Overview of pharmacological treatment of Kawasaki disease.
Kawasaki disease has been researched for 32 years but its aetiology is still unknown. Conventional therapy for the disease includes corticosteroids and aspirin (acetylsalicylic acid) as anti-inflammatory and/or antithrombotic agents but they have not been proven to prevent coronary artery aneurysms. Although a high incidence of liver dysfunction in Japanese patients with Kawasaki disease receiving high dose aspirin (> or =80 mg/kg/day) suggests racial differences in salicylate sensitivity, the duration of fever in patients receiving high dose aspirin is shorter than that in patients receiving moderate dosages (30 to 50 mg/kg/day). Furthermore, most corticosteroid-resistant patients were found to develop coronary artery aneurysms, many of which were large. With the clarification of the pathogenesis and clinical features of Kawasaki disease, advances in its treatment have been achieved. The introduction of high-dose intravenous gamma-globulin (IVGG) was an epoch in this field and IVGG is now a standard therapy with the incidence of persistent coronary aneurysms 1.9% in children with the disease receiving IVGG. Today, research is mainly directed toward the treatment of IVGG-resistant patients. One to 3 days of pulsed doses of methylprednisolone (30 mg/kg/day) or readministration of IVGG 1 g/kg (once to several times) has been recommended for patients with IVGG-resistant Kawasaki disease.[1]References
