Acetylsalicylic acid for children with Kawasaki disease.

A 7-year-old child in my office was recently discharged from the hospital after receiving intravenous immunoglobulin for Kawasaki disease. Should I continue treatment with acetylsalicylic acid (ASA), and if so, what is the appropriate dose? The role of ASA for Kawasaki disease during the acute febrile phase has recently been called into question. According to several studies, ASA might reduce the duration of fever but it does not appear to directly reduce the incidence of coronary artery complications. However, with no high-quality randomized controlled trials, the evidence is scarce and more studies with good methodology are needed to determine the value of ASA in the treatment of Kawasaki disease. Currently, guidelines recommending the use of ASA should be followed.
