Ulcerative colitis: functional analysis of the in-depth proteome.

Background: Ulcerative colitis (UC) is one major form of inflammatory bowel disease. The cause and the pathophysiology of the disease are not fully understood and we therefor aim in this study to identify important pathophysiological features in UC from proteomics data.

Methods: Colon mucosa biopsies from inflamed tissue of untreated UC patients at diagnosis and from healthy controls were obtained during colonoscopy.

The sensitivity of fecal calprotectin in predicting deep remission in ulcerative colitis.

Background: Mucosal healing is proposed as treat-to-target in ulcerative colitis (UC), even though the definition of mucosal healing remains contested as it has been suggested to be assessed by either endoscopy, histology or both. However, all definitions require an endoscopic evaluation of the mucosa. As endoscopies are invasive and uncomfortable to the patient we aimed to calibrate noninvasive predictors of mucosal inflammatory status defined by both endoscopy and histology.
