Factor VII in liver cirrhosis

Area of Science:

• Hepatology
• Hematology
• Biochemistry

Background:

• Liver cirrhosis can affect coagulation factor synthesis.
• Factor VII is a vitamin K-dependent clotting factor crucial for hemostasis.
• Understanding Factor VII metabolism in cirrhosis is vital for managing bleeding risks.

Purpose of the Study:

• To investigate Factor VII activity and cross-reacting material (CRM) in liver cirrhosis patients.
• To assess the impact of vitamin K1 administration on Factor VII levels.
• To explore correlations between Factor VII, clinical presentation, and albumin levels.

Main Methods:

• Studied Factor VII activity and CRM in plasma of liver cirrhosis patients before and after vitamin K1.
• Grouped patients based on clinical findings like ascites and portal hypertension.
• Analyzed correlations between Factor VII levels, clinical status, and albumin.

Main Results:

• A significant correlation (p < 0.001) was observed between Factor VII activity and CRM in all patients.
• Patients with severe cirrhosis (ascites, portal hypertension) had significantly lower Factor VII activity and CRM.
• Vitamin K1 administration did not alter Factor VII levels in any patient group.
• Factor VII levels correlated with albumin levels in patients without severe cirrhosis complications.

Conclusions:

• Advanced liver cirrhosis, particularly with ascites and portal hypertension, is associated with reduced Factor VII activity and CRM.
• Vitamin K1 therapy is ineffective in improving Factor VII levels in these patients.
• The findings suggest a lack of immunologically detectable Factor VII precursors in liver cirrhosis of unknown etiology.
