[Diseases associated with tuberculosis]

The characteristics of the immunological picture give some concepts and judgement elements about the combined diseases. On this subject, the significant index of higher tuberculosis incidence in patients with silicosis is paradigmatic. Furthermore chronic dismetabolisms and gamma-globulins immunodeficiencies support tuberculosis developing. However this matter is still object of several studies, as in the case of the relationships between tuberculosis and sarcoidosis, but at any rate immunological research results essential.
