Filter by:The purpose of the study is to investigate if serological parameters such as "extracellular Serum-Tryptase (ST)" and "eosinophilic cationic protein (ECP)" are useful for the diagnosis and surveillance of the eosinophilic esophagitis (EE).
This study is being done to collect data on the potential use of the cytosponge as non-invasive tool in evaluating patients with eosinophilic esophagitis.
This purpose of this study is the long-term follow-up of glucocorticosteroid-related adverse events and hypothalamic-pituitary-adrenal axis (HPA) suppression in subjects after discontinuation of study drug received in the PR-021 study (Safety and Tolerability Study of Oral EUR-1100 to Treat Eosinophilic Esophagitis). The study will also provide the opportunity to better understand the natural course of eosinophilic esophagitis and define the treatment modalities of eosinophilic esophagitis with EUR-1100, such as the need for chronic maintenance or intermittent treatment. All subjects who complete PR-021 will be offered the opportunity to participate in this study. The duration of this follow-up study is six months, during which subjects will visit the clinic for safety evaluation and clinical symptom assessment at the screening, Week 8, Week 16, and Week 24 visits. Additional phone visits will occur at Week 4, Week 12, and Week 20.
The investigators will determine the prevalence of gastroesophageal reflux disease (GERD) in Eosinophilic Esophagitis (EoE) and importantly determine the predictors of response to Proton Pump Inhibitor (PPI) therapy in EoE. Moreover, the investigators will determine the effect of GERD on the location of esophageal eosinophilia.
Eosinophilic Esophagitis (EE) is a condition where eosinophils (a cell that fights infection) travel to the esophagus (the tube through which food passes to the stomach). These cells do not belong there and can cause pain, soreness, difficulty swallowing and sometimes vomiting. Ways to treat this condition include medicine, not eating some foods, and drinking a specific formula (like milk) without eating any other foods. Doing these things can help fight off EE but these problems can come back when treatment is stopped. If EE symptoms go on for a long time, it can lead to the esophagus becoming narrow and feeling tight when eating and swallowing and surgery may be needed to widen the narrowed area to relieve the sensation of tightening. Montelukast is a medicine that fights off a type of chemical that can be a magnet for eosinophils. People usually take this medicine to help treat their asthma. It is not approved to treat EE. This medication is taken once a day. The purpose of this study is to see if Montelukast, compared to placebo, will help reduce the number of eosinophils in children with EE and help stop the tightening of the esophagus.
Background: Up to 40% of patients who are treated with PPIs for symptoms that are thought to be due to GERD experience only incomplete relief of their symptoms. Those patients are deemed "PPI failures." Esophageal pH monitoring studies have shown that PPI failure rarely is due to persistent acid reflux. Recently, heartburn that is refractory to treatment with PPIs has been described in patients with eosinophilic esophagitis, a disorder of unknown etiology in which eosinophils infiltrate the squamous epithelium of the esophagus, where they cause symptoms and tissue injury. Presently, it is not clear how often eosinophilic esophagitis underlies PPI failure for patients with GERD symptoms. Purpose: To estimate the frequency with which eosinophilic esophagitis is the cause of "PPI failure" in patients thought to have heartburn due to GERD. Methods: Patients referred to the Division of Gastroenterology at the Dallas VA Medical Center for the evaluation of heartburn that is refractory to PPI therapy will be invited to participate in the study. Patients who provide informed consent will have a medical history taken. Women of child bearing potential will have a pregnancy test. The patients' current PPI therapy will be discontinued, and patients will be treated with lansoprazole 30 mg BID for one week. The patient will return to the clinic one week later. Patients who feel that their heartburn has not improved by more than 50% from baseline will have an endoscopic evaluation. During the endoscopic examination, biopsy specimens will be taken as follows: A. Two specimens from the proximal esophagus at 20 cm from the incisor teeth. B. Two specimens from the mid-esophagus at 28 cm from the incisor teeth. C. Two specimens from the distal esophagus, 3 cm above the squamo-columnar junction. D. Two specimens from the distal esophagus, 1 cm above the squamo-columnar junction. E. Two specimens from the second portion of the duodenum (to see if the eosinophilia is confined to the esophagus, or part of a more extensive eosinophilic gastroenteritis). A diagnosis of eosinophilic esophagitis will be made if there is at least one high-power field with >25 eosinophils, or two or more high-power fields with >15 eosinophils. Potential Benefits: This study will provide an estimate on the frequency with which eosinophilic esophagitis is the cause of "PPI failure" in patients thought to have heartburn due to GERD. This has substantial potential importance for patient management.
Eosinophilic esophagitis (EoE) is an inflammatory disease of the esophagus, characterized by eosinophilic infiltration and gastrointestinal (GI) symptoms. There are no pharmacological treatments for EoE approved by the US Food and Drug Administration (FDA). Supported by published case series and controlled trials in children and adults, the most widely used drug treatment for EoE is off-label use of corticosteroids intended for local (esophageal mucosal) action. This study will evaluate the safety and tolerability of orally administered EUR-1100 once or twice daily. Eligible subjects will be randomized into one of the 3 treatment groups. The Treatment Period will be 8 weeks during which subjects will visit the clinic at the screening visit, randomization, week 4, 8 and 1 week after end of treatment for clinical symptom assessment and safety evaluation. Additional phone visits will occur at week 2 and week 6.
Develop Registry tool
This study will establish a registry for participants with eosinophilic esophagitis (EoE) and create a research resource that will provide further insights into EoE.
Confocal laser endomicroscopy enables in vivo microscopic imaging within the mucosa layer of the gut at a subcellular resolution. Various studies have addressed the potential of endomicroscopy for the in vivo diagnosis of esophageal squamous cell carcinoma, Barrett´s esophagus and esophageal adenocarcinoma. Currently, there is only one case report from our group who noted the utility of endomicroscopy for the in vivo diagnosis of eosinophilic esophagitis. The purpose of this study is to determine whether endomicroscopy is effective for the in vivo diagnosis of eosinophilic esophagitis.
