Abstract

Thiopurines are a class of immunosuppressant and antineoplastic agents. They are widely used in the treatment of inflammatory bowel disease, haematological malignancies and autoimmune diseases, but can cause significant toxicity. Inherited gene mutations are now recognized as independent risk factors for severe adverse drug reactions to thiopurines even at 10-fold dose reductions. We present a case of thiopurine toxicity resulting in severe myelosuppression, hepatotoxicity and alopecia in an individual with homozygous *3/*3 loss-of-function alleles in the NUDT15 gene. Our case highlights important differences in gene mutation frequencies between races that can help guide pharmacogenomic testing.

nut15缺乏症患者硫嘌呤起始治疗后严重骨髓抑制和脱发。
硫嘌呤类药物是一类免疫抑制剂和抗肿瘤药物。它们广泛用于治疗炎症性肠病、血液学恶性肿瘤和自身免疫性疾病,但可能引起显著的毒性。遗传基因突变现在被认为是硫嘌呤严重药物不良反应的独立危险因素,即使剂量减少10倍。我们报告了一例硫嘌呤毒性导致严重骨髓抑制、肝毒性和脱发的病例,该病例发生在NUDT15基因中具有纯合子*3/*3功能缺失等位基因的个体中。我们的病例强调了种族间基因突变频率的重要差异,这有助于指导药物基因组学测试。
