[Kawasaki disease and atherosclerosis]

Area of Science:

• Cardiovascular Science
• Pediatric Rheumatology
• Vascular Biology

Context:

• Kawasaki disease (KD) is a critical pediatric illness affecting coronary arteries.
• Endothelial damage persists even in the chronic stage of KD, impacting both coronary and systemic arteries.
• Previous studies indicate morphological and functional endothelial alterations in KD patients.

Purpose:

• To investigate the presence and extent of vascular endothelial dysfunction in KD patients during the chronic stage.
• To explore the potential link between a history of KD and an increased risk of early-onset atherosclerosis.

Summary:

• Morphological and functional studies confirm endothelial damage in coronary arteries (aneurysms and regressed aneurysms) during the chronic stage of Kawasaki disease (KD).
• Our findings reveal endothelial-dependent dilatation impairment in systemic arteries and pathological changes in KD-like allergic coronary arteritis models.
• These results suggest that vascular endothelial dysfunction extends to systemic arteries in chronic KD patients and may contribute to atherosclerosis development.

Impact:

• Highlights the long-term cardiovascular implications of Kawasaki disease beyond coronary arteries.
• Identifies potential risk factors for accelerated atherosclerosis in individuals with a history of KD.
• Emphasizes the need for continued monitoring and potential interventions for vascular health in KD survivors.
