Filter by:This study aims to evaluate, in patients with functional dyspepsia, a model example of medical care based upon the biopsychosocial model (called: the therapeutic encounter) compared with standard medical care based upon the biomedical model (called: medical consultation).
Proton pump inhibitors (PPI) have been shown to cause acid reflux related symptoms at withdrawal in healthy volunteers, a phenomenon known as Rebound Acid Hyper Secretion. Whether this also applies for patients with dyspeptic symptoms but without true reflux disease (functional dyspepsia) treated with PPI is unknown. If this is the case, it could lead to an unfortunate long term use of PPI, since the acid rebound renders withdrawal too difficult. This is a single centre, randomized, double-blinded, placebo-controlled cross over study. Study period is 12 weeks per study subject. Study subjects are referred to the study from General Practitioner (GP) and the gastroenterology department or endoscopy clinic of the investigational centre. The study population consists of patients who seek their GP because of dyspepsia without alert signs, and whom the GP may consider starting on PPI. Out patients referred to the gastroenterology department or endoscopy clinic of the investigational centre because of dyspepsia without specific exclusion criteria are also invited to participate. Baseline interview, upper endoscopy and pH monitoring are performed one week before inclusion to exclude patients with GERD. Helicobacter Pylori (Hp.) status is assessed by Helicobacter Urease Test (HUT). Hp. positive subjects without ulcus are not excluded. Patients with a positive pH monitoring will not be included in the analysis regarding the primary endpoint (Development of GERD) but will be included in the analysis regarding one of the secondary endpoints (Effect of PPI on Functional Dyspepsia). Study subjects are randomized to either pantoprazol followed by cross over to placebo or to placebo. Escape medication in the form of Gaviscon can be used on demand. Internet based questionnaires are answered weekly. Questionnaires consist of the Gastrointestinal Symptom rating Scale (GSRS) in combination with items assessing postprandial fullness and items assessing the Montreal Criteria for Gastro Esophageal Reflux Disease (GERD). Compliance to protocol is assessed at hospital visits every fourth week. At the end of study endoscopy and pH monitoring are repeated.
Chronic abdominal pain is the most common persistent pain condition in children and adolescents, affecting 10-15% of children at any given time. One of the most often diagnosed types of abdominal pain is functional dyspepsia (FD). FD is an abdominal pain or discomfort (e.g., nausea, bloating) in the upper abdomen that does not get better by going to the bathroom. For some people it appears that stress can make FD worse. In adults, stress can cause the release of a hormone called corticotropin releasing hormone (CRH). The release of CRH can cause abdominal pain by affecting how fast things move through a person's stomach and intestines. This makes the organs in the abdomen more sensitive to pain, causing tenderness of the inside lining of the stomach and intestines. Different people react differently when the body releases CRH. Some people have abdominal pain without feeling any stress or anxiety while other people who have a lot of stress or anxiety don't have any abdominal pain. Some people have neither stress, anxiety, or abdominal pain when CRH is released into the body. In order to see how the bodies of children with functional dyspepsia and those without functional dyspepsia react to CRH, we will do a CRH stimulation test. A CRH stimulation test is routinely done in endocrine patients. It is not routinely done for patients with functional dyspepsia or for patients who do not have functional dyspepsia. Part of the CRH stimulation test is giving a synthetic type of corticotropin, Acthrel® (brand name for Corticorelin), as injection. Acthrel® has been approved by the Food and Drug Administration (FDA) for use. The purpose of this research study is to see if there are differences in how the bodies of children with functional dyspepsia react to CRH versus children who don't have functional dyspepsia. Being in this study involves one clinic visit where an IV placed and a CRH stimulation test. In this test the child will be given an injection of CRH and then observed for one hour. During that hour the child will have five blood draws through the IV and will be asked questions about their anxiety and abdominal pain. This visit will take about 4 hours. The following things will happen: - Your child will be asked to come to the clinic between 8a.m. and 10a.m. fasting. This means your child will have had nothing to eat or drink for 8 hours before coming to the clinic. - If your child is a female ten years of age or older, or has started having periods, a urine pregnancy test will be done before receiving the CRH infusion. - You and your child will each be asked to complete a survey that measures your child's anxiety. - Your child will have a biofeedback session that will measure your child's stress. In a biofeedback session, sensors are placed on your child's fingers, wrists and forehead. These sensors are connected to a computer that monitors your child's heartbeat, skin temperature and electrical pulses on your child's skin. - Your child will have an IV inserted into a vein in his/her arm. Your child may have a cream put on their arm to help with the pain of the IV insertion. The IV will be used to inject the CRH and draw blood. If the IV stops working and blood samples can no longer be drawn from it, your child may have another IV started or blood samples may be drawn by needle stick. - Your child will then have 30 minutes to relax. - Your child will then have CRH infused through the IV over one minute. - Your child will have blood drawn through the IV five times; right before the CRH stimulation test begins and 15, 30, 45 and 60 minutes after the CRH infusion. The total amount of blood drawn for the study will be about 2 ½ tablespoons. - Your child will be asked about their abdominal pain, nausea, bloating, stress and anxiety at three separate times during the 60 minutes. - Your child's heart rate will be measured throughout the CRH stimulation test.

Double-blind randomized controlled trials of 8 weeks mirtazapine 15 mg daily or placebo, followed by 8 weeks of open-label mirtazapine 15 mg daily
Pathogenesis of functional dyspepsia is poorly understood. Gastrointestinal motor abnormalities, Helicobacter pylori infection, impaired gastric accommodation to a meal, hypersensitivity of the afferent nerves of the gut, psychological disturbances and central nervous system dysfunction have been proposed. Pharmacological treatments for patients with functional dyspepsia remain unsatisfactory. Only small benefits relative to placebo have been found with histamine H2 receptor antagonists, proton pump inhibitor and Helicobacter pylori eradication. Itopride is a dopamine antagonist with acetylcholinesterase inhibitory actions. This agent is currently indicated for patients with various upper GI symptoms. This study is aimed to evaluate the effect of Itopride on gastric emptying(by 13-C Octanoic acid breath Test), accommodation (by Gastric Scintigraphy SPECT and slow nutrient drinking test)and symptoms in FD patients
The purpose of this study is to assess the efficacy and safety of rabeprazole compared to placebo in Japanese subjects with Functional Dyspepsia.
This trial aims to compare the endomicroscopic image quality and sedation efficacy of propofol or midazolam with fentanyl.
The purpose of this study is to evaluate the effectiveness of gabapentin on symptom control in patients with defined functional dyspepsia refractory to conventional proton pump inhibitor therapy and to compare these effects to that of placebo.
Background: Functional gastrointestinal disorder (FGID) is the most common gastrointestinal disease in daily clinical practice. The disease is symptomatic but has no identifiable cause by standard diagnostic tests such as endoscopy. It is characterized by its frequent relapses and thus the disease causes a significant level of stress and anxiety to patients. Due to the complexity and chronicity of the disease, it is believed that appropriate counseling on the nature and management of the disease is necessary to decrease patient's anxiety level and improve quality of life. Indication: Patients who have symptoms suggestive of FGID including non-erosive gastroesophageal reflux disease (NERD), functional dyspepsia (FD) or irritable bowel syndrome (IBS). Aim: To validate the effectiveness of counseling in patients suffering from FGID. Method: Patients recruited to the study will follow the usual management of patients attending the Gastroenterology specialty clinic in Prince of Wales Hospital. Standard blood tests and endoscopy will be performed. Standard medication will be given to the patients for 8 weeks after endoscopy and the patients will come back to the specialty clinic for a final visit. The patient will be given an "on-demand follow up within 1 year" option at final visit. The patient will decide if he/she wants to come back to our specialty clinic to follow up his/her problem within one year. Follow-up after Final Visit Follow-up questionnaires will be mailed to patients 6 months, 1 and 2 years after Final visit. Randomization: All the patients will be randomized into two groups in First Visit: 1) Control group, and 2) Counseling group. Both groups of patients will follow the above protocol, except that 2 extra counseling sessions will be arranged for the Counseling group immediately after visiting the physician.
