HIV Immunocapture Reveals Particles Expressed in Semen Under Integrase Strand Transfer Inhibitor-Based Therapy Are Largely Myeloid Cell-Derived and Disparate.

As use of human immunodeficiency virus (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 of 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.

Viral Suppression Trajectories Destabilized After Coronavirus Disease 2019 Among US People With Human Immunodeficiency Virus: An Interrupted Time Series Analysis.

We examined changes in the proportion of people with human immunodeficiency virus (PWH) with virologic suppression (VS) in a multisite US cohort before and since the coronavirus disease 2019 (COVID-19) pandemic. Overall, prior gains in VS slowed during COVID-19, with disproportionate impacts on Black PWH and PWH who inject drugs.

HIV-1 Incidence, Adherence, and Drug Resistance in Individuals Taking Daily Emtricitabine/Tenofovir Disoproxil Fumarate for HIV-1 Pre-Exposure Prophylaxis: Pooled Analysis From 72 Global Studies.

BACKGROUND: Oral pre-exposure prophylaxis (PrEP) with emtricitabine/tenofovir disoproxil fumarate (F/TDF) has high efficacy against HIV-1 acquisition. Seventy-two prospective studies of daily oral F/TDF PrEP were conducted to evaluate HIV-1 incidence, drug resistance, adherence, and bone and renal safety in diverse settings. METHODS: HIV-1 incidence was calculated from incident HIV-1 diagnoses after PrEP initiation and within 60 days of discontinuation. Tenofovir concentration in dried blood spots (DBS), drug resistance, and bone/renal safety indicators were evaluated in a subset of studies. RESULTS: Among 17,274 participants, there were 101 cases with new HIV-1 diagnosis (0.77 per 100 person-years; 95% CI 0.63-0.94). In 78 cases with resistance data, 18 (23%) had M184I or V, one (1.3%) had K65R, and three (3.8%) had both mutations. In 54 cases with tenofovir concentration data from DBS, 45 (83.3%), 2 (3.7%), 6 (11.1%), and 1 (1.9%) had average adherence of <2, 2-3, 4-6, and ≥7 doses/week, respectively, and the corresponding incidence was 3.9 (95% CI 2.9-5.3), 0.24 (0.060-0.95), 0.27 (0.12-0.60), and 0.054 (0.008-0.38) per 100 person-years. Adherence was low in younger participants, Hispanic/Latinx and Black participants, cisgender women, and transgender women. Bone and renal adverse event incidence rates were 0.69 and 11.8 per 100 person-years, respectively, consistent with previous reports. CONCLUSIONS: Leveraging the largest pooled analysis of global PrEP studies to date, we demonstrate that F/TDF is safe and highly effective, even with less than daily dosing, in diverse clinical settings, geographies, populations, and routes of HIV-1 exposure.

Barriers to engagement in the care cascade for tuberculosis disease in India: A systematic review of quantitative studies.

BACKGROUND: India accounts for about one-quarter of people contracting tuberculosis (TB) disease annually and nearly one-third of TB deaths globally. Many Indians do not navigate all care cascade stages to receive TB treatment and achieve recurrence-free survival. Guided by a population/exposure/comparison/outcomes (PECO) framework, we report findings of a systematic review to identify factors contributing to unfavorable outcomes across each care cascade gap for TB disease in India. METHODS AND FINDINGS: We defined care cascade gaps as comprising people with confirmed or presumptive TB who did not: start the TB diagnostic workup (Gap 1), complete the workup (Gap 2), start treatment (Gap 3), achieve treatment success (Gap 4), or achieve TB recurrence-free survival (Gap 5). Three systematic searches of PubMed, Embase, and Web of Science from January 1, 2000 to August 14, 2023 were conducted. We identified articles evaluating factors associated with unfavorable outcomes for each gap (reported as adjusted odds, relative risk, or hazard ratios) and, among people experiencing unfavorable outcomes, reasons for these outcomes (reported as proportions), with specific quality or risk of bias criteria for each gap. Findings were organized into person-, family-, and society-, or health system-related factors, using a social-ecological framework. Factors associated with unfavorable outcomes across multiple cascade stages included: male sex, older age, poverty-related factors, lower symptom severity or duration, undernutrition, alcohol use, smoking, and distrust of (or dissatisfaction with) health services. People previously treated for TB were more likely to seek care and engage in the diagnostic workup (Gaps 1 and 2) but more likely to suffer pretreatment loss to follow-up (Gap 3) and unfavorable treatment outcomes (Gap 4), especially those who were lost to follow-up during their prior treatment. For individual care cascade gaps, multiple studies highlighted lack of TB knowledge and structural barriers (e.g., transportation challenges) as contributing to lack of care-seeking for TB symptoms (Gap 1, 14 studies); lack of access to diagnostics (e.g., X-ray), non-identification of eligible people for testing, and failure of providers to communicate concern for TB as contributing to non-completion of the diagnostic workup (Gap 2, 17 studies); stigma, poor recording of patient contact information by providers, and early death from diagnostic delays as contributing to pretreatment loss to follow-up (Gap 3, 15 studies); and lack of TB knowledge, stigma, depression, and medication adverse effects as contributing to unfavorable treatment outcomes (Gap 4, 86 studies). Medication nonadherence contributed to unfavorable treatment outcomes (Gap 4) and TB recurrence (Gap 5, 14 studies). Limitations include lack of meta-analyses due to the heterogeneity of findings and limited generalizability to some Indian regions, given the country's diverse population. CONCLUSIONS: This systematic review illuminates common patterns of risk that shape outcomes for Indians with TB, while highlighting knowledge gaps-particularly regarding TB care for children or in the private sector-to guide future research. Findings may inform targeting of support services to people with TB who have higher risk of poor outcomes and inform multicomponent interventions to close gaps in the care cascade.

Safety and pharmacokinetics of VRC07-523LS administered via different routes and doses (HVTN 127/HPTN 087): A Phase I randomized clinical trial.

BACKGROUND: Broadly neutralizing antibodies (bnAbs) are a promising approach for HIV-1 prevention. In the Antibody Mediated Prevention (AMP) trials, a CD4-binding site targeting bnAb, VRC01, administered intravenously (IV), demonstrated 75% prevention efficacy against highly neutralization-sensitive viruses but was ineffective against less sensitive viruses. VRC07-523LS is a next-generation bnAb targeting the CD4-binding site and was engineered for increased neutralization breadth and half-life. We conducted a multicenter, randomized, partially blinded Phase I clinical trial to evaluate the safety and serum concentrations of VRC07-523LS, administered in multiple doses and routes to healthy adults without HIV. METHODS AND FINDINGS: Participants were recruited between 2 February 2018 and 9 October 2018. A total of 124 participants were randomized to receive 5 VRC07-523LS administrations via IV (T1: 2.5 mg/kg, T2: 5 mg/kg, T3: 20 mg/kg), subcutaneous (SC) (T4: 2.5 mg/kg, T5: 5 mg/kg), or intramuscular (IM) (T6: 2.5 mg/kg or P6: placebo) routes at 4-month intervals. Participants and site staff were blinded to VRC07-523LS versus placebo for the IM group, while all other doses and routes were open-label. Safety data were collected for 144 weeks following the first administration. VRC07-523LS serum concentrations were measured by ELISA through Day 112 in all participants and by binding antibody multiplex assay (BAMA) thereafter in 60 participants (10 per treatment group) through Day 784. Compartmental population pharmacokinetic (PK) analyses were conducted to evaluate the VRC07-523LS serum PK. Neutralization activity was measured in a TZM-bl assay and antidrug antibodies (ADAs) were assayed using a tiered bridging assay testing strategy. Injections and infusions were well tolerated, with mild pain or tenderness reported commonly in the SC and IM groups, and mild to moderate erythema or induration reported commonly in the SC groups. Infusion reactions were reported in 3 of 20 participants in the 20 mg/kg IV group. Peak geometric mean (GM) concentrations (95% confidence intervals [95% CIs]) following the first administration were 29.0 µg/mL (25.2, 33.4), 58.5 µg/mL (49.4, 69.3), and 257.2 µg/mL (127.5, 518.9) in T1-T3 with IV dosing; 10.8 µg/mL (8.8, 13.3) and 22.8 µg/mL (20.1, 25.9) in T4-T5 with SC dosing; and 16.4 µg/mL (14.7, 18.2) in T6 with IM dosing. Trough GM (95% CIs) concentrations immediately prior to the second administration were 3.4 µg/mL (2.5, 4.6), 6.5 µg/mL (5.6, 7.5), and 27.2 µg/mL (23.9, 31.0) with IV dosing; 0.97 µg/mL (0.65, 1.4) and 3.1 µg/mL (2.2, 4.3) with SC dosing, and 2.6 µg/mL (2.05, 3.31) with IM dosing. Peak VRC07-523LS serum concentrations increased linearly with the administered dose. At a given dose, peak and trough concentrations, as well as serum neutralization titers, were highest in the IV groups, reflecting the lower bioavailability following SC and IM administration. A single participant was found to have low titer ADA at a lone time point. VRC07-523LS has an estimated mean half-life of 42 days across all doses and routes (95% CI: 40.5, 43.5), over twice as long as VRC01 (15 days). CONCLUSIONS: VRC07-523LS was safe and well tolerated across a range of doses and routes and is a promising long-acting bnAb for inclusion in HIV-1 prevention regimens.

Causal Effects of Stochastic PrEP Interventions on HIV Incidence Among Men Who Have Sex With Men.

Antiretroviral preexposure prophylaxis (PrEP) is highly effective in preventing human immunodeficiency virus (HIV) infection, but uptake has been limited and inequitable. Although interventions to increase PrEP uptake are being evaluated in clinical trials among men who have sex with men (MSM), those trials cannot evaluate effects on HIV incidence. Estimates from observational studies of the causal effects of PrEP-uptake interventions on HIV incidence can inform decisions about intervention scale-up. We used longitudinal electronic health record data from HIV-negative MSM accessing care at Fenway Health, a community health center in Boston, Massachusetts, from January 2012 through February 2018, with 2 years of follow-up. We considered stochastic interventions that increased the chance of initiating PrEP in several high-priority subgroups. We estimated the effects of these interventions on population-level HIV incidence using a novel inverse-probability weighted estimator of the generalized g-formula, adjusting for baseline and time-varying confounders. Our results suggest that even modest increases in PrEP initiation in high-priority subgroups of MSM could meaningfully reduce HIV incidence in the overall population of MSM. Interventions tailored to Black and Latino MSM should be prioritized to maximize equity and impact.

Performance of the Applied Biosystems HIV-1 Genotyping Kit with Integrase.

HIV genotyping is used to assess HIV susceptibility to antiretroviral drugs. The Applied Biosystems HIV-1 Genotyping Kit with Integrase (AB kit, Thermo Fisher Scientific) detects resistance-associated mutations (RAMs) in HIV protease (PR), reverse transcriptase (RT), and integrase (IN). We compared results from the AB kit with results obtained previously with the ViroSeq HIV-1 Genotyping System. DNA amplicons from the AB kit were also analyzed using next-generation sequencing (NGS). HIV RNA was extracted using the MagNA Pure 24 instrument (Roche Diagnostics; 96 plasma samples, HIV subtype B, viral load range: 530-737,741 copies/mL). FASTA files were generated from AB kit data using Exatype (Hyrax Biosciences). DNA amplicons from the AB kit were also analyzed by NGS using the Nextera XT kit (Illumina). Drug resistance was predicted using the Stanford HIV Drug Resistance Database. The mean genetic distance for sequences from ViroSeq and the AB kit was 0.02% for PR/RT and 0.04% for IN; 103 major RAMs were detected by both methods. Four additional major RAMs were detected by the AB kit only. These four major RAMs were also detected by NGS (detected in 18.1%-38.2% of NGS reads). NGS detected 27 major RAMs that were not detected with either of the Sanger sequencing-based kits. All major RAMs detected with ViroSeq were detected with the AB kit; additional RAMs were detected with the AB kit only. DNA amplicons from the AB kit can be used for NGS for more sensitive detection of RAMs.

Use of doxycycline and other antibiotics as bacterial sexually transmitted infection prophylaxis in a U.S. sample of primarily gay and bisexual men.

BACKGROUND: Doxycycline used as post-exposure prophylaxis (doxyPEP) within 72 hours of sex reduces the risk of bacterial sexually transmitted infections (STIs) in people assigned male sex at birth. Little is known about current use of antibiotics as STI prophylaxis in U.S. populations likely to benefit from doxyPEP. METHODS: We conducted an online survey in September 2023 of U.S. adults recruited via sexual networking apps used mainly by gay and bisexual men (GBM). Respondents were asked about the use of antibiotics around the time of sex to prevent bacterial STIs. RESULTS: Of 903 respondents, most (96.2%) identified as GBM; 19.0% were living with HIV and 42.5% using HIV pre-exposure prophylaxis. Half (49.1%) had heard of using antibiotics to prevent STIs and 95.6% were interested in use. Overall, 21.0% had used antibiotic STI prophylaxis and 15.9% had done so in the past year. Among those reporting any use, most (78.1%) had used doxycycline; some used amoxicillin (16.7%), azithromycin (14.5%), or other antibiotics (14.1%). Among those reporting use in the past year, 46.9% used it for some, 28.1% for most, and 25.0% for all sex acts with casual partners during that period. Most (78.3%) of STI prophylaxis users reported their condom use did not change during periods of STI prophylaxis use, 17.2% indicated their condom use declined, and 4.5% indicated their condom use increased. For doxyPEP specifically, 35.7% had heard of it and 13.0% had used it in the past year, of whom 21.0% had used a dosage other than the 200 mg dose shown to be effective. CONCLUSIONS: In this sample of primarily GBM, interest in bacterial STI prophylaxis was nearly universal. However, some of the use was not informed by current clinical guidance or evidence from research studies. Efforts are needed to increase awareness of effective dosing and monitor real-world use.

Estimating the Proportion of People Living With HIV Who May Benefit From the Reverse Algorithm for the Diagnosis of Incident Syphilis.

ABSTRACT: Among 8455 people engaged in HIV care in 4 US cities, 4925 (58%) had treponemal testing at care entry. Of the 4925 tested, 3795 (77%) had a nonreactive result and might benefit from the reverse algorithm for a future incident syphilis diagnosis. Furthermore, low-barrier treponemal testing as a first step in the reverse algorithm may increase syphilis screening and decrease time to treatment.

Weighing the Options: Which PrEP (Pre-exposure Prophylaxis) Modality Attributes Influence Choice for Young Gay and Bisexual Men in the United States?

Pre-exposure prophylaxis (PrEP) is effective in preventing HIV transmission, but uptake and adherence among young men who have sex with men (YMSM) remains suboptimal. New PrEP formulations may enhance PrEP use, but little is known about their acceptability. We enrolled 39 cis- and transgender YMSM (age 18-34) from Boston, MA; Jackson, MS; Birmingham, AL; and New Orleans, LA, who participated in video-based focus groups (n = 30) or in-depth interviews (n = 9) to examine how new PrEP products (e.g., injections, monthly pills, implants) are perceived and might be improved for YMSM. Focus groups were transcribed, coded, and analyzed using grounded theory and content analysis. Nearly half (46%) of participants were Black; 11% identified as Hispanic. Seventy-nine percent were PrEP experienced. Product preference was driven by the desire for flexible, safe, effective, and affordable PrEP options. A majority of participants preferred subcutaneous injections every 6 months or monthly pills dispersed in 3 or 4 doses. Subcutaneous injections and batched monthly pills were favored by those with demanding schedules and those who desired fewer provider visits; monthly pills were more appealing for those who feared needles. Despite broad preferences for longer-acting products for convenience, participants raised concerns regarding side effects and waning protection after missed doses. Participants felt that more education about safety and efficacy profiles of new products could influence their attitudes. These findings suggest that it is important to prioritize YMSM's dynamic lifestyles during product development, and that product safety and efficacy information should be accessible in youth-friendly language.

Efficacy of Behavioral Intervention, Text Messaging, and Extended Intervention to Address Alcohol Misuse in Sexual Minority Men with HIV: A Factorial Randomized Clinical Trial.

This clinical trial examined the individual and combined effects of three different approaches to reducing alcohol misuse among a sample of sexual minority men (SMM) with HIV. Specifically, we used a 2 × 2 × 2 randomized factorial design to compare: (a) behavioral intervention based in motivational interviewing (MI) vs. brief intervention (BI), (b) interactive text messaging (ITM) for alcohol use vs. no ITM, and (c) extended intervention (EI) length of nine months vs. a one-month intervention duration. Participants (N = 188) were SMM with HIV and alcohol misuse recruited in Miami, FL, and Boston, MA. Participants were randomized to one of eight intervention combinations and assessed at 6- and 12-month follow-ups. Large reductions of over 50% in drinks per week and heavy drinking days were observed in all conditions at follow-up. Those who received ITM, compared to those who did not, reported significantly lower drinks consumed per week at 6 and 12 months (incidence rate ratios = 0.73 [95% CI = 0.57, 0.90] and 0.72 [95% CI = 0.56, 0.87], respectively), and increased odds of cessation of alcohol misuse at 12 months, odds ratio = 1.46, 95% CI = 1.03, 2.08. Results provided no evidence of better alcohol use outcomes for either MI or EI relative to their comparison conditions, and no specific combination of intervention components demonstrated a notable benefit. This study suggests a two-session BI can effectuate substantial reductions in alcohol use in SMM with HIV and that adding one month of ITM can yield further improvements. Clinical Trials Number: NCT02709759.

PrEP Stigma as a Minority Stressor among Black Sexual Minority Men: A Mixed-Methods Study.

Black sexual minority men (BSMM) remain disproportionately affected by HIV, yet Pre-exposure prophylaxis (PrEP) uptake in this population remains relatively low. Informed by minority stress theory, PrEP stigma may manifest in and exacerbate societal marginalization based on sexuality and race. We used an exploratory sequential mixed-methods approach to determine if PrEP-specific stigma was associated with reduced PrEP uptake among BSMM, and qualitatively explored how PrEP use is stigmatized among BSMM. We analyzed cross-sectional data from a pilot sample of BSMM (n = 151) collected in late 2020 in the United States, testing for associations between PrEP stigma and PrEP use using modified Poisson regression. Subsequently, we selected participants (n = 23) from this sample for qualitative interviews starting in 2022. Responses to questions related to PrEP stigma were analyzed using thematic analysis. PrEP stigma was associated less than half the PrEP use (aPR = 0.43, 95% CI = 0.24, 0.75) among BSMM after adjustment. Qualitatively, we identified three major themes in how PrEP use is stigmatized among BSMM: PrEP-specific sexual stigma, intersections between PrEP and HIV stigma, and PrEP misinformation and disinformation. Aligned with minority stress theory, each theme was based in part in stigma related to sexuality or race. We found strong relationships between PrEP stigma and PrEP use independent of several sociobehavioral factors. Each of our themes were based in part in minority stressors, and underscore the importance of culturally competent PrEP promotion efforts towards BSMM. Addressing stigma is a core component of health equity efforts towards ending the HIV epidemic.

Pharmacologic Drug Detection and Self-Reported Adherence in the HPTN069/ACTG5305 Phase II PrEP Trial.

Adherence drives efficacy in PrEP clinical trials. We compared drug concentrations and self-reported adherence in HPTN069/ACTG5305, a double-blinded, randomized trial of the safety and tolerability of candidate PrEP regimens that included maraviroc (MVC), tenofovir (TDF), and emtricitabine (FTC). Plasma drug concentrations and self-reported adherence by computer-assisted self-interview (CASI) were assessed at study weeks 24 and 48. Descriptive statistics and a generalized linear model were used to assess the association between selected demographic factors, self-report of daily medication adherence and plasma drug concentrations consistent with daily adherence. Among 718 paired observations from 370 participants, 43% (306/718) reported daily adherence by CASI, 65% (467/718) had drug concentrations consistent with daily adherence and 11% (81/718) had CASI responses that reported daily adherence despite having drug concentrations consistent with less-than-daily adherence. In adjusted analyses, participants who were assigned male at birth (aOR 1.42 [95% CI 1.02, 1.97]), older (5-year increments aOR 1.10 [95% CI 1.09, 1.11]), White (aOR 2.2 [95% CI 1.88, 2.56]), had advanced education (aOR 3.89 [95% CI 2.97, 5.09]), were employed (aOR 1.89 [95% CI 1.50, 2.40]), or partnered/married (aOR 2 [95% CI 1.72, 2.32]) were more likely to have drug concentrations consistent with daily adherence. Participants who were not employed (aOR 2.7 [95% CI 1.31, 5.55]) or who were single/not partnered (aOR 2.33 [CI 95% 1.25, 4.34]) were more likely to have drug concentrations that did not reflect daily adherence despite self-reported PrEP adherence. These findings support the need for ongoing adherence counseling in clinical trials of new PrEP regimens.

Leveraging A Digital Pill System to Understand Prevention-Effective Adherence to Oral Hiv Pre-Exposure Prophylaxis Among Men Who Have Sex with Men with Substance Use.

Daily oral pre-exposure prophylaxis (PrEP) is highly effective for HIV prevention, though efficacy depends on adherence. Digital pill systems (DPS) can enable direct, real-time adherence measurement. HIV-negative men who have sex with men (MSM) with substance use (excluding alcohol) utilized a DPS over 90 days and completed weekly surveys reporting sexual activity, condom use, and substance use. Responses indicating (1) any sexual activity and substance use or (2) condomless anal intercourse (CAI) in the prior week were categorized as high risk for HIV acquisition. PrEP adherence data for the 7-day period preceding each response was dichotomized as ≤ 3 and ≥ 4 doses/week, indicating prevention-effective adherence, and compared by HIV risk level. Thirteen MSM were analyzed (median age: 32). Of 113 surveys, 48.7% indicated high HIV risk, with 12.4% reporting CAI alone, 16.8% any sexual activity and substance use, and 19.5% both CAI and substance use. Weekly mean PrEP adherence was 90.3% (6.3 of 7 doses/week), with ≥ 4 doses/week recorded during 92.0% of weeks. The proportion of participants with ≥ 4 recorded doses/week was 88.9% during weeks with CAI alone, 89.5% during weeks with any sexual activity and substance use, 92.0% during weeks with both CAI and substance use, and 92.8% during lower risk weeks. Participants ingested ≥ 4 doses/week during 89.1% of all high-risk weeks and 94.8% of low-risk weeks. Overall, participants maintained high levels of PrEP adherence while engaging in HIV risk behaviors. DPS can be deployed concurrently with data collection tools to assess ingestion patterns during periods of elevated risk.

A Peer-to-Peer Collaborative Learning Approach for the Implementation of Evidence-Informed Interventions to Improve HIV-Related Health Outcomes.

The nationwide scale-up of evidence-based and evidence-informed interventions has been widely recognized as a crucial step in ending the HIV epidemic. Although the successful delivery of interventions may involve intensive expert training, technical assistance (TA), and dedicated funding, most organizations attempt to replicate interventions without access to focused expert guidance. Thus, there is a grave need for initiatives that meaningfully address HIV health disparities while addressing these inherent limitations. Here, the Health Resources and Services Administration HIV/AIDS Bureau (HRSA HAB) initiative Using Evidence-Informed Interventions to Improve HIV Health Outcomes among People Living with HIV (E2i) piloted an alternative approach to implementation that de-emphasized expert training to naturalistically simulate the experience of future HIV service organizations with limited access to TA. The E2i approach combined the HAB-adapted Institute for Healthcare Improvement's Breakthrough Series Collaborative Learning Model with HRSA HAB's Implementation Science Framework, to create an innovative multi-tiered system of peer-to-peer learning that was piloted across 11 evidence-informed interventions at 25 Ryan White HIV/AIDS Program sites. Four key types of peer-to-peer learning exchanges (i.e., intervention, site, staff role, and organization specific) took place at biannual peer learning sessions, while quarterly intervention cohort calls and E2i monthly calls with site staff occurred during the action periods between learning sessions. Peer-to-peer learning fostered both experiential learning and community building and allowed site staff to formulate robust site-specific action plans for rapid cycle testing between learning sessions. Strategies that increase the effectiveness of interventions while decreasing TA could provide a blueprint for the rapid uptake and integration of HIV interventions nationwide.

Association of Alcohol Use with COVID-19 Infection and Hospitalization Among People Living with HIV in the United States, 2020.

Alcohol use was associated with elevated COVID-19 risk in the general population. People with HIV (PWH) have high prevalences of alcohol use. To evaluate the effect of alcohol use on COVID-19 risks among PWH, we estimated the risk of COVID-19 diagnosis and COVID-19-related hospitalization among PWH in routine care at 8 HIV primary care centers that contributed data to the Centers for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort according to their alcohol use just prior to the COVID-19 pandemic. The CNICS data repository includes demographic characteristics, clinical diagnoses, and laboratory test results from electronic medical records and other sources. Alcohol use, substance use, and mental health symptoms were self-reported on tablet-based standardized surveys. Alcohol use was categorized according to standard, sex-specific Alcohol Use Disorder Identification Test-Consumption instrument cut-offs. We followed 5,496 PWH (79% male, 48% Black race, median age = 53 years) from March 1, 2020 to December 31, 2020. Relative to PWH with no baseline alcohol use, the adjusted hazard ratio (aHR) of COVID-19 diagnosis was 1.09 (95% confidence interval [CI]: 0.78, 1.51) for lower-risk drinking and 1.19 (95%CI: 0.81, 1.73) for unhealthy drinking. The aHR of COVID-19-related hospitalization was 0.82 (95%CI: 0.33, 1.99) for lower-risk drinking and 1.25 (95%CI: 0.50, 3.09) for unhealthy drinking. Results were not modified by recent cocaine or non-prescribed opioid use, depressive symptoms, or diagnoses of alcohol use disorder. The study suggested a slightly increased, but not statistically significant risk of COVID-19 diagnosis and hospitalization associated with unhealthy alcohol use.

Social and structural factors associated with interest in HIV preexposure prophylaxis among Black women in the United States.

In a nationwide sample of cisgender Black women in the US, we assessed the associations between social and structural factors and interest in using HIV preexposure prophylaxis (PrEP). Among 315 respondents, 62.2% were interested in PrEP if it were provided for free. Positive social norms surrounding PrEP, including injunctive norms (perceived social acceptability of PrEP use) and descriptive norms (perceived commonality of PrEP use), were positively associated with interest in using PrEP. Concerns about HIV infection, recently visiting a health care provider, and comfort discussing PrEP with a provider were also positively associated with interest in using PrEP. Anticipating PrEP disapproval from others was negatively associated with interest in PrEP. Although PrEP can promote autonomy and personal discretion, Black women's PrEP-related decisions occur in a complex social environment. Black women may benefit from interventions to promote positive norms and attitudes surrounding PrEP at the community level and empower them in discussions with their providers about PrEP.

Development of a home-based pre-exposure prophylaxis care delivery system for long-acting injectable cabotegravir: a formative exploration of patient preferences.

Cabotegravir (CAB-LA), the only Food and Drug Administration-approved injectable pre-exposure prophylaxis (PrEP), is effective and may address PrEP uptake disparities among Black and Latino sexual and gender minority (SGM) men. Uptake of CAB-LA may require developing innovative non-clinic-based care delivery strategies in home-based settings. We explored SGM men's opinions on a future home-based CAB-LA PrEP care service to guide the adaptation of PrEP@Home, an existing home-based PrEP system for oral PrEP. Through 14 in-depth interviews with current or former SGM male participants in the PrEP@Home study, we explored the acceptability of a home-based injectable PrEP system and examined visit and communication-related preferences. All participants considered home-based CAB-LA care to be acceptable and 8/14 would utilize the system if available. Convenience and comfort with using a home-based system impacted the overall acceptance of the approach. Factors influencing acceptability included clinical teams' affiliation with healthcare systems, a credentialed two-person team, and staff identity verification methods. Logistical preferences included communicating pre-visit patient instructions, allowing flexible scheduling hours, and the use of text, phone calls, or mobile app communication methods based on urgency. Conclusively, a home-based CAB-LA PrEP delivery system was acceptable among the interviewed SGM men, guiding its development and future implementation.Trial registration: ClinicalTrials.gov identifier: NCT03569813.

Expectations of preventative benefits and risk behaviors in a randomized trial evaluating oral HIV preexposure prophylaxis candidates.

When participants enrolled in an HIV prevention trial hold a preventive misconception (PM) - expectations that experimental interventions will confer protection from HIV infection - they may engage in behaviors that increase their risk of acquiring HIV. This can raise ethical concerns about whether those enrolled in the trial understand the nature of participation and their safety. Consequently, we systematically evaluated the prevalence of PM and its association with risk behaviors in a trial examining three candidate regimens for oral HIV pre-exposure prophylaxis in which all participants received at least one antiretroviral agent. Overall, trial participants exhibited relatively high preventive expectations that may be associated with an increase in risk behaviors among men who have sex with men. In addition, we identified substantial site variability in PM that necessitates future research to uncover its source. This will allow appropriate measures to be taken to mitigate PM and help ensure that participants have an accurate understanding of the potential risks and benefits of trial participation throughout the course of a trial.

Association between SARS-CoV-2 infection and select symptoms and conditions 31 to 150 days after testing among children and adults.

BACKGROUND: An increasing number of studies have described new and persistent symptoms and conditions as potential post-acute sequelae of SARS-CoV-2 infection (PASC). However, it remains unclear whether certain symptoms or conditions occur more frequently among persons with SARS-CoV-2 infection compared with those never infected with SARS-CoV-2. We compared the occurrence of specific COVID-associated symptoms and conditions as potential PASC 31- to 150-day following a SARS-CoV-2 test among adults and children with positive and negative test results. METHODS: We conducted a retrospective cohort study using electronic health record (EHR) data from 43 PCORnet sites participating in a national COVID-19 surveillance program. This study included 3,091,580 adults (316,249 SARS-CoV-2 positive; 2,775,331 negative) and 675,643 children (62,131 positive; 613,512 negative) who had a SARS-CoV-2 laboratory test during March 1, 2020-May 31, 2021 documented in their EHR. We used logistic regression to calculate the odds of having a symptom and Cox models to calculate the risk of having a newly diagnosed condition associated with a SARS-CoV-2 positive test. RESULTS: After adjustment for baseline covariates, hospitalized adults and children with a positive test had increased odds of being diagnosed with ≥ 1 symptom (adults: adjusted odds ratio[aOR], 1.17[95% CI, 1.11-1.23]; children: aOR, 1.18[95% CI, 1.08-1.28]) or shortness of breath (adults: aOR, 1.50[95% CI, 1.38-1.63]; children: aOR, 1.40[95% CI, 1.15-1.70]) 31-150 days following a SARS-CoV-2 test compared with hospitalized individuals with a negative test. Hospitalized adults with a positive test also had increased odds of being diagnosed with ≥ 3 symptoms or fatigue compared with those testing negative. The risks of being newly diagnosed with type 1 or type 2 diabetes (adjusted hazard ratio[aHR], 1.25[95% CI, 1.17-1.33]), hematologic disorders (aHR, 1.19[95% CI, 1.11-1.28]), or respiratory disease (aHR, 1.44[95% CI, 1.30-1.60]) were higher among hospitalized adults with a positive test compared with those with a negative test. Non-hospitalized adults with a positive test also had higher odds or increased risk of being diagnosed with certain symptoms or conditions. CONCLUSIONS: Patients with SARS-CoV-2 infection, especially those who were hospitalized, were at higher risk of being diagnosed with certain symptoms and conditions after acute infection.
