Background: Eosinophilic granulomatosis with polyangiitis (EGPA) is a multisystem disorder characterised by chronic rhinosinusitis, asthma, and pronounced peripheral blood eosinophilia. The most commonly involved organ is the lung. However, EGPA can affect any organ system, including the cardiovascular, gastrointestinal, renal, and central nervous systems.

Efficacy and Safety of CT-P13 in Inflammatory Bowel Disease after Switching from Originator Infliximab: Exploratory Analyses from the NOR-SWITCH Main and Extension Trials.

Background: The NOR-SWITCH main and extension trials demonstrated that switching from originator to biosimilar infliximab (CT-P13) is efficacious and safe across six diseases. However, a subgroup analysis of Crohn's disease (CD) in the main trial displayed a close to significant difference favouring originator infliximab, and more scientific data have therefore been requested.

Objective: The aim was to assess treatment efficacy, safety, and immunogenicity in an explorative subgroup analysis in CD and ulcerative colitis (UC) in the NOR-SWITCH trials.

Pain Severity and Vitamin D Deficiency in IBD Patients.

: Pain and vitamin D deficiency are common in inflammatory bowel disease (IBD). Disease activity, fatigue, frequent relapses, prior surgery and psychological factors all seem to influence the experience of pain in IBD. Vitamin D deficiency has been associated with muscle and skeletal pain.

Fatigue is not associated with vitamin D deficiency in inflammatory bowel disease patients.

Aim: To investigate if vitamin D deficiency is associated with fatigue in patients with inflammatory bowel disease (IBD).

Methods: IBD patients were recruited from nine hospitals in the southeastern and western regions of Norway to participate in a multicenter cross-sectional study lasting from March 2013 to April 2014. Data were collected by interviews, from medical records and laboratory tests.

European Crohn's and Colitis Organisation Topical Review on Treatment Withdrawal ['Exit Strategies'] in Inflammatory Bowel Disease.

Clinically effective therapies now exist for remission maintenance in both ulcerative colitis [UC] and Crohn's Disease [CD]. For each major class of IBD medications [5-aminosalicyclates, immunomodulators, and biologic agents], used alone or in combination, there is a risk of relapse following reduction or cessation of treatment. A consensus expert panel convened by the European Crohn's and Colitis Organisation [ECCO] reviewed the published literature and agreed a series of consensus practice points.

Vitamin D deficiency in inflammatory bowel disease: prevalence and predictors in a Norwegian outpatient population.

Background And Aim: Vitamin D deficiency is common in inflammatory bowel disease (IBD). The aims of the present study were to determine the prevalence of vitamin D deficiency and to identify clinical and epidemiological variables associated with vitamin D deficiency in an outpatient population with IBD.

Methods: Participants were recruited from nine hospitals in the southeastern and western regions of Norway as part of an observational, multicentre study from March 2013 to April 2014.
