Natural History of Hypereosinophilia and Hypereosinophilic Syndromes

EosinophiliaHypereosinophilic Syndrome

Unexplained chronic hypereosinophilia (HE) and hypereosinophilic syndromes (HES) are heterogeneous regarding the organ involvements (heart, lungs, skin, .. or none), the evolutionary profiles, the response to treatments. Underlying mechanisms are largely unknown and may associate genetic predisposing factors (germinal ? somatic?), environmental factors (alimentation, tobacco use, hormones, infections, ..) The COHESion study aims to study all clinical and biological characteristics of HE/HES patients and their evolutionary profiles, with a focus on genetic factors and the mechanisms supporting transitory or persistant chronic HE/HES (in absence of any well identified extrinsic trigger like drugs, parasitosis, ..)

Changes in Esophageal Distensibility With Proton Pump Inhibitors in Patients With Esophageal Eosinophilia:...

Eosinophilic Esophagitis

This pilot study will explore whether treatment of eosinophilic inflammation in the esophagus is associated with an improved distensibility of the esophagus. Furthermore, previous studies of the esophagus using EndoFlip only measured distensibility of the distal esophagus, specifically the distal esophagus and esophagogastric junction. Eosinophilia in EoE has been demonstrated to affect both upper, middle and lower esophagus. The aim is to measure distensibility both proximal and distal, before and after treatment.

Study of Gastric Motility in Eosinophilic Gastritis

Eosinophilic GastritisGastroparesis1 more

Purpose: The study is a cross-sectional observational study designed to determine if eosinophilic gastritis (EG) results in gastric motility impairment. Hypothesis: Gastric dysfunction occurs in the natural history of EG but is underdiagnosed due, in part, to contraindications to the use of the standard meals used in gastric emptying studies.

OMEGA: Outcome Measures in Eosinophilic Gastrointestinal Disorders Across the Ages

Eosinophilic Gastrointestinal Disorders (EGIDs)Eosinophilic Esophagitis3 more

The purpose of this observational study is to find the best measures to define how well a person with eosinophilic disorder is doing. People with EoE, EG, EGE and EC normally undergo endoscopy and/or colonoscopy where cells are collected for microscopic analysis. Treatments are then decided based on how the cells look. We are aiming to compare different tissue components such as inflammatory cell types with clinical symptoms. We want to see if scores on standard questionnaires can give us an idea how well the person is doing.

Steroid Treatment for Hypereosinophilic Syndrome

EosinophiliaHypereosinophilic Syndrome2 more

Background: - Hypereosinophilic syndrome (HES) is a disorder in which the body has too many eosinophils (a type of white blood cell). Too many eosinophils in HES can cause damage to the heart, nerves, or skin. Certain drugs can help lower eosinophil counts to prevent tissue damage. Corticosteroids, such as prednisone, are used for initial therapy in this disorder. Although most people respond to prednisone, some people develop side effects from it, or do not respond very well to treatment. Better ways of determining the dose to give could help to decide on the best therapy for HES. Objectives: To determine whether a single-dose of prednisone can be used to predict which people with hypereosinophilia respond to treatment. To study lack of response to steroid treatment in people with HES. Eligibility: Inclusion criteria: Individuals with hypereosinophilic syndrome with high eosinophil counts. Individuals who are willing to have blood drawn before and after getting steroids. Exclusion criteria: Individuals who are on more than 10mg of prednisone (or similar drug) Individuals with hypereosinophilic syndrome who are on other medications that could interfere with the study Women who are pregnant or breast-feeding Individuals who have a known gene mutation associated with chronic eosinophilic leukemia Children less than 18 years old who weigh less than 48kg or 106lb Design: Participants will have a screening visit with a physical exam and medical history. Blood and urine samples will be collected. Participants will have a single dose of the steroid prednisone by mouth in the morning. Blood samples will be collected 2, 4, 24 hours after this dose. On the day after the steroid dose, participants will provide another blood sample in the morning. Participants will start to take prednisone daily when they return home. Blood samples will be collected weekly at the participant s doctor s office. The dose of prednisone will be lowered depending on the weekly eosinophil count. We will try to get each person on the lowest dose of prednisone possible that will control the disorder. Participants who do not respond or have severe side effects will be taken off prednisone. Other treatments will be considered for people who do not respond to steroids. The goal is to evaluate the response to prednisone. Our research will try to figure out why some people do not respond to steroids. Most people will complete the study within 6 to 16 weeks, depending on their response to prednisone.
