Gastroenterology:色氨酸代谢增加与炎症性肠病的活性有关

2017-12-22 MedSci MedSci原创

色氨酸及其一些代谢物改变降低了小鼠结肠炎的严重程度,而从饮食中去除色氨酸则会增加患结肠炎的易感性。本项研究旨在系统地评估血清炎症性肠病(IBD)患者的色氨酸及其代谢物水平,并研究其与临床和血清学特征的关系。

背景:色氨酸及其一些代谢物改变降低了小鼠结肠炎的严重程度,而从饮食中去除色氨酸则会增加患结肠炎的易感性。本项研究旨在系统地评估血清炎症性肠病IBD)患者的色氨酸及其代谢物水平,并研究其与临床和血清学特征的关系。

方法:研究人员研究了535例IBD患者(211例溃疡性结肠炎[UC],234例克罗恩病[CD]; 236例男性),2013年8月至2014年4月在德国就诊且随访至2016年7月的患者。匹配了291例正常对照组; 使用高效液相色谱法测量色氨酸的水平。在148名患者和100名对照的血清中通过质谱法测量了色氨酸的代谢物。从临床活性期的UC(n = 10)或CD(n = 8)的患者收集成对的粪便和血清样品,以研究血清色氨酸水平和粪便微生物群的组成之间的关联。我们使用实时聚合酶链式反应来测量60名UC患者,50名CD患者和30名对照者的结肠活检中的信使RNA水平。

结果:色氨酸的血清水平在IBD患者中相比于对照组显着降低(P  = 5.3×10 -6)。研究人员发现血清中色氨酸水平与疾病活性或C-反应蛋白水平呈负相关。与对照组相比,来自IBD患者的结肠活检显着降低了编码色氨酸2,3-双加氧酶-2和溶质载体家族6成员19(也称为B0AT1)的信使RNA的水平,而编码吲哚胺2,3-双加氧酶-1则显着增加。粪便微生物群的组成与血清色氨酸水平有关。

结论:在对来自500多名IBD患者的血清样品的分析中,我们观察到血清色氨酸水平与疾病活性之间呈负相关。色氨酸代谢物(特别是喹啉酸)的水平增加表明活性IBD患者色氨酸降解活性高。色氨酸缺乏可能导致IBD的发展或加重疾病活动。同时也告诉我们,需要介入性临床研究来确定肠色氨酸途径的改变是否影响IBD的严重程度。
