Thiopurines (azathioprine and mercaptopurine) are one of the immunosuppressive mainstays for the treatment of inflammatory bowel disease. In spite of its widespread use, thiopurine metabolism is still not fully understood, and a significant proportion of patients suffer toxicity or lack of efficacy. Different enzymatic pathways with individual variations constitute a pharmacogenetic model that seems to be suitable for monitoring and therapeutic intervention. This review is focused on current concepts and recent research that may help clinicians to rationally optimise thiopurine treatment in patients with inflammatory bowel disease.
硫嘌呤类药物(硫唑嘌呤和巯嘌呤)是治疗炎症性肠病的主要免疫抑制剂之一。尽管其广泛应用,但硫嘌呤的代谢仍未完全了解,且相当一部分患者会出现毒性反应或疗效不佳。具有个体差异的不同酶促途径构成了一个药物遗传学模型,似乎适用于监测和治疗干预。本综述聚焦于当前的概念和最新研究,这些可能有助于临床医生合理优化炎症性肠病患者的硫嘌呤治疗。
