[Changes in lung function in patients with newly-diagnosed tuberculosis during treatment with short courses of controlled drug therapy].

In 54 new cases of tuberculosis, VC, FVC, FEV1, FEV1/VC%, PEF, MEF25, MEF50, MEF75, PaO2, PaCO2 were measured before, during, and after a short-term intensive controlled chemotherapy. Lung function improved in 57.4% of patients and deteriorated in 22.2%. There was a combination of better and worse lung function in 7.4%. The direction of functional changes depended on the form of tuberculosis, the extent of a tuberculous process, the duration and efficiency of chemotherapy.
