Kawasaki-Syndrom bei einem 9-jährigen Jungen infolge von COVID-19

Since the beginning of 2020 an increase in a Kawasaki-like disease has been noted. The WHO assumes a connection to the COVID-19 pandemic and it is defined as the multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease 2019. A 9-year-old boy attended the pediatric emergency department with persistent fever and then developed a classical Kawasaki syndrome with affection of the left coronary artery. A specific origin of an infection could not be detected. The SARS-CoV-2 PCR was negative. In due course positive SARS-CoV‑2 antibodies were detected. The patient was treated with intravenous immunoglobulins, ASS and a glucocorticoid, which led to an improvement in the clinical and echocardiographic state of the patient.
