    Abstract:
    We have reported previously a first case of interstitial pneumonitis in rheumatoid arthritis treated with bucillamine in 1989. Thereafter, a dozen cases with lung injury associated with bucillamine therapy have been reported. To explore the similarities among these patients, we tried to carry out a survey concerning the lung injuries in these cases in the present study. We obtained the following results. (1) Patients with lung injury consisted of 7 females and 3 males, aged 65 years on average (59-72). (2) The total amount of bucillamine used was 20-40 g on average (5.1-144 g) during approximately 100 days. (3) Serum rheumatoid factor was positive in 9 of 10 cases. (4) HLA-DR4 was significantly (p less than 0.01) detected in all cases of lung injury associated with bucillamine. (5) Interestingly the effect of bucillamine on rheumatoid disease activity was excellent in most cases. (6) Drug lymphocyte stimulation test (DLST) using bucillamine was performed in 6 cases. Positive DLST was found in 3 of 6 cases. These results suggest that cell-mediated hypersensitivity reaction (Coombs & Gell type IV) may contribute to the development of lung injury associated with bucillamine therapy.
