    Community-Onset Bacterial Coinfection in Children Critically Ill With Severe Acute Respiratory Syndrome Coronavirus 2 Infection
    (Oxford University Press, 2023-03-06) Moffitt, Kristin L.; Nakamura, Mari M.; Young, Cameron C.; Newhams, Margaret M.; Halasa, Natasha B.; Reed, J. Nelson; Fitzgerald, Julie C.; Spinella, Philip C.; Soma, Vijaya L.; Walker, Tracie C.; Loftis, Laura L.; Maddux, Aline B.; Kong, Michele; Rowan, Courtney M.; Hobbs, Charlotte V.; Schuster, Jennifer E.; Riggs, Becky J.; McLaughlin, Gwenn E.; Michelson, Kelly N.; Hall, Mark W.; Babbitt, Christopher J.; Cvijanovich, Natalie Z.; Zinter, Matt S.; Maamari, Mia; Schwarz, Adam J.; Singh, Aalok R.; Flori, Heidi R.; Gertz, Shira J.; Staat, Mary A.; Giuliano, John S., Jr.; Hymes, Saul R.; Clouser, Katharine N.; McGuire, John; Carroll, Christopher L.; Thomas, Neal J.; Levy, Emily R.; Randolph, Adrienne G.; Pediatrics, School of Medicine
    Background: Community-onset bacterial coinfection in adults hospitalized with coronavirus disease 2019 (COVID-19) is reportedly uncommon, though empiric antibiotic use has been high. However, data regarding empiric antibiotic use and bacterial coinfection in children with critical illness from COVID-19 are scarce. Methods: We evaluated children and adolescents aged <19 years admitted to a pediatric intensive care or high-acuity unit for COVID-19 between March and December 2020. Based on qualifying microbiology results from the first 3 days of admission, we adjudicated whether patients had community-onset bacterial coinfection. We compared demographic and clinical characteristics of those who did and did not (1) receive antibiotics and (2) have bacterial coinfection early in admission. Using Poisson regression models, we assessed factors associated with these outcomes. Results: Of the 532 patients, 63.3% received empiric antibiotics, but only 7.1% had bacterial coinfection, and only 3.0% had respiratory bacterial coinfection. In multivariable analyses, empiric antibiotics were more likely to be prescribed for immunocompromised patients (adjusted relative risk [aRR], 1.34 [95% confidence interval {CI}, 1.01-1.79]), those requiring any respiratory support except mechanical ventilation (aRR, 1.41 [95% CI, 1.05-1.90]), or those requiring invasive mechanical ventilation (aRR, 1.83 [95% CI, 1.36-2.47]) (compared with no respiratory support). The presence of a pulmonary comorbidity other than asthma (aRR, 2.31 [95% CI, 1.15-4.62]) was associated with bacterial coinfection. Conclusions: Community-onset bacterial coinfection in children with critical COVID-19 is infrequent, but empiric antibiotics are commonly prescribed. These findings inform antimicrobial use and support rapid de-escalation when evaluation shows coinfection is unlikely.

    Life-Threatening Complications of Influenza vs Coronavirus Disease 2019 (COVID-19) in US Children
    (Oxford University Press, 2023) Halasa, Natasha B.; Spieker, Andrew J.; Young, Cameron C.; Olson, Samantha M.; Newhams, Margaret M.; Amarin, Justin Z.; Moffitt, Kristin L.; Nakamura, Mari M.; Levy, Emily R.; Soma, Vijaya L.; Talj, Rana; Weiss, Scott L.; Fitzgerald, Julie C.; Mack, Elizabeth H.; Maddux, Aline B.; Schuster, Jennifer E.; Coates, Bria M.; Hall, Mark W.; Schwartz, Stephanie P.; Schwarz, Adam J.; Kong, Michele; Spinella, Philip C.; Loftis, Laura L.; McLaughlin, Gwenn E.; Hobbs, Charlotte V.; Rowan, Courtney M.; Bembea, Melania M.; Nofziger, Ryan A.; Babbitt, Christopher J.; Bowens, Cindy; Flori, Heidi R.; Gertz, Shira J.; Zinter, Matt S.; Giuliano, John S.; Hume, Janet R.; Cvijanovich, Natalie Z.; Singh, Aalok R.; Crandall, Hillary A.; Thomas, Neal J.; Cullimore, Melissa L.; Patel, Manish M.; Randolph, Adrienne G.; Pediatric Intensive Care Influenza; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
    Background: Clinical differences between critical illness from influenza infection vs coronavirus disease 2019 (COVID-19) have not been well characterized in pediatric patients. Methods: We compared demographics, clinical characteristics, and outcomes of US children (aged 8 months to 17 years) admitted to the intensive care or high-acuity unit with influenza or COVID-19. Using mixed-effects models, we assessed the odds of death or requiring life support for influenza vs COVID-19 after adjustment for age, sex, race and Hispanic origin, and underlying conditions including obesity. Results: Children with influenza (n = 179) were younger than those with COVID-19 (n = 381; median, 5.2 years vs 13.8 years), less likely to be non-Hispanic Black (14.5% vs 27.6%) or Hispanic (24.0% vs 36.2%), and less likely to have ≥1 underlying condition (66.4% vs 78.5%) or be obese (21.4% vs 42.2%), and a shorter hospital stay (median, 5 days vs 7 days). They were similarly likely to require invasive mechanical ventilation (both 30.2%), vasopressor support (19.6% and 19.9%), or extracorporeal membrane oxygenation (2.2% and 2.9%). Four children with influenza (2.2%) and 11 children with COVID-19 (2.9%) died. The odds of death or requiring life support in children with influenza vs COVID-19 were similar (adjusted odds ratio, 1.30; 95% confidence interval, .78-2.15; P = .32). Conclusions: Despite differences in demographics and clinical characteristics of children with influenza or COVID-19, the frequency of life-threatening complications was similar. Our findings highlight the importance of implementing prevention measures to reduce transmission and disease severity of influenza and COVID-19.
