Active clinical trials for "Dyspepsia"

Chronic dyspepsia, or a sensation of indigestion, remains an underdiagnosed and often inappropriately managed cause of morbidity in countries with limited medical resources. A recent questionnaire of Eastern Ugandan residents identified chronic dyspepsia as the most bothersome symptom in nearly 60% of respondents, resulting in significant morbidity and work days missed. One of the most common causes for chronic dyspepsia worldwide is infection with the stomach-adapted bacterium Helicobacter pylori (Hp), the most significant risk factor for the development of stomach cancer. In developing countries, particularly in sub-Saharan Africa, the prevalence of Hp has not been accurately determined, often owing to a lack of adequate diagnostic methods. More importantly, proper diagnosis and treatment of chronic dyspepsia would limit morbidity and mortality and help decrease the likelihood of progressing to stomach cancer. The purposes of this study are to identify the prevalence of chronic dyspepsia among residents of eastern Uganda using a questionnaire, to assess how common Hp infection is using fecal Hp antigen test kits, and to evaluate the efficacy of Hp eradication using standard Ugandan treatment guidelines. Participants who test positive for Hp infection by fecal Hp antigen testing will be offered Hp eradication treatment in the form of two antibiotics (clarithromycin, amoxicillin) and an acid-suppression medication (omeprazole), according to the current Ugandan guidelines. Patients with chronic dyspepsia who are negative for Hp (by fecal antigen testing) will be given a one-month trial of omeprazole alone, according to current American College of Gastroenterology guidelines, and their symptoms will be reassessed. At the end of the treatment regimens, participants will have the option to complete a follow-up questionnaire and provide stool samples for fecal antigen testing (if they were Hp-positive).

This study aims at evaluating efficacy and safety of high-dose esomeprazole and amoxicillin dual therapy(esomeprazole and amoxicillin) versus bismuth-containing quadruple Therapy(bismuth，esomeprazole，tetracycline and furazolidone) in H. pylori rescue therapy. It is hypothesized that high-dose esomeprazole and amoxicillin dual therapy is non-inferior to bismuth-containing quadruple Therapy. Patients with confirmed failure of H. pylori eradication will be randomized to one of the treatments described above. At week 6 follow-up visits, a urea breath test，rapid urease test or helicobacter pylori stool antigen test will be performed to confirm eradication.

There are two specific aims in this study. Specific Aim 1: Determine if melatonin results in a higher grade of clinical response than does placebo in children with functional dyspepsia (FD). Hypothesis: treatment of FD with melatonin will result in a higher grade of clinical response than will treatment with a placebo. Specific Aim 2: Evaluate the relationship between changes in sleep and improvement in pain in pediatric patients with functional dyspepsia receiving melatonin. Hypothesis: There will be no association between improvement in pain and improvement in sleep in children with functional dyspepsia receiving melatonin.

This study is designed to study benefit of eradicating Helicobacter Pylori in patients with functional dyspepsia as compared to symptomatic treatment only. Helicobacter pylori positive patients with Functional Dyspepsia will be divided into two study groups, one will receive Helicobacter pylori eradication therapy and other will receive symptomatic treatment. Symptom relief based on Likert scale will be compared in both groups.

Objective: To observe the effect of the treatment of transcutaneous auricular vagus nerve stimulation (taVNS) for the functional dyspepsia (FD). Methods: We accrued 94 patients at Beijing TongRen Hospital. All treatments were self-administered by the patients at home after training at the hospital. Patients completed questionnaires at baseline and after 4 weeks, 8 weeks, 12 weeks. The FD Symptoms Index, Functional Dyspepsia Quality of Life Scale (FDDQL), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and Self-Depression Rating Scale (SDS) were performed to evaluate the therapeutic effects. A difference of P < 0.05 was considered statistically significant.

Background. Abdominal distention is produced by an abnormal somatic postural tone. We developed an original biofeedback technique based on electromyography-guided control of abdominothoracic muscular activity. In a randomized, placebo-controlled trial we demonstrated the superiority of biofeedback over placebo for the treatment of abdominal distention. However, the technique is technically complex and unpractical. Aim. To prove the efficacy of a simplified biofeedback technique for the treatment of abdominal distension. Selection criteria. Visible abdominal distension after meal ingestion; patients are able to identify the offending meal. Intervention. Patients will be randomized into biofeedback in placebo groups.Three sessions of either biofeedback or placebo intervention will be performed 30 min after ingestion of the offending meal during the first 3 weeks of the intervention period. Biofeedback: patients will be taught to control abdominal and thoracic muscular activity by providing a visual display of the abdominal and thoracic perimeter; specifically, they will be instructed to reduce the abdominal perimeter (girth); patients will be instructed to perform the same exercises before and after breakfast, lunch and dinner during the 4-week intervention period. Placebo: abdominal and thoracic perimeter will be recorded but not shown to the patient and a pill of placebo containing 0.5 g glucose will be administered; patients will be instructed to take a pill of placebo before breakfast, lunch and dinner during the 4-week intervention period. Primary Outcome Measure: Effect of the probe meal on the activity of thoraco-abdominal muscles (intercostals, external oblique, internal oblique, upper rectus, lower rectus) measured by electromyography before and after the probe meal. The response to the probe meal will be measured before and after treatment. Secondary Outcome Measures: Effect of the probe meal on sensation of abdominal distension measured by 0-6 scales after the probe meal. Changes in girth produced by the probe meal measured using a non-stretch belt placed over the umbilicus before and after the probe meal. Sensation of abdominal distension measured by 0-6 scales after each meal (breakfast, lunch, dinner) over a 7-day clinical evaluation period before and during the 4th week of the intervention.

The purpose of this study is to evaluate the immediate synergistic effect on the relief of severe acid-related dyspeptic pain by adding intravenous pantoprazole to the combination of oral antacid and antispasmodic agent (the conventional treatment).

The purpose of this study is to compare Cinitapride tablets with domperidone tablets (motilium), and to evaluate the efficacy and safety of Cinitapride tablets in the treatment of mild to moderate functional dyspepsia.

The aim is to evaluate if the resolution of upper abdominal symptoms (pain or burning) during an acid suppressive test trial of esomprazole given daily for 7 days predicts symptoms resolution at the end of a subsequent treatment period of 7 weeks.
