Celiac disease (CD) is characterized as an autoimmune disorder whereby gluten (a protein found in wheat, barley, rye, malt) induces an immunological response in genetically susceptible individuals. The prevalence of CD has been estimated to affect 0.5-1% of the population worldwide. Long term sequelae are numerous and include risk of lymphoma, malabsorption leading to weight loss, anemia, multiple vitamin deficiencies, osteoporosis/osteopenia, secondary autoimmunity, etc. (1)
Background: - Eosinophil-associated gastrointestinal disorders (EGID) are a group of related disorders that affect the esophagus, stomach, and bowel. There are two major types of EGID, eosinophilic esophagitis and eosinophilic gastroenteritis. They are caused by the body's immune system being activated by food allergens, which then damages the gut wall. People with EGID have large numbers of eosinophils (a type of white blood cell) in their gut. EGID can cause difficulty swallowing, abdominal pain, or nausea. - At present, there are no drugs specifically approved to treat EGID. Most adults who have EGID receive steroid therapy to manage the symptoms. However, long-term steroid use may cause other problems in the body. Researchers want to see if low-dose sirolimus can be used to treat EGID. Sirolimus is a drug used to prevent rejection of transplanted organs. It may be able to keep the body's immune cells from being activated by food allergens and decrease the eosinophils. Objectives: - To see if low dose sirolimus is safe and decreases blood or gut eosinophils in EGID. Eligibility: - Individuals between 18 to 65 years of age who have EGID. - Participants must also have an elevated blood eosinophil count and positive blood tests for IgE antibodies to foods. Design: - Participants who are on medicine for EGID or related symptoms must be on a stable dose for 1 month before screening and stay on that dose throughout the study. - Participants will be screened with a medical history and physical exam, and review their symptoms. They will provide blood and urine samples. They will also have heart and lung function tests. Some participants may have allergy skin tests. - At the first study visit, participants will have 2 days of inpatient tests. They will repeat the tests from the screening visit. They will also have a full analysis of the esophagus, stomach, and small intestine. On the second day, they will start to take sirolimus as a liquid with orange juice or water. - Participants will continue to take sirolimus at home. They will record their doses and any symptoms. They will also have a visit to provide blood samples about 2 weeks after the first study visit. - At the second study visit (about a month after the first visit), participants will repeat the tests from the screening visit. The sirolimus dose may be adjusted as needed. - Participants will take sirolimus for at least another 28 days. Depending on the dose of the drug and the blood test results, some participants may need to take it for up to 112 days. Those who take the drug for a longer period will have additional study visits with tests. - There will be another study visit when participants stop taking the drug. The last visit will be a final follow-up visit.
Background: - Food allergies are characterized by abnormal immune system responses to certain foods, such as peanuts, strawberries, and shellfish. Some individuals with these allergies have immediate allergic reactions on contact with the food in question and need immediate treatment to prevent severe complications. In contrast, eosinophil-associated gastrointestinal disorders are related disorders in which white blood cells in the intestinal tract react to certain foods, causing abdominal pain, nausea, and other digestion problems. Researchers are interested in studying these conditions to better understand how the immune system responds to food allergies. Objectives: - To examine how the immune system responds to food allergens. - To examine how certain white blood cells contribute to disease in individuals with food allergies and other inflammatory diseases. Eligibility: - Individuals between 18 and 65 years of age who have a history of (a) severe allergic reaction to peanuts (and have peanut-specific antibodies), (b) allergy or inflammatory disease, or (c) eosinophil-associated gastrointestinal disorder (with at least two documented food allergies). - Healthy volunteers between 18 and 65 years of age who have no known allergies or asthma. Design: - All participants will have a screening visit and a procedure visit. The procedure visit will take place within 30 to 60 days of the screening visit, and will take 3 to 4 hours depending on the procedure(s) done. - Participants will be screened with a physical examination and medical history, and will provide blood samples for testing. Participants with peanut or other allergies will have additional tests to determine their levels of sensitivity to certain foods. Participants with eosinophil-associated gastrointestinal disorder will provide stool samples for testing. - At the procedure visit, participants with peanut allergies and participants with other allergies will provide blood samples and have leukapherisis to collect white blood cells for examination. - At the procedure visit, healthy volunteers and participants with eosinophil-associated gastrointestinal disorder will provide blood samples and have leukapherisis to collect white blood cells for examination. In addition, some but not all of these participants will have a procedure called esophagogastroduodenoscopy (EGD), which will examine the esophagus, stomach, and small intestine. Participants who are scheduled to have EGD will be asked to fast for 6 hours before the procedure.
Therapy-associated diarrhea during radiation therapy of small pelvis (including enteritis as a result of radiation therapy and enteritis as a result of radiation- and chemotherapy) is a common problem in multimodal cancer therapy. We investigate the therapeutic effect of either loperamide or tinctura opii in therapy- associated diarrhea in patients who receive radiation therapy of the small pelvis with or without chemotherapy.
