title: [Antibodies against mycobacterial antigens in patients with non-tuberculous pathology].
abstract: Antibodies (type IgG) against the A 60 antigen (Mycobacterium bovis, BCG) and an antigen of Mycobacterium tuberculosis were studied by ELISA in 79 patients with not tuberculous disease: 16 lung carcinoma, 16 hepatic cirrhosis and 47 patients with pulmonary disease. 59.5% and 50.6% of the patients showed antibodies against antigen A 60 and M. tuberculosis antigen respectively; more 25% were strongly positive against antigen A 60; in the patients with lung carcinoma this results were 62.5%. It is concluded than when this methods are use in the serologic diagnostic of tuberculosis the number of cirrhotic and not tuberculous pulmonary disease patients with antibodies against this antigens, obliges a careful study of the individual characteristics of each patient, and it is very important previously to discard a lung neoplastic pathology.
