Randomised clinical trial: yoga vs written self-care advice for ulcerative colitis

Yoga in Pediatric Gastroenterology

PURPOSE OF REVIEW

Pediatric use of yoga as an integrative medicine modality has increased in prevalence over the last several decades. In this article, we review the available evidence for yoga in pediatric gastrointestinal disorders.

RECENT FINDINGS

Evidence supports that in many pediatric disorders of gut brain interaction (DGBI), including irritable bowel syndrome, functional abdominal pain and functional dyspepsia, yoga decreases pain intensity and frequency and increases school attendance. Yoga has been shown to improve health-related quality of life and improve stress management as an effective adjunct to standard medical therapy in pediatric inflammatory bowel disease (IBD). Further studies are needed regarding optimal frequency, duration of practice and evaluation of the impact on IBD disease activity measures. Yoga may benefit pediatric gastroenterology patients with DGBIs and IBD through improving quality of life and reducing pain. Future yoga studies could investigate biomarkers and continued research will help integrate this modality into routine pediatric gastroenterology care.

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.

A prospective, controlled multisite trial of yoga in pediatric inflammatory bowel disease

AIM

To investigate whether a structured yoga program improves health-related quality of life (HRQOL) and self-efficacy in pediatric patients receiving care for inflammatory bowel disease (IBD).

METHODS

IBD patients who were 10-17 years old participated in a 12 week, in-person yoga intervention at two clinical sites. Outcomes were measured at time of consent (T0), start of yoga (T1), and completion of yoga (T2) and 3 months after yoga completion (T3) using the IMPACT-III, Pediatric Quality of Life Inventory (PedsQL), and General Self Efficacy (GSE) scales.

RESULTS

Seventy-eight patients were enrolled. Fifty-six patients completed nine or more classes. 73.2% had Crohn's disease and 26.8% ulcerative colitis or IBD-unclassified. A significant increase in IMPACT-III was seen from T1 to T3 (mean change of 5.22, SD = 14.33, p = 0.010), in the PedsQL (mean change = 2.3, SD = 10.24, p = 0.050), and GSE (mean change = 1, SD = 3.60, p = 0.046). 85.2% of patients reported yoga helped them to control stress. Long-term data was available for 47 subjects with 31.9% (n = 15) continuing to practice yoga one to 3 years after study completion.

CONCLUSION

This structured 12-week yoga program showed significant improvements in HRQOL and general self-efficacy, particularly 3 months after classes were concluded suggesting that yoga's benefits may persist. Yoga is a safe and effective adjunct to standard medical care to improve QOL and self-efficacy in youth with IBD.

Do interventions for mood improve inflammatory biomarkers in inflammatory bowel disease?: a systematic review and meta-analysis

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.

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.

The Impact of a Yoga-Based Mindfulness Intervention versus Psycho-Educational Session for Older Adults with Mild Cognitive Impairment: The Protocol of a Randomized Controlled Trial

BACKGROUND

There is a global agreement in the medical community that a significant proportion of dementia cases could be prevented or postponed. One of the factors behind this agreement comes from scientific evidence showing that mind-body interventions such as mindfulness and yoga for the elderly have been related to a range of positive outcomes, including improved cognition performance in seniors with mild cognitive impairment (MCI).

OBJECTIVE

This study aims to evaluate the effectiveness of a yoga-based mindfulness intervention (YBM) versus psychoeducational sessions for older adults with MCI attending Hospital Clinic Universidad de Chile in Santiago.

METHOD

Two-arm, individually randomized controlled trial (RCT) will be carried out at Clinical Hospital Universidad de Chile in Santiago. Older people over 60 years with any type of MCI using a score < 21 in the Montreal Cognitive Assessment (MoCA) test and a score of 0.05 in the Clinical Dementia Rating (CDR) Scale; and with preserved activities of daily living will be randomly assigned with an allocation ratio of 1:1 in either the yoga-based mindfulness intervention or the active control group based on the psycho-educational program. People who have performed yoga and/or mindfulness in the last 6 months or/and people with a psychiatric clinical diagnosis will be excluded from the study. Montreal Cognitive Assessment, the Lawton Instrumental Activities of Daily Living Scale (IADL), the Barthel Index (BI), the Pemberton happiness index, the Geriatric Anxiety Inventory (GAI) as well as the Geriatric Depression Scale (GDS-5) will be administered by blinded outcomes assessors before random assignment (Pre-test), the week following the last session of the intervention (post-test), and then after 3- and 6-months follow-up.

RESULTS

The YBM intervention protocol based on a video recording has been adapted and designed. This is the first RCT to examine the effects of a yoga-based mindfulness intervention in improving cognitive and physical functions and mental health outcomes for Chilean elderly diagnosed with MCI. It is expected to be implemented as an acceptable and effective non-pharmacological option for older people with MCI.

CONCLUSION

Providing evidence-based programs such as preventive therapy for Alzheimer's disease has relevant implications for public mental health services in Chile.

Lifestyle, behaviour, and environmental modification for the management of patients with inflammatory bowel diseases: an International Organization for Study of Inflammatory Bowel Diseases consensus

Environmental and lifestyle factors play an important role in the natural history of Crohn's disease and ulcerative colitis. A group of international experts from the International Organization for the Study of Inflammatory Bowel Diseases voted on a series of consensus statements to inform the management of inflammatory bowel disease (IBD). The recommendations include avoiding traditional cigarette smoking in patients with Crohn's disease or ulcerative colitis, screening for symptoms of depression, anxiety, and psychosocial stressors at diagnosis and during flares (with referral to mental health professionals when appropriate), and encouraging regular physical activity as tolerated. Patients using dietary approaches for treatment of their IBD should be encouraged to adopt diets that are best supported by evidence and involve monitoring for the objective resolution of inflammation. We recommend formal assessment for obesity and nutritional deficiencies, and patients should be encouraged to maintain a normal body-mass index. A shared decision-making approach to contraception should include the consideration of IBD-related factors, and risk factors for venous thromboembolism. Long-term or frequent use of high-dose non-steroidal anti-inflammatory drugs should be avoided. For primary prevention of disease in the offspring of patients with IBD, we recommend avoiding passive exposure to tobacco, using antibiotics judiciously, and considering breastfeeding when able.

Physical Activity in Patients With Inflammatory Bowel Disease: A Narrative Review

BACKGROUND

Despite advancement in the treatment of inflammatory bowel disease (IBD), induction and maintenance of remission remain challenging to achieve in many patients and a significant proportion of patients with IBD experience mental health conditions, including anxiety, depression, and fatigue, which impair their quality of life (QoL). We aim to describe the available evidence regarding the effects of physical activity (PA) on the onset of IBD, its disease course, and important patient-reported outcome measures (PROMs), such as QoL, fatigue, and mental health.

METHODS

A literature search was performed using electronic databases to identify original articles that assessed the effects of PA in patients with IBD using PROMs.

RESULTS

Prospective cohort and case-control studies demonstrate inverse relationships between PA and new-onset IBD in Crohn's disease but not in ulcerative colitis; however, they have small sample sizes and caution must be taken in considering associations versus causation. Small randomized controlled trials suggest promise for PA and beneficial outcomes, such as maintenance of clinical remission and improvement in QoL, fatigue, depression, and anxiety. However, these studies were small and underpowered, and limited by outcome measurements and durations of follow-up.

CONCLUSIONS

Physicians may consider discussing PA interventions with their patients on an individual basis, especially if they report impaired QoL, fatigue, depression, or anxiety, until disease-specific guidelines are available. Including PA as part of a primary prevention strategy in high-risk patients could be considered.

Yoga in Patients With Inflammatory Bowel Disease: A Narrative Review

Despite advancements in the treatment of inflammatory bowel disease (IBD), the global prevalence of IBD is increasing. Patients with IBD often experience a high psychosocial burden, worsening their IBD symptoms and increasing relapse, hospitalization rates, and healthcare costs, which impairs their quality of life (QoL). Evidence suggests that mind-body intervention in many chronic illnesses is effective in improving symptoms and QoL. Yoga is the most frequently used mind-body practice globally. Meta-analyses of randomized clinical trials and prospective studies have highlighted that yoga improves symptoms and QoL of patients with IBD; however, recommendations about indications for yoga as well as dose and frequency of yoga are lacking. The present narrative review aims to describe the available evidence regarding the effects of yoga on common patient-reported outcome measures in IBD, including depression, anxiety, stress, and QoL. Physicians can hence promote yoga interventions in their discussions with patients to help control these IBD-related outcome measures.

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.

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

OBJECTIVE

The present study presents long-term results of stress-related outcomes of a prospective RCT that evaluated effects of a ten-week comprehensive lifestyle-modification program (LSM) in patients with inactive ulcerative colitis (UC). In addition, exploratory results of a sub-study applying a laboratory stress protocol (Trier Social Stress Test; TSST) conducted within the RCT are reported.

METHODS

Ninety-seven patients with inactive UC were randomized to LSM (n = 47; 50.28 ± 11.90 years; 72.3% female) or self-care (n = 50; 45.54 ± 12.49 years; 70% female). Patients' perceived stress, anxiety, flourishing and depression were assessed at week 0, 12, 24 and 48. After the respective intervention, 16 female patients (LSM: n = 8; 44.6 ± 14.3 years; Self-care: n = 8; 49.25 ± 4.30 years) additionally underwent the TSST. State anxiety, blood pressure, pulse, complete blood counts, adrenocorticotropic hormone (ACTH), cortisol, adrenalin and noradrenalin were measured at baseline (-15 min), stress (+10 min), recovery1 (+20 min) and recovery2 (+55 min). Statistical significance was set at p < 0.05; for the exploratory sub-study using the TSST, p-values < 0.10 were considered significant.

RESULTS

Patients' perceived stress declined significantly after the LSM (p < 0.001) compared with control. This lasted until week 24 (p = 0.023) but did not persist until week 48 (p = 0.060). After 48 weeks, patients' flourishing was significantly increased compared with control (p = 0.006). In response to the TSST, significant group differences were evident for pulse (p = 0.015), adrenaline (p = 0.037) and anxiety (p = 0.066). After 55 min, group differences were found for ACTH (p = 0.067) and systolic blood pressure (p = 0.050).

CONCLUSIONS

LSM has a medium-term positive effect on perceived stress. First indications show that it is promising to investigate these effects further under laboratory conditions. It is also desirable to find out how the effects of LSM can be maintained in the long term.

Effects of yoga in inflammatory bowel diseases and on frequent IBD-associated extraintestinal symptoms like fatigue and depression

Quality of life (QoL) of persons with inflammatory bowel diseases (IBD) is often impaired by symptoms that do not primarily relate to intestinal inflammation. Among the most challenging extraintestinal symptoms are depression and fatigue, which are also frequent in other chronic diseases like multiple sclerosis, rheumatoid arthritis and cancer. Yoga as an ancient Indian tradition containing postures, breathing exercises and meditation may positively influence those symptoms. This review evaluates the current literature with regard to the effect of yoga-based interventions in persons with IBD and with regard to QoL, depression and fatigue in other somatic disorders. A systematic literature search yielded three trials examining the effects of yoga in patients with IBD and 37 trials addressing depressive syndromes or fatigue in somatic disorders. In summary, both in-person and video-based yoga classes are feasible, acceptable and safe as complementary treatment in patients with IBD and significantly improve anxiety and impaired quality of life. Current literature does not provide information on the effect of yoga on depression and fatigue in patients with IBD, but research from other somatic disorders or patients with depressive disorders implies the potential of yoga in this regard for persons with IBD. This should be specifically addressed in interventional trials with standardized yoga modules including patients with IBD suffering from fatigue, depression and/or impaired QoL.

Evaluation of an integrated yoga program in patients with inflammatory bowel disease: A pilot study

BACKGROUND

The effects of integrated yoga programs on mental health outcomes in inflammatory bowel disease (IBD) have not been well explored. To explore the acceptability, implementation and effectiveness of an integrated eight-week yoga program plus aromatherapy massage in patients with IBD.

METHODS

Nine participants with documented IBD were recruited from a gastroenterology clinic in Calgary, Alberta, Canada to participate in an integrated yoga program weekly for eight weeks with outcomes assessed at baseline and week 8. Primary outcomes were assessed using Theory of Planned Behaviour as a guiding theory to identify salient beliefs from qualitative analysis of a semi-structured interview, survey items measuring the strength of beliefs and a daily log was used to capture adherence and adverse events. Secondary outcomes were collected using validated survey tools examining anxiety, depression, stress, sleep quality, and physical and mental quality of life.

RESULTS

Attitude, subjective norm and perceived behavioral control beliefs pertinent to the yoga intervention and daily practice were identified. Participants reported feeling the intervention was very helpful; however, felt guilt about not completing daily practices which decreased confidence and intention to continue with the practice. An average of 55.6% of in-person sessions were attended and decreased over time. Participants practiced on average of 5.4 days per week. Depression and mental health scores improved at week 8 from baseline.

CONCLUSIONS

We were able to identify key salient beliefs of IBD patients in regard to an integrated yoga plus aromatherapy massage intervention. This intervention appears to be acceptable and further research should explore its potential to improve mental and physical health outcomes including IBD symptoms.

Effect of yoga and naturopathy on disease activity and symptom burdens in a patient with active ulcerative colitis: a case report

OBJECTIVES

Ulcerative colitis (UC) is a chronic idiopathic inflammatory disease that affects the large bowel. The objective of this study is to find the effect of yoga and naturopathy (YN) in a patient with active moderate pancolitis.

CASE PRESENTATION

An 18-year old unmarried female diagnosed with UC in 2017. Patient's symptoms began with abdominal pain, nausea, vomiting and diarrhea with/without blood stains more than seven times a day, daily. The symptoms reduced after taking regular conventional medication for a period of one-year. However, in February-2019, the patient visited our hospital with the same complaints and received 21-days of YN treatments. Results showed a better reduction in the abdominal pain, disease activity, stress and depression and a better improvement in hemoglobin levels, quality of sleep, and quality of life with no adverse effects.

CONCLUSIONS

YN could be considered as an alternative therapy in the management of UC. However, further studies are required to warrant this effect.

Subjective Psychophysical Experiences in the Course of Inflammatory Bowel Disease-A Comparative Analysis Based on the Polish Pediatric Crohn's and Colitis Cohort (POCOCO)

No gold standard is available to evaluate subjective psychophysical experiences in pediatric inflammatory bowel disease (IBD). We aimed to assess pain, anxiety, and limitations in social activities at diagnosis and the worst flare of the disease in relation to clinical expression, treatment and IBD severity. A total of 376 children completed the survey (Crohn’s disease (CD) n = 196; ulcerative colitis (UC) n = 180). The questionnaire included 12 questions regarding pain, anxiety, and social activity, all assessed at recruitment and retrospectively at diagnosis and worst flare using a numeric rating scale. Patients that had ever been treated with systemic glucocorticosteroids scored higher in pain (p < 0.001), anxiety (p = 0.015), and social activity domains (p < 0.016) at worst flare, and the answers correlated with the number of steroid courses (p < 0.0392). The perception of social activity limitations also correlated independently with the number of immunosuppressants (p < 0.0433) and biological agents (p < 0.0494). There was no difference in retrospective perception of pain, anxiety and social activity limitations between CD and UC patients at diagnosis and the worst flare. The level of limitations in social activity correlated with hospitalisations due to relapse, days spent in the hospital, number of relapses, and severe relapses with the strongest association of rho = 0.39 (p = 0.0004). Subjective and retrospective perception of pain, anxiety, and limitations in social activity differs depending on therapy, correlates with treatment modalities, and severity measures such as hospitalisations.

Non-pharmacological Interventions for Anxiety and Depression in Adults With Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis

Objectives: To assess the published randomized controlled trials (RCT) of non-pharmacological interventions systematically and to synthesize the evidence of these interventions for the management of anxiety and depression in adults with inflammatory bowel disease (IBD).

Background: Anxiety and depression are common symptoms in adults with IBD and can have many negative outcomes on their quality of life (QOL). Non-pharmacological interventions for anxiety and depression are important to improve the adaptive strategies of adults with IBD. Previously published reviews of non-pharmacological interventions to mitigate anxiety and depression in those with IBD have resulted in inconclusive evidence. This review is aimed to fill that gap.

Design: Systematic review and meta-analysis.

Method: Using a PRISMA diagram, English-language RCT published were searched using combined keywords of inflammatory bowel disease, Crohn's disease, ulcerative colitis, randomized controlled trial, anxiety, and depression. The Cochrane risk of bias tool is utilized to assess the methodological quality of each study. A meta-analysis of RCTs was conducted using Comprehensive Meta-Analysis (CMA) software.

Results: The final review included 10 studies. The overall risk of bias of the selected studies varied from low risk in three studies, some concerns in four of the studies, and high risk of bias in three of the studies. Interventions included cognitive-behavioral therapy, mindfulness-based therapy, breath–body- mind –workshop, guided imagery with relaxation, solution-focused therapy, yoga, and multicomponent interventions. The pooled evidence from all non-pharmacological interventions showed that these interventions significantly helped to reduce anxiety, depression, and disease specific quality of life (QOL) in adults with IBD compared to control groups. However, the effect sizes are small. The pooled standardized mean difference (SMD) was −0.28 (95% CI [−0.47, −0.09], p = 0.004) for anxiety, −0.22 (95% CI [−0.41, −0.03], p = 0.025) for depression and 0.20 (95% CI [0.004, 0.39], p = 0.046) for disease specific QOL.

Conclusion: The addressed non-pharmacological interventions were multifaceted and demonstrated positive effects on anxiety and depression, and QOL in those with IBD. Healthcare providers can facilitate a discussion with adults with IBD about the availability of these interventions to mitigate their anxiety and depression and to improve their QOL.

The Impact of Spirituality and Religiosity on Mental Health and Quality of Life of Patients with Active Crohn's Disease

We aim to investigate the association among religious/spiritual coping (RSC), quality of life (QOL), and mental health in patients with active Crohn's disease (CD). This cross-sectional study included 102 patients with active CD. Religious and spiritual beliefs were common among patients, being positive RSC higher than negative RSC. Negative coping was associated with mood disorders (depressive or anxiety symptoms) through the Hospital Anxiety and Depression Scale (β = 0.260, p < 0.01) but not with QOL (Inflammatory Bowel Disease Questionnaire) (β = - 0.105, p = NS) after adjustments. Positive coping and other religious/spiritual beliefs and behaviors were not associated with either QOL or mental health. This study suggests that a negative RSC is associated with worse mental health outcomes. This may detrimentally impact adaptations to deal with CD in the active phase, although patients generally tend to use more common positive strategies. These findings may increase the awareness of health professionals while dealing with spiritual beliefs in patients with CD.

Perceived stress mediates the effect of yoga on quality of life and disease activity in ulcerative colitis. Secondary analysis of a randomized controlled trial

OBJECTIVE

Yoga positively affects health-related quality of life and disease activity in ulcerative colitis. The underlying modes of action remain unclear. Within the present study we hypothesized that patients´ perceived stress mediates the effects of yoga on health-related quality of life and disease activity.

METHODS

This is a secondary analysis of a randomized controlled trial comparing the effects of yoga to written self-care advice in patients with inactive ulcerative colitis and impaired quality of life. Perceived stress was assessed using the Perceived Stress Questionnaire, health-related quality of life using the Inflammatory Bowel Disease Questionnaire and disease activity using the Clinical Activity Index. Outcomes were assessed at weeks 0, 12 and 24.

RESULTS

Seventy-seven patients participated. Thirty-nine patients attended the 12 supervised weekly yoga sessions (71.8% women; 45.0 ± 13.3 years) and 38 patients written self-care advice (78.9% women; 46.1 ± 10.4 years). Perceived stress correlated significantly with health-related quality of life and disease activity at week 24. Perceived stress at week 12 fully mediated the effects of yoga on health-related quality of life (B = 16.23; 95% Confidence interval [6.73; 28.40]) and disease activity (B = -0.28; 95% Confidence interval [-0.56; -0.06]) at week 24.

CONCLUSION

Our findings confirm the importance of perceived stress in reducing disease activity and increasing health-related quality of life in patients with ulcerative colitis and impaired quality of life. Practitioners should keep psychosocial risk in mind as a risk factor for disease exacerbation, and consider yoga as an adjunct intervention for highly stressed patients with ulcerative colitis.

Stress and the brain-gut axis in functional and chronic-inflammatory gastrointestinal diseases: A transdisciplinary challenge

The broad role of stress in the brain-gut axis is widely acknowledged, with implications for multiple prevalent health conditions that are characterized by chronic gastrointestinal symptoms. These include the functional gastrointestinal disorders (FGID), such as irritable bowel syndrome and functional dyspepsia, as well as inflammatory bowel diseases (IBD) like ulcerative colitis and Crohn's disease. Although the afferent and efferent pathways linking the gut and the brain are modulated by stress, the fields of neurogastroenterology and psychoneuroendocrinology (PNE)/ psychoneuroimmunology (PNI) remain only loosely connected. We aim to contribute to bringing these fields closer together by drawing attention to a fascinating, evolving research area, targeting an audience with a strong interest in the role of stress in health and disease. To this end, this review introduces the concept of the brain-gut axis and its major pathways, and provides a brief introduction to epidemiological and clinical aspects of FGIDs and IBD. From an interdisciplinary PNE/PNI perspective, we then detail current knowledge regarding the role of chronic and acute stress in the pathophysiology of FGID and IBD. We provide an overview of evidence regarding non-pharmacological treatment approaches that target central or peripheral stress mechanisms, and conclude with future directions, particularly those arising from recent advances in the neurosciences and discoveries surrounding the gut microbiota.

Structured physical activity interventions as a complementary therapy for patients with inflammatory bowel disease - a scoping review and practical implications

BACKGROUND

Patients with Inflammatory Bowel Disease (IBD) also suffer from a wide range of additional disorders, which may be caused by the disease, the side effect of the medication, or a lack of physical activity (PA). This results in reduced physical and psychological wellbeing. However, as known from other chronic diseases exercise could be utilized as supportive therapy for IBD patients. Main goals of this article are (a) collecting data of the effects structured physical activity interventions have on validated clinical parameters of IBD and health related symptoms, (b) developing activity recommendations for this clientele.

METHODS

A scoping review was conducted, searching for relevant articles published until May 2018, which investigated the effects of structured exercise interventions in IBD patients. The heterogeneity of the outcomes and the interventions did not support a quantitative synthesis thus, a qualitative discussion of the studies is provided.

RESULTS

After reviewing 353 records, 13 eligible articles were identified. Five studies investigated aerobic exercise, three studies resistance exercise, three studies mind-body therapies and two studies yoga. The quality of the studies is mixed, and the duration is rather short for exercise interventions. Only few studies assessed validated IBD activity markers or inflammatory biomarkers. Nevertheless, the patients showed an increase in fitness, bone mineral density (BMD), quality of life and a decrease of IBD induced stress and anxiety. No severe adversial events were reported.

CONCLUSION

Even though the evidence is limited the application of exercise interventions in IBD patients can be assumed to be safe and beneficial for the patients' overall-health, and IBD specific physical and psychosocial symptoms. But there is still a high demand for more thoroughly conducted studies, focussing on important clinical outcome parameters.

European Crohn's and Colitis Organisation Topical Review on Complementary Medicine and Psychotherapy in Inflammatory Bowel Disease

Patients with inflammatory bowel disease [IBD] increasingly use alternative and complementary therapies, for which appropriate evidence is often lacking. It is estimated that up to half of all patients with IBD use various forms of complementary and alternative medicine during some point in their disease course. Considering the frequent use of such therapies, it is crucial that physicians and patients are informed about their efficacy and safety in order to provide guidance and evidence-based advice. Additionally, increasing evidence suggests that some psychotherapies and mind-body interventions may be beneficial in the management of IBD, but their best use remains a matter of research. Herein, we provide a comprehensive review of some of the most commonly used complementary, alternative and psychotherapy interventions in IBD.

A systematic review and meta-analysis of mindfulness based interventions and yoga in inflammatory bowel disease

BACKGROUND

Mindfulness interventions are increasingly used as a part of integrated treatment in inflammatory bowel disease (IBD) but there are limited data and a lack of consensus regarding effectiveness.

OBJECTIVES

We explored the efficacy of mindfulness interventions compared to treatment as usual (TAU), or other psychotherapeutic interventions, in treating physical and psychosocial symptoms associated with IBD.

METHODS

We conducted a systematic review and meta-analysis of relevant randomized controlled trials (RCTs). We included a broad range of mindfulness interventions including mindfulness-based interventions and yoga, with no restrictions on date of publication, participants' age, language or publication type. We searched the following electronic databases: MEDLINE, EMBASE, PsycINFO, CINAHL and WHO ICTRP database. We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines in conducting the review.

RESULTS

We included eight studies in the meta-analysis. Mindfulness interventions showed a statistically significant effect on stress in both the short(SMD = -0.48; 95%CI:-0.97, 0.00; P = .05), and long term(SMD = -0.55; 95%CI:-0.78, -0.32; P < .00001), significant long term effects on depression (SMD = -0.36; 95%CI:-0.66, -0.07; P = .02) and quality of life (SMD = 0.38; 95%CI:0.08, 0.68; P = .01),and small but not statistically significant improvements in anxiety (SMD = -0.27; 95%CI:-0.65, 0.11; P = .16).Effects on physical outcomes were equivocal and not statistically significant.

CONCLUSIONS

Mindfulness interventions are effective in reducing stress and depression and improving quality of life and anxiety, but do not lead to significant improvements in the physical symptoms of IBD. Further research involving IBD-tailored interventions and more rigorously designed trials is warranted.

Stress Triggers Flare of Inflammatory Bowel Disease in Children and Adults

Inflammatory bowel disease (IBD) is an idiopathic inflammatory disease characterized by chronic and relapsing manifestations. It is noteworthy that the prevalence of IBD is gradually increasing in both children and adults. Currently, the pathogenesis of IBD remains to be completely elucidated. IBD is believed to occur through interactions among genetics, environmental factors, and the gut microbiota. However, the relapsing and remitting course of IBD underlines the importance of other modifiers, such as psychological stress. Growing evidence from clinical and experimental studies suggests that stress acts as a promoting or relapsing factor for IBD. Importantly, recent studies have reported an increasing incidence of anxiety or depression in both children and adults with IBD. In this article, we review the mechanisms by which stress affects IBD, such as via impaired intestinal barrier function, disturbance of the gut microbiota, intestinal dysmotility, and immune and neuroendocrine dysfunction. With regard to both children and adults, we provide recent evidence to describe how stress can affect IBD at various stages. Furthermore, we emphasize the importance of mental healing and discuss the value of approaches targeting stress in clinical management to develop enhanced strategies for the prevention and treatment of IBD.

Stress burden and neuroendocrine regulation of cytokine production in patients with ulcerative colitis in remission

Stress demonstrably contributes to disease course in patients with inflammatory bowel diseases but the underlying mechanisms remain elusive. Here, we investigated if neuroendocrine regulation of pro- and anti-inflammatory cytokine production by peripheral blood immune cells is altered in patients with ulcerative colitis in remission (UCR). Using a whole blood stimulation assay, we measured the sensitivity of lipopolysaccharide (LPS)-induced TNF-α and IL-10 production to the glucocorticoid receptor agonist dexamethasone (DEX), the β₂-adrenergic receptor agonist terbutaline (TERB), and the α7-nicotinic acetylcholine receptor agonist 3-[2,4-dimethoxy-benzylidene]-anabaseine (GTS-21) in UCR patients (N = 26) and in healthy controls (HC, N = 25). Additionally, we assessed anxiety and depression symptoms as well as chronic perceived stress and disease-specific quality of life. Results showed that UCR patients exhibited greater anxiety, depression and chronic stress levels than HC, and reduced disease-specific quality of life. Plasma concentrations of TNF-α, IL-8, C-reactive protein (CRP) and lipopolysaccharide binding protein (LBP) were significantly higher, while LPS-induced IL-10 production was substantially lower in UCR compared to HC. Independent of group, DEX and GTS-21 dose-dependently inhibited TNF-α and IL-10 production, whereas TERB inhibited TNF-α and upregulated IL-10 production. However, at higher TERB doses (i.e., stress levels), upregulation of IL-10 production was significantly diminished in UCR compared to HC. Together, these findings demonstrate that downregulation of pro-inflammatory cytokine production in peripheral blood immune cells through glucocorticoid, adrenergic, and cholinergic mechanisms is essentially normal in UC in clinical remission and as efficient as in healthy individuals. However, UCR patients exhibited signs of systemic low-grade inflammation and dysregulation of anti-inflammatory IL-10 production. Impaired adrenergic upregulation of IL-10 production during remission could be one mechanism how stress facilitates relapse and conversion to symptomatic disease in these patients.

Vagus Nerve as Modulator of the Brain-Gut Axis in Psychiatric and Inflammatory Disorders

The vagus nerve represents the main component of the parasympathetic nervous system, which oversees a vast array of crucial bodily functions, including control of mood, immune response, digestion, and heart rate. It establishes one of the connections between the brain and the gastrointestinal tract and sends information about the state of the inner organs to the brain via afferent fibers. In this review article, we discuss various functions of the vagus nerve which make it an attractive target in treating psychiatric and gastrointestinal disorders. There is preliminary evidence that vagus nerve stimulation is a promising add-on treatment for treatment-refractory depression, posttraumatic stress disorder, and inflammatory bowel disease. Treatments that target the vagus nerve increase the vagal tone and inhibit cytokine production. Both are important mechanism of resiliency. The stimulation of vagal afferent fibers in the gut influences monoaminergic brain systems in the brain stem that play crucial roles in major psychiatric conditions, such as mood and anxiety disorders. In line, there is preliminary evidence for gut bacteria to have beneficial effect on mood and anxiety, partly by affecting the activity of the vagus nerve. Since, the vagal tone is correlated with capacity to regulate stress responses and can be influenced by breathing, its increase through meditation and yoga likely contribute to resilience and the mitigation of mood and anxiety symptoms.

The Vagus Nerve in the Neuro-Immune Axis: Implications in the Pathology of the Gastrointestinal Tract

The vagus nerve (VN) is the longest nerve of the organism and a major component of the parasympathetic nervous system which constitutes the autonomic nervous system (ANS), with the sympathetic nervous system. There is classically an equilibrium between the sympathetic and parasympathetic nervous systems which is responsible for the maintenance of homeostasis. An imbalance of the ANS is observed in various pathologic conditions. The VN, a mixed nerve with 4/5 afferent and 1/5 efferent fibers, is a key component of the neuro-immune and brain-gut axes through a bidirectional communication between the brain and the gastrointestinal (GI) tract. A dual anti-inflammatory role of the VN is observed using either vagal afferents, targeting the hypothalamic–pituitary–adrenal axis, or vagal efferents, targeting the cholinergic anti-inflammatory pathway. The sympathetic nervous system and the VN act in synergy, through the splenic nerve, to inhibit the release of tumor necrosis factor-alpha (TNFα) by macrophages of the peripheral tissues and the spleen. Because of its anti-inflammatory effect, the VN is a therapeutic target in the treatment of chronic inflammatory disorders where TNFα is a key component. In this review, we will focus on the anti-inflammatory role of the VN in inflammatory bowel diseases (IBD). The anti-inflammatory properties of the VN could be targeted pharmacologically, with enteral nutrition, by VN stimulation (VNS), with complementary medicines or by physical exercise. VNS is one of the alternative treatments for drug resistant epilepsy and depression and one might think that VNS could be used as a non-drug therapy to treat inflammatory disorders of the GI tract, such as IBD, irritable bowel syndrome, and postoperative ileus, which are all characterized by a blunted autonomic balance with a decreased vagal tone.
