[Lesions of the bronchial system in patients of different age groups with tuberculosis of the respiratory organs].
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.
