Title of Study: Diarrhea-Predominant Irritable Bowel Syndrome in Persian Gulf Veterans (Controls)

Principal Investigator: Dr. Ashok Tuteja VAMC: Salt Lake City (660)


DESCRIPTION OF RESEARCH BY INVESTIGATOR


TO POTENTIAL PARTICIPANTS: Federal regulations require written informed consent before participat­ion in a research study. This is to be certain that research subjects know the nature and risks of the study, as they make a decision to participate or not to participate. You are asked to read the following information and discuss it with the investigator, so that you will be fully informed about this research study and how it may affect you. Your signature on this form means that you have been fully informed and that you freely give your consent to participate.


BACKGROUND: Many Gulf War Veterans have diarrhea, gas (bloating) and stomach pain of unknown cause. These symptoms can be because of a disease called irritable bowel syndrome diarrhea (IBS-diarrhea). The cause and treatment of IBS-diarrhea has not been studied well in Gulf War Veterans. The Department of Veterans Affairs is doing a study to find out if IBS diarrhea is caused by too many bacteria in the intestines.


In this study we will compare the presence of intestinal bacteria between Gulf War Veterans who developed IBS diarrhea with those who did not. We will also compare them with Veterans who were not deployed to the Gulf.


You are being invited to take part in a research study. Before you decide it is important for you to understand why the research is being done and what it will involve. Please take time to read the following information carefully and discuss it with friends, and relatives if you wish. Ask us if there is anything that is not clear or if you would like more information. Take time to decide whether or not you wish to take part in this research study.


IBS is a disease of the intestines. Some patients with IBS have diarrhea and others have constipation. We are studying IBS-diarrhea. These patients in general have diarrhea, stomach pains and bloating (gas). The cause of these symptoms is not known. You are being invited to take part in this study because you are a Gulf War Veteran who does not have symptoms of IBS-diarrhea or you did not go to the Gulf War but were working in the United States during the War. You will serve as a comparison group. We will compare the presence of bacteria in your intestines with that of the Gulf War Veterans who have IBS-diarrhea.


The purpose of this study is to find out if too many bacteria in the intestines is the cause of IBS- diarrhea. If you decide to participate, you will come to the study doctor’s office for 1 visit.

The following are the requirements for participation:

In order to participate in the study you:

  1. Must be a Veteran who either went to the Gulf War or worked in the United States during the Gulf War

  2. Must be men or women, age 32-75 years

  3. Must not have IBS-diarrhea

  4. Must not have other bowel/ stomach diseases such as ulcerative colitis or Crohn’s disease.

  5. Must not have significant heart, lung or kidney disease

  6. Must not have cancer (except skin cancer)

  7. Must not have effects of alcohol or drug abuse

  8. Must not have unstable psychiatric disease

  9. Must not be currently participating in another research protocol that could interfere or influence the measures of the present study.

  10. Must not be on any antibiotic for at least 7 days.

This study does not allow women who are pregnant or currently breastfeeding infants.


STUDY PROCEDURE: Participation in this study involves the following:

  • Completion of three questionnaires inquiring about your bowel habits, quality of life, combat experience during the war and psychological profile. It will take approximately 45 minutes to complete these questionnaires.

  • Blood sample when drawn for other reasons: Your blood sample will be used as a comparison group against patients with diarrhea. We will not draw blood solely for this study, but we will collect 1½ (one and one-half) tablespoons from a future blood drawn done for any other reason.

  • Stool sample: Your stool will be used as a comparison group against patients with diarrhea.

  • Breathing test to check for the presence of bacteria: This test involves blowing into a mouthpiece, which collects your breath into a plastic bag. In this test you will drink a cupful of solution containing lactulose. Lactulose is a sugar which is broken down by the bacteria into gases, called hydrogen and methane. The samples of your breath will be collected every 15 minutes. This test can last up to 3 hours. This test looks for the presence of hydrogen and methane in the exhaled breath. The more of these gases present, the greater is the number of bacteria in your intestines.

  • Optional colonoscopy and biopsy will be offered if you have other indications for colonoscopy (i.e. over the age 50 years for screening, family history of colon polyps/ cancer, rectal bleeding, abdominal pain, to rule out inflammatory bowel disease): The colon is the part of intestine which connects anus to the small intestine. During a colonoscopy, a tube is passed through your anus. The colon is about 6 feet long. A visual examination of the colon and if possible a part of the small intestine will be performed. This procedure will be performed in the Gastrointestinal Laboratory at the George E. Wahlen VA Medical Center in Salt Lake City.


During this procedure, an intravenous line will be placed in your arm. This line is a catheter which will allow medication to be delivered directly into your bloodstream. You will be sedated, during which time you will be breathing on your own and even able to interact with your doctor and nurses but will be less likely to remember doing so. You will receive two drugs: Medazolam (a sedative drug, similar to Valium) and fentanyl (a pain killing drug, similar to morphine). Sometimes phenergan is also given to avoid nausea or enhance the effect of other drugs. Two biopsies (small tissue samples) will be collected from the small bowel, two from the right part of the colon and two samples from the rectum. The biopsy samples are very small, i.e., 1- 2mm (the size of the pencil tip) in size. They will be performed through the endoscope and you will not feel any discomfort from the biopsy procedure. The purpose is to determine if there is any inflammation in intestines. If any abnormal areas are found, additional biopsies may be performed. If any incidental polyps (benign tumors) are detected, they will also be removed either with a biopsy forceps or with an electric snare. This decision will be clinical one and not related to the study, but again, you will not feel any discomfort related to this part of the procedure. The endoscope will then be removed and you will be allowed to awaken. The entire length of the procedure once you have been sedated should be between 20- 45 minutes. You will not be able to drive for the rest of the day.


If you decide to participate in the study, your visit to the doctor’s office will have the following parts:

Part #1: The study will be discussed with you, and you will be asked to sign this consent form.

A physical examination will be performed. You will be asked about your health and any current illnesses or medication you are taking. You will complete 3 questionnaires.

Part #2: You will have Breathing test for the presence of bacteria. This may last up to 3 hours.

Part #3: You may be asked to undergo a colonoscopy and biopsy.


RISKS:

Questionnaires:

Potential risks include loss of confidentiality. All subjects will be assigned identification (ID) numbers to which data will be linked. Upon completion of the study all keys to the identity of the subjects will be destroyed. You may feel uncomfortable while answering some of the questions. You may decline to answer any question.


Blood draw:

As a result of the blood draw you may feel pain, bleeding or bruising at the needle site and dizziness or fainting. Infection may occur around the needle site causing redness and pain, but this is rare. The total amount of blood that will be taken during the study is about one and a half tablespoonful.


Breathing test for presence of bacteria:

The test measures how much hydrogen and methane gas is present in the breath. A liquid solution of lactulose is given before the test. There are no significant risks involved with this test. However some subjects may experience abdominal discomfort, bloating or diarrhea.


Colonoscopy and biopsy:

Colonoscopy is generally a safe procedure but complications can occur. These can include an allergic reaction to the sedation or ointment that is spread on the endoscopy (tube) that is passed into the rectum and colon. The allergic reaction is usually treated with Benadryl (diphenhydramine). Severe allergic reaction may require epinephrine. Usually there is discomfort and feeling of fullness during this test. Bleeding might occur at the biopsy site, but is usually minor. Bleeding can stop on its own or be controlled through the colonoscope; rarely does it require follow up treatment. Rarely, a hole can be made in the side of colon or rectum that can require surgery but the likelihood is less than 1 in 500. You will also be asked to sign a separate consent form prior to this procedure.


Sedation:

Moderate sedation is used during the procedure. Allergic reactions may occur causing a rash. Rarely, excessive sedation can cause breathing difficulty. Death has been reported. There is continuous heart and breathing monitoring during colonoscopy and the chance of this happening is less than 1 in 1000.


BENEFITS: The results from the colonoscopy, if indicated, will be beneficial. Having early warning about any health problems discovered during the physical exam and colonoscopy may help increase the effectiveness of treatment. The information we get from this study may help to better treat future patients with IBS-diarrhea.


ALTERNATIVE PROCEDURES: If you do not want to be in the study, you may choose not to participate without any penalty or compromise of your care. You will continue to be treated for your illness with usual medications.


CONFIDENTIALITY: All information gathered during this study will be treated confidentially. Individuals will be identified only by initials and numbers. Any information about you which leaves the hospital will have your name and address removed so that you cannot be recognized from it. Only those who work with this study will be allowed access to your information. Your identity will not be disclosed in any publication.


The information gathered from this study will be stored in locked secure cabinets in the Division of Gastroenterology, George E. Wahlen V.A. Medical Center and the University of Utah Hospital. The computerized data is saved on password-protected computers, also in secured Gastroenterology research offices. The principal investigator, co-investigator, and study coordinator will have access to this data. Your study data will be kept as confidential as possible under local, state and federal laws. By signing this informed consent form, you authorize such access.
