ABSTRACT
A 49-year-old man was hospitalized with a diagnosis of pneumonia and treated with antibiotics. His respiratory condition worsened after admission and he was intubated and put on a ventilator. He was diagnosed with anti-ARS antibody-positive interstitial pneumonia so he received steroid pulse therapy and cyclophosphamide pulse therapy. The hypoxemia worsened; he was then placed on extracorporeal membrane oxygenation (ECMO). Eventually, the pneumonia symptoms improved and ECMO and ventilator were withdrawn. Later, serum creatine kinase levels increased and muscle symptoms appeared during immunosuppressant dose reduction. This case indicates that ECMO is an effective way to support patients diagnosed with polymyositis-related interstitial pneumonia with acute respiratory failure.
