Clin Exp Immunol:粪便B细胞活化因子对肠道炎症的诊断价值

2020-07-02 MedSci原创 MedSci原创

粪便钙蛋白作为炎症性肠道疾病(IBD)的敏感生物标志物已成功被广泛推荐。最近,我们发现了一种优秀的新型粪便生物标志物--B细胞活化因子(BAFF),与粪便钙蛋白一样有效地诊断肠道炎症。

粪便钙蛋白作为炎症性肠道疾病(IBD)的敏感生物标志物已成功被广泛推荐。最近,我们发现了一种优秀的新型粪便生物标志物--B细胞活化因子(BAFF),与粪便钙蛋白一样有效地诊断肠道炎症。

 

本研究前瞻性地纳入了230例腹部不适的患者,并在内镜检查前24 h内采集粪便样本。结果显示,溃疡性结肠炎(中位数=1549pg/g,P<0-0001)、克罗恩病(中位数=735pg/g,P<0-0001)、胃癌(中位数=267pg/g,P<0-0001)和结直肠癌(中位数=533pg/g,P < 0-0001)患者的粪便BAFF水平显著高于健康组(中位数=61 pg/g),而胃息肉、结直肠息肉、食管炎/胃炎/十二指肠炎和消化性溃疡患者的数值则在健康人的范围内(P > 0-05)。最佳截止值为219-5 pg/g的粪便BAFF对IBD或癌的敏感性、特异性、阳性预测值和阴性预测值分别为85%、91%、84%和92%。

 

因此,该结果表明,粪便BAFF作为IBD和胃肠癌的敏感筛查参数具有潜在的作用,也是选择腹部不适患者进行进一步内镜检查的有用工具。
