Filter by: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 examine the safety and efficacy of Z-338 (YM443) after long-term administration in patients with functional dyspepsia, and also to examine the pattern of long-term administration.
The purpose of this study is to verify the superior efficacy of Z-338 to placebo in subjects with Functional Dyspepsia, focusing on the assessment of subjective symptoms.
Visceral hypersensitivity as evidence of central sensory sensitization is evident in many patients with functional disorders such as functional dyspepsia (FD) and irritable bowel syndrome (IBS). We recently demonstrated both somatic hypersensitivity and abnormal endogenous pain modulation in IBS, both of which indicate central sensitization as a crucial mechanism in IBS. Endogenous pain mechanisms regulate, fine-tune and integrate sensory and homeostatic, including neuroendocrine, immune, motor and autonomic nervous system processes. Hitherto, no studies have investigated the role endogenous pain modulation in FD. Abnormal modulation could explain several of the symptom complexes associated with FD and provide a rationale for exploration of new treatments. The current study was designed to 1. investigate the gastric sensitivity in FD patients and healthy controls during gastric capsaicin stimulation 2. assess the endogenous pain inhibitory modulation system in FD patients and healthy controls during heterotopic stimulation
The purpose of this study is to compare postprandial distress syndrome and epigastric pain syndrome in demographics psychological features, infection of Helicobacter pylori, gastric emptying and therapeutic response to lansoprazole.
Functional dyspepsia is a common symptom complex with significant impact on quality of life. There is no standard treatment for functional dyspepsia but therapeutic efficacy of proton pump inhibitor (PPI) and prokinetic agent have been proved in subsets of patients. This study has two aims: - first is to compare the therapeutic efficacy of lansoprazole (a PPI) and mosapride (a prokinetic agent) for functional dyspepsia - second is to investigate whether different subgroups of functional dyspepsia (e.g., epigastric pain syndrome and postprandial distress syndrome) respond differently to PPI and prokinetic agent.
The purpose of the study is to testify the efficacy of treating functional dyspepsia with acupuncture, and provide evidence for the hypothesis that "Acupuncture effect is based on meridians, and gathering of meridian Qi is the key point."
A double-blind clinical trial investigating if a sub-group of functional dyspeptic patients without any use of NSAID or gastric erosions could have a better evolution of their dyspeptic symptoms after Helicobacter eradication than the placebo control group
The main purpose of this study is to evaluate whether intestinal permeability and/or serum zonulin concentration is increased in children/adolescents with functional dyspepsia (FD). The study will also explore the relationships between intestinal permeability, mucosal inflammation and anxiety in FD patients.
To Evaluate the efficacy of Z-338 in subjects with Functional Dyspepsia, focusing on the assessment of subjective symptoms in order to further determine the optimal dosage and efficacy parameters for PhaseIII clinical trials.
