INTRODUCTION There is paucity of data on the incidence of severe thiopurine (TP)-induced myelosuppression (TIM) among inflammatory bowel disease (IBD) patients. METHODS Utilizing the Veterans Affairs Healthcare system we identified IBD patients with normal pre-treatment thiopurine S-methyltransferase(TPMT) levels who received TPs for 6 months and developed severe TIM. RESULTS Among 73,392 IBD patients, 14,760 had received TPs, and 2823 had a normal TPMT level. The incidence rate of severe TIM was 1.25 per 1000 patient-years. DISCUSSION The incidence of severe TIM was very low, calling into question the necessity of frequent long-term CBC monitoring among IBD patients on TPs.

硫嘌呤的发生率在全国炎症性肠病患者队列中诱导了严重的骨髓抑制。



引言 关于炎症性肠病 (IBD) 患者中严重硫嘌呤 (TP) 诱导的骨髓抑制 (TIM) 发生率的数据很少。方法 利用退伍军人事务医疗保健系统,我们确定了治疗前硫嘌呤 S-甲基转移酶 (TPMT) 水平正常的 IBD 患者,这些患者接受了 TPs 6 个月并发展为严重的 TIM。结果 在 73,392 例 IBD 患者中,14,760 例接受了 TPs,2823 例 TPMT 水平正常。重症 TIM 的发病率为 1.25/1000 患者年。讨论 严重 TIM 的发生率非常低,这让人质疑 TPs 上的 IBD 患者频繁长期监测 CBC 的必要性。
