The esophageal biopsy “pull” sign: a highly specific and treatment-responsive endoscopic finding in eosinophilic esophagitis (with video)
Esophageal biopsies in patients with eosinophilic esophagitis (EoE) can feel firm, with resistance appreciated when pulling the forceps to obtain the tissue sample. We aimed to assess the diagnostic utility of the esophageal biopsy pull sign, and determine its histologic associations and response to treatment
Accuracy of the Eosinophilic Esophagitis Endoscopic Reference Score in Diagnosis and Determining Response to Treatment
Little is known about the diagnostic utility of the eosinophilic esophagitis (EoE) endoscopic reference score (EREFS), and how scores change in response to treatment. We investigated the operating characteristics of the EREFS in diagnosis of EoE, how the score changes with treatment, and ways to optimize scoring system
A Gene Expression Panel is Accurate for Diagnosis and Monitoring Treatment of Eosinophilic Esophagitis in Adults
Eosinophilic esophagitis (EoE) can be difficult to diagnose. We aimed to evaluate whether a gene expression score could differentiate adult EoE cases from non-EoE controls and to determine whether scores normalized after treatment for EoE
Association Between Body Mass Index and Clinical and Endoscopic Features of Eosinophilic Esophagitis
Because eosinophilic esophagitis (EoE) causes dysphagia, esophageal narrowing, and strictures, it could result in low body mass index (BMI), but there are few data assessing this
Utility of a Noninvasive Serum Biomarker Panel for Diagnosis and Monitoring of Eosinophilic Esophagitis: A Prospective Study
Non-invasive biomarkers would be valuable for diagnosis and monitoring of eosinophilic esophagitis (EoE). The aim of this study was to determine the utility of a panel of serum biomarkers for the diagnosis and management of EoE
A Clinical Prediction Tool Identifies Cases of Eosinophilic Esophagitis Without Endoscopic Biopsy: A Prospective Study
Eosinophilic esophagitis (EoE) is difficult to distinguish from gastroesophageal reflux (GERD) and other causes of dysphagia. We assessed the utility of a set of clinical and endoscopic features for predicting EoE without obtaining esophageal biopsies
Accuracy of the Eosinophilic Esophagitis Endoscopic Reference Score in Diagnosis and Determining Response to Treatment
BACKGROUND & AIMS: Little is known about the diagnostic utility of the eosinophilic esophagitis (EoE) endoscopic reference score (EREFS), and how scores change in response to treatment. We investigated the operating characteristics of the EREFS in diagnosis of EoE, how the score changes with treatment, and ways to optimize scoring system. METHODS: We performed a prospective study of adults undergoing outpatient upper endoscopy from August 2011 through December 2013 at the North Carolina School of Medicine. Incident cases of EoE were diagnosed per consensus guidelines and were treated with topical steroids or dietary elimination (n=67); 144 subjects without EoE were included as controls. EREFS scores were compared between cases and controls. For EoE cases, scores were compared before and after treatment. Area under the receiver operator characteristic curve (AUC) analysis was used to determine diagnostic utility of the EREFS system. An iterative analysis was performed to determine optimal EREFS scoring weights. RESULTS: The mean total EREFS score was 3.88 for EoE cases and 0.42 for controls (P>.001); the score identified subjects with EoE with an AUC of 0.934. After treatment of EoE cases, the mean score decreased from 3.88 to 2.01 (P>.001). This change was more prominent for patients with a histologic response (reduction to <15 eos/hpf), compared with non-responders; post-treatment scores were 0.45 for responders vs 3.24 for non-responders (P<.001). A weighted scoring system that doubled exudates, rings, and edema scores maximized the responsiveness of the total EREFS score. CONCLUSIONS: The EREFS classification system identifies patients with EoE an AUC of 0.934; the score decreases with treatment, and histologic responders have significantly lower scores than non-responders. This system can therefore be used to identify individuals with EoE and used as an endoscopic outcome measure to follow their response to treatment
