ABSTRACT
The COVID-19 outbreak sparked by SARS-CoV-2, begat significant rates of malady worldwide, where children with an abnormal post-COVID ailment called the Multisystem Inflammatory Syndrome (MIS-C), were reported by April 2020. Here we have reviewed the clinical characteristics of the pediatric patients and the prognosis currently being utilized. A vivid comparison of MIS-C with other clinical conditions has been done. We have addressed the probable etiology and fundamental machinery of the inflammatory reactions, which drive organ failure. The involvement of androgen receptors portrays the likelihood of asymptomatic illness in children below adolescence, contributing to the concept of antibody-dependent enhancement.
ABSTRACT
Multisystem inflammatory syndrome in children (MIS-C) can cause a myriad of cardiac manifestations, including coronary dilation and aneurysms; giant aneurysms are infrequent. We describe 3patients with giant coronary aneurysms associated with MIS-C, including the youngest case reported to date, treated with intravenous immunoglobulin, corticosteroids, and biologic agents. (Level of Difficulty: Intermediate.).
ABSTRACT
A 4-year-old boy with multisystem inflammatory syndrome in children before widespread recognition of this disease developed complications, including coronary artery aneurysm, without anti-inflammatory treatment. With delayed treatment, all sequelae resolved. This case demonstrates a natural history supporting the role of anti-inflammatory treatment even with delayed or equivocal diagnosis. (Level of Difficulty: Intermediate.).
ABSTRACT
Multisystem inflammatory syndrome of children (MIS-C) continues to be a highly concerning diagnosis in those recently infected with SARS-CoV-2. The diagnosis of MIS-C cases will likely become even more challenging as vaccine uptake and natural immunity in previously infected persons leads to lower circulating rates of SARS-CoV-2 infection and will make cases sporadic. Febrile children presenting with cardiac dysfunction, symptoms overlapping Kawasaki disease or significant gastrointestinal complaints warrant a thorough screen in emergency departments, urgent care centers, and outpatient pediatric or family medicine practices. An increased index of suspicion and discussion regarding higher level of care (transferring to pediatric tertiary care centers or to intensive care) continues to be recommended. Herein we outline a broad approach with a multidisciplinary team for those meeting the case definition and believe such an approach is crucial for successful outcomes.
