[Kveim test performed with antigen obtained from lymph nodes]

This is our second paper about the Kveim test performed with G-77 antigen obtained from sarcoid lymph nodes. The antigen was tested in 46 patients with proved or suspected sarcoidosis and in 50 controls. Results were: 1) In 27 patients with active proved sarcoidosis and without treatment the test was positive in 85,1% (23/27 patients); 2) In 2/3 patients with proved sarcoidosis after therapeutic remission for more than two years and without treatment presently, the results were positive in one of them; 4) In 14 patients suspected to have sarcoidosis but showing lesions only on the skin the test was positive in 58,1% (8/14 patients); 5) In 48 controls the test was negative but in 2 it was positive. Our results agree with those of the literature.
