[Methylprednisolone-pulse therapy in a patient with rheumatoid arthritis and diffuse interstitial pneumonia/pulmonary fibrosis].
1990
: A forty-eight year-old female with rheumatoid arthritis developed cough, sputum and dyspnea. Chest X-ray film demonstrated bilateral diffuse interstitial pneumonia and pulmonary fibrosis. Laboratory findings were as follows: ESR 29 mm/h, CRP 3.86 mg/dl, RA test (+), RAHA (-) and WBC 7200/mm3. Marked hypoxemia (po(2)45 Torr) was demonstrated by blood gas analysis. Asymptomatic pulmonary fibrotic lesions which preceded articular symptoms were identified on her previous chest X-ray films. Methylprednisolone-pulse therapy (1g/day, for 3 days) was repeated three times with a 2-week interval. The treatment rapidly improved both pulmonary symptoms and chest X-ray findings. Although the fibrotic shadows on chest X-ray did not completely disappear, her conditions have been maintained well under the treatment with prednisolone (10mg/day) plus D-penicillamine (200mg/day).
