Multisystem Inflammatory Syndrome in Children associated with COVID-19 infection attracted attention because some features overlapped with Kawasaki disease. And due to these overlapping features with Kawasaki disease, it has become difficult to diagnose both disorders. Therefore, this study focused on the differences between the patients diagnosed with MIS-C after COVID-19 and Kawasaki patients analyzed, particularly during the pre-pandemic period. In this way, it is aimed to reduce the dilemmas experienced in Diagnosis. In this descriptive study, 98 patients diagnosed with MIS-C throughout the pandemic were compared to 37 patients diagnosed with Kawasaki Disease during the pre-pandemic period.The patients in the MIS-C group were older children and clinically suffered from more headaches, vomiting, diarrhea, abdominal pain, and chest pain than Kawasaki patients. Signs of shock such as hypotension and tachycardia were more remarkable. Also, myocarditis and mitral regurgitation were detected at a higher rate in the MIS-C group. Besides, in the laboratory, lymphopenia, hypoalbuminemia, and creatinine elevation were more apparent.In conclusion, our present study findings support that although the MIS-C and Kawasaki share common features, they present with different clinical and laboratory features. And these differences are thought to be supportive in treatment and patient management.
