Currently, there is no consensus on how to score Crohn disease (CD) activity assessed by intestinal ultrasound (IUS) in children. This study aimed to design an easy-to-use IUS score for disease activity in pediatric CD.
Children undergoing ileo-colonoscopy for CD assessment underwent IUS the day before ileo-colonoscopy, assessed with simple endoscopic score for CD (SES-CD). IUS features were compared to the SES-CD on segmental level. Multiple regression analyses, separately for terminal ileum (TI) and colon, were done to assess predictors of disease activity and to develop a model.
In 74 CD patients (median 15 years, 48% female), 67 TI and 364 colon segments were assessed. Based on receiver operating characteristics curves, bowel wall thickness (BWT) was categorized into low [1 point: 2-3 mm (TI) and 1.6-2 mm (colon)], medium [2 points: 3.0-3.7 mm (TI) and 2.0-2.7 mm (colon)], and high [3 points: >3.7 mm (TI) and >2.7 mm (colon)]. In TI, only BWT was retained in the model [high BWT: odds ratio (OR) 11.50, P < 0.001]. In colon, BWT (high BWT: OR 8.63, P < 0.001) and mesenteric fat (1 point: OR 3.02, P < 0.001) were independent predictors. A pediatric Crohn disease IUS score (PCD-US) cut-off of 1 resulted in a sensitivity of 82% (95% confidence interval, CI: 65%-93%) and 85% (95% CI: 80%-89%) and a cut-off of 3 in a specificity of 88% (72%-97%) and 92% (87%-96%) for TI and colon, respectively. Inter-observer agreement was moderate for TI and colon ( K : 0.42, K : 0.49, respectively).
The PCD-US score is an easy-to-use and reliable score to detect or rule out CD activity on segmental level in children. External validation is needed before applying this score in clinical practice.
目前,对于儿童肠超声(IUS)评估克罗恩病(CD)活动,尚无共识如何评分。本研究旨在设计一种简单易用的儿童 CD 疾病活动 IUS 评分。
接受回结肠镜检查评估 CD 的患儿,在回结肠镜检查前一天进行 IUS 检查,采用简单内镜 CD 评分(SES-CD)进行评估。在节段水平上比较 IUS 特征与 SES-CD。分别对回肠末端(TI)和结肠进行多元回归分析,以评估疾病活动的预测因子并建立模型。
在 74 例 CD 患儿(中位数年龄 15 岁,48%为女性)中,评估了 67 个 TI 段和 364 个结肠段。根据受试者工作特征曲线,肠壁厚度(BWT)分为低 [1 分:2-3mm(TI)和 1.6-2mm(结肠)]、中 [2 分:3.0-3.7mm(TI)和 2.0-2.7mm(结肠)] 和高 [3 分:>3.7mm(TI)和>2.7mm(结肠)]。在 TI 中,只有 BWT 保留在模型中[高 BWT:比值比(OR)11.50,P<0.001]。在结肠中,BWT(高 BWT:OR 8.63,P<0.001)和肠系膜脂肪(1 分:OR 3.02,P<0.001)是独立的预测因子。PCD-US 评分的截断值为 1 时,TI 和结肠的敏感性分别为 82%(95%置信区间,CI:65%-93%)和 85%(95%CI:80%-89%),截断值为 3 时,特异性分别为 88%(72%-97%)和 92%(87%-96%)。TI 和结肠的观察者间一致性为中度( K :0.42, K :0.49)。
PCD-US 评分是一种简单易用且可靠的评分方法,可用于检测或排除儿童节段性 CD 活动。在将该评分应用于临床实践之前,需要进行外部验证。
