Background/aimsPatients with inflammatory bowel disease (IBD) need comprehensive, interdisciplinary and cross-sectoral health care. In Germany, evidence-based care pathways have been developed to improve the quality of care of IBD patients. We aimed to evaluate the effects of the implementation of some of these recommendations on patient-related outcomes.MethodsIn a region of North Germany, outpatients with IBD were recruited by gastroenterologists (intervention group). Three activities based on the recommendations of the IBD pathways were implemented, namely, 1) patient participation in a questionnaire-based assessment of 22 somatic and psychosocial problems combined with individualized care recommendations (patient activation procedure); 2) patient invitation to participate in a 2-day patient education program and 3) invitation to their gastroenterologists to participate in periodic interdisciplinary case conferences. For the control group, IBD patients receiving standard care at gastroenterology practices outside the specified region were recruited by their doctors. At baseline, 6- and 12-month follow-up, study patients were invited to complete questionnaires. Generic health-related quality of life, social participation and self-management skills were the main outcomes.ResultsAt baseline, 349 patients were included in the study (intervention group: 189; control group: 160); 142 patients from the former and 140 from the latter group returned completed questionnaires at the 12-month follow-up. Over time, improvement in health-related quality of life and social participation was similar in both groups. Participants of the intervention group demonstrated improved self-management skills and more often followed steroid-free medication regimens.ConclusionIn a real-world clinical context, patient activation procedure combined with patient education and case conferences was less effective than expected. The observed beneficial effects, however, encourage the evaluation of more intensive and addressee-centered activities.

Background: This observational real-world evidence (RWE) study is based on prospectively collected data from the VEDO IBD registry study. Aim:To compare the effectiveness of vedolizumab and anti-TNF agents in biologicnaïve patients with ulcerative colitis (UC) at the end of induction and during maintenance treatment.Methods: Between 2017 and 2020, we enrolled 512 patients with UC starting therapy with vedolizumab or an anti-TNF agent in 45 IBD centres across Germany. We excluded biologic-experienced patients and those with missing partial Mayo (pMayo) outcomes; this resulted in a final sample of 314 (182 on vedolizumab and 132 on an anti-TNF agent). The primary outcome was clinical remission measured using pMayo

Background and Aims: Patients with chronic inflammatory bowel disease (IBD) might have a higher prevalence of fructose malabsorption than healthy controls. This study’s aim was to determine the prevalence and symptom severity of fructose malabsorption in patients with active and inactive IBD. Methods: The present study was a multicenter noninterventional diagnostic pilot trial. Two hundred fifty-one participants were recruited from 12 outpatient clinics for internal medicine across Germany and from the University of Kiel. Fructose malabsorption was diagnosed by hydrogen breath testing. Patients diagnosed with bacterial overgrowth, non-H₂ producers, and patients who were tested positive for lactose malabsorption were excluded. Gastrointestinal symptoms during breath testing were evaluated using four-point subjective items to determine severity of bloating, abdominal pain, and diarrhea. Results: Two hundred five patients (45 with active IBD, 80 with IBD in remission, and 81 healthy controls) were analyzed. The number of patients diagnosed with fructose malabsorption – 35/44 (79.6%) in patients with active IBD, 59/80 (73.8%) inactive IBD, and 66/81 (81.5%) in healthy controls – did not differ between the groups (χ² [2, N = 205] = 1.48, p = 0.48). However, abdominal pain was more frequent in patients with active IBD than patients with IBD in remission (z = −2.936, p = 0.010), and diarrhea was more frequent in patients with active IBD than in healthy controls (z = 2.489, p = 0.038). Conclusions: Fructose malabsorption is not more common among patients with IBD than healthy subjects. However, the greater prevalence of patient-reported symptoms among patients with IBD may be of pathological and therapeutic relevance.

Background In this real-world-evidence (RWE) study we aimed to analyse the persistence of biologic therapy in biologic-naïve ulcerative colitis (UC) patients and to compare 1-year effectiveness of vedolizumab (VDZ) and anti-TNF. Methods Between 2017 and 2020, 1200 consecutively enrolled biologic-naïve and biologic- experienced patients with UC and Crohn′s disease (CD) were prospectively included in the VEDOIBD-Registry from 45 IBD-experienced centres across Germany. After exclusion of bio-experienced patients, CD and missing outcomes, the final sample consisted of 274 biologic-naïve UC-patients with 1-year follow-up data. Switchers of a drug were considered as treatment failure (modified intention-to-treat analysis; mITT) while switchers were excluded from per protocol analysis (PP). Clinical response modified (reduction of partial Mayo score (pMayo) from baseline to 1-year by >3 points or a reduction of at least 30% compared to baseline or reaching remission at 1-year) and (steroid-free) remission rates (pMayo ≤1 plus a bleeding subscore=0 (and no systemic use of steroids or budesonide at 1-year)) were predefined as outcomes. To reduce the effect of confounders, PS adjustment with inverse probability of treatment weighting (IPTW) was implemented. A weighted logistic regression was used, and the results were reported as odds ratio (OR) and 95% confidence interval (CI). Results 158 VDZ and 116 anti-TNF (ADA: 27.6%, IFX: 57.8%, GOL: 14.7%) biologic-naïve UC-patients were included in this prospective RWE comparing the effectiveness of VDZ vs anti-TNF. Until week 52 significantly more patients switched to another biologic-drug in the anti-TNF group than in the VDZ group (40.5% vs 16.5%; p<0.001) (Fig. 1). In mITT, clinical response at 1-year was significantly higher in VDZ than in anti-TNF treated patients (61.7% vs. 40.3%; OR 2.39 (95% CI 1.39–4.10)). VDZ also tended to be superior to anti-TNF for (steroid-free) remission (Tab. 1; p=0.058 (p=0.051)). In the PP-analysis, VDZ showed numerically higher 1-year effectiveness, but this did not reach statistical significance (Tab. 1). Analysing week-14 induction phase responders (Tab. 2), VDZ had numerically higher effectiveness rates compared to anti-TNF but without significant difference. Conclusion The 1-year maintenance findings suggested, in line with our previous induction phase data, only moderate long-term effectiveness in both groups. However, besides the significant response data, VDZ showed numerically higher remission rates compared to anti-TNF though only borderline significant. The higher treatment persistence of VDZ vs anti-TNF, along with the higher effectiveness, may suggest VDZ as a first-line biologic therapy option in UC patients.

Only a minority of patients with Crohn's disease or ulcerative colitis had adhered to the official recommendation concerning vaccination against H1N1. In order to reach higher acceptance, further vaccination campaigns must focus on the safety of the recommended vaccine.
