Abstract

This case is a 4-month-old patient with Kawasaki disease who showed coronary artery lesions after a disease relapse. Following the guidelines from the Randomised Controlled Trial to Assess Immunoglobulin plus Steroid Efficacy, the patient initially saw an improvement in symptoms. However, a relapse occurred despite low levels of C-reactive protein, leading to significant coronary artery growth. Treatment with a third dose of intravenous immunoglobulin and cyclosporine led to a slow reduction in the size of the coronary artery abnormalities. This case highlights the difficulty in monitoring Kawasaki disease progression through clinical symptoms and C-reactive protein levels alone. We also emphasise the necessity of echocardiographic monitoring in patients receiving anti-inflammatory treatments, including steroids, because coronary artery problems can arise or continue without the usual signs of Kawasaki disease or increased C-reactive protein levels.
