Diversity of Cardiac and Gastrointestinal Presentations of Multisystem Inflammatory Syndrome in Children (MIS-C)...

Area of Science:

• Pediatrics
• Infectious Diseases
• Critical Care Medicine

Background:

• COVID-19 is typically mild in children but can lead to severe outcomes.
• Multisystem Inflammatory Syndrome in Children (MIS-C) is a recognized post-COVID-19 hyperinflammatory condition.
• MIS-C presents with multi-organ involvement and can be life-threatening.

Purpose of the Study:

• To describe the clinical characteristics, treatment, and outcomes of children with MIS-C.
• To highlight the diverse presentations of MIS-C, including gastrointestinal symptoms and shock.
• To emphasize the importance of SARS-CoV-2 testing and cardiac monitoring in children with hyperinflammatory syndromes.

Main Methods:

• Retrospective case series of six children diagnosed with MIS-C.
• Clinical data collection including symptoms, laboratory findings, and treatment modalities.
• Analysis of patient outcomes following interventions.

Main Results:

• All six children had confirmed SARS-CoV-2 infection.
• Common symptoms included fever and weakness; four presented with gastrointestinal issues.
• Treatments included intravenous immunoglobulin, aspirin, and other agents based on clinical status.
• Median hospitalization was 7 days with rapid clinical improvement after treatment.

Conclusions:

• MIS-C can present with varied symptoms, including gastrointestinal distress and shock, mimicking other conditions.
• Prompt diagnosis and treatment of MIS-C are associated with favorable outcomes.
• Testing for SARS-CoV-2 and cardiac monitoring are recommended for children with unexplained hyperinflammatory conditions.
