[Kawasaki disease: an update]

Area of Science:

• Pediatrics
• Cardiology
• Infectious Diseases

Background:

• The etiology of Kawasaki disease (KD) is not fully understood, with infectious and genetic factors implicated.
• Recent American Heart Association guidelines (2017) emphasize improved diagnosis and risk stratification for KD.
• Identifying young children with incomplete KD is a key diagnostic challenge.

Purpose of the Study:

• To highlight updated diagnostic and treatment strategies for Kawasaki disease.
• To emphasize the importance of identifying high-risk patients, including those with incomplete KD.
• To discuss alternative therapies and monitoring protocols for KD complications.

Main Methods:

• Review of current literature and updated clinical guidelines for Kawasaki disease.
• Analysis of diagnostic criteria and risk assessment tools for KD.
• Evaluation of treatment options including intravenous immunoglobulin resistance and alternative therapies.
• Discussion of recommended cardiac assessment methods for KD patients with coronary aneurysms.

Main Results:

• Updated guidelines aim to improve the identification of at-risk individuals, particularly those with incomplete KD.
• TNF-alpha inhibitors are proposed as alternatives to corticosteroids for intravenous immunoglobulin-resistant cases.
• Regular myocardial perfusion assessment using various imaging modalities is recommended for patients with coronary aneurysms.

Conclusions:

• Early and accurate diagnosis of Kawasaki disease is critical, especially in young children.
• Management strategies are evolving to address treatment resistance and long-term cardiac complications.
• Comprehensive cardiac monitoring is essential for patients with KD-associated coronary artery abnormalities.
