    (AMA, 2021-02) Feldstein, Leora R.; Tenforde, Mark W.; Friedman, Kevin G.; Newhams, Margaret; Rose, Erica Billig; Dapul, Heda; Soma, Vijaya L.; Maddux, Aline B.; Mourani, Peter M.; Bowens, Cindy; Maamari, Mia; Hall, Mark W.; Riggs, Becky J.; Giuliano, John S.; Singh, Aalok R.; Li, Simon; Kong, Michele; Schuster, Jennifer E.; McLaughlin, Gwenn E.; Schwartz, Stephanie P.; Walker, Tracie C.; Loftis, Laura L.; Hobbs, Charlotte V.; Halasa, Natasha B.; Doymaz, Sule; Babbitt, Christopher J.; Hume, Janet R.; Gertz, Shira J.; Irby, Katherine; Clouser, Katharine N.; Cvijanovich, Natalie Z.; Bradford, Tamara T.; Smith, Lincoln S.; Heidemann, Sabrina M.; Zackai, Sheemon P.; Wellnitz, Kari; Nofziger, Ryan A.; Horwitz, Steven M.; Carroll, Ryan W.; Rowan, Courtney M.; Tarquinio, Keiko M.; Mack, Elizabeth H.; Fitzgerald, Julie C.; Coates, Bria M.; Jackson, Ashley M.; Young, Cameron C.; Son, Mary Beth F.; Patel, Manish M.; Newburger, Jane W.; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
    Importance Refinement of criteria for multisystem inflammatory syndrome in children (MIS-C) may inform efforts to improve health outcomes. Objective To compare clinical characteristics and outcomes of children and adolescents with MIS-C vs those with severe coronavirus disease 2019 (COVID-19). Setting, Design, and Participants Case series of 1116 patients aged younger than 21 years hospitalized between March 15 and October 31, 2020, at 66 US hospitals in 31 states. Final date of follow-up was January 5, 2021. Patients with MIS-C had fever, inflammation, multisystem involvement, and positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcriptase–polymerase chain reaction (RT-PCR) or antibody test results or recent exposure with no alternate diagnosis. Patients with COVID-19 had positive RT-PCR test results and severe organ system involvement. Exposure SARS-CoV-2. Main Outcomes and Measures Presenting symptoms, organ system complications, laboratory biomarkers, interventions, and clinical outcomes. Multivariable regression was used to compute adjusted risk ratios (aRRs) of factors associated with MIS-C vs COVID-19. Results Of 1116 patients (median age, 9.7 years; 45% female), 539 (48%) were diagnosed with MIS-C and 577 (52%) with COVID-19. Compared with patients with COVID-19, patients with MIS-C were more likely to be 6 to 12 years old (40.8% vs 19.4%; absolute risk difference [RD], 21.4% [95% CI, 16.1%-26.7%]; aRR, 1.51 [95% CI, 1.33-1.72] vs 0-5 years) and non-Hispanic Black (32.3% vs 21.5%; RD, 10.8% [95% CI, 5.6%-16.0%]; aRR, 1.43 [95% CI, 1.17-1.76] vs White). Compared with patients with COVID-19, patients with MIS-C were more likely to have cardiorespiratory involvement (56.0% vs 8.8%; RD, 47.2% [95% CI, 42.4%-52.0%]; aRR, 2.99 [95% CI, 2.55-3.50] vs respiratory involvement), cardiovascular without respiratory involvement (10.6% vs 2.9%; RD, 7.7% [95% CI, 4.7%-10.6%]; aRR, 2.49 [95% CI, 2.05-3.02] vs respiratory involvement), and mucocutaneous without cardiorespiratory involvement (7.1% vs 2.3%; RD, 4.8% [95% CI, 2.3%-7.3%]; aRR, 2.29 [95% CI, 1.84-2.85] vs respiratory involvement). Patients with MIS-C had higher neutrophil to lymphocyte ratio (median, 6.4 vs 2.7, P < .001), higher C-reactive protein level (median, 152 mg/L vs 33 mg/L; P < .001), and lower platelet count (<150 ×103 cells/μL [212/523 {41%} vs 84/486 {17%}, P < .001]). A total of 398 patients (73.8%) with MIS-C and 253 (43.8%) with COVID-19 were admitted to the intensive care unit, and 10 (1.9%) with MIS-C and 8 (1.4%) with COVID-19 died during hospitalization. Among patients with MIS-C with reduced left ventricular systolic function (172/503, 34.2%) and coronary artery aneurysm (57/424, 13.4%), an estimated 91.0% (95% CI, 86.0%-94.7%) and 79.1% (95% CI, 67.1%-89.1%), respectively, normalized within 30 days. Conclusions and Relevance This case series of patients with MIS-C and with COVID-19 identified patterns of clinical presentation and organ system involvement. These patterns may help differentiate between MIS-C and COVID-19.

    A Description of COVID-19-Directed Therapy in Children Admitted to US Intensive Care Units 2020
    (Oxford University Press, 2022) Schuster, Jennifer E.; Halasa, Natasha B.; Nakamura, Mari; Levy, Emily R.; Fitzgerald, Julie C.; Young, Cameron C.; Newhams, Margaret M.; Bourgeois, Florence; Staat, Mary A.; Hobbs, Charlotte V.; Dapul, Heda; Feldstein, Leora R.; Jackson, Ashley M.; Mack, Elizabeth H.; Walker, Tracie C.; Maddux, Aline B.; Spinella, Philip C.; Loftis, Laura L.; Kong, Michele; Rowan, Courtney M.; Bembea, Melania M.; McLaughlin, Gwenn E.; Hall, Mark W.; Babbitt, Christopher J.; Maamari, Mia; Zinter, Matt S.; Cvijanovich, Natalie Z.; Michelson, Kelly N.; Gertz, Shira J.; Carroll, Christopher L.; Thomas, Neal J.; Giuliano, John S., Jr.; Singh, Aalok R.; Hymes, Saul R.; Schwarz, Adam J.; McGuire, John K.; Nofziger, Ryan A.; Flori, Heidi R.; Clouser, Katharine N.; Wellnitz, Kari; Cullimore, Melissa L.; Hume, Janet R.; Patel, Manish; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
    Background: It is unclear how acute coronavirus disease 2019 (COVID-19)-directed therapies are used in children with life-threatening COVID-19 in US hospitals. We described characteristics of children hospitalized in the intensive care unit or step-down unit (ICU/SDU) who received COVID-19-directed therapies and the specific therapies administered. Methods: Between March 15, 2020 and December 27, 2020, children <18 years of age in the ICU/SDU with acute COVID-19 at 48 pediatric hospitals in the United States were identified. Demographics, laboratory values, and clinical course were compared in children who did and did not receive COVID-19-directed therapies. Trends in COVID-19-directed therapies over time were evaluated. Results: Of 424 children in the ICU/SDU, 235 (55%) received COVID-19-directed therapies. Children who received COVID-19-directed therapies were older than those who did not receive COVID-19-directed therapies (13.3 [5.6-16.2] vs 9.8 [0.65-15.9] years), more had underlying medical conditions (188 [80%] vs 104 [55%]; difference = 25% [95% CI: 16% to 34%]), more received respiratory support (206 [88%] vs 71 [38%]; difference = 50% [95% CI: 34% to 56%]), and more died (8 [3.4%] vs 0). Of the 235 children receiving COVID-19-directed therapies, 172 (73%) received systemic steroids and 150 (64%) received remdesivir, with rising remdesivir use over the study period (14% in March/April to 57% November/December). Conclusion: Despite the lack of pediatric data evaluating treatments for COVID-19 in critically ill children, more than half of children requiring intensive or high acuity care received COVID-19-directed therapies.

    Frequency, Characteristics and Complications of COVID-19 in Hospitalized Infants
    (Wolters Kluwer, 2022) Hobbs, Charlotte V.; Woodworth, Kate; Young, Cameron C.; Jackson, Ashley M.; Newhams, Margaret M.; Dapul, Heda; Maamari, Mia; Hall, Mark W.; Maddux, Aline B.; Sing, Aalok R.; Schuster, Jennifer E.; Rowan, Courtney M.; Fitzgerald, Julie C.; Irby, Katherine; Kong, Michele; Mack, Elizabeth H.; Staat, Mary A.; Cvijanovich, Natalie Z.; Bembea, Melania M.; Coates, Bria M.; Halasa, Natasha B.; Walker, Tracie C.; McLaughlin, Gwenn E.; Babbitt, Christopher J.; Nofziger, Ryan A.; Loftis, Laura L.; Bradford, Tamara T.; Campbell, Angela P.; Patel, Manish M.; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
    Background: Previous studies of severe acute respiratory syndrome coronavirus 2 infection in infants have incompletely characterized factors associated with severe illness or focused on infants born to mothers with coronavirus disease 2019 (COVID-19). Here we highlight demographics, clinical characteristics and laboratory values that differ between infants with and without severe acute COVID-19. Methods: Active surveillance was performed by the Overcoming COVID-19 network to identify children and adolescents with severe acute respiratory syndrome coronavirus 2-related illness hospitalized at 62 sites in 31 states from March 15 to December 27, 2020. We analyzed patients >7 days to <1 year old hospitalized with symptomatic acute COVID-19. Results: We report 232 infants >7 days to <1 year of age hospitalized with acute symptomatic COVID-19 from 37 US hospitals in our cohort from March 15 to December 27, 2020. Among 630 cases of severe COVID-19 in patients >7 days to <18 years old, 128 (20.3%) were infants. In infants with severe illness from the entire study period, the median age was 2 months, 66% were from racial and ethnic minority groups, 66% were previously healthy, 73% had respiratory complications, 13% received mechanical ventilation and <1% died. Conclusions: Infants accounted for over a fifth of children <18 years of age hospitalized for severe acute COVID-19, commonly manifesting with respiratory symptoms and complications. Although most infants hospitalized with COVID-19 did not suffer significant complications, longer term outcomes remain unclear. Notably, 75% of infants with severe disease were <6 months of age in this cohort study period, which predated maternal COVID-19 vaccination, underscoring the importance of maternal vaccination for COVID-19 in protecting the mother and infant.

    (American Heart Association, 2022) Dionne, Audrey; Friedman, Kevin G.; Young, Cameron C.; Newhams, Margaret M.; Kucukak, Suden; Jackson, Ashley M.; Fitzgerald, Julie C.; Smallcomb, Laura S.; Heidemann, Sabrina; McLaughlin, Gwenn E.; Irby, Katherine; Bradford, Tamara T.; Horwitz, Steven M.; Loftis, Laura L.; Soma, Vijaya L.; Rowan, Courtney M.; Kong, Michele; Halasa, Natasha B.; Tarquinio, Keiko M.; Schwarz, Adam J.; Hume, Janet R.; Gertz, Shira J.; Clouser, Katharine N.; Carroll, Christopher L.; Wellnitz, Kari; Cullimore, Melissa L.; Doymaz, Sule; Levy, Emily R.; Typpo, Katri V.; Lansell, Amanda N.; Butler, Andrew D.; Kuebler, Joseph D.; Zambrano, Laura D.; Campbell, Angela P.; Patel, Manish M.; Randolph, Adrienne G.; Newburger, Jane W.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
    Background: Cardiac complications related to COVID‐19 in children and adolescents include ventricular dysfunction, myocarditis, coronary artery aneurysm, and bradyarrhythmias, but tachyarrhythmias are less understood. The goal of this study was to evaluate the frequency, characteristics, and outcomes of children and adolescents experiencing tachyarrhythmias while hospitalized for acute severe COVID‐19 or multisystem inflammatory syndrome in children. Methods and Results: This study involved a case series of 63 patients with tachyarrhythmias reported in a public health surveillance registry of patients aged <21 years hospitalized from March 15, 2020, to December 31, 2021, at 63 US hospitals. Patients with tachyarrhythmias were compared with patients with severe COVID‐19–related complications without tachyarrhythmias. Tachyarrhythmias were reported in 22 of 1257 patients (1.8%) with acute COVID‐19 and 41 of 2343 (1.7%) patients with multisystem inflammatory syndrome in children. They included supraventricular tachycardia in 28 (44%), accelerated junctional rhythm in 9 (14%), and ventricular tachycardia in 38 (60%); >1 type was reported in 12 (19%). Registry patients with versus without tachyarrhythmia were older (median age, 15.4 [range, 10.4–17.4] versus 10.0 [range, 5.4–14.8] years) and had higher illness severity on hospital admission. Intervention for treatment of tachyarrhythmia was required in 37 (59%) patients and included antiarrhythmic medication (n=31, 49%), electrical cardioversion (n=11, 17%), cardiopulmonary resuscitation (n=8, 13%), and extracorporeal membrane oxygenation (n=9, 14%). Patients with tachyarrhythmias had longer hospital length of stay than those who did not, and 9 (14%) versus 77 (2%) died. Conclusions: Tachyarrhythmias were a rare complication of acute severe COVID‐19 and multisystem inflammatory syndrome in children and adolescents and were associated with worse clinical outcomes, highlighting the importance of close monitoring, aggressive treatment, and postdischarge care.
