概括
后生物ReFerm®可以通过改善肠道屏障功能来减少酒精相关肝病患者的肝纤维化. 这项研究发现减少纤维化标志物的潜在益处,没有报告严重不良事件.
科学领域:
- 胃肠病学和肝病学
- 微生物组研究 微生物组研究
- 营养科学 营养科学
背景情况:
- 肠道屏障功能受损与与酒精有关的肝病 (ARLD) 肝纤维化进展有关.
- 后生物制剂,如ReFerm®,在调节肠道屏障透性方面显示出潜力.
- 准肠道健康可能为ARLD提供一种新的治疗策略.
研究的目的:
- 评估后生物 ReFerm® 降低晚期,补偿性 ARLD 患者肝纤维化进展的疗效.
- 评估ReFerm®对纤维化形成标志物α-平滑肌肉活性蛋白 (α-SMA) 的影响.
- 确定ReFerm®在该患者群体中的安全性.
主要方法:
- 一个开放的,单中心的随机对照试验,涉及56名患有先进的,补偿的ARLD的患者.
- 参与者被随机分配1:1接受ReFerm® (n=28) 或标准营养支持 (Fresubin®,n=28) 24周.
- 肝脏活检在干预前和后进行了分析,以通过盲目的病理学家使用自动化数字成像来减少α-SMA.
主要成果:
- 对于40名参与者,可提供配对肝活检 (ReFerm®: n=21;Fresubin®: n=19).
- 在接受ReFerm®的29%患者中,观察到≥10%的α-SMA减少,而接受Fresubin®的患者则为14% (OR=2.40;p=0.200).
- 在试验期间,没有报告与治疗相关的严重不良事件.
结论:
- 补充ReFerm®表明有可能减少ARLD患者的肝纤维化,可能是通过增强肠道屏障功能.
- 这些发现需要在更大规模的安慰剂对照试验中进一步调查,以确认ReFerm®在ARLD中的治疗潜力.
- 对于患有晚期,补偿性ARLD的患者来说,ReFerm®似乎是一种安全的干预措施.

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
