BACKGROUND: The value of quantitative interferon-γ release assay results for predicting progression from Mycobacterium tuberculosis infection to active disease is unknown. We aimed to investigate the relation between QuantiFERON-TB Gold In-Tube (QFT) conversion interferon-γ values and risk of subsequent active tuberculosis disease and of QFT reversion. METHODS: We analysed data from a reported vaccine efficacy trial of the tuberculosis vaccine MVA85A in South Africa...

Background Drug-resistant tuberculosis threatens recent gains in the treatment of tuberculosis and human immunodeficiency virus (HIV) infection worldwide. A widespread epidemic of extensively drug-resistant (XDR) tuberculosis is occurring in South Africa, where cases have increased substantially since 2002. The factors driving this rapid increase have not been fully elucidated, but such knowledge is needed to guide public health interventions. Methods We conducted a prospective study involving 404 participants in KwaZulu-Natal Province, South Africa, with a diagnosis of XDR tuberculosis between 2011 and 2014...

Neil A R Gow, Mihai G Netea
Fungi cause more than a billion skin infections, more than 100 million mucosal infections, 10 million serious allergies and more than a million deaths each year. Global mortality owing to fungal infections is greater than for malaria and breast cancer and is equivalent to that owing to tuberculosis (TB) and HIV. These statistics evidence fungal infections as a major threat to human health and a major burden to healthcare budgets worldwide. Those patients who are at greatest risk of life-threatening fungal infections include those who have weakened immunity or have suffered trauma or other predisposing infections such as HIV...

BACKGROUND: The effects of antiretroviral therapy on risk of severe bacterial infections in people with high CD4 cell counts have not been well described. In this study, we aimed to quantify the effects of immediate versus deferred ART on the risk of severe bacterial infection in people with high CD4 cell counts in a preplanned analysis of the START trial. METHODS: The START trial was a randomised controlled trial in ART-naive HIV-positive patients with CD4 cell count of more than 500 cells per μL assigned to immediate ART or deferral until their CD4 cell counts were lower than 350 cells per μL...

There is experimental and clinical evidence that some exanthematous allergic drug hypersensitivity reactions are mediated by drug-specific T cells. We hypothesized that the capacity of certain drugs to directly stimulate the innate immune system may contribute to generate drug-specific T cells. Here we analyzed whether abacavir, an HIV-1 reverse transcriptase inhibitor often inducing severe delayed-type drug hypersensitivity, can trigger innate immune activation that may contribute to its allergic potential...

BACKGROUND: As sub-Saharan Africa transitions to a new era of universal antiretroviral therapy (ART), up-to-date assessments of population-level HIV RNA suppression are needed to inform interventions to optimise ART delivery. We sought to measure population viral load metrics to assess viral suppression and characterise demographic groups and geographical locations with high-level detectable viraemia in east Africa. METHODS: The Sustainable East Africa Research in Community Health (SEARCH) study is a cluster-randomised controlled trial of an HIV test-and-treat strategy in 32 rural communities in Uganda and Kenya, selected on the basis of rural setting, having an approximate population of 10 000 people, and being within the catchment area of a President's Emergency Plan for AIDS Relief-supported HIV clinic...

BACKGROUND: HIV and syphilis epidemics in men who have sex with men (MSM) continue to grow in China, despite considerable government attention. We did a literature review to synthesise key features of the HIV and syphilis epidemics and responses among MSM and transgender individuals in China. Our goal was to inform evidence-based recommendations for policy makers and program managers. METHODS: We searched Medline, EMBASE, the Cochrane Library, China National Knowledge Infrastructure, and Wanfang using the terms "MSM", "transgender", "meta-analysis", "review", and "China" for articles published in the last six years...

BACKGROUND: The Chinese government now encourages innovation, and more specifically, crowdsourcing. Crowdsourcing, the process of shifting individual tasks to a large group, might reimagine health communication, making it more people-centred. We aimed to compare the effectiveness of a crowdsourced versus social marketing condom promotion video to promote condom use. METHODS: A non-inferiority randomised controlled trial was conducted in November 2015 in China. Men who have sex with men (MSM) aged 16 years or older who reported having had sexual contact without use of a condom in the preceding 3 months were recruited through a nationwide MSM website...

BACKGROUND: In the past decade, recreational drug use has considerably increased among Chinese men who have sex with men (MSM). This increase has a great potential to worsen the scenario of the heavy burden of HIV among Chinese MSM. This study aimed to investigate the prevalence of recreational drug use, and to explore the association between poppers use and testing history for HIV or STIs, gay app use, and other sexual behaviours. METHODS: We recruited MSM who were born male and were aged 16 years or older through a nation-wide online survey in 2014...

BACKGROUND: Most men who have sex with men (MSM) in China do not publicly disclose their sexual orientation. This low rate of disclosure may affect sexual behaviours, testing for HIV or other sexually transmitted infections (STIs), and disease transmission. This study examined factors associated with overall sexual orientation disclosure and disclosure to a healthcare professional. METHODS: We did a cross-sectional online survey of MSM in China from September 23, 2014, to October 8, 2014, through three national websites...

Background The discovery of potent and broadly neutralizing antibodies (bNAbs) against human immunodeficiency virus (HIV) has made passive immunization a potential strategy for the prevention and treatment of HIV infection. We sought to determine whether passive administration of VRC01, a bNAb targeting the HIV CD4-binding site, can safely prevent or delay plasma viral rebound after the discontinuation of antiretroviral therapy (ART). Methods We conducted two open-label trials (AIDS Clinical Trials Group [ACTG] A5340 and National Institutes of Health [NIH] 15-I-0140) of the safety, side-effect profile, pharmacokinetic properties, and antiviral activity of VRC01 in persons with HIV infection who were undergoing interruption of ART...

Syphilis remains the most common congenital infection worldwide and has tremendous consequences for the mother and her developing fetus if left untreated. Recently, there has been an increase in the number of congenital syphilis cases in the United States. Thus, recognition and appropriate treatment of reproductive-age women must be a priority. Testing should be performed at initiation of prenatal care and twice during the third trimester in high-risk patients. There are 2 diagnostic algorithms available and physicians should be aware of which algorithm is utilized by their testing laboratory...

BACKGROUND: Cash transfers have been proposed as an intervention to reduce HIV-infection risk for young women in sub-Saharan Africa. However, scarce evidence is available about their effect on reducing HIV acquisition. We aimed to assess the effect of a conditional cash transfer on HIV incidence among young women in rural South Africa. METHODS: We did a phase 3, randomised controlled trial (HPTN 068) in the rural Bushbuckridge subdistrict in Mpumalanga province, South Africa...

BACKGROUND: Depression is highly prevalent in people with HIV and has consistently been associated with poor antiretroviral therapy (ART) adherence. Integrating cognitive behavioural therapy (CBT) for depression with adherence counselling using the Life-Steps approach (CBT-AD) has an emerging evidence base. The aim of this study was to test the efficacy of CBT-AD. METHODS: In this three-arm randomised controlled trial in HIV-positive adults with depression, we compared CBT-AD with information and supportive psychotherapy plus adherence counselling using the Life-Steps approach (ISP-AD), and with enhanced treatment as usual (ETAU) including Life-Steps adherence counselling only...

BACKGROUND: In Africa, up to 30% of HIV-infected patients who are clinically eligible for antiretroviral therapy (ART) do not start timely treatment. We assessed the effects of an intervention targeting prevalent health systems barriers to ART initiation on timing and completeness of treatment initiation. METHODS: In this stepped-wedge, non-blinded, cluster-randomised controlled trial, 20 clinics in southwestern Uganda were randomly assigned in groups of five clinics every 6 months to the intervention by a computerised random number generator...

BACKGROUND: An interim analysis of data from the HIV Prevention Trials Network (HPTN) 052 trial showed that antiretroviral therapy (ART) prevented more than 96% of genetically linked infections caused by human immunodeficiency virus type 1 (HIV-1) in serodiscordant couples. ART was then offered to all patients with HIV-1 infection (index participants). The study included more than 5 years of follow-up to assess the durability of such therapy for the prevention of HIV-1 transmission. METHODS: We randomly assigned 1763 index participants to receive either early or delayed ART...
