IBD:Vedolizumab诱导治疗中重度溃疡性结肠炎后粪便钙卫蛋白浓度变化

2019-03-16 不详 MedSci原创

在溃疡性结肠炎(UC)患者中,粪便钙卫蛋白(FC)浓度与内镜下肠道炎症相关。本项研究调查了维多珠单抗诱导对FC浓度的影响以及FC浓度是否可以作为疾病状态的可靠生物学指标。

背景
溃疡性结肠炎(UC)患者中,粪便钙卫蛋白(FC)浓度与内镜下肠道炎症相关。本项研究调查了维多珠单抗诱导对FC浓度的影响以及FC浓度是否可以作为疾病状态的可靠生物学指标。

方法
来自3期试验GEMINI 1的患者数据被用于评估第6周FC浓度与临床表现之间的关系(包括临床缓解,粘膜愈合[MH]和内镜缓解)以及绝对FC浓度值和相对FC浓度变化与基线的关系。

结果
GEMINI 1试验诱导期招募了895名患者。与无症状患者相比,获得临床缓解,MH和/或内镜缓解患者的粪便钙卫蛋白浓度降低更加明显。临床或内镜缓解的最佳第6周FC浓度为≤150μg/ g。同时研究人员发现基线FC浓度与临床结果无关。

结论
与安慰剂相比,维多利珠单抗诱导的粪便钙卫蛋白浓度降低更多。本项研究结果表明,虽然FC可能反映炎症状态,但vedolizumab诱导后的FC浓度可能不是粘膜炎症可靠生物标志物。

BMC Gastroenterology: 中国三级医院溃疡性结肠炎患者艰难梭菌感染的回顾性分析

有文献报道艰难梭菌感染(CDI)对溃疡性结肠炎(UC)患者的影响越来越大。因此,研究人员进行了一项回顾性研究,以确定UC患者CDI的发生率,临床特征,危险因素和预后情况。

GUT: 硫嘌呤对溃疡性结肠炎的自然病史和手术结果的影响

硫唑嘌呤肠被用作溃疡性结肠炎(UC)的维持治疗药物,但是这些药物是否影响该疾病的自然病史尚不清楚。本项研究的目的是评估10年内硫嘌呤在治疗溃疡性结肠炎中对于结肠切除术,住院,疾病程度进展和抗肿瘤坏死因子(TNF)治疗方面的效果。

JCC: Vedolizumab可以在中度至重度活动性溃疡性结肠炎患者取得很好的深度缓解

本项研究主要评估了vedolizumab在溃疡性结肠炎患者中诱导深度缓解的效果以及vedolizumab谷浓度与深度缓解率之间的相关性。

IBD:治疗干预对梅奥内镜评分为1的溃疡性结肠炎的患者具有延长复发的疗效

目前,粘膜愈合(MH)被普遍接受作为溃疡性结肠炎(UC)的治疗终点。最近的研究表明,Mayo内镜评分(MES)为1的患者的临床复发率高于MES为0的患者。因此,本项研究旨在证明二者之间的关系。

BMC Gastroenterology: 结肠微生物群在溃疡性结肠炎发病机制中的作用

最近有研究发现,肠道微生物群与UC的发病密切相关。目前,关于肠道微生物群的研究主要包括从肠腔收集的样本。然而,管腔菌群只是肠道微生物群的一部分,目前还缺乏对病理条件下粘膜菌群变化的研究。在这项研究中,研究人员调查了UC的发病与不同肠层的菌群变化之间的相关性。

AP&T: Vedolizumab血清浓度与溃疡性结肠炎的临床结果之间的关系

维多珠单抗(Vedolizumab)在治疗溃疡性结肠炎中前景广阔,治疗效果优良。但是目前缺乏前瞻性设计来评估维多珠单抗暴露浓度与疗效反应之间的研究。因此本项研究的主要目的是(a)调整潜在混杂变量后调查维多珠单抗暴露 - 反应关系; (b)提出潜在的目标血清维多珠单抗浓度用于未来的研究; (c)确定早期维多珠单抗血清浓度是否溃疡性结肠炎短期和长期临床结果相关。
