title: Effect of inhaled tiotropium on spirometric parameters in patients with tuberculous destroyed lung.
abstract: BACKGROUND
  In Korea, patients with destroyed lung due to tuberculosis (TB) account for a significant portion of those affected by chronic pulmonary function impairment. The objective of our research was to evaluate the efficacy of inhaled tiotropium bromide in TB destroyed lung.
  
  
  METHODS
  We compared the effectiveness of inhaled tiotropium bromide for 2 months between pre- and post-treatment pulmonary function tests performed on 29 patients with destroyed lung due to TB.
  
  
  RESULTS
  The mean age of the total number of patients was 63±9 years, where 15 patients were male. The pre-treatment mean forced expiratory volume in 1 second (FEV1) was 1.02±0.31 L (44.1±16.0% predicted). The pre-treatment mean forced vital capacity (FVC) was 1.70±0.54 L (52.2±15.8% predicted). Overall, the change in FEV1% predicted over baseline with tiotropium was 19.5±19.1% (p<0.001). Twenty patients (72%) got better than a 10% increase in FEV1 over baseline with tiotropium, but one patient showed more than a 10% decrease in FEV1. Overall, the change in FVC% predicted over baseline with tiotropium was 18.5±19.9% (p<0.001). Seventeen patients (59%) experienced greater than a 10% increase in FVC over baseline with tiotropium; 12 (41%) patients had stable lung function.
  
  
  CONCLUSIONS
  The inhaled tiotropium bromide therapy may lead to improve lung functions in patients with TB destroyed lung. However, the long-term effectiveness of this treatment still needs to be further assessed.
