A case of ceftriaxone-induced liver injury and literature review.

Background: Liver injury evoked by drugs spans various clinical manifestations ranging from mild biochemical abnormalities to acute liver failure. Ceftriaxone is a third-generation cephalosporin often used in clinical practice for its long half-life, high tissue penetration rate, wide spectrum and good safety profile. Ceftriaxone, as other cephalosporins have little hepatotoxicity; however, few cases of toxic hepatitis induced by this antibiotic have been reported.

Case Presentation: We describe a case of acute, drug-induced liver injury ('hepatitis') in a 77 years-old female patient treated with ceftriaxone for pneumonia. After 48 hours from antibiotic administration, clinical condition worsened with a clinical and laboratory profile compatible with an acute non cholestatic liver injury. Ceftriaxone administration was immediately stopped and the patient was treated with hydro-electrolyte replacement, high-flow oxygen, vitamin K infusion, steroids and proton-pump inhibitors with a progressive clinical improvement.

Conclusions: Even if rare, a ceftriaxone-induced hepatotoxicity (confirmed by RUCAM score), should be considered when all other possible causes have been excluded.
