Background: As people living with HIV (PWH) age, they face new challenges that can have a negative impact on their quality of life (QOL) and mental health.

Setting: This study enrolled PWH at the end of life (EOL) who were actively engaged in cure-related research in Southern California, United States. EOL was defined as having a prognosis of 6 months or less to live. We examined the relationship between QOL, mental health, and research participation.

Methods: Structured assessments were used to collect comprehensive data on QOL and mental health.

Results: From 2017 to 2023, 35 PWH in their final stages of life who were actively engaged in cure-related research were enrolled. Their median age was 62.7 years, and most were White or otherwise non-Hispanic/non-Latino (90.6%), and male (86.7%). Changes in QOL and the presence of neurologic and psychiatric conditions, with a focus on depression and anxiety, were the primary outcomes assessed in this study. Participants had stable QOL scores throughout the study. There was an inverse relationship between QOL and Beck Depression Inventory scores, with higher mean QOL scores being associated with lower mean Beck Depression Inventory scores ( P < 0.001).

Conclusions: QOL remained stable among PWH who participate in cure-related research at EOL. The inverse relationship between QOL and depressive symptoms suggests that participation in cure-related research may improve QOL or reduce depressive symptoms in this population. Future interventions should look into ways to improve the well-being of PWH at EOL through research and customized mental health interventions.

Background: The aim of this study is to assess the acceptability of HIV preexposure 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 (1) who received their first HIV test (baseline date) between January 2018 (availability of PrEP in Italy) and December 2023 (data lock) and (2) 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 counseling and prescription according to guidelines. Characteristics of people who accepted or declined HIV PrEP were compared using Mann-Whitney or χ 2 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 = 28.7-42.4). Sexually transmitted infections were detected in 478 of 2452 (19.5%) people, most commonly gonorrhea (206/2452, 8.4%). Overall, 982 of 2452 (40.0%) people accepted PrEP, including only 3 women. Nonacceptance was higher among women ( P < 0.001) and non-White ( P < 0.001). Of those who did not accept PrEP, 260 (17.7%) were diagnosed with at least 1 sexually transmitted infection at the time of HIV testing.

Conclusions: Low PrEP acceptance was observed, particularly among women and people of non-White origin. Nonacceptance of PrEP was also observed among individuals diagnosed with an sexually transmitted infection.

Background: Maternal and pregnancy outcomes among women with perinatally acquired HIV (PHIV) versus women with HIV acquired through other routes (NPHIV) are not fully understood.

Setting: US-born women during 2005-2015 in New York City.

Methods: We used data from the New York City HIV surveillance registry, Expanded Perinatal Surveillance database, and Vital Statistics, to compare pregnancy and all-cause mortality outcomes among women with PHIV versus NPHIV delivering infants during 2005-2015.

Results: There were 186 deliveries among 137 women with PHIV and 1188 deliveries among 910 women with NPHIV. Women with PHIV were younger at delivery, more likely to be aware of their HIV status, and less likely to use substances or be incarcerated. At the time of delivery, women with PHIV were more likely to have HIV RNA >1000 copies/mL (34% vs. 19%), CD4 <200 cells/µL (18% vs. 7%; median CD4 300 cells/µL vs. 435 cells/µL), to have adequate prenatal care (43% vs. 35%), and to deliver by elective C-section (63% vs. 49%). There were no differences in intrapartum and neonatal antiretroviral therapy use, perinatal transmission, gestational age, and birth weight of the infants, nor infant mortality. Women with NPHIV had higher survival than women with PHIV (RR = 2.29, P = 0.004; age-adjusted risk ratio = 3.23, P < 0.001; age and CD4 adjusted risk ratio = 2.09, P = 0.046).

Conclusions: Women with PHIV had lower long-term survival after delivery likely because of limited HIV treatment options in childhood and a longer duration of HIV infection, underscoring the importance of close follow-up and tailored support services beyond the postpartum period.

Background: The COVID-19 pandemic had great impact on HIV care and prevention worldwide, including in Brazil. We compared HIV testing, recent infection, and annualized incidence according to the COVID-19 pandemic period among cisgender men who have sex with men (MSM) and transgender women (TGW).

Setting: HIV and sexually transmitted infection testing, prevention, and treatment referral service in Rio de Janeiro, Brazil.

Methods: We used Maxim HIV-1 Limiting Antigen Avidity EIA as part of a recent infection testing algorithm to identify recent HIV infection cases and estimate annualized HIV incidences in the pre- (March 2018-February 2020) and post-COVID-19 pandemic onset period (March 2020-January 2022). Multivariable logistic regression model assessed factors associated with recent HIV infection.

Results: Among 3814 MSM and 776 TGW, 593 (12.9%) tested positive for HIV and 119 (2.6%) were identified as having recent infection. Percentage of recent HIV infection did not differ between the COVID-19 periods. Overall annualized HIV incidence rates were 6.0% (95% confidence interval [CI]: 4.2 to 7.7) and 6.6% (95% CI: 4.3 to 9.0) in the pre- and post-COVID-19 periods, respectively. During the post-COVID-19 period, higher incidence rates were observed among TGW (8.4% [95% CI: 2.9 to 13.9]), those aged 18-24 years (7.8% [95% CI: 4.0 to 11.7]), of Black race (7.9% [95% CI: 3.8 to 12.0]), and those with <12 years of schooling (7.8% [95% CI: 4.8 to 10.8]). Compared to the pre-COVID-19 period, incidence rates were significantly higher in the post-COVID-19 period for those aged >30 years and TGW, while being lower for those with more years of schooling.

Conclusion: HIV incidence estimates remain high among MSM and TGW in Brazil, especially among the most vulnerable. The consequences of the COVID-19 pandemic on the HIV epidemic will likely persist and contribute to worsening HIV outcomes.

Background: The Veterans Aging Cohort Study (VACS) Index is a summary measure of routinely obtained clinical variables that predicts numerous health outcomes. Since there are currently no tools to predict acute kidney injury (AKI) in persons with HIV (PWH), we investigated the association of preadmission VACS Index with hospital AKI in PWH.

Methods: We conducted an observational study of PWH hospitalized in a New York City health system between 2010-2019. The VACS Index, calculated using outpatient laboratory values within 8-365 days of admission, was examined continuously and in quartiles. Multivariable Cox proportional hazards models, adjusting for sociodemographic factors, comorbidities, and ICU admission, determined the association of the VACS Index with AKI.

Results: Among 1,186 PWH, median age was 53, 43.5% were women, 86.2% were Hispanic or Black, 23.1% were coinfected with hepatitis C, and 65% were virally suppressed (<200 copies/mL). Overall AKI incidence was 20.9%. The proportion with AKI was higher by increasing VACS index quartile: 10.7%, 18.6%, 28.1% and 60.7% in quartiles 1-4, respectively. There was a graded, independent association of VACS Index quartile with AKI. Compared to those in the lowest quartile, the adjusted relative hazard of AKI was 1.55, 1.92, and 3.07 times higher in quartiles 2-4, respectively (P for trend <0.001).

Conclusion: Preadmission VACS Index is associated with hospital AKI. Use of the VACS Index may allow for early identification of PWH at risk for AKI and initiation of preventative strategies. These findings should be externally validated in other health systems, including its predictive performance in specific hospital settings.

Background: Most infants born to women living with HIV (WLH) are HIV-exposed but uninfected exposed infants have poorer growth than HIV-unexposed uninfected children. Few large studies have compared children who are exposed (CHEU) and unexposed (CHUU) in the era of dolutegravir (DTG)-based antiretroviral treatment (ART).

Setting: Longitudinal study of mother-infant CHEU and CHUU pairs in Nairobi and Western Kenya.

Methods: Mother-infant pairs were enrolled at 6 weeks postpartum with 6-monthly growth assessments. We compared longitudinal growth between CHEU and CHUU infants during the first year and assessed biological and social factors affecting growth (length and weight-for-age z-scores [LAZ, WAZ] and weight for length z-scores [WLZ]) and stunting (LAZ<-2), underweight (WAZ<-2), and wasting (WLZ<-2) from birth to 1 year.

Results: Among 2000 infants (1000 CHEU and 1000 CHUU), CHEU infants had significantly lower LAZ at 6 months (-0.165 (95% CI: -0.274, -0.056), p-value = 0.003) and 12 months (-0.195, 95% CI:-0.294, -0.095, p-value = 0.0001; n = 1616). CHEU infants had a higher prevalence of stunting at 6 months compared to CHUU infants (Prevalence Ratio: 1.45, 95% CI: 1.14, 1.85). Among all children, greater maternal BMI, education, and caregiver-perceived social support were positively associated with growth. Higher maternal and infant comorbidities were associated with growth deficits for CHEU infants. Among CHEU, ART timing (before versus during pregnancy) and ART regimen (dolutegravir(DTG)-based, efavirenz-based, and protease inhibitor/other) did not affect growth.

Conclusion: Growth deficits among CHEU persist, despite DTG-based ART. Addressing comorbidities, amplifying social support, and education may improve growth outcomes.

Background: Previous studies have estimated preexposure prophylaxis (PrEP) use among persons with commercial health insurance and Medicaid. However, data are lacking regarding PrEP use among those with Medicare.

Methods: Using a previously developed algorithm, we estimated the number of Medicare beneficiaries (MBs) with fee-for-service (FFS) claims who were prescribed PrEP from 2014 to 2021. The analysis was stratified by age, sex, and race/ethnicity. We also examined trends in PrEP prevalence by U.S. state and demographic characteristics during 2014-2021.

Results: The number of Medicare PrEP users increased 11-fold, from 388 in 2014 to 4,685 in 2021. MBs prescribed PrEP were predominantly younger men, White persons, residing in the South or West regions, living with a disability, and dually eligible for both Medicare and Medicaid. The prevalence of PrEP prescriptions among MBs increased 12-fold, from 9.7 per million in 2014 to to 120.0 per million in 2021. Black/African American persons had the highest prevalence of PrEP use, followed by Hispanic/Latino and White persons in 2021. The District of Columbia had the highest prevalence of PrEP use compared with other U.S. states in 2021. Significant increasing trends in PrEP use were observed across sex, age groups, and race/ethnicity.

Conclusions: Disparities in PrEP uptake existed across MB demographic subgroups from 2014 to 2021. Public health interventions are needed to increase PrEP access and utilization, particularly among women, younger MBs, Black persons, and Hispanic persons, including those with Medicare. Strategies and policies to expand PrEP use are essential for optimal HIV prevention in the United States.

Background: Long-acting injectable (LAI) antiretroviral medications are as effective as daily oral antiretroviral therapy (ART) and offer discreet, less frequent dosing. LAIs may be ideal treatment options for people who experience challenges with adherence to daily oral ART, including mobile men living with HIV (MLHIV).

Methods: We conducted a qualitative substudy within two parent trials in 24 health facilities in Malawi that enrolled MLHIV ≥15 years not on ART. We conducted in-depth interviews with a stratified random sample of participants who had taken oral ART and self-reported mobility (travel) during the 6-month study (≥1 trip of ≥3 nights). Interviews described cabotegravir/rilpivirine and asked about clients' stated preferences for LAI vs. oral ART and their reasoning. Interviews were translated, transcribed, coded in Atlas.ti, and analyzed using framework analysis.

Results: We interviewed 29 mobile MLHIV from July 1, 2022, to August 30, 2022, median age 36 years (interquartile range: 31-41), mean 28 nights away in the past 6 months (SD: 40). Nearly all participants (26/29) expressed a preference for LAI over daily oral ART because LAI would reduce the risks of forgetting to take pills and unwanted disclosure. Three men preferred oral ART primarily because of fear of side effects from a new medication. A few men reported they would change their preference if injection site reactions prevented them from working.

Conclusions: Mobile MLHIV in Malawi with previous ART adherence challenges expressed strong stated preferences for LAI over daily oral ART. Further research is needed to understand implementation challenges and potential effectiveness of LAI among harder-to-reach populations.

Background: HIV type 1 ((human immunodeficiency virus) HIV-1) elite controllers (ECs) are a rare subset of people living with HIV-1 (PLWH) who control viral replication in the absence of antiretroviral treatment (ART) and may provide a model for a functional cure. We investigated the role of natural killer (NK) cells in HIV-1 ECs from South Africa.

Methods: Phenotypic (CD69, CD38, CD57, PD-1), functional (CD107a, IFN-γ (inferferon gamma)), and nutrient transporter profiles (glucose transporter 1, CD98) of NK cells from ECs (n = 20), viremic progressors (VPs; n = 19), PLWH on ART (n = 20), and people without HIV-1 (PWOH; n = 21) were analyzed using flow cytometry. The Kruskal-Wallis test and followed by the Mann-Whitney U test were used to determine differences among the study groups. The Spearman rank correlation coefficient was used to determine significant associations.

Results: Compared with the other study groups, the percentage of CD69-expressing NK cells was higher in ECs, whereas the percentage of CD38-expressing NK cells was higher in VPs. Percentages of CD69 + CD38 - NK cells were elevated in ECs compared with VPs ( P = 0.003), but were not different to PLWH on ART and PWOH. Differentiation, exhaustion, and metabolic profiles were not different in ECs compared with PLWH on ART and PWOH; however, NK cell function was lower than in PWOH.

Conclusions: These findings demonstrate that NK cells from ECs have an activated, mature profile with low levels of immune exhaustion and a reduced metabolic phenotype suggesting functional competence. This insight could inform the development of novel immunotherapeutic strategies for treating HIV-1.
