Abstract: Objective To analyze the acute drug-induced liver injury caused by low-dose cyclophosphamide for injection in a patient with relapsing polychondritis so as to provide a reference for clinicians. Methods The clinical data of a patient with relapsing polychondritis who developed acute drug-induced liver injury after the first low-dose intravenous application of cyclophosphamide was analyzed. The related literature was reviewed. Results The patient presented with acute liver injury after the first low-dose intravenous application of cyclophosphamide. After correlation analysis and multidisciplinary consultation, the patient was diagnosed with acute cyclophosphamide-induced liver injury. Cyclophosphamide was discontinued, and liver protection therapy was initiated, which led to a good prognosis. Conclusion Individual differences in adverse reactions deserve attention among patients who use cyclophosphamide for the first time. This drug should be used with caution. It is critical to identify the risk factors and assess the type and severity of cyclophosphamide induced liver injury so as to adjust the treatment in time.
