    OBJECTIVES To evaluate the psychometric properties of the Norwegian version of the multidimensional fatigue inventory (MFI-20) in patients with inflammatory bowel disease. METHODS Participants were recruited from nine hospitals in the southeastern and western parts of Norway. Clinical and sociodemographic data were collected, and participants completed the MFI-20, as well as the Fatigue Questionnaire (FQ). In addition to a confirmatory factor analysis, validity, reliability, test-retest and responsiveness were evaluated. RESULTS In total, 410 patients were included. The Norwegian MFI-20 had an acceptable model fit when compared to the original five-dimensional structure. A positive correlation was observed between the dimensions of MFI-20 and the FQ. MFI-20 scores increased according to subjective disease activity, but no differences were observed when using a calprotectin cut-off  =250 µg/g mg/kg. All MFI-20 dimensions except ‘reduced motivation’ in both ulcerative colitis (UC) and Crohn’s disease (CD) patients had alpha Cronbach alpha values ≥70, and test-retest reliability revealed good to excellent values. Merely one dimension (Reduced activity) in UC patients reporting improvement did not reach the threshold for acceptable responsiveness according to Guyatt statistics. CONCLUSIONS The Norwegian version of MFI-20 is valid, reliable and responsive. The instrument can safely be used in studies using fatigue as an endpoint.publishedVersio

    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. This study aimed to determine whether there is an association between vitamin D deficiency and severity of pain in patients with IBD, and to investigate the influence of other socio-demographic and psychological variables on the experience of pain. Methods: Patients with IBD were recruited from nine hospitals in Norway in a multicenter cross-sectional study. The Brief Pain Inventory (BPI) questionnaire was used to measure pain. Disease activity was assessed using clinical disease activity indices, C-reactive protein (CRP) and fecal calprotectin. Regression models were fitted to explore a possible association between 25-hydroxyvitamin D and pain severity. Results: Of 407 patients included in the analyses, 229 (56%) had Crohn's disease (CD) and 178 (44%) had ulcerative colitis (UC). Vitamin D deficiency was present in half (203/407) of patients. Presence of pain was reported by 76% (309/407). More severe pain was associated with female gender and increased disease activity scores, but not with increased CRP or fecal calprotectin. In CD, patients without prior intra-abdominal surgery reported more severe pain. In multivariate analyses, there was no association between 25-hydroxyvitamin D and pain severity. Conclusions: In this study, no significant association between pain severity and vitamin D deficiency was revealed in patients with IBD.publishedVersio

    BACKGROUND In celiac disease, small intestinal transglutaminase 2 causes deamidation of glutamine residues in gluten peptides, which enhances stimulation of T cells and leads to mucosal injury. Inhibition of transglutaminase 2 is a potential treatment for celiac disease. METHODS In a proof-of-concept trial, we assessed the efficacy and safety of a 6-week treatment with ZED1227, a selective oral transglutaminase 2 inhibitor, at three dose levels as compared with placebo, in adults with well-controlled celiac disease who underwent a daily gluten challenge. The primary end point was the attenuation of gluten-induced mucosal damage, as measured by the ratio of villus height to crypt depth. Secondary end points included intraepithelial lymphocyte density, the Celiac Symptom Index score, and the Celiac Disease Questionnaire score (for assessment of health-related quality of life). RESULTS Of the 41 patients assigned to the 10-mg ZED1227 group, the 41 assigned to the 50-mg group, the 41 assigned to the 100-mg group, and the 40 assigned to the placebo group, 35, 39, 38, and 30 patients, respectively, had adequate duodenal-biopsy samples for the assessment of the primary end point. Treatment with ZED1227 at all three dose levels attenuated gluten-induced duodenal mucosal injury. The estimated difference from placebo in the change in the mean ratio of villus height to crypt depth from baseline to week 6 was 0.44 (95% confidence interval [CI], 0.15 to 0.73) in the 10-mg group (P=0.001), 0.49 (95% CI, 0.20 to 0.77) in the 50-mg group (P<0.001), and 0.48 (95% CI, 0.20 to 0.77) in the 100-mg group (P<0.001). The estimated differences from placebo in the change in intraepithelial lymphocyte density were -2.7 cells per 100 epithelial cells (95% CI, -7.6 to 2.2) in the 10-mg group, -4.2 cells per 100 epithelial cells (95% CI, -8.9 to 0.6) in the 50-mg group, and -9.6 cells per 100 epithelial cells (95% CI, -14.4 to -4.8) in the 100-mg group. Use of the 100-mg dose may have improved symptom and quality-of-life scores. The most common adverse events, the incidences of which were similar across all groups, were headache, nausea, diarrhea, vomiting, and abdominal pain. Rash developed in 3 of 40 patients (8%) in the 100-mg group. CONCLUSIONS In this preliminary trial, treatment with ZED1227 attenuated gluten-induced duodenal mucosal damage in patients with celiac disease.publishedVersionPeer reviewe

    Clinical experience with infliximab biosimilar Remsima (CT-P13) in inflammatory bowel disease patients

    Many reference biological therapies have now reached or are near to patent expiry, and therefore a number of biosimilars have been or will be developed. The term biosimilar can be defined as a biotherapeutic product that is similar in efficacy, safety and quality to the licensed reference product. Biosimilars may lead to a reduced price and significant cost savings for the health community and hopefully more patients globally will have easier access to biological therapy when indicated. CT-P13, which is a TNF-alfa inhibitor, is the first monoclonal antibody biosimilar being used in clinical practice. The drug is approved for all indications as an innovator product although clinical efficacy has only been demonstrated in rheumatic diseases. Until now the number of patients with inflammatory bowel disease (IBD) treated with CT-P13 is confined, but experience is continuously growing. Based on current data, CT-P13 seems to be efficacious and generally well tolerated in IBD especially in patients who are naïve to biological therapy. Knowledge with regard to interchangeability between CT-P13 and the originator infliximab is however, still rather sparse and more data are desired. Immunogenicity and long-term safety related to CT-P13 are other areas of great importance and good and reliable postmarketing pharmacovigilance is therefore required in the coming years

    Background Treatment with biological agents such as anti-tumor necrosis factors (TNFs) has become standard of care in moderate to severe pediatric inflammatory bowel disease (IBD). However, a significant proportion of patients experience loss of response to anti-TNFs, need treatment escalation, or develop side effects. There is no data in the literature regarding combination of biological agents in pediatric IBD. Methods At our hospital, which is a tertiary referral center, we have combined the anti-TNF infliximab with either vedolizumab or ustekinumab in patients with severe pediatric IBD. The indications for dual biological therapy were insufficient efficacy of infliximab or vedolizumab monotherapy, or side effects such as psoriasis due to anti-TNFs. Results Eight patients (four boys) aged 14–17.5 years received a combination of infliximab and vedolizumab due to only a partial response to infliximab, four with Crohn’s disease (CD) and four with ulcerative colitis (UC). Clinical remission was achieved in four patients (3 UC) and four had a colectomy (3 CD, 1 UC). Five CD patients (3 girls) aged 11–17 years, on maintenance therapy with infliximab, developed psoriasis resistant to topical treatment. A combination of infliximab and ustekinumab resulted in clinical remission of CD without skin symptoms. No serious adverse events occurred in any of the patients on combination therapy. Thirteen publications report on combining biologicals, all in adult IBD. Conclusion In pediatric IBD, combining biological agents seems to be safe and beneficial in selected patients. The safety should be addressed in long-term follow-up studies

    Background: Iron deficiency and iron deficiency anaemia are common complications in inflammatory bowel disease (IBD). In patients with moderate‐to‐severe anaemia, oral iron intolerance or ineffectiveness of oral iron, ferric carboxymaltose and iron isomaltoside are widely used. Hypophosphatemia is a side effect of both preparations. Aims: To investigate the occurrence of hypophosphatemia in IBD patients with iron deficiency/iron deficiency anaemia treated with high‐dose intravenous iron. Methods: A prospective observational study of adult IBD patients with iron deficiency/iron deficiency anaemia was conducted at two study sites where patients received 1000 mg of ferric carboxymaltose or iron isomaltoside. At baseline, weeks 2 and 6, blood and faecal samples were collected. The primary endpoint was to determine the incidence of moderate‐to‐severe hypophosphatemia. Secondary endpoints included the total incidence of hypophosphatemia, possible risk factors for hypophosphatemia, and response to single‐dose intravenous iron. Results: One hundred and thirty patients were included. In the per‐protocol set, 52 patients received ferric carboxymaltose and 54 patients received iron isomaltoside. Ferric carboxymaltose treatment had a significantly higher incidence of moderate‐to‐severe hypophosphatemia compared with iron isomaltoside at week 2 (56.9% vs 5.7%, P < 0.001) and a higher incidence at week 6 (13.7% vs 1.9%, P = 0.054).The overall incidence of hypophosphatemia was significantly higher with ferric carboxymaltose compared with iron isomaltoside treatment at weeks 2 (72.5% vs 11.3%, P < 0.001) and 6 (21.6% vs 3.7%, P = 0.013). Conclusions: In IBD patients with iron deficiency/iron deficiency anaemia, ferric carboxymaltose was associated with higher incidence, severity and persistence of hypophosphatemia compared with iron isomaltoside. The presence of moderate‐to‐severe hypophosphatemia beyond 6 weeks is a clinical concern that requires further investigation

    Objectives Acute upper gastrointestinal bleeding is a well-recognized complication of peptic ulcers and erosions. The aim of this study was to assess the incidence rate and identify risk factors for this complication in southeastern Norway. Materials and methods Between March 2015 and December 2017, a prospective observational study was conducted at two Norwegian hospitals with a total catchment area of approximately 800,000 inhabitants. Information regarding patient characteristics, comorbidities, drug use, H. pylori status and 30-day mortality was recorded. Results A total of 543 adult patients were included. The incidence was 30/100,000 inhabitants per year. Altogether, 434 (80%) of the study patients used risk medication. Only 46 patients (8.5%) used proton pump inhibitors (PPIs) for more than 2 weeks before the bleeding episode. H. pylori testing was performed in 527 (97%) patients, of whom 195 (37%) were H. pylori-positive. The main comorbidity was cardiovascular disease. Gastric and duodenal ulcers were found in 183 (34%) and 275 (51%) patients, respectively. Simultaneous ulcerations at both locations were present in 58 (10%) patients, and 27 (5%) had only erosions. Overall, the 30-day mortality rate was 7.6%. Conclusions The incidence of upper gastrointestinal bleeding due to peptic ulcers and erosions was found to be lower than previously demonstrated in comparable studies, but the overall mortality rate was unchanged. The consumption of risk medication was high, and only a few patients had used prophylactic PPIs. Concurrent H. pylori infection was present in only one-third of the patients
