Abstract

BACKGROUND AND AIMS

Exclusive enteral nutrition (EEN) induces clinical and mucosal healing (MH) in Crohn's disease (CD), with MH the best determinant of future outcome. We investigated efficacy of EEN for inducing early clinical, biochemical, mucosal and transmural remission of CD and related early endoscopic response to outcomes at 1 year.

METHODS

In a prospective, open label study 34 children (mean 13.1 years; 21 males) with new diagnosis CD were offered EEN, 26 completed a minimum 6 weeks EEN and underwent paired clinical, biochemical and endoscopic assessment at start and completion using PCDAI, BMI, CRP and Simple Endoscopic Score for CD (SES-CD). A subset, 16/26, had paired MR enterography scored. Early good endoscopic response (complete MH, or near complete, SES-CD 0-3) was related to outcome at 1 year.

RESULTS

EEN improved mean PCDAI (37.88-7.01, p < 0.001; BMI Z scores (-1.54 to -0.54, p < 0.01); weight Z score (-0.79 to -0.08, p < 0.03); CRP (44.86-5.5, p < 0.001); endoscopy (SES-CD 14.28-3.88, p < 0.001) and MRE (5.14-2.79, p = 0.01). Of 26 children, 22 (84 %) achieved clinical remission; 20 (76 %) biochemical remission. Fifteen (58 %) had early good endoscopic response (11 complete, 4 near complete MH) and 3/14 (21 %) had complete transmural remission of ileal CD (MRE-CD: 0-1). Early good endoscopic response was associated with reduced endoscopic confirmed relapse (53 vs. 100 %, p = 0.02), anti-TNF use (33 vs. 88 %, p = 0.01) and hospitalisation (40 vs. 88 %) at 1 year.

CONCLUSIONS

EEN is effective for inducing early clinical, biochemical, mucosal and transmural remission. Early endoscopic remission improves outcomes at 1 year.

摘要

背景与目的

肠内营养(EEN)可诱导克罗恩病(CD)的临床和黏膜愈合(MH),而 MH 是未来结局的最佳预测指标。我们研究了 EEN 诱导 CD 早期临床、生化、黏膜和黏膜下缓解的疗效,并探讨了早期内镜反应与 1 年结局的关系。

方法

在一项前瞻性、开放标签的研究中,34 名新诊断为 CD 的儿童(平均年龄 13.1 岁;21 名男性)接受 EEN 治疗,其中 26 名完成了至少 6 周的 EEN,并在开始和结束时使用 PCDAI、BMI、CRP 和简单 CD 内镜评分(SES-CD)进行临床、生化和内镜评估。其中 16/26 名患者进行了配对的磁共振肠造影术评分。早期内镜缓解(完全 MH 或接近完全缓解,SES-CD 0-3)与 1 年的结局相关。

结果

EEN 显著改善了 PCDAI(37.88-7.01,p<0.001;BMI Z 评分(-1.54 至-0.54,p<0.01);体重 Z 评分(-0.79 至-0.08,p<0.03);CRP(44.86-5.5,p<0.001);内镜检查(SES-CD 14.28-3.88,p<0.001)和 MRE(5.14-2.79,p=0.01)。在 26 名儿童中,22 名(84%)达到临床缓解;20 名(76%)达到生化缓解。15 名(58%)患儿早期内镜缓解良好(11 名完全缓解,4 名接近完全 MH),14 名患儿回肠 CD 的完全黏膜下缓解(MRE-CD:0-1)。早期内镜缓解与内镜确认的复发率降低相关(53%比 100%,p=0.02),抗 TNF 使用率降低(33%比 88%,p=0.01),住院率降低(40%比 88%,p=0.02)。

结论

EEN 可有效诱导 CD 早期临床、生化、黏膜和黏膜下缓解。早期内镜缓解可改善 1 年结局。
