Comprehensive Lifestyle Modification Influences Medium-Term and Artificially Induced Stress in Ulcerative Colitis-A Sub-Study within a Randomized Controlled Trial Using the Trier Social Stress Test

Psychological interventions for treatment of inflammatory bowel disease

BACKGROUND

Persons with inflammatory bowel disease (IBD) have an increased risk of suffering from psychological problems. The association is assumed to be bi-directional. Psychological treatment is expected to improve quality of life (QoL), psychological issues and, possibly, disease activity. Many trials have tested various psychotherapy approaches, often in combination with educational modules or relaxation techniques, with inconsistent results.

OBJECTIVES

To assess the effects of psychological interventions on quality of life, emotional state and disease activity in persons of any age with IBD.

SEARCH METHODS

We searched Web of Science Core Collection, KCI-Korean Journal Database, Russian Science Citation Index, MEDLINE, Psyndex, PsycINFO, Embase, Cochrane Central Register of Controlled Trials, and LILACS from inception to May 2023. We also searched trial registries and major gastroenterological and selected other IBD-related conferences from 2019 until 2023.

SELECTION CRITERIA

Randomized controlled trials of psychological interventions in children or adults with IBD compared to no therapy, sham (i.e. simulated intervention), or other active treatment, with a minimum follow-up time of two months, were eligible for inclusion, irrespective of publication status and language of publication. Interventions included psychotherapy and other non-pharmacological interventions addressing cognitive or emotional processing, patient education, or relaxation techniques to improve individual health status.

DATA COLLECTION AND ANALYSIS

Two raters independently extracted data and assessed the study quality using the Risk of Bias 2 Tool. Pooled standardized mean differences (SMD) for continuous outcomes and relative risks (RR) for event data were calculated with 95% confidence intervals (CI), based on separate random-effects models by age group, type of therapy and type of control. An SMD of 0.2 was considered a minimally relevant difference. SMD ≥ 0.4 was considered a moderate effect. Group analyses were planned to examine differential effects by type of IBD, disease activity, psychological comorbidity, therapy subtype, and treatment intensity. Statistical heterogeneity was determined by calculating the I2 statistic. Publication bias was assessed by presenting a funnel plot and calculating the Eggers Test. GRADE Profiling was used to describe the certainty of the evidence for relevant results.

MAIN RESULTS

Sixty-eight studies were eligible. Of these, 48 had results reported in sufficient detail for inclusion in the meta-analyses (6111 adults, 294 children and adolescents). Two trials were excluded from the meta-analysis following sensitivity analysis and tests for asymmetry because of implausible results. Most studies used multimodular approaches. The risk of bias was moderate for most outcomes, and high for some. The most common problems in individual trials were the inability to blind participants and investigators and outcome measures susceptible to measurement bias. The main issues leading to downgrading of the certainty of the evidence were heterogeneity of results, low precision and high or moderate risk of bias in the included trials. Publication bias could not be shown for any of the inspected analyses. In adults, psychotherapy was slightly more effective than care-as-usual (CAU) in improving short-term QoL (SMD 0.23, 95% CI 0.12 to 0.34; I2 = 13%; 20 trials, 1572 participants; moderate-certainty), depression (SMD -0.27, 95% CI -0.39 to -0.16; I2 = 0%; 16 trials, 1232 participants; moderate-certainty), and anxiety (SMD -0.29, 95% CI -0.40 to -0.17; I2 = 1%; 15 studies, 1135 participants; moderate-certainty). The results for disease activity were not pooled due to high heterogeneity (I2 = 72%). Interventions which used patient education may also have small positive short-term effects on QoL (SMD 0.19, 95% CI 0.06 to 0.32; I2 = 11%; 12 trials, 1058 participants; moderate-certainty), depression (SMD -0.22, 95% CI -0.37 to -0.07; I2 = 11%; 7 studies, 765 participants; moderate-certainty) and anxiety (SMD -0.16, 95% CI -0.32 to 0.00; I2 = 10%; 6 studies, 668 participants; moderate-certainty). We did not find an effect of education on disease activity (SMD -0.09, 95% CI -0.28 to 0.10; I2 = 38%; 7 studies, 755 participants; low-certainty). Pooled results on the effects of relaxation techniques showed small effects on QoL (SMD 0.25, 95% CI 0.08 to 0.41; I2 = 30%; 12 studies, 916 participants; moderate-certainty), depression (SMD -0.18, 95% CI -0.35 to -0.02; I2 = 0%; 7 studies, 576 participants; moderate-certainty), and anxiety (SMD -0.26, 95% CI -0.43 to -0.09; I2 = 13%; 8 studies, 627 participants; moderate-certainty). Results for disease activity were not pooled due to high heterogeneity (I2 = 72%). In children and adolescents, multimodular psychotherapy increased quality of life (SMD 0.54, 95% CI 0.06 to 1.02; I2 = 19%; 3 studies, 91 participants; moderate-certainty). The results for anxiety were inconclusive (SMD -0.09; 95% CI 0.-64 to 0.46; 2 trials, 51 patients, very low-certainty). Pooled effects were not calculated for depressive symptoms. Disease activity was not assessed in any of the trials compared to CAU. In education, based on one study, there might be a positive effect of the intervention on quality of life (MD 7.1, 95% CI 2.18 to 12.02; 40 patients; low-certainty evidence) but possibly not on depression (MD -6, 95% CI -12.01 to 0.01; 41 patients; very low-certainty). Anxiety and disease activity were not assessed for this comparison. Regarding the effects of relaxation techniques on children and adolescents, all results were inconclusive (very low-certainty).

AUTHORS' CONCLUSIONS

Psychological interventions in adults are likely to improve the quality of life, depression and anxiety slightly. Psychotherapy is probably also effective for improving the quality of life in children and adolescents. The evidence suggests that psychological interventions may have little to no effect on disease activity. The interpretation of these results presents a challenge due to the clinical heterogeneity of the included trials, particularly concerning the type and various components of the common multimodular interventions. This complexity underscores the need for further research and exploration in this area.

Lifestyle Intervention Modulates the CD4+ T Cell Profile in the Blood of Crohn's Disease Patients

BACKGROUND

Crohn's disease (CD) significantly affects patients' well-being and is influenced by stress and lifestyle factors, highlighting the importance of improving quality of life in CD management. An imbalance between pro- and anti-inflammatory CD4+ T cell responses is a key factor in CD, and stress has been shown to alter the function of CD4+ T cells. Therefore, this study aimed to evaluate the effect of a mind-body medicine stress management and lifestyle modification (MBM) program on the CD4+ T cell profile in CD patients.

METHODS

Circulating CD4+ T cells from CD patients were analyzed by flow cytometry following the MBM program. Patients were randomly assigned to either a guided intervention group (IG) or a self-guided waitlist control group (CG) over a 9-month trial and compared with healthy blood donors.

RESULTS

Lifestyle intervention reduced regulatory T cell (Treg) frequencies in the blood of CD patients. Notably, we observed a significant correlation between the quality of life improvement and Treg frequencies in the IG but not in the CG. Furthermore, differential activation and expression of the gut-homing molecules G protein-coupled receptor 15 and CCR9 on circulating Tregs and CD4+ effector T cells were detected in both the IG and CG.

CONCLUSIONS

The MBM program, whether guided or self-directed, has the potential to restore the CD4+ T cell profile of CD patients to levels comparable to healthy blood donors. Lifestyle interventions may benefit CD progression, symptoms, and immunological status, but further analysis is needed to substantiate these findings and to fully understand their clinical implications.

The Effect of Lifestyle Interventions on Anxiety, Depression and Stress: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

BACKGROUND/OBJECTIVES

Depression, anxiety, and stress are common mental health issues that affect individuals worldwide. This systematic review and meta-analysis examined the effectiveness of various lifestyle interventions including physical activity, dietary changes, and sleep hygiene in reducing the symptoms of depression, anxiety, and stress. Using stress as an outcome and conducting detailed subgroup analyses, this study provides novel insights into the differential effects of lifestyle interventions across diverse populations.

METHODS

Five databases were systematically searched: PubMed, Web of Science, Scopus, Cochrane Library, and Google Scholar, for gray literature searches. Keywords were used to search each database. The search period was from the conception of the databases until August 2023 and was conducted in English. For each analysis, Hedges' g was reported with a 95% confidence interval (CI) based on the random-effects method. Subgroups were analyzed and heterogeneity and publication bias were examined.

RESULTS

Ninety-six randomized clinical trial studies were included in this meta-analysis. Lifestyle interventions reduced depression (Hedges g -0.21, 95% confidence interval -0.26, -0.15; p < 0.001; I2 = 56.57), anxiety (Hedges g -0.24, 95% confidence interval -0.32, -0.15; p < 0.001; I2 = 59.25), and stress (-0.34, -0.11; p < 0.001; I2 = 61.40).

CONCLUSIONS

Lifestyle interventions offer a more accessible and cost-effective alternative to traditional treatments and provide targeted benefits for different psychological symptoms.

Evaluation of a Multimodal Stress Management and Comprehensive Lifestyle Modification Program on Quality of Life and Gastrointestinal Symptoms in Patients with Crohn's Disease: A Randomized Controlled Pilot Trial with 9-Month Follow-Up

INTRODUCTION

Stress and lifestyle factors impact the course of Crohn's disease (CD). Our primary objective was to assess whether patients with CD benefit from a mind-body-medicine stress management and lifestyle modification (MBM) program.

METHODS

This 9-month two-arm pilot trial was conducted in Bamberg, Germany (2020-2021). Patients (18-75 years) with mild to moderate activity of CD and stable medication were enrolled and randomly assigned to either a 10-week MBM program (intervention group, IG) or a single 90-min education session (waiting list control group, CG). Primary endpoints were quality of life (IBDQ) and disease activity (HBI). Secondary endpoints were emotional distress, core self-evaluation, and inflammatory biomarkers 3 and 9 months after baseline assessment.

RESULTS

We analyzed data from 37 patients (IG: n = 19, mean ± SD age 49.6 ± 13.1 years, 68% female; CG: 18, 46.8 ± 11.4, 67% female). Immediately after the intervention, 79% (IG) and 44% (CG) experienced a clinically relevant improvement (IBDQ score ≥16 points). This was similar after 9 months (63% vs. 44%). There was no difference in disease activity (3 months: p = 0.082, 95% CI -1.3 to 2.6; 9 months: p = 0.251, 95% CI -1.2 to 2.5). Secondary outcomes indicated improvements in emotional distress, core self-evaluation, erythrocyte sedimentation rate after three and in emotional distress, T-cell profiling in the blood, and fecal lactoferrin and calprotectin group after 9 months in the IG.

CONCLUSION

Our study suggested benefits of a multimodal stress management and lifestyle modification program for patients with CD. Larger trials are needed to determine if the program can supplement or at least partially replace pharmacological treatment approaches.

Mind-body-medicine and comprehensive lifestyle-modification in patients with Crohn's disease—Feasibility of a randomized controlled trial under pandemic circumstances

Introduction

Mind-body medicine (MBM) focuses on stress reduction and lifestyle changes. The primary objective of this pilot trial was to test study feasibility of a complex integrative MBM program for patients with Crohn's disease (CD), especially in rural regions, and under pandemic conditions.

Methods

Patients were stratified and randomized to the intervention group (IG) or the control group (CG). The intervention included a weekly 6-h session for 10 weeks. The CG (waiting list) received an initial 90-min workshop and started the intervention 9 months later. The primary outcome for study feasibility was recruitment and retention rates, as well as reasons for drop-out. The trial took place in Bamberg, Germany (September 2020 to December 2021).

Results

Totally 700 members of the German Crohn's and Colitis Organization—DCCV—were contacted. A total of 15% (102/700; 95% CI 12–17%) expressed interest to participate. Following screening, 41% (95% CI 32–50) were randomized to IG (n = 22) and CG (n = 20). The patients were on average (±standard deviation) 48 ± 13 years old, 67% were female, and have been suffering from CD for 20 ± 12 years. Patients traveled 71.5 ± 48.7 km (range: 9–227 km) to the intervention with no differences between IG and CG. At the 6-month follow-up, 36/42 (86%, 95% CI 74–95%) participants completed final assessment and 19/22 (86%, 95% CI 70–100%) the intervention. The most important reasons for non-responding were work-related (12/60; 20%) and for or drop-out pandemic-related anxiety (3/6). No patient and staff member became infected with SARS-CoV-2 during the study.

Conclusion

The feasibility of the MBM study was confirmed in terms of predefined recruitment and retention criteria, both despite difficult conditions (including the rural setting) and patients' fears associated with the pandemic. It was crucial to develop appropriate hygiene and safety concepts that enable chronically ill patients to participate in helpful group-based interventions even under pandemic conditions.

Multimodal stress reduction and lifestyle modification program for patients with ulcerative colitis: a qualitative study

BACKGROUND

Over 2 million people in Europe are affected by ulcerative colitis, which often severely impacts the quality of life of those concerned. Among other factors, lifestyle and psychosocial factors seem to play an important role in pathogenesis and course of the disease and can be addressed as a complement to pharmacotherapy in comprehensive lifestyle modification programs.

METHODS

This qualitative study as part of a mixed methods approach was carried out in the framework of a randomized controlled trial that examined the effect of a comprehensive lifestyle-modification-program (10-week-day clinic program) on quality of life in patients with ulcerative colitis. Qualitative interviews were conducted with 20 out of 47 patients of the intervention group after the program. The aim was to deepen, supplement, and expand the quantitative results of the trial, i.e. to examine individual perceptions of the intervention, including subjective changes and the extent to which elements of the program were integrated into everyday life. Qualitative content analysis techniques utilizing the software MAXQDA were used.

RESULTS

Patients with ulcerative colitis in our sample often experienced multiple negative effects on different levels (physical, psychological, and social) and impaired quality of life because of their disease. They reported generally positively about the program itself, and emphasized perceived positive changes regarding their psychological and physical well-being. The interviews indicated a good implementation of elements learned during the intervention in everyday life.

CONCLUSIONS

Through participation in a comprehensive lifestyle modification program in the structure of a day clinic complementary to pharmacotherapy, patients with ulcerative colitis can reduce psychosocial stress and physical symptoms and thereby actively improve their well-being and general quality of life. This patient-centered, holistic approach was rated as useful in countering the complex disease manifestation as well as meeting the individual needs of the patients regarding their disease.
