Summary
Dicoumarol, a coumarin derivative, may cause severe liver injury. This case report details a fatal mixed hepatocellular-cholestatic liver disease in a patient after dicoumarol treatment, with no other cause identified.
Area of Science:
- Hepatology
- Pharmacology
- Toxicology
Background:
- Coumarins are known for unpredictable hepatic injury.
- Dicoumarol's direct causal link to liver damage is not well-established in existing literature.
Observation:
- A 73-year-old female patient presented with severe liver disease.
- The liver disease was characterized as a mixed hepatocellular-cholestatic type.
- The patient had been undergoing dicoumarol treatment for three months prior to presentation.
Findings:
- The patient developed fatal liver disease.
- Extensive diagnostic evaluations excluded other potential etiologies for the liver condition.
- The clinical presentation strongly suggests dicoumarol as the causative agent.
Implications:
- This case highlights a potential severe hepatotoxic effect of dicoumarol.
- It underscores the importance of considering drug-induced liver injury in patients on coumarin therapy.
- Further investigation into dicoumarol's hepatotoxicity may be warranted.
