To report our experience with the use of granulocytapheresis (GCAP) in 14 patients with active steroid-refractory inflammatory bowel disease (IBD) in order to evaluate its efficacy in achieving remission and maintaining a long lasting symptom-free period.
The activity of the disease was evaluated by clinical activity index (CAI) and endoscopic index (EI) in ulcerative colitis (UC), while by Crohn's disease activity index (CDAI) in Crohn's disease (CD). The patients were treated using the Adacolumn system, an adsorption column which selectively binds to granulocytes and monocytes. One session/week of GCAP was performed for 5 wk. Steroids were stopped during apheresis.
All the patients completed the five-week course showing no complications. At the end of the last session, 93% of patients showed a clinical remission of the disease that persisted for 6 mo. Nine months after the end of the treatment, 60% of the cases maintained remission, while 23% of the patients were still in clinical remission after 12 mo.
Even if the number of our patients with steroid-refractory IBDs was not big, we can assert that GCAP is well tolerated and effective, especially in the first six months after the treatment, in a significant percentage of cases. The rate of sustained response drops slightly after 6 mo and significantly after 12 mo, however the absence of severe side effects can be a stimulus for further evaluating new schedules of treatment.
报告我们对14例活动性类固醇难治性炎症性肠病(IBD)患者使用粒细胞单采术(GCAP)的经验,以评估其在实现缓解和维持长期无症状期方面的疗效。
通过临床活动指数(CAI)和内镜指数(EI)评估溃疡性结肠炎(UC)的疾病活动度,而通过克罗恩病活动指数(CDAI)评估克罗恩病(CD)的疾病活动度。使用Adacolumn系统对患者进行治疗,该系统是一种能选择性结合粒细胞和单核细胞的吸附柱。每周进行1次GCAP治疗,共进行5周。单采期间停用类固醇。
所有患者均完成了为期5周的疗程,未出现并发症。在最后一次治疗结束时,93%的患者疾病达到临床缓解,且缓解持续了6个月。治疗结束9个月后,60%的病例维持缓解,而12个月后仍有23%的患者处于临床缓解状态。
即使我们治疗的类固醇难治性IBD患者数量不多,但我们可以断言,GCAP耐受性良好且有效,尤其是在治疗后的前6个月,相当比例的病例中是如此。6个月后持续缓解率略有下降,12个月后显著下降,然而,由于没有严重副作用,这可能促使进一步评估新的治疗方案。
