Tuberculosis meningitis (TBM) is a frequent cause of meningitis in HIV-infected individuals, resulting in death in ~ 40% of affected patients. A severe complication of antiretroviral therapy (ART) in these patients is neurological TB-immune reconstitution inflammatory syndrome (IRIS), but its underlying cause remains poorly understood. To investigate the pathogenesis of TBM-IRIS, we performed longitudinal whole blood microarray analysis of HIV-infected TBM patients and reflected the findings at the protein level...

The prevalence of HIV-associated neurocognitive disorders (HAND) remains high despite combination antiretroviral therapy (cART). There is evidence that neural stem cells (NSCs) can migrate to sites of brain injury such as those caused by inflammation and oxidative stress, which are pathological features of HAND. Thus, reductions in NSCs may contribute to HAND pathogenesis. Since the HIV non-nucleoside reverse transcriptase inhibitor efavirenz (EFV) has previously been associated with cognitive deficits and promotion of oxidative stress pathways, we examined its effect on NSCs in vitro as well as in C57BL/6J mice...

INTRODUCTION: The World Health Organization now recommends antiretroviral therapy (ART) initiation for all HIV-infected individuals regardless of CD4 cell count or disease status. Understanding the facilitators and barriers to initiation of and adherence to ART is essential to successful scale-up of "universal" ART. METHODS: To investigate facilitators and barriers to ART initiation, we conducted 44 in-depth individual or couple interviews with 63 participants (33 participants with HIV and 30 without HIV) already enrolled in a prospective implementation study of oral antiretroviral-based prevention in Kisumu, Kenya between August and September 2014...

INTRODUCTION: South African men are less likely to get tested for HIV than women and are more likely to commence antiretroviral treatment (ART) at later stages of disease, default on treatment, and to die from AIDS compared with women. The purpose of this study was to conduct formative research into the ideational and behavioral factors that enable or create obstacles to mens' uptake of HIV counseling and testing (HCT) and ART. The study consulted men with a goal of developing a communication campaign aimed at improving the uptake of HIV testing and ART initiation among men...

BACKGROUND: Community empowerment approaches have been found to be effective in responding to HIV among female sex workers (FSWs) in South Asia and Latin America. To date, limited rigorous evaluations of these approaches have been conducted in sub-Saharan Africa. METHODS: A phase II community randomized controlled trial is being conducted in Iringa, Tanzania, to evaluate the effectiveness of a community empowerment-based combination HIV prevention model (Project Shikamana) among a stratified sample of HIV-infected and HIV-uninfected FSWs...

BACKGROUND: For HIV-serodiscordant couples, integrated delivery of antiretroviral therapy (ART) for HIV-positive partners and time-limited pre-exposure prophylaxis (PrEP) for negative partners virtually eliminates HIV transmission. Standardized messaging, sensitive to the barriers and motivators to HIV treatment and prevention, is needed for widespread scale-up of this approach. METHODS: Within the Partners Demonstration Project, a prospective interventional project among 1013 serodiscordant couples in Kenya and Uganda, we offered ART to eligible HIV-positive partners and PrEP to HIV-negative partners before ART initiation and through the HIV-positive partner's first 6 months of ART use...

BACKGROUND: As test and treat rolls out, effective interventions are needed to address the determinants of outcomes across the HIV treatment continuum and ensure that people infected with HIV are promptly tested, initiate treatment early, adhere to treatment, and are virally suppressed. Communication approaches offer viable options for promoting relevant behaviors across the continuum. CONCEPTUAL FRAMEWORK: This article introduces a conceptual framework, which can guide the development of effective health communication interventions and activities that aim to impact behaviors across the HIV treatment continuum in low- and medium-income countries...

INTRODUCTION: Female sex workers (FSW) in sub-Saharan Africa have a higher prevalence of HIV than other women of reproductive age. Social, legal, and structural barriers influence their access to care. Little is known about the HIV diagnosis and care cascade in most countries in southern Africa. We aimed to describe the HIV diagnosis and care cascade among FSW in Zimbabwe. METHODS: We conducted cross-sectional respondent driven sampling (RDS) surveys of FSW in 14 sites across Zimbabwe as the baseline for a cluster-randomised controlled trial investigating a combination HIV prevention and care package...

Human immunodeficiency virus (HIV) infection has become a treatable chronic disease with near-normal life expectancy when patients receive antiretroviral therapy (ART). Family physicians and other primary care clinicians commonly provide long-term comprehensive care for persons with HIV infection. This article describes the scope of initial care, including obtaining a thorough history; physical examination for HIV-associated manifestations; attention to HIV-specific immunization schedules; routine and HIV-specific laboratory evaluation; and ensuring standard health care maintenance to prevent HIV- and non-HIV-related morbidity and mortality...

Early mortality after initiation of antiretroviral therapy (ART) occurs in 9-39% of patients in sub-Saharan Africa. A significant proportion of deaths are attributable to tuberculosis (TB). Low baseline CD4 T-cell count and low body mass index (BMI) are strongly associated with early mortality. We hypothesized that initiation of ART concurrent with presumptive anti-TB chemotherapy in high-risk patients would reduce mortality within the first 6 months by treating unrecognized TB. From October 2011 to December 2012, ART-naive, smear-negative participants with a CD4 T-cell count < 50 cells/μL and BMI < 18 kg/m(2) were randomly assigned to undergo either empiric four-drug anti-TB treatment followed 2 weeks later by efavirenz-based ART (N = 23) (ART + TB) or ART only (N = 20)...

BACKGROUND: Multiple viruses co-infect the male genital tract, influencing each other's replication and perhaps affecting HIV pathogenesis and disease progression. METHODS: This study included 453 longitudinal seminal samples from 195 HIV-infected men from the San Diego Primary Infection Cohort and 67 seminal samples from HIV-negative healthy controls. Seminal HIV RNA and DNA from seven human herpesviruses (HHV) were measured by RT-PCR. Longitudinal shedding rates were determined by Kaplan-Meier survival analysis...

BACKGROUND: The numbers of HIV-infected women initiating antiretroviral therapy (ART) in pregnancy are increasing rapidly with global policy changes. There are widespread concerns about ART adherence during pregnancy and postpartum but few data on viral suppression (VS) over time in these populations. METHODS: We followed a cohort of 523 women in Cape Town, South Africa initiating ART in pregnancy (once daily tenofovir 300mg, emtracitabine 200mg and efavirenz 600mg) and achieving VS (<50 copies/mL)...

BACKGROUND: Although early presentation to HIV-care is essential to ensure timely initiation of antiretroviral therapy, recent studies have shown that especially migrants present to HIV-care at a later stage of HIV-infection. Currently, thirty percent of all newly diagnosed HIV cases in Germany originate from abroad. So far it is unknown, which specific migrant groups in Germany are particularly at risk for late presentation to HIV-care. METHODS: We used data from the Clinical Surveillance of HIV Disease (ClinSurv) cohort, a multi-centre observational cohort (01/01/1999 and 31/07/2013) and included treatment-naïve patients with valid information on country of origin and date of enrolment...

BACKGROUND: Timely and enduring access to antiretroviral therapy (ART) by HIV-infected individuals has been shown to substantially reduce HIV transmission risk, HIV-related morbidity and mortality. However, there is evidence that in addition to limited supply of antiretrovirals (ARVs) and linkage to ART in many low-income countries, HIV+ persons often encounter barriers in accessing ART-related services even in contexts where these services are freely available. In Ghana, limited research evidence exists regarding the barriers HIV+ persons already linked to ART face...

INTRODUCTION: People living with HIV (PLWH) need to adhere to antiretroviral therapy (ART) to achieve optimal health. One reason for ART nonadherence is HIV-related stigma. OBJECTIVES: We aimed to examine whether HIV treatment self-efficacy (an intrapersonal mechanism) mediates the stigma-adherence association. We also examined whether self-efficacy and the concern about being seen while taking HIV medication (an interpersonal mechanism) are parallel mediators independent of each other...

BACKGROUND: This study compared time to virologic suppression and rebound between Indigenous and non-Indigenous individuals living with HIV in Canada initiating combination antiretroviral therapy (cART). METHODS: Data were from the Canadian Observational Cohort collaboration; 8 studies of treatment-naïve persons with HIV initiating cART after 1/1/2000. Fine and Gray models were used to estimate the effect of ethnicity on 1) time to virologic suppression (two consecutive viral loads (VLs) <50 copies/mL at least three months apart) after adjusting for the competing risk of death and 2) time until virologic rebound (two consecutive VLs >200 copies/mL at least three months apart) following suppression...
