Abstract

We present a case of a 49-year-old woman diagnosed with aquaporin-4 antibody-positive transverse myelitis, who developed a significant transaminitis 2 months after commencing mycophenolate mofetil (MMF) as a steroid-sparing agent. No other risk factors were identified, a blood liver panel was negative and liver biopsy showed features compatible with drug-induced liver injury (DILI). MMF was stopped with a corresponding normalisation of serum alanine aminotransferase over the next 2 months. This case highlights MMF as a rare cause of DILI and provides justification for monitoring of liver biochemistry on therapy.

摘要

我们报告了一例 49 岁女性,诊断为水通道蛋白 4 抗体阳性的横贯性脊髓炎,在开始使用吗替麦考酚酯(MMF)作为类固醇保肺剂 2 个月后,出现明显的转氨肝酶升高。未发现其他危险因素,肝功能检查正常,肝活检显示符合药物性肝损伤(DILI)的特征。停用 MMF 后,接下来的 2 个月内血清丙氨酸氨基转移酶恢复正常。该病例强调了 MMF 是导致 DILI 的罕见原因,并证明在治疗过程中监测肝功能是合理的。
