JCC:第6周粪钙卫蛋白水平可以很好的预测克罗恩病患者长期内镜治疗的效果

2020-09-16 MedSci原创 MedSci原创

克罗恩病(CD)是一种胃肠道炎症性疾病,其特征在于缓解期和复发期反复交替。患者会出现例如腹痛,腹泻,肠梗阻以及肛周瘘管等临床表现。

        克罗恩病(CD)是一种胃肠道炎症性疾病,其特征在于缓解期和复发期反复交替。患者会出现例如腹痛,腹泻,肠梗阻以及肛周瘘管等临床表现。传统的观念与治疗一直集中在患者临床症状的改善上,但是最近,内镜愈合已成为新的治疗目标,因为内镜愈合的实现与长期结果的改善相关。但是,反复进行结肠镜检查以评估内镜愈合情况可能无法为患者所接受。因此,人们越来越希望使用与内窥镜检查密切相关的生物标志物来替代结肠镜检查。其中粪钙卫蛋白引起人们的兴趣,粪钙卫蛋白是中性粒细胞的胞质成分,并随着中性粒细胞的活化和降解而释放。有研究已报道钙卫蛋白浓度与CD内镜活动之间存在相关性。有研究认为粪钙卫蛋白的临界值为250mg/kg时有很好的预测价值,但是当活动性炎症存在时,受累程度有限的患者可能没有那么高的钙卫蛋白水平。结果,相比于绝对临界值,钙卫蛋白的基线变化可能更能预后。因此,本项研究的目的是评估粪便钙卫蛋白的变化情况对短期和长期临床及内镜结果的预测性能。

 

        研究人员从3项前瞻性研究中收集病人资料,总共纳入677例患者,评估6周时间内钙网蛋白与内镜下疾病活动度的关系,从基准开始的粪钙卫蛋白用于预测在8、32和52周克罗恩病的预后的结果。使用针对混杂因素调整的多元逻辑回归模型评估第6周的临床和生物标志物评估与第52周的内镜缓解(ER)之间的关系。

 

         结果显示第6周粪钙卫蛋白<250 mg / kg表现出了良好的预测52周ER的能力(AUC 0.709,95%CI 0.566-0.852,p = 0.014),并且比其他时间点的粪钙卫蛋白截止值和基线差异要好用于预测52周的ER。校正协变量后,第6周粪便钙卫蛋白<250 mg / kg的患者发生ER第52周的机会增加了3.48倍(95%CI 1.31-9.28,p = 0.013)。其他第6周的临床评估(临床缓解或临床反应)或生物标志物(CRP <5或药物水平)与52周的ER没有关联。

 

        因此,本项研究表明分析第六周的粪钙网蛋白水平<250mg/Kg可预测未来的内镜治疗的治疗效果,并且可以比临床症状提供更多的信息。
