P-1050. A Decade of Pneumocystis jirovecii Pneumonia: a Single-Center Retrospective Analysis in Both HIV and Non-HIV Populations

Abstract Background Pneumocystis jirovecii pneumonia (PJP) is a life-threatening opportunistic disease, commonly occurring in individuals with human immunodeficiency virus (HIV) or immunodepression. This study analyzes PJP cases in our local setting, detailing the epidemiological and clinical characteristics, as well as prognosis, and underlying diseases. Methods Retrospective analysis of adult inpatient PJP cases (2014-2023). Diagnosis was presumptive (epidemiological, clinical, and imaging findings), or confirmed microbiologically. Statistical analysis utilized the chi-square test. Results Forty-two patients were identified: 66% male, median age of 47.5 years [25-83]. Seventy-four percent were HIV positive, with a median CD4+ count of 35 [1-347]. All had detectable HIV viral load, except one (suppressed for years, but with a new diagnosis of neoplasm). Non-HIV patients (26%) underlying diseases included hematological (n=6) or solid-organ malignancies (n=1), autoimmune diseases under corticosteroid therapy (n=2), pulmonary interstitial disease (n=1), and granulomatous systemic disease under investigation (n=1). Eighty-six percent had peripheral lymphopenia at diagnosis, and only one patient was receiving regular prophylaxis. The incidence of non-HIV patients significantly increased in the latter 5 years (5.5% vs 42%, p=0.008). Diagnosis was confirmed by positive direct antibody fluorescence staining in half of the patients. No molecular biology techniques or B-D-glucan assays were available. Seventeen (40%) patients required admission to level II or III units, of which 23% required invasive mechanical ventilation and 35% high-flow oxygen. Treatment included cotrimoxazole (n=40) and atovaquone (n=2). One-third of patients had cytomegalovirus reactivation, requiring antiviral therapy. Non-HIV patient mortality was significantly higher than HIV patients (45% vs 13%, p=0.023). Fifteen percent of survivors were readmitted within 30 days. Conclusion The epidemiology of PJP is evolving, with a noticeable increase in non-HIV cases, which are associated with significantly higher mortality despite appropriate treatment. Authors emphasize the importance of identifying new risk groups for chemoprophylaxis to improve prognosis. Disclosures All Authors: No reported disclosures

P-458. Factors Associated with Completion of High-Resolution Anoscopy in a Cohort of Transgender Women – Findings from a Mixed-Methods Study

Abstract Background Guidelines recommend anal cancer screening in transgender women (TGW) – particularly those living with HIV (LWH) - using anal cytology followed by high-resolution anoscopy (HRA) in those with abnormal results. This study examines factors associated with completion of HRA in TGW with abnormal cytology. Methods We recruited 80 TGW using convenience sampling from 4/2021 – 9/2023. We collected survey data, serum samples, and anal swabs for cytology and HPV testing. TGW with abnormal cytology were scheduled for off-site HRA. Non-completion of HRA was defined as being scheduled for HRA but not completing it within 3 months of cytology result. We conducted semi-structured interviews with 8 TGW who completed HRA and 8 who didn’t complete HRA. We used chi-square tests and the weaved approach to compare factors associated with HRA completion from quantitative and qualitative data. Results Of 75 TGW with anal cytology collected, 48% had abnormal results and of those 39% completed HRA (Figure 1). Of 36 TGW with abnormal cytology 97% were black, 61% were unstably housed, 78% were LWH. In the last year, 48% engaged in transactional sex and 69% in receptive anal sex (Table 1). HRA completion was associated with being employed (p=0.01) and, among TGW LWH, an undetectable HIV viral load (p=0.01) (Table 1). Qualitative data identified patient-provider trust as a facilitator to HRA completion and experiences of stigma or discrimination related to gender identity as a barrier to HRA completion (Table 2). Mixed-methods analysis revealed that socio-economic challenges, including housing, and financial factors – notably health insurance - were a barrier to HRA completion (Table 3). Conclusion In a cohort of TGW, we found high rates of abnormal anal cytology and low rates of HRA completion, highlighting missed opportunities for anal cancer prevention. Interventions aimed at improving anal cancer screening and linkage to HRA for TGW must be intentional about eschewing stigma and creating environments affirming of gender identity, while addressing barriers to care due to prevalent socioeconomic challenges. Additionally, TGW LWH with a detectable HIV viral load may require further targeted interventions to improve both the HIV care continuum and the anal cancer screening cascade.

Cervical dysplasia in women with HIV in the modern treat-all era: Elevated risk remains despite long-term ART and normal CD4 count.

To evaluate the impact of ART duration and CD4 count on risk for high grade cervical dysplasia in women with HIV (WWH) compared to women without HIV in the treat-all era with integrase strand inhibitors (INSTIs). Prospective longitudinal cohort study in Botswana. From February 2021 to August 2022, baseline HPV self-sampling was offered to women with and without HIV. Those HPV+ underwent biopsy for histopathological diagnosis. Using women without HIV as reference, risk ratios (RRs) were calculated for HPV, cervical intraepithelial neoplasia (CIN) 2 or worse (CIN2+), and CIN3+, stratified by ART duration and CD4 cell counts. Of 3000 women enrolled, 2953(98.4%) underwent HPV testing, which was positive in 823(55.7%) WWH and in 654(44.3%) women without HIV. Histopathology was available for analysis in 1291(87.4%) women (709 WWH, 582 women without HIV). Over 99% of WWH had detectable HIV viral load and 94.4% were on a dolutegravir-based ART regimen. WWH had a higher risk of HPV (RR1.27,95%CI:1.18,1.37), CIN2+ (RR1.52,95%CI:1.16,1.98) and CIN3+ (RR1.75,95%CI:1.25,2.45) compared to women without HIV. There was attenuation of risk for CIN2+ with higher recent CD4 cell count, and those with higher nadir CD4 count had similar risk to those without HIV (nadir CD4≥500 CIN2+ RR1.15[95%CI:0.56,2.37], CIN3+ RR1.81[95% CI:0.86,3.79]; nadir CD4 350-499 CIN2+ RR1.23[95% CI:0.71,2.12], CIN3+ RR1.34[95%CI:0.68,2.64]). Although some attenuation of risk for CIN2+ was observed with higher recent and nadir CD4 cell counts, WWH continue to have a higher risk of CIN2+/CIN3+ compared to women without HIV. These findings support tailored cervical screening algorithms for WWH.

Employment Status and HIV Viral Load in Chilean Adult Population: A Propensity Score Analysis.

We set out to investigate the potential impact of unemployment on HIV viral load in individuals living with HIV at the biggest HIV-related healthcare centre in Chile. We analysed a cross-sectional dataset of 803 adults living with HIV on antiretroviral therapy. The main exposure was employment status. The outcome, detectable HIV viral load, was operationalised using a cut-off of HIV viral load at 20 copies/mL. We applied a propensity score method, the inverse probability of treatment weighting to control for measured confounders. We found that 219 (27.3%) of participants were unemployed. Being unemployed was associated with increased odds of being detectable (OR = 1.78, 95%CI = 1.18-2.71) compared to being employed. Additionally, we found that those unemployed and non-adherents have higher odds of being detectable (OR = 2.53, 95%CI = 1.18-5.41). Unemployment status may influence HIV viral load. However, further research is needed to determine and understand the social structure behind those relationships in the Chilean people living with HIV.

Anal Cancer Screening: 10-Year Experience of a Specialized Outpatient Clinic.

In 2012, the Department of Visceral Surgery of the Lausanne University Hospital CHUV implemented a dedicated high-resolution anoscopy (HRA) outpatient clinic for surveillance and follow-up purposes. This 10-year longitudinal study analyzed 537 patients (2214 visits) using a structured screening protocol. Dysplastic lesions were detected in 49% of patients, predominantly low-grade squamous intraepithelial lesions (LSILs, 74%). Among LSIL cases, 6% progressed to high-grade squamous intraepithelial lesions (HSILs) within 24 months, reaching 25% cumulative progression at 36 months. Of HSIL patients, 3% developed carcinoma in situ after 48 months. Notably, no invasive carcinoma was observed during the follow-up. Four patients diagnosed with squamous cell carcinoma at initial screening were treated with chemoradiotherapy, and one required salvage surgery. Independent risk factors for the presence of higher-stage precancerous lesions (≥HSILs) were the presence of high-risk HPV genotypes (OR 14.5, 95% CI 5-42.2, p < 0.001), detectable HIV viral load (OR 5.4, 95% CI 1.8-16.7, p = 0.003), and symptoms at the first screening visit (OR 3.2, 95% CI 1.1-9.9, p = 0.04). HIV-positive status was associated with a trend towards an increased risk of progression (OR 2.79, p = 0.073). These findings highlight the importance of systematic follow-up and early intervention in high-risk populations to prevent anal cancer progression.

Assessment of the relationship between Epstein–Barr virus major types and genovariants as well as clinical and laboratory parameters in HIV-infected adults

Introduction. People living with human immunodeficiency virus (HIV) are more likely to experience Epstein–Barr virus (EBV) reactivation and develop EBV-associated diseases. In Russia, the clinical significance of EBV genetic diversity in HIV-infected patients has not been assessed. The aim was to analyze a relationship between the major EBV types and LMP-1 genovariants with clinical and laboratory parameters in HIV-infected persons. Materials and methods. Peripheral blood leukocytes were collected from 138 HIV(+) individuals aged 20–69 years. Association between EBV types, LMP-1 variants and subvariants with clinical and laboratory parameters (CD4+ T-lymphocyte count, HIV and EBV viral load, use and adherence to antiretroviral therapy (ART)), was performed using the principal component analysis method and the Mann–Whitney U test. Results. It has been shown that detectable HIV viral load increases in patients with low CD4+ T-lymphocyte counts, high EBV viral load, and low or no ART adherence. In general, infection with EBV-2 or the LMP-1 B95-8 alone resulted in lower EBV and HIV viral loads compared with other variants. Significant EBV-1 LMP-1 subvariants were identified, the biological potential of which was enabled in immunodeficiency state (CD4+ T-lymphocyte count ≤ 200 cells/μl). In “naive” patients, EBV-1/LMP-1 (S309N)+HIV co-infection occurred with a higher, and EBV-1/LMP-1(E328Q)+HIV with the lowest HIV viral load. The highest EBV DNA concentrations were observed with EBV-1/LMP-1(Q334R)+HIV. In “experienced” patients, the level of EBV DNA was significantly lower when infected with EBV-1/LMP-1(E328Q)+HIV and, conversely, higher in case of detected EBV-1/LMP-1(H358P)+HIV. Conclusion. The features of clinical and laboratory parameters EBV+HIV co-infection caused by different EBV-1 LMP-1 subvariants (at the level of amino acid substitutions S309N, E328Q, Q334R, H358P) have been identified. It is necessary to study the functional role of such mutations in vitro and in vivo. In the context of assessing a clinical significance of EBV molecular genetic diversity, it is advisable to conduct larger-scale studies in different territories of Russia.

Comorbidities associated with chronic kidney disease among young people living with HIV in Uganda. A nested case control study.

Chronic kidney disease (CKD) is often complicated by disorders in multiple body systems, associated with higher mortality and morbidity. Young people living with HIV (YPLHIV) have an increased risk of multisystem chronic comorbidities. However, there are few data describing comorbidities associated with CKD among YPLHIV. We conducted a case-control study in seven ART clinics in Kampala, Uganda. Cases were YPLHIV (aged 10-24 years) diagnosed with CKD and controls were those without CKD. We collected data on demographic and clinical factors: blood pressure, fasting glucose levels, anaemia, electrolytes, parathyroid hormone, and cognitive impairment. We summarized the demographic and clinical factors and used logistic regression to estimate odds ratios (OR) and 95% confidence intervals for associations between CKD comorbidities, adjusted for age, sex and viral suppression. A total of 292 participants (96 cases and 196 controls) were recruited. Cases were mostly male (59.4% vs 36.5%), and younger (88.5% vs 46.4% aged <17 years) compared to controls. CKD was associated with having a detectable HIV viral load (OR=3.73; 95% CI 1.53-9.12) and proteinuria (aOR=4.19; 95% CI 2.28-7.72). CKD was also associated with low haematocrit, hypochloraemia, hyperphosphatemia, and high mean corpuscular volume. There was no evidence of an association of CKD with hypertension, anaemia, or stunting. The pattern of comorbidities among YPLHIV with CKD is uncertain and difficulties may relate to difficulty determining true kidney function and normal ranges in this population. Further studies are needed to discern the pattern of CKD complications to improve management efforts and clinical outcomes.

Mpox in People With Human Immunodeficiency Virus: Predictors of Diagnosis, Outcomes, and Vaccine Effectiveness in a Multisite Cohort.

Since its global reemergence in 2022, monkeypox (mpox) has demonstrated increased incidence and severity among people with human immunodeficiency virus (HIV [PWH]). Predictors of mpox diagnosis, vaccination, and outcomes among PWH are limited. We included PWH with primary care visits after 1 January 2022 at 9 US sites participating in the Centers for AIDS Research Network of Integrated Clinic Systems Network. We identified mpox diagnosed between 1 June 2022 and 31 May 2023, through a combination of polymerase chain reaction result, diagnosis code, and/or tecovirimat receipt. We examined validated clinical diagnoses, laboratory results, vaccine data, and patient reported outcomes. We evaluated relative risks (RR) of mpox diagnosis, hospitalization, tecovirimat treatment, and vaccine receipt. Among 19 777 PWH in care, 413 mpox cases (all male sex at birth) occurred (2.2 cases/100 person-years). Age <40 years, geographic region, Hispanic/Latine ethnicity, lack of antiretroviral therapy, detectable HIV viral load, and recent bacterial sexually transmitted infection predicted mpox diagnosis. PWH with CD4 200-349 cells/mm3 were most likely to be hospitalized (adjusted RR, 3.20; 95% confidence interval: 1.44-7.09) compared to CD4 ≥500, but half as likely as those with CD4 <200 to receive tecovirimat. Overall, smallpox/mpox vaccine effectiveness of ≥1 vaccine was 71% (adjusted RR, 0.29; 95% confidence interval: .14-.47) at preventing mpox, and 86% or better with CD4 ≥350 or HIV viral suppression. Non-Hispanic Black PWH were less likely to be vaccinated than other racial/ethnic identities. PWH not on antiretroviral therapy or with unsuppressed HIV were more likely to be diagnosed with, and hospitalized for, mpox. Mpox/smallpox vaccine effectiveness was high, inclusive of those with low CD4 count and HIV viremia.

Supporting treatment adherence for resilience and thriving (START): protocol for a mHealth randomized controlled trial

BackgroundAlthough behavioral interventions show some promise for reducing stimulant use and achieving durable viral suppression in sexual minority men (SMM) with HIV, scalable mHealth applications are needed to optimize their reach and cost-effectiveness.MethodsSupporting Treatment Adherence for Resilience and Thriving (START) is a randomized controlled trial (RCT) testing the efficacy and cost-effectiveness of a mHealth application that integrates evidence-based positive affect regulation skills with self-monitoring of adherence and mood. The primary outcome is detectable HIV viral load (i.e., > 300 copies/mL) from self-collected dried blood spot (DBS) specimens at 6 months. Secondary outcomes include detectable DBS viral load at 12 months, self-reported stimulant use severity, anti-retroviral therapy (ART) adherence, and positive affect over 12 months. A national sample of up to 250 SMM with HIV who screen positive for stimulant use disorder and reporting suboptimal ART adherence is being recruited via social networking applications through April of 2024. After providing informed consent, participants complete a run-in period (i.e., waiting period) including two baseline assessments with self-report measures and a self-collected DBS sample. Those who complete the run-in period are randomized to either the START mHealth application or access to a website with referrals to HIV care and substance use disorder treatment resources. Participants provide DBS samples at baseline, 6, and 12 months to measure HIV viral load as well as complete self-report measures for secondary outcomes at quarterly follow-up assessments over 12 months.DiscussionTo date, we have paid $117,500 to advertise START on social networking applications and reached 1,970 eligible participants ($59.77 per eligible participant). Although we identified this large national sample of potentially eligible SMM with HIV who screen positive for a stimulant use disorder and report suboptimal ART adherence, only one-in-four have enrolled in the RCT. The run-in period has proven to be crucial for maintaining scientific rigor and reproducibility of this RCT, such that only half of consented participants complete the required study enrollment activities and attended a randomization visit. Taken together, findings will guide adequate resource allocation to achieve randomization targets in future mHealth research SMM with HIV who use stimulants.Trial RegistrationThis protocol was registered on clinicaltrials.gov (NCT05140876) on December 2, 2021.

People living with HIV with the Omicron variant infection have milder COVID-19 symptoms: results from a cross-sectional study

BackgroundChina braces for coronavirus disease 2019 (COVID-19) surge after adjusting the “zero COVID” strategy. We aimed to evaluate and compare the prevalence of clinical symptoms of the Omicron variant infection among people living with HIV (PLWH) and HIV-free people.MethodsA cross-sectional study was conducted in Wuchang District, Wuhan, Hubei Province, in December 2022 by a self-administered online survey during the Omicron wave. Participants aged ≥ 18 years with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnosis were recruited. PLWH managed by the local healthcare system were recruited, while HIV-free people were recruited by sending out online surveys through WeChat. We compared the prevalence of clinical symptoms of COVID-19 between PLWH and HIV-free people, and factors associated with symptom occurrence among PLWH were accessed.ResultsTotal, 687 PLWH and 1222 HIV-free people were enrolled. After adjusting sex, age, body mass index, comorbidities and COVID-19 vaccination status, the prevalences of all symptoms, including higher degree and long duration of fever (aOR 0.51, 95%CI 0·42 − 0·61; aOR 0.52, 95%CI 0·43 − 0·63), were significantly lower among PLWH than among HIV-free people. Among PLWH, CD4+ T lymphocyte count (CD4 count) between 350 ~ 499 cells/µL and detectable HIV viral load (HIV-VL) were associated with significantly decreased risks of fever (aOR 0·63, 95%CI 0·40 − 0·97; aOR 0·56, 95%CI 0·33 − 0·94), headache (aOR 0·61, 95%CI 0·41 − 0·91; aOR 0·55, 95%CI 0·34 − 0·92) and muscle soreness (aOR 0·57, 95%CI 0·39 − 0·84; aOR 0·57, 95%CI 0·39 − 0·84). No apparent association between the symptoms prevalence and three/four doses of inactivated COVID-19 vaccination among PLWH was observed; both males and older age were associated with significantly decreased risks of nasal congestion/runny nose (aOR 0·52, 95%CI 0·32 − 0·82; aOR 0·97, 95%CI 0·96 − 0·99) and headache (aOR 0·58, 95%CI 0·36 − 0·92; aOR 0·96, 95%CI 0·95 − 0·98); older age was associated with significantly decreased risks of higher degree of fever (aOR 0·97, 95%CI 0·95 − 0·98).ConclusionsPLWH have significantly milder symptoms of the Omicron variant infection than HIV-free people. PLWH who are male, older, have low CD4 count, and detectable HIV-VL have reduced occurrence of COVID-19 symptoms. However, continuous monitoring should be conducted among PLWH during the COVID-19 pandemic.

Metabolic dysfunction-associated steatohepatitis exhibits sex differences in people with HIV.

People with HIV are at increased risk for metabolic dysfunction-associated steatohepatitis (MASH). Although sex differences are documented in the general population, their role in the context of HIV is less understood. This was a multicentre cohort study including people with HIV without viral hepatitis coinfection. A FibroScan-AST (FAST) score >0.35 was used to diagnose MASH with significant liver fibrosis (stage F2-F4). We investigated sex-based differences in MASH trends as a function of age using a segmented linear mixed-effects model. Random effects accounted for clustering by the four sites. Adjusted models included ethnicity, diabetes, hypertension, and detectable HIV viral load. We included 1472 people with HIV (25% women). At baseline, the prevalence of MASH with fibrosis by FAST score was lower in women than in men (4.8% vs. 9.2%, p = 0.008). Based on the adjusted model, male sex (+0.034; p = 0.04), age per year (+0.003; p = 0.05), detectable HIV viral load (+0.034; p = 0.02), and hypertension (+0.03; p = 0.01) were positively associated with MASH with fibrosis. Although men exhibited generally higher FAST scores, FAST scores increased in women during the critical biological age of presumed perimenopause to menopause (between 40 and 50 years), reaching levels similar to those in men by the age of 55 years. Despite women with HIV having a lower prevalence of MASH with fibrosis than men, they exhibit an acceleration in FAST score increase around the perimenopausal age. Future studies should target adequate consideration of sex differences in clinical investigation of metabolic dysfunction-associated steatotic liver disease to fill current gaps and implement precision medicine for people with HIV.

Opioid Overdose Patients in Central Missouri, United States, Have High Rates of Hepatitis C Infection and Limited Testing History.

Cases of newly identified hepatitis C virus (HCV) infection increased 3.8-fold between 2010 and 2017 due to increasing injection drug use. Furthermore, multiple HIV outbreaks have been attributed to injection drug use. This retrospective cohort study assessed the prevalence of and testing history for HIV and HCV among opioid overdose patients in the emergency department. Each encounter including an opioid overdose at three emergency departments between January 2021 and May 2022 was reviewed. Emergency department note, most recent primary care note, and laboratory results from January 2000 to May 2022 were reviewed for the history of HIV and HCV testing. Fisher's exact test was used to identify associations of HIV and HCV status with age or gender. There were 134 encounters for 120 patients. A total of 72 were male and 48 were female. A total of 48 had a history of HCV testing. A total of 54 had a history of HIV testing. A total of 20 tested positive for HCV antibodies. One tested positive for HIV. Eight had detectable HCV viral loads, six had undetectable HCV viral loads, and six had no quantitative testing. One had a detectable HIV viral load. A total of 16.7% of both males and females had a history of a positive HCV test. Females were more likely to have ever received an HCV test compared to males (p=0.013, odds ratio (OR)=.68 (confidence interval (CI): 1.293-5.836)). Patients aged 55-64 were more likely to test positive than any other age group (p=0.018, OR=3.889 (CI: 1.391-11.81)), and were the least likely to be untested (p=0.037, OR=0.1905 (CI: 0.03914-0.9334)). There is a substantial burden of HCV among opioid overdose patients in central Missouri, United States, emergency departments, particularly among male patients and those aged 55-64. Universal HCV screening for individuals being observed following an overdose could detect many undiagnosed HCV infections.

HIV-infected Latin American asylum seekers in Madrid, Spain, 2022: A prospective cohort study from a major gateway in Europe.

BackgroundRecent migration trends have shown a notable entry of Latin American asylum seekers to Madrid, Spain.AimTo characterise the profile of asylum-seeking Latin American migrants who are living with HIV in Spain and to outline the barriers they face in accessing HIV treatment.MethodsA prospective cohort study was conducted between 2022 and 2023 with a 6-month follow-up period. Latin American asylum seekers living with HIV were recruited mainly from non-governmental organisations and received care at an HIV clinic in a public hospital in Madrid.ResultsWe included 631 asylum seekers. The primary countries of origin were Colombia (30%), Venezuela (30%) and Peru (18%). The median age was 32 years (interquartile range (IQR): 28-37), and 553 (88%) were cis men of which 94% were men who have sex with men. Upon their arrival, 49% (n = 309) lacked social support, and 74% (n = 464) faced barriers when attempting to access the healthcare system. Upon entry in Europe, 500 (77%) participants were taking antiretroviral therapy (ART). At their first evaluation at the HIV clinic, only 386 (61%) had continued taking ART and 33% (n = 209) had detectable plasma HIV-1 RNA levels. Six months later, 99% took ART and 98% had achieved an undetectable viral load.ConclusionsLatin American asylum seekers living with HIV in Madrid, Spain encountered barriers to healthcare and to ART. One-third of these individuals presented detectable HIV viral load when assessed in the HIV clinic, highlighting this as an important public health issue.

Perceived health-related quality of life in people living with HIV co-infected with SARS-CoV-2 in France

PurposeWe aimed to assess health-related quality of life (HRQL) and its correlates among people living with HIV/AIDS (PLWHA) co-infected with SARS-CoV-2 in France.MethodsThis cross-sectional was study conducted among PLWHA co-infected with SARS-CoV-2. HRQL was measured using the four dimensions of the PROQOL-HIV scale. Factors associated with each dimension were identified using linear regression.Resultsmean (SD) scores for HRQL dimensions: 76.7 (± 21.1) for Physical Health and Symptoms (PHS), 79.2 (± 23.6) for Social Relationships (SR), 67.3 (± 27.4) for Mental and Cognitive (MC), and 83.9 (± 16.5) for Treatment Impact (TI). Employment status and COVID-19 knowledge were associated with higher PHS score, while blood transfusion-acquired HIV, CDC HIV, hospital discharge instructions, and self-reported symptoms were associated with lower PHS score. Couple status was associated with higher SR score, whereas, hospital discharge instructions, CDC HIV stage C, drug injection-acquired HIV, self-reported symptoms, and COVID-19 vulnerability perception were associated with lower SR score. Employment status and French birth were associated with higher MC score, while female sex, detectable HIV viral load, hospital discharge instructions, COVID-19 vulnerability perception, smoking, and self-reported symptoms were associated with lower MC score. French birth and homosexual/bisexual relationships-acquired HIV were associated with higher TI score, while detectable HIV viral load, psychiatric disorders, and self-reported symptoms were associated with lower TI scoreConclusionAmong PLWHA co-infected with SARS-CoV-2, the scores of HRQL were impaired, particularly in the MC dimension. Findings underscore the multidimensional nature of HRQL, with notable variations across different dimensions. Understanding these correlates is crucial for tailored interventions aimed at improving the well-being of this population.

Association of comprehensiveness of antiretroviral care and detectable HIV viral load suppression among pregnant and postpartum women in the Democratic Republic of the Congo: a cross-sectional study.

Worldwide, over two-thirds of people living with HIV are on antiretroviral therapy (ART). Despite increased ART access, high virological suppression prevalence remains out of reach. Few studies consider the quality of ART services and their impact on recipients' viral suppression. We assessed the association between ART service readiness and HIV viral load suppression among pregnant and breastfeeding women living with HIV (WLH) receiving ART in maternal and child health (MCH) clinics in Kinshasa, Democratic Republic of Congo. We performed a cross-sectional analysis leveraging data from a continuous quality improvement intervention on WLH's long-term ART outcomes. From November 2016 to May 2020, we enrolled WLH from the three largest clinics in each of Kinshasa'Łs 35 health zones. We measured clinic's readiness using three WHO-identified ART care quality indicators: relevant guidelines in ART service area, stocks of essential ART medicines, and relevant staff training in ≥24 months, scoring clinics 0-3 based on observed indicators. We defined viral load suppression as ≤1,000 cp/ml. Multilevel mixed-effect logistic models were used to estimate prevalence odds ratios (ORs) measuring the strength of the association between ART service readiness and viral suppression. Of 2,295 WLH, only 1.9% received care from a clinic with a score of 3, 24.1% received care from a 0-scoring clinic, and overall, 66.5% achieved virologically suppression. Suppression increased from 65% among WLH receiving care in 0-scoring clinics to 66.9% in 1-scoring clinics, 65.8% in 2-scoring clinics, and 76.1% in 3-scoring clinics. We did not observe a statistically significant association between ART service readiness score and increased viral suppression prevalence, however we did find associations between other factors, such as the location of the health center and pharmacist availability with suppressed viral load. A lack of comprehensive ART care underscores the need for enhanced structural and organizational support to improve virological suppression and overall health outcomes for women living with HIV..

Geospatial and temporal mapping of detectable HIV-1 viral loads amid dolutegravir rollout in KwaZulu-Natal, South Africa.

South Africa rolled out dolutegravir (DTG) as first-line antiretroviral therapy (ART) in December 2019 to overcome high rates of pretreatment non-nucleoside reverse transcriptase inhibitor drug resistance. In the context of transition to DTG-based ART, this study spatiotemporally analysed detectable HIV viral loads (VLs) prior to- and following DTG rollout in public-sector healthcare facilities in KwaZulu-Natal (KZN) province, the epicentre of the HIV epidemic in South Africa. We retrospectively curated a HIV VL database using de-identified routine VL data obtained from the National Health Laboratory Service for the period January 2018 to June 2022. We analysed trends in HIV viraemia and mapped median log10 HIV VLs per facility on inverse distance weighted interpolation maps. We used Getis-Ord Gi* hotspot analysis to identify geospatial HIV hotspots. We obtained 7,639,978 HIV VL records from 736 healthcare facilities across KZN, of which 1,031,171 (13.5%) had detectable VLs (i.e., VLs ≥400 copies/millilitre (mL)). Of those with detectable VLs, we observed an overall decrease in HIV VLs between 2018 and 2022 (median 4.093 log10 copies/mL; 95% confidence interval (CI) 4.087-4.100 to median 3.563 log10 copies/mL; CI 3.553-3.572), p<0.01 (median test). The downward trend in proportion of HIV VLs ≥1000 copies/mL over time was accompanied by an inverse upward trend in the proportion of HIV VLs between 400 and 999 copies/mL. Moreover, specific coastal and northern districts of KZN had persistently higher VLs, with emergent hotspots demonstrating spatial clustering of high median log10 HIV VLs. The overall decrease in HIV VLs over time shows good progress towards achieving UNAIDS 95-95-95 targets in KZN, South Africa. The DTG-transition has been associated with a reduction in VLs, however, there is a need for pre-emptive monitoring of low-level viraemia. Furthermore, our findings highlight that specific districts will need intensified HIV care despite DTG rollout.

Effects of highly active antiretroviral therapy initiation on epigenomic DNA methylation in persons living with HIV.

Introduction: Highly active antiretroviral therapy (HAART) helps improve some measures of accelerated epigenetic aging in persons living with HIV (PLWH), but its overall impact on the epigenome is not fully understood. Methods: In this study, we analyzed the DNA methylation profiles of PLWH (n = 187) shortly before and approximately 2-3years after they started HAART, as well as matched seronegative (SN) controls (n = 187), taken at two time intervals. Our aim was to identify specific CpGs and biologic pathways associated with HIV infection and initiation of HAART. Additionally, we attempted to identify epigenetic changes associated with HAART initiation that were independent of HIV-associated changes, using matched HIV seronegative (SN) controls (matched on age, hepatitis C status, and interval between visits) to identify CpGs that did not differ between PLWH and SN pre-HAART but were significantly associated with HAART initiation while being unrelated to HIV viral load. Epigenome-wide association studies (EWAS) on >850,000 CpG sites were performed using pre- and post-HAART samples from PLWH. The results were then annotated using the Genomic Regions Enrichment of Annotations Tool (GREAT). Results: When only pre- and post-HAART visits in PLWH were compared, gene ontologies related to immune function and diseases related to immune function were significant, though with less significance for PLWH with detectable HIV viral loads (>50 copies/mL) at the post-HAART visit. To specifically elucidate the effects of HAART separately from HIV-induced methylation changes, we performed EWAS of HAART while also controlling for HIV viral load, and found gene ontologies associated with transplant rejection, transplant-related diseases, and other immunologic signatures. Additionally, we performed a more focused analysis that examined CpGs reaching genome-wide significance (p < 1 × 10-7) from the viral load-controlled EWAS that did not differ between all PLWH and matched SN controls pre-HAART. These CpGs were found to be near genes that play a role in retroviral drug metabolism, diffuse large B cell lymphoma proliferation, and gastric cancer metastasis. Discussion: Overall, this study provides insight into potential biological functions associated with DNA methylation changes induced by HAART initiation in persons living with HIV.

#3017 Renal-friendly lamivudine dosages are unlikely to contribute to HIV-1 shedding into PD effluents—an open label non-randomized pharmacokinetics study

Abstract Background and Aims Renally adjusted lamivudine dosages are effective. However, some of the kidney failure patients managed with lamivudine-containing regimens are failing to suppress HIV in peritoneal dialysis (CAPD) effluent. The steady-state lamivudine pharmacokinetics among these patients was evaluated. Method This overnight open-label pharmacokinetic study enrolled participants living with HIV and managed with CAPD. Lamivudine levels in blood serum and CAPD effluent samples were quantified using liquid chromatography coupled with a mass spectrometry. Pharmacokinetic measures were obtained through non-compartmental analysis. Results Twenty-eight participants were recruited with a median ARV duration of 8 (IQR, 4.5-10.5) years and a CAPD duration of 13.3 (IQR, 3.3-31.9) months. The majority, 78.6% (22/20) of participants received a 50 mg dose and 25% (1/4) had a detectable HIV viral load (HIV-VL) in CAPD, while 10.7% (3/28), and another 10.7% (3/28) received 75 mg and 300 mg dosages, respectively. Among those treated with 75 and 300 mg, 50% (2/4) and 25% (1/4) had detectable HIV-VL in CAPD, respectively. The peritoneal membrane characteristics and CAPD system strengths were variable across the entire study population. Lamivudine exposure was increased in blood serum (50 mg-AUC0-24 hours, 651.3 ng/mL; 75 mg-AUC0-24 hours, 677.84 ng/mL; 300 mg-AUC0-24 hours, 3135.89 ng/mL) compared to CAPD effluents (50 mg-AUC0-24 hours, 384.91 ng/mL; 75 mg-AUC0-24 hours, 383.24 ng/mL; 300 mg-AUC0-24 hours, 2001.60 ng/mL) among the entire study population. The Cmax (50 mg, 41.5 ng/mL; 75 mg, 53.2 ng/mL; 300 mg, 199.1 ng/mL) and Cmin (50 mg, 17.8 ng/mL; 75 mg, 16.4 ng/mL; 300 mg, 76.4 ng/mL) measured in serum were within the therapeutic levels. Conclusion Steady-state lamivudine pharmacokinetic measures were variable among the entire study population; however, the total lamivudine exposure was within the therapeutic levels.

Suicide Behavior Among Indigenous and Non-Indigenous Living with HIV: A Cross-Sectional Study in Indonesia.

Suicide remains a major public health problem, with nearly 1million deaths per year. The number tends to increase over time and factors leading to suicide suicidal behaviors are complex. However, there is a paucity of evidence on suicidal behaviors and the associated factors among people living with HIV (PLWH) in Indonesia. Therefore, this study aimed to estimate the prevalence and associated factors of suicidal behavior between indigenous and non-indigenous living with HIV who were on Dolutegravir and Efavirenz therapies. The cross-sectional data were collected using questionnaires. Participants completed the Suicidal Behaviors Questionnaire-Revised (SBQ-R), Depression Anxiety Stress Scale-42 (DASS-42), HIV Stigma-Sowell Scale, and demographic information questions. The outcome was low and high self-reported suicidal behaviors, while logistic regression analyses were used to estimate adjusted odds ratios (aOR) for associated factors of high suicidal behaviors. A total of 200 PLWH were enrolled and 8.5% of the participants had high levels of suicidal behaviors. The majority of participants were Efavirenz users (84.0%), and Papuans as Indigenous (75.5%). More than half had a high school education (60.5%), were female (58%), married (54%), and unpaid (59%). The multiple logistic regression model showed that indigenous (aOR = 0.122; 95% CI = 0.029-0.514), and people who had children (aOR = 0.221; 95% CI = 0.051-0.957) were more likely to have low suicidal behaviors. Participants who were aged 18-27 years (aOR = 5.894; 95% CI = 1.336-30.579), had high self-blame (aOR = 1.342; 95% CI) = 1.004-1.792), and detectable HIV viral load (aOR = 6.177; 95%CI = 1.118-34.119) had high suicidal behavior. This study identified the risk of suicidality among PLWHs is high and routine suicide assessment is prioritized. The findings are also useful for intervention design and the development of clinical practice guidelines to manage the well-being of PLWH such as using digital intervention to cope with hindrances.

The Potential Role of Undetectable = Untransmittable (U = U) in Reducing HIV Stigma among Sexual Minority Men in the US.

The Undetectable = Untransmittable (U = U) message and its scientific underpinnings have been widely suggested to reduce HIV stigma. However, misunderstanding and skepticism about U = U may prevent this destigmatizing potential from being fully realized. This cross-sectional study examined associations between U = U belief (belief that someone with a sustained undetectable viral load has zero risk of sexually transmitting HIV) and HIV stigma among US sexual minority men. Differences by serostatus and effects of brief informational messaging were also explored. The survey was completed online by 106 men living with HIV and 351 HIV-negative/status-unknown men (2019-2020). Participants were 18-83 years old (M[SD] = 41[13.0]). Most were non-Hispanic White (70.0%) and gay (82.9%). Although nearly all participants (95.6%) were aware of U = U, only 41.1% believed U = U. A greater percentage of participants living with HIV (66.0%) believed U = U compared with HIV-negative/status-unknown participants (33.6%). Among participants living with HIV, U = U belief was not significantly associated with perceived, internalized, or experienced HIV stigma or with viral load prejudice (prejudice against people who have a detectable HIV viral load). Among HIV-negative/status-unknown participants, U = U belief was associated with less frequently enacted HIV discrimination, more positive feelings toward people with an undetectable viral load, and lower personal endorsement of stigmatizing beliefs. Brief informational messaging about U = U did not affect most stigma dimensions and did not favorably affect any. Interventions are needed to correct commonly held, outdated misconceptions about HIV transmission risk. Such initiatives must not only engage people living with HIV but also engage HIV-negative/status-unknown people to maximize the destigmatizing potential of U = U.
