Antithrombin activity in chronic obstructive bronchopneumopathy

In a group of 22 patients affected by chronic obstructive bronchopathies (COBP) with respiratory insufficiency and at the same time in a group of 12 controls, were determined plasma Antithrombin (AT) III concentrations. The mean of AT III level in patients with COBP was 40.5% and was 96.8% in the controls. On the basis of these data, the authors think that in patients with COBP decrease AT III can cause the rising of bleeding complications.
