Objective: To probe into the clinical features and diagnostic basis of incomplete Kawasaki disease (IKD) with non-infectious diarrhea onset

and to provided early detection and treatment

reduce the cardiovascular system complications and improve the prognosis. Methods: Clinical data and laboratory results of 10 IKD children with non-infectious diarrhea onset in pediatrics of our hospital from Dec. 2016 to Jun. 2020 were retrospectively analyzed. Results: The main clinical manifestations of IKD with non-infectious diarrhea onset were repeated diarrhea

fever

conjunctival congestion

chapped lips

edema

anemia and perianal peeling. Laboratory examinations showed C-reactive protein

procalcitonin

serum amyloid protein

erythrocyte sedimentation rate and platelet increased significantly

and coronary artery disease could be seen by continuous monitoring of cardiac color Doppler echocardiography. Conclusion: The early clinical manifestations of IKD with non-infectious diarrhea onset are mainly repeated diarrhea and fever

with no positive results in stool and blood culture. Laboratory examinations shows that the inflammatory factors increase significantly. During hospitalization

the effect of anti-infection is not satisfied

color Doppler echocardiography should be performed as early as possible

clinical diagnosis of IKD should be confirmed as soon as possible

and early treatment should be carried out to reduce the occurrence of coronary artery disease.
