Pediatr Infect Dis J 2023 42 (11) 990-998 BACKGROUND: Clinical management of multisystem inflammatory syndrome in children (MIS-C) has varied over time and by medical institution. METHODS: Data on patients with MIS-C were collected from 4 children's hospitals between March 16, 2020 and March 10, 2021. Relationships between MIS-C treatments and patient demographics, clinical characteristics, and outcomes were described. Propensity score matching was utilized to assess the relative risk of outcomes dependent on early treatment with intravenous immunoglobulin (IVIG) or low-dose steroids, controlling for potential confounding variables. RESULTS: Of 233 patients diagnosed with MIS-C, the most commonly administered treatments were steroids (88.4%), aspirin (81.1%), IVIG (77.7%) and anticoagulants (71.2%). Compared with those patients without respiratory features, patients with respiratory features were less likely to receive IVIG and steroids on the same day (combination treatment) (44.1%). Controlling for confounding variables, patients receiving IVIG within 1 day of hospitalization were less likely to have hospital length of stay ≥8 days (RR = 0.53, 95% CI: 0.31-0.88). Patients receiving low-dose steroids within 1 day of hospitalization were less likely to develop ventricular dysfunction (RR = 0.45, 95% CI: 0.26-0.77), have increasingly elevated troponin levels (RR = 0.55, 95% CI: 0.40-0.75) or have hospital length of stay ≥8 days (RR = 0.46, 95% CI: 0.29-0.74). CONCLUSION: Treatments for MIS-C differed by hospital, patient characteristics and illness severity. When IVIG and low-dose steroids were administered in combination or low-dose steroids were administered alone within 1 day of hospitalization, the risk of subsequent severe outcomes was decreased. |

Pediatr Infect Dis J 2024 BACKGROUND: The long-term effects of children hospitalized with multisystem inflammatory syndrome in children (MIS-C) or acute COVID-19 are not well known. Our objective was to determine long-term outcomes. METHODS: Children hospitalized with MIS-C or COVID-19 at 3 US hospitals from March 2020, through February 2021 were followed to assess health through 2 years post-hospitalization using medical records and patient surveys. RESULTS: Medical record abstraction was performed for 183 patients hospitalized with MIS-C, 53 of whom participated in surveys, and 97 patients hospitalized with COVID-19, 35 of whom participated in surveys. Patients with MIS-C were younger (median, 9 vs. 14 years of age for COVID-19 patients; P = 0.004), more frequently male (62% vs. 39%; P < 0.001) and had more cardiac (14% vs. 2%; P = 0.001) and neurologic sequelae (8% vs. 1%; P = 0.023). Children with COVID-19 more often had other comorbidities (59% vs. 19%; P < 0.001). Full mental recovery at the time of survey 2 (median, 16 months post-hospitalization for patients with MIS-C and 20 months for patients with COVID-19) was 85% and 88%, respectively; full physical recovery was 87% and 81%, respectively; and nearly all had resumption of normal activities. Patients with MIS-C reported more frequent headache at 1 month (45% vs. 20%; P = 0.037). Patients with COVID-19 were more likely to report cough at 1 month (37% vs. 17%; P = 0.045). Fatigue persisted >1 year in 15%-20% of patients in both groups. CONCLUSIONS: Approximately 20% of children with MIS-C and COVID-19 continued to have symptoms including fatigue and headache >1 year after hospital discharge. The duration of these findings emphasizes the importance of providers following patients until sequelae have resolved. |
Serologic Responses to COVID-19 Vaccination in Children with History of Multisystem Inflammatory Syndrome (MIS-C) (preprint)
Perez MA , Hsiao HM , Chen X , Kunkel A , Baida N , Hussaini L , Lu AT , Kao CM , Laham FR , Hunstad DA , Beltran Y , Hammett TA , Godfred-Cato S , Chahroudi A , Anderson EJ , Belay E , Rostad CA . medRxiv 2022 20 Understanding the serological responses to COVID-19 vaccination in children with history of MIS-C could inform vaccination recommendations. We prospectively enrolled five children hospitalized with MIS-C and measured SARS-CoV-2 binding IgG antibodies to spike protein variants longitudinally pre- and post-Pfizer-BioNTech BNT162b2 primary series COVID-19 vaccination. We found that SARS-CoV-2 variant cross-reactive IgG antibodies waned following acute MIS-C, but were significantly boosted with vaccination and maintained for at least 3 months. We then compared post-vaccination binding, pseudovirus neutralizing, and functional antibody-dependent cell-mediated cytotoxicity (ADCC) titers to the reference strain (Wuhan-hu-1) and Omicron variant (B.1.1.529) among previously healthy children (n=6) and children with history of MIS-C (n=5) or COVID-19 (n=5). Despite the breadth of binding antibodies elicited by vaccination in all three groups, pseudovirus neutralizing and ADCC titers were reduced to the Omicron variant. Vaccination after MIS-C or COVID-19 (hybrid immunity) conferred advantage in generating pseudovirus neutralizing and functional ADCC antibodies to Omicron.

Vaccine 2023 41 (17) 2743-2748 Understanding the serological responses to COVID-19 vaccination in children with history of MIS-C could inform vaccination recommendations. We prospectively enrolled seven children hospitalized with MIS-C and measured SARS-CoV-2 binding IgG antibodies to spike protein variants longitudinally pre- and post-Pfizer-BioNTech BNT162b2 primary series COVID-19 vaccination. We found that SARS-CoV-2 variant cross-reactive IgG antibodies variably waned following acute MIS-C, but were significantly boosted with vaccination and maintained for up to 3 months. We then compared post-vaccination binding, pseudovirus neutralizing, and functional antibody-dependent cell-mediated cytotoxicity (ADCC) titers to the reference strain (Wuhan-hu-1) and Omicron variant (B.1.1.529) among previously healthy children (n = 16) and children with history of MIS-C (n = 7) or COVID-19 (n = 8). Despite the breadth of binding antibodies elicited by vaccination in all three groups, pseudovirus neutralizing and ADCC titers were significantly reduced to the Omicron variant. |

Open Forum Infect Dis 2022 9 (3) ofac070 BACKGROUND: The serologic and cytokine responses of children hospitalized with multisystem inflammatory syndrome (MIS-C) vs coronavirus disease 2019 (COVID-19) are poorly understood. METHODS: We performed a prospective, multicenter, cross-sectional study of hospitalized children who met the Centers for Disease Control and Prevention case definition for MIS-C (n = 118), acute COVID-19 (n = 88), or contemporaneous healthy controls (n = 24). We measured severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike receptor-binding domain (RBD) immunoglobulin G (IgG) titers and cytokine concentrations in patients and performed multivariable analysis to determine cytokine signatures associated with MIS-C. We also measured nucleocapsid IgG and convalescent RBD IgG in subsets of patients. RESULTS: Children with MIS-C had significantly higher SARS-CoV-2 RBD IgG than children with acute COVID-19 (median, 2783 vs 146; P < .001), and titers correlated with nucleocapsid IgG. For patients with MIS-C, RBD IgG titers declined in convalescence (median, 2783 vs 1135; P = .010) in contrast to patients with COVID-19 (median, 146 vs 4795; P < .001). MIS-C was characterized by transient acute proinflammatory hypercytokinemia, including elevated levels of interleukin (IL) 6, IL-10, IL-17A, and interferon gamma (IFN-γ). Elevation of at least 3 of these cytokines was associated with significantly increased prevalence of prolonged hospitalization ≥8 days (prevalence ratio, 3.29 [95% CI, 1.17-9.23]). CONCLUSIONS: MIS-C was associated with high titers of SARS-CoV-2 RBD IgG antibodies and acute hypercytokinemia with IL-6, IL-10, IL-17A, and IFN-γ. |
