Abstract
BACKGROUND The bidirectional relationship between inflammatory bowel disease (IBD) flare-ups and depression/anxiety symptoms has prompted investigations into psychotherapy to improve health-related quality of life (HRQoL) by targeting depression and anxiety. Acceptance commitment therapy (ACT) is effective in improving symptoms of depression and anxiety in people with chronic diseases, yet minimal research has examined ACT's effectiveness for IBD. This study examines the feasibility, acceptability, and preliminary efficacy of the ACTforIBD program, an online program codesigned with consumers to deliver ACT to those with IBD. METHODS Adults with IBD and symptoms of mild-moderate distress were randomized to ACTforIBD or an active control (psychoeducation) condition. Participants completed 8 weekly, 1-hour sessions, 4 of which were therapist facilitated. Feasibility was based on recruitment and retention and acceptability was derived from postprogram satisfaction measures. Preliminary efficacy was determined by group differences in rate of change in study outcomes from baseline to postprogram. RESULTS Of 62 participants (89% women, 11% men; mean age 33 years), 55 completed the program (ACTforIBD: n = 26 [83.9%]; active control: n = 29 [93.5%]). Adherence and acceptability were high in the ACTforIBD group, with 80% of participants completing all self-directed modules and 78% of participants expressing satisfaction with the program. Significant and marginally significant group × time interactions were found for anxiety symptoms (b = -1.89; 95% confidence interval, -3.38 to -0.42) and psychological HRQoL (b = -0.04; 95% confidence interval, -0.07 to 0.01), showing decreased anxiety and increased psychological HRQoL in the intervention group. CONCLUSIONS ACTforIBD is feasible, acceptable, and improved anxiety symptoms, and psychological HRQoL. This highlights the need for a full-scale randomized controlled trial to further examine the program's efficacy.

Abstract
Objectives This study tested the acceptability and efficacy of an Acceptance and Commitment Therapy and compassion-based intervention (LIFEwithIBD) in people with IBD through a two-arm RCT. Methods Participants were recruited at the Gastroenterology Department of the Coimbra University Hospital between June and September 2019. Of the 355 patients screened, those who accepted to participate were randomly assigned to one of two conditions: experimental group (LIFEwithIBD; n = 25) or control group (waitlist; n = 29). Participants completed self-report measures at baseline (T0), post-intervention (T1), and 3-month (T2) and 12-month (T3) follow-ups. Intervention acceptability was assessed. Efficacy was examined using intent-to-treat ANCOVA at post-intervention after adjusting for baseline values of depressive, anxiety, and stress symptoms (primary outcomes). Linear mixed models for all longitudinal outcomes were also analysed. Inflammatory and disease biomarkers were determined at T0 and T3. Results Acceptability results revealed a high level of satisfaction and perceived usefulness regarding the intervention. Both groups experienced a significant decrease in stress symptoms and IBD symptom perception at T1. No significant differences were observed at follow-up for the primary outcomes. The experimental group reported significantly lower Crohn's disease Symptom severity at T2 than the control group. Post-hoc analyses designed to mitigate floor effects revealed substantial treatment effects for the experimental group regarding anxiety symptoms. No significant differences were observed in clinical biomarkers from T0 to T3. Conclusion The LIFEwithIBD intervention shows promising, although preliminary, benefits for managing disease activity and reducing anxiety symptoms in IBD patients with high severity of psychological distress.Clinical trial registration: https://www.clinicaltrials.gov/ct2/show/NCT03840707, identifier NCT03840707.

J Clin Med 2024; 13:1361. [PMID: 38592680 PMCID: PMC10932475 DOI: 10.3390/jcm13051361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 02/23/2024] [Accepted: 02/25/2024] [Indexed: 04/10/2024] Open
Abstract
Background: Inflammatory bowel diseases (IBDs) have seen an exponential increase in incidence, particularly among pediatric patients. Psychological stress is a significant risk factor influencing the disease course. This review assesses the interaction between stress and disease progression, focusing on articles that quantified inflammatory markers in IBD patients exposed to varying degrees of psychological stress. Methods: A systematic narrative literature review was conducted, focusing on the interaction between IBD and stress among adult and pediatric patients, as well as animal subjects. The research involved searching PubMed, Scopus, Medline, and Cochrane Library databases from 2000 to December 2023. Results: The interplay between the intestinal immunity response, the nervous system, and psychological disorders, known as the gut-brain axis, plays a major role in IBD pathophysiology. Various types of stressors alter gut mucosal integrity through different pathways, increasing gut mucosa permeability and promoting bacterial translocation. A denser microbial load in the gut wall emphasizes cytokine production, worsening the disease course. The risk of developing depression and anxiety is higher in IBD patients compared with the general population, and stress is a significant trigger for inducing acute flares of the disease. Conclusions: Further large studies should be conducted to assess the relationship between stressors, psychological disorders, and their impact on the course of IBD. Clinicians involved in the medical care of IBD patients should aim to implement stress reduction practices in addition to pharmacological therapies.

Do interventions for mood improve inflammatory biomarkers in inflammatory bowel disease?: a systematic review and meta-analysis. EBioMedicine 2024; 100:104910. [PMID: 38272759 PMCID: PMC10878994 DOI: 10.1016/j.ebiom.2023.104910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 11/23/2023] [Accepted: 11/28/2023] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND Psychoneuroimmunological mechanisms and the gut-brain axis appear relevant to disease activity and progression in Inflammatory Bowel Disease (IBD). A recent review showed no effect of psychological therapies on self-reported disease activity in IBD. This meta-analysis aims to establish whether interventions targeting mood outcomes (e.g., depression, anxiety and stress) impact inflammation levels in IBD and possible moderators of these effects. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. We searched five electronic databases and included randomised controlled trials where interventions targeted mood and assessed inflammatory outcomes pre- and post-intervention in adults with IBD. Independent reviewers screened studies, extracted data, and assessed methodological quality. Data were pooled to estimate standardised mean differences (SMDs) with 95% Confidence Intervals (CIs). A random-effects robust variance estimation accounted for studies measuring multiple biomarkers. Intervention type, mood as a primary or secondary outcome, effect on mood outcomes and IBD subtype were investigated as treatment effect moderators. Where there were sufficient biomarkers, individual meta-analyses were run (Pre-registration PROSPERO: CRD42023389401). FINDINGS 28 RCTs involving 1789 participants met inclusion criteria. Interventions demonstrated small, statistically significant effects on biomarkers (-0.35, 95% CI: -0.48, -0.22, p < 0.001) and medium effects on mood outcomes (-0.50, 95% CI: -0.73, -0.27, p < 0.001), without evidence of substantive heterogeneity or publication bias. Individual analyses showed small effects for improved faecal calprotectin (-0.19, 95% CI: -0.34, -0.03, p = 0.018) and C-Reactive Protein (-0.29, 95% CI: -0.47, -0.10, p = 0.002). Effect sizes were larger for psychological therapy interventions (compared with exercise or antidepressants) and when there was an effect (SMD ≥0.2) on mood. INTERPRETATION Treatments which address mood outcomes have beneficial effects on generic inflammation as well as disease-specific biomarkers (faecal calprotectin and C-Reactive Protein). Psychological interventions and interventions with larger treatment effects on mood accentuated the effect on biomarkers. More research is required to understand the biological or behavioural mechanisms underlying this effect.

Abstract
Background: We aimed to compare the effectiveness of mindfulness-based stress reduction and compassion-focused on the cognitive regulation of emotion in patients with irritable bowel syndrome (IBS). The research method was the semi-experimental type, with pre-test, post-test, follow-up, and experimental and control groups. Methods: The population included patients with IBS in Isfahan city; 45 of them were selected by convenience sampling method and randomly assigned to 3 groups (15 in each group). Then, the patients of one experimental group received eight sessions of 90 minutes of a mindfulness-based stress reduction program, while the other experimental group received eight sessions of 90 minutes of compassion-focused therapy. The measurement tools included the Cognitive Emotion Regulation Questionnaire (Garnefski and Kraaij, 2002) and a short clinical interview. Research data were analyzed using variance analysis with repeated measures on one factor (mixed design). Results: Both intervention methods were equally effective in changing the cognitive regulation of adaptive emotion mean scores (P<0.01), but the effect of compassion-focused therapy on improving the mean scores of cognitive regulation of adaptive emotion was more than mindfulness-based stress reduction therapy (P<0.05). Conclusion: It was concluded that both intervention methods can be used as complementary treatment for patients with IBS.

Abstract
Background This pilot study aims to test the usability of the iACTwithPain platform, an online ACT-based intervention for people with chronic pain, to obtain information on which intervention and usability aspects need improvement and on expected retention rates. Methods Seventy-three Portuguese women with chronic pain were invited to complete the first three sessions of the iACTwithPain intervention assess their quality, usefulness and the platform’s usability. Twenty-one accepted the invitation. Additionally, eight healthcare professionals working with chronic medical conditions assessed the platform and the intervention from a practitioner’s point of view. Results This study presented a considerable attrition rate (71.43%) among chronic pain participants, with six completers. There were no significant differences in demographic or clinical variables between dropouts and completers except for completed education (participants who dropped out presented less education than completers). Reasons for dropout were related to difficult personal events occurring during the time of the intervention, lack of time, or having forgotten. There seemed to be an overall satisfaction with both the intervention, its contents and form of presentation of information, and the platform, concerning its design, appearance, and usability. Real image videos were preferred over animations or audio by chronic pain participants. Healthcare professionals emphasized the appealing and dynamic aspects of the animation format. Conclusion This study informs the ongoing improvement of the iACTwithPain platform and provides valuable information on aspects researchers should consider while developing online psychological interventions for chronic pain. Further implications are discussed.

Abstract
INTRODUCTION Inflammatory bowel disease (IBD) involves an abnormal immune response to healthy gut bacteria. When a person develops IBD, their susceptibility to anxiety and/or depression increases. The ACTforIBD programme, specifically designed for people with IBD and comorbid psychological distress, draws on acceptance and commitment therapy (ACT), which promotes acceptance of situations that cannot be solved such as persistent physical symptoms. There are no ACT trials for IBD using an active control group or a telemedicine approach, which is important to improve accessibility, particularly in the context of the ongoing COVID-19 pandemic. The ACTforIBD programme is administered online with a 4-hour therapist involvement per participant only; if successful it can be widely implemented to improve the well-being of many individuals with IBD. METHODS AND ANALYSIS Our team have codesigned with consumers the ACTforIBD programme, an 8-week intervention of 1-hour sessions, with the first three sessions and the last session delivered one-to-one by a psychologist, and the other sessions self-directed online. This study aims to evaluate the feasibility and preliminary efficacy of ACTforIBD to reduce psychological distress in patients with IBD. Using a randomised controlled trial, 25 participants will be randomised to ACTforIBD, and 25 patients to an active control condition. ETHICS AND DISSEMINATION This protocol has been approved by Deakin University Research Ethics Committee in September 2021 (Ref. 2021-263) and the New Zealand Central Health and Disability Ethics Committee in December 2021 (Ref. 2021 EXP 11384). The results of this research will be published in peer-reviewed journals and shared with various stakeholders, including community members, policy-makers and researchers, through local and international conferences.
