title: [Diagnostic features of primary and secondary pulmonary tuberculosis].
abstract: Comprehensive clinical, X-ray, and laboratory studies were made of 495 patients with primary pulmonary tuberculosis and 250 with secondary tuberculosis. The patients' age was 18 years. Age-specific, clinical, X-ray, microbiological, immunological, and metabolic features of the disease were revealed in relation to its genesis. It was found that it was difficult to make a diagnosis in primary tuberculosis more frequently and to define the intensity of the disease in secondary tuberculosis. Sputum tests for bacterial and altered forms of Mycobacterium tuberculosis enhanced the verification of primary tuberculosis by 16% and secondary tuberculosis by 29%. Immunological and biochemical studies used in clinical and X-ray examinations permit the increase in the detection rate of primary and secondary tuberculosis from 41.7 to 79.6% and from 37.6 to 81.4%, respectively.
