[Incidence and pattern of bronchial system lesions in patients with respiratory tuberculosis under the present conditions]. / Chastota i kharakter porazheniia bronkhial'noi sistemy u bol'nykh tuberkulezom organov dykhaniia v sovremennykh usloviiakh.

The paper presents the detection rates of active and inactive bronchial tuberculosis in patients with different clinical forms of respiratory tuberculosis in 1988-1989 (90 patients) and 1996-1997 (384 patients), comparatively characterizes the clinical forms of bronchial tuberculosis. There was a substantial increase in the detection rates of postprimary active and inactive bronchial tuberculosis.

[Lesions of the bronchial system in patients of different age groups with tuberculosis of the respiratory organs]. / Porazheniia bronkhial'noi sistemy u bol'nykh tuberkulezom prganov dykhaniia raznykh vozrastnykh grupp.

The results of bronchological examinations were analysed in 650 patients (between the ages of 1 and 89 years) with tuberculosis of respiratory organs. Three age groups were specified: group I included children and adolescents to 17 years (152 subjects); group II-adults aged 18 to 59 years (408 subjects), and group III--those aged 60 to 89 years (90 subjects). In group I active bronchial tuberculosis was diagnosed in 14.3% of the cases, residual changes after past tuberculosis in 11.1%, nonspecific endobronchitis in 33.3%; the respective figures for group II were 7.1%, 11% and 43.3% and those for group III 20%, 31.1% and 24.4% of the cases. Isolated froms of bronchial tuberculosis account for 0.9% among all clinical froms of tuberculosis of respiratory organs. Nonspecific endobronchitis in cases with tuberculosis of respiratory organs occur in the form of bilateral catarrhal processes. With age catarrhal changes decline from 92.2% to 54.7% and atrophic and hypertrophic bronchial changes increase and amount to 9.2% and 22.3%, respectively. The character of bronchial pathology is determined by the initial forms of tuberculosis.

[Antigenic composition of immune complexes in the blood and bronchoalveolar lavage fluid of patients with tuberculosis and aspecific inflammatory diseases of the respiratory organs]. / Antigennyi sostav immunnykh kompleksov v syvorotke krovi i bronkhoal'veoliarnom smyve bol'nykh tuberkulezom i nespetsificheskimi vospalitel'nymi bolezniami organov dykhaniia.

The level and antigenic composition of immune complexes (ICs) in 49 patients with nonspecific inflammatory diseases of the respiratory organs (NIDRO) and tuberculosis were studied in relation to separate indices of systemic and local immunity. Involvement of the ICs in the pathogenesis of tuberculosis and NIDRO was shown and the role of the level and composition of the ICs in the prognosis and differential diagnosis of the indicated pathological processes was revealed. It was noted that in patients with active tuberculosis and in patients with chronic bronchitis and residual lesions after cured tuberculosis of the respiratory organs the ICs mainly formed by antigenic substances of tubercle bacilli. In the patients with chronic bronchitis and suppurative affections of the lungs the ICs formed due to antigenic substances of bacterial infections. The use of a technique for simultaneous cleavage of the ICs in blood and bronchoalveolar secretion provided determination of etiology of the inflammatory processes in the lungs and bronchi. The technique proved to be highly efficient for early differential diagnosis of tuberculosis and NIDRO.
