Rectal mucosal prolapse syndrome as an unusual gastrointestinal manifestation of Sjögren's syndrome: a case report.

Introduction: Rectal mucosal prolapse syndrome, histologically characterized by fibromuscular obliteration in the lamina propria, hyperplastic glands and thickened muscularis mucosa, causes rectal bleeding. Sjögren's syndrome is an autoimmune exocrinopathy that chiefly destroys the salivary and lacrimal glands by lympho-plasmacytic infiltration. Although various gastrointestinal manifestations have been reported in patients with Sjögren's syndrome, there have not been to our knowledge any case reports to date of rectal mucosal prolapse syndrome in association with Sjögren's syndrome.

Differential expression of leukocyte functions associated antigen-1 (LFA-1) on peripheral blood mononuclear cells in patients with Crohn's disease.

Background: The leukocyte function associated antigen-1 (LFA-1) intracellular adhesion molecule-1 pathway is presumed to play a pivotal role in the perpetuation of inflammatory bowel disease. We aimed to elucidate the effect of 2 different therapies on LFA-1 expression in patients with Crohn's disease (CD) and correlate LFA-1 expression with disease activity.

Methods: In all, 30 patients with active CD were recruited for the present investigation.

[Nonsteroidal anti-inflammatory drug-induced enteropathy and chronic nonspecific multiple ulcers of the small intestine].

With the development of double balloon endoscopy and video-capsule endoscopy, it has become inevitable for gastroenterologist to diagnose small intestinal ulcers accurately. Chronic nonspecific multiple ulcers of the small intestine (CNSU) and nonsteroidal antiinflammatory drugs-induced enteropathy (NSAIDs-enteropathy) share common clinicopathologic features characterized by histologically nonspecific ulcers and persistent blood loss. In addition, the two disorders had common enteroscopic findings, namely, circular ulcers and concentric stenoses.

Microcirculatory changes in experimental mesenteric longitudinal ulcers of the small intestine in rats.

Rats receiving intracolonic administration of indomethacin develop longitudinal ulcers on the mesenteric side of the small intestine that are similar to those seen in the acute phase of Crohn's disease. To investigate the causative role of microcirculatory disturbances and to elucidate the therapeutic effect of antioxidants on this enteropathy in rats, we serially evaluated changes in regional blood flow of the small intestine using laser Doppler perfusion imaging and the colored microsphere injection method. Both methods disclosed stepwise hyperperfusion limited to the mesenteric side of the small intestine following transient ischemia during the initial 30-60 minutes.

Blockade of tumor necrosis factor-alpha-converting enzyme improves experimental small intestinal damage by decreasing matrix metalloproteinase-3 production in rats.

Objective: Tumor necrosis factor (TNF)-alpha-converting enzyme (TACE), which has been purified, regulates maturity of TNF-alpha. Matrix metalloproteinases (MMPs) play a key role in various inflammatory conditions. The incidence of intestinal damage has increased, but the mechanism and treatment have not been well understood.

Endoscopic features of chronic nonspecific multiple ulcers of the small intestine: comparison with nonsteroidal anti-inflammatory drug-induced enteropathy.

Chronic nonspecific multiple ulcers of the small intestine (CNSU) and nonsteroidal anti-inflammatory drug-induced enteropathy (NSAID-enteropathy) share common clinicopathologic features characterized by histologically nonspecific ulcers and persistent blood loss. The aim was to compare enteroscopic findings between CNSU and NSAID-enteropathy. Four patients with CNSU and five patients with NSAID-enteropathy were examined by enteroscopies.

Treatment of ulcerative colitis patients by long-term administration of germinated barley foodstuff: multi-center open trial.

Germinated barley foodstuff (GBF), which mainly consists of dietary fiber and glutamine-rich protein, is a prebiotic for ulcerative colitis (UC). In our previous study, we carried out a clinical trial of GBF with mildly to moderately active UC patients and showed that GBF treatment was able to attenuate the symptoms of UC in a relatively short-term. The aim of this study was to investigate the efficacy of long-term administration of GBF in the treatment of UC in a multi-center open trial.

Treatment of ulcerative colitis by feeding with germinated barley foodstuff: first report of a multicenter open control trial.

Background: Germinated barley foodstuff (GBF) is a prebiotic foodstuff that effectively increases luminal butyrate production by stimulating the growth of protective bacteria. In the first pilot study, GBF has been shown to reduce both clinical activity and mucosal inflammation in ulcerative colitis (UC). The aim of this study was to investigate the efficacy of GBF in the treatment of UC in a multicenter open control trial.
