Multisystem inflammatory syndrome in adults (MIS-A) is a life-threatening disease that can develop weeks after coronavirus disease 2019 (COVID-19). MIS-A symptoms include multiorgan involvement, especially gastrointestinal tract and heart involvement, and Kawasaki disease-like symptoms. We herein report a 44-year-old Japanese man with MIS-A who had contracted COVID-19 five weeks ago and went into shock after acute gastroenteritis, acute kidney injury, and Kawasaki disease-like symptoms. Methylprednisone pulse and high-dose intravenous immunoglobulin resulted in recovery of shock and his renal function, but diffuse ST-segment elevation on electrocardiography and pericardial effusion with a fever emerged after therapy. Additional granulocyte-monocyte adsorptive apheresis successfully ameliorated the cardiac involvement.
