Insights
Multisystem Inflammatory Syndrome in Children (MIS-C) can present severely in previously healthy youth after SARS-CoV-2 infection. Early recognition of MIS-C symptoms is crucial for timely emergency department intervention and treatment.
Area of Science:
- Pediatric Infectious Diseases
- Critical Care Medicine
- Public Health
Background:
- Initial COVID-19 reports in children indicated mild illness, primarily affecting infants and those with comorbidities.
- A shift occurred post-epidemic peak, with severe presentations emerging in previously healthy children aged 5-19.
- These severe cases often mimic toxic shock or Kawasaki disease, now termed Multisystem Inflammatory Syndrome in Children (MIS-C).
Observation:
- This case details an 11-year-old female with SARS-CoV-2 who presented twice to the Emergency Department.
- Initial symptoms included fever, rash, and pharyngitis.
- The second presentation revealed distributive shock, multi-organ injury, and systemic inflammation.
Findings:
- The patient developed fluid-refractory hypotension requiring vasopressors and Pediatric Intensive Care Unit (PICU) admission.
- Cardiac and renal dysfunction were noted during the second ED visit.
- The presentation was consistent with Multisystem Inflammatory Syndrome in Children (MIS-C) associated with COVID-19.
Implications:
- Disseminating information on severe and atypical COVID-19 presentations like MIS-C is vital for the medical community.
- Healthcare providers must be prepared to rapidly identify and manage MIS-C in pediatric emergency departments.
- Timely diagnosis and treatment can improve outcomes for children with severe inflammatory responses to SARS-CoV-2.
Abstract:
Early reports of COVID-19 in pediatric populations emphasized a mild course of disease with severe cases disproportionately affecting infant and comorbid pediatric patients. After the peak of the epidemic in New York City, in late April to early May, cases of severe illness associated with COVID-19 were reported among mostly previously healthy children ages 5-19. Many of these cases feature a toxic shock-like syndrome or Kawasaki-like syndrome in the setting of SARS-CoV-2 positive diagnostic testing and the CDC has termed this presentation Multisystem Inflammatory Syndrome (MIS-C). It is essential to disseminate information among the medical community regarding severe and atypical presentations of COVID-19 as prior knowledge can help communities with increasing caseloads prepare to quickly identify and treat these patients as they present in the emergency department. We describe a case of MIS-C in a child who presented to our Emergency Department (ED) twice and on the second visit was found to have signs of distributive shock, multi-organ injury and systemic inflammation associated with COVID-19. The case describes two ED visits by an 11- year-old SARS-CoV-2-positive female who initially presented with fever, rash and pharyngitis and returned within 48 hours with evidence of cardiac and renal dysfunction and fluid-refractory hypotension requiring vasopressors and PICU admission.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
