[The tuberculin test in intrathoracic sarcoidosis]
Objective:
To highlight the diagnosis and treatment of intrathoracic sarcoidosis.
Method:
The clinical and laboratory data of 35 cases of intrathoracic sarcoidosis in Tianjin thoracic hospital from 1991 to 1996 were reviewed. Tuberculin tests for 35 cases of sarcoidosis were carried out and the results were evaluated. Simultaneously, the results have been compared with that of literature published.
Result:
Of 35 cases of intrathoracic sarcoidosis 17 cases were tuberculin positive, 4 were strongly positive, positive tuberculin reactivity (60%) was significantly higher than that published.
Conclusion:
The results showed a considerably higher tuberculin positive rate, which may be due to the difference of positive tuberculin reactivity in different country or regions, age of patients and expression of gamma delta T cell receptor. The authors suggested that "sarcoidosis should be diagnosed with negative tuberculis reastivity" has to be reconsidered.
