ABSTRACT

We describe 2116 multisystem inflammatory syndrome in children (MIS-C) cases reported to the Centers for Disease Control and Prevention during Delta and Omicron circulation from July 2021 through January 2022. Half of MIS-C patients were aged 5-11 years, 52% received intensive care unit-level care, and 1.1% died. Only 3.0% of eligible patients were fully vaccinated prior to MIS-C onset.

ABSTRACT

BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) is a novel severe postinfectious condition associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The purpose of this report is to describe nationwide trends in the evolving clinical management of MIS-C. METHODS: Patients with MIS-C were reported from state and local jurisdictions to the Centers for Disease Control and Prevention's (CDC's) MIS-C national surveillance system. Patients' case reports were reviewed to ensure that they met the CDC MIS-C case definition and had sufficient data for analysis. The prevalence of use of treatments for MIS-C, temporal trends in use of these treatments, and frequency of administration of different treatment combinations were analyzed. RESULTS: There were 4470 patients meeting the MIS-C case definition with onset dates from 19 February 2020 to 31 July 2021. The proportion of patients admitted to an intensive care unit (ICU) has declined over time, from 78.7% in April 2020 to 57.5% in June 2021 (P = .001). The most common treatments were intravenous immunoglobulin (IVIG), given to 85.6% of patients; steroids (77.7%), and antiplatelet medications (73.7%); use of each of these treatments has increased over time, particularly in patients not requiring admission to an ICU (all P < .001). Older patients and non-Hispanic Black patients were more likely to receive additional modes of therapy including vasoactive medication, noninvasive respiratory support, anticoagulation medication, and intubation/mechanical ventilation. CONCLUSIONS: IVIG, steroids, and antiplatelet medication have become increasingly utilized as standard treatment for MIS-C patients, while the use of other treatments may be contingent on the type and severity of clinical findings.

ABSTRACT

BACKGROUND: Multisystem inflammatory syndrome in children (MIS-C) is a severe hyperinflammatory condition in persons aged <21 years associated with antecedent SARS-CoV-2 infection. Our objective was to describe MIS-C cases reported to CDC's national surveillance since the COVID-19 pandemic began. METHODS: We included patients meeting the MIS-C case definition with onset date from February 19, 2020 through July 31, 2021, using CDC's MIS-C case report form, which collects information on demographics, clinical presentation, and laboratory results. Trends over time across 3 MIS-C pandemic waves were assessed using Cochran-Armitage test for categorical and Jonckheere-Terpstra test for continuous variables. RESULTS: Of 4,901 reported cases, 4,470 met inclusion criteria. Median patient age increased over time (P<0.001), with a median of 9 years (interquartile range, 5-13 years) during the most recent (third) wave. Male predominance also increased (62% in third wave, P<0.001). A significant (P<0.001) increase in severe hematologic and gastrointestinal involvement was observed across the study period. Frequency of several cardiovascular complications (i.e., cardiac dysfunction, myocarditis, and shock/ vasopressor receipt) and renal failure declined (P<0.001). Provision of critical care including mechanical ventilation (P<0.001) and extracorporeal membrane oxygenation (ECMO; P=0.046) decreased, as did duration of hospitalization and mortality (each P<0.001). CONCLUSIONS: Over the first 3 pandemic waves of MIS-C in the United States, cardiovascular complications and clinical outcomes including length of hospitalization, receipt of ECMO, and death decreased over time. These data serve as a baseline for monitoring future trends associated with SARS-CoV-2 B.1.617.2 (Delta) or other variants and increased COVID-19 vaccination among children.

ABSTRACT

Multisystem inflammatory syndrome in children (MIS-C) occurs among persons aged <21 years following severe acute respiratory syndrome coronavirus 2 infection. Among 2818 MIS-C cases, 35 (1.2%) deaths were reported, primarily affecting racial/ethnic minority persons. Being 16-20 years old or having comorbidities was associated with death. Targeting coronavirus disease 2019 prevention among these groups and their caregivers might prevent MIS-C-related deaths.

ABSTRACT

Since February 12, 2020, approximately 6.5 million cases of SARS-CoV-2 infection, the cause of coronavirus disease 2019 (COVID-19), and 190,000 SARS-CoV-2-associated deaths have been reported in the United States (1,2). Symptoms associated with SARS-CoV-2 infection are milder in children compared with adults (3). Persons aged <21 years constitute 26% of the U.S. population (4), and this report describes characteristics of U.S. persons in that population who died in association with SARS-CoV-2 infection, as reported by public health jurisdictions. Among 121 SARS-CoV-2-associated deaths reported to CDC among persons aged <21 years in the United States during February 12-July 31, 2020, 63% occurred in males, 10% of decedents were aged <1 year, 20% were aged 1-9 years, 70% were aged 10-20 years, 45% were Hispanic persons, 29% were non-Hispanic Black (Black) persons, and 4% were non-Hispanic American Indian or Alaska Native (AI/AN) persons. Among these 121 decedents, 91 (75%) had an underlying medical condition,* 79 (65%) died after admission to a hospital, and 39 (32%) died at home or in the emergency department (ED).† These data show that nearly three quarters of SARS-CoV-2-associated deaths among infants, children, adolescents, and young adults have occurred in persons aged 10-20 years, with a disproportionate percentage among young adults aged 18-20 years and among Hispanics, Blacks, AI/ANs, and persons with underlying medical conditions. Careful monitoring of SARS-CoV-2 infections, deaths, and other severe outcomes among persons aged <21 years remains particularly important as schools reopen in the United States. Ongoing evaluation of effectiveness of prevention and control strategies will also be important to inform public health guidance for schools and parents and other caregivers.
