Figure 3From: Eosinophilic gastroenteritis with refractory ulcer disease and gastrointestinal bleeding as a rare manifestation of seronegative gastrointestinal food allergy Intestinal food-specific IgE concentrations in the patient with eosinophilic gastroenteritis. Endoscopically guided segmental lavage was performed at duodenum, mid jejunum, cecum and rectosigmoid according to the methods published previously [2, 5, 7]. Medians and 25–75% percentile are calculated from the values obtained at the four lavage sites. Food-specific IgE was measured by ThermoFischer Cap-System with significantly elevated levels of >0.35 KU/mg protein as reported from other investigators [3, 5, 7, 12, 15, 16]. Following allergens were negative with specific IgE titers <0.35 KU/mg protein: Egg white, caseine, lactalbumine, gliadin, rice, soy bean, soy Gly m4, potato, celery.Back to article page
