title: Profound imbalance of pro-fibrinolytic and anti-fibrinolytic factors (tissue plasminogen activator and plasminogen activator inhibitor type 1) and severe bleeding diathesis in a patient with cirrhosis: correction by liver transplantation.
abstract: A 49-year-old male with alcoholic cirrhosis suffered several spontaneous, life-threatening, deep muscle bleeding episodes. Laboratory evaluation indicated excessive fibrinolysis with low plasminogen, low alpha2-antiplasmin, undetectable plasminogen activator inhibitor type 1 (PAI-1) activity, high tissue plasminogen activator (t-PA) activity and high t-PA antigen. Treatment with oral anti-fibrinolytic agents prevented further bleeding episodes. Decompensated cirrhosis eventually necessitated orthotopic liver transplantation. Post-operatively, the patient did not require oral anti-fibrinolytic agents, and there were no significant bleeding events. Circulating PAI-1 activity, t-PA activity and antigen normalized by 3 months post transplant. In short, the profound bleeding diathesis, as well as the imbalance in t-PA and PAI-1 levels, corrected after liver transplantation. Recognition of such patients is important, because the bleeding diathesis is an indication rather than a contraindication for orthotopic liver transplantation.
