OBJECTIVE: Inflammatory bowel disease (IBD) patients experience problems at work resulting in work productivity loss driving indirect healthcare costs. We aimed to find determinants for work productivity loss in employed IBD patients while correcting for disease severity according to prior and active maintenance treatment. METHODS: In this longitudinal multicentre cohort study, 510 employed IBD patients completed online questionnaires during 18 months follow-up. Work productivity, fatigue and health-related quality of life (HRQL) were measured using the Work Productivity and Activity Impairment questionnaire, the Multidimensional Fatigue Inventory (score 20-100) and Short-Inflammatory Bowel Disease Questionnaire (score 10-70). Linear mixed model analyses including random, repeated and fixed effects were performed. RESULTS: Fatigue (β 0.22; 95% CI, 0.12-0.32) and reduced HRQL (β -1.15; 95% CI, -1.35 to -0.95) were the strongest determinants for work productivity loss in employed IBD patients. Clinical disease activity (β 9.50, 95% CI 6.48-12.51) and corticosteroid use (β 10.09, 95% CI 5.25-15.84) were associated with work productivity loss in the total IBD group and ulcerative colitis subgroup, but not in Crohn's disease patients. History of IBD-related surgery (β 9.41; 95% CI, 2.62-16.20) and vedolizumab use (β 12.74; 95% CI, 3.63-21.86) were significantly associated with work productivity loss in the ulcerative colitis subgroup. CONCLUSIONS: Fatigue and reduced HRQL were the strongest determinants for work productivity loss in employed IBD patients while correcting for disease severity and activity. These results underline the importance of monitoring fatigue and HRQL in routine care to reduce work productivity loss and indirect costs.

Supplemental Digital Content is available in the text., Background Patient reported outcomes are important in Crohn’s disease. In this prospective cohort, we investigated the performance of the Bristol Stool Form Scale (BSFS) and a visual analog scale (VAS) for abdominal pain as outcome measures in Crohn’s disease. Methods Patients with active Crohn’s disease starting glucocorticoids or anti-tumor necrosis factor were included. Before treatment and 10 weeks later we collected: clinical activity [Harvey Bradshaw Index (HBI) and Crohn’s-Disease-Activity-Index (CDAI)], serum C-reactive protein (CRP) and fecal calprotectin, and BSFS (1–7) and a 100-mm VAS based on a 7-day diary. Clinical response was defined as a reduction by at least 3 and at least 100 of HBI and CDAI, respectively. Fecal calprotectin-response and CRP-response were defined as reduction of at least 50%. Results Thirty-eight patients completed follow-up. At baseline, BSFS-parameters correlated more strongly with clinical activity (range: rs: 0.31–0.74) than with CRP (rs: −0.01 to 0.16) and fecal calprotectin (rs: 0.14–0.26). VAS scores correlated very weakly to moderately with clinical activity (rs: 0.18–0.45), and weakly to moderately with CRP (rs: 0.24–0.34) and fecal calprotectin (rs: 0.35–0.43). Changes in VAS scores correlated moderately to strongly (rs: 0.55–0.71) with changes in clinical activity, and weakly with changes in CRP and fecal calprotectin (rs: 0.21–0.35). Changes in BSFS parameters correlated weakly to moderately (rs: 0.23–0.53) with changes in clinical activity, and very weakly to weakly (rs: 0.01–0.35) with changes in CRP and fecal calprotectin. Responsiveness of VAS and BSFS was moderate to high (Guyatt’s statistic 0.41–2.17) and highly dependent on the definition of response. Conclusions The BSFS and a VAS appear to be responsive with moderate-to-strong construct validity to monitor patients with Crohn’s disease.

Objective Symptoms of irritable bowel syndrome (IBS) are common in inflammatory bowel disease (IBD) and are believed to reflect ongoing inflammation. Consequently, a low prevalence of IBS-type symptoms in IBD patients with normal inflammatory markers is expected. We aimed to investigate the prevalence of IBS-type symptoms in IBD patients in biochemical remission (evidenced by low fecal calprotectin levels) and the relationship of these symptoms with fecal calprotectin levels. Patients and methods In this observational, cross-sectional study, we included all adults with a history of IBD who had calprotectin levels less than 200 mu g/g during routine follow-up between August 2014 and May 2015 at our hospital. Patients were excluded if calprotectin was measured because of gastrointestinal complaints. All patients were approached by telephone to evaluate the presence of IBS-type symptoms using Rome III questionnaires. Patients fulfilling IBS criteria were subclassified according to bowel habits. Results In total, 74 patients were included; 33 (45%, 95% confidence interval: 34-56%) fulfilled the IBS criteria. A larger proportion of Crohn's disease patients with IBS-type symptoms had ileal disease compared with Crohn's disease patients without IBS symptoms (55 vs. 24%; P= 0.03). Other characteristics were similar between groups. No difference was found in calprotectin levels between patients with and without IBS-type symptoms (P= 0.91). The majority of patients with IBS-type symptoms had diarrhea-predominant or mixed-type IBS (64 and 27% of patients with IBS-type symptoms, respectively). Conclusion The prevalence of IBS-type symptoms in IBD patients in biochemical remission is high. A significant proportion of IBS-type symptoms is unrelated to ongoing inflammation and probably reflects 'true IBS'. Copyright (C) 2017 Wolters Kluwer Health, Inc. All rights reserved

Objective Infliximab maintenance treatment for Crohn's disease (CD) consists of intravenous infusions that are usually given at 6-8-week intervals. We aimed to evaluate whether home-based infliximab infusions could offer a useful and safe alternative for the management of CD patients. Methods Adult CD patients receiving infliximab maintenance treatment at the Academic Medical Center in Amsterdam were invited to receive their infusions at home for the duration of 1 year. Patients had to be in clinical remission and should have had no adverse events during previous infusions. Patient satisfaction and experience were studied. Costs were analyzed and compared with hospital-based infliximab infusions. Results Twenty-nine patients were invited, of whom 13 (45%) wanted to participate. Of the participants, 54% were female, and the median age was 33 years. In total, 59 infliximab infusions were administered at home at a median dose of 360 mg. The median rating of patient satisfaction was 8 on a scale from 1 to 10 for both home and hospital treatment settings. An important observation was that patients' willingness to participate would have been 70% if the possibility of receiving infusions at home outside office hours had been offered. Costs of infliximab infusions at home were €229 per infusion compared with €284 at the infusion clinic (excluding drug costs). Conclusion Home-based infliximab infusions were associated with a cost saving of €55 per infusion. Most participants were satisfied and would recommend home-based infusions to others. Infliximab treatment at home might be recommended as routine care for CD patients.

Cyclosporine and infliximab (IFX) seem equally effective as rescue therapy in hospitalized patients with severe ulcerative colitis (UC), although associated hospital stay and costs may differ. The aim of this study was to compare the duration of hospital stay and associated costs from initiation of rescue therapy to time of discharge in hospitalized patients with corticosteroid-refractory UC receiving cyclosporine or IFX. Colectomy rates after 6 months were used as the outcome parameter for treatment success. Hospital records of patients admitted between November 2003 and August 2012 at a tertiary referral center were analyzed. Forty-two patients were included (cyclosporine group: 26 patients; IFX group: 16 patients). Patient characteristics were comparable, with the exception that cyclosporine-treated patients more often had a pancolitis (89 vs. 63%, P=0.046). The median length of hospital stay was 11.0 (interquartile range 7.75-13.25) versus 4.0 days (interquartile range 4.0-5.75) in the cyclosporine and IFX group (P
