AIMS: To improve RT-qPCR with an internal control and a synthetic standard curve to detect HEV in HIV coinfected patients. METHODS AND RESULTS: A single-stranded RNA (ssRNA) and a double-stranded DNA (dsDNA) synthetic curve were designed, compared to the international reference panel for HEV genotypes, and tested to quantify and detect a reference panel for HEV genotypes. The detection limit of the RNA synthetic curve (50 copies/mL) was better than the DNA synthetic curve (100 copies/mL) and the WHO standard curve (250 copies/mL)...

In countries with low tuberculosis (TB) incidence, TB is concentrated in vulnerable populations, including people living with the human immunodeficiency virus (PLHIV), who have a substantially greater risk of TB than people without HIV. We searched PubMed, EMBASE and Web of Science for studies evaluating the risk factors for latent tuberculous infection (LTBI) or active TB in PLHIV in countries with TB incidence 10 per 100 000 population. Due to the number of risk factors evaluated and heterogeneity in study designs, we present summary data and a narrative synthesis...

BACKGROUND: False positive HIV screening tests in pregnancy may lead to unnecessary interventions in labor. In 2014, the Centers for Disease Control and Prevention released a new algorithm for HIV diagnosis using a 4th generation screening test, which detects antibodies to HIV as well as p24 antigen and has a shorter window period compared with prior generations. A reactive screen requires a differentiation assay, and supplemental qualitative RNA testing is necessary for nonreactive differentiation assay...

OBJECTIVE: The activation of effector immune cells at the cervicovaginal mucosa (CVM) might influence the cervical HIV load and thus the secondary transmission; however limited information is available about the innate effector cells at CVM during HIV infection. In this study we quantified and assessed the activation of the effector immune cells at the CVM of HIV infected women with different disease outcomes: non-progressive HIV disease (LTNPs) and chronic HIV-infected (CHI) and their relationship with cervical viral shedding...

HIV-associated motor neuron disease (MND), or amyotrophic lateral sclerosis (ALS)-like syndrome associated with HIV infection, is a rare manifestation of HIV infection. HIV-associated MND has only been identified in few cases to date. We analysed two Brazilian patients with HIV infection who developed MND. The diagnosis of HIV infection was concomitant with diagnosis of MND in one patient and it occurred eight years before the MND symptoms in another patient. The manifestation of MND in our patients with HIV infection was similar to classic ALS...

Chylous ascites is an uncommon finding of triglyceride-rich lymph in the peritoneal cavity. There are a variety of reported etiologies for chylous ascites; however, the reporting of chylous ascites among AIDS/HIV-positive patients is quite uncommon. This finding as a complication of immune reconstitution inflammatory syndrome is even more unusual. Here we report a case of an HIV-positive man with a history of colonic Mycobacterium avium complex who developed chylous ascites in the setting of increasing CD4 counts and decreasing viral load, suggestive of immune reconstitution inflammatory syndrome...

To achieve epidemic control of human immunodeficiency virus (HIV) infection, sub-Saharan African countries are striving to diagnose 90% of HIV infections, initiate and retain 90% of HIV-diagnosed persons on antiretroviral therapy (ART), and achieve viral load suppression* for 90% of ART recipients (90-90-90) (1). In Eswatini (formerly Swaziland), the country with the world's highest estimated HIV prevalence (27.2%), achieving 90-90-90 depends upon improving access to early ART for men and young adults with HIV infection, two groups with low ART coverage (1-3)...

Background: The effect of depressive symptoms over time on progression through the HIV treatment cascade is complex and poorly characterized. Methods: We included participants from the Centers for AIDS Research Network of Integrated Clinic Systems Cohort who were ART-naïve, had at least one viral load and HIV appointment measure after ART initiation, and had a depressive symptom measure within 6 months of ART initiation. Recent depressive symptoms were measured using the Patient Health Questionnaire-9 (PHQ-9) and categorized using a validated cut-point (PHQ-9 > 10)...

T-20 (enfuvirtide) is the only approved viral fusion inhibitor, which is used for treatment of HIV-1 infection; however, it has relatively low antiviral activity and easily induces drug resistance. We recently reported a T-20-based lipopeptide fusion inhibitor (LP-40) showing improved anti-HIV activity (Ding et al J Virol, 2017). In this study, we designed LP-50 and LP-51 by refining the structure and function of LP-40. Two new lipopeptides showed dramatically enhanced secondary structures and binding stability and were exceptionally potent inhibitors of HIV-1, HIV-2, simian immunodeficiency virus (SIV), and simian-human chimeric virus (SHIV), with mean IC50 values at very low picomolar concentrations...

Talaromyces marneffei is the most important thermal dimorphic fungus causing systemic mycosis in Southeast Asia. We report the discovery of a novel partitivirus, Talaromyces marneffei partitivirus -1 (TmPV1). TmPV1 was detected in 7 (12.7%) of 55 clinical T. marneffei isolates. Complete genome sequencing of the seven TmPV1 isolates revealed two double-stranded RNA (dsRNA) segments encoding RNA-dependent RNA polymerase (RdRp) and capsid protein, respectively. Phylogenetic analysis showed that TmPV1 occupied a distinct clade among the members of the genus Gammapartitivirus Transmission electron microscopy confirmed the presence of isometric, nonenveloped viral particles of 30 to 45 nm in diameter, compatible with partitiviruses, in TmPV1-infected T...

BACKGROUND: The cross-sectional HIV care continuum is widely used to assess the success of HIV care programmes among populations of people with HIV and the potential for ongoing transmission. We aimed to investigate whether a longitudinal continuum, which incorporates loss to follow-up and mortality, might provide further insights about the performance of care programmes. METHODS: In this longitudinal cohort study, we included individuals who entered the UK Collaborative HIV Cohort (CHIC) study between Jan 1, 2000, and Dec 31, 2004, and were linked to the national HIV cohort database (HIV and AIDS Reporting System)...
