RESUMO
BACKGROUND: The patient perspective is essential for assessing disease severity, but it is not always adequately considered. We describe how a comprehensive clinical disease severity index (DSI) for inflammatory bowel disease (IBD) correlates with patient global self-assessment (PGSA). METHODS: In an individually linked parallel online survey, physicians provided the DSI, and patients provided self-assessed severity using a global question and visual analog scale (0-100) (PGSA). Mean DSI values by PGSA were calculated with 95% confidence intervals. Pearson correlation (r) and the intraclass correlation coefficient were calculated for PGSA vs DSI. Positive predictive values for identifying severe disease with PGSA categories as a reference were based on a threshold >22 points. RESULTS: The primary analysis included 89 pairs (46 Crohn's disease [CD], 43 ulcerative colitis [UC]) with strict criteria and 147 pairs when less stringent. Common reasons for exclusion were missing values for albumin or colonoscopy. Mean DSI values showed no clear trend with increasing PGSA in CD but good discrimination between moderate, severe, and very severe PGSA in UC. For PGSA on the visual analog scale, r was 0.54 for CD and 0.59 for UC (difference in means: CD 27.7, UC 13.8; intraclass correlation coefficient: CD 0.48, UC 0.58). A high DSI predicted severe disease in 76.2% of CD and 65.2% of UC. CONCLUSIONS: The DSI showed good discrimination for patient-reported disease severity in UC but performed unsatisfactorily in CD. Correlations were moderate. Further refinement of the DSI is suggested to better reflect the patient perspective.
The performance of an inflammatory bowel disease severity score was compared with self-perceived severity based on an individually linked online survey of patients and their physicians. Agreement and prediction of severe disease were moderate and should be improved by integrating the patients' perspective.
RESUMO
BACKGROUND AND AIMS: The course of Crohn's disease (CD) is highly variable. The Prospektive Evaluation eines Score zur Vorhersage eines milden Verlaufsbei neu diagnostizierten Morbus Crohn-Patienten in gastroenterologischen Fachpraxen (PROGNOS) study aimed to determine the frequency of a mild disease course and validate a proposed prediction score. METHODS: The PROGNOS study is a prospective study of CD patients who were newly diagnosed and, except for 1 course of 5-aminosalicylic acid or steroids for ≤10 days, therapy-naïve. Among other predefined inclusion criteria, the initial diagnosis had to be made ≤6 weeks before enrollment. All inception cohort patients were diagnosed and screened consecutively in participating gastroenterology practices in Germany specialized in inflammatory bowel disease. All screened CD patients were scored and, if possible, included in the study for up to 5 years (NCT02193048). RESULTS: A total of 201 CD patients were included in the study (43.3% male; mean age 33 years, mean follow-up 38 months). Altogether, 29.5% of the patients had a mild course at 36 months. Among those with a score ≤2, therapy escalation at 36 months was necessary for only 24.2%, whereas in the group with a score >2, therapy escalation was necessary for 70.2% of patients. In the Kaplan-Meier curve showing time to therapy escalation in the 2 groups, there was a pronounced and statistically significant divergence of the curves starting at 3 months and extending to 48 months (Pâ <â .001). CONCLUSIONS: In this prospective study, about 30% of incident CD patients had a mild disease course. Our suggested PreMiCC (prediction score for a mild course of Crohn's disease) successfully predicted this.
In our study of newly diagnosed Crohn's disease patients, we found that around 30% had a mild disease course. We also successfully tested our proposed PreMiCC (prediction score for a mild course of Crohn's disease), which predicts this mild course.
RESUMO
BACKGROUND: This observational real-world evidence (RWE) study is based on prospectively collected data from the VEDOIBD registry study. AIM: To compare the effectiveness of vedolizumab and anti-TNF agents in biologic-naïve 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 score; any switch to a different biologic agent was considered an outcome failure (modified ITT analysis). We used propensity score adjustment with inverse probability of treatment weighting to correct for confounding. RESULTS: During induction therapy, clinical remission was relatively low and similar in vedolizumab- and anti-TNF-treated patients (23% vs. 30.4%, p = 0.204). However, clinical remission rates after two years were significantly higher for vedolizumab-treated patients than those treated with an anti-TNF agent (43.2% vs. 25.8%, p < 0.011). Among patients treated with vedolzumab, 29% switched to other biologics, versus 54% who had received an anti-TNF agent. CONCLUSION: After two years of treatment, vedolizumab resulted in higher remission rates than anti-TNF agents.

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: Clinical phenotypes in inflammatory bowel disease (IBD) patients include ulcerative colitis (UC) and Crohn's disease (CD). Moreover, genetic aetiology studies suggest a continuum of phenotypes from exclusively ileal to left-sided colonic disease. PATIENTS AND METHODS: A nationwide registry (BioColitis Registry) prospectively recorded â¼900 UC-patients in Germany and in the CapColitis substudy, small bowel capsule endoscopy (SBCE) was consecutively offered at participating centres. The primary objective was to investigate the presence of small bowel lesions. In total, 127 UC-patients were included. RESULTS: SBCE was evaluable in 125 of 127 UC-patients. Small bowel lesions were found in 16/125 (13%) patients, of which nine were classified as clinically significant [backwash ileitis (n=4) or lesions suggestive of CD (n=5)], and seven were not significant [biopsy-induced lesions (n=3) or single small bowel lesions (n=4)]. The SBCE results prompted diagnostic workups in all patients with clinically relevant lesions, and all patients with lesions suggestive for CD (4%) were re-classified as CD by the treating physicians. CONCLUSION: Systematic examination of 125 consecutive UC-patients failed to confirm a clinically important phenotype overlap with CD, as suggested by genetic aetiology studies. In five patients (4%) with small bowel lesions, the diagnosis was changed to CD.

BACKGROUND/AIMS: Patients 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. METHODS: In 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. RESULTS: At 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. CONCLUSION: In 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.
