Measurement of levels of antibodies to a causative agent of tuberculosis with the aid of the enzyme immunoassay can serve as one of methods for early diagnosis of infectious- and dust diseases. Patients with clinically established diagnosis of dust bronchitis, latent silicotuberculosis and manifest silicotuberculosis demonstrated a significantly higher level of antituberculous antibodies in blood plasma as compared to controls. Establishment of the above fact permits regarding a major proportion of dust bronchitis as a silicotuberculous process.

CT yields valuable additional data in early silicotuberculosis, which makes it possible to follow the extent of a silicotuberculous process more completely, to make a better diagnosis of nodal and focal shadows, to identify small decay cavities in the foci and infiltrates. CT is the method of choice in following up patients with silicotuberculosis.

A total of 53 patients with initial and manifest forms of dust bronchitis underwent BAL. There has been found the following: a decrease in the mononuclear phagocyte system cells (MPhS) reflecting the state of local cellular immunity; rise in the amounts of coniophages, suggesting phagocytic activity of alveolar macrophages (AM) and dust blockade of MPhS cells; emergence and augmentation of counts of gigantic Pirogov-Langhans' cells characteristic of tuberculous granulomas, and also decrease in the counts of lymphocytes.

Patients exposed to quartz dust had some special morphological picture of affected lymph nodes: periadenitis, dust caseosis and tubercula in the presence anthracosilicosis sclerosis. Silicotuberculous broncho-adenitis in silicosis patients is characterized by solitary lesions of the lymph nodes, bronchi, rare dissemination to the lungs.

Basing on 42 post-mortem examinations of silicotuberculosis cases, the contributors display the most frequently encountered errors in diagnosing this disease. Silicotuberculous bronchadenitis, conglomerate-cirrhotic lower-lobe silicotuberculosis and their complications (e.g.
