582. Risk Factors for Progression to Hospitalization in Adolescents Presenting with Mild or Moderate COVID-19

Abstract

Background Most adolescents (age 12-17 years) with COVID-19 have mild disease. However, certain comorbidities may be risk factors for disease progression, and hospitalization rates for this age group have increased. Adolescents and adults with mild to moderate COVID-19 are eligible for monoclonal antibody therapy. To identify subgroups likely to benefit from this intervention, we evaluated the relationship between comorbidities and need for hospitalization in US adolescents presenting with mild to moderate COVID-19. Methods We analyzed presence of comorbidities and need for hospitalization within 28 days of diagnosis for adolescents in the PIDTRAN registry, a multicenter retrospective cohort of US pediatric patients with COVID-19. Comorbidities assessed included obesity, chronic kidney disease (CKD), diabetes (DM), immunosuppressive disease or treatment (IS), sickle cell disease (SCD), congenital/acquired heart disease (CHD), neurologic disease/neurodevelopmental disorders (ND), medical-related technology dependence (MTD), and pulmonary disease requiring daily inhaled corticosteroids (PD). We used multivariable logistic regression to determine race/ethnicity-adjusted associations between comorbidities and hospitalization. Results 1574 patients met inclusion criteria, of whom 180 (11.4%) were hospitalized within 28 days of COVID-19 diagnosis. In a race/ethnicity-adjusted model, the following comorbidities were independently associated with increased odds of hospitalization: IS (OR 10.8 [95%CI 5.4 – 21.7]); CKD (OR 5.1 [95%CI 1.0 – 25.6]); DM (OR 4.2 [95%CI 1.7 – 10.6]); SCD (OR 3.4 [95%CI 1.1 – 10.6]). ND (OR 3.0 [95%CI 1.7 – 5.4]); and obesity (OR 2.0 [95%CI 1.1 – 3.9]). Notably, CHD, MTD, and PD were not independently associated with hospitalization. There was no effect modification of race/ethnicity on the association between obesity or DM and hospitalization. Table 1: Characteristics of adolescents in our cohort Figure 1. Association between comorbidities and hospitalization. Model 1: comorbidities only. Model 2: comorbidities, adjusted for race/ethnicity. Abbreviations: CKD – chronic kidney disease; SCD – sickle cell disease; ICS – inhaled corticosteroids. Conclusion IS, CKD, DM, SCD, ND, and obesity were associated with increased odds of hospitalization in adolescents presenting with mild to moderate COVID-19. Adolescents with these comorbidities should be prioritized for consideration of treatment with monoclonal antibodies. Disclosures Gabriella S. Lamb, MD, MPH, Nothing to disclose

The association of sickle cell disorder with adverse outcomes in COVID‐19 patients: A meta‐analysis

“…One hundred and nine articles potentially eligible were assessed by reviewing the full texts. After discarding the meta-analysis, case reports, reviews, comments, articles with insufficient data or not published in English, and only on pregnant women, a total of 21 studies 14,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] satisfied the inclusion conditions and were selected in our metaanalysis. We drafted a flow chart that is fully consistent with the PRISMA guidelines (Figure 1).…”
