    (Wolters Kluwer, 2018-01-01) Lally, Michelle A.; van den Berg, Jacob J.; Westfall, Andrew O.; Rudy, Bret J.; Hosek, Sybil G.; Fortenberry, J. Dennis; Monte, Dina; Tanney, Mary R.; McFarland, Elizabeth J.; Xu, Jiahong; Kapogiannis, Bill G.; Wilson, Craig M.; Pediatrics, School of Medicine
    BACKGROUND: Beneficial HIV treatment outcomes require success at multiple steps along the HIV Continuum of Care. Youth living with HIV are a key population, and sites in the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) are known for modeling optimum HIV adolescent care. METHODS: A longitudinal cohort study conducted at 14 network sites across the United States assessed how the later steps of the Continuum of Care were achieved among the youth: engagement, treatment, and viral load (VL) suppression. Youth aged 13-24 who were behaviorally infected with HIV and linked to care at an ATN-affiliated site were eligible to participate. RESULTS: A total of 467 youth were enrolled and had 1 year of available data. Most were aged 22-24 (57%), male (79%), and black/non-Hispanic (71%). Most used alcohol (81%) and marijuana (61%) in the 3 months before enrollment, and 40% had a history of incarceration. Among this cohort of youth, 86% met criteria for care engagement; among these, 98% were prescribed antiretroviral therapy and 89% achieved VL suppression. Sustained VL suppression at all measured time points was found among 59% with initial suppression. Site characteristics were notable for the prevalence of adherence counseling (100%), case management (100%), clinic-based mental health (93%), and substance use (64%) treatment. CONCLUSIONS: Youth living with HIV in the United States can be successfully treated at health care sites with experience, excellence, and important resources and services. Sustained VL suppression may be an important step to add to the Continuum of Care for youth.

    Transmission Risk among Youth Living with HIV in the United States
    (Elsevier, 2020-07) van den Berg, Jacob J.; Gamarel, Kristi E.; Westfall, Andrew O.; Fortenberry, J. Dennis; Hosek, Sybil G.; Wilson, Craig M.; Lally, Michelle A.; Medicine, School of Medicine
    Purpose: HIV treatment as prevention is effective for reducing the risk of HIV transmission and the messaging campaign, undetectable = untransmittable, is gaining recognition. As youth living with HIV (YLWH) who have condomless sex may acquire and potentially transmit other sexually transmitted infections (STIs), the purpose of this study was to assess potential differences in transmission risk of HIV and other STIs among YLWH to inform subsequent HIV and STI prevention efforts. Methods: A cohort of 600 HIV behaviorally infected youth aged 13-24 years who were engaged in medical care completed an audio computer-assisted self-interview including questions about demographics, HIV disclosure, mental health, substance use, and sexual behaviors and beliefs. HIV viral loads and the presence of other STIs were abstracted from medical records. A viral load <200 copies/mL was considered undetectable. Univariate and bivariate analyses were conducted to examine differences by viral load and STIs. Results: Participants were categorized into four groups: (1) undetectable without STIs (55.2%); (2) undetectable with STIs (14.2%); (3) detectable without STIs (22.8%); and (4) detectable with STIs (7.8%). In comparison to the other three groups, youth in the undetectable group with STIs reported more favorable sexual risk reduction attitudes and beliefs, internet use for finding sex partners, anal sex with male partners, and condomless anal sex with male partners. Conclusions: YLWH with undetectable viral loads and other STIs engaged in higher risk behaviors. To realize the promise of the messaging campaign, undetectable = untransmittable, efforts must focus on sustained viral suppression and prevention of STIs among YLWH.
