Describes the nature of a clinical study. Types include:
Allergic and immunologic disorders are very common but some are very poorly understood. Numerous studies of the epidemiology, characteristics, diagnosis and treatment of these disorders are urgently needed to identify and optimally treat affected patients. Though numerous challenges impact the progress of research in this area, specimens are needed to test new hypotheses and methodologies. We aim to create a registry and biorepository of tissue and fluid specimens for future studies.

The purpose of this study is to investigate the response rate of dietary therapy in patients with Eosinophilic Esophagitis (EoE) and determine rates of long-term compliance with the food elimination diets (SFED, FFED, step-up), and also to identify patient, clinical, and endoscopic factors that may be associated with increased rates of success in patients undergoing dietary therapy in EoE.

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 eosinophilic esophagitis (EoE), eosinophilic gastritis (EG), and eosinophilic colitis (EC) normally undergo endoscopy and/or colonoscopy (scope down the throat or up the bottom) where tissue specimens are collected for microscopic analysis. Treatments are then decided based on how the tissue looks. 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.
This study is being done to store blood cells, genetic material, blood serum and tissue biopsies so that they can be used in laboratory studies now and in the future to find causes of the rare disorder of mast cells and/or eosinophils and factors that may contribute to disease progression and treatment response.
