Objective: To ascertain whether a novel expanded social network recruitment to HIV testing (E-SNRHT) intervention recruits men and individuals with previously-undiagnosed HIV at higher rates than risk network recruitment.

Design: Initial "seed" participants were prospectively randomly assigned to the E-SNRHT intervention or to risk network recruitment. Their network members were included in the study arm of their recruiter.

Setting: Three Department of Health clinics and two drug treatment centers (DTCs) in the Msunduzi municipality of KwaZulu-Natal, South Africa.

Participants: Clinics and DTCs referred 110 newly-HIV-diagnosed adult "seeds" to the study from June 2022-February 2023. E-SNRHT seeds were asked to recruit network members as described below; risk network recruitment arm seeds were asked to recruit recent sex and/or injection partners. Presenting a recruitment coupon (from clinic/DTC staff or another participant) was required for eligibility.

Intervention: E-SNRHT seeds were shown educational material about HIV transmission risks and then asked to recruit anyone they know (e.g., friends, family) whom they thought could benefit from HIV testing.

Main outcome measures: Rates of recruiting men to HIV testing and locating individuals with previously-undiagnosed HIV.

Results: E-SNRHT recruited significantly higher proportions of men to HIV testing (70.3% vs. 40.4%; χ2 = 16.33; p < .0005) and located significantly more previously-undiagnosed cases of HIV per seed than risk network recruitment (rate ratio = 9.40; p < .0001). E-SNRHT also recruited significantly higher proportions of women with previously-undiagnosed HIV (29.0% vs. 10.7%; χ2 = 3.87; p = .049).

Conclusions: E-SNRHT is an important strategy to expand the reach of HIV testing among men and undiagnosed cases of HIV in KwaZulu-Natal.

Background: The methamphetamine epidemic threatens progress towards ending the HIV epidemic in the United States. Further characterizing the prevalence and impact of methamphetamine use among people with HIV (PWH) is necessary to inform integrated HIV and methamphetamine treatment strategies.

Methods: We conducted a retrospective chart review to characterize methamphetamine use among 3,092 PWH at an urban HIV Medicine clinic between July 1, 2022 and June 30, 2023. The Chi-squared test was utilized to assess for statistically significant differences in demographics and HIV and other health outcomes among PWH who use and do not use methamphetamine.

Results: The prevalence of methamphetamine use among PWH in this cohort was 17%. PWH who used methamphetamine were more likely to be < 40 years of age, identify as White race, live in neighborhoods with low Healthy Places Index scores, identify as lesbian, gay, or bisexual, report male sex with men (MSM), MSM and injection drug use (IDU), or IDU as HIV transmission risk factor, miss scheduled HIV primary care visits, and screen positive for hepatitis C virus antibody, gonorrhea, chlamydia, and major depressive disorder. PWH who use methamphetamine were also less likely to be virally suppressed and have a CD4 count ≥ 200 cells/mm3.

Conclusion: Methamphetamine use is prevalent among PWH at this urban HIV Medicine Clinic and is associated with worse HIV and other health outcomes which likely increase the risk of HIV transmission. The integration of methamphetamine use disorder treatment into HIV primary care is necessary to work toward ending the syndemics of methamphetamine and HIV.

Objective: Children and adolescents with HIV infection are well known to face a heightened risk of tuberculosis. However, the exact mortality rates and temporal trends of those with HIV-tuberculosis (TB) co-infection remain unclear. We aimed to identify the overall mortality and temporal trends within this population.

Methods: PubMed, Web of Science, and Embase were employed to search for publications reporting on the mortality rates of children and adolescents with HIV-TB co-infection from inception to March 2, 2024. The outcome is the mortality rate for children and adolescents with HIV-TB co-infection during the follow-up period. In addition, we evaluate the temporal trends of mortality.

Results: During the follow-up period, the pooled mortality was 16% [95% confidence interval (CI) 13-20]. Single infection of either HIV or TB exhibit lower mortality rates (6% and 4%, respectively). We observed elevated mortality risks among individuals aged less than 12 months, those with extrapulmonary TB, poor adherence to ART, and severe immunosuppression. In addition, we observed a decreasing trend in mortality before 2008 and an increasing trend after 2008, although the trends were not statistically significant ( P  = 0.08 and 0.2 respectively).

Conclusions: Children and adolescents with HIV-TB co-infection bear a significant burden of mortality. Timely screening, effective treatment, and a comprehensive follow-up system contribute to reducing the mortality burden in this population.

Objective: We assessed the association and concordance between self-reported oral pre-exposure prophylaxis (PrEP) intake in a diary app and intraerythrocytic drug metabolite concentrations.

Design: AMPrEP was a prospective demonstration study providing daily and event-driven PrEP to MSM in Amsterdam, the Netherlands (2015-2020).

Methods: Participants could record their PrEP intake in a diary app. Dried blood spots (DBS) were taken at 6, 12, 24, and 48 months and analysed for tenofovir diphosphate (TFV-DP) and emtricitabine triphosphate (FTC-TP) concentrations. We included TFV-DP measurements preceded by diary completion on at least 90% of days in the 6 weeks prior. We examined the association between self-reported PrEP intake (i.e. number of pills) and TFV-DP concentrations using tobit regression with a random intercept per participant. We also calculated concordance between categorized PrEP intake (i.e. <2, 2-3, 4-6 or 7 pills per week) and categorized TFV-DP concentrations (i.e. <350, 350-699,700-1249 or ≥1250 fmol/punch) using weighted Cohen's kappa. Last, we calculated concordance between self-reported recent PrEP intake (yes/no, in past 2 days) and quantifiability of FTC-TP (yes/no) using Cohen's kappa.

Results: Seven hundred and fifty-nine DBS measurements from 282 MSM were included. Self-reported PrEP intake was strongly and positively associated with TFV-DP concentration ( β  = 0.77, 95% CI = 0.70-0.84, P  < 0.0001). Concordance between categorized PrEP intake and TFV-DP concentration was moderate ( κ  = 0.44, 95% CI = 0.39-0.50). Concordance between self-reported recent PrEP intake and FTC-TP quantifiability was perfect ( κ  = 0.83, 95% CI 0.76-0.90).

Conclusion: Self-reported PrEP intake in a diary app is strongly correlated with actual use, and therefore reliable for comparing PrEP adherence between groups. Still, suboptimal criterion validity according to clinically relevant categories warrants caution when assessing 6-week reported adherence for individuals.

In a retrospective study conducted in three hospitals in Paris, generic antiretroviral accounted for 30.2% of all prescriptions. Tenofovir disoproxil/emtricitabine (TDF/FTC) was the most prescribed generic ART (82.3% of generic prescriptions). Generic ART (gART) was more likely to be prescribed to women, to patients less than 50 years, and with recent HIV diagnosis less than 3 years. Physicians prescribed more gART if they were men, older than 55 years or worked at a university teaching hospital.

Objectives: To evaluate associations between self-rated health (SRH) and care outcomes among United States adults with diagnosed HIV infection.

Design: We analyzed interview and medical record data collected during June 2020-May 2021 from the Medical Monitoring Project, a complex, nationally representative sample of 3692 people with HIV (PWH). Respondents reported SRH on a 5-point Likert type scale (poor to excellent), which we dichotomized into "good or better" and "poor or fair". We computed weighted percentages with 95% confidence intervals (CIs) and age-adjusted prevalence ratios (aPRs) to investigate associations between SRH and HIV outcomes and demographic, psychosocial, and behavioral characteristics.

Results: Nationally, 72% of PWH reported "good or better" SRH. PWH with the following characteristics had a lower prevalence of "good or better" SRH, compared with those without: any missed HIV care appointment in the last 12 months (aPR 0.86, 95% CI: 0.81-0.91), symptoms of moderate or severe depression (aPR 0.51, 95% CI: 0.43-0.59) and anxiety (aPR 0.60, 95% CI: 0.54-0.68), unstable housing or homelessness (aPR 0.77, 95% CI: 0.71-0.82), and hunger or food insecurity (aPR 0.74, 95% CI: 0.69-0.80), as well as having a mean CD4 count <200 cells/mm 3 vs. CD4 + >500 cells/mm 3 (aPR 0.70, 95% CI: 0.57-0.86).

Conclusions: Though SRH is a holistic measure reflective of HIV outcomes, integrated approaches addressing needs beyond physical health are necessary to improve SRH among PWH in the United States. Modifiable factors like mental health, unstable housing or homelessness, and food insecurity warrant further study as potential high-yield targets for clinical and policy interventions to improve SRH among PWH.

Objective: To estimate the relative rate of all-cause mortality amongst those on antiretroviral treatment (ART) with a history of interruptions compared with those with no previous interruptions in care.

Design: Retrospective cohort study.

Methods: We used data from four South African cohorts participating in the International epidemiology Databases to Evaluate AIDS Southern Africa collaboration. We included adults who started ART between 2004 and 2019. We defined a care interruption as a gap in contact longer than 180 days. Observation time prior to interruption was allocated to a 'no interruption' group. Observation time after interruption was allocated to one of two groups based on whether the first interruption started before 6 months of ART ('early interruption') or later ('late interruption'). We used Cox regression to estimate hazard ratios.

Results: Sixty-three thousand six hundred and ninety-two participants contributed 162 916 person-years of observation. There were 3469 deaths. Most participants were female individuals (67.4%) and the median age at ART initiation was 33.3 years (interquartile range: 27.5-40.7). Seventeen thousand and eleven (26.7%) participants experienced care interruptions. Those resuming ART experienced increased mortality compared with those with no interruptions: early interrupters had a hazard ratio of 4.37 (95% confidence interval (CI) 3.87-4.95) and late interrupters had a hazard ratio of 2.74 (95% CI 2.39-3.15). In sensitivity analyses, effect sizes were found to be proportional to the length of time used to define interruptions.

Conclusion: Our findings highlight the need to improve retention in care, regardless of treatment duration. Programmes to encourage return to care also need to be strengthened.
