Factors Associated with Morbidity and Mortality Among Sexually Active Asian Adolescents and Young Adults with Perinatally Acquired HIV.

We assessed morbidity and mortality among Thai and Vietnamese adolescents and young adults with perinatally acquired human immunodeficiency virus (PHIV) compared with matched HIV-negative peers, 12-24 years of age. Data on serious adverse events (SAEs) were prospectively collected between 2013 and 2018 according to U.S. NIH Division of AIDS criteria. Of 288 youth, 142 had PHIV and 146 were HIV negative. At enrollment, the overall median age was 19 (interquartile range [IQR] 17-20) years, 67% were female, and 95% were Thai. Almost all PHIV youth (99%) were receiving antiretroviral therapy; 50% self-reported adherence ≥95%. Median CD4 was 579 (IQR 404-800) cells/mm, and 24% had HIV-RNA ≥1,000 copies/mL. During follow-up, 31 (22%) PHIV youth and 9 (6%) HIV-negative youth had at least one SAE. The overall crude SAE rate was 4.66 (3.42-6.35) per 100 person-years (PY); 7.22 (5.08-10.26) per 100 PY among youth with PHIV and 2.10 (1.09-4.03) per 100 PY in HIV-negative youth ( < .001). All seven deaths that occurred were among those with PHIV and primarily due to opportunistic infections (e.g., pneumocystis pneumonia, tuberculous meningitis). In multivariate analyses, having PHIV, being <20 years of age, and having anogenital high-risk human papillomavirus (HPV) infection with types 16 and/or 18 increased risk of SAEs. Among PHIV youth, CD4 count <350 cells/mm, HIV-RNA ≥1,000 copies/mL, advanced WHO stages, and having anogenital HPV 16 and/or 18 infection predicted higher incidence of SAEs; no prior use of alcohol was protective. These data emphasize the need for tailored interventions for adolescents with PHIV to prevent long-term morbidity and mortality.
