Summary
Phenprocoumon (Marcoumar) can cause drug-induced hepatitis, leading to cirrhosis. This case highlights the importance of considering medication side effects in liver disease diagnosis.
Area of Science:
- Hepatology
- Toxicology
- Internal Medicine
Background:
- Drug-induced liver injury (DILI) is a significant clinical concern.
- Phenprocoumon, an anticoagulant, has been associated with various adverse effects.
- Accurate diagnosis of DILI is crucial for patient management and preventing complications.
Observation:
- A 58-year-old male developed jaundice post-aortic valve replacement.
- Initial suspicion of non-A, non-B hepatitis was investigated.
- Liver biopsy revealed centrilobular necrosis with eosinophilic infiltration.
Findings:
- Recurrent jaundice upon phenprocoumon re-exposure confirmed drug-induced hepatitis.
- Hepatitis C virus antibodies were notably absent.
- The condition progressed to liver cirrhosis despite initial management.
Implications:
- This case underscores the necessity of thorough medication review in unexplained hepatitis.
- Early identification and withdrawal of causative agents like phenprocoumon can prevent severe liver damage.
- Aortic valve replacement with a bioprosthesis was performed to discontinue anticoagulation therapy.
