JCC:采用新的血清标记物来检测阿达木单抗治疗的患有溃疡性结肠炎的患者的粘膜愈合

2018-03-19 MedSci MedSci原创

临床工作中迫切需要准确检测溃疡性结肠炎(UC)患者粘膜愈合(MH)的替代标志物。英夫利昔单抗治疗后,粘膜愈合的生物学指标与基质金属蛋白酶-9(NGAL-MMP-9),C-反应蛋白(CRP)和嗜中性粒细胞计数与MH显着相关。我们研究了用阿达木单抗(ADM)治疗后这5种标志物是否也与MH相关。

背景:临床工作中迫切需要准确检测溃疡性结肠炎(UC)患者粘膜愈合(MH)的替代标志物。英夫利昔单抗治疗后,粘膜愈合的生物学指标与基质金属蛋白酶-9(NGAL-MMP-9),C-反应蛋白(CRP)和嗜中性粒细胞计数与MH显着相关。我们研究了用阿达木单抗(ADM)治疗后这4种标志物是否也与MH相关。

方法:在为期14(10-25)周的治疗后,从31名UC患者(58%女性,平均年龄35.6岁)获得血清样品。所有患者在治疗前都有内镜疾病活动(梅奥内镜下评分:MES≥2),并且MH在随访内镜时定义为MES≤1。用ELISA测量NGAL-MMP-9,IL-37和CHI3L1。

结果:21名患者(68%)通过ADM治疗达到了粘膜愈合。与基线相比,MH患者的NGAL-MMP-9水平显着降低(96.9 vs. 214.1 ng / ml,p = 0.002),而无MH患者的NGAL-MMP-9水平无明显变化。MH患者中ADM治疗后中性粒细胞计数明显低于基线(3.6 vs. 6.5 × 109 / l,p = 0.023)。MH患者(15-1.1mg / l,p = 0.008)ADM后CRP水平显着降低,MH患者基线水平高于无MH患者(15 vs. 2.4mg / l,p = 0.004)。与基线相比,无ADM后患者的IL-37水平显着升高(29 vs. 19.3 ng / ml,p =0.034),MHAL-MMP-9(AUC = 0.70),嗜中性粒细胞计数(AUC = 0.58),CRP(AUC = 0.56),IL-37(AUC = 0.79)当所有标记物合并时,ADM显着增加(AUC = 0.86)。MH标记的5标记组具有75%的敏感性,89%的特异性,67%的阳性预测值和92%的阴性预测值。

结论:ADM治疗后,中性粒细胞相关标志物(NGAL-MMP-9,LL-37和CHI3L1)以及CRP和中性粒细胞计数与MH显着相关。这些数据与我们以前在英夫利昔单抗治疗的患者中的发现一致。因此,我们建议在用抗TNF治疗的UC患者中应该密切监测粘膜愈合。

背景:抗肿瘤坏死因子治疗在治疗患有肛周病变的克罗恩病患者中广泛运用,最近有研究表明患有肛瘘的患者需要更大剂量的英夫利西单抗治疗来达到治疗效果。方法:研究人员对那些行英夫利西单抗或者阿达木单抗的患者进行了一项回顾性调查研究,这些患者都存在肛周病变,瘘管闭合定义为无引流液流出或者核磁显像证实。结果:总共有352名患者接受了此项调查,67名患者患有肛瘘,其中47名接受了英夫利西单抗治疗,在瘘管闭合的患者
