OBJECTIVE: Children and adolescents with HIV infection are well-known to face a heightened risk of tuberculosis. However, the exact mortality rates and temporal trends of those with HIV-TB co-infection remain unclear. We aimed to identify the overall mortality and temporal trends within this population. METHODS: PubMed, Web of Science, and Embase were employed to search for publications reporting on the mortality rates of children and adolescents with HIV-TB co-infection from inception to March 2, 2024...

OBJECTIVE: The aim of this study was to examine outcomes of follow-up for persons with discordant fourth-generation HIV screening test results. DESIGN: A retrospective chart review. METHODS: We analyzed the electronic health record at the Medical University of South Carolina for a 10-year period spanning 2012-2022 to identify instances of discordant HIV screening test results, wherein initial antigen/antibody screening was positive, but reflex confirmatory testing for HIV-1 and HIV-2 antibodies was negative...

OBJECTIVE: To assess how antiretroviral therapy (ART) initiation during acute or early HIV infection (AEHI) affects the viral reservoir and host immune responses. DESIGN: Single-arm trial of ART initiation during AEHI at 30 sites in the Americas, Africa, and Asia. METHODS: HIV DNA was measured at week 48 of ART in 5 million CD4+ T cells by sensitive qPCR assays targeting HIV gag and pol. Peripheral blood mononuclear cells were stimulated with potential HIV T cell epitope peptide pools consisting of env, gag, nef, and pol peptides and stained for expression of CD3, CD4, CD8, and intracellular cytokines/chemokines...

BACKGROUND: IMPAACT 1077BF/FF compared the safety/efficacy of two HIV antiretroviral therapy (ART) regimens to zidovudine (ZDV) alone during pregnancy for HIV prevention. PROMISE found an increased risk of preterm delivery (<37 weeks) with antepartum triple ART (TDF/FTC/LPV+r or ZDV/3TC/LPV+r) compared to ZDV alone. We assessed the impact of preterm birth, breastfeeding and antepartum ART regimen on 24-month infant survival. METHODS: We compared HIV-free and overall survival at 24-months for liveborn infants by gestational age, time-varying breastfeeding status, and antepartum ART arm at 14 sites in Africa and India...

OBJECTIVE: : HIV treatment regimen during pregnancy was associated with preterm delivery (PTD) in the PROMISE 1077 BF trial. Systemic inflammation among pregnant women with HIV could help explain differences in PTD by treatment regimen. We assessed associations between inflammation, treatment regimen, and PTD. DESIGN/METHODS: : A nested 1:1 case-control study (N = 362) was conducted within a multi-country randomized trial comparing three HIV regimens in pregnant women: zidovudine alone, or combination antiretroviral therapy (ART) with lopinavir/ritonavir and either zidovudine or tenofovir...

OBJECTIVE: To determine how aging impacts health care utilization in persons with HIV (PWH) compared to persons without HIV (PWoH). DESIGN: Matched case-control study. METHODS: We studied Medicaid recipients in the United States, aged 18-64 years, from 2001 to 2012. We matched each of 270,074 PWH to three PWoH by baseline year, age, gender, and zip code. Outcomes were hospital and nursing home days per month (DPM). Comorbid condition groups were cardiovascular disease, diabetes, liver disease, mental health conditions, pulmonary disease, and renal disease...

OBJECTIVES: : Cognitive impairment persists in virally-suppressed people with HIV (VS-PWH) especially in higher order domains. One cortical circuit, linked to these domains, is regulated by N-acetyl-aspartyl glutamate (NAAG), the endogenous agonist of the metabotropic glutamate receptor 3. The enzyme glutamate carboxypeptidase II (GCPII) catabolizes NAAG and is upregulated in aging and disease. Inhibition of GCPII increases brain NAAG and improves learning and memory in rodent and primate models...

OBJECTIVES: To characterize the genetic diversity and drug resistance profiles of people with HIV-1 failing ART in Cape Verde (CV). DESIGN: Cross- sectional study conducted between January 2019 and December 2021 in 24 health centres on the islands of Santiago and São Vicente. METHODS: The HIV-1 pol gene was sequenced in individuals with a detectable viral load (VL). HIV-1 genetic diversity was determined by phylogenetic analysis. Drug resistance mutation patterns and resistance phenotypes were estimated using the Stanford algorithm...

BACKGROUND: Few studies have examined which subgroups of people with HIV (PWH) carry the greatest burden of internalized HIV stigma (IHS), which may be important to care provision and interventions. METHODS: PWH in the CFAR Network of Integrated Clinical Systems (CNICS) longitudinal, US-based, multisite, clinical care cohort completed tablet-based assessments during clinic visits including a 4-item, Likert scale (low 1-5 high), IHS instrument. Associations between sociodemographic characteristics and IHS scores were assessed in adjusted linear regression models...

OBJECTIVE: To evaluate the efficacy and safety of 96 weeks of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) treatment in participants switching from dolutegravir (DTG)-based therapy. DESIGN: Studies 1489 (NCT02607930) and 1490 (NCT02607956) were phase 3 randomized, double-blind, active-controlled, first-line therapy trials in people with HIV-1. After 144 weeks of DTG-based or B/F/TAF treatment, participants could enter a 96-week open-label extension (OLE) of B/F/TAF...

OBJECTIVE: To identify factors - including social determinants of health (SDOH) - that explain racial/ethnic disparities in antiretroviral therapy (ART) adherence and sustained viral suppression (SVS) among U.S. men who have sex with men (MSM) with HIV. DESIGN: We used weighted data from 2017 to 2021 cycles of the Medical Monitoring Project. METHODS: Among MSM taking ART, we calculated prevalence differences (PDs) with 95% confidence intervals (CIs) of ART adherence (100% ART adherence, past 30 days) and SVS (all viral loads in past 12 months <200 copies/ml or undetectable) for Black MSM (BMSM) and Hispanic/Latino MSM (HMSM) compared with White MSM (WMSM)...

OBJECTIVE: CCR5-tropic viruses are preferentially transmitted during perinatal HIV-1 infection. CCR5 density on CD4+ T cells likely impacts susceptibility to HIV-1 infection. DESIGN: Fifty-two mother-infant dyads were enrolled. All mothers were living with HIV-1, 27 of the infants acquired HIV-1 in utero and 25 infants remained uninfected. METHODS: CCR5 density, together with frequencies of CD4+ and CD8+ T cells expressing immune activation (CCR5, ICOS and HLA-DR) and immune checkpoint (TIGIT and PD-1) markers, were measured in whole blood from the dyads close to delivery...

OBJECTIVE: Almost 400 000 people with HIV (PWH) in the United States are over age 55 years and at risk for age-associated dementias (AAD), including Alzheimer's disease and vascular contributions to cognitive impairment and dementia (VCID). We projected the cumulative incidence and mortality associated with AAD among PWH at least 60 years in the United States compared with the general population. DESIGN/METHODS: Integrating the CEPAC and AgeD-Pol models, we simulated two cohorts of male and female individuals at least 60 years old: PWH, and general US population...

OBJECTIVE: Neurofilament light chain protein (NfL) is a marker of neuronal injury and neurodegeneration. Typically assessed in cerebrospinal fluid, recent advances have allowed this biomarker to be more easily measured in plasma. This study assesses plasma NfL in people with HIV (PWH) compared to people without HIV (PWoH), and its relationship with cognitive impairment, cardiovascular risk, and a neuroimaging metric of brain aging (brain-age gap). DESIGN: 104 PWH (HIV RNA <50 copies/mL) and 42 PWoH provided blood samples and completed a cardiovascular risk score calculator, neuroimaging and cognitive testing...

BACKGROUND AND OBJECTIVE: The risk factors of diabetes mellitus (DM) in people with HIV (PWH) may be dynamic in a life course manner. This study aimed to describe incidence of DM and investigate the trajectory of changes in risk factor associated with DM incidence over around 15 years among a statewide cohort of PWH in South Carolina (SC). DESIGN: This is a population-based cohort study. METHODS: Data were retrieved from the integrated statewide electronic health records between 2006 and 2020 in SC...
