Abstract
Introduction Acquired rifamycin resistance (ARR) in tuberculosis (TB) has been associated with HIV infection and can necessitate complicated TB treatment regimens, particularly in people living with HIV (PLWH). This work examines clinical characteristics and treatment outcomes of PLWH who developed ARR from 2001 to 2023 in New York City (NYC) to inform best practices for treating these patients. Methods PLWH who developed ARR 2001-2023 were identified from the NYC TB registry. Results Sixteen PLWH developed ARR; 15 were diagnosed 2001-2009 and the 16th was diagnosed in 2017. Median CD4 count was 48/mm3. On initial presentation, 14 had positive sputum cultures; of these, 12 culture-converted prior to developing ARR. Ten patients completed a course of TB treatment but subsequently relapsed; in six of these cases, ARR was discovered upon relapse, triggering treatment with a non-rifamycin-containing regimen, while in the other four, ARR was discovered during a second round of rifamycin-containing treatment. Three patients were lost to follow-up during their initial course of TB treatment and later returned to care; after being restarted on a rifamycin-containing regimen, ARR was discovered. Finally, three patients culture-converted during their first course of treatment but subsequently had cultures that grew rifamycin-resistant Mycobacterium tuberculosis prior to treatment completion, leading to changes in their treatment regimens. Among the 16 patients, eight died before being cured of TB, seven successfully completed treatment, and one was lost to follow-up. Conclusions PLWH should be monitored closely for the development of ARR during treatment for TB, and sputum culture conversion should be interpreted cautiously in this group. Collecting a final sputum sample may be especially important for PLWH, as treatment failure and relapse were common in this population. The decrease in the number of cases of ARR among PLWH during the study period may reflect the decrease in the total number of PLWH diagnosed with TB in NYC in recent years, improved immune status of PLWH due to increased uptake of antiretroviral drugs, and improvements in the way anti-TB regimens are designed for PLWH (such as recommending daily rather than intermittent rifamycin dosing).

Immunovirological status in people with perinatal and adult-acquired HIV-1 infection: a multi-cohort analysis from France. THE LANCET REGIONAL HEALTH. EUROPE 2024; 40:100885. [PMID: 38576825 PMCID: PMC10993179 DOI: 10.1016/j.lanepe.2024.100885] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 02/16/2024] [Accepted: 02/26/2024] [Indexed: 04/06/2024]
Abstract
Background No study has compared the virological and immunological status of young people with perinatally-acquired HIV infection (P-HIV) with that of people with HIV adulthood (A-HIV) having a similar duration of infection. Methods 5 French cohorts of P-HIV and A-HIV patients with a known date of HIV-infection and receiving antiretroviral treatment (ART), were used to compare the following proportions of: virological failure (VF) defined as plasma HIV RNA ≥ 50 copies/mL, CD4 cell percentages and CD4:CD8 ratios, at the time of the most recent visit since 2012. The analysis was stratified on time since infection, and multivariate models were adjusted for demographics and treatment history. Findings 310 P-HIV were compared to 1515 A-HIV (median current ages 20.9 [IQR:14.4-25.5] and 45.9 [IQR:37.9-53.5] respectively). VF at the time of the most recent evaluation was significantly higher among P-HIV (22.6%, 69/306) than A-HIV (3.3%, 50/1514); p ≤ 0.0001. The risk of VF was particularly high among the youngest children (2-5 years), adolescents (13-17 years) and young adults (18-24 years), compared to A-HIV with a similar duration of infection: adjusted Odds-Ratio (aOR) 7.0 [95% CI: 1.7; 30.0], 11.4 [4.2; 31.2] and 3.3 [1.0; 10.8] respectively. The level of CD4 cell percentages did not differ between P-HIV and A-HIV. P-HIV aged 6-12 and 13-17 were more likely than A-HIV to have a CD4:CD8 ratio ≥ 1: 84.1% vs. 58.8% (aOR = 3.5 [1.5; 8.3]), and 60.9% vs. 54.7% (aOR = 1.9 [0.9; 4.2]) respectively. Interpretation P-HIV were at a higher risk of VF than A-HIV with a similar duration of infection, even after adjusting for treatment history, whereas they were not at a higher risk of immunological impairment. Exposure to viral replication among young patients living with HIV since birth or a very early age, probably because of lower adherence, could have an impact on health, raising major concerns about the selection of resistance mutations and the risk of HIV transmission.

What's in Your Dataset? Measuring Engagement in HIV Care Using Routinely Administered Items with a Population Disproportionately Burdened by HIV. AIDS Behav 2024; 28:1423-1434. [PMID: 38150065 DOI: 10.1007/s10461-023-04229-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/20/2023] [Indexed: 12/28/2023]
Abstract
We evaluated the psychometric properties of a measure consisting of items that assess current HIV care continuum engagement based on established definitions in the United States. At baseline, participants in this longitudinal study, which included three time points from 2015 to 2020, were 331 young Black sexual minority men ages 18-29 living with HIV in the southern United States residing in two large southern cities. Self-report items reflected four aspects of HIV care continuum engagement as binary variables: seeing a healthcare provider for HIV care, being on antiretroviral treatment, being retained in HIV care, and being virally suppressed. Of these, the following three variables loaded onto a single factor in exploratory factor analysis: being on antiretroviral treatment, being retained in HIV care, and being virally suppressed. A one-dimensional factor structure was confirmed using confirmatory factor analyses at separate time points. Additionally, the three items collectively showed measurement invariance by age, education level, employment status, and income level. The three-item measure also showed reliability based on coefficient omega and convergent validity in its associations with indicators of socioeconomic distress, depression, resilience, and healthcare empowerment. In sum, the items performed well as a single scale. The study demonstrated the potential psychometric strength of simple, feasible, commonly administered items assessing engagement in the HIV care continuum.

Hospital Readmissions Among Persons With Human Immunodeficiency Virus in the United States and Canada, 2005-2018: A Collaboration of Cohort Studies. J Infect Dis 2023; 228:1699-1708. [PMID: 37697938 PMCID: PMC10733730 DOI: 10.1093/infdis/jiad396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 08/25/2023] [Accepted: 09/08/2023] [Indexed: 09/13/2023] Open
Abstract
BACKGROUND Hospital readmission trends for persons with human immunodeficiency virus (PWH) in North America in the context of policy changes, improved antiretroviral therapy (ART), and aging are not well-known. We examined readmissions during 2005-2018 among adult PWH in NA-ACCORD. METHODS Linear risk regression estimated calendar trends in 30-day readmissions, adjusted for demographics, CD4 count, AIDS history, virologic suppression (<400 copies/mL), and cohort. RESULTS We examined 20 189 hospitalizations among 8823 PWH (73% cisgender men, 38% White, 38% Black). PWH hospitalized in 2018 versus 2005 had higher median age (54 vs 44 years), CD4 count (469 vs 274 cells/μL), and virologic suppression (83% vs 49%). Unadjusted 30-day readmissions decreased from 20.1% (95% confidence interval [CI], 17.9%-22.3%) in 2005 to 16.3% (95% CI, 14.1%-18.5%) in 2018. Absolute annual trends were -0.34% (95% CI, -.48% to -.19%) in unadjusted and -0.19% (95% CI, -.35% to -.02%) in adjusted analyses. By index hospitalization reason, there were significant adjusted decreases only for cardiovascular and psychiatric hospitalizations. Readmission reason was most frequently in the same diagnostic category as the index hospitalization. CONCLUSIONS Readmissions decreased over 2005-2018 but remained higher than the general population's. Significant decreases after adjusting for CD4 count and virologic suppression suggest that factors alongside improved ART contributed to lower readmissions. Efforts are needed to further prevent readmissions in PWH.

Assessing the associations between known genetic variants and substance use in people with HIV in the United States. PLoS One 2023; 18:e0292068. [PMID: 37796845 PMCID: PMC10553320 DOI: 10.1371/journal.pone.0292068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Accepted: 09/05/2023] [Indexed: 10/07/2023] Open
Abstract
BACKGROUND The prevalence of substance use in people with HIV (PWH) in the United States is higher than in the general population and is an important driver of HIV-related outcomes. We sought to assess if previously identified genetic associations that contribute to substance use are also observed in a population of PWH. METHODS We performed genome-wide association studies (GWAS) of alcohol, smoking, and cannabis use phenotypes in a multi-ancestry population of 7,542 PWH from the Center for AIDS Research Network of Integrated Clinical Systems (CNICS). We conducted multi-ancestry GWAS for individuals of African (n = 3,748), Admixed American (n = 1,334), and European (n = 2,460) ancestry. Phenotype data were self-reported and collected using patient reported outcomes (PROs) and three questions from AUDIT-C, an alcohol screening tool. We analyzed nine phenotypes: 1) frequency of alcohol consumption, 2) typical number of drinks on a day when drinking alcohol, 3) frequency of five or more alcoholic drinks in a 30-day period, 4) smoking initiation, 5) smoking cessation, 6) cigarettes per day, 7) cannabis use initiation, 8) cannabis use cessation, 9) frequency of cannabis use during the previous 30 days. For each phenotype we considered a) variants previously identified as associated with a substance use trait and b) novel associations. RESULTS We observed evidence for effects of previously reported single nucleotide polymorphisms (SNPs) related to alcohol (rs1229984, p = 0.001), tobacco (rs11783093, p = 2.22E-4), and cannabis use (rs2875907, p = 0.005). We also report two novel loci (19p13.2, p = 1.3E-8; and 20p11.21, p = 2.1E-8) associated with cannabis use cessation. CONCLUSIONS Our analyses contribute to understanding the genetic bases of substance use in a population with relatively higher rates of use compared to the general population.

Cytogenetic changes in oral mucosal cells of human immunodeficiency virus-infected children and adolescents undergoing antiretroviral treatment. REVISTA DA ASSOCIACAO MEDICA BRASILEIRA (1992) 2023; 69:e20230397. [PMID: 37729225 PMCID: PMC10511285 DOI: 10.1590/1806-9282.20230397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Accepted: 07/23/2023] [Indexed: 09/22/2023]
Abstract
OBJECTIVE The objective of this study was to evaluate possible cytogenetic changes in children and adolescents with human immunodeficiency virus on antiretroviral therapy, through the micronucleus test in oral mucosa. METHODS This was a prospective study consisted of 40 individuals, of whom 21 comprised the human immunodeficiency virus group and 19 comprised the control group. Children and adolescents with human immunodeficiency virus were enrolled. The inclusion criteria were <18 years old and consent in participating in the study. The exclusion criteria were the presence of numerous systemic comorbidities, oral lesions, the habit of smoking, alcohol consumption, and X-rays or CT scans taken within 15 days prior to sample collection. A gentle scraping was performed on the inner portion of the jugal mucosa on both sides. A total of 2,000 cells per slide were analyzed for the determination of mutagenicity parameters as follows: micronuclei, binucleation, and nuclear buds. For measuring cytotoxicity, the following metanuclear changes were evaluated: pyknosis, karyolysis, and karyorrhexis, in a double-blind manner. The repair index was also evaluated in this setting. RESULTS The human immunodeficiency virus group showed high frequencies of micronuclei (p=0.05), binucleated cells (p=0.001), and nuclear buds (p=0.03). In the cytotoxicity parameters, represented by the cell death phases, there was an increase with statistical difference (p≤0.05) in the karyorrhexis frequency (p=0.05). Additionally, repair index was decreased in the human immunodeficiency virus group. CONCLUSION These results indicate that human immunodeficiency virus -infected individuals undergoing antiretroviral therapy have cytogenetic changes in oral mucosal cells.

Preference for daily oral pills over long-acting antiretroviral therapy options among people with HIV. AIDS 2023; 37:1545-1553. [PMID: 37289570 PMCID: PMC10355802 DOI: 10.1097/qad.0000000000003620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Accepted: 05/04/2023] [Indexed: 06/10/2023]
Abstract
OBJECTIVE To examine the characteristics of people with HIV (PWH) who prefer remaining on daily oral antiretroviral therapy (ART), rather than switching to long-acting ART (LA-ART). DESIGN Building upon a discrete choice experiment (DCE), we examined characteristics of individuals who always selected their current daily oral tablet regimen over either of two hypothetical LA-ART options presented in a series of 17 choice tasks. METHODS We used LASSO to select sociodemographic, HIV-related, and other health-related predictors of preferring current therapy over LA-ART, and logistic regression to measure the associations with those characteristics. RESULTS Among 700 PWH in Washington State and Atlanta, Georgia, 11% of participants ( n = 74) chose their current daily treatment over LA-ART in all DCE choice tasks. We found that people with lower educational attainment, good adherence, more aversion to injections, and who participated from Atlanta to be more likely to prefer their current daily regimen over LA-ART. CONCLUSIONS Gaps in ART uptake and adherence remain, and emerging LA-ART treatments show promise to address these challenges and help a larger portion of PWH to achieve viral suppression, but preferences for these new treatments are understudied. Our results show that certain drawbacks of LA-ART may help to maintain demand for daily oral tablets, especially for PWH with certain characteristics. Some of these characteristics (lower educational attainment and Atlanta participation) were also associated with a lack of viral suppression. Future research should focus on overcoming barriers that impact preferences for LA-ART among those patients who could benefit most from this innovation.

Abstract
OBJECTIVE The aim of this study was to examine drivers of durable viral suppression (DVS) disparities among people with HIV (PWH) using quantitative intersectional approaches. DESIGN A retrospective cohort analysis from electronic health records informed by intersectionality to better capture the concept of interlocking and interacting systems of oppression. METHODS We analyzed data of PWH seen at a LGBTQ federally qualified health center in Chicago (2012-2019) with at least three viral loads. We identified PWH who achieved DVS using latent trajectory analysis and examined disparities using three intersectional approaches: Adding interactions, latent class analysis (LCA), and qualitative comparative analysis (QCA). Findings were compared with main effects only regression. RESULTS Among 5967 PWH, 90% showed viral trajectories consistent with DVS. Main effects regression showed that substance use [odds ratio (OR) 0.56, 0.46-0.68] and socioeconomic status like being unhoused (OR: 0.39, 0.29-0.53), but not sexual orientation or gender identity (SOGI) were associated with DVS. Adding interactions, we found that race and ethnicity modified the association between insurance and DVS ( P for interaction <0.05). With LCA, we uncovered four social position categories influenced by SOGI with varying rates of DVS. For example, the transgender women-majority class had worse DVS rates versus the class of mostly nonpoor white cisgender gay men (82 vs. 95%). QCA showed that combinations, rather than single factors alone, were important for achieving DVS. Combinations vary with marginalized populations (e.g. black gay/lesbian transgender women) having distinct sufficient combinations compared with historically privileged groups (e.g. white cisgender gay men). CONCLUSION Social factors likely interact to produce DVS disparities. Intersectionality-informed analysis uncover nuance that can inform solutions.

Abstract
Outcomes of PWH with unhealthy alcohol use, such as alcohol use reduction or progression to AUD, are not well-known and may differ by baseline patterns of unhealthy alcohol use. Among 1299 PWH screening positive for NIAAA-defined unhealthy alcohol use in Kaiser Permanente Northern California, 2013-2017, we compared 2-year probabilities of reduction to low-risk/no alcohol use and rates of new AUD diagnoses by baseline use patterns, categorized as exceeding: only daily limits (72% of included PWH), only weekly limits (17%), or both (11%), based on NIAAA recommendations. Overall, 73.2% (95% CI 70.5-75.9%) of re-screened PWH reduced to low-risk/no alcohol use over 2 years, and there were 3.1 (95% CI 2.5-3.8%) new AUD diagnoses per 100 person-years. Compared with PWH only exceeding daily limits at baseline, those only exceeding weekly limits and those exceeding both limits were less likely to reduce and likelier to be diagnosed with AUD during follow-up. PWH exceeding weekly drinking limits, with or without exceeding daily limits, may have a potential need for targeted interventions to address unhealthy alcohol use.

Abstract
BACKGROUND The healthcare transition (HCT) from pediatric to adult HIV care can be disruptive to HIV care engagement and viral suppression for youth living with HIV (YLH). METHODS We performed qualitative interviews with 20 YLH who experienced HCT and with 20 multidisciplinary pediatric and adult HIV clinicians to assess and rank barriers and facilitators to HCT and obtain their perspectives on strategies to improve the HCT process. We used the Exploration Preparation Implementation Sustainment Framework to guide this qualitative inquiry. RESULTS The most impactful barriers identified by YLH and clinicians focused on issues affecting the patient-clinician relationship, including building trust, and accessibility of clinicians. Both groups reported that having to leave the pediatric team was a significant barrier (ranked #1 for clinicians and #2 for YLH). The most impactful facilitator included having a social worker or case manager to navigate the HCT (listed #1 by clinicians and #2 by YLH); case managers were also identified as the individual most suited to support HCT. While YLH reported difficulty building trust with their new clinician as their #1 barrier, they also ranked the trust they ultimately built with a new clinician as their #1 facilitator. Factors reported to bridge pediatric and adult care included providing a warm handoff, medical record transfer, developing relationships between pediatric clinics and a network of youth-friendly adult clinics, and having the pediatric case manager attend the first adult appointment. Longer new patient visits, increased health communication between YLH and clinicians and sharing vetted clinician profiles with YLH were identified as innovative strategies. CONCLUSION In this multi-disciplinary contextual inquiry, we have identified several determinants that may be targeted to improve HCT for YLH.

Abstract
INTRODUCTION Young adults with vertical transmission (VT) of human immunodeficiency virus (HIV) represent a fragile population. This study evaluates factors associated with viro-immunological outcome of these patients. METHODS We performed a multicenter study including HIV-infected subjects with VT ≥ 18 years old from six Italian clinics. Subjects were observed from birth to death, lost to follow-up, or last visit until December 31, 2019. Condition of "optimal viro-immunological status" (OS) was defined as the simultaneous presence of HIV ribonucleic acid (RNA) < 50 copies/mL, CD4+ > 500 cells/mm3 , and CD4+/CD8+ ratio ≥ 1. RESULTS A total of 126 subjects were enrolled. At 18 years of age, 52/126 (44.4%) had HIV-RNA > 50 copies/mL, 47/126 (38.2%) had CD4+ < 500/mm3 , and 78/126 (67.2%) had CD4+/CD8+ < 1; 28 subjects (23.7%) presented in the condition of OS. Having a CD4+/CD8+ ratio ≥ 1 at 18 years of age was related with an increased probability of shift from suboptimal viro-immunological status (SOS) to OS (HR: 7.7, 95% confidence interval [CI]: 4.23-14.04), and a reduced risk of shift from the OS to the SOS (HR: 0.49, 95% CI: 0.26-0.92). Acquired immunodeficiency syndrome (AIDS) diagnosis significantly reduced the probability of shift from a viro-immunological SOS to OS (HR: 0.09, 95% CI: 0.03-0.30). Subjects who had not achieved an OS at 18 years of age had an increased risk of discontinuation of combination antiretroviral therapy (cART, p = .019). CONCLUSIONS Only a small proportion of subjects with VT of HIV reached the adult age with "OS". Transition to the adult care with a compromised viro-immunological condition represents a negative driver for future optimal infection control, with a higher risk of discontinuation of cART and a reduced probability to improve the immunological status later in the years.

Abstract
Background Human immunodeficiency virus (HIV) and psychosis share a complex bidirectional relationship, with people living with HIV being at increased risk of psychosis and those with psychosis at increased risk of HIV. However, people living with severe mental illness often have limited or reduced access to HIV testing and care. Aim This study aimed to determine the prevalence of HIV and describe the access to HIV testing and care among adult patients with recent-onset psychosis who were admitted to a psychiatric hospital in KwaZulu-Natal (KZN) province, South Africa. Setting A psychiatric hospital in Pietermaritzburg, KZN province, South Africa. Method A retrospective chart review of 294 patients with recent-onset psychosis admitted between May 2018 and November 2020. Results A total of 291 (99%) patients had access to HIV testing during the study period, with the HIV seroprevalence rate being 21.5% among the 294 patients; HIV seropositivity was associated with the 25-49 age category (adjusted odds ratio [aOR] = 3.09, 95% confidence interval [CI] 1.27-7.50), female gender (aOR = 9.55, 95% CI 4.40-20.74), current alcohol and cannabis use (aOR = 3.43, 95% CI 1.01-11.62), family history of psychosis (aOR = 3.22, 95% CI 1.03-10.02) and no tertiary education (aOR = 3.7, 95% CI 0.14-0.99). All those living with HIV were on antiretroviral treatment. Conclusion This study showed that HIV testing and care was accessible at a psychiatric hospital but the prevalence of HIV in people living with recent onset psychosis remains high. Contribution The study findings suggest the importance of integrating mental health and HIV management.

Abstract
Background Viral suppression is the ultimate goal of the HIV treatment cascade and a primary endpoint of antiretroviral therapy. Empirical evidence found racial/ethnic disparities in viral suppression among people living with HIV (PWH), but the evidence of the relationship between racial/ethnic residential segregation and place-based viral suppression is scarce. Further exploring potential structural moderators in this relationship has substantial implications for healthcare policymaking and resource allocation. The current study aimed to investigate the spatial-temporal disparities in the HIV viral suppression rate across 46 counties in South Carolina from 2013 to 2018. We also examined the impact of racial/ethnic residential segregation and the moderation effect of community health, one measurement of community engagement and volunteerism. Methods The proportion of PWH who achieved viral suppression for each county and calendar year was calculated using de-identified electronic medical records. The isolation index was calculated and used to measure racial/ethnic residential segregation. The community health index and other county-level factors were directly extracted from multiple publicly available datasets. We used geospatial mapping to explore the spatial-temporal variations of HIV viral suppression rates. Hierarchical quasi-binominal regression models were used to examine the impacts of racial/ethnic residential segregation on county-level viral suppression rate by the extent of community health. Results From 2013 to 2018, the average viral suppression rate across 46 counties in SC increased from 64.3% to 65.4%. Regression results revealed that counties with high racial/ethnic residential segregation were more likely to have a low viral suppression rate (β = -0.56, 95% CI: -0.75 to -0.37). In counties with high levels of community health, the impact of racial/ethnic residential segregation on viral suppression rate decreased as compared with those with low levels of community health (β = 5.50, 95% CI: 0.95-10.05). Conclusions Racial/ethnic residential segregation acts as a structural barrier to placed-based viral suppression rates and compromises the goal of the HIV treatment cascade. Concentrated and sustained county-level interventions aiming to improve community health can be practical approaches to promote health equity in HIV treatment and care.

Abstract
Describe health of transgender women (TW) with HIV vs. cisgender men and women (CM, CW) in a U.S. HIV care cohort. Data were from Centers for AIDS Research Network of Integrated Clinical Systems (CNICS), 2005-2022. TW were identified using clinical data/identity measures. PWH (n = 1285) were included in analyses (275 TW, 547 CM, 463 CW). Cross-sectional multivariable analyses compared HIV outcomes/co-morbidities between TW/CM and TW/CW, and adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) were estimated. TW had poorer adherence (> 90% adherent; aOR 0.57; 95%CI 0.38, 0.87) and were more likely to miss ≥ 3 visits in the past year than CM (aOR 1.50, 95%CI 1.06, 2.10); indicated more anxiety compared to both CM and CW (p ≤ 0.001, p = 0.02); hepatitis C infection (p = 0.03) and past-year/lifetime substance treatment (p = 0.004/p = 0.001) compared to CM; and substance use relative to CW. TW with HIV differed in HIV clinical outcomes and co-morbidities from CM and CW.

Abstract
OBJECTIVE To elucidate how and in what ways cumulative violence affects health-related quality of life (HRQoL) among a clinical cohort of virally stable people living with HIV. DESIGN We used data from the University of North Carolina Center for AIDS Research HIV clinical cohort. Our analysis was limited to participants with an undetectable viral load (<200) and those who completed the Clinical, Sociodemographic, and Behavioral Survey between 2008 and 2017 ( n = 284). METHODS A path analysis was used to test our primary hypothesis that the effect of cumulative violence on HRQoL would be mediated through symptoms of post-traumatic stress disorder (PTSD), depressive symptoms, and HIV symptom distress. RESULTS The impact of cumulative violence on HRQoL was fully mediated by symptoms of PTSD, depressive symptoms, and HIV symptom distress. Greater exposure to violence was associated with higher odds of PTSD symptoms ( P <0.001), increased depressive symptoms ( P <0.001), and increased HIV symptom distress ( P < 0.01). HIV symptom distress displayed the largest association with HRQoL ( P < 0.001), followed by depressive symptoms ( P = 0.001) and PTSD symptoms ( P < 0.001). These factors explained approximately 51% of the variance in HRQoL ( R2 = 0.51, P < 0.001). CONCLUSIONS Our findings indicate that addressing physical and mental health symptoms rooted in violent victimization should be a point of focus in efforts to improve HRQoL among people living with HIV who are virally stable.

Abstract
Aboriginal and Torres Strait Islander (hereafter Aboriginal) people are a priority population for HIV care in Australia; however, no HIV cascade exists for this population. We developed annual HIV cascades for 2010-2017 specific to Aboriginal peoples. By 2017, an estimated 595 Aboriginal people were living with HIV (PLWH); however, 14% remained undiagnosed. Cascade steps below global targets were: PLWH aware of their diagnosis (86%), and retention in care (81% of those who had received any care in previous two years in a sentinel network of clinics). For people retained in care, treatment outcomes surpassed global targets (92% receiving treatment, 93% viral suppression). Increases occurred across all HIV cascade steps over time; however, the least improvement was for retention in care, while the greatest improvement was achieving viral suppression. The HIV cascade for Aboriginal peoples highlights both gaps and strengths in the Australian HIV care system, and importantly highlights where potential interventions may be required to achieve the global UNAIDS targets.

Abstract
Universal substance use screening in primary care can proactively identify patients for intervention, though implementation is challenging. This project developed a strategy for universal low time- and labor-cost screening, brief intervention, and referral for treatment (SBIRT) in an HIV primary care clinic at an academic medical center in the Southeastern USA. Screening was implemented using a tablet computer that calculated results in real time and suggested motivational language for provider response. A brief intervention (BNI) was conducted by a trained professional as needed, preventing the need for all clinic providers to be competent in motivational interviewing (MI). More than 1868 patients were screened in 12 months, with an MI intervention conducted for 101 patients with higher risk use. Forty-four patients were referred for in-clinic treatment, compared to nine in the previous year. Computer-based, self-administered screening with real-time linkage to a BNI can allow recommended screening with low provider burden.

Abstract
BACKGROUND We compared weight changes in virally suppressed people living with HIV (PLWH) switching to integrase strand transfer inhibitors (INSTIs) with those remaining on an INSTI or non-INSTI regimen. METHODS PLWH aged ≥18 years with weight measurements available at baseline between 2001 and 2020 were included. Viral suppression was defined as having had a viral load <400 copies/mL for 6 months. Baseline was defined as the time of switching from a non-INSTI to an INSTI regimen whilst virally suppressed (switch group) or the time that viral suppression was achieved (remain groups). Generalized estimating equations adjusted for age, sex and baseline weight were used to model weight changes 6, 12, 18 and 24 months after baseline. RESULTS A total of 1673 PLWH contributed 1952 episodes of viral suppression-143 (7.3%) episodes were among PLWH who had switched from a non-INSTI to an INSTI, 102 (5.2%) episodes were among PLWH who remained on an INSTI and 1707 (87.4%) episodes were among PLWH who remained on a non-INSTI. PLWH in the switch group had significantly greater weight gain than those in the remain groups at 6, 12 and 18 months after achieving viral suppression. By 24 months, weight change on all regimens started to converge. Tenofovir alafenamide use was not significantly associated with weight gain in adjusted models. CONCLUSIONS Our findings suggest that the mechanisms of weight gain due to INSTI use go beyond their superior efficacy over other antiretrovirals in controlling HIV or the effect of the 'return-to-health' phenomenon. Further research is needed to understand the mechanisms of such weight gain.

Abstract
Background Medically vulnerable individuals are at increased risk of acquiring multidrug-resistant Enterobacterales (MDR-E) infections. People with HIV (PWH) experience a greater burden of comorbidities and may be more susceptible to MDR-E due to HIV-specific factors. Methods We performed an observational study of PWH participating in an HIV clinical cohort and engaged in care at a tertiary care center in the Southeastern United States from 2000 to 2018. We evaluated demographic and clinical predictors of MDR-E by estimating prevalence ratios (PRs) and employing machine learning classification algorithms. In addition, we created a predictive model to estimate risk of MDR-E among PWH using a machine learning approach. Results Among 4734 study participants, MDR-E was isolated from 1.6% (95% CI, 1.2%-2.1%). In unadjusted analyses, MDR-E was strongly associated with nadir CD4 cell count ≤200 cells/mm3 (PR, 4.0; 95% CI, 2.3-7.4), history of an AIDS-defining clinical condition (PR, 3.7; 95% CI, 2.3-6.2), and hospital admission in the prior 12 months (PR, 5.0; 95% CI, 3.2-7.9). With all variables included in machine learning algorithms, the most important clinical predictors of MDR-E were hospitalization, history of renal disease, history of an AIDS-defining clinical condition, CD4 cell count nadir ≤200 cells/mm3, and current CD4 cell count 201-500 cells/mm3. Female gender was the most important demographic predictor. Conclusions PWH are at risk for MDR-E infection due to HIV-specific factors, in addition to established risk factors. Early HIV diagnosis, linkage to care, and antiretroviral therapy to prevent immunosuppression, comorbidities, and coinfections protect against antimicrobial-resistant bacterial infections.

Abstract
OBJECTIVE Depression, substance use disorders, and other neuropsychiatric comorbidities are common in people with HIV (PWH), but the underlying mechanisms are not sufficiently understood. HIV-induced damage to the gastrointestinal tract potentiates residual immune dysregulation in PWH receiving effective antiretroviral therapy. However, few studies among PWH have examined the relevance of microbiome-gut-brain axis: bidirectional crosstalk between the gastrointestinal tract, immune system, and central nervous system. METHODS A narrative review was conducted to integrate findings from 159 articles relevant to psychoneuroimmunology (PNI) and microbiome-gut-brain axis research in PWH. RESULTS Early PNI studies demonstrated that neuroendocrine signaling via the hypothalamic-pituitary-adrenal axis and autonomic nervous system could partially account for the associations of psychological factors with clinical HIV progression. This review highlights the need for PNI studies examining the mechanistic relevance of the gut microbiota for residual immune dysregulation, tryptophan catabolism, and oxytocin release as key biological determinants of neuropsychiatric comorbidities in PWH (i.e., body-to-mind pathways). It also underscores the continued relevance of neuroendocrine signaling via the hypothalamic-pituitary-adrenal axis, autonomic nervous system, and oxytocin release in modifying microbiome-gut-brain axis functioning (i.e., mind-to-body pathways). CONCLUSIONS Advancing our understanding of PNI and microbiome-gut-brain axis pathways relevant to depression, substance use disorders, and other neuropsychiatric comorbidities in PWH can guide the development of novel biobehavioral interventions to optimize health outcomes. Recommendations are provided for biobehavioral and neurobehavioral research investigating bidirectional PNI and microbiome-gut-brain axis pathways among PWH in the modern antiretroviral therapy era.

Abstract
Black/African American (Black) versus White persons are unequally burdened by human immunodeficiency virus (HIV) in the United States. Structural factors can influence social determinants of health, key components in reducing HIV-related health inequality by race. This analysis examined HIV care outcomes among Black and White persons with diagnosed HIV (PWDH) in relation to three structural factors: racial redlining, Medicaid expansion, and Ryan White HIV/AIDS Program (RWHAP) use. Using National HIV Surveillance System, U.S. Census, and Home Mortgage Disclosure Act data, we examined linkage to HIV care and viral suppression (i.e., viral load < 200 copies/mL) in relation to the structural factors among 12,996 Black and White PWDH with HIV diagnosed in 2017/alive at year-end 2018, aged ≥ 18 years, and residing in 38 U.S. jurisdictions with complete laboratory data, geocoding, and census tract-level redlining indexes. Compared to White PWDH, a lower proportion of Black PWDH were linked to HIV care within 1 month after diagnosis and were virally suppressed in 2018. Redlining was not associated with the HIV care outcomes. A higher prevalence of PWDH residing (v. not residing) in states with Medicaid expansion were linked to HIV care ≤ 1 month after diagnosis. A higher prevalence of those residing (v. not residing) in states with > 50% of PWDH in RWHAP had viral suppression. Direct exposure to redlining was not associated with poor HIV care outcomes. Structural factors that reduce the financial burden of HIV care and improve care access like Medicaid expansion and RWHAP might improve HIV care outcomes of PWDH.

Abstract
BACKGROUND Urban Black gay, and bisexual men (MSM) bear a disproportionate burden of HIV in the U.S. Mental health is a barrier to adherence to both antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP). The objective was to determine the association between psychological distress and ART or PrEP adherence among urban Black MSM. METHODS Using data from a four-year prospective cohort study, adherence to ART was defined as > 95% and PrEP was defined as > 80% of doses taken in the past 30 days. Psychological distress measures included difficulty sleeping; feeling anxious; suicidality; feeling sad or depressed; feeling sick, ill, or not well in the past 3 months; high (vs. low) overall psychological distress was classified as above the median value. Associations were examined using Chi-square, Fisher's exact tests, and logistic regression. RESULTS Among 165 Black MSM, 44.2% (73) reported high psychological distress. 65.3% (47/72) of participants living with HIV and 39.8% (37/93) of HIV negative participants were ART or PrEP adherent, respectively. Education was significantly associated with PrEP adherence (p = 0.038). Non-injection drug use in the past 3 months (p = 0.008), difficulty sleeping (p = 0.010), feeling anxious (p = 0.003), and feeling sad or depressed (p < 0.001), and overall psychological distress (p < 0.001) were significantly associated with ART adherence. High psychological distress was significantly associated with a reduced odds of ART adherence (aOR 0.23; 95% CI = 0.08-0.70) adjusting for age and non-injection drug use. CONCLUSIONS Increased psychological distress was significantly associated with ART nonadherence and may represent an important barrier to viral suppression.

Abstract
BACKGROUND Approximately 1.1 million people living with HIV live in the United States, and the incidence is highest in Southeastern United States. Electronic patient portal prevalence is increasing and can improve engagement in primary medical care. Retention in care and viral suppression-measures of engagement in HIV care-are associated with decreased HIV transmission, morbidity, and mortality. OBJECTIVE We aimed to determine if patient portal access among people living with HIV was associated with retention and viral suppression. METHODS We conducted an observational cohort study among people living with HIV in care at the Vanderbilt Comprehensive Care Clinic (Nashville, Tennessee) from 2011-2016. Individual access was defined as patient portal account registration at any point in the year prior. Retention was defined as ≥2 kept appointments or HIV lab measurements ≥3 months apart within a 12-month period. Viral suppression was defined as the last viral load in the calendar year <200 copies/mL. We calculated adjusted prevalence ratios (aPRs) and 95% CIs using modified Poisson regression with generalized estimating equations to estimate the association of portal access with retention and viral suppression. RESULTS We included 4237 people living with HIV contributing 16,951 person-years of follow-up (median 5, IQR 3-5 person-years). The median age was 43 (IQR 33-50) years. Of the 4237 people living with HIV, 78.1% (n=4237) were male, 40.8% (n=1727) were Black non-Hispanic, and 56.5% (n=2395) had access. Access was independently associated with retention (aPR 1.13, 95% CI 1.10-1.17) and viral suppression (aPR 1.18, 95% CI 1.14-1.22). CONCLUSIONS In this population, patient portal access was associated with retention and viral suppression. Future prospective studies should assess the impact of increasing portal access among people living with HIV on these HIV outcomes.

Abstract
Background Only a few recent reports have examined longitudinal adherence patterns in US clinics and its impact on immunological and virological outcomes among large cohorts initiating contemporary antiretroviral therapy (ART) in US clinics. Methods We followed all persons with HIV (PLWH) in a California clinic population initiating ART between 2010 and 2017. We estimated longitudinal adherence for each PLWH by calculating the medication possession ratio within multiple 6-month intervals using pharmacy refill records. Results During the study, 2315 PWLH were followed for a median time of 210.8 weeks and only 179 (7.7%) were lost-to-follow-up. The mean adherence was 84.9%. Age (Hazard Ratio (HR): (95% confidence interval): 1.25 (1.20–1.31) per 10-year increase) and Black race (HR: 0.62 (0.53–0.73) vs. White) were associated with adherence in the cohort. A 10% percent increase in adherence increased the odds of being virally suppressed by 37% (OR and 95% CI: 1.37 [1.33–1.41]) and was associated with an increase in mean CD4 count by 8.54 cells/ul in the next 6-month interval (p-value <0.0001). Conclusions Our study shows that despite large improvements in retention in care, demographic disparities in adherence to ART persist. Adherence was lower among younger patients and black patients. Our study confirmed the strong association between adherence to ART and viral suppression but could only establish a weak association between adherence and CD4 count. These findings reaffirm the importance of adherence and retention in care and further highlight the need for tailored patient-centered HIV Care Models as a strategy to improve PLWH’s outcomes.

Studying patterns and predictors of HIV viral suppression using A Big Data approach: a research protocol. BMC Infect Dis 2022; 22:122.

Abstract
Background Given the importance of viral suppression in ending the HIV epidemic in the US and elsewhere, an optimal predictive model of viral status can help clinicians identify those at risk of poor viral control and inform clinical improvements in HIV treatment and care. With an increasing availability of electronic health record (EHR) data and social environmental information, there is a unique opportunity to improve our understanding of the dynamic pattern of viral suppression. Using a statewide cohort of people living with HIV (PLWH) in South Carolina (SC), the overall goal of the proposed research is to examine the dynamic patterns of viral suppression, develop optimal predictive models of various viral suppression indicators, and translate the models to a beta version of service-ready tools for clinical decision support. Methods The PLWH cohort will be identified through the SC Enhanced HIV/AIDS Reporting System (eHARS). 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. Using the deidentified data, the proposed study will consist of three operational phases: Phase 1: “Pattern Analysis” to identify the longitudinal dynamics of viral suppression using multiple viral load indicators; Phase 2: “Model Development” to determine the critical predictors of multiple viral load indicators through artificial intelligence (AI)-based modeling accounting for multilevel factors; and Phase 3: “Translational Research” to develop a multifactorial clinical decision system based on a risk prediction model to assist with the identification of the risk of viral failure or viral rebound when patients present at clinical visits. Discussion With both extensive data integration and data analytics, the proposed research will: (1) improve the understanding of the complex inter-related effects of longitudinal trajectories of HIV viral suppressions and HIV treatment history while taking into consideration multilevel factors; and (2) develop empirical public health approaches to achieve ending the HIV epidemic through translating the risk prediction model to a multifactorial decision system that enables the feasibility of AI-assisted clinical decisions.

Abstract
Antiretroviral therapy (ART) reduces HIV disease burden, increases life expectancy, and prevents HIV transmission. Previous research suggests that believing that it is harmful to take ART when using substances (i.e., interactive toxicity beliefs) leads to intentional ART nonadherence; however, these associations have not been investigated among younger adults living with HIV and have not been linked to clinical outcomes. We examined the associations among interactive toxicity beliefs, intentional nonadherence, and HIV clinical outcomes in young adults living with HIV. People living with HIV younger than the age of 36 years who tested positive for at least one substance use biomarker (N = 406) completed a 1-month pretrial run-in study that included computerized interviews, substance use biomarkers, HIV viral load, and unannounced pill counts for ART adherence. Analyses compared three HIV clinical outcome groups: (1) HIV viral unsuppressed, (2) HIV viral suppressed and ART nonadherent, and (3) HIV viral suppressed and ART adherent, on substance use, interactive toxicity beliefs, and substance use-related intentional ART nonadherence. Results showed that a majority of participants reported intentional nonadherence. Participants with unsuppressed HIV reported greater interactive toxicity beliefs and intentional nonadherence. We conclude that intentional nonadherence adds to the detrimental impacts of substance use on ART adherence and interactive toxicity beliefs that foster these behaviors may be amenable to interventions.

Abstract
BACKGROUND In 2010, HIV treatment as prevention (TasP), encompassing widespread HIV testing and immediate initiation of free antiretroviral treatment (ART), was piloted under the Seek and Treat for Optimal Prevention of HIV/AIDS initiative (STOP) in British Columbia, Canada. We compared the time from HIV diagnosis to treatment initiation, and from treatment initiation to first virologic suppression, before (2005-2009) and after (2010-2016) the implementation of STOP. METHODS In this population-based cohort study, we used longitudinal data of all people living with an HIV diagnosis in BC from 1996 to 2017. We included those aged 18 years or older who had never received ART and had received an HIV diagnosis in the 2005-2016 period. We defined the virologic suppression date as the first date of at least 2 consecutive test results within 4 months with a viral load of less than 200 copies/mL. Negative binomial regression models assessed the effect of STOP on the time to ART initiation and suppression, adjusting for confounders. All p values were 2-sided, and we set the significance level at 0.05. RESULTS Participants who received an HIV diagnosis before STOP (n = 1601) were statistically different from those with a diagnosis after STOP (n = 1700); 81% versus 84% were men (p = 0.0187), 30% versus 15% had ever injected drugs (p < 0.0001), and 27% versus 49% had 350 CD4 cells/μL or more at diagnosis (p < 0.0001). The STOP initiative was associated with a 64% shorter time from diagnosis to treatment (adjusted mean ratio 0.36, 95% confidence interval [CI] 0.34-0.39) and a 21% shorter time from treatment to suppression (adjusted mean ratio 0.79, 95% CI 0.73-0.85). INTERPRETATION In a population with universal health coverage, a TasP intervention was associated with shorter times from HIV diagnosis to treatment initiation, and from treatment initiation to viral suppression. Our results show accelerating progress toward the United Nations' 90-90-90 target of people with HIV who have a diagnosis, those who are on antiretroviral therapy and those who are virologically suppressed, and support the global expansion of TasP to accelerate the control of HIV/AIDS.

Abstract
Objectives:This study aimed at assessing adherence, effectiveness,
and safety of DTG-based HAART regimens among HIV-infected children and
adolescents in Tanzania. Methods: This was a single-center
prospective cohort study, conducted at the pediatric HIV Clinic in Mbeya,
Tanzania. A binary logistic regression model was used to determine predictors of
undetectable viral load at week 24. The results were significant when P-value
was <0.05. Results: A total of 200 patients were enrolled with
the majority (85.5%) being treatment experienced. High adherence levels (71%)
were observed using the pharmacy refill method. At week 24, the overall
proportion of patients with undetectable viral load was 70.2%. The predictors of
undetectable viral load were age, World Health Organization (WHO) clinical
stage, baseline VL and adherence to pharmacy refill. Conclusion:
The majority of patients attained undetectable viral load 6 months after using
DTG based regimen. DTG-based regimens were generally safe with few ADEs
reported.

Abstract
BACKGROUND Although HIV antiretroviral treatment (ART) access and uptake have increased among racial/ethnic minority individuals, lower rates of ART adherence and viral suppression persist, especially among Black men who have sex with men (BMSM) compared with their White counterparts. SETTING Black men who have sex with men living with HIV (BMSM+) residing in Los Angeles County (N = 124) were recruited in-person (eg, clinic) and online (eg, social networking apps). METHODS Participants completed a cross-sectional survey measuring demographic characteristics, structural syndemics (poverty, criminal justice involvement, and housing instability), and psychosocial syndemics (mental health and substance use). A text message survey assessed missed doses of ART over the past week. Zero-inflated Poisson regression models were used to evaluate variables associated with the number of missed doses of ART. RESULTS On average, participants missed 1.30 doses of ART (SD = 2.09) and reported structural syndemics: poverty (56.1%), criminal justice involvement (36.6%), housing instability (26.3%), and psychosocial syndemics: childhood sexual abuse (51.8%), intimate partner violence (16.9%), depression (39%), and problem alcohol use (15.5%). After controlling for employment, age, education, and psychosocial syndemics, participants with a one-point increase in structural syndemic indicators were found to be 1.63 times more likely to have missed a dose of ART. CONCLUSIONS Structural syndemic were associated with ART nonadherence among BMSM+ after adjusting for demographic and psychosocial factors. HIV treatment interventions that incorporate financial incentives, legal support, and housing may help improve ART adherence among BMSM+. Findings suggest that key priorities to ending the HIV epidemic must include structural interventions that alleviate poverty, eliminate disproportionate policing and criminalization, and end homelessness.

Abstract
This study examined feasibility, acceptability, and preliminary efficacy of an mHealth facilitated health coaching antiretroviral therapy (ART) adherence intervention. Persons living with HIV (n = 53) were randomized to an in-person adherence session and 12 months of app access and health coaching via the app (Fitbit Plus) versus single adherence session (SOC). At baseline and 1, 3, 6, and 12 months, we measured ART adherence, substance use, and depressive symptoms. We also conducted individual qualitative interviews. The intervention was found to be largely feasible and highly acceptable, with the health coach spending an average of 2.4 min per month with a participant and 76.5% of Fitbit Plus participants using the app regularly at 12 months. While most comparisons were not significant, the pattern of results was consistent with better adherence in the Fitbit Plus compared to SOC condition. Substance use was significantly associated with poorer ART adherence while depressive symptoms were not.ClinicalTrials.gov Identifier: NCT02676128; Registered: 2/8/2016.

Abstract
OBJECTIVE To examine changes in the lengths of time from HIV infection to diagnosis (Infx-to-Dx) and from diagnosis to first viral suppression (Dx-to-VS), two periods during which HIV can be transmitted. DESIGN Data from the National HIV Surveillance System (NHSS) for persons who were aged at least 13 years at the time of HIV diagnosis during 2014-2018 and resided in one of 33 United States jurisdictions with complete laboratory reporting. METHODS The date of HIV infection was estimated based on a CD4+-depletion model. Date of HIV diagnosis, and dates and results of first CD4+ test and first viral suppression (<200 copies/ml) after diagnosis were reported to NHSS through December 2019. Trends for Infx-to-Dx and Dx-to-VS intervals were examined using estimated annual percentage change. RESULTS During 2014-2018, among persons aged at least 13 years, 133 413 HIV diagnoses occurred. The median length of infx-to-Dx interval shortened from 43 months (2014) to 40 months (2018), a 1.5% annual decrease (7% relative change over the 5-year period). The median length of Dx-to-VS interval shortened from 7 months (2014) to 4 months (2018), an 11.4% annual decrease (42.9% relative change over the 5-year period). Infx-to-Dx intervals shortened in only some subgroups, whereas Dx-to-VS intervals shortened in all groups by sex, transmission category, race/ethnicity, age, and CD4+ count at diagnosis. CONCLUSION The shortened Infx-to-Dx and Dx-to-VS intervals suggest progress in promoting HIV testing and earlier treatment; however, diagnosis delays continue to be substantial. Further shortening both intervals and eliminating disparities are needed to achieve Ending the HIV Epidemic goals.

Abstract
OBJECTIVE The aim of this study was to describe the risk of viral nonsuppression across the depression care cascade. DESIGN A clinical cohort study. METHODS We used depressive symptoms (PHQ-8 ≥ 10) self-reported on computer-assisted surveys, clinical diagnoses of depression in the medical record in the prior year and pharmacologic (any prescription for an antidepressant) and psychologic treatments for depression (attendance at at least two mental health visits in the prior year) to classify patients into groups: no history of depression; prior depression diagnosis; current indication for depression treatment (symptoms or clinical diagnosis); and treated depression (stratified by presence of persistent symptoms). We associated position in the depression care cascade with viral nonsuppression (>200 copies/ml) 7 days before to 6 months after the index self-report of depressive symptoms. RESULTS History of depression [adjusted risk difference (aRD) relative to no history = 5.9%, 95% confidence interval (95% CI): 1.5-10.3] and current depression (symptoms or diagnosis) in the absence of treatment (aRD relative to no current depression or depression treatment = 4.8%, 95% CI: 1.8-7.8) were associated with a higher risk of viral nonsuppression than no history of depression. Depression treatment mitigated this association (aRD = -0.4%, 95% CI: -2.5 to 1.7). CONCLUSION The relationship between depression care cascade and viral suppression is complex. Untreated depression and clinically unrecognized depressive symptoms were both related to viral nonsuppression. Treated depression was not associated with viral nonsuppression; however, a high proportion of treated patients still had depressive symptoms. Depression treatment should be titrated if patients' symptoms are not responsive and patients with a history of depression should be monitored for ART adherence.

Abstract
Bictegravir, cabotegravir, dolutegravir, elvitegravir, and raltegravir are members of the latest class of antiretrovirals available to treat human immunodeficiency virus (HIV) infection, the integrase strand transfer inhibitors. Integrase strand transfer inhibitors are potent inhibitors of the HIV integrase enzyme with IC90/95 values in the low nanogram per milliliter range and they retain antiviral activity against strains of HIV with acquired resistance to other classes of antiretrovirals. Each of the integrase strand transfer inhibitors have unique pharmacokinetic/pharmacodynamic properties, influencing their role in clinical use in specific subsets of patients. Cabotegravir, approved for use in Canada but not yet by the US Food and Drug Administration, is formulated in both oral and intramuscular formulations; the latter of which has shown efficacy as a long-acting extended-release formulation. Cabotegravir, raltegravir, and dolutegravir have minimal drug-drug interaction profiles, as their metabolism has minimal cytochrome P450 involvement. Conversely, elvitegravir metabolism occurs primarily via cytochrome P450 3A4 and requires pharmacokinetic boosting to achieve systemic exposures amenable to once-daily dosing. Bictegravir metabolism has similar contributions from both cytochrome P450 3A4 and uridine 5'-diphospho-glucuronosyltransferase 1A1. Bictegravir, dolutegravir, and raltegravir are recommended components of initial regimens for most people with HIV in the US adult and adolescent HIV treatment guidelines. This review summarizes and compares the pharmacokinetics and pharmacodynamics of the integrase strand transfer inhibitor agents, and describes specific pharmacokinetic considerations for persons with hepatic impairment, renal dysfunction, pregnancy, and co-infections.

Abstract
OBJECTIVE We investigated differences in clinical outcomes in heterosexual participants, by ethnicity in the UK Collaborative HIV Cohort Study from 2000 to 2017. DESIGN Cohort analysis. METHODS Logistic/proportional hazard regression assessed ethnic group differences in CD4+ cell count at presentation, engagement-in-care, combination antiretroviral therapy (cART) initiation, viral suppression and rebound. RESULTS Of 12 302 participants [median age: 37 (interquartile range: 31-44) years, 52.5% women, total follow-up: 85 846 person-years], 64.4% were black African, 19.1% white, 6.3% black Caribbean, 3.6% black other, 3.3% South Asian/other Asian and 3.4% other/mixed. CD4+ cell count at presentation amongst participants from non-white groups were lower than the white group. Participants were engaged-in-care for 79.6% of follow-up time; however, black and other/mixed groups were less likely to be engaged-in-care than the white group (adjusted odds ratios vs. white: black African: 0.70 (95% confidence interval (CI) 0.63-0.79], black Caribbean: 0.74 (0.63-0.88), other/mixed: 0.78 (0.62-0.98), black other: 0.81 (0.64-1.02)). Of 8867 who started cART, 79.1% achieved viral suppression, with no differences by ethnicity in cART initiation or viral suppression. Viral rebound (22.2%) was more common in the black other [1.95 (1.37-2.77)], black African [1.85 (1.52-2.24)], black Caribbean [1.73 (1.28-2.33)], South Asian/other Asian [1.35 (0.90-2.03)] and other/mixed [1.09 (0.69-1.71)] groups than in white participants. CONCLUSION Heterosexual people from black, Asian and minority ethnic (BAME) groups presented with lower CD4+ cell counts, spent less time engaged-in-care and were more likely to experience viral rebound than white people. Work to understand and address these differences is needed.

Abstract
BACKGROUND Understanding advances in the care and treatment of adults with HIV as well as remaining gaps requires comparing differences in mortality between persons entering care for HIV and the general population. OBJECTIVE To assess the extent to which mortality among persons entering HIV care in the United States is elevated over mortality among matched persons in the general U.S. population and trends in this difference over time. DESIGN Observational cohort study. SETTING Thirteen sites from the U.S. North American AIDS Cohort Collaboration on Research and Design. PARTICIPANTS 82 766 adults entering HIV clinical care between 1999 and 2017 and a subset of the U.S. population matched on calendar time, age, sex, race/ethnicity, and county using U.S. mortality and population data compiled by the National Center for Health Statistics. MEASUREMENTS Five-year all-cause mortality, estimated using the Kaplan-Meier estimator of the survival function. RESULTS Overall 5-year mortality among persons entering HIV care was 10.6%, and mortality among the matched U.S. population was 2.9%, for a difference of 7.7 (95% CI, 7.4 to 7.9) percentage points. This difference decreased over time, from 11.1 percentage points among those entering care between 1999 and 2004 to 2.7 percentage points among those entering care between 2011 and 2017. LIMITATION Matching on available covariates may have failed to account for differences in mortality that were due to sociodemographic factors rather than consequences of HIV infection and other modifiable factors. CONCLUSION Mortality among persons entering HIV care decreased dramatically between 1999 and 2017, although those entering care remained at modestly higher risk for death in the years after starting care than comparable persons in the general U.S. population.

Current and Past Immunodeficiency Are Associated With Higher Hospitalization Rates Among Persons on Virologically Suppressive Antiretroviral Therapy for up to 11 Years. J Infect Dis 2021; 224:657-666.

Abstract
BACKGROUND Persons with human immunodeficiency virus (PWH) with persistently low CD4 counts despite efficacious antiretroviral therapy could have higher hospitalization risk. METHODS In 6 US and Canadian clinical cohorts, PWH with virologic suppression for ≥1 year in 2005-2015 were followed until virologic failure, loss to follow-up, death, or study end. Stratified by early (years 2-5) and long-term (years 6-11) suppression and lowest presuppression CD4 count <200 and ≥200 cells/µL, Poisson regression models estimated hospitalization incidence rate ratios (aIRRs) comparing patients by time-updated CD4 count category, adjusted for cohort, age, gender, calendar year, suppression duration, and lowest presuppression CD4 count. RESULTS The 6997 included patients (19 980 person-years) were 81% cisgender men and 40% white. Among patients with lowest presuppression CD4 count <200 cells/μL (44%), patients with current CD4 count 200-350 vs >500 cells/μL had aIRRs of 1.44 during early suppression (95% confidence interval [CI], 1.01-2.06), and 1.67 (95% CI, 1.03-2.72) during long-term suppression. Among patients with lowest presuppression CD4 count ≥200 (56%), patients with current CD4 351-500 vs >500 cells/μL had an aIRR of 1.22 (95% CI, .93-1.60) during early suppression and 2.09 (95% CI, 1.18-3.70) during long-term suppression. CONCLUSIONS Virologically suppressed patients with lower CD4 counts experienced higher hospitalization rates and could potentially benefit from targeted clinical management strategies.

Abstract
BACKGROUND Evidence-based interventions are needed to address the use of stimulants such as methamphetamine as a driver of onward HIV transmission and faster clinical HIV progression among sexual minority men. Prior randomized controlled trials with people living with HIV who use substances indicate that financial incentives provided during contingency management (CM) are effective for achieving short-term reductions in stimulant use and HIV viral load. However, the benefits of CM are often not maintained after financial incentives for behavior change end. PURPOSE Data from a recently completed randomized controlled trial with 110 sexual minority men living with HIV who use methamphetamine was leveraged to examine mediators of the efficacy of a positive affect intervention for extending the benefits of CM. METHODS An autoregressive cross-lagged model was fit to determine if reductions in HIV viral load were mediated by intervention-related increases in positive affect and decreases in stimulant use measured in four waves over 15 months. RESULTS Higher baseline positive affect predicted significantly lower self-reported stimulant use immediately following the 3-month CM intervention period, even after controlling for self-reported stimulant use at baseline. Moreover, decreased stimulant use emerged as an independent predictor of long-term reductions HIV viral load at 15 months, even after adjusting for HIV viral load at baseline and the residual effect of the positive affect intervention. CONCLUSIONS Findings underscore the importance of durable reductions in stimulant use as a primary intervention target that is essential for optimizing the clinical and public health benefits of HIV treatment as prevention.

Estimating the effect of increasing dispensing intervals on retention in care for people with HIV in Haiti. EClinicalMedicine 2021; 38:101039.

Abstract
BACKGROUND Multi-month dispensing (MMD) for antiretroviral therapy (ART) is a promising care strategy to improve HIV treatment adherence. The effectiveness of MMD in routine settings has not yet been evaluated within a causal inference framework. We analyzed data from a robust clinical data system to evaluate MMD in Haiti. METHODS We assessed 1-year retention in care among 21,880 ART-naïve HIV-positive persons who started ART on or after January 1, 2017, up until November 1, 2018. We used an instrumental variable analysis to estimate the causal impact of MMD. This approach was used to address potential selection into specific dispensing intervals because MMD is not randomly applied to individuals. FINDINGS We found that extending ART dispensing intervals increased the probability of retention at 12 months after ART initiation, with up to a 24·2%-point increase (95%CI: 21·9, 26·5) in the likelihood of retention with extending dispenses by 30 days for those receiving one-month dispenses. We observed statistically significant gains to retention with MMD with up to an approximately 4-month supply of ART; +5·1%-points (95%CI: 2·4,7·8). Increasing dispensing lengths for those already receiving ≥5-month supply of ART had a potentially negative effect on retention. INTERPRETATION MMD for ART is an effective service delivery strategy that improves care retention for new ART recipients. There is a potentially negative effect of increasing prescription lengths for those new ART recipients already receiving longer ART supplies, though more research is needed to characterize this effect given medication supplies of this length are not common for newer ART recipients.

Possible mechanisms of HIV neuro-infection in alcohol use: Interplay of oxidative stress, inflammation, and energy interruption. Alcohol 2021; 94:25-41.

Abstract
Alcohol use and HIV-1 infection have a pervasive impact on brain function, which extends to the requirement, distribution, and utilization of energy within the central nervous system. This effect on neuroenergetics may explain, in part, the exacerbation of HIV-1 disease under the influence of alcohol, particularly the persistence of HIV-associated neurological complications. The objective of this review article is to highlight the possible mechanisms of HIV/AIDS progression in alcohol users from the perspective of oxidative stress, neuroinflammation, and interruption of energy metabolism. These include the hallmark of sustained immune cell activation and high metabolic energy demand by HIV-1-infected cells in the central nervous system, with at-risk alcohol use. Here, we discussed the point that the increase in energy supply requirement by HIV-1-infected neuroimmune cells as well as the deterrence of nutrient uptake across the blood-brain barrier significantly depletes the energy source and neuro-environment homeostasis in the CNS. We also described the mechanistic idea that comorbidity of HIV-1 infection and alcohol use can cause a metabolic shift and redistribution of energy usage toward HIV-1-infected neuroimmune cells, as shown in neuropathological evidence. Under such an imbalanced neuro-environment, meaningless energy waste is expected in infected cells, along with unnecessary malnutrition in non-infected neuronal cells, which is likely to accelerate HIV neuro-infection progression in alcohol use. Thus, it will be important to consider the factor of nutrients/energy imbalance in formulating treatment strategies to help impede the progression of HIV-1 disease and associated neurological disorders in alcohol use.

Abstract
OBJECTIVE To examine recent trends and differences in all-cause and cause-specific hospitalization rates by race, ethnicity, and gender among persons with HIV (PWH) in the United States and Canada. DESIGN HIV clinical cohort consortium. METHODS We followed PWH at least 18 years old in care 2005-2015 in six clinical cohorts. We used modified Clinical Classifications Software to categorize hospital discharge diagnoses. Incidence rate ratios (IRR) were estimated using Poisson regression with robust variances to compare racial and ethnic groups, stratified by gender, adjusted for cohort, calendar year, injection drug use history, and annually updated age, CD4+, and HIV viral load. RESULTS Among 27 085 patients (122 566 person-years), 80% were cisgender men, 1% transgender, 43% White, 33% Black, 17% Hispanic of any race, and 1% Indigenous. Unadjusted all-cause hospitalization rates were higher for Black [IRR 1.46, 95% confidence interval (CI) 1.32-1.61] and Indigenous (1.99, 1.44-2.74) versus White cisgender men, and for Indigenous versus White cisgender women (2.55, 1.68-3.89). Unadjusted AIDS-related hospitalization rates were also higher for Black, Hispanic, and Indigenous versus White cisgender men (all P < 0.05). Transgender patients had 1.50 times (1.05-2.14) and cisgender women 1.37 times (1.26-1.48) the unadjusted hospitalization rate of cisgender men. In adjusted analyses, among both cisgender men and women, Black patients had higher rates of cardiovascular and renal/genitourinary hospitalizations compared to Whites (all P < 0.05). CONCLUSION Black, Hispanic, Indigenous, women, and transgender PWH in the United States and Canada experienced substantially higher hospitalization rates than White patients and cisgender men, respectively. Disparities likely have several causes, including differences in virologic suppression and chronic conditions such as diabetes and renal disease.

Abstract
Psychosocial syndemic conditions have received more attention regarding their deleterious effects on HIV acquisition risk than for their potential impact on HIV treatment and viral suppression. To examine syndemic conditions' impact on the HIV care continuum, we analyzed data collected from people living with HIV (N = 14,261) receiving care through The Centers for AIDS Research Network of Integrated Clinical Systems at seven sites from 2007 to 2017 who provided patient-reported outcomes ∼4-6 months apart. Syndemic condition count (depression, anxiety, substance use, and hazardous drinking), sexual risk group, and time in care were modeled to predict antiretroviral therapy (ART) adherence and viral suppression (HIV RNA <400 copies/mL) using multilevel logistic regression. Comparing patients with each other, odds of ART adherence were 61.6% lower per between-patient syndemic condition [adjusted odds ratio (AOR) = 0.384; 95% confidence interval (CI), 0.362-0.408]; comparing patients with themselves, odds of ART adherence were 36.4% lower per within-patient syndemic condition (AOR = 0.636 95% CI, 0.606-0.667). Odds of viral suppression were 29.3% lower per between-patient syndemic condition (AOR = 0.707; 95% CI, 0.644-0.778) and 27.7% lower per within-patient syndemic condition (AOR = 0.723; 95% CI, 0.671-0.780). Controlling for the effects of adherence (AOR = 5.522; 95% CI, 4.67-6.53), each additional clinic visit was associated with 1.296 times higher odds of viral suppression (AOR = 1.296; 95% CI, 1.22-1.38), but syndemic conditions were not significant. Deploying effective interventions within clinics to identify and treat syndemic conditions and bolster ART adherence and continued engagement in care can help control the HIV epidemic, even within academic medical settings in the era of increasingly potent ART.

The longitudinal association between depression, anxiety symptoms and HIV outcomes, and the modifying effect of alcohol dependence among ART clients with hazardous alcohol use in Vietnam. J Int AIDS Soc 2021; 24 Suppl 2:e25746. [PMID: 34165258 PMCID: PMC8222856 DOI: 10.1002/jia2.25746] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Revised: 04/14/2021] [Accepted: 04/28/2021] [Indexed: 01/15/2023] Open
Abstract
INTRODUCTION Mental health disorders may negatively impact HIV outcomes, such as viral suppression (VS) and antiretroviral (ART) adherence among people with HIV (PWH) with hazardous alcohol use. This study evaluates the longitudinal association between depression, anxiety symptoms, VS and complete ART adherence among ART clients with hazardous alcohol use in Vietnam; and examines alcohol dependence as a modifier in this association. METHODS This was a secondary data analysis of a trial for hazardous drinking ART clients in Thai Nguyen, Vietnam. From March 2016 to May 2018, 440 ART clients with an Alcohol Use Disorders Identification Test-Concise (AUDIT-C) score ≥4 for men and ≥3 for women were enrolled. Individuals were randomized to either a combined intervention, a brief intervention or a standard of care. Data on sociodemographics, depression, anxiety symptoms, alcohol use, VS and ART adherence were collected at baseline, three, six, and twelve months. Generalized estimating equation models controlling for intervention exposure were used to estimate time-lagged associations. Risk ratios were estimated using Poisson regression with robust variance estimation. RESULTS The mean age of participants was 40.2. The majority was male (96.8%), had at least some secondary school education (85.0%) and had a history of injection drug use (80.9%). No overall effect of depression and anxiety symptoms on VS was observed. When stratified by time, increased anxiety symptoms at six months were associated with VS at 12 months (adjusted risk ratio (aRR) = 1.09; 95% CI 1.02 to 1.17). An increase in depression or anxiety symptoms was associated with a decreased probability of complete ART adherence (depression symptoms: aRR = 0.95; 95% CI: 0.91 to 0.99; anxiety symptoms: aRR = 0.93; 85% CI: 0.88 to 0.99). The negative effects of anxiety symptoms on ART adherence were stronger among participants with alcohol dependence, compared to those without. CONCLUSIONS Depression and anxiety symptoms had no overall effect on VS, although they were associated with a lower probability of complete ART adherence. Interventions focusing on mental healthcare for PWH with hazardous alcohol use are needed, and integration of mental healthcare and alcohol reduction should be implemented in HIV primary care settings.

Abstract
We examined HIV viral load non-suppression ([Formula: see text] 200 copies/mL) subsequent to person-periods (3-18 months) bookended by two self-reports of alcohol use on a standardized patient reported outcome assessment among adults in routine HIV care. We examined the relative risk (RR) of non-suppression associated with increases and decreases in alcohol use (relative to stable use), stratified by use at the start of the person-period. Increases in drinking from abstinence were associated with higher risk of viral non-suppression (low-risk without binge: RR 1.16, 95% CI 1.03, 1.32; low-risk with binge: RR 1.35, 95% CI 1.11, 1.63; high-risk: RR 1.89, 95% CI 1.16, 3.08). Decreases in drinking from high-risk drinking were weakly, and not statistically significantly associated with lower risk of viral non-suppression. Other changes in alcohol use were not associated with viral load non-suppression. Most changes in alcohol consumption among people using alcohol at baseline were not strongly associated with viral non-suppression.

Abstract
Integrase inhibitor–based (INSTI) antiretroviral therapy (ART) regimens are preferred for most people with HIV (PWH). We examined factors associated with INSTI use among PWH in San Francisco who started ART in 2009–2016. PWH who experienced homelessness were less likely, and older PWH were more likely, to use an INSTI.

Abstract
Adherence to antiretroviral therapy (ART) enables people living with HIV (PLWH) to reach and maintain viral suppression. As viral suppression significantly reduces risk for secondary transmission, this study aimed to examine sociodemographic factors associated with viral suppression among PLWH in South Carolina (SC). We analyzed cross-sectional data collected from 342 PLWH receiving HIV care from a large clinic in SC and provided complete information on most recent viral load, ART adherence, and sociodemographic factors. Bivariate analysis examined associations between key variables, and logistic regression was used to calculate the odds of viral suppression among select sociodemographic groups and adherence levels. Results indicated that approximately 82% of participants reported achieving viral suppression. PLWH who were older, male, and employed full-time had higher odds of being virally suppressed compared to those who were younger, female, and unemployed. PLWH with medium (adjusted Odds Ratio [aOR]: 3.79; 95% CI: 1.15-12.48) and high (aOR: 3.51; 95% CI: 1.21-10.24) levels of adherence were more likely to report viral suppression than those with low adherence. Targeted interventions are warranted for groups at-risk of low ART adherence, and healthcare providers should also be aware of contextual factors that serve as barriers to adherence for PLWH.

Estimating HIV transmissions in a large U.S. clinic-based sample: effects of time and syndemic conditions. J Int AIDS Soc 2021; 24:e25679.

Abstract
INTRODUCTION Little is known about onward HIV transmissions from people living with HIV (PLWH) in care. Antiretroviral therapy (ART) has increased in potency, and treatment as prevention (TasP) is an important component of ending the epidemic. Syndemic theory has informed modelling of HIV risk but has yet to inform modelling of HIV transmissions. METHODS Data were from 61,198 primary HIV care visits for 14,261 PLWH receiving care through the Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS) at seven United States (U.S.) sites from 2007 to 2017. Patient-reported outcomes and measures (PROs) of syndemic conditions - depressive symptoms, anxiety symptoms, drug use (opiates, amphetamines, crack/cocaine) and alcohol use - were collected approximately four to six months apart along with sexual behaviours (mean = 4.3 observations). Counts of syndemic conditions, HIV sexual risk group and time in care were modelled to predict estimated HIV transmissions resulting from sexual behaviour and viral suppression status (HIV RNA < 400/mL) using hierarchical linear modelling. RESULTS Patients averaged 0.38 estimated HIV transmissions/100 patients/year for all visits with syndemic conditions measured (down from 0.83, first visit). The final multivariate model showed that per 100 patients, each care visit predicted 0.05 fewer estimated transmissions annually (95% confidence interval (CI): 0.03 to 0.06; p < 0.0005). Cisgender women, cisgender heterosexual men and cisgender men of undisclosed sexual orientation had, respectively, 0.47 (95% CI: 0.35 to 0.59; p < 0.0005), 0.34 (95% CI: 0.20 to 0.49; p < 0.0005) and 0.22 (95% CI: 0.09 to 0.35; p < 0.005) fewer estimated HIV transmissions/100 patients/year than cisgender men who have sex with men (MSM). Each within-patient syndemic condition predicted 0.18 estimated transmissions/100 patients/year (95% CI: 0.12 to 0.24; p < 0.0005). Each between-syndemic condition predicted 0.23 estimated HIV transmissions/100 patients/year (95% CI: 0.17 to 0.28; p < 0.0005). CONCLUSIONS Estimated HIV transmissions among PLWH receiving care in well-resourced U.S. clinical settings varied by HIV sexual risk group and decreased with time in care, highlighting the importance of TasP efforts. Syndemic conditions remained a significant predictor of estimated HIV transmissions notwithstanding the effects of HIV sexual risk group and time in care.

Abstract
OBJECTIVES Evaluate differences in weight change by regimen among people living with HIV (PLWH) initiating antiretroviral therapy (ART) in the current era. METHODS Between 2012 and 2019, 3232 ART-naïve PLWH initiated ≥3-drug ART regimens in 8 Centers for AIDS Research Network of Integrated Clinical Systems sites. We estimated weight change by regimen for 11 regimens in the immediate (first 6 months) and extended (all follow-up on initial regimen) periods using linear mixed models adjusted for time on regimen, interaction between time and regimen, age, sex, race/ethnicity, hepatitis B/C coinfection, nadir CD4, smoking, diabetes, antipsychotic medication, and site. We included more recently approved regimens [eg, with tenofovir alafenamide fumarate (TAF)] only in the immediate period analyses to ensure comparable follow-up time. RESULTS Mean follow-up was 1.9 years on initial ART regimen. In comparison to efavirenz/tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC), initiating bictegravir/TAF/FTC {3.9 kg [95% confidence interval (CI): 2.2 to 5.5]} and dolutegravir/TAF/FTC [4.4 kg (95% CI: 2.1 to 6.6)] were associated with the greatest weight gain in the immediate period, followed by darunavir/TDF/FTC [3.7 kg (95% CI: 2.1 to 5.2)] and dolutegravir/TDF/FTC [2.6 kg (95% CI: 1.3 to 3.9)]. In the extended period, compared with efavirenz/TDF/FTC, initiating darunavir/TDF/FTC was associated with a 1.0 kg (95% CI: 0.5 to 1.5) per 6-months greater weight gain, whereas dolutegravir/abacavir/FTC was associated with a 0.6-kg (95% CI: 0.3 to 0.9) and dolutegravir/TDF/FTC was associated with a 0.6-kg (95% CI: 0.1 to 1.1) per 6-months greater gain. Weight gain on dolutegravir/abacavir/FTC and darunavir/TDF/FTC was significantly greater than that for several integrase inhibitor-based regimens. CONCLUSIONS There is heterogeneity between regimens in weight gain following ART initiation among previously ART-naïve PLWH; we observed greater gain among PLWH taking newer integrase strand transfer inhibitors (DTG, BIC) and DRV-based regimens.

Has depression surpassed HIV as a burden to gay and bisexual men's health in the United States? A comparative modeling study. Soc Psychiatry Psychiatr Epidemiol 2021; 56:273-282. [PMID: 32785755 PMCID: PMC7870461 DOI: 10.1007/s00127-020-01938-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2020] [Accepted: 08/07/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND While advances in HIV prevention and treatment have changed the epidemic for gay and bisexual men, another epidemic faces this population. Gay and bisexual men represent one of the highest risk groups for depression, which potentially poses quality-of-life and public health challenges comparable to those of HIV. The present study seeks to inform comprehensive care for sexual minority men by estimating and comparing the morbidity of HIV and depression for US gay and bisexual men. METHODS In 2018, weighted counts of gay and bisexual men living with HIV and depression were derived from the CDC's Medical Monitoring Project and the National Survey on Drug Use and Health, respectively. Years lived with disability for HIV and depression were calculated using the Global Burden of Disease Study's disability weights. FINDINGS Among gay and bisexual adult men in the US, the prevalence of past-year major depressive episodes is 14.17%, while the prevalence of HIV is 11.52%. We estimate that in calendar year 2015, major depressive episodes imposed 85,361 (95% CI 58,293-112,212) years lived with disability among US adult gay and bisexual men, whereas HIV posed 42,981 (95% CI 36,221-49,722) years lived with disability. INTERPRETATION This analysis shows that depression morbidity currently exceeds that for HIV among US adult gay and bisexual men. While gay and bisexual men are frequently understood to be a high-risk population for HIV, including in guidelines for HIV prevention and treatment, the present analysis suggests that this population should also be considered high-risk for depression.
