Insights
Liver cirrhosis patients show an imbalance in clotting factors, with higher factor VIII and lower protein C, indicating a risk for bleeding or thrombosis. Low protein C function (PICI%) suggests hypercoagulability.
Area of Science:
- Hepatology
- Hematology
- Coagulation Science
Background:
- Liver cirrhosis impairs the production of most clotting factors.
- Despite impaired clotting factor synthesis, cirrhotic patients are susceptible to thrombosis.
- The study investigates procoagulant and anticoagulant factors in cirrhosis.
Purpose of the Study:
- To assess procoagulant and anticoagulant factors in cirrhotic patients.
- To correlate these factors with bleeding and/or thrombotic events.
- To identify markers of hypercoagulability in liver cirrhosis.
Main Methods:
- 102 subjects (51 cirrhotic, 51 controls) were enrolled.
- Evaluated clotting factors (Factor VIII, Protein C), coagulation times (INR, PT, PTT), and platelet counts.
- Assessed protein C system functionality using the Protac-induced coagulation inhibition percentage (PICI%) assay.
Main Results:
- Cirrhotic patients had significantly higher Factor VIII and Factor VIII/Protein C ratios compared to controls.
- Protein C levels and PICI% were significantly lower in cirrhotic patients.
- These findings suggest an altered coagulation balance in liver cirrhosis.
Conclusions:
- Cirrhotic patients exhibit an altered balance of coagulation factors, predisposing them to bleeding or thrombosis.
- Low PICI% indicates impaired anticoagulant function of the protein C system.
- A high Factor VIII/Protein C ratio and low PICI% may serve as indicators of hypercoagulability in liver cirrhosis.
Background And Study Aim:
Liver cirrhosis leads to decreased production of clotting factors that are generally all produced in the liver except factor VIII and von Willebrand factor. However, cirrhotic patients are not protected from thrombosis. The present study aimed to assess the procoagulant and anticoagulant factors in cirrhotic patients with and without bleeding and/or thrombotic events.
Patients And Methods:
A total of 102 adult subjects were enroled: 51 cirrhotic patients and 51 healthy controls. After full history taking with special attention given to thromboembolic and haemorrhagic events, platelet count, serum albumin, bilirubin, international normalised ratio (INR), PT, partial thromboplastin time (PTT), hepatitis B surface antigen (HBsAg), hepatitis B core (HBc) antibodies, hepatitis C virus (HCV) antibodies, factor VIII, protein C, Protac-induced coagulation inhibition percentage (PICI%) assay and abdominal ultrasound were performed for patients and controls. Upper gastrointestinal endoscopy was conducted for the patients.
Results:
Compared with control subjects, factor VIII and factor VIII/protein C were significantly higher, while protein C and PICI% were significantly lower among patients.
Conclusion:
Patients with liver cirrhosis may have a tendency for bleeding or thrombosis according to the balance of coagulant and anticoagulant status. PICI%, the assay that evaluated the functionality of the protein C anticoagulant system, was significantly lower in patients compared to control subjects. Accordingly, low PICI% and high factor VIII/protein C ratio can be taken as an index of hypercoagulability in cirrhotic patients.
