Background: Screening for depression remains a priority for people living with HIV (PLWH) accessing care. The nine-item Patient Health Questionnaire (PHQ-9) is a widely used depression screening tool, but has limited accuracy when applied across various cultural contexts. We aimed to evaluate the performance of alternative PHQ-9 scoring algorithms in sub-Saharan African PLWH.

Setting: five HIV programs in Cameroon, Côte d'Ivoire, Kenya, Senegal and the Republic of Congo.

Methods: Adult PLWH were screened for depression during the 2018-2022 period. Diagnosis confirmation was done by psychiatrist blinded clinical evaluation (gold standard). Diagnostic performances, including sensitivity, and area under the curve (AUC)) of the traditional PHQ-9 scoring (positive screening - score≥10) was compared to alternative scoring algorithms including: i) the presence of ≥1 mood symptom (PHQ-9 items 1&2) combined with ≥2 other symptoms listed in the PHQ-9, and ii) a simplified recoding of each 4-response item into two categories (absence/presence).

Results: A total of 735 participants were included (54% female, median age 42 years [IQR 34-50]). Depression was diagnosed by a psychiatrist in 95(13%) participants. Alternative scoring sensitivities (0.59 to 0.74) were higher than that of the traditional score's (0.39). Compared to traditional scoring, AUC were significantly higher for PHQ-9 alternative scoring. Across settings, alternative scoring algorithms increased sensitivity and reduced variability.

Conclusion: As a primary screening test, new scoring algorithms appeared to improve the PHQ-9 sensitivity in identifying depression and reduce heterogeneity across settings. This alternative might be considered to identify PLWH in need of referral for further diagnostic evaluations.

Background: Little is known about the effect of HCV treatment on sexual risk behaviour among men who have sex with men (MSM) with HIV by treatment type (IFN-based vs DAA-based).

Setting: MSM with HIV and recently acquired HCV infection enrolled in the observational MOSAIC cohort.

Methods: Using data from 2009-2018, we evaluated risk behaviour through a validated HCV risk score (where ≥2 indicated high risk) and its individual risk behaviours. Levels of risk behaviour before, during and after treatment were modelled for each treatment episode using linear and logistic regression with Generalized Estimating Equations adjusting for DAA availability and number of re-infections.

Results: 140 MSM with a median age of 45 years (interquartile range=40-49) yielded 180 treatment episodes (n=131 IFN-based, n=49 DAA-based). Adjusted mean risk score before, during and after treatment was 2.4 (95% confidence interval (CI)=2.1-2.6), 0.9 (95%CI=0.8-1.0) and 1.7 (95%CI=1.5-1.8), respectively. Before treatment, no differences in mean HCV risk score or proportion of specific behaviours were found between the regimen groups. During treatment, MSM treated with DAAs had a higher average risk score and proportion of receptive condomless anal sex, sharing toys and unprotected fisting than those treated with IFN. After treatment, the proportion sharing straws were significantly higher in MSM treated with DAAs than IFN.

Conclusions: MSM treated with DAAs, compared to IFN, had higher levels of HCV-related risk behaviour during treatment. The higher risk of HCV re-infection in the DAA-era underscores the need for ongoing HCV testing and behavioural interventions against HCV.

Background: Discussion of HIV and other sexually transmitted infections (STIs) among sex partners facilitates risk reduction. We evaluated HIV/STI-related communications, including broad assessment of any self-reported discussion of the topic and specific discussion of each partners' HIV status, among a historically marginalized and presently criminalized community of sexual and gender minorities (SGM) in Nigeria.

Methods: From 2013-2018, we enrolled SGM aged 18+ in Lagos or 16+ in Abuja who reported anal sex with men. At enrollment and 3-, 9-, and 15-month follow-up visits, participants were asked about their sexual behaviors and communications with main sexual partners (MSP) and casual sexual partners (CSP). Questions included "have you talked with your [MSP/CSP] about sexually transmitted infections and HIV?" Multivariable robust Poisson regression with generalized estimating equations was used to estimate adjusted relative risks (aRRs) and 95% confidence intervals (CIs) for factors potentially associated with HIV/STI-related communications with some or all of each type of sexual partner.

Results: Among 2795 SGM enrolled with median age 23 years (interquartile range 20-27), questions about HIV/STI-related communications with MSP were answered by 2436 (87.2%) and with CSP by 2398 (85.9%). Communication with MSP was reported by 68.1% (1659/2436), of whom 897 (54.1%) discussed their own HIV status and 925 (55.8%) discussed their partner's status. Communication with CSP was reported by 43.9% (1052/2398), of whom 389 (37.0%) discussed their own HIV status and 385 (36.6%) discussed their partner's status. Among participants with both MSP and CSP, HIV/STI-related communication with MSP was more common among participants with higher than secondary education (aRR 1.40 [95%CI 1.24-1.58)], who were divorced/separated/widowed (aRR 1.19 [95% CI 1.06-1.33]), who discussed their HIV status with CSP (aRR 1.18 [95%CI 1.10-1.25]), discussed CSP's HIV status (aRR 1.20 [95%CI 1.13-1.27]), and used a condom at last sex with CSP (aRR 1.16 [95%CI 1.08-1.25]). HIV/STI-related communication with CSP was more common among participants with higher than secondary education (aRR 1.36 [95%CI 1.12-1.66]); who were divorced/separated/widowed (aRR 1.38 [95%CI 1.13-1.69]), who discussed their HIV status with MSP (aRR 1.47 [95%CI 1.27-1.69]), who discussed CSP's HIV status (aRR 1.22 [95%CI 1.06-1.40]) and used a condom at last sex with CSP (aRR 1.22 (95%CI 1.08-1.38]).

Conclusion: HIV/STI-related communications with main and casual sex partners were both associated with safer sex with CSP. HIV prevention and treatment programs for SGM should promote open communications in sexual relationships and consider deployment of modern strategies to facilitate disclosure, especially in settings with criminalizing legislation.

Background: To address the need for improved virologic suppression among youth living with HIV (YLH) on antiretroviral treatment (ART), we evaluated peer navigation plus TXTXT daily text message ART reminders.

Setting: YLH aged 15-24 on ART for at least 3 months at six research sites in four Nigerian cities.

Methods: Using a stepped-wedge design, Cluster 1 was non-randomized, while Clusters 2 and 3 were randomized to sequences of routine care (control period) and 48 weeks of the combination intervention (intervention period). The primary endpoint was viral suppression (HIV-1 RNA <200 copies/mL) at week 48 of the intervention. Secondary endpoints included adherence measured by self-report (90% considered adherent). Post-hoc analysis assessed virologic control at <50 copies/mL and <1000 copies/mL. Generalized estimating equations determined the difference between intervention and control periods in the intention-to-treat population.

Results: We enrolled 558 YLH and followed 541 over time, mean age 18 years, 53.8% female, 71.7% perinatally infected, and 38.6% virologically non-suppressed at enrollment. For the primary endpoint, the intervention periods displayed a small, non-significant increase in viral suppression < 200 copies/mL (OR = 1.16 [0.88, 1.54], p = 0.297). There was a significant effect of the combination intervention on virologic control <1000 copies/mL (OR = 1.42 [1.03, 1.94], p = 0.030). Self-reported adherence also improved (OR = 2.07 [1.46, 2.95], p < 0.001).

Conclusion: Peer navigation plus daily text message ART reminders demonstrated limited benefit among ART-experienced, predominantly perinatally-infected YLH, with no significant effect on viral suppression below 200 copies/mL despite improvement in self-reported adherence.

Background: Comorbidities such as schizophrenia and medication such as antipsychotics may influence the risk of dementia among people living with HIV (PLWH). The objective of this paper is to assess the associations among HIV patients with schizophrenia, off-label antipsychotics, and dementia risk.

Setting: US Department of Veterans Affairs healthcare facilities from 2000 to September 2023.

Methods: Retrospective cohort study of PLWH treated by the U.S. Department of Veterans Affairs with prior history of schizophrenia, off-label antipsychotic use and neither schizophrenia nor antipsychotic use. Propensity score matched non-HIV controls were included for the respective HIV groups. The hazard of dementia is estimated using Cox proportional hazards models.

Results: PLWH and schizophrenia, were found to have a 2.49 higher hazard of dementia compared to HIV patients with no history of schizophrenia or antipsychotic medication use (HR=2.49, 95%CI=(1.85-3.35)). PLWH and off-label antipsychotic use were found to have a 1.77-fold higher hazard of dementia compared to HIV patients with no history of schizophrenia or antipsychotic medication use (HR=1.77, 95% CI=(1.37-2.28)). Propensity score matched analysis reveals that, among schizophrenia patientis, those with HIV had a 1.65-fold higher hazard of dementia (HR=1.65, 95%CI=(1.12-2.44)). Among patients with no schizophrenia or antipsychotic medication, those with HIV had a 1.47 fold higher hazard of dementia (HR=1.47, 95%CI=(1.33-1.63)).

Conclusions: This study demonstrates that among PLWH, history of schizophrenia or off-label antipsychotic medication use are associated with substantial increases in dementia incidence. Furthermore, propensity-matched control analysis reveals that HIV infection itself is independently and significantly associated with elevated dementia risk.

Introduction: Within the United States, individuals experiencing incarceration are at higher risk for HIV acquisition compared to the general population, yet may face additional difficulty engaging in HIV prevention clinical services. HIV pre-exposure prophylaxis (PrEP) is an effective approach to preventing HIV transmission, and the Centers for Disease Control (CDC) recommends that PrEP be offered in carceral settings, particularly during the vulnerable community re-entry period. However, there have been few efforts to scale PrEP in this setting.

Methods: Based on our experience implementing PrEP in Rhode Island's state carceral system, we have identified potential approaches to overcoming barriers to PrEP use in this unique practice environment by utilizing the implementation research logic model (IRLM). We then evaluated specific implementation determinants and barriers as well as strategies used to overcome those barriers to effectively scale PrEP in this setting.

Results: We developed a "toolkit," or 14-step guide, for others in the field to use for implementing PrEP in carceral settings including the development and use of clinical protocols as well as community linkage strategies.

Discussion: Our experiences with barriers in the carceral setting, identifying and leveraging implementation strategies, allowed us to develop a "toolkit" to guide other PrEP implementation projects in carceral settings. We encourage others to scale-out our work to other carceral settings to better reach and engage a group of individuals both at elevated risk for HIV and currently underserved by HIV prevention strategies, including PrEP.

Background: The aim of this study is to assess the acceptability of HIV pre-exposure prophylaxis (PrEP) among individuals eligible for prophylaxis.

Setting: Retrospective study of individuals receiving their first HIV test at the Infectious Diseases Unit of IRCCS San Raffaele Scientific Institute, Milan, Italy.

Methods: People i) who received their first HIV test (baseline date) between January 2018 (availability of PrEP in Italy) and December 2023 (data lock), ii) with an indication for PrEP based on condomless sex were included; those already on PrEP were excluded. Individuals with a negative HIV test result were offered PrEP counselling and prescription according to guidelines. Characteristics of people who accepted or declined HIV PrEP were compared using Mann-Whitney or Chi-square tests, as appropriate.

Results: A total of 2627 people were tested for HIV: 175 (6.6%) were diagnosed with HIV. Of the 2452 people with negative HIV test results, 2165 (88.3%) were men; median age was 34.3 years (interquartile range, IQR=28.7-42.4). Sexually transmitted infections (STIs) were detected in 478/2452 (19.5%), most commonly gonorrhoea (206/2452, 8.4%). Overall, 982/2452 (40.0%) people accepted PrEP, including only three women. Non-acceptance was higher among women (p<0.001) and non-Caucasians (p<0.001). Of those who did not accept PrEP, 260 (17.7%) were diagnosed with at least one STI at the time of HIV testing.

Conclusion: Low PrEP acceptance was observed, particularly among women and people of non-Caucasian origin. Non-acceptance of PrEP was also observed among individuals diagnosed with an STI.

Background: To compare racial and ethnic disparities in HIV diagnosis rates among adults in census tracts with most disadvantaged vs advantaged levels of social determinants of health (SDOH).

Methods: In this ecological analysis, we used the National HIV Surveillance System data in 2021 and SDOH data from 2017-2021 American Community Survey. We measured racial and ethnic disparities stratified by sex in the most disadvantaged quartiles and advantaged quartiles for: 1) Poverty 2) Education level 3) Median household income and 4) Insurance coverage. We calculated 8 relative disparity measures (Black-to-White rate ratio [RR], Hispanic/Latino-to-White RR, Index of Disparity [ID], population-weighted ID, Mean Log Deviation, Theil Index, Population Attributable Proportion, Gini coefficient) and 4 absolute disparity measures (Black-to-White rate difference [RD], Hispanic/Latino-to-White RD, absolute ID, and population-weighted absolute ID).

Results: Comparing the most disadvantaged quartiles to the most advantaged quartiles, all four absolute disparity measures decreased, but 7 of the 8 relative disparity measures increased: the median percentage decrease in the absolute measures for males and females respectively was 38.1% and 47.6% for poverty, 12.4% and 42.6% for education level, 43.6% and 44.0% for median household income, and 44.2% and 45.4% for insurance coverage. The median percentage increases for the relative measures for males and females respectively were 44.3% and 61.3% for poverty, 54.9% and 95.3% for education level, 19.6% and 90.0% for median household income, and 32.8% and 46.4% for insurance coverage.

Conclusion: Racial and ethnic disparities in the most disadvantaged and advantaged quartiles highlight the need for strategies addressing the root causes of disparities.
