Kawasaki Disease Shock Syndrome in the Eastern Region of Saudi Arabia: Case Series

Abstract

Kawasaki disease (KD) is a treatable medium-sized vasculitis in the pediatric population consisting of a myriad of specific signs and symptoms. A new entity of the disease, Kawasaki disease shock syndrome (KDSS), is defined as a KD patient presenting with signs of hypoperfusion. Our aim is to describe the signs and symptoms of KDSS and how it is treated and its consequences. Out of 37 patients diagnosed with KD in the period between January 2018 and December 2019 in hospitalized patients younger than 14 years of age at Maternity and Children's Hospital in Al-Hassa, Eastern Province, Saudi Arabia, 3 (8.10%) patients fulfilled the diagnostic criteria for KDSS: 2 (66%) were male and 1 (33%) was female. The cardinal feature in all of them was peripheral cardiovascular collapse. Two patients (66%) were found to have aseptic meningitis. All patients were treated with immunomodulatory agents (intravenous immunoglobulin) and all responded well to anti-inflammatory doses of aspirin. KDSS is the shock state of KD presenting with hypoperfusion symptoms, mainly irritability and changes in the level of consciousness and peripheral cardiovascular collapse. Awareness of such presentation and management by immunomodulatory medications helps in recovery and prevention of tragic consequences of such disease.
