Features of Intestinal Disease Associated With COVID-Related Multisystem Inflammatory Syndrome in Children

Area of Science:

• Pediatrics
• Infectious Diseases
• Gastroenterology

Background:

• Multisystem inflammatory syndrome in children (MIS-C) is a novel condition associated with SARS-CoV-2 infection.
• It presents with systemic inflammation and multi-organ dysfunction.

Purpose of the Study:

• To describe the clinical presentation and gastrointestinal manifestations of MIS-C.
• To highlight the spectrum of GI involvement and potential complications.

Main Methods:

• Retrospective review of pediatric cases diagnosed with MIS-C.
• Analysis of clinical symptoms, laboratory findings, imaging, and treatment outcomes, focusing on GI involvement.

Main Results:

• The majority of MIS-C patients exhibit significant gastrointestinal symptoms, including abdominal pain, diarrhea, and vomiting.
• Ileal and colonic inflammation are predominant, with potential for progressive bowel wall thickening, luminal narrowing, and obstruction.
• Most cases resolve with medical management, but rare instances necessitate surgical intervention.

Conclusions:

• Gastrointestinal involvement is a hallmark of MIS-C, ranging from mild symptoms to severe complications requiring surgery.
• Early recognition and management of GI manifestations are crucial for favorable outcomes in MIS-C patients.
