Clinical Utility of Handheld Hydrogen Breathalyzer in Identification of Food Sensitivities (AIRE Study)
Small intestinal bacterial overgrowth (SIBO) is defined as a condition in which an abnormally high amount of coliform bacteria is present in the small bowel and results in premature anaerobic fermentation of carbohydrates before reaching the colon. Commonly recognized causes include gastric achlorhydria, post-surgical bowel stasis, gastrocolic/coloenteric fistulas, and motility disorders leading to bowel stasis.. The current "gold standard" for the diagnosis of SIBO, is a breath test that measures the concentration of hydrogen in response to lactulose, a carbohydrate that is only metabolized by bacteria. However, its accuracy is only about...

Combination Chemotherapy in Treating Patients With Non-Metastatic Extracranial Ewing Sarcoma
This randomized phase III trial studies combination chemotherapy to see how well it works compared to combination chemotherapy with topotecan hydrochloride in treating patients with extracranial Ewing sarcoma that has not spread from the primary site to other places in the body. Drugs used in chemotherapy, such as vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, ifosfamide, etoposide, and topotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may...

Continuation Study With Budesonide Oral Suspension (BOS) for Adolescent and Adult Subjects With Eosinophilic Esophagitis (EoE)
This is a continuation study of Budesonide Oral Suspension (BOS) in adults and adolescents with Eosinophilic Esophagitis (EoE) who have completed participation in the SHP621-302 extension study. The purpose of this study is to see if BOS is safe and well tolerated over the long-term in adolescents and adults with EoE.

Cytosponge and Dietary Therapy in EoE
This study is being done to see if the investigators can use only the cytosponge ( A 10 minute, in office procedure that does not require sedation) to replace the 6-10 endoscopies routinely perform during dietary restriction and food reintroduction in EoE?

Cytosponge Protocol IRB 11-006429
Whether the cytosponge will be a useful non-invasive tool in evaluating patients with eosinophilic esophagitis?

Data and Sample Collection Study to Elucidate the Mechanisms of Eosinophilic Disorders
The purpose of this study is to elucidate the mechanisms underlying eosinophil growth, survival, migration, and function and to investigate and further characterize the pathophysiology of, clinical manifestations of, and spectrum of disease severity of eosinophilic inflammation in humans.

Defining ENDOtypes in Perioperative Hypersensitivity by Extensive Cellular and Molecular PHENotyping (ENDOPHEN)
Perioperative Acute Hypersensitivity (PAH) is a systemic reaction that occurs rapidly following injection of a drug during anesthesia. The main mechanism evoked is an immune response of immediate systemic hypersensitivity or anaphylaxis. Anaphylactic reactions are classically described as IgE-dependent and triggered by the injection of allergen which by bridging specific IgE present on the surface of mast cells, induces a massive release of histamine responsible for the observed symptoms. The diagnosis of this mechanism (IgE endotype) requires the determination of associated circulating mediators (histamine and mast cell tryptase) as well...

DEpth of EPinephrine Delivery With Auto-injectors Devices
Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. Although there are several causes of fatal anaphylaxis, food allergy is one of the most common. Epinephrine is recommended as the initial treatment of choice for anaphylaxis. A delay in epinephrine administration may contribute to an increased risk of death. Therefore, the World Allergy Organization recommends that, for the treatment of anaphylaxis, epinephrine solution be administered intramuscularly in the mid-anterolateral thigh. In France 3 auto-injector pens are available: Anapen®, Epipen® and Jext®. For weight> 30 kg, the devices have a needle size...

Detection of Metabolite Biomarkers for the Early Diagnosis and Prognosis of Cow's Milk Allergy in Children
In this study, fecal and urine samples will be collected from children diagnosed with : - IgE mediated cow's milk allergy, - suspected of a cow's milk allergy, but with negative diagnosis - IgE mediated food allergy other than cow's milk - healthy brothers and sisters of the first three groups A subset of patients with IgE-mediated cow's milk allergy will be asked to provide a urine and fecal sample yearly for prognostic purposes. The samples will be analyzed using a technique called metabolomics to identify biomarker candidates with diagnostic and/or prognostic potential. Additionally, microbiome analysis ...
