Eosinophil-associated gastrointestinal disorders: A world-wide-web based registry

A world vide web database was established that tracked features of eosinophil-associated gastrointestinal disorders; 80% had coexisting atopic disease, 62% had food sensitization, and 16% had an immediate family member with a similar disorder. Developmental delay, seizure disorders, and congenital anomalies were seen in a proportion of respondents. The world wide web has proven to be an efficient tool to gather patient information, allowing us to define distinguishing features of various eosinophil-associated gastrointestinal disorders and to establish that these disorders have strong genetic and allergic components.
