Pediatric Inflammatory Multisystem Syndrome: Time to Collaborate

Area of Science:

• Pediatric infectious diseases
• Immunology
• Public health

Background:

• The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been linked to a novel pediatric inflammatory condition.
• This syndrome, often termed pediatric inflammatory multisystem syndrome, presents with diverse clinical manifestations.
• Inconsistent nomenclature and case definitions complicate the understanding of its epidemiology and pathophysiology.

Purpose of the Study:

• To highlight the critical need for a unified definition and nomenclature for pediatric inflammatory multisystem syndrome associated with SARS-CoV-2.
• To underscore the challenges posed by current variability in research and clinical management.
• To advocate for international collaboration to establish a consensus.

Main Methods:

• This study is a review and analysis of existing literature and clinical reports.
• It examines the spectrum of reported cases and the different terminologies used.
• It synthesizes expert opinions on the defining characteristics of the syndrome.

Main Results:

• Significant heterogeneity exists in the naming conventions for this pediatric syndrome.
• Case definitions vary widely across different studies and geographic regions.
• This lack of standardization impedes comparative analysis and the development of evidence-based guidelines.

Conclusions:

• The current variability in the definition and naming of pediatric inflammatory multisystem syndrome associated with SARS-CoV-2 is a significant barrier.
• Establishing a consensus on terminology and case definitions is crucial for advancing scientific knowledge.
• Collaborative efforts are essential to improve the diagnosis, treatment, and outcomes for affected children.
