing, quality assurance…

Hepatitis B virus (HBV)–HIV coinfections are becoming common with information on HBV genetic diversity and drug resistance still remaining elusive. To evaluate the HBV genetic diversity and drug resistance-associated mutations among drug-experienced HIV patients, the genetic analysis of the…

Rapid diagnostic tests (RDT) for HIV infection have high sensitivity and specificity, but in the setting of longstanding antiretroviral therapy (ART), can give false results that can lead to misinterpretation, confusion and inadequate management. The objective of this study was to evaluate the…

Rapid diagnostic tests (RDTs) are the primary diagnostic tools for HIV used in resource-constrained settings. Without a proper confirmation algorithm, there is concern that false-positive (FP) RDTs could result in misdiagnosis of HIV infection and inappropriate antiretroviral treatment (ART)…

This study describes the overall accuracy and performance of a serial rapid HIV testing algorithm used in community-based HIV testing in the context of a population-based household survey conducted in two sub-districts of uMgungundlovu district, KwaZulu-Natal, South Africa, against reference…

To mark the 9th IAS Conference on HIV Science, the Lancet journals have made a selection of content free that reflects some of the breadth and diversity of clinical, epidemiological, and operational HIV research produced by the tireless global HIV community. The content includes…

This second HIV drug resistance (HIVDR) report provides an update on recent population levels of HIVDR covering the period 2014–2016. The report includes data from 16 nationally representative surveys from 14 countries estimating resistance in: adults initiating ART (PDR), children younger than…

Multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis are emerging worldwide. The Green Light Committee initiative supported programmatic management of drug-resistant tuberculosis in 90 countries. We used estimates from the Preserving Effective TB Treatment Study to predict…

New strategies for HIV testing services (HTS) are needed to achieve UN 90-90-90 targets, including diagnosis of 90% of people living with HIV. Task-sharing HTS to trained lay providers may alleviate health worker shortages and better reach target groups.

We conducted a systematic review of…

Although individual HIV rapid diagnostic tests (RDTs) show good performance in evaluations conducted by WHO, reports from several African countries highlight potentially significant performance issues. Despite widespread use of RDTs for HIV diagnosis in resource-constrained settings, there has…

Tuberculosis disproportionately affects hard-to-reach populations, such as homeless people, migrants, refugees, prisoners, or drug users. These people often face challenges in accessing quality health care. We did a systematic review of the qualitative literature to identify barriers and…

Although the number of deaths worldwide from tuberculosis—a disease caused by the bacterium Mycobacterium tuberculosis—fell by 22% between 2000 and 2015, it remains humanity’s biggest infectious killer and one of the top ten causes of all deaths. The 2016 WHO Global Tuberculosis Report estimated…

The Stop TB Partnership today launched its World TB Day website which has the full spectrum of downloadable communications materials. World TB Day is…

The World Health Organization was requested by Member States to develop a global priority pathogens list (global PPL) of antibiotic-resistant bacteria to help in prioritizing the research and development (R&D) of new and effective antibiotic treatments. To date, the selection of pathogens…

South Africa has one of the highest burdens of tuberculosis and drug-resistant tuberculosis in the world. In the past decade, the number of cases of XDR tuberculosis has increased by a factor of 10, to more than 1500 cases in 2012. Compounding the tuberculosis epidemic is the concurrent epidemic…

Globally 3.9% of new and 21% of re-treatment tuberculosis (TB) cases are multidrug-resistant or rifampicin-resistant (MDR/RR), which is often interpreted as evidence that drug resistance results mainly from poor treatment adherence. This study aims to assess the respective contributions of the…

Rapid diagnostic tests (RDTs) account for more than two-thirds of malaria diagnoses in Africa. Deletions of the Plasmodium falciparum hrp2 (pfhrp2) gene cause false-negative RDT results and have never been investigated on a national level. Spread of pfhrp2-deleted 

According to the World Health Organization, South Africa ranks as one of the highest burden of TB, TB/HIV co-infection, and drug-resistant TB (DR-TB) countries. DR-TB treatment is complicated to administer and relies on the use of multiple toxic drugs, with potential for severe adverse drug…
