Multisystem inflammatory syndrome in adult with features of Kawasaki disease

Abstract

Abstract We present a case of a 21‐year‐old woman with fever (>38.0°C) for 5 days, mucocutaneous lesions and refractory hypotension requiring dual inotropic support. The only significant past medical history was an episode of COVID infection 4 months before admission. She was diagnosed to have multisystem inflammatory syndrome in adult (MIS‐A)—a relatively new entity which occurs as a severe complication in patients post‐COVID‐19 infection. This condition can present remarkably similarly to Kawasaki disease. Although the paediatric counterpart of MIS‐A typically occurs within 2–6 weeks post COVID‐19 infection, MIS‐A may occur up to 4 months post‐COVID‐19 infection. We wish to raise awareness of this rare entity, their similarities with Kawasaki disease and the importance of early initiation of intravenous immunoglobulin and high‐dose aspirin.
