Factors Associated with Transition of HIV Care Readiness Among Adolescents and Youth from a Specialty Pediatric HIV Clinic in the United States.

Transitioning from pediatric to adult services is known to be associated with worsening of health outcomes and decreased retention in care among adolescents and youth living with HIV (AYLHIV). We aimed to identify factors associated with HIV care transition readiness among AYLHIV in care at a pediatric HIV clinic in Washington, DC. This retrospective cohort study from June 2019 through January 2021 collected demographic and clinical characteristics from the clinic database. We adapted the Transition Readiness Assessment Questionnaire (TRAQ; scored 1-4; 1 being the lowest level of preparedness) to evaluate transition readiness over time. We analyzed data using two-sided unadjusted two-sample and paired t-tests and adjusted analysis of variance (ANOVA). We included 103 AYLHIV (50.49% female; 100% non-Hispanic Black/African American; mean age = 19.54 ± 2.78 years; 81.55% virally suppressed). Mean baseline TRAQ score (2.32 ± 0.78) was associated with age (p < 0.0001), gender (p = 0.033), mode of HIV transmission (p = 0.0005), viral suppression (p = 0.0033), and duration of HIV diagnosis (p = 0.012). AYLHIV diagnosed with HIV within the prior year experienced significantly greater mean improvement in transition readiness compared with those living with HIV for >10 years (p = 0.013). Adjusted for covariates, older age (p < 0.0001), undetectable viral load (p = 0.0008), and presence of mental health condition(s) (p = 0.020) were associated with higher TRAQ scores. Lower improvement in transition readiness among youth with a longer history of HIV suggests that AYLHIV with perinatally acquired HIV might require additional support than those with horizontally acquired HIV.

Awareness of and Attitudes Toward Pre-exposure Prophylaxis Among Predominantly Heterosexual Black Adolescents and Young Adults and Their Guardians in an Urban Area With HIV Epidemic in the United States.

Among 185 Black, cis-gender, predominantly heterosexual adolescents and young adults (AYA) and 35 guardians surveyed in Washington, DC, the majority of AYA (96.8%) and guardians (94.3%) were unaware of pre-exposure prophylaxis (PrEP); 62.2% of AYA were uncertain if PrEP was safe or effective against HIV. Of 41.6% of AYA willing to use PrEP, 24.9% reported concern about PrEP-related social stigma.

Prevention of Perinatal HIV Transmission in an Area of High HIV Prevalence in the United States.

OBJECTIVE: To evaluate the uptake of perinatal HIV preventive interventions by the risk of perinatal HIV transmission in mother-infant pairs in a high-HIV prevalence area in the US. STUDY DESIGN: This was a retrospective cohort study of mother-infant pairs with perinatal HIV exposure during 2013-2017 managed at a subspecialty pediatric HIV program in Washington, DC. We collected demographic data, maternal HIV history, delivery mode, maternal and infant antiretroviral drug (ARV) use, and infant HIV test results. We compared the uptake of recommended preventive interventions in low-risk (ie, mothers on antiretroviral therapy [ART] with viral suppression) and high-risk (mothers without ART or viral suppression) mother-infant pairs using the Pearson chi-square, Fisher exact, and Wilcoxon rank-sum tests and logistic regression. RESULTS: We analyzed 551 HIV-exposed infants (HEIs) and 542 mothers living with HIV. The majority of mothers received ARVs (95.5%), had HIV RNA ≤1000 copies/mL before delivery (81.9%), and received intrapartum zidovudine (ZDV; 65.5%). The majority of all HEIs were low risk (82.6%) and received postpartum ARVs (98.9%). Among the low-risk infants, 53.2% were delivered via cesarean delivery (CD), and 62.9% and 96.5% were administered intrapartum and postpartum ZDV, respectively. Among high-risk infants, 84.4% were delivered via CD, 78.1% received intrapartum ZDV, and 62.5% received combination ART. Nine high-risk infants acquired HIV perinatally. CONCLUSION: In an area of high HIV prevalence in the US, a large proportion of low-risk HEIs received intrapartum ZDV and were delivered via CD. We also observed missed opportunities for the prevention of perinatal HIV transmission.

HIV-Associated CKDs in Children and Adolescents.

INTRODUCTION: Limited information is available describing the current prevalence of proteinuria and HIV-associated CKDs (HIV-CKDs) in children and adolescents living with HIV and receiving antiretroviral therapy in the United States. METHODS: To address this issue, we performed a retrospective study of children and adolescents living with HIV who received medical care at Children's National Hospital in Washington, DC, between January 2012 and July 2019. Demographic data, clinical parameters (mode of HIV transmission, viral loads, CD4 cell counts, serum creatinine, glomerular filtration rate [GFR], plasma lipid levels, proteinuria, blood pressure, renal biopsies), and medical treatments, all done as a standard of clinical care, were collected and analyzed. RESULTS: The majority of the 192 patients enrolled were of African descent (88%) and acquired HIV through vertical transmission (97%). The prevalence of all HIV-CKDs was 6%. Of these patients, 39% had intermittent or persistent proteinuria, and 7% percent had proteinuria with a mild decline in GFR (60-80 ml/min per 1.73 m2), and 6% had a mild decline in GFR without proteinuria. Documented hypertension was present in 6% of the patients, mainly in association with HIV-CKD. Patients with persistent proteinuria (3%) and biopsy-proven HIV-CKD had a slow but constant progression of their renal diseases. CONCLUSIONS: The prevalence of persistent proteinuria and HIV-CKD was lower than that reported in previous studies conducted in the United States. However, intermittent proteinuria, mild reductions in GFR, and progression of established HIV-CKD were common findings in this group of patients with predominantly vertically acquired HIV who were receiving antiretroviral therapy.

Outcomes of Integrase Inhibitor-based Antiretroviral Therapy in a Clinical Cohort of Treatment-experienced Children, Adolescents and Young Adults With HIV Infection.

BACKGROUND: Data on integrase strand transfer inhibitor (INSTI) use in children, adolescents and young adults with HIV are limited. We evaluated virologic and safety outcomes following INSTI initiation among treatment-experienced children, adolescents and young adults. METHODS: The DC Cohort is a multicenter observational study of individuals receiving HIV care in Washington, DC. This analysis included treatment-experienced participants 0-24 years of age who initiated an INSTI during 2011-2017. Viral suppression (VS) and safety outcomes were quantified. Differences in VS by age, sex and CD4 count were assessed using Kaplan-Meier curves. RESULTS: Of 141 participants (median age 20 years; 35% <18 years; 60% male; 89% Black; 62% perinatally-infected), 35% had VS and 65% lacked VS on INSTI initiation. Dolutegravir was the most commonly prescribed INSTI (55%). Among participants without VS at INSTI initiation, 46% achieved VS after a median of 2.7 months. Participants 13-24 (vs. 0-12) years old (P = 0.011) and participants with CD4 counts <350 (vs. >500) cells/µL were less likely to achieve VS (P < 0.001). Among participants with VS at INSTI initiation, 51% sustained VS through a median of 11.0 months of follow-up; of the 49% with transient viremia, 77% later achieved VS again. There were no safety concerns associated with the use of INSTIs. CONCLUSIONS: More than half of treatment-experienced children, adolescents and young adults with detectable viremia at INSTI initiation did not achieve VS, while half of those with prior VS experienced transient viremia. Further evaluation of long-term outcomes associated with INSTI use among children, adolescents and young adults is warranted.

Digital Gaming to Improve Adherence Among Adolescents and Young Adults Living With HIV: Mixed-Methods Study to Test Feasibility and Acceptability.

BACKGROUND: An estimated 50% of adolescents and young adults (AYA) living with HIV are failing to adhere to prescribed antiretroviral treatment (ART). Digital games are effective in chronic disease management; however, research on gaming to improve ART adherence among AYA is limited. OBJECTIVE: We assessed the feasibility and acceptability of video gaming to improve AYA ART adherence. METHODS: Focus group discussions and surveys were administered to health care providers and AYA aged 13 to 24 years living with HIV at a pediatric HIV program in Washington, DC. During focus group discussions, AYA viewed demonstrations of 3 game prototypes linked to portable Wisepill medication dispensers. Content analysis strategies and thematic coding were used to identify adherence themes and gaming acceptance and feasibility. Likert scale and descriptive statistics were used to summarize response frequencies. RESULTS: Providers (n=10) identified common adherence barriers and strategies, including use of gaming analogies to improve AYA ART adherence. Providers supported exploration of digital gaming as an adherence intervention. In 6 focus group discussions, 12 AYA participants identified disclosure of HIV status and irregular daily schedules as major barriers to ART and use of alarms and pillboxes as reminders. Most AYA were very or somewhat likely to use the demonstrated game prototypes to help with ART adherence and desired challenging, individually tailored, user-friendly games with in-game incentives. Game prototypes were modified accordingly. CONCLUSIONS: AYA and their providers supported the use of digital games for ART adherence support. Individualization and in-game incentives were preferable and informed the design of an interactive technology-based adherence intervention among AYA living with HIV.
