IBD: 血清二肽基肽酶4可以作为炎症性肠病疾病活动和预后的预测指标

2020-01-29 不详 MedSci原创

血清二肽基肽酶4(DPP-4)作为炎症性肠病(IBD)的生物标记物目前引起了很多学者的兴趣,因为该蛋白酶可以使参与炎症级联反应的几种肽失活。因此,本项研究将对此进行相关研究。

背景
血清二肽基肽酶4(DPP-4)作为炎症性肠病(IBD)的生物标记物目前引起了很多学者的兴趣,因为该蛋白酶可以使参与炎症级联反应的几种肽失活。因此,本项研究将对此进行相关研究。

方法
研究人员使用临床指标评估了由195名患者组成的两个前瞻性队列(101名患有克罗恩病[CD],94名患有溃疡性结肠炎[UC]),并随访评估治疗的进展。在基线时有68例患者接受了内镜检查。在第二批46名经过生物学治疗的患者中,评估了治疗反应。在基线和随访期间对血清DPP-4,C反应蛋白(CRP)和粪便钙卫蛋白水平进行了定量分析。

结果
与缓解者相比,处于疾病活跃的IBD患者的中位DPP-4水平显着降低(CD:1043 [831–1412] vs 1589 [1255-1956] ng / mL;P <0.001; UC:1317 [1058-1718] vs 1798) [1329–2305] ng / mL;P = 0.001)和健康对照组(2175 [1875–3371] ng / mL)。实际上,DPP-4能够区分临床和内窥镜检查活动与缓解之间的关系,曲线下面积(AUC)为0.81 / 0.93(CD)和0.71 / 0.79(UC)。此外,DPP-4水平应答较高的治疗和UC之间更显着(1467 [1301至1641] VS 1211 [1011至1448] ng / mL; P <0.001)比CD患者(1385 [1185至1592]对1134 [975至1469] ng / mL;P = 0.015)。

结论
本项研究表明血清DPP-4可用作IBD活性和生物治疗反应的非侵入性生物标志物,并且可以作为治疗升级的预测指标。
