Recently, the annual reduction in the incidence rate of tuberculosis has slowed in Japan.One reason for this trend is believed to be due to an increase in the number of immunocompromised hosts. In our department, we discovered 10 cases of pulmonary tuberculosis among962 cases of collagenosis, and have analyzed the factors for the development of pulmonarytuberculosis in these patients. A total of 29 patients wer involved in the study: 22 withsystemic lupus erythematosus (SLE) (active disease, 10; inactive disease, 12) and having nopulmonary complications, and seven with pulmonary tuberculosis and no concomitantdiseases. Our findings were as follows: 1. Seven of the 10 patients with pulmonary tuberculosis also suffered from SLE. 2. Nine of the 10 patients had been treated with a corticosteroid or immunosuppressant. 3. Serum CHSO and erythrocyte sedimentation rate (ESR) were valuable indicaters fordiagnosing pulmonary tuberculosis in the patients with SLE. 4. Patients with SLE and pulmonary tuberculosis tended to show lymphopenia inperipheral blood, which was further enhanced by prolonged use of steroids. 5. Miliary tuberculosis rather than pulmonary tuberculosis tended to develop inelderly patients, and required longer hospitalization.
