OBJECTIVE: Approximately 40% of adults living with HIV experience cognitive deficits. Little is known about the risk factors for cognitive impairment and its association with myelin content in young adults living with perinatally acquired HIV (YApHIV), which is assessed in our cross-sectional study. DESIGN: A prospective, observational cohort study. METHODS: All participants underwent an 11-test cognitive battery and completed medical and social history surveys...

OBJECTIVE: Investigate the outcomes of women with HIV (WWH) with low-level viremia (LLV). DESIGN: The prevalence of LLV and potential clinical sequelae, such as virologic failure and non-AIDS comorbidity (NACM) development, are poorly characterized among WWH. METHODS: We analyzed data from the Women's Interagency HIV Study among WWH enrolled from 2003 to 2020 who reported antiretroviral therapy use at least 1 year followed by an HIV-1 viral load less than 200 copies/ml...

OBJECTIVES: We evaluated a recently developed and validated point-of-care urine tenofovir (POC TFV) test to determine whether its use improves the accuracy of self-reported adherence to pre-exposure prophylaxis (PrEP) and sexual behavior. DESIGN: We enrolled sexually active HIV-negative women ages 16-25 years in Kampala, Uganda. METHODS: Women were followed quarterly for 24 months with HIV prevention counseling, PrEP dispensation, and adherence counseling...

OBJECTIVES: To determine the metabolic effects of tenofovir alafenamide (TAF) compared to tenofovir disoproxil fumarate (TDF) in vivo. DESIGN AND METHODS: Male Wistar rats (Rattus novergicus, 250-300 g body weight) were divided into 3 groups (n = 8) and orally treated daily with 1.0 ml distilled water (group 1), TAF (0.42 mg/kg) (group 2), or TDF (5.0 mg/kg) (group 3), respectively, for 56 days. Glucose tolerance tests were done before the animals were sacrificed by halothane overdose, and blood was collected by cardiac puncture for the analysis of plasma lipids, electrolytes, and insulin...

OBJECTIVE: It is unclear how often anxiety is diagnosed and treated and whether anxiety treatment is associated with improved viral suppression in persons with HIV. In this study, we characterized the anxiety care continuum and its association with viral suppression in a large urban HIV clinic in the United States. DESIGN: Observational cohort study. METHODS: We described the anxiety care continuum by combining data on self-reported anxiety symptoms, engagement in mental health care, clinical diagnoses and prescriptions from 1,967 persons receiving HIV care and treatment in Baltimore, Maryland, from 2014-23...

OBJECTIVE: Assess the risk of death for offspring of pregnant women living with HIV (PWLHIV) and the association with sociodemographic, pregnancy, HIV-related, and birth factors. DESIGN: We conducted a prospective cohort study of PWLHIV on antiretroviral therapy (ART) and their offspring in urban Tanzania who were enrolled in a vitamin D trial conducted from June 2015 to October 2019. METHODS: We described rates of fetal, neonatal, and infant death and assessed risk factors for these outcomes with generalized estimating equations...

OBJECTIVES: We aimed to determine the prevalence of HIV-related stigma among people with HIV (PWH) in Switzerland. DESIGN: A cross-sectional multicentre study nested within the Swiss HIV Cohort Study (SHCS). METHODS: We included adult PWH enrolled in the SHCS, attending follow-up between March 1st, 2020, and January 31st, 2021. Inability to speak English, French, German, or Italian was the only exclusion criterion. Participants were invited to complete a validated 12-item HIV-stigma questionnaire comprising four stigma subscales (negative self-image, personalised stigma, disclosure concerns, and concerns regarding public attitudes), plus two healthcare-related stigma items...

OBJECTIVE: Diabetes mellitus (DM) is associated with lower antiretroviral (ART) drug exposure among persons with HIV (PWH) compared to PWH without DM. The association between DM and virologic control in PWH, however, remains unknown. METHODS: We included participants in the Multicenter AIDS Cohort Study/Women's Interagency HIV Study Combined Cohort Study (MWCCS) who had initiated ART between 1999 and 2020 and had a suppressed HIV viral load (≤200 copies/mL) within 1 year of ART initiation...

OBJECTIVE: Biological markers of stress have been associated with HIV progression and pathogenesis but not with HIV incidence. We sought to determine if elevated stress-responsive biomarkers would be associated with incident HIV among adolescent girls and young women (AGYW). DESIGN: We conducted a case-cohort study within the HIV Prevention Trials Network (HPTN) 068 study among 949 AGYW in South Africa. Cases were AGYW who tested HIV-positive during the eight-year follow-up...

OBJECTIVE: To examine the risk of preterm birth (PTB) and small for gestational age (SGA) among women living with HIV compared to women without HIV. Secondary objectives were to explore the role of maternal immune activation (IA) and effect of cART timing on these outcomes. DESIGN: Prospective observational cohort. SETTING: Urban government-run clinic at Chawama Hospital in Lusaka, Zambia. PARTICIPANTS: 1481 women with and without HIV with singleton pregnancies enrolled before 26 weeks' gestation by ultrasound dating...

INTRODUCTION: The window period, defined as HIV nucleic acid test (NAT) reactivity but Western blot (WB) test inconclusive, is garnering more attention. Improving the detection efficiency of HIV high-risk populations in the window period is critical to reducing the risk of unanticipated transmission. The purpose of this study was to create an additional strategy for distinguishing indeterminate HIV infection cases. METHODS: Based on WB follow-up results, the individuals in this study were divided into persons in the HIV window period and persons without HIV...

BACKGROUND: The methamphetamine epidemic threatens progress towards ending the HIV epidemic in the United States. Further characterizing the prevalence and impact of methamphetamine use among people with HIV (PWH) is necessary to inform integrated HIV and methamphetamine treatment strategies. METHODS: We conducted a retrospective chart review to characterize methamphetamine use among 3,092 PWH at an urban HIV Medicine clinic between July 1, 2022 and June 30, 2023...

OBJECTIVE: To ascertain whether a novel expanded social network recruitment to HIV testing (E-SNRHT) intervention recruits men and individuals with previously-undiagnosed HIV at higher rates than risk network recruitment. DESIGN: Initial "seed" participants were prospectively randomly assigned to the E-SNRHT intervention or to risk network recruitment. Their network members were included in the study arm of their recruiter. SETTING: Three Department of Health clinics and two drug treatment centers (DTCs) in the Msunduzi municipality of KwaZulu-Natal, South Africa...

OBJECTIVES: To estimate the epidemiological impact of past HIV interventions and the magnitude and contribution of undiagnosed HIV among different risk groups on new HIV acquisitions in Côte d'Ivoire, Mali and Senegal. DESIGN: HIV transmission dynamic models among the overall population and key populations [female sex workers (FSW), their clients, and MSM]. METHODS: Models were independently parameterized and calibrated for each set of country-specific demographic, behavioural, and epidemiological data...

OBJECTIVE: To evaluate if integrated cervical cancer screening (CCS) for women living with HIV (WLWH) in routine HIV care resulted in increased adherence to screening, and to describe the prevalence of Human Papillomavirus (HPV)-specific genotypes and the incidence of cellular abnormalities. DESIGN: Cohort study. METHODS: WLWH who accepted the offer of combined CCS and HIV care (Group 1), WLWH who declined the offer (Group 2), and WLWH not offered CCS within HIV care (Group 3) between 2013-2019 were included...

OBJECTIVE: :Mass screening for human immunodeficiency virus (HIV) and preexposure prophylaxis (PrEP) may be effective measures for reducing the probability of HIV transmission. Our study aimed to determine the cost-effectiveness of preliminary screening in the general population, PrEP for HIV-negative spouses in serodiscordant couples, or both approaches in Zhejiang Province. DESIGN: :From a policy-maker's perspective, a Markov model was constructed to compare 4 strategies over a 30-year horizon...

OBJECTIVE: Risk factors for progression from prediabetes (pre-DM) to diabetes (DM) among people with HIV (PWH) receiving modern antiretroviral therapy (ART) require better characterization. DESIGN: AIDS Clinical Trials Group (ACTG) A5322 (HAILO) was an observational cohort study of PWH ≥40 years old. Participants initiated ART through ACTG randomized clinical trials. METHODS: We used Cox proportional hazards regression models to identify risk factors for development of DM among HAILO participants with pre-DM...

BACKGROUND: Young men who have sex with men and transgender women (YMSM/TGW) have disproportionately high HIV incidence and lower PrEP adherence. Point-of-care (POC) urine tenofovir (TFV) rapid assay (UTRA) testing permits real-time monitoring for nonadherence within clinical settings. We performed UTRA testing among PrEP users to examine the relationship between low PrEP adherence and future PrEP discontinuation, and the accuracy of POC testing compared to gold-standard liquid chromatography tandem mass spectrometry (LC/MS/MS)...

OBJECTIVE: To identify groups more likely to be referred for HIV testing because of symptomatic presentation rather than as part of asymptomatic screening. DESIGN: A retrospective analysis of Australian National HIV Registry (NHR) surveillance data including sociodemographic and clinical data, as well as reasons for HIV test. METHODS: Using notification records from 2017 to 2022, we summarised reasons for testing leading to an HIV diagnosis...
