ABSTRACT

Objective

There is a growing need for biomarkers to predict therapeutic outcome in Crohn’s disease (CD).

Main outcome measures

The aim was to evaluate whether NLR (neutrophil-to-lymphocyte ratio), PLR (platelet-to-lymphocyte ratio), ELR (eosinophil-to-lymphocyte ratio), and ENLR (eosinophil*neutrophil-to-lymphocyte ratio), could be prognostic biomarkers of endoscopic response (ER) when starting biologics.

Research design and methods

Patients with CD who started biologics were enrolled. Multivariate analysis was used to evaluate whether NLR, PLR, ELR and ENLR at baseline and at w12 could predict ER (Simple Endoscopic Score for Crohn’s disease [SES-CD] ≤2 or SES-CD≤2 and Rutgeerts i0-i1) after 52 weeks of treatment. Area under the curve (AUC) was calculated to find the cutoffs.

Results

107 patients were included. Patients who achieved ER had significantly lower baseline NLR (p = 0.025), ELR (p = 0.013), and ENLR (p = 0.020) compared with those without ER; results after 12 weeks of treatment for ELR (p = 0.006) and ENLR (p = 0.003). AUC was 0.64 (p = 0.003), 0.67 (p = 0.006) and 0.65 (p = 0.014) for NLR, ELR and ENLR.

Conclusions

Low NLR, ELR and ENLR can predict ER and could be used in clinical practice for a better management of CD patients.

克罗恩病患者基于血液的预后生物标志物生物制剂:预测内窥镜结果的有前途的工具

摘要

客观的

越来越需要生物标志物来预测克罗恩病 (CD) 的治疗结果。

主要观察指标

目的是评估 NLR(中性粒细胞与淋巴细胞的比率)、PLR(血小板与淋巴细胞的比率)、ELR(嗜酸性粒细胞与淋巴细胞的比率)和 ENLR(嗜酸性粒细胞*中性粒细胞与淋巴细胞的比率)是否可以成为开始使用生物制剂时内镜反应 (ER) 的预后生物标志物。

研究设计与方法

招募了开始使用生物制剂的 CD 患者。多变量分析用于评估 NLR、PLR、ELR 和 ENLR 在基线和 w12 是否可以预测 52 岁后的 ER(克罗恩病简单内镜评分 [SES-CD] ≤2 或 SES-CD≤2 和 Rutgeerts i0-i1)数周的治疗。计算曲线下面积 (AUC) 以找到截止值。

结果

包括 107 名患者。与没有 ER 的患者相比,获得 ER 的患者的基线 NLR (p = 0.025)、ELR (p = 0.013) 和 ENLR (p = 0.020) 显着降低;ELR (p = 0.006) 和 ENLR (p = 0.003) 治疗 12 周后的结果。NLR、ELR 和 ENLR 的 AUC 分别为 0.64 (p = 0.003)、0.67 (p = 0.006) 和 0.65 (p = 0.014)。

结论

低 NLR、ELR 和 ENLR 可以预测 ER,可用于临床实践以更好地管理 CD 患者。
