Abstract

OBJECTIVES:

Our aim was to determine whether tissue factor pathway inhibitor (TFPI), a physiologically important natural anticoagulant that acts by inhibiting the extrinsic pathway, concentrations decrease as liver disease progresses, and, second, whether TFPI has an etiologic role in portal vein thrombosis in cirrhotics.

METHODS:

After taking their informed consent, we determined TFPI concentrations in the plasma of healthy subjects (group I) (n = 15) (average age, 45.1 = 11.8 yr), cirrhotics (group II) (n = 16) (average age, 43.6 +/- 9.8 yr), and cirrhotics with portal vein thrombosis (group III) (n = 12) (average age, 42.6 +/- 10.7 yr). Mean and median TFPI values and interquartile ratios were determined for groups I, II, and III. Then group II and III were further divided according to the Child classes A, B, or C, and mean and median TFPI values and interquartile ratios were determined for these classes as well. Using the Man-Whitney U test, we compared the results.

RESULTS:

Statistically important differences were documented (p = 0.005) between the median TFPI levels of healthy adults and Child C cirrhotics (concentration lower in Child C) and between normal subjects and cirrhotics with portal vein thrombosis (p = 0.02) (TFPI concentration being lower in the latter group again).

CONCLUSIONS:

TFPI concentration decreases in advanced liver disease, and this may be a contributory factor for portal vein thrombosis in at least some cases of cirrhotics.
