    (American Academy of Pediatrics, 2022) Maddux, Aline B.; Berbert, Laura; Young, Cameron C.; Feldstein, Leora R.; Zambrano, Laura D.; Kucukak, Suden; Newhams, Margaret M.; Miller, Kristen; FitzGerald, Madyson M.; He, Jie; Halasa, Natasha B.; Cvijanovich, Natalie Z.; Loftis, Laura L.; Walker, Tracie C.; Schwartz, Stephanie P.; Gertz, Shira J.; Tarquinio, Keiko M.; Fitzgerald, Julie C.; Kong, Michele; Schuster, Jennifer E.; Mack, Elizabeth H.; Hobbs, Charlotte V.; Rowan, Courtney M.; Staat, Mary A.; Zinter, Matt S.; Irby, Katherine; Crandall, Hillary; Flori, Heidi; Cullimore, Melissa L.; Nofziger, Ryan A.; Shein, Steven L.; Glas Gaspers, Mary; Hume, Janet R.; Levy, Emily R.; Chen, Sabrina R.; Patel, Manish M.; Tenforde, Mark W.; Weller, Edie; Campbell, Angela P.; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
    Objectives: To evaluate risk factors for postdischarge sequelae in children and adolescents hospitalized for acute coronavirus disease 2019 (COVID-19) or multisystem inflammatory syndrome in children (MIS-C). Methods: Multicenter prospective cohort study conducted in 25 United States pediatric hospitals. Patients <21-years-old, hospitalized May 2020 to May 2021 for acute COVID-19 or MIS-C with follow-up 2 to 4 months after admission. We assessed readmissions, persistent symptoms or activity impairment, and new morbidities. Multivariable regression was used to calculate adjusted risk ratios (aRR) and 95% confidence intervals (CI). Results: Of 358 eligible patients, 2 to 4 month survey data were available for 119 of 155 (76.8%) with acute COVID-19 and 160 of 203 (78.8%) with MIS-C. Thirteen (11%) patients with acute COVID-19 and 12 (8%) with MIS-C had a readmission. Thirty-two (26.9%) patients with acute COVID-19 had persistent symptoms (22.7%) or activity impairment (14.3%) and 48 (30.0%) with MIS-C had persistent symptoms (20.0%) or activity impairment (21.3%). For patients with acute COVID-19, persistent symptoms (aRR, 1.29 [95% CI, 1.04-1.59]) and activity impairment (aRR, 1.37 [95% CI, 1.06-1.78]) were associated with more organ systems involved. Patients with MIS-C and pre-existing respiratory conditions more frequently had persistent symptoms (aRR, 3.09 [95% CI, 1.55-6.14]) and those with obesity more frequently had activity impairment (aRR, 2.52 [95% CI, 1.35-4.69]). New morbidities were infrequent (9% COVID-19, 1% MIS-C). Conclusions: Over 1 in 4 children hospitalized with acute COVID-19 or MIS-C experienced persistent symptoms or activity impairment for at least 2 months. Patients with MIS-C and respiratory conditions or obesity are at higher risk of prolonged recovery.

    Investigating Health Disparities Associated With Multisystem Inflammatory Syndrome in Children After SARS-CoV-2 Infection
    (Wolters Kluwer, 2022) Zambrano, Laura D.; Ly, Kathleen N.; Link-Gelles, Ruth; Newhams, Margaret M.; Akande, Manzilat; Wu, Michael J.; Feldstein, Leora R.; Tarquinio, Keiko M.; Sahni, Leila C.; Riggs, Becky J.; Singh, Aalok R.; Fitzgerald, Julie C.; Schuster, Jennifer E.; Giuliano, John S., Jr.; Englund, Janet A.; Hume, Janet R.; Hall, Mark W.; Osborne, Christina M.; Doymaz, Sule; Rowan, Courtney M.; Babbitt, Christopher J.; Clouser, Katharine N.; Horwitz, Steven M.; Chou, Janet; Patel, Manish M.; Hobbs, Charlotte; Randolph, Adrienne G.; Campbell, Angela P.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
    Background: Multisystem inflammatory syndrome in children (MIS-C) is a postinfectious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related complication that has disproportionately affected racial/ethnic minority children. We conducted a pilot study to investigate risk factors for MIS-C aiming to understand MIS-C disparities. Methods: This case-control study included MIS-C cases and SARS-CoV-2-positive outpatient controls less than 18 years old frequency-matched 4:1 to cases by age group and site. Patients hospitalized with MIS-C were admitted between March 16 and October 2, 2020, across 17 pediatric hospitals. We evaluated race, ethnicity, social vulnerability index (SVI), insurance status, weight-for-age and underlying medical conditions as risk factors using mixed effects multivariable logistic regression. Results: We compared 241 MIS-C cases with 817 outpatient SARS-CoV-2-positive at-risk controls. Cases and controls had similar sex, age and U.S. census region distribution. MIS-C patients were more frequently previously healthy, non-Hispanic Black, residing in higher SVI areas, and in the 95th percentile or higher for weight-for-age. In the multivariable analysis, the likelihood of MIS-C was higher among non-Hispanic Black children [adjusted odds ratio (aOR): 2.07; 95% CI: 1.23-3.48]. Additionally, SVI in the 2nd and 3rd tertiles (aOR: 1.88; 95% CI: 1.18-2.97 and aOR: 2.03; 95% CI: 1.19-3.47, respectively) were independent factors along with being previously healthy (aOR: 1.64; 95% CI: 1.18-2.28). Conclusions: In this study, non-Hispanic Black children were more likely to develop MIS-C after adjustment for sociodemographic factors, underlying medical conditions, and weight-for-age. Investigation of the potential contribution of immunologic, environmental, and other factors is warranted.

    Risk factors for health impairments in children after hospitalization for acute COVID-19 or MIS-C
    (Frontiers Media, 2023-10-18) Maddux, Aline B.; Young, Cameron C.; Kucukak, Suden; Zambrano, Laura D.; Newhams, Margaret M.; Rollins, Caitlin K.; Halasa, Natasha B.; Gertz, Shira J.; Mack, Elizabeth H.; Schwartz, Stephanie; Kong, Michele; Loftis, Laura L.; Irby, Katherine; Rowan, Courtney M.; Tarquinio, Keiko M.; Zinter, Matt S.; Crandall, Hillary; Cvijanovich, Natalie Z.; Schuster, Jennifer E.; Fitzgerald, Julie C.; Staat, Mary A.; Hobbs, Charlotte V.; Nofziger, Ryan A.; Shein, Steven; Flori, Heidi; Cullimore, Melissa L.; Chatani, Brandon M.; Levy, Emily R.; Typpo, Katri V.; Hume, Janet R.; Campbell, Angela P.; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
    Objective: To identify risk factors for persistent impairments after pediatric hospitalization for acute coronavirus disease 2019 (COVID-19) or multisystem inflammatory syndrome in children (MIS-C) during the SARS-CoV-2 pandemic. Methods: Across 25 U.S. Overcoming COVID-19 Network hospitals, we conducted a prospective cohort study of patients <21-years-old hospitalized for acute COVID-19 or MIS-C (May 2020 to March 2022) surveyed 2- to 4-months post-admission. Multivariable regression was used to calculate adjusted risk ratios (aRR) and 95% confidence intervals (CI). Results: Of 232 children with acute COVID-19, 71 (30.6%) had persistent symptoms and 50 (21.6%) had activity impairments at follow-up; for MIS-C (n = 241), 56 (23.2%) had persistent symptoms and 58 (24.1%) had activity impairments. In adjusted analyses of patients with acute COVID-19, receipt of mechanical ventilation was associated with persistent symptoms [aRR 1.83 (95% CI: 1.07, 3.13)] whereas obesity [aRR 2.18 (95% CI: 1.05, 4.51)] and greater organ system involvement [aRR 1.35 (95% CI: 1.13, 1.61)] were associated with activity impairment. For patients with MIS-C, having a pre-existing respiratory condition was associated with persistent symptoms [aRR 3.04 (95% CI: 1.70, 5.41)] whereas obesity [aRR 1.86 (95% CI: 1.09, 3.15)] and greater organ system involvement [aRR 1.26 (1.00, 1.58)] were associated with activity impairments. Discussion: Among patients hospitalized, nearly one in three hospitalized with acute COVID-19 and one in four hospitalized with MIS-C had persistent impairments for ≥2 months post-hospitalization. Persistent impairments were associated with more severe illness and underlying health conditions, identifying populations to target for follow-up.

    Risk Factors for Multisystem Inflammatory Syndrome in Children: A Case-Control Investigation
    (Wolters Kluwer, 2023) Zambrano, Laura D.; Wu, Michael J.; Martin, Lora; Malloch, Lacy; Chen, Sabrina; Newhams, Margaret M.; Kucukak, Suden; Son, Mary Beth; Sanders, Cameron; Patterson, Kayla; Halasa, Natasha; Fitzgerald, Julie C.; Leroue, Matthew K.; Hall, Mark; Irby, Katherine; Rowan, Courtney M.; Wellnitz, Kari; Sahni, Leila C.; Loftis, Laura; Bradford, Tamara T.; Staat, Mary; Babbitt, Christopher; Carroll, Christopher L.; Pannaraj, Pia S.; Kong, Michele; Schuster, Jennifer E.; Chou, Janet; Patel, Manish M.; Randolph, Adrienne G.; Campbell, Angela P.; Hobbs, Charlotte V.; Overcoming COVID-19 investigators; Pediatrics, School of Medicine
    Background: In a 2020 pilot case-control study using medical records, we reported that non-Hispanic Black children were more likely to develop multisystem inflammatory syndrome in children (MIS-C) after adjustment for sociodemographic factors and underlying medical conditions. Using structured interviews, we investigated patient, household, and community factors underlying MIS-C likelihood. Methods: MIS-C case patients hospitalized in 2021 across 14 US pediatric hospitals were matched by age and site to outpatient controls testing positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within 3 months of the admission date. Caregiver interviews queried race/ethnicity, medical history, and household and potential community exposures 1 month before MIS-C hospitalization (case-patients) or after SARS-CoV-2 infection (controls). We calculated adjusted odds ratios (aOR) using mixed-effects multivariable logistic regression. Results: Among 275 case patients and 496 controls, race/ethnicity, social vulnerability and patient or family history of autoimmune/rheumatologic disease were not associated with MIS-C. In previously healthy children, MIS-C was associated with a history of hospitalization for an infection [aOR: 4.8; 95% confidence interval (CI): 2.1-11.0]. Household crowding (aOR: 1.7; 95% CI: 1.2-2.6), large event attendance (aOR: 1.7; 95% CI: 1.3-2.1), school attendance with limited masking (aOR: 2.6; 95% CI: 1.1-6.6), public transit use (aOR: 1.8; 95% CI: 1.4-2.4) and co-resident testing positive for SARS-CoV-2 (aOR: 2.2; 95% CI: 1.3-3.7) were associated with increased MIS-C likelihood, with risk increasing with the number of these factors. Conclusions: From caregiver interviews, we clarify household and community exposures associated with MIS-C; however, we did not confirm prior associations between sociodemographic factors and MIS-C.

    Variation in Early Anakinra Use and Short-Term Outcomes in Multisystem Inflammatory Syndrome in Children
    (Wiley, 2023) Chang, Joyce C.; Young, Cameron C.; Muscal, Eyal; Sexson Tejtel, Sara K.; Newhams, Margaret M.; Kucukak, Suden; Crandall, Hillary; Maddux, Aline B.; Rowan, Courtney M.; Halasa, Natasha B.; Harvey, Helen A.; Hobbs, Charlotte V.; Hall, Mark W.; Kong, Michele; Aguiar, Cassyanne L.; Schuster, Jennifer E.; Fitzgerald, Julie C.; Singh, Aalok R.; Wellnitz, Kari; Nofziger, Ryan A.; Cvijanovich, Natalie Z.; Mack, Elizabeth H.; Schwarz, Adam J.; Heidemann, Sabrina; Newburger, Jane W.; Zambrano, Laura D.; Campbell, Angela P.; Patel, Manish M.; Randolph, Adrienne G.; Son, Mary Beth F.; Overcoming COVID Investigators; Pediatrics, School of Medicine
    Objective: Evidence regarding effectiveness of interleukin-1 receptor antagonism in Multisystem Inflammatory Syndrome in Children (MIS-C) is lacking. We characterized variation in initial treatment with anakinra and evaluated cardiovascular outcomes associated with adding anakinra to standard initial therapy. Methods: We conducted a retrospective cohort study of MIS-C cases in a U.S. surveillance registry November 2020-December 2021. Day 0 was the first calendar day of immunomodulatory treatment. Factors associated with initial anakinra use (days 0–1) were identified. We compared cases ages 2–20 years receiving intravenous immunoglobulin (IVIG) and glucocorticoids vs. anakinra plus IVIG and/or glucocorticoids (days 0–1), using inverse probability weighting to balance severity. Primary outcomes were vasopressor requirement (day 3) and impaired left ventricular ejection fraction (days 3–4). The secondary outcome was 50% reduction in C-reactive protein (day 3). Results: Among 1516 MIS-C cases (44 sites), 193 (13%) received anakinra alone or with other immunomodulators as initial treatment (range 0–74% by site). Site accounted for 59% of residual variance in anakinra use. After balancing severity, initial treatment with anakinra plus IVIG and/or glucocorticoids (N=121) vs. IVIG and glucocorticoids (N=389) was not associated with significant differences in vasopressor requirement (25.6% vs. 20.1%; RR 1.27, 95% CI [0.88–1.84]), ventricular dysfunction (33.7% vs. 25.7%; RR 1.31, 95% CI [0.98–1.75]), or C-reactive protein reduction. Conclusions: We identified substantial variation in initial anakinra use in a real-world population of children with MIS-C, but no average short-term improvement in cardiovascular outcomes associated with early addition of anakinra to IVIG and/or glucocorticoids compared to IVIG and glucocorticoids alone.
