Refractory neutrophils and monocytes in patients with inflammatory bowel disease after repeated bouts of prolonged exercise

A systematic review of the effect of structured exercise on inflammation and body composition in inflammatory bowel disease

PURPOSE

Given the substantial risk of treatment failure in inflammatory bowel disease (IBD), adjuvant therapies may play a role in disease management. We aim to carry out a systematic review to examine the effects of structured exercise on the inflammatory response in patients with IBD. Our secondary aim is to examine the effect of structured exercise programmes on body composition given both an increase in visceral obesity and the presence of sarcopenia have deleterious effects on outcomes in IBD.

METHODS

A systematic review was carried out following the Methodological Expectations of Cochrane Intervention Reviews (MECIR) manual and the Cochrane Handbook for Systematic Reviews of Interventions. Title/Abstract and MeSH Terms were used to search for relevant studies.

RESULTS

In total, 1516 records were screened for eligibility, and 148 records were reviewed for eligibility, of which 16 were included and a further 7 studies were identified from hand searching references. Four studies included body composition outcomes, and 14 studies reviewed the inflammatory response to exercise.

CONCLUSION

Further studies of adequate duration are required to include patients with more active disease to demonstrate an inflammatory response to exercise. Body composition measurements including muscle mass and visceral adiposity may play a key role in response to medical therapy in IBD and should be included as exploratory outcomes in future studies. A meta-analysis was not carried out due to the significant heterogeneity amongst studies.

An Irish Multi-Centre Study of Behaviours, Attitudes and Barriers to Exercise in Inflammatory Bowel Disease, a Survey from the Patient’s Perspective

Background: Physical activity (PA) in inflammatory bowel disease (IBD) has many potential favourable outcomes including anti-inflammatory effects, improvement in quality of life and improvements in patient body composition. It is recognised that patients with IBD have a significantly decreased exercise tolerance. Aim: 1. To assess physical activity levels, behaviours and barriers to PA in IBD. 2. To assess the likelihood of patients with IBD to engage in a community-based exercise programme. 3. To examine the presence of body image concerns in IBD. Method: Patient surveys were distributed in Beaumont and Connolly Hospitals between October and December 2021. Descriptive statistics, Chi-squared testing and Pearson’s correlations were completed using Minitab. p < 0.05 denoted statistical significance. Results: Data were recorded for a total of 203 patients. Out of all patients, 62% (n = 126) had Crohn’s disease (CD). Over half of the cohort were male (n = 115). Mean weight among females was 75 kg and 83 kg among males. Exercise behaviours: Out of all patients, 71% exercise regularly, on average for 59 min, 3.2 days/week. Walking was the most common form of PA (74%). A post-diagnosis change in exercise behaviour was found in 66% with three-quarters exercising less. The primary barrier to exercise was fatigue (54%). Female gender (p = 0.007) and age < 45 years (p = 0.02) were associated with body image dissatisfaction reported in 62% of patients. Conclusion: These data demonstrate the patient-reported impact of IBD on patient participation in PA. Concerns regarding body image were common and associated with gender and age. A feasibility study of a physician-derived exercise programme in patients with active IBD is underway in Beaumont Hospital to determine the effect on patient response to therapy, inflammation and body composition outcomes (NCT05174754).
