BACKGROUND/AIMS: Reports on drug-induced liver injury due to benzylpenicillin are scarce and predominantly describe cases of intrahepatic cholestasis. To our knowledge, no immunologically documented case of hepatocellular liver injury due to benzylpenicillin has been reported so far.
CASE REPORT: A previously healthy man required long-term therapy with benzylpenicillin because of vertebral spondylitis. After 4 weeks of treatment, liver tests showed a marked increase in transaminases associated with high peripheral eosinophil counts. Discontinuation of benzylpenicillin resulted in gradual recovery.
INVESTIGATIONS: Levels of eosinophil cationic protein were elevated, indicating eosinophil activation and the presence of an immunoallergic reaction. Skin tests and assays for specific Ig E-antibodies to benzylpenicillin were negative, but lymphocyte transformation tests demonstrated T-cell sensitization to benzylpenicillin.
CONCLUSIONS: According to current causality assessment schemes, our report constitutes a probable case of drug-induced hepatocellular liver injury due to benzylpenicillin.
