OBJECTIVE: The optimal screening frequency of sexually transmitted infections (STIs) for men who have sex with men (MSM) and transgender women (TGW) on HIV pre-exposure prophylaxis (PrEP) is unclear, with current guidelines recommending screening every three to six months. We aimed to determine the number of STIs for which treatment would have been delayed without quarterly screening. DESIGN: The United States PrEP Demonstration Project was a prospective, open-label cohort study that evaluated PrEP delivery in STI clinics in San Francisco and Miami and a community health center in Washington, DC...

OBJECTIVE: Pre-treatment HIV-drug-resistance (PDR, HIVDR) to non-nucleoside reverse transcriptase inhibitors (NNRTIs) is increasing globally. NNRTIs continue to be used as 1st-line antiretroviral therapy (ART) in some communities due to the cost of dolutegravir-based ART or dolutegravir-associated adverse events. A simplified version of the oligonucleotide ligation assay (OLA), "OLA-Simple", is a low-cost, near point-of-care assay that provides ready-to-use lyophilized reagents and reports HIVDR mutations as colored lines on lateral flow strips...

: With current antiretroviral therapy, the lifespan of newly diagnosed persons with HIV (PWH) approaches that of uninfected persons. However, metabolic abnormalities related to both the disease and the virus itself, along with comorbidities of aging, have resulted in end organ disease and organ failure as a major cause of morbidity and mortality. Solid organ transplantation is a life-saving therapy for PWH who have organ failure, and the approval of the HIV Organ Policy Equity (HOPE) Act has opened and expanded opportunities for PWH to donate and receive organs...

OBJECTIVE: Psoriasis is a T-cell-mediated inflammatory disease with genetic factors involved in its etiopathogenesis. In non-HIV populations, HLA-B*57:01 has been associated with a higher risk of psoriasis. The aim of this study was to investigate demographic and immunovirological characteristics associated with psoriasis, and to assess whether HLA-B*57:01 is associated with psoriasis among people living with HIV (PLHIV) followed in a large French multicenter Dat'AIDS cohort. METHODS: All PLHIV followed up from January 2000 to December 2018 with an available result for HLA-B*57:01 were included...

OBJECTIVE: Chronic kidney disease (CKD) with tubular injury and fibrosis occurs in HIV infection treated with certain protease inhibitor (PI)-based antiretroviral therapies. The pathophysiology is unclear. DESIGN: We hypothesized that fibrosis, mediated by platelet-derived transforming growth factor (TGF)-β1, underlies PI-associated CKD. We induced this in mice exposed to the PI ritonavir (RTV), and intervened with low-dose inhaled carbon monoxide (CO), activating erythroid 2-related factor (Nrf2)-associated anti-oxidant pathways...

BACKGROUND: Early diagnosis of HIV is important for the prevention of ongoing transmission and development of HIV-related illness. The purpose of this study is to develop an outcome indicator to monitor the progress in early HIV diagnosis. METHODS: Persons diagnosed with HIV in New York City and their first CD4 test results were used to estimate the distribution of HIV diagnosis delay, based on a CD4 count depletion model. The distribution was then used to estimate the probability of diagnosis within 1 year of HIV acquisition, which is the number of cases diagnosed in a given calendar year for which diagnosis occurred within 1 year of acquisition divided by the number of incident cases in that calendar year...

INTRODUCTION: The pathophysiology of immune activation and its mechanisms in children living with perinatally acquired HIV (PHIV) in sub-Saharan Africa has been understudied. METHODS: We enrolled 101 children living with perinatally acquired HIV (PHIV) and 96 HIV negative controls (HIV-). All participants were between 10-18 years of age with no known active infections. PHIVs were on ART with HIV-1 RNA level ≤400 copies/mL. We measured plasma and cellular markers of monocyte activation, T-cell activation (expression of CD38 and HLA-DR on CD4+ and CD8+), oxidized lipids, markers of gut integrity and fungal translocation...

BACKGROUND: HIV-associated neurocognitive disorders (HAND) persist despite the widespread implementation of combined antiretroviral therapy (ART). As people with HIV (PWH) age on ART regimens, the risk of age-related comorbidities such as Alzheimer's disease (AD) may increase. However, questions remain as to whether HIV or ART will alter such risks. Beta amyloid (Aβ) and phosphorylated-tau (p-tau) proteins are associated with AD and their levels are altered in the CSF of AD cases. METHODS: To better understand how these AD-related markers are affected by HIV-infection and ART, postmortem CSF collected from 70 well-characterized HIV+ decedents was analyzed for Aβ1-42, Aβ1-40, and p-tau levels...

OBJECTIVE: Postmortem brains of subjects diagnosed with human immunodeficiency virus-1 (HIV) associated neurocognitive disorders (HAND) exhibit loss of dendrites. However, the mechanisms by which synapses are damaged are not fully understood. DESIGN: Dendrite length and remodeling occurs via microtubules (MTs) the dynamics of which are regulated by microtubule binding proteins, including MT associated protein 2 (MAP2). The HIV protein gp120 is neurotoxic and interferes with neuronal MTs...

OBJECTIVE: Astrocytes are proposed to be a critical reservoir of HIV in the brain. However, HIV infection of astrocytes is inefficient in vitro except for cell-to-cell transmission from HIV-infected cells. Here, we explore mechanisms by which cell-free HIV bypasses entry and post-entry barriers leading to a productive infection. METHODS: HIV infection of astrocytes was investigated by a variety of techniques including transfection of CD4-expressing plasmid, treatment with lysosomotropic agents or using a transwell culture system loaded with HIV-infected lymphocytes...

OBJECTIVES: To assess the validity of self-reported HIV status, and investigate factors that influence accurate reporting of HIV-positive status, in a population tested and informed of their HIV test result. DESIGN: Prospective cohort study. METHODS: We compared self-reported HIV status to biomarker-confirmed HIV test status among participants of Karonga Health and Demographic Surveillance Site (HDSS) in rural northern Malawi. We linked information on HIV test results to subsequent self-reported HIV status, and calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for self-reported HIV status (considered as a diagnostic test)...
