Insights

Multisystem inflammatory syndrome in children (MIS-C) linked to SARS-CoV-2 often presents with abdominal pain, shock, and rashes. Early diagnosis of MIS-C requires recognizing diverse clinical features and elevated inflammatory markers.

Area of Science:

  • Pediatric Infectious Diseases
  • Critical Care Medicine
  • Rheumatology

Background:

  • Multisystem inflammatory syndrome in children (MIS-C) is a rare but serious condition associated with SARS-CoV-2 infection.
  • Understanding the diverse clinical manifestations and laboratory findings of MIS-C is crucial for timely diagnosis and management.

Purpose of the Study:

  • To systematically identify and summarize the clinical manifestations and laboratory parameters of COVID-19-associated MIS-C.
  • To provide a comprehensive overview of the features of MIS-C to aid clinicians in diagnosis.

Main Methods:

  • A systematic literature search was conducted using Google Scholar, PubMed, and Cochrane Library.
  • Studies were selected based on keywords related to clinical characteristics and severity of MIS-C.
  • Clinical characteristics and laboratory parameters from eligible studies were analyzed.

Main Results:

  • A total of 44 studies involving 1840 patients with MIS-C were analyzed.
  • Common symptoms included abdominal pain (74%), shock (72%), vomiting (69%), diarrhea (62%), and rashes (60%).
  • Other significant findings were conjunctival infection (52%), myocarditis (49%), and Kawasaki disease-like presentations (44%).

Conclusions:

  • COVID-19-associated MIS-C presents with multisystem involvement and elevated inflammatory markers.
  • MIS-C can mimic Kawasaki disease, necessitating a high index of suspicion for diagnosis.
  • Early identification of clinical features and lab parameters is essential for prompt treatment of MIS-C.
