Unravel the Enigma of Kawasaki Disease: Groping in the Dark

Abstract

Kawasaki disease is one of the leading causes of acquired cardiac disease in childhood especially in Asian countries. Research efforts are extensive and focus on finding the molecular origin of Kawasaki disease. Kawasaki disease shows initially typical symptoms followed by coronary artery lesions in a few percentage of cases. Some patients develop coronary artery lesions, some do not. Research focus on finding biomarkers to predict the development of coronary artery lesions in a child with Kawasaki disease. Kawasaki-like features of the disease are known like MIS-C or Kawasaki-like syndrome, not clearly showing the classical clinical picture of Kawasaki disease. From that point, Kawasaki is not Kawasaki. This manuscript attempts to unravel the molecular and immunological enigma of a rare pediatric disease with to date, unknown etiology.
