The use of serum calprotectin as a biomarker for inflammatory activity in inflammatory bowel disease.

Introduction: simple, reliable and non-invasive biomarkers are needed to enable the early detection of inflammatory activity for the correct management of inflammatory bowel disease (IBD). One of these biomarkers may be serum calprotectin (SC).

Material And Methods: a prospective study was performed of patients with IBD due to undergo a colonoscopy as part of the common clinical practice.

[Leukocytoclastic vasculitis associated with Crohn's disease].

In the course of inflammatory bowel disease (IBD) a number of extraintestinal manifestations are known to occur, being the dermatological ones often associated to both ulcerative colitis and Crohn's disease. Pyoderma gangrenosum and erythema nodosum are the most frequent, but there are other skin manifestations less frequently reported such as leukocytoclastic vasculitis. We present a case, in which Crohn's disease and leukocytoclastic vasculitis were simultaneously diagnosed, and corticoids treatment achieved complete remission of the both cutaneous and gastrointestinal manifestations.
