Abstract

Background/aims: Leucine-rich α-2-glycoprotein (LRG) is a new serum biomarker reflecting the disease activity of ulcerative colitis (UC), but its change during the acute phase has not been enough investigated.

Methods: Patients with UC who initiated the induction therapy with steroid or advanced therapy (biologics or Janus kinase inhibitors) were prospectively enrolled. Associations of LRG, C-reactive protein (CRP) and fecal calprotectin (FC) at baseline, week 1, and week 8 with clinical remission at week 8 and subsequent endoscopic improvement within 1 year (Mayo endoscopic subscore of 0 or 1) were assessed.

Results: A total of 143 patients with UC were included. LRG and CRP at week 1 were significantly lower in the clinical remission group than in the non-remission group (LRG, 20.6 μg/mL vs. 28.4 μg/mL, P< 0.001; CRP, 0.9 mg/dL vs. 2.3 mg/dL, P< 0.001) while FC demonstrated the difference between groups only at week 8. The area under the curves of week 1 LRG, CRP, and FC for week 8 clinical remission using the receiver operating characteristic curves analysis were 0.68, 0.71, and 0.57, respectively. Furthermore, LRG and CRP predicted subsequent endoscopic improvement as early as week 1, while FC was predictive only at week 8.

Conclusions: LRG can be an early-phase biomarker predicting subsequent clinical and endoscopic response to induction therapy.

血清富亮氨酸α-2-糖蛋白的早期变化可预测溃疡性结肠炎的临床和内窥镜反应。

背景/目的：富亮氨酸α-2-糖蛋白（LRG）是反映溃疡性结肠炎（UC）疾病活动性的一种新的血清生物标志物，但其在急性期的变化尚未得到充分研究：方法：前瞻性地招募了开始接受类固醇诱导治疗或晚期治疗（生物制剂或 Janus 激酶抑制剂）的 UC 患者。评估基线、第1周和第8周的LRG、C反应蛋白（CRP）和粪便钙蛋白（FC）与第8周临床缓解及随后1年内内镜改善（梅奥内镜子评分为0或1）的相关性：结果：共纳入 143 名 UC 患者。临床缓解组第1周的LRG和CRP明显低于未缓解组（LRG，20.6 μg/mL vs. 28.4 μg/mL，P< 0.001；CRP，0.9 mg/dL vs. 2.3 mg/dL，P< 0.001），而FC仅在第8周显示出组间差异。通过接收器操作特征曲线分析，第1周LRG、CRP和FC的曲线下面积对第8周临床缓解的预测分别为0.68、0.71和0.57。此外，LRG 和 CRP 早在第 1 周就能预测随后的内镜改善，而 FC 仅在第 8 周才能预测：结论：LRG可以作为一种早期生物标志物，预测诱导治疗的后续临床和内镜反应。

期刊介绍： Intestinal Research (Intest Res) is the joint official publication of the Asian Organization for Crohn''s and Colitis (AOCC), Chinese Society of IBD (CSIBD), Japanese Society for IBD (JSIBD), Korean Association for the Study of Intestinal Diseases (KASID), Taiwan Society of IBD (TSIBD) and Colitis Crohn''s Foundation (India) (CCF, india). The aim of the Journal is to provide broad and in-depth analysis of intestinal diseases, especially inflammatory bowel disease, which shows increasing tendency and significance. As a Journal specialized in clinical and translational research in gastroenterology, it encompasses multiple aspects of diseases originated from the small and large intestines. The Journal also seeks to propagate and exchange useful innovations, both in ideas and in practice, within the research community. As a mode of scholarly communication, it encourages scientific investigation through the rigorous peer-review system and constitutes a qualified and continual platform for sharing studies of researchers and practitioners. Specifically, the Journal presents up-to-date coverage of medical researches on the physiology, epidemiology, pathophysiology, clinical presentations, and therapeutic interventions of the intestinal diseases. General topics of interest include inflammatory bowel disease, colon and small intestine cancer or polyp, endoscopy, irritable bowel syndrome and other motility disorders, infectious enterocolitis, intestinal tuberculosis, and so forth. The Journal publishes diverse types of academic materials such as editorials, clinical and basic reviews, original articles, case reports, letters to the editor, brief communications, perspective, statement or commentary, and images that are useful to clinicians and researchers.
