AP&T: 存在肛周克罗恩病患者需长期使用抗肿瘤坏死因子治疗

2019-11-30 不详 MedSci原创

肛周克罗恩病患者停止抗肿瘤坏死因子(TNF)治疗后,其预后情况目前还不清楚,因此,本项研究旨在评估停止抗TNF治疗后肛周克罗恩病(CD)的复发率。

背景
肛周克罗恩病患者停止抗肿瘤坏死因子(TNF)治疗后,其预后情况目前还不清楚,因此,本项研究旨在评估停止抗TNF治疗后肛周克罗恩病(CD)的复发率。

方法
研究人员从1997年至2019年6月间在香港,上海,台湾,马来西亚,泰国和新加坡等机构的前瞻性肠炎数据库中检索接受抗TNF治疗并随后终止治疗的存在肛周病变的CD患者的数据。使用Kaplan-Meier方法估计了肛周CD复发的累积概率。

结果
在中位随访时间为89个月(四分位间距[IQR]:65-173个月)后,78例肛周CD患者中有44例(56.4%)在停止抗TNF后复发,复发定义为瘘管引流增加。在12、36和60个月时,肛周CD复发的累计概率分别为50.8%,72.6%和78.0%。诊断为CD时年龄较小[调整后的危险比(HR):1.04;95%CI 1.01-1.09;P=.04]与肛周CD复发的机会更高相关。在肛周CD复发的患者中(n = 44),在29例患者中有24例接受抗TNF的治疗后可缓解。十二名(27.3%)患者需要进行手术治疗。维持硫嘌呤与减少复发的可能性没有关系[HR = 1.10; 95%CI:0.58-2.12; P=.77]。在17例实现肛周CD放射学缓解的患者中,有5例(35.3%)在中位6个月后停止抗TNF治疗后复发。

结论
超过一半的肛周CD患者在停止抗TNF治疗后出现复发。恢复抗TNF后,大多数恢复了反应。然而,超过四分之一的复发性肛周CD患者需要去功能手术。停止抗TNF治疗前的放射学评估对肛周CD至关重要。
