Summary

This study investigates Syncumar-induced chronic hepatitis in a patient with prosthetic valves. Lymphocyte chromatin activation confirmed drug-induced liver injury, which resolved after switching to Marcoumar.

Area of Science:

  • Hepatology
  • Pharmacology
  • Immunology

Background:

  • Anticoagulant therapy is crucial for patients with prosthetic heart valves.
  • Drug-induced liver injury (DILI) is a significant clinical concern.
  • Syncumar (acenocoumarol) is a vitamin K antagonist anticoagulant.

Observation:

  • A patient on chronic Syncumar treatment developed chronic hepatitis.
  • The patient required continued anticoagulation due to prosthetic valve insertion.
  • Lymphocyte chromatin activation was assessed to evaluate potential DILI.

Findings:

  • Syncumar and related anticoagulants induced a positive chromatin activation response in lymphocytes.
  • Elevated serum bilirubin and transaminase levels indicated liver injury.
  • Liver function markers improved with treatment modification and discontinuation of Syncumar.

Implications:

  • This case highlights the potential for Syncumar to cause chronic hepatitis.
  • Lymphocyte chromatin activation may serve as a biomarker for DILI.
  • Switching to Marcoumar (phenprocoumon) effectively managed the drug-induced liver injury.
