A case of idiosyncratic liver injury after oxaliplatin‐induced thrombocytopenia

WHAT IS KNOWN AND OBJECTIVE: Oxaliplatin is a platinum drug used for treating digestive cancers that can lead to drug-induced thrombocytopenia (DITP). We report a case of oxaliplatin-induced anaphylaxis and DITP, complicated by idiosyncratic drug-induced liver injury (IDILI). CASE SUMMARY: A 46-year-old woman with rectal cancer developed anaphylaxis shortly after oxaliplatin administration (post-operative CapeOX), presenting with low platelet count (0.2 x 10(4) /microL) and elevated aspartate aminotransferase (1091 IU/L) and alanine aminotransferase (1010 IU/L) by day 10. Following 50 mg/d prednisolone administration from day 9, she left the hospital on day 36 after recovering. WHAT IS NEW AND CONCLUSION: This is the first case report of oxaliplatin-induced IDILI and its effective treatment with steroids.
