Filter by:No trial has examined the the efficacy of amoxicillin and metronidazole based quadruple therapy for Helicobacter pylori treatment. The study aims to compare the effectiveness and safety of 14-day amoxicillin-/metronidazole-based quadruple regiment and classical quadruple regiment for Helicobacter pylori eradication.
The pathophysiology of functional dyspepsia is still unclear but several peptides have been indicated in the etiological factors in FD. Ghrelin and leptin are involved in regulation of appetite and gut motility and serotonin is a typical neurotransmitter related with sensory and motor functions of gut. On the other hand, transient receptor potential vanilloid receptor 1 (TRPV1) has been proposed to be involved with functional gastrointestinal disorder, and expression of this receptor could be regulated by nerve growth factor (NGF) or glial cell-line derived neurotrophic factor (GDNF). The investigators aimed to determine whether expressions of ghrelin,leptin, serotonin,TRPV1,GDNF and NGF in blood or gastric mucosa of FD patients are different from those in healthy controls, and whether some changes of their expression correlate with certain dyspeptic symptoms. The investigators also investigated the effect of H. pylori infection by comparing their expressions before and one year after H. pylori eradication.
The purpose of this study is to understand why people with indigestion have gastrointestinal symptoms and in particular to understand whether symptoms are related to increased sensitivity to nutrients in the small intestine and to a hormone (GLP1) which is normally released from the small intestine in response to nutrients. We propose to study the contribution of GLP1 to intestinal sensitivity with a drug (exendin 9-39) that blocks the effects of GLP1.
This is a clinical study to evaluate the efficacy between Helicobacter pylori Eradication therapy and Motilitone in Functional Dyspepsia
Background: Functional dyspepsia is one of the commonest digestive disorders. The pathophysiology of functional dyspepsia (FD) is uncertain. Clinical experience and community studies show that FD is strongly associated with common mood disorders especially depression and anxiety disorders, which can be treated with serotonin selective uptake receptor (SSRI). Our previous study shows that the relief of FD symptom has an association with the change of plasma serotonin and ghrelin profile. However, the correlation between plasma serotonin level in FD patients treated with SSRI is lacking in these studies. Indication: Functional dyspepsia patients Study center(s): Prince of Wales Hospital, Hong Kong Aims : - To evaluate the effect of SSRI treatment on change of plasma serotonin level - To evaluate the relationship between dyspeptic symptom and change of plasma serotonin level Study medication: Escitalopram (Lexapro) 5mg daily for first 2 weeks, and then 10 mg daily for 8 weeks versus Placebo for 10 weeks Study design: Double-blind randomized placebo-controlled trial Number of subjects:72 - 36 patients (18 male and 18 female) and 36 age-and-sex-matched healthy controls Patient population: Functional dyspepsia patients age 18-60, with element of anxiety or depression Duration of study: 1 June 2013 - 30 November 2015 Primary variable(s): Change of serotonin and ghrelin level in blood plasma after medication treatment Secondary variable(s): Rate of adequate relief using global symptom assessment and symptom scores Number of visits: 2
Functional dyspepsia (FD) is a disorder characterized by chronic or recurrent upper abdominal pain or discomfort in the absence of a specific structural cause.1 Several mechanisms have been suggested to underlie dyspeptic symptoms. In a barostat study by Tack et al.2, impaired gastric accommodation to a meal was found in 40% of patients with FD, and this abnormality was associated with early satiety. Delayed gastric emptying (GE) was also found in almost 40% of patients with FD, and was associated with the symptoms of postprandial fullness, vomiting and early satiety.3-5 Improving gastric accommodation and prokinetic effect seem to be an attractive physiological target in patients with FD. Motilitone (Dong-A ST, Yongin, Korea) is a new herbal drug that was launched in December 2011 in Korea for treating patients with FD. It has multiple mechanisms of action such as fundus relaxation, visceral analgesia and prokinetic effects.6 The current study aims to evaluate effects of motilitone on gastric emptying and accommodation after a meal in patients with FD using three-dimensional gastric volume measurements by magnetic resonance imaging (MRI). Patients are randomly allocated to receive either motilitone 90 mg daily, motilitone 180 mg daily or placebo in a double blinded manner. After 2 weeks of treatment, patients undergo gastric MRI. The primary endpoint is gastric emptying rate. The secondary endpoints are gastric accommodation and symptom improvement.
This is a multi-Asian-centre randomised controlled trial of Rebamipide alone vs Rebamipide with Esomeprazole in the treatment of adult patients with Functional Dyspepsia. The hypothesis is that a combination therapy is superior to mono-therapy in the control of patients' symptoms and quality of life improvement.
Rome III criteria defined functional dyspepsia (FD) as the presence of symptoms from the gastroduodenal region in the absence of any organic, systemic or metabolic disease that is likely to explain the symptoms. FD can be further subdivided into two diagnostic categories: postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). Disorders of gastric electric activity and abnormal gastric emptying are probably actively involved in the FD onset. Different noninvasive procedures may be applied in order to evaluate the gastric motor functions such as 13C breath testing and cutaneous electrogastrography. Besides, different gastrointestinal peptides (i.e. CCK, peptide YY, Neurotensin, Somatostatin, Leptin, Ghrelin, Motilin, Gastrin, Pepsinogen I and II) are involved in the control of gastroduodenal motility. Aims of the present study are: 1) to evaluate the GI peptide circulating concentrations, the gastric electrical activity and gastric emptying time by applying noninvasive procedures in patients suffering from functional dyspepsia and 2) to test whether a significant difference exists between the two diagnostic categories of meal-induced dyspeptic symptoms
The purpose of this study is to examine in prospective, double-blinded randomised manner the ability of novel articaine-containing lozenge to enhance the procedure related compliance (compared to placebo) of the adult patients undergoing upper gastrointestinal endoscopy.

The primary endpoint is gastric accommodation.
