OBJECTIVE: Mild forms of HIV-associated neurocognitive disorder (HAND) remain prevalent in the combination anti-retroviral therapy (cART) era. This study's objective was to identify neuropsychological subgroups within the Multicenter AIDS Cohort Study (MACS) based on the participant-based latent structure of cognitive function and to identify factors associated with subgroups. DESIGN: The MACS is a four-site longitudinal study of the natural and treated history of HIV disease among gay and bisexual men...

OBJECTIVE: In sub-Saharan Africa, young women who engage in transactional sex (the exchange of sex for money or gifts) with a male partner show an elevated risk of prevalent HIV infection. We analyse longitudinal data to estimate the association between transactional sex and HIV incidence. DESIGN: We used longitudinal data from a cohort of 2,362 HIV negative young women (aged 13-20) enrolled in a randomized controlled trial in rural, South Africa who were followed for up to 4 visits over 6 years...

BACKGROUND: Global guidelines recommend pre-exposure prophylaxis (PrEP) use by women at risk for HIV, including during pregnancy, a period with heightened HIV risk. However, data to support safety of PrEP use during pregnancy are limited, particularly from women using PrEP throughout pregnancy. METHODS: In an open-label delivery study of PrEP integrated with ART for high risk HIV serodiscordant couples in Kenya and Uganda (the Partners Demonstration Project), women who became pregnant while using PrEP were offered the option to continue PrEP throughout pregnancy...

OBJECTIVE: Current treatments cannot completely eradicate HIV-1 owing to the presence of latently infected cells which harbor transcriptionally silent HIV-1. However, defucosylated antibodies can readily kill latently infected cells after their activation to express envelope glycoprotein (Env) through antibody-dependent cellular cytotoxicity (ADCC). We herein aimed to test a defucosylated bispecific multivalent molecule consisting of domain-antibody and single-domain CD4, LSEVh-LS-F, for its HIV-1 neutralizing activity and ADCC against the reactivated latently infected cells, compared with the non-defucosylated molecule LSEVh-LS...

OBJECTIVE: This study aims to understand the basis of continued HIV-1 transmission in Zambian and Rwandan HIV-1 discordant couples in the context of ART. DESIGN: We identified 9 Zambian and 7 Rwandan acutely-infected, epidemiologically-linked couples from government CVCT clinics where transmitting partners reported being on ART near the time of transmission. METHODS: We quantified viral load (VL) and plasma antiretroviral (ARV) drug concentrations near the time of transmission and used these as surrogate measures for adherence...

OBJECTIVE(S): Type I IFN (IFN-I) responses confer both protective and pathogenic effects in persistent virus infections. IFN-I diversity, stage of infection and tissue compartment may account for this dichotomy. The gut is a major site of early HIV-1 replication and microbial translocation, but the nature of the IFN-I response in this compartment remains unclear. DESIGN: Samples were obtained from two IRB-approved cross-sectional studies. The first study included individuals with chronic, untreated HIV-1 infection (n = 24) and age/gender balanced uninfected controls (n = 14)...

OBJECTIVE: HIV pre-exposure prophylaxis (PrEP) use may lead to higher STI incidence via behavioral risk compensation. We examined changes in sexual behaviour between baseline and six months after PrEP initiation among men who have sex with men (MSM) and transgender women (TGW). DESIGN: Prospective, open-label demonstration study at a large sexually transmitted infections (STI) clinic in Amsterdam, the Netherlands. METHODS: Participants answered questions about sexual behaviour in the preceding three months, including number of anal sex partners and frequency of anal sex with and without condom by partner type and were tested for STI...

BACKGROUND: The widespread introduction of combination antiretroviral therapy (cART) has increased survival of HIV+ patients. However, the prevalence of age-related comorbidities remains higher than that of the general population, suggesting that individuals with HIV suffer from accelerated aging. Immune activation, -senescence and inflammation could play an important role in this process. METHODS: The CIADIS (Chronic Immune Activation anD Senescence) sub-study analyzed biomarkers of activation, differentiation, and senescence of T-cells in a cellular-CIADIS weighted score, while biomarkers of inflammation were analyzed in a soluble-CIADIS weighted score using principal component analysis...

: Adolescents/young adults, and especially males, are high-risk key populations that have been systematically missed by HIV services in low-and middle-income countries (LMICs). Since these groups are also more likely to suffer injuries in LMICs, there are significant opportunities to engage these hard-to-reach persons via integrated HIV-injury programming provided during commonly sought acute/emergency care treatments of injuries. However, current facilities based HIV testing and treatment programs have failed to adequately capture these high-risk individuals...

: Among 3596 HIV-positive participants enrolled in Botswana Combination Prevention Project who self-reported no prior antiretroviral (ARV) therapy use and were tested for viral load (n = 951; 27% of all participants), 136 (14%) had HIV-1 RNA less than 400 copies/ml. ARV drugs were detected in 52 (39%) of 134 participants tested. Adjusting for undisclosed ARV use increased the overall estimate of virally suppressed individuals on ARV therapy by 1.4% from 70.2 to 71.6%.

OBJECTIVES: A Fracture risk assessment tool (FRAX®) using clinical risk factors (CRFs) alone underestimates fracture risk in HIV-infected men. Our objective was to determine whether accuracy of FRAX would be improved by considering HIV as a cause of secondary osteoporosis, and further improved with addition of DXA parameters in HIV-infected women. DESIGN: Subgroup analysis of Women's Interagency HIV Study. METHODS: We included 1148 women (900 HIV-infected and 248 uninfected) over age 40 with data to approximate FRAX CRFs and 10-year observational data for incident fragility fractures; 181 (20%) HIV-infected women had DXA data...

OBJECTIVES: Hematological abnormalities that include changes in bone marrow, such as in anemia and pancytopenia, are common among human immunodeficiency virus (HIV)-infected patients, particularly in the advanced stage of disease. Such abnormalities may be caused by a reduced bone marrow function for hematopoiesis. This aim of this study was to determine whether transcriptional gene silence can help to preserve the hosts' hematopoietic potential in addition to peripheral CD4 T cells against CCR5-tropic HIV infection...

OBJECTIVE: Worldwide, most new HIV infections occur through mucosal exposure. Immunoglobulin M (IgM) is the first antibody class generated in response to infectious agents; IgM is present in the systemic circulation and in mucosal fluids as secretory IgM. We sought to investigate for the first time the role of IgM in preventing AIDS virus acquisition in vivo. DESIGN: Recombinant polymeric monoclonal IgM was generated from the neutralizing monoclonal IgG1 antibody 33C6-IgG1, tested in vitro, and given by passive intrarectal (i...

OBJECTIVE: Despite viral suppression, HIV-associated cognitive impairment persists and may be partially due to persistent immune signaling by cells of the myeloid-lineage. Here we aimed to understand the contribution of activated microglia located in vulnerable brain regions (e.g., frontal, subcortical) of HIV-infected, virally suppressed (HIV+VS) individuals in relation to cognitive and motor function. DESIGN: 21 HIV+VS individuals underwent positron emission tomography (PET) with [C]DPA-713 to image the translocator protein 18 KDa (TSPO), a marker of microglial activation, and completed a comprehensive neuropsychological test battery...

OBJECTIVE: In HIV-infected individuals on antiretroviral therapy (ART), latent HIV is enriched in CD4 T-cells expressing immune checkpoint molecules (ICs), in particular programmed cell death-1 (PD-1). We therefore assessed the effect of blocking PD-1 on latency, both in vitro and in vivo. METHODS: HIV latency was established in vitro following co-culture of resting CD4 T-cells with myeloid dendritic cells. Expression of PD-1 was quantified by flow cytometry, and latency assessed in sorted PD-1 and PD-1 non-proliferating CD4 memory T-cells...
