Gammaglobulins at a dose of 400 mg/kg per day and acetylsalicylic acid are effective in preventing coronary artery aneurysms in Kawasaki disease.
Is it true that Gammaglobulins at a dose of 400 mg/kg per day and acetylsalicylic acid are effective in preventing coronary artery aneurysms in Kawasaki disease?
Partly. While traditional guidelines and older meta-analyses recommend combining gammaglobulins with aspirin for Kawasaki disease, recent randomized controlled trials and cohort studies question the added benefit of aspirin, showing that IVIG alone may be just as effective in preventing coronary artery complications.
Verdict: CONTESTED · 2 sources for, 2 against · Last checked
Although historical guidelines and older meta-analyses supported the combination of IVIG and acetylsalicylic acid (ASA), recent rigorous clinical trials (such as the RCT by Lin et al., 2025) and retrospective cohort studies (such as Maruo et al., 2024) have found that treatment without ASA is non-inferior or not associated with higher complication rates, creating a contested landscape regarding the necessity of aspirin.
