  2. 6. Neuro-immune regulation of macromolecular permeability in the normal human colon and in ulcerative colitis

    Author : Conny Wallon; Johan Dabrosin Söderholm; Peter Naredi; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Colitis; ulcerative; colon; sigmoid; cytology; immunohistochemistry; Gastroenterology; Gastroenterologi;

    Abstract : Background and aim: Persistent stress and life events affect the course of ulcerative colitis (UC) by largely unknown mechanisms. Regulation of epithelial permeability to antigens is crucial for the balance between inflammation and immuno-surveillance, and increased intestinal permeability has been shown in patients with ulcerative colitis.

  4. 7. Acute gastrointestinal graft-versus-host disease in allogeneic hematopoietic stem cell transplanted children and adolescents : clinical aspects of histopathological evaluation and risk factors

    Author : Thomas Mårtensson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Acute graft-versus-host disease (aGVHD), following allogeneic hematopoietic stem cell transplantation (HSCT), is a potentially life-threating condition. Gastrointestinal involvement of aGVHD (GI-aGVHD) affects approximately every fourth transplanted child. The diagnosis of GI-aGVHD is primarily symptom-based. READ MORE

  5. 8. Collagenous colitis : The influence of inflammation and bile acids on intestinal barrier function

    Author : Andreas Münch; Magnus Ström; Johan Söderholm; Magnus Simrén; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Background and aims: Collagenous colitis (CC) is a diarrheal disorder with an incidence rate of 5-6/100000 inhabitants, affecting mainly middle-aged women. The diagnosis is made by histology of the colonic mucosa. Classical findings are a thickened subepithelial collagenous layer and chronic inflammation in the lamina propria. READ MORE

    Abstract : There is a persisting controversy concerning the definition, etiology and pathogenesis of Barrett's esophagus. The dramatic and parallel increase in the incidence of esophageal and junctional adenocarcinoma over the past decades justifies an evaluation of the pathophysiology of premalignant metaplastic changes of the esophagus and the gastroesophageal junction.
