title: Effect of corticosteroids on hemostasis and pulmonary arterial pressure during chronic obstructive pulmonary disease exacerbation.
abstract: BACKGROUND
  Hemodynamic and hemostatic abnormalities are reportedly frequent in chronic obstructive pulmonary disease (COPD).
  
  
  OBJECTIVE
  We investigated the changes in systolic pulmonary artery pressure (PAPs) and hemostatic status and the effects of systemic steroid treatment (SST) during COPD exacerbation.
  
  
  METHODS
  Consecutive 26 male and 4 female patients as well as 10 controls were enrolled. The nonsteroid treatment (NST) group received standard treatment without steroids, and the other group received additional SST. Initial values of blood gases, spirometry and PAPs, P-selectin, D-dimer and fibrinogen levels, activities of thrombocyte aggregation, antithrombin III (AT III), protein C (PC), protein S, activated PC resistance (APCR), prothrombin time and partial thromboplastin time were obtained and compared with values at day 10.
  
  
  RESULTS
  Improvement in spirometry and blood gases was more prominent with SST. At presentation, patients had higher PAPs, P-selectin, D-dimer and fibrinogen but lower AT III levels than controls. PAPs and fibrinogen levels significantly decreased in the SST group while P-selectin levels further increased in the NST group. The D-dimer level significantly decreased in both groups. Means of AT III, PC and protein S increased in the SST and decreased in the NST group, but only the decrease in PC in the NST group was meaningful. Compared with the controls, AT III levels in the NST group and activated PC resistance in the SST group were significantly decreased. Thrombocyte aggregation tests suggested an incline after 10 days in both groups.
  
  
  CONCLUSIONS
  We suggest that in patients with COPD exacerbation, addition of systemic corticosteroids to treatment results in better outcome in normalization of PAPs, hemostasis, pulmonary functions and blood gases.
