Bucillamine [N-(2-mercapto-2-methylpropionyl)-L-cysteine] is an anti-rheumatic drug which was developed in Japan. Interstitial pneumonia induced by bucillamine has been reported in two patients with rheumatoid arthritis. In this report, we describe another patient who developed bucillamine-induced interstitial pneumonia. In August 1990, a 53-year-old man was admitted because of fever, dry cough and dyspnea on exertion (DOE). Five months previously, he had noted polyarthritis, and treatment with bucillamine was started in May 1990. His polyarthritis improved about 2.5 months after starting bucillamine, but he developed fever, dry cough, and DOE in August 1990. Chest X-ray on admission showed diffuse acinar and interstitial shadows predominantly in the bilateral upper lung fields. Pulmonary function tests revealed decreased vital capacity and diffusing capacity. Arterial blood gas (ABG) analysis revealed moderate hypoxemia with PaO2 67 Torr. After stopping bucillamine, the fever, dry cough, and DOE improved gradually, and the abnormal shadows on chest X-ray and ABG analysis showed moderate improvements. Bronchoalveolar lavage studies showed that total cell counts and proportion of lymphocytes were increased, and CD4+/CD8+ ratio of T cell subsets was decreased to 0.56. Transbronchial lung biopsy specimen revealed lymphocytic alveolitis and mild interstitial thickening. Lymphocyte stimulation test to bucillamine was negative, but patch test with bucillamine was positive. From the patient's clinical course, laboratory data, and pathologic findings, we concluded that this is a case of bucillamine-induced interstitial pneumonia. After treatment with corticosteroid, his chest X-ray and pulmonary function test showed marked improvements.(ABSTRACT TRUNCATED AT 250 WORDS)

We describe a patient with rheumatoid arthritis(RA) who developed bronchiolitis obliterans organizing pneumonia(BOOP) during the treatment of bucillamine. A 51 year-old man was admitted to the hospital for an abnormal shadow on his chest radiograph. He had been diagnosed as having RA 3 years previously and had been receiving 200 mg of bucillamine for 21 months. Two months prior to admission, he presented with a cough and his chest X-ray showed opacities in both lower lungs. He was treated with antibiotics for 2 months after the development of cough and lesions on the chest X-ray, but the symptoms and lung lesions became more aggravated. On admission, an HRCT revealed airspace consolidations in the subpleural space of both basal lungs and a CT-guided fine needle aspiration biopsy showed Masson's body filling air space, interstitial infiltration of acute and chronic inflammatory cells and type II cell hyperplasia, consistent with BOOP. Bucillamine was stopped and 50 mg of prednisolone was administered. His symptoms and infiltrations on the chest X-ray resolved. We suggest that bucillamine should be considered as a drug possibly associated with BOOP.
