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…

With only a year until 2020 – and the deadline to reach the 90-90-90 targets – South Africa is dangerously off track. Currently 7.1 million people are living with HIV in the country. New HIV infections remain high, according to the Thembisa model1 at 275 000 in 2017, higher than the 231 000…

OBJECTIVE: To examine the prevalence and magnitude of chronic lung disease (CLD) and its association with empiric anti-tuberculosis treatment (due to lack of bacteriologic confirmation) among recurrent tuberculosis (TB) survivors in a human immunodeficiency virus (HIV) prevalent…

BACKGROUND: There is a paucity of data describing autoimmune skin diseases in sub-Saharan Africa and in HIV positive cohorts. We describe the incidence of autoimmune skin diseases in public dermatology clinics in Botswana.

METHODS: New patient records…

OBJECTIVES: Vaginal dysbiosis and STIs are important drivers of the HIV epidemic and reproductive complications. These conditions remain prevalent, partly because most cases are asymptomatic. We have shown that inflammatory cytokines interleukin (IL)-1alpha, IL-1beta and…

OBJECTIVES: To determine the proportion of rifampicin-resistant tuberculosis (RR-TB) patients who accessed second-line drug susceptibility testing (SL-DST) results following introduction of the Hain technology in southern provinces, Zimbabwe.

DESIGN:

OBJECTIVES: HIV infection has been associated with an impaired lung function in high-income countries, but the association between HIV infection and pulmonary function in Sub-Saharan Africa remains unclear. This study aims to investigate the relation between HIV infection and…

In East and Southern Africa, where 5% to 10% have chronic hepatitis B virus (HBV) infection, incidence of human immunodeficiency virus (HIV) infection remains unacceptably high. This introduces challenges and opportunities for implementation of HBV care and treatment. We now describe new HIV…

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:

People living with HIV (PLHIV) are at increased risk of tuberculosis (TB). TB is also the leading opportunistic infection contributing to about one-third of deaths in this population. The World Health Organization recommends regular screening for TB in PLHIV. Those…

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…

Each year, we commemorate World Tuberculosis (TB) Day on March 24 to raise public awareness about the devastating health, social and economic consequences of TB, and to step up efforts to end the global TB epidemic. The date marks the day in 1882 when Dr Robert Koch announced that he had…

Despite advances in prevention, diagnosis and treatment of tuberculosis and human immunodeficiency virus (HIV), tuberculosis remains the leading cause of death and illness among people living with HIV. In 2015, an estimated 1.2 million of the people who developed tuberculosis disease worldwide…

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…

Background: Little up-to-date information is available about the costs of providing drug-susceptible tuberculosis (DS-TB) treatment to paediatric patients in South Africa (SA), nor have actual costs incurred at clinics been compared with costs expected from guidelines.

Background: In South Africa, roughly half of the drug-resistant TB cases diagnosed are reported to have been started on treatment. We determined the proportion of persons diagnosed with rifampicin resistant (RR-) TB who initiated treatment in Johannesburg after the introduction…

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 (…

BACKGROUND: In Sub-Saharan Africa, HIV endemic has substantially contributed to the increasing tuberculosis (TB) incidence…

BACKGROUND: In most developing economies particularly in Africa, more people are likely to die of HIV/AIDS and malaria compared to other diseases. HIV/AIDS tends to be superimposed on the long standing malaria burden particularly in sub-Saharan Africa. The detection and…

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…

WHO has published a global TB report every year since 1997. The main aim of the report is to provide a comprehensive and up-to-date assessment of the TB epidemic, and of progress in prevention, diagnosis and treatment of the disease at global, regional and country levels. This is done in the…

The purpose of this guide is to provide a resource for clinicians on the ground who manage HIV and TB clients on a daily basis. The guide presents the tools and knowledge required to ensure that clients are offered the best quality of service, and will also enable the health facility to move…

Update on antiretroviral regimens for treating and preventing HIV infection: Since 2016, WHO has recommended tenofovir disoproxil fumarate (TDF) + lamivudine (3TC) (or emtricitabine, FTC) + efavirenz (EFV) 600 mg as the preferred first- line antiretroviral therapy (ART) regimen…

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…
