Abstract
A 76-year-old woman with rheumatoid arthritis who had been taking methotrexate (MTX) for 9 months was admitted because of acute respiratory failure. A chest radiograph revealed diffuse ground-glass attenuation. MTX-induced interstitial pneumonia (IP) was strongly suspected. Her respiratory failure worsened in spite of steroid pulse therapy. Intravenous administration of ulinastatin, however, dramatically improved her clinical condition. The second ulinastatin treatment was also effective. This case suggests that peripherally administered ulinastatin may be effective for steroid-resistant MTX-induced IP.
