RESUMO
Eosinophil-associated diseases constitute a group of pathologies where eosinophils play an important role. Among them, eosinophilic gastroenteritis is a rare entity. Few demographic data exist in the literature, with an estimated prevalence of 28-30/100,000. The symptoms presented by patients mainly depend on the affected segment of the gastrointestinal tract and the layer infiltrated by eosinophils. We report a 22-year-old male patient with a one-month history of diarrhea, with mucus and occasionally hematic striae. Initial laboratory tests showed leukocytosis with eosinophilia, and imaging studies showed extensive involvement of the gastrointestinal tract characterized by diffuse concentric parietal thickening and submucosal edema associated with ascites. Upper endoscopy and biopsy confirmed the presence of foci of infiltration by eosinophils. The patient was treated with corticosteroids and a lactose and wheat free diet, with a favorable evolution, without relapse after stopping corticosteroid treatment.
Las enfermedades asociadas a eosinófilos constituyen un grupo de patologías en que el aumento de los eosinófilos presenta un rol fundamental, encontrándose entre ellas la gastroenteritis eosinofílica, entidad poco frecuente. En la literatura existen pocos datos demográficos, con una prevalencia estimada entre 28-30 /100.000 habitantes. Los síntomas dependen principalmente del segmento afectado del tracto gastrointestinal y de la capa de la pared infiltrada por eosinófilos. Se presenta el caso clínico de un paciente masculino de 22 años con cuadro de diarrea de un mes de evolución, asociado a mucosidad y ocasionalmente estrías hemáticas. El estudio de laboratorio inicial mostró leucocitosis con eosinofilia, realizándose estudios de imágenes que demuestran extenso compromiso del tubo digestivo caracterizado por engrosamiento parietal difuso concéntrico y edema submucoso del estómago como también de asas de intestino delgado, asociado a ascitis. La endoscopia digestiva alta y biopsia confirmaron la presencia de focos de infiltración por eosinófilos. El paciente fue tratado con corticoides y dieta con restricción de lactosa y trigo, con evolución favorable, sin recaída tras la suspensión del tratamiento corticoidal

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease of unknown etiology, probably immune-mediated. PSC is frequently associated with Inflammatory Bowel Disease, usually Ulcerative Colitis and less commonly with Crohn's disease. The small-duct PSC variant occurs in 5%of patients. Eosinophilic gastroenteritis (EG) is another chronic inflammatory disease, characterized by eosinophilic infiltration limited to the digestive tract, and probably of immunoallergic origin. EG is frequently observed in children but it's less commonly seen in adults. EG can affect any segment of the gastrointestinal tract, and recently it has been described an increase in the incidence of the esophagic variant, termed eosinophilic esophagitis.Ileocolonic involvement in EG is rare and clinical manifestations depend of the intestinal layer affected. Patients with mucosal infiltration complain of abdominal pain, fecal occult blood loss and/or protein-losing enteropaty, while signs and symptoms of obstruction are common in those with muscular EG, finally involvement of the serosal layer occurs in 10% and typically presents as eosinophil-rich ascitis. Response to steroids usually is excellent. There is a previous publication in the literature documenting the association of PSC and EG. Here we describe the first case of small-duct PSC associated to EG with ileocolonic involvement.
