Filter by:The specific aim of the study is to investigate the relationship between the development of dyspepsia and GI dyspeptic symptoms in relation to circulating levels of peculiar GI peptides (such gastrin, pepsinogen and GLP-2) in patients with non-gastrointestinal neoplasm well controlled for emesis.
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.
The purpose of this study is to compare Cinitapride tablets with domperidone tablets (motilium), and to evaluate the efficacy and safety of Cinitapride tablets in the treatment of mild to moderate functional dyspepsia.
Background: Functional dyspepsia is one of the commonest 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 results on effectiveness of PPI are conflicting and it has been suggested that PPI is only effective for acid-related symptoms. The investigators plan to use a wireless pH monitoring system positioned at the junction of esophagus and stomach to evaluate the chronological relationship between acid exposure at this region and symptoms of dyspepsia as well as its impact on the efficacy of acid suppressive therapy in treatment of functional dyspepsia. Indication: Functional dyspepsia patients Study center(s): Prince of Wales Hospital, Hong Kong Aims: 1. To evaluate the chronological relationship between acid exposure at squamo-columnar junction (SCJ) and dyspeptic symptom in different subtypes of functional dyspepsia 2. To evaluate the relationship between acid exposure at squamo-columnar junction and dyspeptic symptom response to PPI 3. To compare the efficacy of PPI and placebo in treating functional dyspepsia patients Study medication: Esomeprazole 20mg vs Placebo o.d. Study design: Double-blind randomized placebo-controlled trial Number of subjects: 130 Patient population: Functional dyspepsia patients without concomitant gastroesophageal reflux disease (GERD) Duration of study: 1 June 2010 - 30 May 2012 Primary variable(s): Proportion of patients who report positive response to adequate relief of dyspeptic symptoms at week 8 Secondary variable(s): Dyspeptic symptom scores, symptom association probability of dyspeptic symptoms in relation to esophageal pH of less than 4 as measured at 1 cm above SCJ. Number of visits: 2 Hypothesis: Increased acid exposure at SCJ contributes to dyspeptic symptom and predicts treatment response to PPI in FD patients without concomitant GERD
The purpose of this study is to evaluate the immediate synergistic effect on the relief of severe acid-related dyspeptic pain by adding intravenous pantoprazole to the combination of oral antacid and antispasmodic agent (the conventional treatment).

Primary Objective: • To confirm the efficacy of the probiotic product Healthy Trinity (retail label)/Trenev Trio (professional label) in the improvement of symptoms in adult patients with diarrhea-predominant irritable bowel syndrome (IBS-D) and functional dyspepsia Secondary Objective: • To confirm the safety of the probiotic product Healthy Trinity (retail label)/Trenev Trio (professional label) in adult patients with IBS-D and functional dyspepsia
The purpose of this study is to compare stomach emptying using 13C-Spirulina platensis breath test and scintigraphy in healthy subjects and subjects with dyspepsia. Subjects will eat a standard meal of 2 scrambled eggs, a slice of wheat toast and 8 ounces of skim milk. The eggs will be double labeled with Technetium-99m (99mTc) sulfur colloid and 13C-Spirulina platensis. Scintigraphy is a diagnostic technique in which a two-dimensional picture of internal body tissue is produced through the detection of radiation emitted by a radioactive substance administered into the body. The location of a standard meal in the digestive system will be measured by images of the 99mTc sulfur colloid taken at periodic intervals before and after the standard meal. The 99mTc Sulfur Colloid is approved by the FDA for use in medical diagnostic procedures. Spirulina platensis is blue - green algae, which is very similar to the naturally occurring spirulina sold in health food stores as a dietary supplement. The spirulina platensis has been labeled with the 13C stable isotope. 13C stable isotope labeling is inherently safe as 1.1% of all carbon in our bodies and in the food we eat is 13C. The presence of the 13C will be measured by breath samples at periodic intervals before and after a standard meal. The FDA considers 13C-Spirulina platensis to be investigational for the purposes of this study.
