Rare refractory Kawasaki disease in an adolescent boy with cardiac and diffuse coronary artery involvement

Area of Science:

• Pediatric Rheumatology
• Cardiovascular Medicine
• Immunology

Background:

• Kawasaki disease is an acute, multisystemic vasculitis primarily affecting young children.
• While rare, it can occur in adolescents and adults, potentially leading to delayed diagnosis and coronary artery aneurysms.
• Refractory cases, resistant to standard treatments like intravenous immunoglobulin and aspirin, pose significant management challenges.

Observation:

• This report details a case of Kawasaki disease in an adolescent boy.
• The patient exhibited resistance to standard intravenous immunoglobulin and aspirin therapy.
• Severe cardiovascular damage was observed in the affected adolescent.

Findings:

• The case underscores the potential for severe cardiovascular complications in adolescents with Kawasaki disease.
• Treatment resistance in Kawasaki disease necessitates exploring alternative therapeutic strategies.
• Early recognition and aggressive management are crucial, even in atypical presentations.

Implications:

• This case highlights the need for increased awareness of Kawasaki disease in older age groups.
• Management protocols for refractory Kawasaki disease require further investigation and refinement.
• Prompt and effective treatment is vital to prevent long-term cardiovascular sequelae in affected individuals.
