Timing of proper introduction, optimization and maintenance of anti-TNF therapy in IBD: Results from a Delphi consensus

Background: Crohn's disease and ulcerative colitis are inflammatory bowel diseases (IBDs) with a rapidly growing worldwide incidence. The last decades presented rapid progress in pharmacological treatment leading in many cases to clinical and endoscopic remission, including biological treatment with anti-TNF agents. Aim: The exact timing of introduction, optimization and maintenance of anti-TNF therapy in IBDs is not thoroughly covered in current guidelines. Methods: We used the Delphi panel methodology to gather the IBD experts' views and achieve consensus for clinical recommendations on introducing and maintaining anti-TNF therapy for patients with IBDs. Results: Twelve recommendations achieved a high level of consensus in two assessment rounds by 52 (1st round) and 47 (2nd round) IBD experts. Conclusion: In many clinical situations, the early use of anti-TNF therapy is recommended. Nowadays, the cost-efficacy profile of anti-TNF biosimilars makes them the first-line drug in a substantial proportion of patients, thus providing the opportunity to increase access to biological therapy

Results from the 2nd Scientific Workshop of the ECCO (I): Impact of mucosal healing on the course of inflammatory bowel disease

AbstractOver the past years, mucosal healing has emerged as a major therapeutic goal in clinical trials in inflammatory bowel diseases. Accumulating evidence indicates that mucosal healing may change the natural course of the disease by decreasing the need for surgery and reducing hospitalization rates in both ulcerative colitis and Crohn's disease. Mucosal healing may also prevent the development of long-term disease complications, such as bowel damage in Crohn's disease and colorectal cancer in ulcerative colitis. Histologic healing may be the ultimate therapeutic goal in ulcerative colitis, whereas its impact on the course of Crohn's disease is unknown. Complete mucosal healing may be required before considering drug withdrawal. Targeting early Crohn's disease is more effective than approaches aimed at healing mucosa in longstanding disease. Several questions remain to be answered: should mucosal healing be systematically used in clinical practice? Should we optimize therapies to achieve mucosal healing? What is the degree of intestinal healing that is required to change the disease course? Large prospective studies addressing these issues are needed

Repeated oral co-exposure to yessotoxin and okadaic acid: A short term toxicity study in mice.

The polyethers yessotoxin (YTX) and okadaic acid (OA) are two marine algal toxins frequently associated as edible shellfish contaminants. Seafood contamination by these compounds, also at low concentrations and for a long period of time, can increase the possibility of their simultaneous and repeated ingestion, with possible synergistic toxic effects. Thus, in vivo toxicity by repeated oral exposure to a combination of fixed doses of YTX and OA (1 mg YTX/kg and 0.185 mg OA/kg, daily for 7 days) was investigated in mice, in comparison to that of each toxin alone. No mortality, signs of toxicity, diarrhea or hematological changes was induced by the toxins co-administration or by the single toxins. Light microscopy revealed changes at gastric level (multifocal subacute inflammation, erosions and epithelial hyperplasia) in 2/5 mice co-administered with the toxins. In animals dosed only with OA, epithelial hyperplasia of forestomach and slight focal subacute inflammation of its submucosa were noted. No changes were induced by the treatment with YTX. Ultrastructural analysis of the heart revealed some cardiomyocytes with "loose packing" of myofibrils and aggregated rounded mitochondria in mice co-administered with the toxins or with YTX; OA-treated mice showed only occasional mitochondrial assemblage and dilated sarcomeres. Thus, the combined oral doses of YTX (1 mg/kg/day) and OA (0.185 mg/kg/day) did not exert cumulative or additive toxic effects in mice, in comparison to the single toxins

Erratum: Corrigendum to “Expert consensus paper on the use of Vedolizumab for the management of patients with moderate-to-severe Inflammatory Bowel Disease” (Dig. Liver Dis. (2016) 48(4) (360–370))

In the last paragraph of Section 1, the sentence “VDZ is a monoclonal antibody blocking the α4β7 integrin which is selectively expressed by the vascular endothelium in the gastrointestinal tract [7]” should be replaced with: “VDZ is a monoclonal antibody blocking the α4β7 integrin which is selectively expressed by the activated GUT homing lymphocytes [7]”. Mariabeatrice Principi, Gastroenterology Section, Department of Emergency and Organ Transplantation, University of Bari, Bari, Italy, should have been listed in Appendix A (Members of the GIVI Study Group)

3rd European evidence-based consensus on the diagnosis and management of crohn's disease 2016: Part 2: surgical management and special situations

This paper is the second in a series of two publications relating to the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the diagnosis and management of Crohn's disease [CD] and concerns the surgical management of CD as well as special situations including management of perianal CD and extraintestinal manifestations. Diagnostic approaches and medical management of CD of this ECCO Consensus are covered in the first paper [Gomollon et al JCC 2016]

Expert consensus paper on the use of Vedolizumab for the management of patients with moderate-to-severe Inflammatory Bowel Disease

Crohn's Disease (CD) and Ulcerative Colitis (UC) are chronic, relapsing conditions resulting from uncontrolled inflammation of the intestinal mucosa. Both conditions are associated with significant disability and patients with CD face higher mortality rates compared to the general population. The increasing understanding of the immunological basis of the disease led to the introduction of biologic therapies targeting key pathways of the natural and adaptive immune response such as Tumor Necrosis Factor \u3b1 (TNF-\u3b1) inhibitors and, more recently, integrin-receptor antagonists. Treatment with TNF-\u3b1 inhibitors improved clinical and patient-reported outcomes for many patients who did not benefit from conventional therapy. However, a sizeable share of patients still face suboptimal outcomes due to primary or secondary therapy failure. With the introduction of VDZ, a biologic treatment targeting novel IBD-relevant biologic pathways, it is crucial to understand how to integrate such innovations into current clinical practice. To this end, a panel of 14 Italian experts in the management of IBD met for a roundtable discussion. Recommendations concerning the management of moderate-to-severe IBD based on experts' opinions and literature review are discussed in the present report
