Gut homeostasis involves interrelated biological networks that include the immune system, specialized cells of the epithelium, such as Paneth and goblet cells, as well as triggers derived from the microbiota. Disruption of these homeostatic interactions may lead to the pathogenesis of inflammatory bowel diseases (IBD). To develop more targeted and individual treatments in Crohn's disease and ulcerative colitis, it becomes more and more important to link key mechanisms of the disease pathogenesis to distinct IBD subsets...

Biologic antagonists to tumor necrosis factor alpha (TNF- α) are effective medications and have become well established in the treatment of both Crohn's disease and ulcerative colitis. Biosimilar medications, which are medications deemed to be equivalent to reference biologic products in terms of clinical effectiveness, safety, pharmacokinetic analysis, and immunogenicity, have now been approved in inflammatory bowel diseases (IBD) based on indication exploration from clinical data in alternate disease states...

Biologic anti-tumor necrosis factor (TNF) drugs have demonstrated their efficacy for the treatment of ulcerative colitis. Nevertheless, some patients will not respond to this therapy or will develop loss of response. Leukapheresis is the main non-pharmacological therapy for some immune-mediated diseases. The aim of our study was to describe our experience with this therapy in ulcerative colitis patients after loss of response to anti-TNF treatment. Leukapheresis was indicated in four patients with left-sided or extensive colitis because of partial response to biological therapy or secondary loss of response to it...

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by periods of remission and periods of relapse. Patients often present with symptoms such as rectal bleeding, diarrhea and weight loss, and may require hospitalization and even colectomy. Long-term complications of UC include decreased quality of life and productivity and an increased risk of colorectal cancer. Mucosal healing (MH) has gained progressive importance in the management of UC patients. In this article, we review the endoscopic findings that define both mucosal injury and MH, and the strengths and limitations of the scoring systems currently available in clinical practice...

TNFα has a well-established role in inflammatory bowel disease that affects the gastrointestinal tract and is usually manifested as Crohn's disease or ulcerative colitis. We have compared Lactococcus lactis NZ9000 displaying TNFα-binding affibody with control Lactococcus lactis and with anti-TNFα antibody infliximab for the treatment of mice with dextran sulphate sodium (DSS)-induced colitis. L. lactis NZ9000 alleviated the colitis severity one week after colitis induction with DSS, more effectively when administered in preventive fashion prior to, during and after DSS administration...

Hepatosplenic T-cell lymphoma (HSTCL) is a rare and aggressive extranodal T-cell lymphoma that can arise in patients with underlying immune disorders. Others have suggested that tumor necrosis factor (TNF)-α inhibitor therapy for immune disorders increases the risk of HSTCL. To assess for a potential relationship between HSTCL and the use of TNF-α inhibitors, we searched for patients with HSTCL and underlying immune disorders at our institution. We identified 7 patients with a median age of 38 years. Five patients had Crohn disease, 1 ulcerative colitis, and 1 rheumatoid arthritis...

BACKGROUND: Biological therapies represent a fundamental innovation for the management of inflammatory bowel diseases (IBD). However, many biological originators have reached, or are about to reach, patent expiry and long-term therapy costs have become progressively unsustainable. CT-P13, a biosimilar of the anti-tumor necrosis factor (anti-TNF) monoclonal antibody infliximab, might represent a significant alternative to its originator, with the potential to decrease medical care costs and, therefore, become available to a large number of patients...

The use of thiopurines in inflammatory bowel disease (IBD) has been examined in numerous prospective, controlled trials, with a majority demonstrating a clinical benefit. We conducted this review to describe the historical and current evidence in the use of thiopurines in IBD. A systematic search was performed on MEDLINE between 1965 and 2016 to identify studies on thiopurines in IBD. The most robust evidence for thiopurines in IBD includes induction of remission in combination with anti-tumor necrosis factor (anti-TNF) agents, and maintenance of remission and post-operative maintenance in Crohn's disease...

Previous reports suggest a significant role for N-Methyl-D-aspartate (NMDA) activation in inflammatory processes. So, this study was conducted to investigate the effect of memantine, a commonly used NMDA receptor antagonist, on inflammatory changes in mice model of colitis. Colitis was induced by intracolonic instillation of trinitrobenzene sulfonic acid (TNBS) (40mg/kg). Animals received memantine (12.5, 25 and 50mg/kg, i.p.), glutamate (2g/kg, p.o.) or dexamethasone (1mg/kg, i.p.) 24h before TNBS instillation and daily thereafter for 4 days...
