Summary

In liver disease patients, Anti-thrombin III (AT III) levels were significantly reduced more often than prothrombin time (PT) or fibrin polymerization curve (FPC) abnormalities. AT III is a more sensitive indicator of hepatocellular dysfunction.

Area of Science:

  • Hepatology
  • Hematology
  • Clinical Biochemistry

Background:

  • Liver disease significantly impacts coagulation factor synthesis and function.
  • Assessing hepatocellular dysfunction requires sensitive and specific diagnostic markers.

Purpose of the Study:

  • To compare the sensitivity of prothrombin time (PT), Anti-thrombin III (AT III), and fibrin polymerization curve (FPC) in evaluating liver disease severity.
  • To determine the most effective coagulation parameter for assessing hepatocellular dysfunction.

Main Methods:

  • Simultaneous measurement of PT, AT III levels, and FPC in patients with liver disease.
  • Patients were categorized into two groups: cirrhosis (n=37) and miscellaneous liver disease (n=35).

Main Results:

  • Significant PT prolongation observed in 82% of cirrhotics vs. 17% of miscellaneous liver disease patients.
  • Significant AT III reduction noted in 94% of cirrhotics vs. 31% of miscellaneous liver disease patients.
  • Abnormal FPC observed in 88% of cirrhotics vs. 32% of miscellaneous liver disease patients. Good correlation between PT and AT III levels.

Conclusions:

  • Anti-thrombin III (AT III) measurement is a more sensitive indicator of hepatocellular dysfunction than PT or FPC.
  • AT III levels provide a more comprehensive assessment of coagulation abnormalities in liver disease.
