Abstract
Background: Little is known about hospitalization in African adolescents with perinatally acquired HIV (PHIV+ adolescents). We described the incidence and causes of hospitalization in participants enrolled in the Cape Town Adolescent Antiretroviral Cohort in South Africa. Methods: Data collected from July 2013 to October 2018 from PHIV+ and HIV− adolescents were analyzed. Participants were assessed every 6 months and data on intercurrent hospitalization were abstracted. Causes of hospitalizations were classified according to ICD-10 codes. Descriptive statistics, time-to-event analysis and Poisson regression were used to describe causes and incidence and to determine incidence rate ratios for factors associated with hospitalization. Results: Five hundred fifteen PHIV+ and 109 HIV− participants had a median follow-up of 4.1 years [interquartile range (IQR): 3.7–4.6]. At enrollment HIV+ participants had a median duration of ART of 7.6 years (IQR: 4.6–9.2), median CD4 count of 713 cells/mm3 (IQR: 561.0–957.5) and 387 (75%) had a viral load <50 copies/mL. There were 149 hospital admissions over 64 months. Crude incidence rates for hospitalization were 6.6 [95% confidence interval (CI): 5.7–7.8] and 2.2 (95% CI: 1.2–4.3) per 100-person-years (P = <0.01) in HIV + and HIV−, respectively. Ninety of 149 (60%) admissions in HIV+ participants were classified as non-infectious, 36/149 (24%) were infectious and 23/149 (16%) were “other HIV-related” or “unknown.” Older age (15–19 years) and maintaining a CD4 >500 cells/cm3 were associated with decreased risk of hospitalization: adjusted incidence rate ratios of 0.61 (CI: 0.44–0.86, P = <0.01) and 0.68 (CI: 0.49–0.94, P = 0.02), respectively. Conclusions: PHIV+ adolescents had a high incidence of hospitalization despite ART. Strategies addressing infectious and non-infectious morbidity must be strengthened.
