Filter by:Our hypothesis is that patients with GERD and/or Eosinophilic Esophagitis (EE) have lower esophageal impedance measurements when compared to patients who do not have GERD or EE.
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 the trial is to develop a treatment protocol to be used in trials studying internet-delivered CBT for children with functional gastrointestinal disorders (FGID). The study size is not based on power calculations but the estimated sample necessary to develop a treatment protocol. This study will include 20-30 children with FGID and their parents who will be treated individually (face-to-face). The treatment consists of 10 weekly sessions of exposure-based CBT. The study uses a pre- post-design with no control group.
The purpose of this study is to assess the efficacy and safety of Rikkunshito compared to placebo in Japanese subjects with Functional Dyspepsia (FD).
Dyspeptic symptoms, such as pain after eating, bloating and nausea all have major impact on quality of life and health care costs. When no structural cause is identified, patients are diagnosed with functional dyspepsia. This trial aims to identify objective abnormalities of stomach function that explain patient's symptoms and establish diagnosis. Another group are diabetic patients who can often develop similar symptoms, labelled as diabetic gastroparesis. In some cases this is associated with delayed gastric emptying but not all. 24 patients with functional dyspepsia will be studied and 24 healthy controls (to establish normal ranges) and 24 diabetic patients with symptoms of functional dyspepsia. The utility of 3 different non-invasive investigations will be assessed. At screening the nutrient drink test (NDT) asks the patient to drink 40ml of milkshake (0.75kcal/ml) every minute and score symptoms every 5 minutes. The patient continues until they reach the maximum tolerated volume. Participants will then be randomized to undergo non-invasive imaging on two separate test days by magnetic resonance imaging (MRI) and gastric scintigraphy MRI will be completed with the patient ingesting 400ml of milkshake (identical to NDT) and 12 agar beads (no additional calories) of known breaking strength. The emptying of the stomach will be visualised with the MRI alongside symptom recording. Gamma scintigraphy will ingest the same meal as for the MRI scan but radioactive labelling will allow the rate of liquid and solid meal emptying to be visualised alongside symptom recording. Additionally, blood sugars will be recorded before nutrient drink test and at 15 and 30 minutes following ingestion of 400ml of milkshake and 12 agar beads. Data will be analyzed to assess the association of objective abnormalities of gastric function and patient symptoms. Additionally the results of non-invasive imaging by MRI and GS will be compared to assess the optimal measurement of gastric function and emptying in this clinical scenario.
This is a phase IV , comparative study to evaluate the efficacy and safety of Motiltone® in treatment of the patients with functional dyspepsia. The study is conducted with following methods: multi-centers, double blind, randomization, parallel. The subjects will receive Motilitone® or/and Pantoline®.
Hypothesis: Acupuncture is efficacious and safe for patients with functional dyspepsia Design: - A single blind randomized controlled trial - 200 participants will be included - Two arms: acupuncture and sham acupuncture group
The increase of antibiotic resistance to H. pylori causes failure of treatment. Furazolidone, amoxicillin and tetracycline are good candidates for rescue therapy since resistance to these three antimicrobials was rare. It is necessary to assess the efficacy and safety of these four bismuth-containing quadruple regimens with above antibiotics as empirical rescue therapies for H. pylori eradication.
To examine and compare the efficacy of 2 week Levofloxacin-containing therapies with and without Bismuth for H.pylori treatment.
The purpose of this study is to observe the efficacy of ten day triple therapy-based, bismuth-containing quadruple therapy for H.pylori treatment.
