BNT162b2 mRNA Vaccination Against Coronavirus Disease 2019 is Associated With a Decreased Likelihood of Multisystem Inflammatory Syndrome in Children Aged 5-18 Years-United States, July 2021 - April 2022
(Oxford University Press, 2023) Zambrano, Laura D.; Newhams, Margaret M.; Olson, Samantha M.; Halasa, Natasha B.; Price, Ashley M.; Orzel, Amber O.; Young, Cameron C.; Boom, Julie A.; Sahni, Leila C.; Maddux, Aline B.; Bline, Katherine E.; Kamidani, Satoshi; Tarquinio, Keiko M.; Chiotos, Kathleen; Schuster, Jennifer E.; Cullimore, Melissa L.; Heidemann, Sabrina M.; Hobbs, Charlotte V.; Nofziger, Ryan A.; Pannaraj, Pia S.; Cameron, Melissa A.; Walker, Tracie C.; Schwartz, Stephanie P.; Michelson, Kelly N.; Coates, Bria M.; Flori, Heidi R.; Mack, Elizabeth H.; Smallcomb, Laura; Gertz, Shira J.; Bhumbra, Samina S.; Bradford, Tamara T.; Levy, Emily R.; Kong, Michele; Irby, Katherine; Cvijanovich, Natalie Z.; Zinter, Matt S.; Bowens, Cindy; Crandall, Hillary; Hume, Janet R.; Patel, Manish M.; Campbell, Angela P.; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
Background: Multisystem inflammatory syndrome in children (MIS-C), linked to antecedent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, is associated with considerable morbidity. Prevention of SARS-CoV-2 infection or coronavirus disease 2019 (COVID-19) by vaccination might also decrease MIS-C likelihood. Methods: In a multicenter, case-control, public health investigation of children ages 5-18 years hospitalized from 1 July 2021 to 7 April 2022, we compared the odds of being fully vaccinated (2 doses of BNT162b2 vaccine ≥28 days before hospital admission) between MIS-C case-patients and hospital-based controls who tested negative for SARS-CoV-2. These associations were examined by age group, timing of vaccination, and periods of Delta and Omicron variant predominance using multivariable logistic regression. Results: We compared 304 MIS-C case-patients (280 [92%] unvaccinated) with 502 controls (346 [69%] unvaccinated). MIS-C was associated with decreased likelihood of vaccination (adjusted OR [aOR]: .16; 95% CI: .10-.26), including among children ages 5-11 years (aOR: .22; 95% CI: .10-.52), ages 12-18 years (aOR: .10; 95% CI: .05-.19), and during the Delta (aOR: .06; 95% CI: .02-.15) and Omicron (aOR: .22; 95% CI: .11-.42) variant-predominant periods. This association persisted beyond 120 days after the second dose (aOR: .08; 95% CI: .03-.22) in 12-18-year-olds. Among all MIS-C case-patients, 187 (62%) required intensive care unit admission and 280 (92%) vaccine-eligible case-patients were unvaccinated. Conclusions: Vaccination with 2 doses of BNT162b2 is associated with reduced likelihood of MIS-C in children ages 5-18 years. Most vaccine-eligible hospitalized patients with MIS-C were unvaccinated.
BNT162b2 Protection against the Omicron Variant in Children and Adolescents
(Massachusetts Medical Society, 2022) Price, Ashley M.; Olson, Samantha M.; Newhams, Margaret M.; Halasa, Natasha B.; Boom, Julie A.; Sahni, Leila C.; Pannaraj, Pia S.; Irby, Katherine; Bline, Katherine E.; Maddux, Aline B.; Nofziger, Ryan A.; Cameron, Melissa A.; Walker, Tracie C.; Schwartz, Stephanie P.; Mack, Elizabeth H.; Smallcomb, Laura; Schuster, Jennifer E.; Hobbs, Charlotte V.; Kamidani, Satoshi; Tarquinio, Keiko M.; Bradford, Tamara T.; Levy, Emily R.; Chiotos, Kathleen; Bhumbra, Samina S.; Cvijanovich, Natalie Z.; Heidemann, Sabrina M.; Cullimore, Melissa L.; Gertz, Shira J.; Coates, Bria M.; Staat, Mary A.; Zinter, Matt S.; Kong, Michele; Chatani, Brandon M.; Hume, Janet R.; Typpo, Katri V.; Maamari, Mia; Flori, Heidi R.; Tenforde, Mark W.; Zambrano, Laura D.; Campbell, Angela P.; Patel, Manish M.; Randolph, Adrienne G.; Overcoming Covid-19 Investigators; Pediatrics, School of Medicine
Background: Spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.529 (omicron) variant, which led to increased U.S. hospitalizations for coronavirus disease 2019 (Covid-19), generated concern about immune evasion and the duration of protection from vaccines in children and adolescents. Methods: Using a case-control, test-negative design, we assessed vaccine effectiveness against laboratory-confirmed Covid-19 leading to hospitalization and against critical Covid-19 (i.e., leading to receipt of life support or to death). From July 1, 2021, to February 17, 2022, we enrolled case patients with Covid-19 and controls without Covid-19 at 31 hospitals in 23 states. We estimated vaccine effectiveness by comparing the odds of antecedent full vaccination (two doses of BNT162b2 messenger RNA vaccine) at least 14 days before illness among case patients and controls, according to time since vaccination for patients 12 to 18 years of age and in periods coinciding with circulation of B.1.617.2 (delta) (July 1, 2021, to December 18, 2021) and omicron (December 19, 2021, to February 17, 2022) among patients 5 to 11 and 12 to 18 years of age. Results: We enrolled 1185 case patients (1043 [88%] of whom were unvaccinated, 291 [25%] of whom received life support, and 14 of whom died) and 1627 controls. During the delta-predominant period, vaccine effectiveness against hospitalization for Covid-19 among adolescents 12 to 18 years of age was 93% (95% confidence interval [CI], 89 to 95) 2 to 22 weeks after vaccination and was 92% (95% CI, 80 to 97) at 23 to 44 weeks. Among adolescents 12 to 18 years of age (median interval since vaccination, 162 days) during the omicron-predominant period, vaccine effectiveness was 40% (95% CI, 9 to 60) against hospitalization for Covid-19, 79% (95% CI, 51 to 91) against critical Covid-19, and 20% (95% CI, -25 to 49) against noncritical Covid-19. During the omicron period, vaccine effectiveness against hospitalization among children 5 to 11 years of age was 68% (95% CI, 42 to 82; median interval since vaccination, 34 days). Conclusions: BNT162b2 vaccination reduced the risk of omicron-associated hospitalization by two thirds among children 5 to 11 years of age. Although two doses provided lower protection against omicron-associated hospitalization than against delta-associated hospitalization among adolescents 12 to 18 years of age, vaccination prevented critical illness caused by either variant.

(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.
Data-driven clustering identifies features distinguishing multisystem inflammatory syndrome from acute COVID-19 in children and adolescents
(Elsevier, 2021-08-31) Geva, Alon; Patel, Manish M.; Geva, Alon; Patel, Manish M.; Newhams, Margaret M.; Young, Cameron C.; Son, Mary Beth F.; Kong, Michele; Maddux, Aline B.; Hall, Mark W.; Riggs, Becky J.; Singh, Aalok R.; Giuliano, John S.; Hobbs, Charlotte V.; Loftis, Laura L.; McLaughlin, Gwenn E.; Schwartz, Stephanie P.; Schuster, Jennifer E.; Babbitt, Christopher J.; Halasa, Natasha B.; Gertz, Shira J.; Doymaz, Sule; Hume, Janet R.; Bradford, Tamara T.; Irby, Katherine; Carroll, Christopher L.; McGuire, John K.; Tarquinio, Keiko M.; Rowan, Courtney M.; Mack, Elizabeth H.; Cvijanovich, Natalie Z.; Fitzgerald, Julie C.; Spinella, Philip C.; Staat, Mary A.; Clouser, Katharine N.; Soma, Vijaya L.; Dapul, Heda; Maamari, Mia; Bowens, Cindy; Havlin, Kevin M.; Mourani, Peter M.; Heidemann, Sabrina M.; Horwitz, Steven M.; Feldstein, Leora R.; Tenforde, Mark W.; Newburger, Jane W.; Mandl, Kenneth D.; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
Background Multisystem inflammatory syndrome in children (MIS-C) consensus criteria were designed for maximal sensitivity and therefore capture patients with acute COVID-19 pneumonia. Methods We performed unsupervised clustering on data from 1,526 patients (684 labeled MIS-C by clinicians) <21 years old hospitalized with COVID-19-related illness admitted between 15 March 2020 and 31 December 2020. We compared prevalence of assigned MIS-C labels and clinical features among clusters, followed by recursive feature elimination to identify characteristics of potentially misclassified MIS-C-labeled patients. Findings Of 94 clinical features tested, 46 were retained for clustering. Cluster 1 patients (N = 498; 92% labeled MIS-C) were mostly previously healthy (71%), with mean age 7·2 ± 0·4 years, predominant cardiovascular (77%) and/or mucocutaneous (82%) involvement, high inflammatory biomarkers, and mostly SARS-CoV-2 PCR negative (60%). Cluster 2 patients (N = 445; 27% labeled MIS-C) frequently had pre-existing conditions (79%, with 39% respiratory), were similarly 7·4 ± 2·1 years old, and commonly had chest radiograph infiltrates (79%) and positive PCR testing (90%). Cluster 3 patients (N = 583; 19% labeled MIS-C) were younger (2·8 ± 2·0 y), PCR positive (86%), with less inflammation. Radiographic findings of pulmonary infiltrates and positive SARS-CoV-2 PCR accurately distinguished cluster 2 MIS-C labeled patients from cluster 1 patients. Interpretation Using a data driven, unsupervised approach, we identified features that cluster patients into a group with high likelihood of having MIS-C. Other features identified a cluster of patients more likely to have acute severe COVID-19 pulmonary disease, and patients in this cluster labeled by clinicians as MIS-C may be misclassified. These data driven phenotypes may help refine the diagnosis of MIS-C.
Effectiveness of BNT162b2 (Pfizer-BioNTech) mRNA Vaccination Against Multisystem Inflammatory Syndrome in Children Among Persons Aged 12–18 Years — United States, July–December 2021
(U.S. Department of Health & Human Services, 2022-01-14) Zambrano, Laura D.; Newhams, Margaret M.; Olson, Samantha M.; Halasa, Natasha B.; Price, Ashley M.; Boom, Julie A.; Sahni, Leila C.; Kamidani, Satoshi; Tarquinio, Keiko M.; Maddux, Aline B.; Heidemann, Sabrina M.; Bhumbra, Samina S.; Bline, Katherine E.; Nofziger, Ryan A.; Hobbs, Charlotte V.; Bradford, Tamara T.; Cvijanovich , Natalie Z.; Irby, Katherine; Mack, Elizabeth H.; Cullimore, Melissa L.; Pannaraj, Pia S.; Kong, Michele; Walker, Tracie C.; Gertz, Shira J.; Michelson, Kelly N.; Cameron, Melissa A.; Chiotos, Kathleen; Maamari, Mia; Schuster, Jennifer E.; Orzel, Amber O.; Patel, Manish M.; Campbell, Angela P.; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine

(Massachusetts Medical Society, 2022) Olson, Samantha M.; Newhams, Margaret M.; Halasa, Natasha B.; Price, Ashley M.; Boom, Julie A.; Sahni, Leila C.; Pannaraj, Pia S.; Irby, Katherine; Walker, Tracie C.; Schwartz, Stephanie P.; Maddux, Aline B.; Mack, Elizabeth H.; Bradford, Tamara T.; Schuster, Jennifer E.; Nofziger, Ryan A.; Cameron, Melissa A.; Chiotos, Kathleen; Cullimore, Melissa L.; Gertz, Shira J.; Levy, Emily R.; Kong, Michele; Cvijanovich, Natalie Z.; Staat, Mary A.; Kamidani, Satoshi; Chatani, Brandon M.; Bhumbra, Samina S.; Bline, Katherine E.; Gaspers, Mary G.; Hobbs, Charlotte V.; Heidemann, Sabrina M.; Maamari, Mia; Flori, Heidi R.; Hume, Janet R.; Zinter, Matt S.; Michelson, Kelly N.; Zambrano, Laura D.; Campbell, Angela P.; Patel, Manish M.; Randolph, Adrienne G.; Pediatrics, School of Medicine
Background: The increasing incidence of pediatric hospitalizations associated with coronavirus disease 2019 (Covid-19) caused by the B.1.617.2 (delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the United States has offered an opportunity to assess the real-world effectiveness of the BNT162b2 messenger RNA vaccine in adolescents between 12 and 18 years of age. Methods: We used a case-control, test-negative design to assess vaccine effectiveness against Covid-19 resulting in hospitalization, admission to an intensive care unit (ICU), the use of life-supporting interventions (mechanical ventilation, vasopressors, and extracorporeal membrane oxygenation), or death. Between July 1 and October 25, 2021, we screened admission logs for eligible case patients with laboratory-confirmed Covid-19 at 31 hospitals in 23 states. We estimated vaccine effectiveness by comparing the odds of antecedent full vaccination (two doses of BNT162b2) in case patients as compared with two hospital-based control groups: patients who had Covid-19-like symptoms but negative results on testing for SARS-CoV-2 (test-negative) and patients who did not have Covid-19-like symptoms (syndrome-negative). Results: A total of 445 case patients and 777 controls were enrolled. Overall, 17 case patients (4%) and 282 controls (36%) had been fully vaccinated. Of the case patients, 180 (40%) were admitted to the ICU, and 127 (29%) required life support; only 2 patients in the ICU had been fully vaccinated. The overall effectiveness of the BNT162b2 vaccine against hospitalization for Covid-19 was 94% (95% confidence interval [CI], 90 to 96); the effectiveness was 95% (95% CI, 91 to 97) among test-negative controls and 94% (95% CI, 89 to 96) among syndrome-negative controls. The effectiveness was 98% against ICU admission and 98% against Covid-19 resulting in the receipt of life support. All 7 deaths occurred in patients who were unvaccinated. Conclusions: Among hospitalized adolescent patients, two doses of the BNT162b2 vaccine were highly effective against Covid-19-related hospitalization and ICU admission or the receipt of life support.

Effectiveness of Maternal Vaccination with mRNA COVID-19 Vaccine During Pregnancy Against COVID-19–Associated Hospitalization in Infants Aged <6 Months — 17 States, July 2021–January 2022
(Center for Disease Control, 2022-02-18) Halasa, Natasha B.; Olson, Samantha M.; Staat, Mary A.; Newhams, Margaret M.; Price, Ashley M.; Boom, Julie A.; Sahni, Leila C.; Cameron, Melissa A.; Pannaraj, Pia S.; Bline, Katherine E.; Bhumbra, Samina S.; Bradford, Tamara T.; Chiotos, Kathleen; Coates, Bria M.; Cullimore, Melissa L.; Cvijanovich, Natalie Z.; Flori, Heidi R.; Gertz, Shira J.; Heidemann, Sabrina M.; Hobbs, Charlotte V.; Hume, Janet R.; Irby, Katherine; Kamidani, Satoshi; Kong, Michele; Levy, Emily R.; Mack, Elizabeth H.; Maddux, Aline B.; Michelson, Kelly N.; Nofziger, Ryan A.; Schuster, Jennifer E.; Schwartz, Stephanie P.; Smallcomb, Laura; Tarquinio, Keiko M.; Walker, Tracie C.; Zinter, Matt S.; Gilboa, Suzanne M.; Polen, Kara N.; Campbell, Angela P.; Randolph, Adrienne G.; Patel, Manish M.; Overcoming COVID-19 Investigators; Overcoming COVID-19 Network; Pediatrics, School of Medicine
COVID-19 vaccination is recommended for persons who are pregnant, breastfeeding, trying to get pregnant now, or who might become pregnant in the future, to protect them from COVID-19.§ Infants are at risk for life-threatening complications from COVID-19, including acute respiratory failure (1). Evidence from other vaccine-preventable diseases suggests that maternal immunization can provide protection to infants, especially during the high-risk first 6 months of life, through passive transplacental antibody transfer (2). Recent studies of COVID-19 vaccination during pregnancy suggest the possibility of transplacental transfer of SARS-CoV-2-specific antibodies that might provide protection to infants (3-5); however, no epidemiologic evidence currently exists for the protective benefits of maternal immunization during pregnancy against COVID-19 in infants. The Overcoming COVID-19 network conducted a test-negative, case-control study at 20 pediatric hospitals in 17 states during July 1, 2021-January 17, 2022, to assess effectiveness of maternal completion of a 2-dose primary mRNA COVID-19 vaccination series during pregnancy against COVID-19 hospitalization in infants. Among 379 hospitalized infants aged <6 months (176 with COVID-19 [case-infants] and 203 without COVID-19 [control-infants]), the median age was 2 months, 21% had at least one underlying medical condition, and 22% of case- and control-infants were born premature (<37 weeks gestation). Effectiveness of maternal vaccination during pregnancy against COVID-19 hospitalization in infants aged <6 months was 61% (95% CI = 31%-78%). Completion of a 2-dose mRNA COVID-19 vaccination series during pregnancy might help prevent COVID-19 hospitalization among infants aged <6 months.
Extracorporeal Membrane Oxygenation Characteristics and Outcomes in Children and Adolescents With COVID-19 or Multisystem Inflammatory Syndrome Admitted to U.S. ICUs
(Wolters Kluwer, 2023) Bembea, Melania M.; Loftis, Laura L.; Thiagarajan, Ravi R.; Young, Cameron C.; McCadden, Timothy P.; Newhams, Margaret M.; Kucukak, Suden; Mack, Elizabeth H.; Fitzgerald, Julie C.; Rowan, Courtney M.; Maddux, Aline B.; Kolmar, Amanda R.; Irby, Katherine; Heidemann, Sabrina; Schwartz, Stephanie P.; Kong, Michele; Crandall, Hillary; Havlin, Kevin M.; Singh, Aalok R.; Schuster, Jennifer E.; Hall, Mark W.; Wellnitz, Kari A.; Maamari, Mia; Gaspers, Mary G.; Nofziger, Ryan A.; Lim, Peter Paul C.; Carroll, Ryan W.; Munoz, Alvaro Coronado; Bradford, Tamara T.; Cullimore, Melissa L.; Halasa, Natasha B.; McLaughlin, Gwenn E.; Pannaraj, Pia S.; Cvijanovich, Natalie Z.; Zinter, Matt S.; Coates, Bria M.; Horwitz, Steven M.; Hobbs, Charlotte V.; Dapul, Heda; Graciano, Ana Lia; Butler, Andrew D.; Patel, Manish M.; Zambrano, Laura D.; Campbell, Angela P.; Randolph, Adrienne G.; Overcoming COVID-19 Investigators; Pediatrics, School of Medicine
Objectives: Extracorporeal membrane oxygenation (ECMO) has been used successfully to support adults with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related cardiac or respiratory failure refractory to conventional therapies. Comprehensive reports of children and adolescents with SARS-CoV-2-related ECMO support for conditions, including multisystem inflammatory syndrome in children (MIS-C) and acute COVID-19, are needed. Design: Case series of patients from the Overcoming COVID-19 public health surveillance registry. Setting: Sixty-three hospitals in 32 U.S. states reporting to the registry between March 15, 2020, and December 31, 2021. Patients: Patients less than 21 years admitted to the ICU meeting Centers for Disease Control criteria for MIS-C or acute COVID-19. Interventions: None. Measurements and main results: The final cohort included 2,733 patients with MIS-C ( n = 1,530; 37 [2.4%] requiring ECMO) or acute COVID-19 ( n = 1,203; 71 [5.9%] requiring ECMO). ECMO patients in both groups were older than those without ECMO support (MIS-C median 15.4 vs 9.9 yr; acute COVID-19 median 15.3 vs 13.6 yr). The body mass index percentile was similar in the MIS-C ECMO versus no ECMO groups (89.9 vs 85.8; p = 0.22) but higher in the COVID-19 ECMO versus no ECMO groups (98.3 vs 96.5; p = 0.03). Patients on ECMO with MIS-C versus COVID-19 were supported more often with venoarterial ECMO (92% vs 41%) for primary cardiac indications (87% vs 23%), had ECMO initiated earlier (median 1 vs 5 d from hospitalization), shorter ECMO courses (median 3.9 vs 14 d), shorter hospital length of stay (median 20 vs 52 d), lower in-hospital mortality (27% vs 37%), and less major morbidity at discharge in survivors (new tracheostomy, oxygen or mechanical ventilation need or neurologic deficit; 0% vs 11%, 0% vs 20%, and 8% vs 15%, respectively). Most patients with MIS-C requiring ECMO support (87%) were admitted during the pre-Delta (variant B.1.617.2) period, while most patients with acute COVID-19 requiring ECMO support (70%) were admitted during the Delta variant period. Conclusions: ECMO support for SARS-CoV-2-related critical illness was uncommon, but type, initiation, and duration of ECMO use in MIS-C and acute COVID-19 were markedly different. Like pre-pandemic pediatric ECMO cohorts, most patients survived to hospital discharge.
Factors Associated With COVID-19 Non-vaccination in Adolescents Hospitalized Without COVID-19
(Oxford University Press, 2023) Sahni, Leila C.; Price, Ashley M.; Olson, Samantha M.; Newhams, Margaret M.; Pannaraj, Pia S.; Maddux, Aline B.; Halasa, Natasha B.; Bline, Katherine E.; Cameron, Melissa A.; Schwartz, Stephanie P.; Walker, Tracie C.; Irby, Katherine; Chiotos, Kathleen; Nofziger, Ryan A.; Mack, Elizabeth H.; Smallcomb, Laura; Bradford, Tamara T.; Kamidani, Satoshi; Tarquinio, Keiko M.; Cvijanovich, Natalie Z.; Schuster, Jennifer E.; Bhumbra, Samina S.; Levy, Emily R.; Hobbs, Charlotte V.; Cullimore, Melissa L.; Coates, Bria M.; Heidemann, Sabrina M.; Gertz, Shira J.; Kong, Michele; Flori, Heidi R.; Staat, Mary A.; Zinter, Matt S.; Hume, Janet R.; Chatani, Brandon M.; Gaspers, Mary G.; Maamari, Mia; Randolph, Adrienne G.; Patel, Manish M.; Boom, Julie A.; Pediatrics, School of Medicine
Background: Pfizer-BioNTech COVID-19 vaccine received emergency use authorization for persons ≥ 16 years in December 2020 and for adolescents 12-15 years in May 2021. Despite the clear benefits and favorable safety profile, vaccine uptake in adolescents has been suboptimal. We sought to assess factors associated with COVID-19 non-vaccination in adolescents 12-18 years of age. Methods: Between June 1, 2021 and April 29, 2022, we assessed factors associated with COVID-19 non-vaccination in hospitalized adolescents ages 12-18 years enrolled in the Overcoming COVID-19 vaccine effectiveness network. Demographic characteristics and clinical information were captured through parent interviews and/or electronic medical record abstraction; COVID-19 vaccination was assessed through documented sources. We assessed associations between receipt of the COVID-19 vaccine and demographic and clinical factors using univariate and multivariable logistic regression and estimated adjusted odds ratios (aOR) for each factor associated with non-vaccination. Results: Among 1665 hospitalized adolescents without COVID-19, 56% were unvaccinated. Unvaccinated adolescents were younger (median age 15.1 years vs. 15.4 years, p < .01) and resided in areas with higher social vulnerability index (SVI) scores (median 0.6 vs 0.5, p < .001) than vaccinated adolescents. Residence in the Midwest [aOR 2.60 (95% CI: 1.80, 3.79)] or South [aOR 2.49 (95% CI: 1.77, 3.54)] US census regions, rarely or never receiving influenza vaccine [aOR 5.31 (95% CI: 3.81, 7.47)], and rarely or never taking precautions against COVID-19 [aOR 3.17 (95% CI: 1.94, 5.31)] were associated with non-vaccination against COVID-19. Conclusions: Efforts to increase COVID-19 vaccination of adolescents should focus on persons with geographic, socioeconomic, and medical risk factors associated with non-vaccination.
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.
