Current perspectives on Kawasaki disease

Area of Science:

• Pediatrics
• Rheumatology
• Infectious Diseases

Background:

• Kawasaki disease (KD) etiology remains elusive, with recent focus on coronavirus infection and genetic factors.
• Diagnostic criteria for KD have seen minor updates, including revised fever duration and new criteria for incomplete and atypical forms.
• Long-term outcomes and treatment strategies for KD, particularly for immunoglobulin-resistant cases, are areas of ongoing investigation.

Purpose of the Study:

• To review the current understanding of Kawasaki disease etiology and diagnostic criteria.
• To discuss treatment approaches for Kawasaki disease, including challenges in immunoglobulin-resistant cases.
• To highlight recent findings on long-term outcomes and potential risks like premature atherosclerosis.

Main Methods:

• Literature review of recent research on Kawasaki disease etiology.
• Analysis of updated diagnostic criteria, including echocardiography and laboratory findings.
• Summary of treatment modalities and outcomes for typical and resistant KD cases.

Main Results:

• Etiology of Kawasaki disease is still unknown, with emerging links to coronavirus and genetic polymorphisms.
• Updated diagnostic criteria now include specific criteria for incomplete Kawasaki disease.
• Long-term follow-up data reveal concerns about increased risk of premature atherosclerosis in childhood KD survivors with coronary abnormalities.

Conclusions:

• Kawasaki disease diagnosis and management continue to evolve, with ongoing research into its causes.
• Effective treatment strategies for immunoglobulin-resistant Kawasaki disease are crucial.
• Long-term surveillance for cardiovascular complications in Kawasaki disease patients is essential.
