TAG:铁剂在接受抗肿瘤坏死因子-α药物治疗的炎症性肠病患者中的作用

2020-09-24 MedSci原创 MedSci原创

炎性肠病(IBD)是一种慢性炎性疾病,其主要形式为溃疡性结肠炎(UC)和克罗恩病(CD)。IBD的主要症状和体征在肠道。但是,肠外表现很常见。

        炎性肠病(IBD)是一种慢性炎性疾病,其主要形式为溃疡性结肠炎(UC)和克罗恩病(CD)。IBD的主要症状和体征在肠道。但是,肠外表现很常见。贫血是IBD的常见肠外表现, IBD患者的贫血会显着增加医疗保健成本,并对生活质量产生负面影响。在IBD患者贫血的发病率约为20-30%,IBD患者的贫血可能源于多种原因。最常见的是由出血和吸收障碍引起的铁缺乏症。根据欧洲克罗恩和结肠炎组织(ECCO)指南,建议对所有IBD缺铁性贫血患者补充铁。肿瘤坏死因子-α(TNF-α)抑制剂(英夫利昔单抗和阿达木单抗)是IBD患者的一线生物疗法,黏膜愈合是治疗慢性炎性疾病的关键。IBD患者使用抗TNF-α药物对贫血或血红蛋白(Hb)水平影响的数据比较少,因此,本项研究旨在评估补充铁对初次使用抗TNF-α药物治疗的IBD患者的效果。

 

        研究人员分析了来自接受抗TNF-α治疗的79名IBD患者的数据。将患者分为未接受铁剂治疗的抗TNF-α(n  = 52)和补充铁的抗TNF-α(n  = 27)组。在基线(第0年)和1年后评估对实验室参数,贫血患病率和疾病活动性的影响。

 

 

         两组患者的第0年和第1年之间的血红蛋白(Hb)水平显着升高[抗TNF-α组为12.0±1.8–13.3±2.0 g / dL(p  <0.001)和补充铁剂组为9.8±2.4–11.7±2.3 g / dL(p=0.004)]。在严重贫血的IBD患者的亚组分析中, 与抗TNF-α组(9.3±9.3)相比,补铁增加了Hb水平的改善幅度(8.5±1.5-11.4±2.1 g / dL;p = 0.001)。与0年相比,两组在1年时的疾病活动均得到显着改善。持续性贫血与基线时的严重贫血显着相关(p = 0.017)。

 

 

 

         在患有IBD的贫血患者中,抗TNF-α药物可以改善贫血的临床症状,而与铁的补充无关。但是,补充铁可能对IBD严重贫血的患者有帮助。
