[Bucillamin induced lung injury in rheumatoid arthritis].
Thirteen cases with rheumatoid arthritis who experienced lung injury during the treatment with bucillamine (Bc), about whom the questionnaires were answered by the physicians and whose X-ray films could be rechecked, were studied. Nine cases out of the 13 showed patchy mottled infiltrates in the bilateral center sparing the periphery, and the other 4 showed diffuse infiltrates. In these 9, serum gamma-globulin level decreased when lung injury appeared. The gamma-globulin level before the start of Bc administration, the level when lung injury appeared, the gamma-globulin decrease, and its ratio to the level before Bc were 1790 +/- 661 mg/dl, 1297 +/- 666 mg/dl, 459 +/- 320 mg/dl and 29.1 +/- 18.0%, respectively. In 5 out of the 9, gamma-globulin level reincreased when they recovered from the injury: 2 out of the 5 showed the reincrease even after steroid therapy. The data were obtained only from 2 out of the 4 with diffuse pattern in X-ray, and the decrease and the decrease ratio were 200 mg/dl (5.8%) in 1, and 49 mg/dl (3.6%) in the other. The characteristics of Bc-induced lung injury might be mottled infiltrates in the center appearing concurrently with serum immunoglobulin decrease.
