title: Plasma prekallikrein as a prognostic indicator in chronic liver insufficiency.
abstract: The prognostic value of plasma prekallikrein activity, prothrombin time, and serum albumin with regard to survival in chronic liver insufficiency was evaluated in 21 consecutive patients. Twenty patients had liver cirrhosis, and one patient had malignant liver disease (hepatocellular carcinoma). Eight patients died between 4 and 43 days after the time of blood sampling. These patients had a prekallikrein value less than 0.42. There were no overlapping prekallikrein values between patients who died and patients who survived (overlap index 0; p less than 0.001). Overlap index for prothrombin time was 0.35 (p less than 0.02), and for serum albumin 0.34 (p less than 0.02). In conclusion, plasma prekallikrein seems to indicate whether death is imminent in patients with liver insufficiency due to cirrhosis. Longitudinal studies of prekallikrein activity in different subgroups of patients with chronic and acute liver disease are recommended.
