Active clinical trials for "Esophagitis"

This study is being done to for two reasons: To learn about the effects (good and bad) esomeprazole (an FDA approved drug for reflux esophagitis) has on your esophagus when taken correctly. To learn about the quality of life changes (good and bad) you may experience with this medication.

To investigate the efficacy and safety of PARIET twice daily (b.i.d.) in patients with Proton Pump Inhibitor-resistant reflux esophagitis

Even the patients complain GERD symptoms such as heartburn and acid regurgitation the final diagnosis could be reflux esophagitis (RE), non-erosive reflux disease (NERD) and even functional heartburn (FH). In addition, the GERD symptoms are consisted of esophageal symptoms and extraesophageal symptoms. Thus it is necessary to use effective tool for the measurement of GERD symptoms and response of proton pump inhibitor in short time. Several questionnaires have been made for the assessment of GERD symptoms in recent years However, their screening tools do not include the impact of symptoms on everyday life and take a long time to complete the questionnaires. The GERD impact scale (GIS) questionnaire has been developed to compensate for this. It is a simple, one-page, questionnaire to communicate to the doctor the frequency of reflux symptoms and their effect on quality of life, recognizing that it might also prompt clinicians to make appropriate treatment for patients' symptoms. However, there was no report regarding comparison of the characteristics and response to PPI in RE, NERD and FH groups using GIS questionnaire so far.

There is currently no reliable, noninvasive biomarker for eosinophilic esophagitis (EoE), a chronic allergic diseases characterized by significant infiltration of eosinophils in the esophagus. Because eosinophils release nitric oxide, levels of exhaled nitric oxide (FeNO) are used routinely for guiding treatment in subsets of patients with asthma. FeNO levels are also elevated in immunological diseases that do not involve the airways. The investigators hypothesize that patients with EoE have elevated nitric oxide concentration in their exhaled breath and that changes in FeNO levels could be used to measure disease activity. The objective of this study is to determine the feasibility of using FeNO as a noninvasive surrogate marker for EoE disease activity. The investigators propose to measure serial exhaled nitric oxide (FeNO) levels on a group of patients with confirmed EoE, before, during and after the course of topical corticosteroid therapy to determine whether the level declines from pre-treatment level in individual patients.

The purpose of this study is to confirm the safety profile / factors which impact safety and efficacy of Nexium capsules in daily clinical usage for the patients who have been prescribed Nexium for "gastric ulcer", "duodenal ulcer", "anastomotic ulcer", "reflux oesophagitis", "non-erosive reflux disease", or "Zollinger-Ellison syndrome"

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 purpose of this survey is to evaluate the safety and effectiveness of vonoprazan tablets in patients with gastric ulcer, duodenal ulcer, and reflux esophagitis in the routine clinical setting.

The incidence of gastrointestinal allergy is on the rise and can be manifest in a number of different clinical presentations. The goal of this study is to evaluate the measurement of CD23, a protein that can be identified stool, urine, and blood, as a non-invasive marker for use in the diagnosis and interval assessment of patients with known or suspected gastrointerstianl allergy. Eosinophilic esophagitis (EE) is a disorder typically found in school-age and adolescent children, and is more prevalent in male patients. Patients with EE typically present with symptoms of heartburn or difficulties swallowing. Blood and x-ray studies may be normal or display non-specific findings. The diagnosis of EE rests on a combination of clinical symptoms, and the results of endoscopic and histologic studies. There is currently no biochemical marker that can be used to monitor disease course in these patients. Cow milk protein intolerance (CMPI) is an allergic process affecting the distal gastrointestinal tract in infants. As such, it often presents as diarrhea without or without the presence of gross rectal bleeding in infants ranging in age from birth to 6 months of age. Children display symptoms of abdominal disress including emesis, cramping, colic, or feeding difficulties. The diagnosis is based on an appropriate clinical history and supporting physical exam (typically normal). Treatment involves removal of the offending dietary antigens which include cow or soy milk protein Eosinophilic crypt abscesses, or collections of eosinophils within the intestine can also be seen. CD23 is a protein that can be found on allergy-type white blood cells (eosinophils), as well as on the cells that line the gastrointestinal tract. Previous studies have reported increased levels of CD23 in infants with cow's milk allergy. CD23 is also elevated in infants and children with allergic disease. Levels of CD23 appears to fall in conjunction with therapy.

This is a research study of a new agent used for evaluation of inflammation in the GI tract. This agent is investigational and thus is being studied to determine appropriate dosing and administration in both normal controls (i.e. people without gastrointestinal complaints) and patients with eosinophilic disease (i.e. those with an immune reaction and inflammation in their bodies with a certain cell called an eosinophil). The study will test whether the radiolabeled agent will bind to the inflammation of eosinophilic esophagitis patients because an animal model of eosinophilic esophagitis which shows the striking deposition of eosinophil granule proteins is not available.

For Head and neck cancer and uncooperative patients, blind nasogastric tube (NGT) insertion may sometimes be very difficult because of the anatomical obstructions in the pharynx and uncoordinated swallowing motion. To solve the problem, flexible endoscope has been used widely to assist the NGT insertion via direct visual assistance, working channels/guide wires, or suture fixation. Unfortunately, these tools are not easily assessed in the outpatient department. Here, we try to use a simpler method for the flexible endoscope to guide the NGT insertion.
