Filter by:This is a longitudinal observational study on patients with gastrointestinal and related disease. The study will be conducted for at least 10 years, following each participant over time, as they either go through relapses and remissions, or progression of their disease.
THe purpose of this study is to evaludate the Efficacy and Safety of DWC20155/DWC20156 Combination Therapy in Patients with Gastritis
Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems, including stomach cancer. Researchers want to look at samples of the bacteria. These H. pylori strains will be taken from chronically infected people. They want to identify the genetic and epigenetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get stomach cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer. Objectives: To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer. Eligibility: People ages 30-70 years who need an upper endoscopy or who were recently diagnosed with stomach cancer Design: Participants will be screened by the doctor who does their procedure and a study nurse. Participants who have endoscopy will have ~6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam. Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
Gastric cancer as one of the most common gastrointestinal cancers, radical resection of primary lesions combined with dissection of regional lymph-nodes is acknowledged by surgeons all over the world. When compared with the advanced upper third gastric cancer, proximal gastrectomy has been acknowledged as the standard therapeutic strategy for the early gastric cancer located in the upper third of the stomach. However, due to abandon the anti-reflux barrier of the digestive system caused by the dissection of the cardia and the lower esophageal sphincter, the belching、hiccup、Acid reflux、heartburn、chest pain symptoms and as well as the reflux esophagitis caused by the traditional esophagostomy permanently influence the postoperative quality of life for those patients. Nowadays, relationship between the digestive track reconstruction for proximal gastrectomy and the postoperative quality of life is still with controversies. Previous study reported the gastric tube anastomosis can minimize the reflux related symptoms when compared with traditional esophagogastrostomy. There still exited some patients need long-term anti-acid drug to control the reflux symptoms although underwent the gastric tube anastomosis. The double-track anastomosis for proximal gastrectomy may successfully control the reflux symptoms and there existed study found it is as safe as the esophagostomy. But there has no randomized control study to compare the postoperative quality of life between the gastric tube anastomosis and double-track anastomosis for proximal gastrectomy. By the reasons above, a randomized controlled trial is conducted with the intention to compare the intraoperative and postoperative mortality and morbidity and the postoperative quality of life between the esophagogastrostomy and the double-track anastomosis in the proximal gastrectomy for gastric cancer patients.
Background: - Eosinophil-associated gastrointestinal disorders (EGID) are a group of related disorders that affect the esophagus, stomach, and bowel. There are two major types of EGID, eosinophilic esophagitis and eosinophilic gastroenteritis. They are caused by the body's immune system being activated by food allergens, which then damages the gut wall. People with EGID have large numbers of eosinophils (a type of white blood cell) in their gut. EGID can cause difficulty swallowing, abdominal pain, or nausea. - At present, there are no drugs specifically approved to treat EGID. Most adults who have EGID receive steroid therapy to manage the symptoms. However, long-term steroid use may cause other problems in the body. Researchers want to see if low-dose sirolimus can be used to treat EGID. Sirolimus is a drug used to prevent rejection of transplanted organs. It may be able to keep the body's immune cells from being activated by food allergens and decrease the eosinophils. Objectives: - To see if low dose sirolimus is safe and decreases blood or gut eosinophils in EGID. Eligibility: - Individuals between 18 to 65 years of age who have EGID. - Participants must also have an elevated blood eosinophil count and positive blood tests for IgE antibodies to foods. Design: - Participants who are on medicine for EGID or related symptoms must be on a stable dose for 1 month before screening and stay on that dose throughout the study. - Participants will be screened with a medical history and physical exam, and review their symptoms. They will provide blood and urine samples. They will also have heart and lung function tests. Some participants may have allergy skin tests. - At the first study visit, participants will have 2 days of inpatient tests. They will repeat the tests from the screening visit. They will also have a full analysis of the esophagus, stomach, and small intestine. On the second day, they will start to take sirolimus as a liquid with orange juice or water. - Participants will continue to take sirolimus at home. They will record their doses and any symptoms. They will also have a visit to provide blood samples about 2 weeks after the first study visit. - At the second study visit (about a month after the first visit), participants will repeat the tests from the screening visit. The sirolimus dose may be adjusted as needed. - Participants will take sirolimus for at least another 28 days. Depending on the dose of the drug and the blood test results, some participants may need to take it for up to 112 days. Those who take the drug for a longer period will have additional study visits with tests. - There will be another study visit when participants stop taking the drug. The last visit will be a final follow-up visit.
The aim of the study is to find out if the experimental medicine, YF476, can make gastric carcinoids, a rare type of stomach tumour, shrink and disappear. Gastric carcinoids occur mainly in patients with chronic atrophic gastritis (CAG), a condition in which the acid-producing cells in the lining of the stomach can't make acid. Acid production is controlled by gastrin, a hormone (chemical messenger) that's released into the bloodstream. If the stomach can't make acid, blood levels of gastrin rise. High blood levels of gastrin in patients with CAG can cause other cells (ECL cells) in the lining of the stomach to grow and, over the years, to give rise to gastric carcinoids. Gastric carcinoids are usually benign, but they can become malignant. Therefore, patients with CAG and gastric carcinoids have the inside of their stomach checked regularly, by gastroscopy, to see if the gastric carcinoids need removing surgically. A gastroscope is a thin (1 cm), flexible tube at end of which is a mini video camera, which enables the user to inspect the lining of the stomach and a 'snare' to take samples of tissue (biopsies). YF476 (netazepide) is a gastrin receptor antagonist (blocks the effects of gastrin), so it's a potential new medical treatment for gastric carcinoids in patients with CAG. Up to 10 of these patients will take YF476 daily for up to 12 weeks. They'll make up to seven outpatient visits for tests, including checks on the safety of YF476 and up to four gastroscopies. At each gastroscopy, the gastric carcinoids will be measured and biopsies taken for laboratory tests. Patients will take up to 24 weeks to finish the study.
Proton pump inhibitors (PPI) have been shown to cause acid reflux related symptoms at withdrawal in healthy volunteers, a phenomenon known as Rebound Acid Hyper Secretion. Whether this also applies for patients with dyspeptic symptoms but without true reflux disease (functional dyspepsia) treated with PPI is unknown. If this is the case, it could lead to an unfortunate long term use of PPI, since the acid rebound renders withdrawal too difficult. This is a single centre, randomized, double-blinded, placebo-controlled cross over study. Study period is 12 weeks per study subject. Study subjects are referred to the study from General Practitioner (GP) and the gastroenterology department or endoscopy clinic of the investigational centre. The study population consists of patients who seek their GP because of dyspepsia without alert signs, and whom the GP may consider starting on PPI. Out patients referred to the gastroenterology department or endoscopy clinic of the investigational centre because of dyspepsia without specific exclusion criteria are also invited to participate. Baseline interview, upper endoscopy and pH monitoring are performed one week before inclusion to exclude patients with GERD. Helicobacter Pylori (Hp.) status is assessed by Helicobacter Urease Test (HUT). Hp. positive subjects without ulcus are not excluded. Patients with a positive pH monitoring will not be included in the analysis regarding the primary endpoint (Development of GERD) but will be included in the analysis regarding one of the secondary endpoints (Effect of PPI on Functional Dyspepsia). Study subjects are randomized to either pantoprazol followed by cross over to placebo or to placebo. Escape medication in the form of Gaviscon can be used on demand. Internet based questionnaires are answered weekly. Questionnaires consist of the Gastrointestinal Symptom rating Scale (GSRS) in combination with items assessing postprandial fullness and items assessing the Montreal Criteria for Gastro Esophageal Reflux Disease (GERD). Compliance to protocol is assessed at hospital visits every fourth week. At the end of study endoscopy and pH monitoring are repeated.
Primary Objective: • To confirm the efficacy of the probiotic product Healthy Trinity (retail label)/Trenev Trio (professional label) in the improvement of symptoms in adult patients with diarrhea-predominant irritable bowel syndrome (IBS-D) and functional dyspepsia Secondary Objective: • To confirm the safety of the probiotic product Healthy Trinity (retail label)/Trenev Trio (professional label) in adult patients with IBS-D and functional dyspepsia
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.
Pharmacotherapy for functional dyspepsia remains unsatisfactory. Previous randomized trials reported conflicting results on clinical effectiveness of proton pump inhibitor in patients with functional dyspepsia. This study aims to examine whether lansoprazole 15mg is more effective than placebo for functional dyspepsia in Taiwanese patients, and to investigate the association between subgroups of patients and therapeutic response.
