OBJECTIVE: HIV-infected treatment with antiretroviral drugs is one of the common causes of macrocytosis. In patients receiving highly active antiretroviral therapy (HAART), the mean corpuscular volume (MCV) can be shifted from microcytic to normocytic or macrocytic after treatment and significantly affected the thalassemia screening. This study aimed to compare MCV between thalassemia-carrier and non-thalassemia-carrier antiretroviral drug-naïve, HIV-infected, pregnant women receiving HAART...

We estimated rates and predictors of death among a community-recruited prospective cohort of 961 human immunodeficiency virus (HIV)-infected people who inject drugs in Vancouver, Canada, between 1996 and 2014. The results demonstrated significant declines in age-adjusted all-cause and HIV-related mortality rates since 2010, coincident with the scale-up of a community-wide "seek-and-treat" campaign.

BACKGROUND: The Xpert MTB/RIF (Xpert) assay offers rapid and accurate diagnosis of tuberculosis (TB) but still suffers from imperfect sensitivity. The newer Xpert MTB/RIF Ultra cartridge has shown improved sensitivity in recent field trials, but at the expense of reduced specificity. The clinical implications of switching from the existing Xpert cartridge to the Xpert Ultra cartridge in different populations remain uncertain. METHODS AND FINDINGS: We developed a Markov microsimulation model of hypothetical cohorts of 100,000 individuals undergoing diagnostic sputum evaluation with Xpert for suspected pulmonary TB, in each of 3 emblematic settings: an HIV clinic in South Africa, a public TB center in India, and an adult primary care setting in China...

OBJECTIVE: To determine the antiretroviral activity of the integrase strand transfer inhibitors (INSTIs), raltegravir, elvitegravir, dolutegravir, cabotegravir and bictegravir, against different subtypes as well as primary and acquired drug resistance mutations (DRM) in a patient-cohort infected with diverse subtypes. DESIGN: Biochemical and virological drug sensitivity analysis using patient derived HIV-1 genes and cross-sectional/longitudinal clinical study. METHODS: Assays for inhibition of 3'-end processing (IC50-3P), strand transfer (IC50-ST) and drug sensitivity (DSA) for five INSTIs were done using patient-derived integrase or gag-pol genes from subtypes A1, B, C, 01_AE and 02_AG...

OBJECTIVE: Use of Pre-Exposure Prophylaxis (PrEP) for HIV raises concerns about sexually transmitted infection (STI) incidence due to decreased condom use among men who have sex with men (MSM). This study examines whether PrEP is associated with STIs in the 12-months following PrEP prescription relative to the 12-months prior to PrEP and if STI rates are higher among PrEP users relative to individuals receiving Post-Exposure Prophylaxis (PEP). DESIGN: Retrospective cohort study including PrEP users with >12 months of follow-up before PrEP prescription and individuals receiving PEP from 2010-2015 at Clinique l'Actuel (Montréal, Canada)...

HIV-1-specific cytotoxic T cells (CTLs) play an important role in the control of HIV-1 subtype B or C infection. However, the role of CTLs in HIV-1 subtype A/E infection still remains unclear. Here we investigated the association of HLA class I alleles with clinical outcome in treatment-naïve Vietnamese infected with subtype A/E. We found that HLA-C*12:02 was significantly associated with lower pVL and higher CD4 count and that the HLA-A*29:01-B*07:05-C*15:05 haplotype was significantly associated with higher pVL and lower CD4 count as compared to individuals without these respective genotypes...

BACKGROUND: Sub-Saharan Africa is the region with the highest HIV burden. Adolescent girls and young women (AGYW) in the age range of 15 to 24 years are twice as likely as their male peers to be infected, making females in sub-Saharan Africa the most at-risk group for HIV infection. It is therefore critical to prioritize access to HIV testing, prevention, and treatment for this vulnerable population. OBJECTIVE: Using an implementation science framework, the purpose of this research protocol was to describe the approaches we propose to optimize engagement of AGYW in both the HIV prevention and care continuum and to determine the recruitment and testing strategies that identify the highest proportion of previously undiagnosed HIV infections...

BACKGROUND: The outbreak of the Ebola virus disease (EVD) in 2014 led to massive dropouts in HIV care in Guinea. Meanwhile, Médecins Sans Frontières (MSF) was implementing a six-monthly appointment spacing approach adapted locally as Rendez-vous de Six Mois (R6M) with an objective to improve retention in care. We sought to evaluate this innovative model of ART delivery in circumstances where access to healthcare is restricted. METHODS: A retrospective cohort study in 2014 of the outcome of a group of stable patients (viral load ≤1000 copies/μl) enrolled voluntarily in R6M compared with a group of stable patients continuing standard one to three monthly visits in Conakry...

The cervical microbiota composition and diversity of HIV-positive women in the postpartum period is unknown. Using a high-throughput bacterial 16S rRNA gene sequencing, we identified four community state types (CSTs). CST III (Lactobacillusdominant) and CST IV (IV-A, IV-B.1, IV-B.2; high-diversity) were found in 41% and 59% of samples, respectively. We did not find association of any CST to postpartum period (six or twelve months), HPV infection or cytology (normal or lesion). However, five bacterial genera were associated with cervical lesions (Gardnerella, Aerococcus, Schlegelella, Moryella and Bifidobacterium), with significant odds ratio (OR) of 40 (2...

The study of neighborhood disadvantage and health relies on census socioeconomic data but would benefit from reliable survey measures of factors that influence health within low income communities. The Perceptions of Neighborhood Environment Scale (PNES) was developed for use in the general U.S. population, and its measurement properties in a cohort of low-income urban women living with or at risk for HIV are described. The scale and all but one subscale have good psychometric and ecometric reliability, as well as convergent, construct, and concurrent validity, and are not collinear with household and community area income in low-income urban neighborhoods...

BACKGROUND: Several studies suggest that U.S. state-level legalization of cannabis for medical purposes may be associated with reductions in opioid use; yet its relationship with stimulant use, particularly in high-risk populations like unstably housed women, has received less attention. The purpose of this study was to estimate independent associations between medical and non-medical use of cannabis and use of stimulants and opioids among unstably housed women. METHODS: Cross-sectional data were analyzed from 245 women in the SHADOW study, a community based cohort in San Francisco, CA, in which HIV+ women were oversampled (126 HIV+ and 119 HIV-)...

BACKGROUND: Perinatally HIV-infected (PHIV+) adolescents and young adults (AYA) are at risk for sub-optimal antiretroviral therapy (ART) adherence, and mental health and substance use problems that, in HIV-infected adults, predict non-adherence. Studies on the relationship between psychiatric and substance use disorders (SUD) and adherence among PHIV+ AYA are limited, but may be important to informing evidence-based interventions to promote adherence. METHODS: Data were analyzed from three annual follow-up interviews (FU2-4, N=179) in a longitudinal study of PHIV+ AYA...

BACKGROUND: The implementation of Medicare part D on January 1, 2006 required all adults who were dually enrolled in Medicaid and Medicare (dual eligibles) to transition prescription drug coverage from Medicaid to Medicare part D. Changes in payment systems and utilization management along with the loss of Medicaid protections had the potential to disrupt medication access, with uncertain consequences for dual eligibles with human immunodeficiency virus (HIV) who rely on consistent prescription coverage to suppress their HIV viral load (VL)...

This study examined time to treatment initiation by age among a prospective cohort with drug-resistant tuberculosis (DR-TB). Participants aged 13 years or older nested within a cluster-randomized trial in 2 South African provinces were evaluated. Outcomes were treatment initiation within 5 days of DR-TB diagnosis (National Tuberculosis Program guidelines) and days from diagnosis to treatment. A total of 521 participants met inclusion criteria. Eighty-two patients (16%) met national guidelines; median time to treatment was 11 days (range = 0-180)...

OBJECTIVES: To determine the prevalence of chronic ear disease in HIV+, highly active anti-retroviral therapy (HAART)-treated children and compare this to the prevalence in healthy children of similar age living in a similar setting. INTRODUCTION: From previous clinical work in Ethiopia, we suspected that chronic middle ear disease was common both in the general pediatric population and especially among children with HIV/AIDS. Few studies have examined the prevalence of chronic ear disease in HIV + children, particularly in those treated with HAART...

The role of a 32 base pair deletion in the CCR5 gene (CCR5Δ32) in HIV-disease progression and response to combined antiretroviral therapy (cART) is well established. However, the impact of CCR5Δ32 in the long-term survival pre-cART and after cART introduction in a large cohort of HIV-infected patients is unknown. We analyzed the association of CCR5Δ32 deletion in the long-term survival of HIV-infected patients recruited between June 1981 and October 2016 (n = 1006). Clinical and epidemiological variables were recorded and CCR5Δ32 deletion was assessed by PCR and electrophoretic analysis...

Cryptococcal meningitis (CM) is mostly seen in immunocompromised patients, particularly human immunodeficiency virus (HIV)-positive patients, but CM may also occur in apparently immunocompetent individuals. Outcome analyses have been performed in such patients but, due to the high prevalence of HIV infection worldwide, CM patients today may be admitted to hospitals with unknown HIV status, particularly in underdeveloped countries. The objective of this multicenter study was to analyze all types of CM cases in an aggregate cohort to disclose unfavorable outcomes...

Background: Anti-HIV-1 broadly neutralizing antibodies (bnAbs) have been developed as potential agents for prevention of HIV-1 infection. The HIV Vaccine Trials Network and the HIV Prevention Trials Network are conducting the Antibody Mediated Prevention (AMP) trials to assess whether, and how, intravenous infusion of the anti-CD4 binding site bnAb, VRC01, prevents HIV-1 infection. These are the first test-of-concept studies to assess HIV-1 bnAb prevention efficacy in humans. Methods: The AMP trials are two parallel phase 2b HIV-1 prevention efficacy trials conducted in two cohorts: 2700 HIV-uninfected men and transgender persons who have sex with men in the United States, Peru, Brazil, and Switzerland; and 1500 HIV-uninfected sexually active women in seven countries in sub-Saharan Africa...
