避免肠道纤维狭窄并发症的发生是克罗恩病(CD)管理中最重要的治疗考量,因此,本项研究旨在研究纤维化候选生物标志物与纤维狭窄CD的未来发展的关联。

背景及目的:
避免肠道纤维狭窄并发症的发生是克罗恩病(CD)管理中最重要的治疗考量,因此,本项研究旨在研究纤维化候选生物标志物与纤维狭窄CD的未来发展的关联。

方法:
研究人员使用风险分层和克罗恩病队列儿童快速疾病进展的免疫遗传和微生物标记,来预测肠道发生纤维化狭窄的情况发生,即诊断时具有炎症表型(B1)的受试者,后来转变为狭窄表型( B2)在3年内与那些保持B1的人进行了比较。诊断时收集的血清进行了平行反应监测靶向蛋白质组学分析和常规酶联免疫吸附测定,Cox比例风险回归用于时间依赖性结果的多变量分析。

结果:
在116名受试者中,有58名在诊断时确诊为B1表型,后来转为B2型,另外58名在随访3年后仍为B1型。上四分位数的细胞外基质蛋白1(ECM1)水平(风险比[HR] 3.43,95%置信区间[CI] 1.33,8.42)与未来的纤维狭窄疾病相关。ASCA IgA(HR 4.99,95%CI 1.50,16.68)和CBir水平(HR 5.19,95%CI 1.83,14.74)也与未来的肠纤维狭窄相关。

结论:
ECM1和纤维化的其他生物标志物可能有助于确定CD患儿无并发症炎症转变为B2狭窄表型的风险。

J Gastroenterol Hepatol:血清WFA(+) -M2BP或IV型胶原7S水平可作为检测肝纤维化的有效独立标志物

研究结果表明,血清WFA(+) -M2BP或IV型胶原7S水平可作为检测肝纤维化的有效独立标志物,而WFA(+) -M2BP和IV型胶原7S均可提高诊断肝纤维化的敏感性和阴性预测值。这些结果需要在多个临床中心的更大人群中得到验证。

Jgastroenterology:血清醛酮还原酶家族1成员B10可以预测晚期肝纤维化和非酒精性脂肪性肝炎的致命并发症

非酒精性脂肪性肝炎(NASH)在晚期可以进展为肝纤维化,以及肝细胞癌(HCC)和门静脉高压症,因此是一种很严重的疾病。尽管通过活组织检查可以准确诊断肝纤维化,但优选非侵入性方法。Aldo-keto还原酶家族1成员B10(AKR1B10)与HCC相关,并且它是通过溶酶体介导的非经典途径由肝细胞分泌到血液中。因此,本项研究旨在分析AKR1B10蛋白的分泌是否与晚期NASH相关。
