Summary: In March 2020, children exposed to the virus that causes the COVID-19 illness, SARS-CoV-2, presented with fever and significant inflammation about a month after exposure to the virus. Some children were sick enough to require care in the intensive care unit for what came to be known as Multisystem Inflammatory Syndrome-Children (MIS-C).The clinical presentation shared many features with Kawasaki d...

Summary: The aim of the study is to make an accurate assessment of immune cells obtained from nasal mucosa and peripherial blood of MIS-C patients during the disease and the period of health.

Objectives: To perform systems immunology and strain diversity among SARS-CoV2 and MIS-C infected children. Study design: Cross sectional study. Study population: Children attending outpatients units and admitted in wards in pediatric hospitals in Chennai. Main study parameters/endpoints: Immune responses in children with SARS-CoV2 infection and multisystem inflammatory syndrome in children (MIS-C) infection ...

Summary: Multisystem inflammatory syndrome in children (MIS-C) is a rare severe complication to SARS-CoV-2 infection in children. It has been reported to occur in approximately one of 3,000 to 4,000 unvaccinated children during the COVID-19 waves dominated by variant Alpha of SARS-CoV-2. However, the incidences following SARS-CoV-2 infection with variant delta and omicron, as well as among vaccinated child...

Summary: This study seeks to explore immunological mechanisms in patients with Multisystem Inflammatory Syndrome in Children (MIS-C) to improve the understanding of this pathogenesis of this disease. In a cohort of MIS-C patients diagnosed during the Wild type, Alpha, Delta and Omicron waves, research samples will be analyzed for whole-blood RNA expression, proteomics, inflammatory cytokines, cellular immu...

Summary: Acute coronavirus disease 2019 (COVID-19) infection can include cardiac and pulmonary manifestations as well as post-infectious complications such as multisystem inflammatory syndrome (MIS-C), also known as pediatric inflammatory multisystem syndrome (PIMS / PIMS-TS). The precise etiology for COVID-19 symptoms and MIS-C is still obscure but there is evidence that endothelial damage may play a role...

Summary: This is a multisite prospective observational study to evaluate the clinical sequelae of symptomatic and asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the pediatric population, including coronavirus disease 2019 (COVID-19) and multisystem inflammatory syndrome in children (MIS-C), and characterize the immune response associated with these clinical presentat...

Summary: Beginning in mid-March 2020, pediatricians in communities in Western Europe, the UK, and the Eastern U.S. that had been severely affected by the Covid-19 pandemic noted an increased number of children presenting with fever and evidence of severe inflammation who required admission to intensive care. The syndrome was branded by the CDC in the U.S. as Multisystem Inflammatory Syndrome in Children (M...

Summary: The primary aim of this study is to evaluate the efficacy and safety of AT1001 versus placebo in pediatric patients with SARS-CoV-2 infection who experience early signs of MIS-C and are at high risk of progression. AT1001 10 μg/kg/dose up to 500 μg/dose (rounded to the nearest 50 μg) or matching placebo will be administered orally four times a day (QID) to the standard of care for MIS-C.
