Advancing multidisciplinary management of pediatric hyperinflammatory disorders.

Area of Science:

• Pediatric Rheumatology and Immunology
• Infectious Disease Epidemiology
• Cardiology

Background:

• Pediatric hyperinflammatory diseases encompass Still's disease, Kawasaki disease (KD), multisystem inflammatory syndrome in children (MIS-C), and recurrent pericarditis (RP).
• These conditions share immune dysregulation and systemic inflammation, presenting diagnostic challenges due to overlapping symptoms.
• Timely differentiation is crucial to prevent severe complications like macrophage activation syndrome (MAS) and cardiac issues.

Purpose of the Study:

• To provide a comprehensive narrative review of the pathophysiology, diagnostic criteria, and management strategies for pediatric hyperinflammatory diseases.
• To emphasize the role of advanced biomarkers, imaging, and genetic testing in diagnosis and treatment.
• To highlight current and emerging therapeutic approaches for each condition.

Main Methods:

• Narrative review of existing literature on pediatric hyperinflammatory diseases.
• Exploration of pathophysiological mechanisms, clinical presentations, and diagnostic challenges.
• Synthesis of current management guidelines and therapeutic interventions, including biologics and immunomodulatory agents.

Main Results:

• Still's disease management benefits from IL-1 and IL-6 targeted biologics.
• Kawasaki disease (KD) treatment emphasizes timely IVIG and steroids for high-risk cases to prevent coronary aneurysms.
• MIS-C, linked to SARS-CoV-2, necessitates tailored immunomodulation for severe inflammation and multiorgan involvement.
• Recurrent pericarditis (RP) management focuses on NSAIDs, colchicine, and IL-1 inhibitors to minimize recurrence and steroid use.

Conclusions:

• A multidisciplinary approach with standardized diagnostic algorithms is essential for optimal care of pediatric inflammatory diseases.
• Future research should focus on predictive biomarkers, novel therapeutic targets, and evidence-based treatment protocols.
• Early and accurate diagnosis coupled with appropriate management significantly improves long-term outcomes.
