We aimed to clarify the relationship between plasma-free amino acid (PFAA) profiles and the Crohn's disease (CD) activity index (CDAI) in patients with CD.
We measured fasting PFAA concentrations in 29 patients with CD and their correlation with disease activity.
In all patients, significant correlations were noted between CDAI and concentrations of valine, methionine, leucine, histidine, tryptophan, alanine, tyrosine, total amino acids (TAAs), nonessential amino acids (NEAAs), essential amino acids (EAAs), and branched-chain amino acids (BCAAs). In patients with the ileo-colonic type of CD, significant correlations were noted between CDAI and valine, histidine, tryptophan, glutamine, TAA, NEAA, EAA, and BCAA. In ileal type, significant correlations were observed between CDAI and threonine, valine, histidine, serine, and glycine. In colonic type, significant correlations were noted between CDAI and valine, histidine, tryptophan, TAA, NEAA, EAA, and BCAA.
In patients with CD, plasma amino acids appear to be associated with disease activity.
我们旨在阐明克罗恩病（CD）患者血浆游离氨基酸（PFAA）谱与CD活动指数（CDAI）之间的关系。
我们测量了29例CD患者的空腹PFAA浓度及其与疾病活动的相关性。
在所有患者中，CDAI与缬氨酸、蛋氨酸、亮氨酸、组氨酸、色氨酸、丙氨酸、酪氨酸、总氨基酸（TAA）、非必需氨基酸（NEAA）、必需氨基酸（EAA）和支链氨基酸（BCAA）的浓度之间存在显著相关性。在回结肠型CD患者中，CDAI与缬氨酸、组氨酸、色氨酸、谷氨酰胺、TAA、NEAA、EAA和BCAA之间存在显著相关性。在回肠型中，CDAI与苏氨酸、缬氨酸、组氨酸、丝氨酸和甘氨酸之间存在显著相关性。在结肠型中，CDAI与缬氨酸、组氨酸、色氨酸、TAA、NEAA、EAA和BCAA之间存在显著相关性。
在CD患者中，血浆氨基酸似乎与疾病活动有关。
