[A case of interstitial pneumonia associated with dermatomyositis effectively treated with cyclosporin-A and cyclophosphamide pulse].
A 46-year-old male demonstrated edematous fingers on both hands in November 2003, and interstitial pneumonia was noted on chest X-ray during a medical check-up in December 2003. Since muscular weakness and fever developed thereafter, and interstitial pneumonia was aggravated on chest X-ray and CT, the patient was admitted to our hospital on March 25, 2004. Heliotrope-like erythema, and Gottron's sign were noted. Laboratory findings showed the following ; LDH 876 U/l ; CK 224 U/l ; CRP 5.68 mg/dl ; and KL-6 3270 U/ml. Autoantibodies such as anti-Jo-1 antibody were all negative. Chest X-ray and CT showed ground-glass opacity in the bilateral lower dorsal regions of the lung, and reduced volume of the inferior lobe. He was diagnosed as having dermatomyositis (DM) associated with progressive interstitial pneumonia. Although a combination of steroid pulse therapy and Cyclosporin-A were administered, the pulmonary lesions became aggravated. Additional intravenous Cyclophosphamide (IVCY) was initiated on the 6th hospital day, and interstitial pneumonia was markedly improved. Cases of progressive interstitial pneumonia associated with DM that are negative for anti-Jo-1 antibody and show a low ratio of CK/LDH are resistant to various treatments. Our case suggested that combination therapy with steroid, Cyclosporin-A, and IVCY is useful for the treatment of progressive interstitial pneumonia with DM.
