Active clinical trials for "Dyspepsia"

This study is being done to evaluate the long-term safety of tegaserod in women with symptoms of dyspepsia who have completed the core study. Tegaserod will be evaluated at 6 mg twice daily.

Functional dyspepsia is one of the most common digestive disorders. The pathophysiology of functional dyspepsia is uncertain. Proton pump inhibitor (PPI) has been recommended as the first line treatment for functional dyspepsia. However, the mechanism of symptom relief is unclear. Most of the previous studies were performed on healthy volunteers who received only a very short course of PPI. The correlation between symptom and gastric emptying is lacking in these studies. Demographic data and anthropometric measurements will be obtained for baseline assessment. Patients are required to complete FGI Screening Questionnaire, Functional dyspepsia symptom questionnaire, gastroesophageal reflux disease (GERD) symptom questionnaire and irritable bowel syndrome (IBS) symptom questionnaire to have a thorough assessment of their GI symptoms. (1) Satiety test and ghrelin profile, and (2)gastric emptying test will be arranged as two individual visits. After baseline investigations, patients will be randomly assigned to either Nexium 20 mg daily or identical looking placebo for 8 weeks. The patients will report their individual dyspeptic symptoms on weekly basis using a self-administered symptom questionnaire. Satiety test and ghrelin profile, gastric emptying study will be repeated at the end of 8-week treatment. Hypothesis: Long-term PPI relieves dyspeptic symptom through acceleration of gastric emptying rate.

There is some controversy in the medical literature regarding the effectiveness of topical lidocaine in children as an adjuvant drug to upper gastrointestinal endoscopy. In children, deep sedation and general anesthesia are often used to sedate children submitting to this procedure. Propofol is an anesthetic drug increasingly popular in this situation, but this drug can only be used with an anesthesiologist in Brazil. Its main side effects include hypotension, respiratory depression and local pain. Lidocaine is frequently used as premedication, and the rationale is that lowering patient discomfort could lower the required dose to achieve the endoscopy and reduce potential side effects. Nevertheless, some patients perceive this medication as uncomfortable. This study aims to compare sedative drug doses between patients who were given either placebo or topical lidocaine.

Helicobacter pylori eradication and its impact on symptoms in patients with non-ulcer dyspepsia remain controversial . Many studies have examined the effect of H. pylori eradication on dyspeptic symptoms, but the results have been conflicting and inconclusive, with as many studies yielding positive as negative results. Some studies have shown a significant (although weak) symptomatic improvement after H. pylori eradication, and while other yielding negative results. A recent Cochrane review has comprehensively demonstrated that H.pylori eradication therapy has a small but statistically significant effect in H.pylori positive non-ulcer dyspepsia. An economic model suggests this modest benefit may still be cost effective . However it is difficult to reconcile these results in areas with very high prevalence of H. pylori infection such as Pakistan since no such studies have been conducted in developing countries. The investigators hypothesize that eradication of Helicobacter pylori (H. pylori) leads to a sustained improvement in symptoms of patients diagnosed with H. pylori associated functional (non-ulcer) dyspepsia.

To evaluate the efficacy and safety of Z-338 in subjects with Functional Dyspepsia

Itopride is a new compound that is already marketed in Japan and in some countries of Eastern Europe under the name of Ganaton. It is used to treat symptoms of functional dyspepsia. Patients suffering from this condition have difficulties digesting food. They feel full after eating a few bites; they feel bloated and their stomachs hurt. The goal of this study is to see if itopride helps to relieve the symptoms of functional dyspepsia.

Functional dyspepsia is a common gastrointestinal disorder. Symptoms can include stomach pain or discomfort, bloating, fullness after eating meals, and nausea. These symptoms often interfere with school and work, and weight loss may occur due to dietary restrictions. The hypothesis of this study was that antidepressant therapy is more effective than placebo in relief of the symptoms of functional dyspepsia, adjusting for psychological and psychiatric co-morbidity. The study also examined if antidepressant therapy reduces disability and improves quality of life in functional dyspepsia.

Background: The aim of the study was to assess the role of melatonin in chronic dyspepsia in this group of women, with consideration of Helicobacter infection. Methods: The study comprised 152 subjects Including 30 healthy women (group I), 60 women with asymptomatic H.pylori infection (group II), and 64 women H. pylori infected with chronic dyspepsia(group III). Endoscopic examination, histological assessment of gastric end duodenal mucosa, urease breath test(UBT-13C), and serum levels of 17-β-estradiol, follicle stimulating hormone, melatonin and urinary concentration of 6-sulfatoxymelatonin were determined by immunoenzymatic method. In group III - 14-day antibacterial treatment was introduced with pantoprazole, amoxicillin and levofloxacin. Afterward, in 32 women was administered placebo(group IIIa), and in 32 women (group IIIb) melatonin at a dose 1 m/morning and 3 mg/at bedtime, for six months.
