A four-time-recurring typical complete Kawasaki syndrome successfully treated with intravenous immunoglobulin: A case report with literature review

摘要

Kawasaki syndrome (KS) typically strikes children younger than age 5 and presents with persistent high fever for at least 5 days combined with a heterogeneous polymorphous rash, extremity abnormalities, oropharyngitis, non-exudative conjunctivitis and cervical lymphadenitis. Treatment with high-dose intravenous immunoglobulin reduces substantially the risk of potential cardiovascular complications. For the first time, we report a child presenting all the clinical symptoms of KS, which recurred for 4 times in a period of 33 months. Each relapse was characterized by obstinate high fever combined with mucocutaneous signs and was each time successfully treated with intravenous immunoglobulin without the occurrence of any cardiovascular damage.
