Cyclic Vomiting Syndrome (CVS)

Two Online Studies on Cyclic Vomiting Syndrome (CVS)

Purpose of study 1: A research study is being conducted in order to learn what the experiences are regarding two nutritional supplements, co-enzyme Q10 (also known as "Co-Q") and L-carnitine (Carnitor), and one medication, amitriptyline (Elavil), for the treatment of CVS. 

Sponsor: Eligible individuals of any age previously diagnosed with CVS

Participation: Eligible children aged 7 to 12 who have experienced at least 3 episodes of unexplained abdominal pain over a 3 month period.

Gastroesophageal Reflux Disease (GERD)

GERD and Anti-Reflux Therapy Between Individuals with Spinal Cord Injury (SCI) and Able-Bodied Individuals

Purpose of study: Respiratory dysfunction, esophageal dysmotility, and a gastroesophageal reflux disease (GERD) have been demonstrated to be highly prevalent in persons with spinal cord injury (SCI). GERD has been linked to respiratory symptoms and conditions such as asthma, chronic cough, and an increased rate of respiratory infections in the general population. In persons with asthma, respiratory symptoms and dependency on asthma medications have been reduced by treatment with anti-reflux medication. Possible mechanisms have been proposed for this link, including the microaspiration of reflux materials, which may result in airway acidification and aspiration pneumonia, or the stimulation of the vagus nerve through acid-sensitive receptors in the esophagus with associated esophageal inflammation and reflex bronchoconstriction. Investigators propose to study the effects of anti-reflux therapy (proton pump inhibition) in persons with SCI on objective and subjective symptoms of respiratory function to determine the underlying mechanisms of airway inflammation due to GERD.

Sponsor: James J. Peters Veterans Affairs Medical Center

Participation: Adult male and female individuals between the ages of 18 and 75. Specifically looking for

1. Able-bodied patients who are not diagnosed with GERD during screening who will act as controls.

2. SCI patients who are not diagnosed with GERD during screening and will act as controls.

3. For individuals with SCI who are identified with GERD, they will undergo an 8-week treatment of the PPI Omeprazole to reduce GERD.

4. Able-bodied individuals who are identified with GERD will act as controls. Note: They will not receive treatment for GERD in this study. We will notify their primary care physician during the study so that they may receive treatment.

Pediatric Gastrointestinal Disorders

Participants Needed for Study on the Defecation Habits of Young Children

Purpose of study: The purpose of this research study is to learn more about the relationship between children's bowel habits and the way they react to sensory input. Some children are very sensitive to the way things feel, smell, and sound, and this might interfere with their willingness to use the toilet for a bowel movement. Eligible participants will be asked to complete 4 questionnaires with questions related to these reactions to sensation and bowel habits of children.

Sponsor: University of Newcastle

Participation: Parents of children between ages 3 and 6 years. The study will include children with or without functional defecation issues who may or may not also have a diagnosis of ADHD or autism. Excluded from the study are children with organic defecation issues and/or a diagnosis other than ADHA or autism.

Chronic Intestinal Pseudo-Obstruction

Diagnostic Gene Studies for Chronic Intestinal Pseudo-Obstruction

A mutation in a gene transmitted through a dominant mode of inheritance (an affected person having a 50% risk of passing the disorder to each of his or her children) can cause chronic intestinal pseudo-obstruction (CIPO), with or without frequent bladder involvement. The disorder can also occur due to a new mutation. Thus far, the most important gene discovered with mutations is the ACTG2 gene.

A second gene is being sought by the Center for Human Genetics. Families who wish to participate in this research effort can email Aubrey Milunsky, MD at This email address is being protected from spambots. You need JavaScript enabled to view it. for details.

Online Survey on Symptoms in IBS

Purpose of study:  One of the most important questions for individual patients with irritable bowel syndrome (IBS) is how long the symptoms will continue. A number of factors are thought to be important in determining recovery from IBS but so far studies have not been big enough to be certain of the results. The aim of this world-wide survey will be to gather together the experience of a large number of patients with irritable bowel syndrome, both those in whom it has begun with an infection and those in whom it has not. By comparing these we will be able to understand more about both conditions.

About the study: This is a web-based survey designed to help learn more about irritable bowel syndrome in order that physicians might better plan treatments and management. Of particular interest is how symptoms develop over time. The study is multilingual and is currently available in nine languages.

Sponsor: European Gastroenterology Federation

Gulf War Multisymptom Illness

The War Related Illness and Injury Study Center (WRIISC) is Recruiting for Multiple Studies  

Purpose of research: The onset of certain gastrointestinal (GI) disorders, including irritable bowel syndrome (IBS), functional dyspepsia, and chronic abdominal pain syndrome, can be triggered by severe stress and infections of the digestive tract. Deployed military personnel face an elevated chance of experiencing these risk factors and developing a disorder as a result of their service. A prominent condition affecting Veterans of the Gulf War theater of operations is a cluster of medically unexplained chronic symptoms. Collectively, these are referred to as "multisymptom illness."

The War Related Illness and Injury Study Center (WRIISC) regularly conducts research into these illnesses to understand the underlying mechanisms and develop treatments to help manage symptoms. 

Sponsor: US Department of Veterans Affairs (VA) 

Participation: Veterans of active service in the Gulf War theater of operations.
