We assessed the effects of repeated prolonged moderate-intensity exercise on objective inflammatory markers in IBD patients. METHODS: In this study, IBD patients (IBD walkers, n = 18), and a control group (non-IBD walkers, n = 19), completed a 30, 40 or 50 km walking exercise on four consecutive days. Blood samples were taken at baseline and every day post-exercise to test for the effect of disease on exercise-induced changes in cytokine concentrations. A second control group of IBD patients who did not take part in the exercise, IBD non-walkers (n = 19), was used to test for the effect of exercise on faecal calprotectin. Both IBD groups also completed a clinical disease activity questionnaire. RESULTS: Changes in cytokine concentrations were similar for IBD walkers and non-IBD walkers (IL-6 p = .95; IL-8 p = .07; IL-10 p = .40; IL-1β p = .28; TNF-α p = .45), with a temporary significant increase in IL-6 (p

Background Many patients with IBD believe diet affects the course of disease and is at least as important as medication in their IBD treatment. However, easy assessment of patients’ food intake and structured support of a healthy diet are lacking. The Eetscore is an online tool which assesses diet quality and subsequently gives personal dietary advice. We used the Eetscore to assess diet quality of IBD patients, evaluated if diet quality improved over time and studied correlations with quality of life (QoL) and clinical disease activity. Methods A prospective cohort study with adult IBD patients was performed. Participants completed the Eetscore, the short IBDQ and a clinical disease activity questionnaire (P-HBI or P-SCCAI) at baseline and after 1 month. The Eetscore is a validated web-based screening tool to assess diet quality based on 16 food components (e.g. meat, vegetables, fruit and fish). It consists of a short Food Frequency Questionnaire and is scored with the Dutch Healthy Diet 2015-index based on the Dutch dietary guidelines. The score of each component ranges from 0 to 10, resulting in a total score between 0 and 160. Higher scores indicate better adherence to Dutch dietary guidelines. The Eetscore subsequently provides personalised dietary advice based on the assessment. We assessed changes over time using paired samples t-tests or McNemar’s test and correlations using Pearson’s or Spearman’s correlation. Results We included 212 participants. At time of this preliminary analysis, 175 participants (60% female, 49% Crohn’s disease) completed baseline and 1-month assessments. Their median age was 49 years [IQR 32–58], BMI 25 kg/m2 [IQR 22–28] and disease duration 10 years [IQR 4–18]. At baseline, mean Eetscore was 98 ± 19, with highest median scores (≥8.5) on red meat, fat and oils, sweetened beverages, alcohol and salt intake, and lowest median scores (≤5) on nuts, legumes, processed meat and unhealthy choices (Figure 1). Diet quality increased with 5.6 points (95%CI 3.7–7.5) to a mean Eetscore of 103 ± 21 (p Conclusion This study suggests the Eetscore is a useful tool to monitor and support a healthy diet in IBD patients. Diet quality improved significantly following personalised dietary advice of the Eetscore. Short term results did not indicate a correlation between diet quality and QoL or clinical disease activity.

Background Diet and physical activity might help to improve quality of life and maintain remission in patients with inflammatory bowel disease (IBD). In other conditions, interventions in which diet and physical activity are combined seem to be more effective than separate interventions. Therefore, we assessed the effect of a combined lifestyle intervention on the impact of disease on daily life, clinical disease activity, fatigue and quality of life in patients with Crohn’s disease (CD) or ulcerative colitis (UC). Methods A single arm intervention study was performed in IBD patients in remission or with mildly active disease. Participants received personal advice to improve their diet and level of physical activity by a dietician and a physiotherapist in one face-to-face and one telephone consult. These advices were supported by guidelines based on the Dutch dietary and physical activity guidelines, a recipe app and a booklet with physical activity exercises. IBD disability index (IBD-DI) to assess impact of disease on daily life, clinical disease activity questionnaires (P-HBI or P-SCCAI), IBD fatigue (IBD-F) patient self-assessment scale and IBD quality of life questionnaire (IBDQ) were completed. The Eetscore Food Frequency Questionnaire (Eetscore FFQ) and Short Questionnaire to Assess Health-enhancing physical activity (SQUASH) were used to assess diet and physical activity. Changes from baseline to 5 weeks after start were investigated by paired samples t-tests or Wilcoxon signed rank tests. Results We included 29 participants. At time of this preliminary analysis, 25 participants completed baseline and 5-week assessments (11 males, 11 CD, median age 36 years [IQR 29–53], median BMI 25 kg/m2 [IQR 24–28]). After 5 weeks, diet quality had significantly improved (p Conclusion These preliminary results suggest that a combined lifestyle intervention is effective to reduce fatigue and to increase quality of life in patients with IBD, at least in the short term. Impact of disease on daily life and clinical disease activity did not improve significantly. Participants reported their level of physical activity to be restricted due to COVID-19 measures, which could explain the lack of effect on this outcome. This study is still ongoing and we expect follow-up data up till 1 year after start.
