title: Hypercoagulability in acute bleeding peptic ulcer disease assessed by thrombin-antithrombin III concentrations.
abstract: OBJECTIVE
  To find out whether patients with acute bleeding peptic ulcers have hypercoagulable blood.
  
  
  METHODS
  Prospective open study.
  
  
  METHODS
  District hospital in Sweden.
  
  
  METHODS
  54 consecutive patients with duodenal ulcer (n = 25) and gastric ulcer (n = 29) admitted with haematemesis or melaena, or both.
  
  
  METHODS
  Diagnosis verified on admission by endoscopy, and healing was examined at follow up. Consumption of non-steroidal anti-inflammatory drugs, and smoking habits, were recorded.
  
  
  METHODS
  Coagulation of the blood monitored by concentrations of plasma thrombin-antithrombin III (TAT) complex in samples obtained on admission for the acute bleeding episode and at follow up 1-2 months later.
  
  
  RESULTS
  The plasma TAT complex concentrations were raised during the acute bleeding episode (p < 0.001) compared with an age matched reference group. The TAT complex concentrations measured at follow up had returned to the reference range in all patients, whether or not their ulcers had healed.
  
  
  CONCLUSIONS
  The results indicate that patients with acute haemorrhage from peptic ulcers have hypercoagulable blood during the acute episode.
