[Granulomatous hepatitis caused by nomifensine]

Summary
Nomifensin treatment can cause granulomatous hepatitis, a liver condition characterized by inflammation and fever. Discontinuation of the drug led to recovery, suggesting an allergic reaction to nomifensin.
Area of Science:
- Hepatology
- Clinical Pharmacology
Background:
- Nomifensin is an antidepressant medication.
- Drug-induced liver injury is a significant clinical concern.
Observation:
- Four patients developed granulomatous hepatitis 4-6 weeks after nomifensin treatment.
- Liver biopsies showed granulomas in portal tracts and parenchyma with eosinophils and giant cells.
- Patients experienced fever episodes after nomifensin ingestion.
Findings:
- Elevated liver enzymes (alkaline phosphatase, alanine aminotransferase) and bilirubin were observed.
- Symptoms resolved within 6-10 weeks after discontinuing nomifensin.
- Re-challenge with nomifensin provoked fever, supporting a drug-induced etiology.
Implications:
- The findings suggest an allergic mechanism for nomifensin-induced granulomatous hepatitis.
- Clinicians should consider drug fever and liver abnormalities in patients treated with nomifensin.
- This highlights the importance of monitoring liver function during nomifensin therapy.
