Ulcerative colitis (UC) is generally described as a superficial diffuse inflammation restricted to the colon and rectum. However, several case reports have described a distinct and rare type of UC-related pan-enteritis, typically occurring after colectomy. Corticosteroids are effective for induction of remission of this condition, but it is not clear how these patients should be managed long term.

To further describe and define the entity of UC-related pan-enteritis and to investigate the efficacy of azathioprine for maintenance of remission.

We describe 5 patients with superficial diffuse ulcerative inflammation of the stomach, small bowel, and pouch if present. Four of the 5 patients developed enteritis after colectomy for ulcerative pancolitis. Pathology showed severe mucosal inflammation with infiltration of neutrophils and plasma cells from the stomach to the ileum. Video capsule endoscopy in 1 patient confirmed the presence of mucosal inflammation throughout the small bowel. All patients were started on a standardized treatment with intravenous corticosteroids for induction of remission and azathioprine for maintenance therapy. The conditions of all the patients rapidly improved, and subsequently, 4 patients were in full remission on azathioprine monotherapy, despite failure of this UC therapy before surgery, whereas 1 patient continues to have a steroid-dependent disease.

The outcomes of 5 cases of UC-related pan-enteritis as described in this report support a role for azathioprine in remission maintenance. Future research is needed to improve our understanding of this rare but distinct intestinal inflammatory disorder.

    ABSTRACT: While celiac disease is the most common cause of villous remodeling and intraepithelial lymphocytosis in the proximal small bowel, there are many entities that can mimic its histologic appearance. The purpose of this review is to discuss normal small bowel histology and the differential diagnosis of celiac disease. Approaches to evaluating for increased intraepithelial lymphocytes are presented, followed by a detailed discussion of the pathology of celiac disease. Particular emphasis is given to those conditions that cause an intraepithelial lymphocytosis in the setting of preserved villous architecture, although other important entities, such as peptic injury, idiopathic inflammatory bowel disease, medication injury, eosinophilic (allergic) gastroenteritis, autoimmune enteropathy, common variable immunodeficiency, and infections are also reviewed.

    ABSTRACT: The inflammatory bowel diseases (IBD) include Crohn's disease (CD) and ulcerative colitis. The disease may present at any age although the peak of presentation is the second and third decades of life. The incidences of these diseases are increasing around the world with the age of presentation getting younger. At present CD is incurable with colectomy being the treatment for severe UC. Although several pharmacological approaches are used to modulate the inflammatory response in IBD, few lead to histological healing and most have side effects. An alternative approach is to use enteral formulae given exclusively (EEN) to treat IBD. EEN requires the consumption of an elemental or polymeric formula, with the exclusion of all other nutrients, for a period of up to 12 weeks. The introduction of EEN as a therapeutic option for IBD was through prudent observation; however, EEN has become an established and reliable option for the treatment of paediatric IBD. Despite this, the mechanisms through which EEN induces disease remission are unknown and remain hypothetical. This review will discuss recent research into EEN both describing clinical features of EEN therapy and discussing the most up-to-date understanding of the mechanisms through which EEN may be reducing intestinal inflammation and inducing disease remission.

    ABSTRACT: Ulcerative colitis (UC)-associated pan-enteritis is a newly identified clinical entity that occurs almost exclusively after colectomy. Characterized by diffuse small bowel mucosal inflammation not compatible with Crohn's disease, the optimal treatment modality for this condition is unknown. Tacrolimus is a potent calcineurin inhibitor that has been successfully used in the treatment of UC. We describe a case of severe refractory pan-enteritis after colectomy for UC that was successfully treated with oral tacrolimus after failing intravenous corticosteroid treatment. Tacrolimus may be a safe and effective treatment modality for diffuse enteritis after colectomy in UC patients.
