Active clinical trials for "Esophagitis"

In the past years, the adenocarcinoma of the esophagogastric junction (AEG) has been increasing obviously in China. It may be caused by the reason of increased body weight, alcohol consumption, gastroesophageal reflux disease and premalignant. In western countries, the 5-year rate of advanced AEG was less than 30%, it was the same in China. There was significant difference in epidemiology, pathogenic mechanism, biological characteristics and prognosis between AEG and antrum tumors, so AEG was regarded as a kind of independent disease. Up till now, the scope of lymph node dissected, the selection of operation approach, the resection range and the digestive tract reconstruction for the treatment of AEG were in dispute, especially in the reconstruction of digestive tract after operation. The purpose of this study is to investigate the efficacy and safety of the proximal gastrectomy combined with Giraffe anastomosis for early adenocarcinoma of esophagogastric junction.

This will be a Phase I, randomized, double-blind, positive- and placebo-controlled study to evaluate the safety, tolerability, and PK/PD of multiple oral doses of H008 in healthy adult subjects. Two dose levels of H008 at 20 mg and 40 mg will be studied in two sequential cohorts. Each cohort will be enrolled with 12 subjects (8 on H008, 2 on placebo and 2 on positive control drug). Subjects are only allowed to participate in one of the two cohorts. Both the investigational product and placebo will be given in a double blinded manner, while the positive control drug will be given in an open-label manner.Dose escalation to the next cohort will be permitted only when safety data until follow-up and PK data until 48 hours post-last dose, from all subjects in previous cohorts are reviewed, and the investigational product is deemed well tolerated. The study will consist of a screening period, a baseline period, a 7-day repeated-dose period and a safety follow-up period.

The investigators conducted this phase II study of EGCG therapy protection of the esophagus from damage induced by radiotherapy. In order to observe the effectiveness of EGCG, esophageal toxicity was recorded weekly using a grading scale based on symptomatology, following the Radiation Therapy Oncology Group (RTOG) scoring system. Patient-reported pain related to esophagitis was measured using the numerical rating scale (NRS) every week from EGCG application to 2 weeks after the end of radiotherapy. The scales are translated into Chinese and guides in Chinese are developed instructing how to use the scales and perform the assessments.

Can an MRI detect and monitor the inflammatory and fibrotic possess in patients with Eosinophilic Esophagitis

Background: - Food allergies are characterized by abnormal immune system responses to certain foods, such as peanuts, strawberries, and shellfish. Some individuals with these allergies have immediate allergic reactions on contact with the food in question and need immediate treatment to prevent severe complications. In contrast, eosinophil-associated gastrointestinal disorders are related disorders in which white blood cells in the intestinal tract react to certain foods, causing abdominal pain, nausea, and other digestion problems. Researchers are interested in studying these conditions to better understand how the immune system responds to food allergies. Objectives: To examine how the immune system responds to food allergens. To examine how certain white blood cells contribute to disease in individuals with food allergies and other inflammatory diseases. Eligibility: Individuals between 18 and 65 years of age who have a history of (a) severe allergic reaction to peanuts (and have peanut-specific antibodies), (b) allergy or inflammatory disease, or (c) eosinophil-associated gastrointestinal disorder (with at least two documented food allergies). Healthy volunteers between 18 and 65 years of age who have no known allergies or asthma. Design: All participants will have a screening visit and a procedure visit. The procedure visit will take place within 30 to 60 days of the screening visit, and will take 3 to 4 hours depending on the procedure(s) done. Participants will be screened with a physical examination and medical history, and will provide blood samples for testing. Participants with peanut or other allergies will have additional tests to determine their levels of sensitivity to certain foods. Participants with eosinophil-associated gastrointestinal disorder will provide stool samples for testing. At the procedure visit, participants with peanut allergies and participants with other allergies will provide blood samples and have leukapherisis to collect white blood cells for examination. At the procedure visit, healthy volunteers and participants with eosinophil-associated gastrointestinal disorder will provide blood samples and have leukapherisis to collect white blood cells for examination. In addition, some but not all of these participants will have a procedure called esophagogastroduodenoscopy (EGD), which will examine the esophagus, stomach, and small intestine. Participants who are scheduled to have EGD will be asked to fast for 6 hours before the procedure.

In a related study, the investigators have found evidence that patients with Barrett's esophagus have a leak for oral sucrose to leave their upper gastrointestinal tract, enter the blood, and be filtered into urine. The amount of sucrose appearing in an overnight urine sample can be used to indicate the presence of Barrett's esophagus and/or esophagitis in a patient reporting with reflux (GERD) symptoms. The leak is presumably in the Barrett's epithelium itself. This phenomenon will be used to test if a standard 8 week therapy of Nexium in a first-time-presenting GERD patient can reduce the leak as a means of assessing the efficacy of the drug in that patient. The investigators predict that Nexium will reduce leak in esophagitis but not Barrett's patients.

Do patients with eosinophilic esophagitis have baseline increased esophageal mucosal impedance? And will treatment that reverses esophageal eosinophilia in patients, correct abnormalities in mucosal impedance?

Endoscopy is a widely used modality for the diagnosis and classification of Gastroesophageal reflux disease (GERD), and the extent of esophageal mucosal breaks on endoscopy can be assessed. However, there were some limitation in diagnosis of GERD using endoscopy More than half of patients with GERD reveal no visible abnormality on conventional endoscopy, it is possible that minute mucosal changes are underestimated by conventional endoscopy due to the limitation of visual ability In addition of uncertainty in detecting mucosal breaks, uncertainty in describing severity of mucosal injury can lead to inconsistency among interpreters. Interobserver agreement regarding diagnosis and classification of GERD using endoscopy is unsatisfactory to apply daily practice. Thus, the development of a new method to define the intra-esophageal injury for use in daily practice is a worthwhile endeavor and developed, such as narrow-band imaging (NBI), Fuji Intelligent Chromoen-doscopy (FICE) and i-scan. Among them, i-scan technology is the most recently developed image enhancing technology, which consists of three modes of image enhancement, i.e. surface enhancement (SE), contrast enhancement (CE), and tone enhancement (TE). Thus, the investigators examined the hypothesis that i-scan can improve the detection rate of reflux esophagitis and inter-observer agreement between endoscopists compared with conventional white light (WL) endoscopic examination.

The primary objective of this study is to assess the activity of subcutaneous (SC) amifostine on the incidence and severity of acute radiochemotherapy-induced esophagitis in patients with unresectable Stage IIIA or IIIB non-small cell lung cancer (NSCLC) receiving combined modality therapy.

Are we able to use the EPO staining technique using the sponge ?
