Abstract
Ileitis, or inflammation of the ileum, is often caused by Crohn's disease. However, ileitis may be caused by a wide variety of other diseases. These include infectious diseases, spondyloarthropathies, vasculitides, ischemia, neoplasms, medication-induced, eosinophilic enteritis, and others. The clin...

Abstract
Out of 334 patients, 39 (12%) were backwash ileitis-positive. Compared with backwash ileitis-negative patients, backwash ileitis-positive patients had a higher incidence of pancolitis (100% vs 74%; P = .0001), primary sclerosing cholangitis (15% vs 2%; P = .001) and high-level (>100 enzyme-linked im...

Abstract
In Spearman's correlation test the MRE score showed the strongest relationship with serum level of TNF-alpha type II receptor (r = 0.52, p < 0.001), correlating less significantly with IL-6 level (r = 0.37, p < 0.01) and CDAI (r = 0.40, p < 0.001). CONCLUSION: TNFalpha receptor type II shows better...

Abstract
We evaluated the role of the pro-inflammatory cytokine TNF-alpha on nitric oxide synthase (NOS) expression in indomethacin-induced jejunoileitis in rats. Jejunoileitis was induced in rats with subcutaneous injections of indomethacin (7.5 mg/kg) 24 h apart for two consecutive days, and animals were r...

Abstract
Our results showed that the indomethacin-induced intestinal injury was remarkably improved in Bach1-deficient mice. Histological examination showed that the area of injured lesion was decreased in Bach1-deficient mice compared to wild-type mice. Administration of indomethacin induced expression of i...

Abstract
We describe a case of a 19-year-old male who developed CMV infection of the terminal ileum while receiving immunosuppression for lupus nephritis. This was a distinctly unusual site of infection which clinically mimicked Crohn's ileitis. We note that reports of terminal ileal CMV infection have been...

Abstract
A 25-year-old woman was hospitalized repeatedly during a 5-year period due to abdominal pain, change in stool pattern, high CRP and leucocytosis. Ultrasound and small bowel examination showed oedema of terminal ileum, and morbus Crohn was initially suspected. A later ileocolonoscopy with biopsy and...

We analyzed genome-wide DNA methylation in the mouse ileum during chronic inflammation, aging, and cancer. We found that inflammation leads to aberrant DNA methylation in PcG target genes, with 70% of the approximately 250 genes methylated in the inflamed tissue being PcG targets in embryonic stem c...

Abstract
Salvinorin A as well as the KOR agonist U-50488 reduced motility in croton oil treated mice. The inhibitory effect of both salvinorin A and U-50488 was counteracted by the KOR antagonist nor-binaltorphimine and by the cannabinoid CB1 receptor antagonist rimonabant. Rimonabant, however, did not cou...

Abstract
A 19-year-old Japanese woman had melena 2 months after systemic lupus erythematosus was diagnosed. Colonoscopy showed diffuse ulceration with bleeding in the ileum, suggesting that the melena was due to ischemic enteritis associated with lupus enteritis. Because treatment with high doses of steroid,...

Abstract
All nine ATG16L1 gene variants analyzed displayed highly significant associations with CD demonstrating a CD-protective effect for the minor allele. The strongest associations were found for rs2241879 and the coding SNP rs2241880 (T300A); P= 3.6 x 10(-6) and 3.7 x 10(-6), respectively (OR 0.74, 95%...

Abstract
We demonstrate dynamic changes in the expression and functional state of CD44 on CD8+ T cells. These cells coexpress CD44 and L-selectin, giving them a surface phenotype similar to that of central memory T cells. Yet functionally they exhibit the phenotype of effector T cells, because they produce I...
