Vedolizumab was effective for induction and maintenance of clinical and objective remission, both in Crohn's disease and ulcerative colitis.

Canada has one of the highest rates of inflammatory bowel disease (IBD) and the disease represents a significant health, social, and economic burden. There is currently no cure for IBD, although earlier diagnosis and new therapies have improved the overall health outcomes and quality of life for patients. Crohn's and Colitis Canada is Canada's only national, volunteer-based charity dedicated to finding cures for IBD and improving the lives of those affected, through research, education, patient programs, advocacy, and increased awareness. On April 30, 2015, Crohn's and Colitis Canada hosted the “Patient and Healthcare Professional Summit on the Burden of Disease in IBD” to obtain a deeper understanding of the unmet needs of IBD patients and their caregivers. Through personal vignettes, patients articulated a pressing need to increase understanding of the challenges faced by people suffering from IBD among both health care professionals and the general public, develop best practices for navigating life transitions and addressing the unique challenges faced by children with IBD, and provide equitable access to appropriate, effective, and affordable treatments. The recommendations that emerged from the summit will inform about efforts to increase public awareness, inform about advocacy strategies, and contribute to the development of research priorities.

The I-SCAN optical enhancement (OE) system with magnification is a recently introduced combination of optical and digital electronic virtual chromoendoscopy, which enhances mucosal and vascular details. The aim of this pilot study was to investigate the use of I-SCAN OE in the assessment of inflammatory changes in ulcerative colitis (UC). A total of 41 consecutive patients with UC and 9 control patients were examined by I-SCAN OE (Pentax Medical, Tokyo, Japan). Targeted biopsies of the imaged areas were obtained. A new optical enhancement score focusing on mucosal and vascular changes was developed. The diagnostic accuracy of I-SCAN OE was calculated against histology using two UC histological scores - Robarts Histopathology Index (RHI) and ECAP (xtent, hronicity,ctivity, lus additional findings). The overall I-SCAN OE score correlated with ECAP ( = 0.70; < 0.001). The accuracy of the overall I-SCAN OE score to detect abnormalities by ECAP was 80 % (sensitivity 78 %, specificity 100 %). I-SCAN OE vascular and mucosal scores correlated with ECAP ( = 0.65 and 0.71, respectively; < 0.001). The correlation between overall I-SCAN OE score and RHI was = 0.61 ( < 0.01), and the accuracy to detect abnormalities by RHI was 68 % (sensitivity 78 %, specificity 50 %). The majority of patients with Mayo 0 had abnormalities on I-SCAN OE. In UC, the new I-SCAN OE technology accurately identified mucosal inflammation, and correlated well with histological scores of chronic and acute changes.
