[Clinical findings in patients with lung diseases caused by non-tuberculous mycobacteria in former East Germany and Hungary].

The importance of lung diseases caused by nontuberculous mycobacteria is increased. Clinical findings in 54 patients of the former GDR and 110 patients from Hungary were investigated. Most of the patients were men in average age of 55 years. More than 80% of the patients had an exposition and disposition, for instance, pre-existing pulmonary damage, such as healed tuberculosis, chronic bronchitis or emphysema. X-ray findings are presented and discussed. Signs and symptoms of disease are very similar to the pulmonary tuberculosis.
