[Agammaglobulinemia and eosinophilic gastroenteritis].

The case is reported of a 34-year-old patient with diffuse eosinophilic gastroenteritis in connection with agammaglobulinaemia and B-cell defect. The syndrome was manifested by malabsorption, and gastrointestinal protein loss, complicated by temporary pyloric obstruction and duodenal ulceration. As in the case of sprue-like changes in the small intestinal mucosa, and nodular lymphoid hyperplasia, this diffuse eosinophilic gastroenteritis may be a reaction of the stomach and small intestine to immunological abnormalities.
