Filter by:The purpose of this research is to further study the relationship between gastroparesis (GP) (a condition in which the stomach cannot empty itself of food in a normal fashion) and functional dyspepsia (FD) (frequent symptoms of indigestion that have no obvious cause).

Pylori in patients with dyspepsia and GERD taking PPI Secondary objectives : to compare the sensitivity and specificity of the C^13-UBT using the new test meal and standard test meal for H.Pylori in patients with dyspepsia and GERD taking PPI. to complete the results of the Helicbacter test INFAI using new test meal for H.Pylori in patients with dyspepsia and GERD taking PPI with : - Histology score for H.Pylori in antrum an corpus using the updated Sydney System - Sex, - Age, - Body Mass Index (BMI)
The purpose of this study is to evaluate the effectiveness of the low fermentable oligo-di-monosaccharides and polyols (FODMAP) diet in functional dyspepsia (FD). The investigators will compare education in the low FODMAP diet to a standard healthy diet for improving symptoms in FD.
The purpose of this study is to find out if people who have non-erosive reflux disease (NERD) have changes the investigators can see with a microscope (called confocal endomicroscopy) that is used during endoscopy (a camera scope evaluation of the inside of your stomach and swallowing tube). Traditionally the investigators have used trials of acid blocking medications (PPIs), endoscopy and measurements of acid in the swallowing tube (the esophagus) to determine if the investigators think acid is causing troublesome symptoms. The medical community believes that these symptoms are due to increased spaces between the cells that make up the swallowing tube. The investigators can directly see those spaces with a new microscope that the investigators can pass through the camera scope. Participants will be assigned to take one of two medications omeprazole and sucralfate (both approved medications for stomach symptoms) to treat their symptoms and record how well the treatment works. The investigators then will look to see if the microscope can predict which medication will work best for patients in the future. The investigators also plan to measure the acid levels in your swallowing tube and do a camera evaluation of your swallowing tube and stomach as this is standard for patients with your symptoms. The investigators will compare the results of those studies to the microscope findings.
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 principal investigator hypothesizes that participants receiving NSAID drugs with dyspeptic symptoms have increased production of gastric levels of free radicals. The primary objective of the study is to determine if Esomeprazole Magnesium increases gastric total antioxidant capacity and decreases gastric free radical production in humans. Participants (age 18 years and older) with no history of upper GI bleeding who are receiving non-steroidal anti-inflammatory drugs and then develop dyspepsia will be recruited from our primary care clinic in Washington, DC. All eligible participants will undergo biopsies of antrum and corpus. The participants will be randomized to receive either Zantac OTC or Nexium for 15 days. On day 15, all participants will undergo repeat upper endoscopy to obtain biopsies of antrum and corpus. Tissue samples will then be extracted to determine total antioxidant capacity and lipid peroxide levels (as an indirect marker of free radical production).
