Background Food insecurity and undernutrition are related but distinct concepts contributing to poor HIV and tuberculosis outcomes. Pathways linking them with immunologic profile, which may relate to clinical outcomes, remain understudied. Methods We analyzed data from a cohort study of 165 ART-naïve adults with advanced HIV and newly diagnosed tuberculosis in Botswana from 2009-2013. 29 plasma biomarkers were measured pre-ART and four weeks post-ART initiation. We used principal components analysis (PCA) and multivariable linear regression models to assess relationships between immunological profiles and food insecurity (based on the Household Food Insecurity Access Scale), undernutrition (Body Mass Index < 18.5 kg/m2), and clinical outcomes. Results PCA identified 5 principal components (PCs) with eigenvalues >1. After adjustment, food insecurity was associated with PC3 pre-ART (0.19 per increased category of severity, 95% CI 0.02 to 0.36) and post-ART (0.24, 95% CI 0.07 to 0.41). PC3 was driven by higher levels of IFN-α, IFN-γ, IL-12p40, VEGF, IL-1α, and IL-8, and decreased concentrations of IL-3. Undernutrition was associated with PC5 post-ART (0.49, 95% CI 0.16 to 0.82). PC5 was driven by higher levels of IL-8, MIP-1α, IL-6, and IL-10, and decreased concentrations in IP-10 and IFN-α. Post-ART PC3 (4.3 percentage point increased risk per increased score of 1, 95% CI 0.3 to 8.9) and post-ART PC5 (4.8, 95% CI 0.6 to 8.9) were associated with death in adjusted models. Discussion We identified two distinct immunologic profiles associated with food insecurity, undernutrition, and clinical outcomes in patients with advanced HIV and TB. Different pathophysiologic processes may link food insecurity and undernutrition with poor outcomes in this vulnerable patient population. Future studies should assess the impact of improving food access and intake on immune function and clinical outcomes. Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.

Background. Anal sex remains the greatest HIV transmission risk for men who have sex with men and carries substantial population attributable risk among women. Despite a growing array of HIV pre-exposure prophylaxis (PrEP) options, rectal microbicides remain desirable as on demand, non-systemic PrEP. Rectal microbicide product development for PrEP requires understanding the spatiotemporal distribution of HIV infectious elements in the rectosigmoid to optimize formulation development. Setting. Outpatient setting with healthy research participants. Methods. Six healthy men underwent simulated receptive anal sex with an artificial phallus fitted with a triple lumen catheter in the urethral position. To simulate ejaculation of HIV-infected semen, autologous seminal plasma laden with autologous blood lymphocytes from apheresis labeled with 111Indium-oxine (cell-associated) and 99mTechnetium-sulfur colloid (cell-free) as HIV surrogates were injected into the rectal lumen through the phallic urethra. Spatiotemporal distribution of each radioisotope was assessed using SPECT/CT over eight hours. Analysis of radiolabel distribution used a flexible principal curve algorithm to quantitatively estimate rectal lumen distribution. Results. Cell-free and cell-associated HIV surrogates distributed to a maximal distance of 15 and 16 cm, respectively, from the anorectal junction (∼19 and ∼20 cm from the anal verge), with a maximal signal intensity located 6 and 7 cm, respectively. There were no significant differences in any distribution parameters between cell-free and cell-associated HIV surrogate. Conclusions. Cell-free and cell-associated HIV surrogate distribution in the rectosigmoid can be quantified with spatiotemporal pharmacokinetic methods. These results describe the ideal luminal target distribution to guide rectal microbicide development. Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.

Introduction Adolescents living with HIV (ALH) have poorer adherence to antiretroviral therapy (ART) than adults. Many ALH in sub-Saharan Africa (SSA) are enrolled in boarding schools where stigma is pervasive and may impact adherence. Methods We collected sociodemographic data, school information, medical history, and viral load (VL) data from ALH age 14-19 in 25 HIV clinics in 3 counties in Kenya. Using generalized estimating equations, we compared ART adherence in ALH attending day and boarding schools. Results Of 880 ALH, 798 (91%) were enrolled in school, of whom 189 (24%) were in boarding schools. Of those in school, median age was 16 (IQR: 15, 18), 55% were female, 78% had a parent as a primary caregiver, and 74% were on DTG-based ART. Median age at ART initiation was 6 years (IQR 3, 10). Overall, 227 (29%) ALH self-reported missing ART when school was in session (40% in boarding and 25% in day school). After adjusting for sociodemographic and HIV care characteristics, ALH in boarding schools were significantly more likely to self-report missing ART than those in day schools (adjusted Prevalence Ratio (aPR): 1.47, 95% CI 1.18, 1.83, p=0.001). Among 194 ALH, only 60% had undetectable (

Background: Switching to the 2-drug regimen dolutegravir/lamivudine demonstrated durable non-inferior efficacy vs continuing 3- or 4-drug tenofovir alafenamide–based regimens for maintaining virologic suppression in people with HIV-1 through Week 144 in TANGO. Setting: 134 centers, 10 countries. Methods: Adults with HIV-1 RNA 6 months and no history of virologic failure were randomized to switch from stable tenofovir alafenamide–based regimens to dolutegravir/lamivudine on Day 1 (early-switch group) for 196 weeks. Those randomized to continue tenofovir alafenamide–based regimens on Day 1 who maintained virologic suppression at Week 144 switched to dolutegravir/lamivudine at Week 148 (late-switch group). Efficacy, safety, and tolerability (including weight and biomarker changes) of dolutegravir/lamivudine in early-switch and late-switch groups were assessed through Week 196. Results: Overall, 369 participants switched to dolutegravir/lamivudine on Day 1 (early-switch) and 298 switched at Week 148 (late-switch). In the early-switch group, 83% (306/369) maintained virologic suppression through Year 4, and 3% (11/369) reported new adverse events between Weeks 144 and 196. The late-switch group at Week 196 and early-switch group at Week 48 had comparable proportions with virologic suppression (93% each) and similar safety profiles. No late-switch participants and 1 early-switch participant met confirmed virologic withdrawal criteria through Week 196, with no resistance-associated mutations observed. Treatment continued to be well tolerated long-term. Conclusion: Switching from tenofovir alafenamide–based regimens to dolutegravir/lamivudine showed durable efficacy, high barrier to resistance, and good tolerability through 4 years. These results support dolutegravir/lamivudine as a robust treatment for maintaining virologic suppression. Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.

Background: Long-acting (LA) antiretrovirals may provide meaningful benefit to people who use drugs and people experiencing homelessness (PEH) who face disproportionate structural and psychosocial barriers in adhering to daily oral HIV antiretroviral therapy (ART) or pre-exposure prophylaxis (PrEP), but their use in these populations has not been studied. Setting: The Maria X. Martinez Health Resource Center is a low-barrier (e.g., no appointment) community-based clinic serving San Francisco PEH. Methods: A multidisciplinary care model with robust monitoring and outreach support was developed to provide LA-ART and LA-PrEP to eligible patients experiencing difficulties adhering to oral antiretrovirals. Feasibility was assessed by evaluating rates of HIV viremia and on-time injections among patients receiving LA antiretrovirals over the first 24 months of program implementation. Results: Between November 2021 and November 2023, 33 patients initiated LA-ART or LA-PrEP (median age, 37 years; 27% transgender/non-binary; 73% non-White; 27% street homeless; 52% sheltered homeless; 30% with opioid use disorder; 82% with methamphetamine use disorder). Among 18 patients with HIV, 14 initiated LA-ART injections with detectable viremia (median CD4 count, 340 cells/mm3; mean log10 viral load, 3.53; standard deviation [SD], 1.62), eight had never previously been virally suppressed, and all but one achieved or maintained virologic suppression (mean, 9.67 months; SD, 8.30). Among 15 LA-PrEP patients, all remained HIV-negative (mean, 4.73 months; SD, 2.89). Of 224 injections administered total, 8% were delayed >7 days. Discussion: The implementation of LA antiretrovirals is feasible in low-barrier, highly supportive clinical settings serving vulnerable PEH. Expansion of such programs will be critical to Ending the HIV Epidemic. Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.

Background: Late diagnosis of HIV infection is a major global problem. In Turkiye, only 41% - 50% of people living with HIV (PLWH) are diagnosed, suggesting that many opportunities for HIV testing might be missed. Setting: The aim of this study is to determine the missed testing opportunities for HIV in healthcare settings in Turkiye and the predictors for missed opportunities (MOs). Methods: The study included patients with a new HIV diagnosis, presenting to care between January 2018 and December 2020. They were given a verbal questionnaire face to face, by a telephone call or an online meeting for visits to a healthcare setting within the year prior to their diagnosis. Electronic medical records were also examined. Results: The sample included 198 patients with at least one visit to any healthcare setting, with a total of 1677 visits. Patients had an indication for HIV testing in 51.3% (861/1677) of the visits; an HIV test was not offered in 77.9% (671/861) and was considered a MO. The highest number of MOs was in emergency departments (EDs) (59.8%) (180/301).The most common reason for visiting was constitutional symptoms and indicator conditions (ICs) (55.4%) (929/1677).

There is mounting evidence that HIV infection is a risk factor for severe presentations of COVID-19. We hypothesized that the persistent immune activation associated with chronic HIV infection contributes to worsened outcomes during acute COVID-19. The goals of this study were to provide an in-depth analysis of immune response to acute COVID-19 and investigate relationships between immune responses and clinical outcomes in an unvaccinated, sex and race-matched cohort of people with HIV (PWH, n=20) and people without HIV (PWOH, n=41). There is mounting evidence that HIV infection is a risk factor for severe presentations of COVID-19. We hypothesized that the persistent immune activation associated with chronic HIV infection contributes to worsened outcomes during acute COVID-19. The goals of this study were to provide an in-depth analysis of immune response to acute COVID-19 and investigate relationships between immune responses and clinical outcomes in an unvaccinated, sex and race-matched cohort of people with HIV (PWH, n=20) and people without HIV (PWOH, n=41). We performed flow cytometric analyses on peripheral blood mononuclear cells from PWH and PWOH experiencing acute COVID-19 (≤ 21 days post-symptom onset). PWH were younger (median 52 vs 65 years) and had milder COVID-19 (40% vs 88% hospitalized) compared to PWOH. Flow cytometry panels included surface markers for immune cell populations, activation and exhaustion surface markers (with and without SARS-CoV-2-specific antigen stimulation), and intracellular cytokine staining. We observed that PWH had increased expression of activation (e.g., CD137, OX40) and exhaustion (e.g., PD1, TIGIT) markers as compared to PWOH during acute COVID-19. When analyzing the impact of COVID-19 severity, we found that hospitalized PWH had lower non-classical (CD16+) monocyte frequencies, decreased expression of TIM3 on CD4+ T cells, and increased expression of PDL1 and CD69 on CD8+ T cells. Our findings demonstrate that PWH have increased immune activation and exhaustion as compared to a cohort of predominately older, hospitalized PWOH and raises questions on how chronic immune activation impacts acute disease and the development of post-acute sequelae.

Background: Re-engaging people with HIV (PWH) who are newly out-of-care remains challenging. Data-to-care (D2C) is a potential strategy to re-engage such individuals. Methods: A prospective randomized controlled trial compared a D2C strategy using a disease intervention specialist (DIS) vs standard-of-care (SOC) where 23 HIV clinics in 3 counties in Connecticut could re-engage clients using existing methods. Using a data reconciliation process to confirm being newly out-of-care, 655 participants were randomized to DIS (N=333) or SOC (N=322). HIV care continuum outcomes included re-engagement at 90 days, retention in care and viral suppression (VS) by 12 months. Multivariable regression models were used to assess factors predictive of attaining HIV care continuum outcomes. Results: Participants randomized to DIS were more likely to be re-engaged at 90 days (aOR=1.42, p=0.045). Independent predictors of re-engagement at 90 days were: age>40 years (aOR=1.84, p=0.012) and peri-natal HIV risk category (aOR=3.19, p=0.030). Predictors of retention at 12 months included: re-engagement at 90 days (aOR=10.31, p

Introduction For people living with HIV/AIDS, care is commonly delivered through Differentiated Service Delivery (DSD). Although people with multidrug-resistant tuberculosis (MDR-TB) and HIV/AIDS experience severe treatment associated challenges, there is no DSD model to support their treatment. In this study, we defined patterns of medication adherence and characterized longitudinal barriers to inform development of an MDR-TB/HIV DSD framework. Methods Adults with MDR-TB and HIV initiating bedaquiline (BDQ) and receiving antiretroviral therapy (ART) in KwaZulu-Natal, South Africa, were enrolled and followed through the end of MDR-TB treatment. Electronic dose monitoring devices (EDM) measured BDQ and ART adherence. Longitudinal focus groups were conducted and transcripts analyzed thematically to describe discrete treatment stage-specific and cross-cutting treatment challenges. Results 283 participants were enrolled and followed through treatment completion (median 17.8 months [IQR 16.5–20.2]). Thirteen focus groups were conducted. Most participants (82.7%, 234/283) maintained high adherence (mean BDQ adherence 95.3%; mean ART adherence 85.5%), but an adherence-challenged subpopulation with

Objectives: Critically ill patients with tuberculosis carry high mortality. Identification of factors associated with mortality in critically ill tuberculosis patients may enable focused treatment. Data Sources: An extensive literature search of PubMed (MEDLINE), Embase, the Cochrane Library, and Google Scholar was performed using Medical Subject Headings terms “tuberculosis,” “critical care,” “critical care outcome,” and “ICU.” We aimed to identify factors affecting mortality in critically ill tuberculosis patients. Study Selection: All the studies comparing factors affecting mortality between survivors and nonsurvivors in critically ill tuberculosis patients were included. The database search yielded a total of 3017 records, of which 17 studies were included in the meta-analysis. Data Extraction: Data were collected including the name of the author, year and country of publication, duration of the study, number of patients studied, type of tuberculosis, patient demography, smoking history, laboratory parameters, comorbidities, the requirement for mechanical ventilation, duration of ventilation, ICU and hospital length of stay (LOS), type of lung involvement, complications, and outcomes. Data Synthesis: The major factors that contributed to mortality in critically ill tuberculosis patients were age, platelet count, albumin, C-reactive protein (CRP), the requirement and duration of invasive mechanical ventilation, Pao2/Fio2 ratio, presence of acute respiratory distress syndrome, shock, hospital-acquired infections, renal replacement therapy, and ICU and hospital LOS. Conclusions: Patient age, platelet count, albumin and CRP levels, the requirement and duration of invasive mechanical ventilation, Pao2/Fio2 ratio, hospital-acquired infections, renal replacement therapy, and ICU LOS were variables associated with mortality.

Abstract As use of HIV integrase strand transfer inhibitors (INSTI) increases and formulations are being developed for maintenance therapies and chemoprophylaxis, assessing virus suppression under INSTI-based regimens in prevention-relevant biologic compartments, such as the male genital tract, is timely. We used cell-source marker virion immunocapture to examine amplification of particle RNA then assessed the phylogenetic relatedness of seminal and blood viral sequences from men with HIV who were prescribed INSTI-based regimens. Seminal plasma immunocaptures yielded amplifiable virion RNA from 13/24 (54%) men, and the sequences were primarily associated with markers indicative of macrophage and resident dendritic cell sources. Genetic distances were greatest (>2%) between seminal virions and circulating proviruses, pointing to ongoing low-level expression from tissue-resident cells. While the low levels in semen predict an improbable likelihood of transmission, viruses with large genetic distances are expressed under potent INSTI therapy and have implications for determining epidemiologic linkages if adherence is suboptimal.

Abstract Background The histone deacetylase inhibitor vorinostat (VOR) can reverse human immunodeficiency virus type 1 (HIV-1) latency in vivo and allow T cells to clear infected cells in vitro. HIV-specific T cells (HXTCs) can be expanded ex vivo and have been safely administered to people with HIV (PWH) on antiretroviral therapy.Methods Six PWH received infusions of 2 × 107 HXTCs/m² with VOR 400 mg, and 3 PWH received infusions of 10 × 107 HXTCs/m² with VOR. The frequency of persistent HIV by multiple assays including quantitative viral outgrowth assay (QVOA) of resting CD4+ T cells was measured before and after study therapy.Results VOR and HXTCs were safe, and biomarkers of serial VOR effect were detected, but enhanced antiviral activity in circulating cells was not evident. After 2 × 107 HXTCs/m² with VOR, 1 of 6 PWH exhibited a decrease in QVOA, and all 3 PWH exhibited such declines after 10 × 107 HXTCs/m² and VOR. However, most declines did not exceed the 6-fold threshold needed to definitively attribute decline to the study intervention.Conclusions These modest effects provide support for the strategy of HIV latency reversal and reservoir clearance, but more effective interventions are needed to yield the profound depletion of persistent HIV likely to yield clinical benefit.Clinical Trials Registration.

by Edward Muteesasira, Davis Akampumuza, Dismus Abaho, Lillian Nuwasasira, Edward Kumakech Background Intimate partner violence (IPV) disproportionately affects married women living with HIV (MWLHIV), resulting in undesirable human rights, socio-economic, mental, maternal, and child health consequences. Community Support systems against Violence (CoSaV) are widely available and promising public and voluntary resources for the prevention and mitigation of IPV but are poorly investigated. We set out to identify the predictors for the utilization of the CoSaV among the MWLHIV. Methods This was a quantitative cross-sectional study conducted among 424 consecutively sampled MWLHIV attending the Antiretroviral Therapy (ART) clinic at Kabale Regional Referral Hospital in southwestern Uganda in April 2021. Using an interviewer-administered questionnaire, data were collected on the participant’s socio-demographic characteristics, exposure to IPV, awareness about the CoSaV, perceptions about the quality, accessibility and challenges in accessing the CoSaV and the utilization. Modified Poisson regression model was used to identify the predictors for the utilization of CoSaV using the Statistical Package for Social Sciences (SPSS) version 23.0. Results The mean age of the 424 participants in the study was 39.5 ± 10.2 years. More than half of the participants 51.9% (220/424) reported exposure to any IPV. Utilization of any CoSaV was found to be above average at 58.3% among the participants. The formal support (police, local government leaders, health workers and counselors) were more frequently utilized compared to the informal support (family, relatives and friends). Utilization of any CoSaV was higher among the women who were aware of the CoSaV and also those who were exposed to violence. Accessibility was identified as an independent predictor for utilization of any CoSaV. Conclusions Intimate partner violence (IPV) was prevalent among MWLHIV in southwestern Uganda. However, the utilization of any CoSaV was suboptimal. The formal CoSaV were more frequently utilized than the informal support systems. Accessibility was an independent predictor for utilization of any CoSaV. There is need to improve access in order to increase the utilization of the CoSaV and contribute to the attainment of sustainable development goal 5.2.1 and end violence against women.

by Sohini Paul, Anupam Sharma, Radhika Dayal, Mahika Mehta, Sudeshna Maitra, Kuhika Seth, Monal Nagrath, Sowmya Ramesh, Niranjan Saggurti Limited evidence is available on the vulnerability of Adolescent Girls and Young Women (AGYW) to sexual risk behaviour and STI/HIV. Though there are almost no statistics available on vulnerability, related literature suggests that AGYW have low awareness about sexual risk behaviour/ transmission and the prevalence of STI/HIV, making them vulnerable. We conducted a rapid review of peer-reviewed studies addressing transmission network, prevalence, incidence awareness, common determinants of sexual risk behaviour/STI/HIV, health-seeking behaviour and existing interventions addressing the situation among AGYW (age 15–24) to inform the evidence gap in this crucial area of research. We registered the study in PROSPERO (CRD42023403713). We developed detailed inclusion/exclusion criteria, searched JSTOR, PubMed, Google Scholar, Science Direct and Population Council Knowledge Commons databases and followed the guidance from Cochrane Rapid Review to develop the rapid review. We also searched the bibliography of the included studies. We included the English language peer-reviewed quantitative, qualitative, mixed method studies published from Jan 1 2000 to Mar 31 2023. Six reviewers extracted data, and the seventh reviewer independently assessed the quality. Ninety-six studies met the inclusion criteria. We used descriptive statistics and narrative synthesis methods for data analysis. We also conducted a Risk of Bias Assessment (RoB) to check the quality of the included studies. Inadequate literature was found on the transmission network. Prevalence and awareness of STI/HIV are low among AGYW. However, Female Sex Workers, sex-trafficked women or drug users in this age group suffer more. Age, education, income, relationship dynamics with spouses/partners, multiple partners, and substance use are crucial in determining STI/HIV. Traditional sources of health seeking are more popular than formal sources because of social stigma. Mass media campaigns, community mobilization programs, and life skills training programs increase awareness about HIV, condom use and self-efficacy. The inclusion of only English language studies and not conducting meta-analysis because of high heterogeneity are some of the limitations of the study.

ObjectivesTo assess the prevalence of depressive symptoms and associated factors among people living with HIV (PLWH) who were current cigarette smokers and receiving treatment at HIV outpatient clinics (OPCs) in Vietnam. DesignA cross-sectional survey of smokers living with HIV. SettingThe study was carried out in 13 HIV OPCs located in Ha Noi, Vietnam. ParticipantsThe study included 527 PLWH aged 18 and above who were smokers and were receiving treatment at HIV OPCs. Outcome measuresThe study used the Centre for Epidemiology Scale for Depression to assess depressive symptoms. The associations between depressive symptoms, tobacco dependence and other characteristics were explored using bivariate and Poisson regression analyses. ResultsThe prevalence of depressive symptoms among smokers living with HIV was 38.3%. HIV-positive smokers who were female (prevalence ratio, PR 1.51, 95% CI 1.02 to 2.22), unmarried (PR 2.06, 95% CI 1.54 to 2.76), had a higher level of tobacco dependence (PR 1.06, 95% CI 1.01 to 1.11) and reported their health as fair or poor (PR 1.66, 95% CI 1.22 to 2.26) were more likely to have depression symptoms compared with HIV-positive smokers who were male, married, had a lower level of tobacco dependence and self-reported their health as good, very good or excellent. ConclusionThe prevalence of depressive symptoms among smokers receiving HIV care at HIV OPCs was high. Both depression and tobacco use screening and treatment should be included as part of ongoing care treatment plans at HIV OPCs.

Abstract Background The World Health Organization endorsed Truenat MTB rapid molecular assay in 2020 and recommended additional in-country evaluation studies before uptake. We evaluated the accuracy and operational feasibility of Truenat MTB assay (Truenat) in comparison with GeneXpert Ultra and culture. Methods In a cross-sectional study of 250 presumptive TB patients, participants were requested to provide a sputum sample on the day of their visit to the clinic. The sputum sample was homogenized and a portion was tested using GeneXpert Ultra as per the routine standard procedure and the other portion was tested using Truenat assay at the clinic laboratory. The second sample portion was processed for Concentrated Fluorescent smear Microscopy (CFM), LJ, and MGIT cultures. Truenat sensitivity and specificity were compared to GeneXpert Ultra and culture. Test performance characteristics and operational feasibility assessment data through interview of the study laboratory staff were also collected and summarized as proportions and percentages. Results Of the 250 participants recruited in the study, the sensitivity and specificity of Truenat was n/N (%, 95%CI); 66/82 (80.5, 70.2–88.4) and 156/159 (98.1, 94.5–99.6) when compared with Ultra, 50/64 (89.3, 66.0-87.4) and 166/180 (92.2, 87.2–95.6) when compared with LJ, 58/71 (81.7,70.7–89.8) and 131/138 (94.9, 89.8–97.9) when compared to MGIT culture and 59/73 (80.8, 69.9–89.1) and 159/169 (94.1,89.3–97.1) when compared to LJ and/or MGIT culture. The sensitivity of Truenat was lower, 14/23 (60.9, 40.6–82.8) among smear-negative compared to 45/50 (90.0, 78.1–96.6) among smear-positive participants but not different by HIV status. There were no special training needs especially among laboratory personnel with previous GeneXpert /molecular test experience, 19/242 (7.8%) error/invalid, and 12 (17,4%) uninterpretable/indeterminate results mainly for rifampicin resistance determination. However, there were 3 (3.5%) of GeneXpert Ultra indeterminate results. Conclusion Among presumptive TB patients in Uganda, the Truenat assay has high sensitivity and specificity. The Truenat assay has acceptable operational feasibility attributes when compared with the GeneXpert Assay.

Abstract Background People with HIV (PWH) have an increased risk of cardiovascular disease (CVD). Cardiac magnetic resonance (CMR) has documented higher myocardial fibrosis, inflammation and steatosis in PWH, but studies have mostly relied on healthy volunteers as comparators and focused on men.Methods We investigated the associations of HIV and HIV-specific factors with CMR phenotypes in female participants enrolled in the Women’s Interagency HIV Study’s New York and San Francisco sites. Primary phenotypes included myocardial native (n) T1 (fibro-inflammation), extracellular volume fraction (ECV, fibrosis) and triglyceride content (steatosis). Associations were evaluated with multivariable linear regression, and results pooled or meta-analyzed across centers.Results Among 261 women with HIV (WWH, total n = 362), 76.2% had undetectable viremia at CMR. For the 82.8% receiving continuous antiretroviral therapy (ART) in the preceding 5 years, adherence was 51.7%, and 71.3% failed to achieve persistent viral suppression (42.2% with peak viral load

Abstract Background Unlike influenza, information on the burden of human metapneumovirus (HMPV) as a cause of hospitalizations in adults with acute respiratory illness (ARI) is limited.Methods We compared the population-based incidence, seasonality, and clinical characteristics of these two viral infections among adults aged 20 years and over with ARI hospitalisations in Auckland, New Zealand, during 2012-2015 through the Southern Hemisphere Influenza Vaccine Effectiveness Research and Surveillance (SHIVERS) project.Results Of the 14,139 ARI hospitalisations, 276 (4.3%) of 6484 tested positive for HMPV and 1342 (19.1%) of 7027 tested positive for influenza. Crude rates of 9.8 (95% CI: 8.7-11.0) HMPV and 47.6 (95% CI: 45.1-50.1) influenza-associated ARI hospitalisations were estimated for every 100,000 adult residents annually. The highest rates for both viruses were in those aged 80 years or older, of Māori or Pacific ethnicity, or living in low socioeconomic status (SES) areas. HMPV infections were more common than influenza in those with chronic medical conditions.Conclusions Although HMPV infections accounted for fewer hospitalisations than influenza in adults aged 20 years and over, HMPV-associated ARI hospitalisation rates were higher than influenza in older adults, Maori and Pacific people and those of low SES. This highlighted a need for vaccine/antiviral development.

ObjectivesSexual and gender minority (SGM) populations in sub-Saharan Africa (SSA) are disproportionately impacted by HIV and often face multiple HIV-related stigmas. Addressing these stigmas could reduce SGM HIV vulnerability but little is known about how the stigmas operate and intersect. Intersectional stigma offers a lens for understanding the experiences of stigmatised populations and refers to the synergistic negative health effects of various systems of oppression on individuals with multiple stigmatised identities, behaviours or conditions. This review aims to (1) assess how often and in what ways an intersectional lens is applied in HIV-related stigma research on SGM populations in SSA and (2) understand how intersectional stigma impacts HIV risk in these populations. DesignScoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. Data sourcesPublic health and regional databases were searched in 2020 and 2022. Eligibility criteriaArticles in French and English on HIV-related stigma and HIV outcomes among men who have sex with men, women who have sex with women and/or transgender individuals in SSA. Data extraction and synthesisArticles were screened and extracted twice and categorised by use of an intersectional approach. Study designs and stigma types were described quantitatively and findings on intersectional stigma were thematically analysed. ResultsOf 173 articles on HIV-related stigma among SGM in SSA included in this review, 21 articles (12%) applied an intersectional lens. The most common intersectional stigmas investigated were HIV and same-sex attraction/behaviour stigma and HIV, same-sex attraction/behaviour and gender non-conformity stigma. Intersectional stigma drivers, facilitators and manifestations were identified across individual, interpersonal, institutional and societal socioecological levels. Intersectional stigma impacts HIV vulnerability by reducing HIV prevention and treatment service uptake, worsening mental health and increasing exposure to HIV risk factors. ConclusionIntersectional approaches are gaining traction in stigma research among SGM in SSA. Future research should prioritise quantitative and mixed methods investigations, diverse populations and intervention evaluation.

by Abraham Teka Ajema, Yilkal Simachew, Meiraf Daniel Meshesha, Taye Gari Objectives To assess the incidence and predictors of time to Tuberculosis (TB) development among Human Immunodeficiency Virus (HIV) positive patients attending follow-up care in health facilities of Hawassa, Ethiopia. Methods We conducted a retrospective cohort study from April 1–30, 2023. A total of 422 participants were selected using a simple random sampling method. Data was collected from the medical records of patients enrolled between January 1, 2018 –December 31, 2022, using the Kobo toolbox. We used Statistical Package for Social Studies (SPSS) version 26.0 for data analysis. To estimate the duration of TB-free survival, we applied the Kaplan-Meier survival function and fitted Cox proportional hazard models to identify the predictors of time to TB development. Adjusted hazard ratios (AHR) with 95% confidence intervals were calculated and statistical significance was declared at a P-value of 0.05. Results The overall incidence rate of TB among HIV-positive patients was 6.26 (95% CI: 4.79–8.17) per 100 person-years (PYs). Patients who did not complete TB Preventive Therapy (TPT) were more likely to have TB than those who did (AHR = 6.2, 95% CI: 2.34–16.34). In comparison to those who began antiretroviral therapy (ART) within a week, those who began after a week of linkage had a lower risk of TB development (AHR = 0.44, 95% CI: 0.21–0.89). Patients who received ART for six to twelve months (AHR = 0.18, 95% CI: 0.05–0.61) and for twelve months or longer (AHR = 0.004, 95% CI: 0.001–0.02) exhibited a decreased risk of TB development in comparison to those who had ART for less than six months. Conclusion The incidence of TB among HIV-positive patients is still high. To alleviate this burden, special attention should be given to regimen optimization and provision of adherence support for better completion of TPT, sufficient patient preparation, thorough clinical evaluation for major (Opportunistic Infections) OIs prior to starting ART, and ensuring retention on ART.

OBJECTIVES: To describe clinical, management, and outcome features of critically ill patients admitted to ICUs and high-dependency units (HDUs) in Kenya. DESIGN: Prospective registry-based observational study. SETTING: Three HDUs and eight ICUs in Kenya. PATIENTS: Consecutive adult patients admitted between January 2021 and June 2022. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Data were entered in a cloud-based platform using a common data model. Study endpoints included case-mix variables, management features, and patient-centered outcomes. Patients with COVID-19 were reported separately. Of the 3892 of 4546 patients without COVID-19, 2445 patients (62.8%) were from HDUs, and 1447 patients (37.2%) were from ICUs. Patients had a median age of 53 years (interquartile range [IQR] 38–68), with HDU patients being older but with a lower severity (Acute Physiology and Chronic Health Evaluation II 6 [3–9] in HDUs vs. 12 [7–17] in ICUs; p < 0.001). One in four patients was postoperative with 604 (63.4%) receiving emergency surgery. Readmission rate was 4.8%. Hypertension and diabetes were prevalent comorbidities, with a 4.0% HIV/AIDS rate. Invasive mechanical ventilation was applied in 3.4% in HDUs versus 47.6% in ICUs (p < 0.001), with a duration of 7 days (IQR 3–21). There was a similar use of renal replacement therapy (4.0% vs. 4.7%; p < 0.001). Vasopressor use was infrequent while half of patients received antibiotics. Average length of stay was 2 days (IQR 1–5). Crude HDU mortality rate was 6.5% in HDUs versus 30.5% in the ICUs (p < 0.001). Of the 654 COVID-19 admissions, most were admitted in ICUs (72.3%) with a 33.2% mortality. CONCLUSIONS: We provide the first multicenter observational cohort study from an African ICU National Registry. Distinct management features and outcomes characterize HDU from ICU patients.

PurposeThe PRESTIGIO Registry was established in 2017 to collect clinical, virological and immunological monitoring data from people living with HIV (PLWH) with documented four-class drug resistance (4DR). Key research purposes include the evaluation of residual susceptibility to specific antiretrovirals and the validation of treatment and monitoring strategies in this population. ParticipantsThe PRESTIGIO Registry collects annual plasma and peripheral blood mononuclear cell samples and demographic, clinical, virological, treatment and laboratory data from PLWH followed at 39 Italian clinical centres and characterised by intermediate-to-high genotypic resistance to ≥1 nucleoside reverse transcriptase inhibitors, ≥1 non-nucleoside reverse transcriptase inhibitors, ≥1 protease inhibitors, plus either intermediate-to-high genotypic resistance to ≥1 integrase strand transfer inhibitors (INSTIs) or history of virological failure to an INSTI-containing regimen. To date, 229 people have been recorded in the cohort. Most of the data are collected from the date of the first evidence of 4DR (baseline), with some prebaseline information obtained retrospectively. Samples are collected from the date of enrollment in the registry. Findings to dateThe open-ended cohort has been used to assess (1) prognosis in terms of survival or development of AIDS-related or non-AIDS-related clinical events; (2) long-term efficacy and safety of different antiretroviral regimens and (3) virological and immunological factors predictive of clinical outcome and treatment efficacy, especially through analysis of plasma and cell samples. Future plansThe registry can provide new knowledge on how to implement an integrated approach to study PLWH with documented resistance to the four main antiretroviral classes, a population with a limited number of individuals characterised by a high degree of frailty and complexity in therapeutic management. Given the scheduled annual updates of PLWH data, the researchers who collaborate in the registry can send study proposals at any time to the steering committee of the registry, which evaluates every 3 months whether the research studies can be conducted on data and biosamples from the registry and whether they are aimed at a better understanding of a specific health condition, the emergence of comorbidities or the effect of potential treatments or experimental drugs that may have an impact on disease progression and quality of life. Finally, the research studies should aim to be inclusive, innovative and in touch with the communities and society as a whole. Trial registration numberNCT04098315.

IntroductionNamibia is a high tuberculosis (TB)-burden country with an estimated incidence of 460/100 000 (around 12 000 cases) per year. Approximately 4.5% of new cases and 7.9% of previously treated TB cases are multidrug resistant (MDR) and 47% of patients with MDR-TB are HIV coinfected. Published data suggest a clustering of MDR-TB transmission in specific areas. Identifying transmission clusters is key to implementing high-yield and cost-effective interventions. This includes knowing the yield of finding TB cases in high-transmission zones (eg, community hotspots, hospitals or households) to deliver community-based interventions. We aim to identify such transmission zones for enhanced case finding and evaluate the effectiveness of this approach. Methods and analysisH3TB is an observational cross-sectional study evaluating MDR-TB active case finding strategies. Sputum samples from MDR-TB cases in three regions of Namibia will be evaluated by whole genome sequencing (WGS) in addition to routine sputum investigations (Xpert MTB/RIF, culture and drug susceptibility testing). We will collect information on household contacts, use of community spaces and geographical map intersections between participants, synthesising these data to identify transmission hotspots. We will look at the feasibility, acceptability, yield and cost of case finding strategies in these hotspots, and in households of patients with MDR-TB and visitors of hospitalised patients with MDR-TB. A compartmental transmission dynamic model will be constructed to evaluate the impact and cost-effectiveness of the strategies if scaled. Ethics and disseminationEthics approval was obtained. Participants will give informed consent. H3TB will capitalise on a partnership with the Ministry of Health and Social Services to follow up individuals diagnosed with MDR-TB and integrate WGS data with innovative contact network mapping, to allow enhanced case finding. Study data will contribute towards a systems approach to TB control. Equally important, it will serve as a role model for similar studies in other high-incidence settings.

Abstract 20–41% of the world\'s population is either transiently or permanently colonized by the Gram-positive bacterium, Staphylococcus aureus. In 2017, the CDC designated methicillin resistant S. aureus (MRSA) as a serious threat, reporting ∼300 000 cases of MRSA-associated hospitalizations annually, resulting in over 19 000 deaths, surpassing that of HIV in the United States. S. aureus is a proficient biofilm-forming organism, which rapidly acquires resistance to antibiotics, most commonly methicillin (MRSA).This review focuses on a large group of (>30) S. aureus adhesins, either surface-associated or secreted that are designed to specifically bind to 15 or more of the proteins that form key components of the human extracellular matrix (hECM). Importantly, this includes hECM proteins that are pivotal to the homeostasis of almost every tissue environment (collagen (skin), proteoglycans (lung), hemoglobin (blood), elastin, laminin, fibrinogen, fibronectin, and fibrin (multiple organs). These adhesins offer S. aureus the potential to establish an infection in every sterile tissue niche. These infections often endure repeated immune onslaught, developing into chronic, biofilm-associated conditions that are tolerant to ∼1000 times the clinically prescribed dose of antibiotics. Depending on the infection and the immune response, this allows S. aureus to seamlessly transition from colonizer to pathogen by subtly manipulating the host against itself while providing the time and stealth that it requires to establish and persist as a biofilm. This is a comprehensive discussion of the interaction between S. aureus biofilms and the hECM. We provide particular focus on the role of these interactions in pathogenesis and consequently the clinical implications for the prevention and treatment of S. aureus biofilm infections.

Abstract Background Pre-diabetes is associated with proteinuria, a risk factor for chronic kidney disease. While people living with HIV (PWH) have a higher risk of proteinuria than people without HIV (PWOH), it is unknown whether incident proteinuria differs by HIV serostatus among pre-diabetic persons.Methods Urine protein-to-creatinine ratio (PCR) was measured at semi-annual visits among men in the Multicenter AIDS Cohort Study since April 2006. Men with pre-DM on or after April 2006 and no prevalent proteinuria or use of anti-diabetic medications were included. Pre-diabetes was defined as fasting glucose (FG) of 100-125 mg/dL confirmed within a year by a repeat FG or hemoglobin A1c 5.7–6.4%. Incident proteinuria was defined as PCR > 200 mg/g, confirmed within a year. We used Poisson regression models to determine whether incident proteinuria in participants with pre-diabetes differed by HIV serostatus and, among PWH, whether HIV-specific factors were related to incident proteinuria.Results Between 2006 and 2019, among 1276 men with pre-diabetes, 128/613 PWH (21%) and 50/663 PWOH (8%) developed proteinuria over a median 10-year follow-up. After multivariable adjustment, the incidence of proteinuria in PWH with pre-diabetes was 3.3 times [95% CI: 2.3–4.8 times] greater than in PWOH (p

Abstract Background Cryptococcal meningitis causes substantial mortality in high-HIV prevalence African countries despite advances in disease management and increasing antiretroviral therapy coverage. Reliable diagnosis of cryptococcal meningitis is cheap and more accessible than other indicators of AHD burden such as CD4 testing or investigation for disseminated tuberculosis; therefore, monitoring cryptococcal meningitis incidence has the potential to serve as a valuable metric of HIV programmatic success.Methods Botswana national meningitis surveillance data from 2015 to 2022 were obtained from electronic health records. All electronic laboratory records from cerebrospinal fluid samples analysed within government healthcare facilities in Botswana were extracted from a central online repository. Adjustments for missing data were made through triangulation with prospective cohort study datasets. Cryptococcal meningitis case frequency was enumerated using a case definition and incidence calculated using national census data.Results A total of 1,744 episodes of cryptococcal meningitis were identified; incidence declined from 15.0 (95% CI 13.4-16.7) cases/100,000 person-years in 2015 to 7.4 (95% CI 6.4-8.6) cases/100,000 person-years in 2022. However, the rate of decline slowed following the introduction of universal treatment in 2016. The highest incidence was observed in men and individuals aged 40-44. The proportion of cases diagnosed through cryptococcal antigen testing increased from 35.5% to 86.3%.Conclusion Cryptococcal meningitis incidence has decreased in Botswana following expansion of ART coverage but persists at a stubbornly high incidence. Most cases are now diagnosed through the cheap and easy-to-use cryptococcal antigen test highlighting the potential of using cryptococcal meningitis as key metric of programme success in the Treat All era.

by Abere Woretaw Azagew, Hailemichael Kindie Abate, Yohannes Mulu Ferede, Chilot Kassa Mekonnen Background cute kidney injury(AKI) is a rapid loss of the kidney’s excretory function, resulting in an accumulation of end products of nitrogen metabolism. The causes of AKI in HIV-positive patients are not well investigated, but it may be associated with antiretroviral drug side effects and HIV itself. Even though there were studies that reported the prevalence of AKI among HIV-positive patients in Africa, their findings were inconsistent across the studies. Methods We searched on PubMed, Embas, Ebsco, OVID, Cochrane Library, and other supplementary search engines, including Google and Google Scholar. Articles published upto July 2023 were included in this review study. The quality of the study was assessed using the Newcastle-Ottawa Scale for cross-sectional, case-control, and cohort studies. The data were extracted using a Microsoft Excel spreadsheet and exported to Stata version 14 for analysis. A random effect meta-analysis model was used to estimate the pooled prevalence of AKI among HIV-positive patients. Heterogeneity was evaluated using Cochrane Q statistics and I squared (I2). Furthermore, the graphic asymmetric test of the funnel plot and/or Egger’s tests were computed to detect publication bias. Sensitivity analysis was computed to see the effect of a single study on the summary effects. To treat the publication bias, a trim and fill analysis was carried out. The protocol of this review has been registered in an international database, the Prospective Register of Systematic Reviews (PROSPERO),with reference number CRD42023446078. Results A total of twenty-four original articles comprising 7913HIV-positive patients were included in the study. The pooled prevalence of AKI among HI-positive patients was found to be 23.35% (95% CI: 18.14–28.56%, I2 = 97.7%, p-value

Abstract In Lusaka, Zambia, we introduced liver fine needle aspiration (FNA) into a research cohort of adults with treatment-naïve chronic hepatitis B virus (HBV) infection, with and without HIV coinfection, as well as with acute HBV infection. Over 117 enrollment and 47 longitudinal FNAs (at 1 year follow-up), we established participant acceptability and safety. We also demonstrated the quality of the material through single cell RNA sequencing of selected enrollment FNAs, which revealed a range of immune cells. This approach can drive new insights into HBV immunology, informing cure strategies, and can improve our understanding of HBV natural history in Africa.

by Julia Blaauw, Jessica Chikwana, David Chaima, Stanley Khoswe, Lyson Samikwa, Isabelle de Vries, Wieger Voskuijl Background Undernutrition and malnutrition in children in low- and middle-income countries contribute to high mortality rates. Stunting, a prevalent form of malnutrition, is associated with educational and productivity losses. Environmental enteric dysfunction (EED) and human immunodeficiency virus (HIV) infection worsen these conditions. This study seeks to investigate the presence of enteropathy using EED fecal biomarkers in HIV-infected children who are stable on antiretroviral therapy (ART) across various nutritional statuses. By understanding the interplay between EED, HIV, and nutritional status, this study aims to provide insights that can inform targeted interventions to optimize nutritional outcomes in HIV infected children. Methods/Principal findings This study evaluated the levels of alpha-1-antitrypsin, calprotectin and myeloperoxidase in frozen fecal samples from 61 HIV infected (mean age 9.16 ±3.08 years) and 31 HIV uninfected (6.65 ±3.41 years) children in Malawi. Anthropometric measurements and clinical data were collected. The height-for-age z-score (-1.66 vs -1.27, p = 0.040) and BMI-for-age z-score (-0.36 vs 0.01, p = 0.037) were lower in HIV infected children. Enzyme-linked immunosorbent assays were used to measure biomarker concentrations. Statistical tests were applied to compare biomarker levels based on HIV status and anthropometric parameters. Myeloperoxidase, alpha-1-antitrypsin, and calprotectin concentrations did not differ between HIV infected and HIV uninfected children of different age groups. In HIV infected children from 5–15 years, there is no difference in biomarker concentration between the stunted and non-stunted groups. Conclusion/Significance Our study found a higher prevalence of stunting in HIV infected children compared to uninfected children, but no significant differences in biomarker concentrations. This suggests no causal relationship between enteropathy and stunting in HIV infected children. These results contribute to the understanding of growth impairment in HIV infected children and emphasize the need for further research, particularly a longitudinal, biopsy-controlled study.

by Thi Vu, Jasmine Manalel, Kate Nyhan, Katie Wang, Joan Monin Introduction The population of women aged 50 years and older living with HIV is increasing. Older women face unique challenges in the prevention and management of HIV; however, they are often under engaged in HIV/AIDS research. One such challenge is gender-based stigma, which can be manifested through harmful gendered stereotypes, discrimination, prejudice, and sexism that could potentially hinder HIV care engagement among this population. We propose a scoping review to identify and synthesize evidence pertaining to how experiences of gender-based stigma impacts HIV prevention and care among older women. Materials and methods We will use the framework by Arksey and O’Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) to conduct this scoping review. We will search MEDLINE/PubMed, Web of Science, PsycINFO, CINAHL and Scopus for empirical literature published between January 1981 and the date of search commencement. Supplementary screening will be conducted using backwards citation chaining of the final list of included full-text articles. Two reviewers will independently screen all titles and abstracts for articles that meet the predetermined inclusion criteria. Two reviewers will also screen full-text articles and chart data using a standardized data collection form. Results We will synthesize the findings through tables, charts, and narrative summaries. We will also identify gaps in the current literature and provide recommendations for future research. Findings will be shared at conferences and submitted to a peer-reviewed publication. Discussion To our knowledge, this will be the first scoping review to examine gender-based stigma in relation to HIV prevention and care among older women. We anticipate that our results will be of interest to older women living with HIV, healthcare providers, policy makers, and community activists working to improve quality of life and care experiences for older women living with HIV.

Objective: This study investigated the association of plasma microRNAs before and during antiretroviral therapy (ART) with poor CD4+ T-cell recovery during the first year of ART. Design: MicroRNAs were retrospectively measured in stored plasma samples from people with HIV (PWH) in sub-Saharan Africa who were enrolled in a longitudinal multicountry cohort and who had plasma viral-load less than 50 copies/ml after 12 months of ART. Methods: First, the levels of 179 microRNAs were screened in a subset of participants from the lowest and highest tertiles of CD4+ T-cell recovery (ΔCD4) (N = 12 each). Next, 11 discordant microRNAs, were validated in 113 participants (lowest tertile ΔCD4: n = 61, highest tertile ΔCD4: n = 52). For discordant microRNAs in the validation, a pathway analysis was conducted. Lastly, we compared microRNA levels of PWH to HIV-negative controls. Results: Poor CD4+ T-cell recovery was associated with higher levels of hsa-miR-199a-3p and hsa-miR-200c-3p before ART, and of hsa-miR-17-5p and hsa-miR-501-3p during ART. Signaling by VEGF and MET, and RNA polymerase II transcription pathways were identified as possible targets of hsa-miR-199a-3p, hsa-200c-3p, and hsa-miR-17-5p. Compared with HIV-negative controls, we observed lower hsa-miR-326, hsa-miR-497-5p, and hsa-miR-501-3p levels before and during ART in all PWH, and higher hsa-miR-199a-3p and hsa-miR-200c-3p levels before ART in all PWH, and during ART in PWH with poor CD4+ T-cell recovery only. Conclusion: These findings add to the understanding of pathways involved in persistent HIV-induced immune dysregulation during suppressive ART. Copyright © 2024 The Author(s).

IntroductionSexually diverse Muslim men are seen to be at a higher risk for HIV and other sexually transmitted infections due to their limited access to sexual healthcare services. We outline a protocol to conduct a scoping review of research on the barriers that may impede these men’s access to sexual healthcare. Methods and analysisTo conduct this scoping review, we will follow the methodological framework developed by Arksey and O’Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses’ extension for scoping reviews. To classify the barriers to sexual healthcare, we will employ Bronfenbrenner’s socioecological model as a conceptual framework. We will conduct a literature search via Medline, Embase and Global Health (OVID); Scopus; CINAHL on EBSCOhost along with several other EBSCOhost databases (Academic Search Complete, Canadian Reference Centre, Alternative Press Index, Family & Society Studies Worldwide, Social Work Abstracts) and Google Scholar, published until November 2023. Journal articles, published in the English language, describing quantitative and qualitative research on sexual healthcare access barriers for sexually diverse Muslim men will be included in the review. Commentaries and correspondences, along with grey literature including research reports and conference abstracts, as well as studies that do not include men with the Muslim faith, will be considered ineligible. Following screening of titles and abstracts, we will conduct a full-text screening to determine the final number of studies to be included in the review. A Microsoft Excel spreadsheet will be used to extract study characteristics, and information on sexual healthcare access barriers will be classified according to the socioecological model’s core concepts. Ethics and disseminationOur review does not require ethics approval. We will disseminate the review findings through peer-reviewed academic journals, seminars and conference presentations.

IntroductionThe measure of sexual orientation and gender identity (SOGI) data in electronic health records (EHR) has been critical for addressing health disparities and inequalities, especially for HIV care. Given that gender and sexual minorities (eg, transgender, men who have sex with men and intersex) are key groups in people living with HIV (PLWH), SOGI data can facilitate a more accurate understanding about the HIV outcomes (eg, viral suppression) among this key group and then lead to tailored therapeutic services. The two-step SOGI collection method as an emerging gender measurement can be used to measure SOGI status in medical settings. Using the statewide cohort of PLWH in South Carolina (SC), this project aims to: (1) integrate statewide PLWH cohort data with their birth certificate data to evaluate SOGI measurements from multiple EHR sources; and (2) examine differences in viral suppression based on SOGI measurements. Methods and analysisOur EHR database includes several HIV data sources with patients’ gender information, such as SC Department of Health and Environmental Control Centre (DHEC), Health Sciences South Carolina (HSSC) and Prisma as well as birth certificate data to retrieve the sex at birth. The SC Enhanced HIV/AIDS Reporting System (e-HARS) from DHEC will provide longitudinal viral load information to define a variety of viral suppression status. Datasources like the SC office of Revenue and Fiscal Affairs (RFA) will extract longitudinal EHR clinical data of all PLWH in SC from multiple health systems; obtain data from other state agencies and link the patient-level data with county-level data from multiple publicly available data sources. Ethics and disseminationThe study was approved by the Institutional Review Board at the University of South Carolina (Pro00129906) as a Non-Human Subject study. The study’s findings will be published in peer-reviewed journals and disseminated at national and international conferences and through social media.

Introduction: Large proportions of people living with HIV (PLHIV) in sub-Saharan Africa are not linked to or retained in HIV care. There is a critical need for cost-effective interventions to improve engagement and retention in care and inform optimal allocation of resources. Methods: We estimated costs associated with: a short message service (SMS) plus peer navigation (SMS+PN) intervention; an SMS-only intervention; and standard of care (SOC), within the I-Care cluster-randomized trial to improve HIV care engagement for recently diagnosed PLHIV. We employed a uniform cost data-collection protocol to quantify resources used and associated costs for each intervention. Results: Compared to SOC, the SMS+PN intervention cost $1284 ($828-$2859) more per additional patient linked to care within 30 days and $1904 ($1158-$5343) more per additional patient retained in care at 12 months, while improving linkage by 24% (95% CI=11%,36%) and retention by 16% (95% CI=6%,26%). In contrast, the SMS-only intervention cost $198 ($93-dominated) more per additional patient linked to care and $697 ($171-dominated) more per additional patient retained in care, but was not significantly associated with improvements in linkage (12%; 95% CI=-1,25) or retention (3%; 95% CI=-7,14) compared to SOC. The efficiency of the SMS+PN intervention could be improved by 46%, to $690 more per additional patient linked and $1023 more per additional patient retained in care, if implemented within the Department of Health (DoH) using more efficient distribution of staff resources. Discussion: Findings suggest scale-up of the SMS+PN intervention could benefit patients, improving care and health outcomes while being cost-effective. Copyright © 2024 Wolters Kluwer Health, Inc.

Background: With few psychometrically evaluated HIV related stigma measures for adolescents and young adults (AYA) living with HIV, we examined the developmental applicability (i.e., validity) of two subscales of the commonly used stigma measure, the Social Impact Scale (SIS), among a cohort of adolescents and young adults with perinatally-acquired HIV. Setting: Data came from a New York City longitudinal study (N=340). This study primarily comprises Black and Latinx AYA with either perinatally-acquired HIV (PHIV) or those with perinatal exposure but who are uninfected. Data for this analysis came from the PHIV population and spanned approximately a 15-year survey period (2003-2018). Methods: A confirmatory factor analysis was used at seven time points to assess if the Social Rejection and Internalized Shame subscales were consistent in this cohort over time. Overall and individual Cronbach’s alphas were reported to show the strength of the internal consistency. Results: Mean age from Baseline to Follow-Up 6 ranged from 12-23 years over the study period. The Social Rejection subscale was acceptably valid across follow-up periods with strong factor loadings and Cronbach’s alphas higher than 0.70. However, the Internalized Shame subscale was less valid among younger adolescents. Starting at Follow-Up 2, we observed better validity with the Internalized Shame subscale performance. Conclusion: Future research must consider mechanisms for developing and adapting measures from a developmental perspective to best measure the experiences of HIV-related stigma among younger populations.

Objective. We developed a robust characterization of immune recovery trajectories in people living with HIV (PWH) on antiretroviral treatment (ART) and relate our findings to epidemiological risk factors and bacterial pneumonia. Methods. Using data from the Swiss HIV Cohort Study and the Zurich Primary HIV Infection Cohort Study (n = 5907), we analyzed the long-term trajectories of CD4 cell and CD8 cell counts and their ratio in PWH on ART for at least eight years by fitting nonlinear mixed effects models. The determinants of long-term immune recovery were investigated using generalized additive models. In addition, prediction accuracy of the modeled trajectories and their impact on the fit of a model for bacterial pneumonia was assessed. Results. Overall, our population showed good immune recovery (median plateau [IQR]-CD4: 718 [555, 900] cells/µl, CD8: 709 [547, 893] cells/µl, CD4/CD8: 1.01 [0.76, 1.37]). The following factors were predictive of recovery: Age, sex, nadir/zenith value, pre-ART HIV-1 viral load, Hepatitis C, ethnicity, acquisition risk and timing of ART-initiation. The fitted models proved to be an accurate and efficient way of predicting future CD4+ and CD8+ cell recovery dynamics: Compared to carrying forward the last observation, mean squared errors of the fitted values were lower by 1.3% to 18.3% across outcomes. When modeling future episodes of bacterial pneumonia, using model-derived predictors improved most model fits. Conclusion. We described and validated a method to characterize individual immune recovery trajectories of PWH on suppressive ART. These trajectories accurately predict long-term immune recovery and the occurrence of bacterial pneumonia. Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.

Background: People with HIV (PWH) may be at risk for more severe COVID-19 outcomes. We compared risk for severe COVID-19 in PWH to matched individuals without HIV. Methods: We identified adults in Massachusetts with a positive SARS-CoV-2 test, March 2020-July 2022, using electronic medical record data from three large clinical practice groups. We then used regression models to compare outcomes among PWH versus propensity score-matched people without HIV (matched 20:1) for severe COVID-19 (pneumonia or acute respiratory distress syndrome), hospitalization, and hospital length-of-stay (LOS). Results: We identified 171,058 individuals with COVID-19; among them, 768 PWH were matched to 15,360 individuals without HIV. Overall, severe COVID-19 and hospitalization was similar in PWH and those without HIV (severe COVID-19: 3.8% vs 3.0%, adjusted OR 1.27, 95% CI 0.86-1.87; hospitalization:12.1% vs 11.3%, adjusted OR 1.08, 95% CI 0.87-1.35).

Receiving doxycycline after sex did not lead to fewer chlamydia or gonorrhea infections among cisgender women compared with standard care, according to results from a randomized clinical trial involving 449 participants aged 18 to 30 years in Kenya who were also receiving preexposure prophylaxis against HIV. These findings contrast previous research that showed taking doxycycline within 72 hours after a sexual encounter protects cisgender men who have sex with men and transgender women from sexually transmitted infections (STIs).

Abstract Background Diagnosis of tuberculous meningitis (TBM) is hampered by the lack of a gold standard. Current microbiological tests lack sensitivity and clinical diagnostic approaches are subjective. We therefore built a diagnostic model that can be used before microbiological test results are known. Methods We included 659 individuals aged (ge 16) years with suspected brain infections from a prospective observational study conducted in Vietnam. We fitted a logistic regression diagnostic model for TBM status, with unknown values estimated via a latent class model on three mycobacterial tests: Ziehl–Neelsen smear, Mycobacterial culture, and GeneXpert. We additionally re-evaluated mycobacterial test performance, estimated individual mycobacillary burden, and quantified the reduction in TBM risk after confirmatory tests were negative. We also fitted a simplified model and developed a scoring table for early screening. All models were compared and validated internally. Results Participants with HIV, miliary TB, long symptom duration, and high cerebrospinal fluid (CSF) lymphocyte count were more likely to have TBM. HIV and higher CSF protein were associated with higher mycobacillary burden. In the simplified model, HIV infection, clinical symptoms with long duration, and clinical or radiological evidence of extra-neural TB were associated with TBM At the cutpoints based on Youden’s Index, the sensitivity and specificity in diagnosing TBM for our full and simplified models were 86.0% and 79.0%, and 88.0% and 75.0% respectively. Conclusion Our diagnostic model shows reliable performance and can be developed as a decision assistant for clinicians to detect patients at high risk of TBM. Summary Diagnosis of tuberculous meningitis is hampered by the lack of gold standard. We developed a diagnostic model using latent class analysis, combining confirmatory test results and risk factors. Models were accurate, well-calibrated, and can support both clinical practice and research.

Abstract Background Little is known about the etiology, clinical presentation, management, and outcome of central nervous system (CNS) infections in Indonesia, a country with a high burden of infectious diseases and a rising prevalence of HIV. Methods We included adult patients with suspected CNS infections at two referral hospitals in a prospective cohort between April 2019 and December 2021. Clinical, laboratory, and radiological assessments were standardized. We recorded initial and final diagnoses, treatments, and outcomes during 6 months of follow-up. Results Of 1051 patients screened, 793 were diagnosed with a CNS infection. Patients (median age 33 years, 62% male, 38% HIV-infected) presented a median of 14 days (IQR 7–30) after symptom onset, often with altered consciousness (63%), motor deficits (73%), and seizures (21%). Among HIV-uninfected patients, CNS tuberculosis (TB) was most common (60%), while viral (8%) and bacterial (4%) disease were uncommon. Among HIV-infected patients, cerebral toxoplasmosis (41%) was most common, followed by CNS TB (19%), neurosyphilis (15%), and cryptococcal meningitis (10%). A microbiologically confirmed diagnosis was achieved in 25% of cases, and initial diagnoses were revised in 46% of cases. In-hospital mortality was 30%, and at six months, 45% of patients had died, and 12% suffered from severe disability. Six-month mortality was associated with older age, HIV, and severe clinical, radiological and CSF markers at presentation. Conclusion CNS infections in Indonesia are characterized by late presentation, severe disease, frequent HIV coinfection, low microbiological confirmation and high mortality. These findings highlight the need for earlier disease recognition, faster and more accurate diagnosis, and optimized treatment, coupled with wider efforts to improve the uptake of HIV services.
