Hypnosis and irritable bowel syndrome: a review of efficacy and mechanism of action

How hypnotic suggestions work - A systematic review of prominent theories of hypnosis

In recent decades, hypnosis has increasingly moved into the mainstream of scientific inquiry. Hypnotic suggestions are frequently implemented in behavioral, neurocognitive, and clinical investigations and interventions. Despite abundant reports about the effectiveness of suggestions in altering behavior, perception, cognition, and agency, no consensus exists regarding the mechanisms driving these changes. This article reviews competing theoretical accounts that address the genesis of subjective, behavioral, and neurophysiological responses to hypnotic suggestions. We systematically analyze the broad landscape of hypnosis theories that best represent our estimation of the current status and future avenues of scientific thinking. We start with procedural descriptions of hypnosis, suggestions, and hypnotizability, followed by a comparative analysis of systematically selected theories. Considering that prominent theoretical perspectives emphasize different aspects of hypnosis, our review reveals that each perspective possesses salient strengths, limitations, and heuristic values. We highlight the necessity of revisiting extant theories and formulating novel evidence-based accounts of hypnosis.

Hypnotherapy for persons with Irritable Bowel Syndrome: A three-arm randomized controlled trial

The current study sought to (1) compare the efficacies of Ericksonian hypnotherapy, traditional hypnotherapy, and educational talk in treating irritable bowel syndrome (IBS), and to (2) evaluate the impacts of hypnotic susceptibility on participants' responses to hypnotherapy. The study adopted a three-arm randomized controlled trial design and achieved an effective sample size of 144. Self-reported psychological questionnaires were used to assess participants' IBS symptom severity, health-related quality of life, and coping patterns at baseline, immediately post-intervention, and 3 months after intervention. The evaluation focused primarily on IBS symptom severity and health-related quality of life, as well as on the illness coping patterns of symptom catastrophizing and symptoms-related social hypervigilance.The findings showed that significant improvements in IBS symptom severity occurred in all three types of study groups immediately after completion of the intervention (p < .05, η_ρ² = .20). However, only the traditional hypnotherapy groups and the Ericksonian hypnotherapy groups still had a notably significant decrease in symptoms 3 months after the intervention, whereas the educational talk groups had dropped back to pre-treatment symptom levels at the 3-month follow-up. The amplitude of change of symptom catastrophizing in the traditional hypnotherapy groups was stronger than that in the Ericksonian hypnotherapy groups after completion of the intervention, and the two types of hypnotherapy groups were significantly lower in symptom catastrophizing both immediately after the intervention and also 3 months post-intervention (p < .001, η_ρ² = .17). The other coping mechanism studied, symptoms-related social hypervigilance, showed a significant decline only in the Ericksonian hypnotherapy groups (ps < .001, η_ρ² = .45). Interestingly, in the traditional hypnotherapy groups, persons with higher hypnotic susceptibility showed significant improvement in symptom severity, health-related quality of life, and coping patterns following treatment. Notably, the effects from Ericksonian hypnotherapy for IBS diverged from the effects from traditional hypnotherapy. Finally, both Ericksonian hypnotherapy and traditional hypnotherapy appeared to have greater positive effects than educational talk did, but at different levels.

Practitioners' experiences of using Gut Directed Hypnosis for irritable bowel syndrome: Perceived impact upon client wellbeing: A qualitative study

Gut Directed Hypnosis (GDH) is a specialised form of hypnotherapy originally developed to reduce gastrointestinal (GI) symptoms in individuals with Irritable Bowel Syndrome (IBS). IBS is a condition characterised by symptoms including bloating, abdominal pain and diarrhoea and/or constipation as well as psychosocial symptoms such as depression and anxiety. Although the specific mechanism of action remains unclear, it is suggested that GDH works on the brain-gut axis to improve GI symptoms, psychological functioning and overall wellbeing. The present study aimed to expand upon the knowledge surrounding GDH by exploring practitioners' experiences of using GDH for IBS and their perceptions of how it impacts upon client wellbeing. Six practitioners trained in GDH participated in one hour semi-structured interviews. Thematic Analyses (TA) was used to analyse data. Three major themes emerged from data including: predisposing personality traits and vulnerabilities associated with IBS; GDH as evidence-based practice; and the future evolution of GDH. The findings from this study add to the growing body of literature exploring the use of GDH for IBS, by incorporating the perspective of practitioners working within this field.

How do people with refractory irritable bowel syndrome perceive hypnotherapy?: Qualitative study

OBJECTIVES

Hypnotherapy is recognised in the UK's National Institute for Health and Care Excellence (NICE) guidelines as a potential treatment for Irritable Bowel Syndrome (IBS). However, little is known about the views of people with IBS regarding hypnotherapy. This qualitative study aimed to identify perceptions of and barriers to hypnotherapy for IBS by people with the condition.

DESIGN

One-to-one semi-structured interviews using thematic analysis.

SETTING

Convenience sampling in the UK. Participants were recruited by poster advertising and online IBS support groups. Interviews were conducted at the interviewees' preferred location or via video calling.

PARTICIPANTS

17 people (15 female, 2 male) who self-identified as having refractory IBS according to a provided definition.

RESULTS

Four hypnotherapy related themes arose from the data: conceptualisation of hypnotherapy, hypnotherapy for IBS, barriers to hypnotherapy for IBS, ideal format of hypnotherapy for IBS. Participants saw hypnosis as an altered state in which change was possible, but many had not considered it for IBS. They were broadly open to hypnotherapy for IBS, but a variety of potential barriers were apparent, including cost and therapist validity. Group hypnotherapy was less acceptable than one-to-one treatment. Hypnotherapy via video call was seen as convenient, but there were concerns about its effectiveness.

CONCLUSION

People with IBS may be put off hypnotherapy by a lack of understanding of how it works for their condition and lack of awareness of it as a therapeutic option. Uptake may be improved through effective promotion of the approach which addresses its mechanisms of effect.

A Randomized Trial of a Group-Based Integrative Medicine Approach Compared to Waitlist Control on Irritable Bowel Syndrome Symptoms in Adults

INTRODUCTION

Irritable bowel syndrome (IBS) is a chronic debilitating functional gastrointestinal disorder that affects a large proportion of the general population. Dietary and mind-body approaches have shown some effectiveness in reducing IBS symptoms.

OBJECTIVES

The purpose of this project was to test the feasibility of a low cost, group-oriented integrative medicine approach to IBS, and to explore whether such an approach improves participant outcomes.

METHODS

This was a randomized-controlled trial involving a 4-week group-oriented treatment intervention combining dietary intervention and mind-body therapies followed by 8-weeks of telephonic health coaching. Differences between the intervention and control groups on IBS-specific measures were examined at baseline, 4, 8, and 12-week.

RESULTS

Fifty-two participants completed the study, 30 in the control group and 22 in the intervention group. On the IBS Symptom Severity Score, at 4 weeks the intervention group showed statistically significant improvement compared to the control group (p < .02), which was sustained at the 8 and 12-week data points as well, with the proportion of the intervention group experiencing moderate to severe symptoms decreasing from 81.3% at baseline to 45% at week 4 and 54.5% at week 12. A statistically significant improvement was also seen on the CES-D measure of depression between baseline and week 12 in the intervention group compared to controls. On the IBS Quality of Life measure we did not observe a statistically significant difference between the groups.

CONCLUSIONS

This low-cost, group-oriented intervention approach offers a strategy to address the challenge of access to this type of integrative approach for patients of low socioeconomic status or limited means.

Neurobiology of early life stress and visceral pain: translational relevance from animal models to patient care

BACKGROUND

Epidemiological studies show that females are twice as likely to receive a diagnosis of irritable bowel syndrome (IBS) than their male counterparts. Despite evidence pointing to a role for sex hormones in the onset or exacerbation of IBS symptoms, the mechanism by which ovarian hormones may predispose women to develop IBS remains largely undefined. On the other hand, there is a growing body of research showing a correlation between reports of early life stress (ELS) and the diagnosis of IBS. Current treatments available for IBS patients target symptom relief including abdominal pain and alterations in bowel habits, but are not directed to the etiology of the disease.

PURPOSE

To better understand the mechanisms by which sex hormones and ELS contribute to IBS, animal models have been developed to mirror complex human experiences allowing for longitudinal studies that investigate the lifelong consequences of ELS. These preclinical models have been successful in recapitulating ELS-induced visceral pain. Moreover, in female rats the influence of cycling hormones on visceral hypersensitivity resembles that seen in women with IBS. Such studies suggest that rodent models of ELS may serve as pivotal tools in determining (i) the etiology of IBS, (ii) novel future treatments for IBS, and (iii) improving individualized patient care. The current review aims to shed light on the progress and the challenges observed by clinicians within the field of gastroenterology and the preclinical science aimed at addressing those challenges in an effort to understand and more efficiently treat functional gastrointestinal disorders (FGIDs) in both children and adults.

On the Origin of Interoception

Over the course of a century, the meaning of interoception has changed from the restrictive to the inclusive. In its inclusive sense, it bears relevance to every individual via its link to emotion, decision making, time-perception, health, pain, and various other areas of life. While the label for the perception of the body state changes over time, the need for an overarching concept remains. Many aspects can make any particular interoceptive sensation unique and distinct from any other interoceptive sensation. This can range from the sense of agency, to the physical cause of a sensation, the ontogenetic origin, the efferent innervation, and afferent pathways of the tissue involved amongst others. In its overarching meaning, interoception primarily is a product of the central nervous system, a construct based on an integration of various sources, not per se including afferent information. This paper proposes a definition of interoception as based on subjective experience, and pleas for the use of specific vocabulary in addressing the many aspects that contribute to it.

Snapshot of an integrated psychosocial gastroenterology service

AIM: To characterize the patients utilizing a gastroenterology behavioral medicine service and examine the effect of treatment on health care utilization.

METHODS: Patients were referred by their gastroenterologists for psychological treatment during a 15 mo period. Patients seen for an intake with a psychologist completed the Brief Symptom Inventory (BSI) and a checklist of psychosocial concerns. A subset of patients with functional bowel disorders also completed a disease specific quality of life measure. Chart review was conducted to obtain information on type and frequency of sessions with the psychologist, the number of outpatient gastroenterology visits, and number of gastroenterology-related medical procedures during the 6 mo following psychological intake.

RESULTS: Of 259 patients referred for treatment, 118 (46%) completed an intake with a psychologist. Diagnoses included: irritable bowel syndrome (42%), functional dyspepsia (20%), inflammatory bowel diseases (20%), esophageal symptoms (10%), and “other” (8%). Demographic variables and disease type did not differentiate between those who did and did not schedule an intake. Mean t-scores for the BSI global score index and the depression, anxiety, and somatization subscales fell below the cutoff for clinical significance (t = 63). Treatments were predominantly gut-directed hypnosis (48%) and cognitive behavioral therapy (44%). Average length of treatment was 4 sessions. Among functional gastrointestinal (GI) patients, those patients who initiated treatment received significantly fewer GI-related medical procedures during the 6 mo following the referral than patients who did not schedule an intake [t (197) = 2.69, P < 0.01].

CONCLUSION: Patients are receptive to psychological interventions for GI conditions and there is preliminary evidence that treatment can decrease health-care utilization among patients with functional GI conditions.

Mechanisms of hypnosis: toward the development of a biopsychosocial model

Evidence supports the efficacy of hypnotic treatments, but there remain many unresolved questions regarding how hypnosis produces its beneficial effects. Most theoretical models focus more or less on biological, psychological, and social factors. This scoping review summarizes the empirical findings regarding the associations between specific factors in each of these domains and response to hypnosis. The findings indicate that (a) no single factor appears primary, (b) different factors may contribute more or less to outcomes in different subsets of individuals or for different conditions, and (c) comprehensive models of hypnosis that incorporate factors from all 3 domains may ultimately prove to be more useful than more restrictive models that focus on just 1 or a very few factors.

Psychologic treatment of patients with psychogenic nonepileptic seizures

Psychogenic nonepileptic seizures are relatively common, often disabling and costly to patients and society. Most authorities consider psychologic treatment as the therapeutic intervention of choice. This review is intended primarily for psychologists and therapists who treat patients with psychogenic nonepileptic seizures, and for neurologists who make the diagnosis and wish to find out more about psychologic treatment options. The first section describes the nature and etiology of psychogenic nonepileptic seizures. General questions regarding the psychologic treatment of patients with psychogenic nonepileptic seizures are addressed, before discussing specific therapeutic approaches. The final part summarizes the authors' views on optimal treatment and the direction of future research.

Sensitivity and specificity of hypnosis effects on gastric myoelectrical activity

OBJECTIVES

The effects of hypnosis on physiological (gastrointestinal) functions are incompletely understood, and it is unknown whether they are hypnosis-specific and gut-specific, or simply unspecific effects of relaxation.

DESIGN

Sixty-two healthy female volunteers were randomly assigned to either a single session of hypnotic suggestion of ingesting an appetizing meal and an unappetizing meal, or to relax and concentrate on having an appetizing or unappetizing meal, while the electrogastrogram (EGG) was recorded. At the end of the session, participants drank water until they felt full, in order to detect EGG-signal changes after ingestion of a true gastric load. During both conditions participants reported their subjective well-being, hunger and disgust at several time points.

RESULTS

Imagining eating food induced subjective feelings of hunger and disgust as well as changes in the EGG similar to, but more pronounced than those seen with a real gastric water load during both hypnosis and relaxation conditions. These effects were more pronounced when imagining an appetizing meal than with an unappetizing meal. There was no significant difference between the hypnosis and relaxation conditions.

CONCLUSION

Imagination with and without hypnosis exhibits similar changes in subjective and objective measures in response to imagining an appetizing and an unappetizing food, indicating high sensitivity but low specificity.

The effect of Korean hand acupuncture on young, single Korean students with irritable bowel syndrome

The purpose of this study was to test the effectiveness of Korean hand acupuncture (KHA) on bowel symptoms, stress, mental health, and heart rate variability in women with irritable bowel syndrome. From a total sample of 42 women with irritable bowel syndrome diagnosed with Rome III, 21 were randomly selected to be given KHA, whereas 21 were given sham KHA. The KHA group received KHA on 16 spots related to bowel symptoms, whereas the sham KHA group received treatment to areas unrelated to bowel symptoms. KHA needles were applied for 25 minutes, twice a week, for 4 weeks. After the treatment, bowel symptoms were measured using a Bowel Symptom Severity Scale, stress using a global assessment of recent health, mental health using the Symptom Checklist-90-Revised, and heart rate variability. SAS 9.1 (SAS Institute, Cary, NC) was used to analyze the data, and a chi-square test, t test, and paired t test were used for analysis. The KHA group had a decrease in symptoms such as loose stool, bloating, abdominal discomfort, and abdominal pain compared with the sham KHA group (p < .05). However, there were no significant effects on stress, mental health, and heart rate variability. KHA was effective for bowel symptoms such as loose stool, bloating, abdominal discomfort, and abdominal pain, and it could be applied to patients with irritable bowel syndrome. There is a need for further research on the effectiveness of KHA in women with irritable bowel syndrome using more diverse physiological indexes.

Gut-directed hypnotherapy significantly augments clinical remission in quiescent ulcerative colitis

BACKGROUND

Psychotherapy is not routinely recommended for in ulcerative colitis (UC). Gut-directed hypnotherapy (HYP) has been linked to improved function in the gastrointestinal tract and may operate through immune-mediated pathways in chronic diseases.

AIMS

To determine the feasibility and acceptability of HYP and estimate the impact of HYP on clinical remission status over a 1-year period in patients with an historical flare rate of 1.3 times per year.

METHODS

A total of 54 patients were randomised at a single site to seven sessions of gut-directed HYP (n = 26) or attention control (CON; n = 29) and followed for 1 year. The primary outcome was the proportion of participants in each condition that had remained clinically asymptomatic (clinical remission) through 52 weeks post treatment.

RESULTS

One-way analysis of variance comparing HYP and CON subjects on number of days to clinical relapse favoured the HYP condition [F = 4.8 (1, 48), P = 0.03] by 78 days. Chi-squared analysis comparing the groups on proportion maintaining remission at 1 year was also significant [χ²(1) = 3.9, P = 0.04], with 68% of HYP and 40% of CON patients maintaining remission for 1 year. There were no significant differences between groups over time in quality of life, medication adherence, perceived stress or psychological factors.

CONCLUSION

This is the first prospective study that has demonstrated a significant effect of a psychological intervention on prolonging clinical remission in patients with quiescent ulcerative colitis (Clinical Trial # NCT00798642).

Which psychological factors exacerbate irritable bowel syndrome? Development of a comprehensive model

OBJECTIVE

There is evidence that psychological factors affect the onset, severity and duration of irritable bowel syndrome (IBS). However, it is not clear which psychological factors are the most important and how they interact. The aims of the current study are to identify the most important psychological factors predicting IBS symptom severity and to investigate how these psychological variables are related to each other.

METHODS

Study participants were 286 IBS patients who completed a battery of psychological questionnaires including neuroticism, abuse history, life events, anxiety, somatization and catastrophizing. IBS severity measured by the IBS Severity Scale was the dependent variable. Path analysis was performed to determine the associations among the psychological variables, and IBS severity.

RESULTS

Although the hypothesized model showed adequate fit, post hoc model modifications were performed to increase prediction. The final model was significant (Chi(2)=2.2; p=0.82; RMSEA<.05) predicting 36% of variance in IBS severity. Catastrophizing (standardized coefficient (β)=0.33; p<.001) and somatization (β=0.20; p<.001) were the only two psychological variables directly associated with IBS severity. Anxiety had an indirect effect on IBS symptoms through catastrophizing (β=0.80; p<.001); as well as somatization (β=0.37; p<.001). Anxiety, in turn, was predicted by neuroticism (β=0.66; p<.001) and stressful life events (β=0.31; p<.001).

CONCLUSION

While cause-and-effect cannot be determined from these cross-sectional data, the outcomes suggest that the most fruitful approach to curb negative effects of psychological factors on IBS is to reduce catastrophizing and somatization.

Psychopharmacological treatment and psychological interventions in irritable bowel syndrome

Irritable bowel syndrome (IBS) accounts for 25% of gastroenterology output practice, making it one of the most common disorders in this practice. Psychological and social factors may affect the development of this chronic disorder. Furthermore, psychiatric symptoms and psychiatric diseases are highly prevalent in this condition, but the approach to treating these is not always straightforward. As emphasized in the biopsychosocial model of IBS, with regard to the modulatory role of stress-related brain-gut interactions and association of the disease with psychological factors and emotional state, it proves useful to encourage psychopharmacological treatments and psychosocial therapies, both aiming at reducing stress perception. The aim of this paper is to analyze the effectiveness of psychopharmacological treatment and psychological interventions on irritable bowel syndrome.

Cognitive hypnotherapy: a new vision and strategy for research and practice

This article describes cognitive hypnotherapy (CH), a visionary model of adjunctive hypnotherapy that advances the role of clinical hypnosis to a recognized integrative model of psychotherapy. As hypnosis lacks a coherent theory of psychotherapy and behavior change, hypnotherapy has embodied a mixed bag of techniques and thus hindered from transfiguring into a mainstream school of psychotherapy. One way of promoting the therapeutic standing of hypnotherapy as an adjunctive therapy is to systematically integrate it with a well-established psychotherapy. By blending hypnotherapy with cognitive behavior therapy, CH offers a unified version of clinical practice that fits the assimilative model of integrated psychotherapy, which represents the best integrative psychotherapy approach for merging both theory and empirical findings.

Human microbiome in health and disease

Mammals are complex assemblages of mammalian and bacterial cells organized into functional organs, tissues, and cellular communities. Human biology can no longer concern itself only with human cells: Microbiomes at different body sites and functional metagenomics must be considered part of systems biology. The emergence of metagenomics has resulted in the generation of vast data sets of microbial genes and pathways present in different body habitats. The profound differences between microbiomes in various body sites reveal how metagenomes contribute to tissue and organ function. As next-generation DNA-sequencing methods provide whole-metagenome data in addition to gene-expression profiling, metaproteomics, and metabonomics, differences in microbial composition and function are being linked to health and disease states in different organs and tissues. Global parameters of microbial communities may provide valuable information regarding human health status and disease predisposition. More detailed knowledge of the human microbiome will yield next-generation diagnostics and therapeutics for various acute, chronic, localized, and systemic human diseases.

A Randomised, Cross-Over, Placebo-Controlled Study of Aloe vera in Patients with Irritable Bowel Syndrome: Effects on Patient Quality of Life

Background. Irritable bowel syndrome (IBS) is a chronic, difficult to treat condition. The efficacy of Aloe vera in treating IBS symptoms is not yet proven. The purpose of this study was to determine if Aloe vera is effective in improving quality of life. Methods. A multicentre, randomised, double-blind, cross-over placebo controlled study design. Patients were randomised to Aloe vera, wash-out, placebo or placebo, washout, Aloe vera. Each preparation (60 mL) was taken orally twice a day. Patient quality of life was measured using the Gastrointestinal Symptoms Rating Score, Irritable Bowel Syndrome Quality of Life, EuroQol and the Short-Form-12 at baseline and treatment periods 1 and 2. Results. A total of 110 patients were randomised, but only 47 completed all questionnaires and both study arms. Statistical analysis showed no difference between the placebo and Aloe vera treatment in quality of life. Discussion. This study was unable to show that Aloe vera was superior to placebo in improving quality of life. Drop outs and other confounding factors may have impacted on the power of the study to detect a clinically important difference. Conclusion. This study failed to find Aloe vera superior to placebo in improving quality of life proven Irritable Bowel Syndrome patients.

Integrative medicine and gastrointestinal disease

Common disorders of the gastrointestinal (GI) tract account for about 50 million visits per year to physicians trained in traditional allopathic or osteopathic medicine. Sometimes patients turn to more alternative treatments because standard medical therapy is either not producing the most desired result or may have side effects, or patients may see complementary or alternative therapies as more natural. In the United States, the overall expenditure for complementary and alternative medicine (CAM) is in the tens of billions of dollars per year. Because physicians need to be aware of the latest evidence for different complementary and alternative therapies used for gastrointestinal disorders, this article focuses on the most common and most studied CAM therapies for selected common gastrointestinal disorders.

Treatment of psychological co-morbidities in common gastrointestinal and hepatologic disorders

Anxiety and depressive disorders frequently coexist with gastrointestinal and hepatologic conditions. Despite their high prevalence, approach to treating these co-morbidities is not always straightforward. This paper aims to review the current literature into etiology of psychological co-morbidities and their treatment in three conditions commonly encountered at gastroenterology outpatient clinics, namely inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) and chronic hepatitis C (HepC). The paper demonstrates that although psychotherapy (and cognitive-behavioural therapy in particular) has been established as an effective treatment in IBS, more studies are needed in HepC and IBD. Antidepressants have been recognized as an effective treatment for psychological and somatic symptoms in IBS and for depression in HepC, but good quality studies in IBD are lacking despite the promising preliminary findings from animal models and case studies. Further studies in this area are needed.

Hypnosis and upper digestive function and disease

Hypnosis is a therapeutic technique that primarily involves attentive receptive concentration. Even though a small number of health professionals are trained in hypnosis and lingering myths and misconceptions associated with this method have hampered its widespread use to treat medical conditions, hypnotherapy has gained relevance as an effective treatment for irritable bowel syndrome not responsive to standard care. More recently, a few studies have addressed the potential influence of hypnosis on upper digestive function and disease. This paper reviews the efficacy of hypnosis in the modulation of upper digestive motor and secretory function. The present evidence of the effectiveness of hypnotherapy as a treatment for functional and organic diseases of the upper bowel is also summarized, coupled with a discussion of potential mechanisms of its therapeutic action.

Behavioral and complementary approaches for the treatment of irritable bowel syndrome

Irritable bowel syndrome (IBS) is one of the most common conditions seen in primary care settings. Despite this, there is no consensus as to the pathogenesis of this disorder or a consistently effective therapeutic regimen for many patients. This has encouraged the use of various alternative therapies from behavioral or complementary medicine. This review will address the evidence for alternative therapies, including the following: cognitive behavior therapy, hypnosis, elimination diets based on food antibody testing, nutrition supplements (such as fiber, probiotics, and prebiotics), and, finally, peppermint, l-glutamine, zinc, and cromolyn sodium. The review also explores the evidence for and the therapeutic ramifications of the hypothesis that increased intestinal permeability underlies the symptoms of IBS in many patients, and how a therapeutic plan that addresses nutrition, elimination diets, and nutrition supplements may be useful in restoring the integrity of the gut immune barrier.

Complementary and alternative medicine use and cost in functional bowel disorders: a six month prospective study in a large HMO

BACKGROUND

Functional Bowel Disorders (FBD) are chronic disorders that are difficult to treat and manage. Many patients and doctors are dissatisfied with the level of improvement in symptoms that can be achieved with standard medical care which may lead them to seek alternatives for care. There are currently no data on the types of Complementary and Alternative Medicine (CAM) used for FBDs other than Irritable Bowel Syndrome (IBS), or on the economic costs of CAM treatments. The aim of this study is to determine prevalence, types and costs of CAM in IBS, functional diarrhea, functional constipation, and functional abdominal pain.

METHODS

1012 Patients with FBD were recruited through a health care maintenance organization and followed for 6 months. Questionnaires were used to ascertain: Utilization and expenditures on CAM, symptom severity (IBS-SS), quality of life (IBS-QoL), psychological distress (BSI) and perceived treatment effectiveness. Costs for conventional medical care were extracted from administrative claims.

RESULTS

CAM was used by 35% of patients, at a median yearly cost of $200. The most common CAM types were ginger, massage therapy and yoga. CAM use was associated with female gender, higher education, and anxiety. Satisfaction with physician care and perceived effectiveness of prescription medication were not associated with CAM use. Physician referral to a CAM provider was uncommon but the majority of patients receiving this recommendation followed their physician's advice.

CONCLUSION

CAM is used by one-third of FBD patients. CAM use does not seem to be driven by dissatisfaction with conventional care. Physicians should discuss CAM use and effectiveness with their patients and refer patients if appropriate.

50 years of hypnosis in medicine and clinical health psychology: a synthesis of cultural crosscurrents

In 2008, the 50th anniversary of ASCH, hypnosis is used increasingly for healthcare applications in hospitals, clinics, and psychotherapy practice. A substantial body of research demonstrates the efficacy of hypnosis as part of the integrative treatment of many conditions that traditional medicine has found difficult to treat (e.g., Pinnell & Covino, 2000; Elkins, Jensen, & Patterson, 2007). The practice of hypnosis in healthcare has been altered and centrally influenced by the rapid growth of technological medicine in the 1950's, the AIDS epidemic and development of psychoneuroimmunology, revolutionary developments in genetics and neuroimaging technology, and the progression from alternative to integrative medicine. We have come to develop more detailed expectations about the beneficial effects of hypnotic interventions for health problems. We have also come to know that in these populations hypnosis can lead not only to reduced anxiety but also specifically altered physiological parameters.

[Pain and consciousness. Articles from the summer workshop held by the German Interdisciplinary Collaboration for Pain Therapy (DIVS) in 2005]

Six articles are presented which illustrate the activities at the summer workshop "Pain and awareness" held 27-28 May 2005 in Marienfeld by the German Interdisciplinary Collaboration for Pain Therapy (DIVS). One article on pain constructs in the mind explains the advantages of functional imaging methods: these enable characterization of partial aspects of pain processing in the brain and the mechanisms that lead to chronic states of pain syndromes. A further overview explains the influence of different drugs on pain perception and various conscious states. How back pain patients experience their illness was analyzed in a study using an explanatory model interview: somatic aspects were dominant, but in three-fourths of the patients psychological illness attributions also played a role. A summary from the perspective of religious history and theology explores how pain is interpreted and accepted in various religious communities. Another article addresses hypnosis as a complementary technique to anesthesia procedures in surgical medicine, for treating chronic pain and experimental acute pain. The last contribution deals with how people in different cultures experience pain: ethnocentric bias can lead to difficulties in communication and misjudgments when treating foreign-born patients. All in all the workshop highlighted important formative factors in pain processing in a condensed form and offered stimulating perspectives for this area of pain research and future treatment options.

An exploration of the utility of hypnosis in pain management among rural pain patients

Objective:Hypnosis is an adjunctive, noninvasive treatment with few side effects that can be useful in the management of chronic pain. However, it has fallen into disfavor in recent years and is often perceived by physicians as simple charlatanism. We evaluated the efficacy of this treatment as used clinically in a large, mostly rural, pain management center.

Methods:We conducted a chart review of 300 pain patients from the Pain Treatment Center of the Bluegrass who had undergone hypnosis for their pain concerns. A chart audit tool was developed consisting of basic demographics, pre- and posthypnosis pain ratings, a rating of relaxation achieved posthypnosis, and scores on the Beck Depression Inventory, Perceived Disability Scale, and the Pain Anxiety Symptom Scale.

Results:The sample consisted of 79 men (26.3%) and 221 women (73.7%) with a mean age of 46.3 years (SD= 9.9, range = 19–78). Pain levels recorded pre- and posthypnosis revealed significant improvement as a result of the intervention (mean difference = 2.5,t(1,298) = 25.9,p< .001). Patients reported an average of 49.8% improvement in relaxation level posthypnosis (SD= 24.2%) and had a mean score of 19.0 on the Beck Depression Inventory (SD= 9.9), indicating moderate levels of depression. Also, patients saw themselves as severely disabled regarding their ability to engage in physical (8.3/10) or job-related (7.7/10) activities. Attempts to identify predictors of hypnosis success were not fruitful with one exception. “Poor” responders to hypnosis reported greater levels of perceived dysfunction in their sexual functioning compared to the “good” responders,F(1,187) = 7.2,p< .01.

Significance of results:Hypnosis appears to be a viable adjunct for pain management patients, including those from rural and relatively disadvantaged backgrounds. Prospective trials are needed to examine the utility of this modality in end-of-life and palliative care patients.

Controversies surrounding the comorbidity of depression and anxiety in inflammatory bowel disease patients: a literature review

Psychological disorders are highly prevalent in patients with inflammatory bowel disease (IBD). Anxiety and depression are known to independently affect quality of life and may additionally impair quality of life in IBD over and above the IBD itself. Some researchers have further proposed that anxiety and depression may influence the clinical course of IBD. However, despite the potential for anxiety and depression to play an important role in the clinical picture of IBD, there is little prospective well-controlled research in this area. Probably because of this lack of clear data, researchers dispute the actual role of these psychological disorders in IBD, with a number of conflicting opinions expressed. This article reports on a review of the literature in this field. Herein we discuss the five main areas of controversy regarding IBD and the specific psychological comorbidities of depression and anxiety: 1) the relative rate of cooccurrence of these psychological disorders with IBD; 2) the cooccurrence of these psychological disorders with particular phase of IBD; 3) the cooccurrence of these psychological disorders with the specific type of IBD; 4) the rate of these psychological comorbidities compared both to healthy subjects and to other disease states; and 5) the timing of onset of psychological comorbidity with respect to onset of IBD. Methodological weaknesses of the reviewed studies make it impossible to resolve these controversies. However, the results clearly show that anxiety/depression and IBD frequently interact. Given the long-term illness burden patients with IBD face, further prospective, appropriately controlled studies are needed to adequately answer the question of the precise interplay between anxiety/depression and IBD.

[Psychosomatic aspects of bowel diseases]

Functional gastrointestinal disorders (FGID) and inflammatory bowel diseases (IBD) are the most frequently studied bowel disorders in the context of a bio psycho-social model. FGID are associated with significant work absenteeism, impaired quality of life, and increased medical costs. Many patients also suffer from psychosocial problems. Most of the research in FGID to date has focused on the irritable bowel syndrome. Randomised controlled studies have shown that psychotherapy is superior to conventional medical therapy. The gut-focussed hypnotherapy seems to be very successful. For IBD it is increasingly recognized that the psycho-neuro-endocrine network can modulate inflammation and pain perception and that psychosocial factors are related to exacerbation of and coping with IBD. The psychosocial consequences of the illness become more significant with increasing severity of the disease. Therefore integrated psychosomatic care should be provided, the patient's psychosocial status and the demand for additional psychological care should be assessed and offered, if indicated.

Systematic review: the effectiveness of hypnotherapy in the management of irritable bowel syndrome

AIM

To systematically review the literature evaluating hypnotherapy in the management of irritable bowel syndrome (IBS).

METHODS

Electronic databases were searched (Cochrane Library, Medline, CINAHL, AMED, Embase, PsycINFO, CISCOM, TRIP and the Social Science Citation index), bibliographic references scanned and main authors contacted. No restrictions were placed on language or publication year. Eligible studies involved adults with IBS using single-component hypnotherapy. All studies, except single case or expert opinion, were sought and all patient-related outcomes eligible.

RESULTS

Out of 299 unique references identified, 20 studies (18 trials of which four were randomized, two controlled and 12 uncontrolled) and two case series were eligible. These tended to demonstrate hypnotherapy as being effective in the management of IBS. Numbers of patients included were small. Only one trial scored more than four out of eight on internal validity.

CONCLUSION

The published evidence suggests that hypnotherapy is effective in the management of IBS. Over half of the trials (10 of 18) indicated a significant benefit. A randomized placebo-controlled trial of high internal validity is necessary to establish the effectiveness of hypnotherapy in the management of IBS. Until such a trial is undertaken, this form of treatment should be restricted to specialist centres caring for the more severe forms of the disorder.

Systematic review: Complementary and alternative medicine in the irritable bowel syndrome

BACKGROUND

Complementary and alternative medical therapies and practices are widely employed in the treatment of the irritable bowel syndrome.

AIM

To review the usage of complementary and alternative medicine in the irritable bowel syndrome, and to assess critically the basis and evidence for its use.

METHODS

A systematic review of complementary and alternative medical therapies and practices in the irritable bowel syndrome was performed based on literature obtained through a Medline search.

RESULTS

A wide variety of complementary and alternative medical practices and therapies are commonly employed by irritable bowel syndrome patients both in conjunction with and in lieu of conventional therapies. As many of these therapies have not been subjected to controlled clinical trials, some, at least, of their efficacy may reflect the high-placebo response rate that is characteristic of irritable bowel syndrome. Of those that have been subjected to clinical trials most have involved small poor quality studies. There is, however, evidence to support efficacy for hypnotherapy, some forms of herbal therapy and certain probiotics in irritable bowel syndrome.

CONCLUSIONS

Doctors caring for irritable bowel syndrome patients need to recognize the near ubiquity of complementary and alternative medical use among this population and the basis for its use. All complementary and alternative medicine is not the same and some, such as hypnotherapy, forms of herbal therapy, specific diets and probiotics, may well have efficacy in irritable bowel syndrome. Above all, we need more science and more controlled studies; the absence of truly randomized placebo-controlled trials for many of these therapies has limited meaningful progress in this area.

Irritable bowel syndrome: diagnosis and management

Irritable bowel syndrome is often dismissed as just being a nuisance rather than anything more serious, but its symptoms can seriously diminish a patient's quality of life. When the disease is better understood and treatment is tailored to the individual patient, it can often be rewarding to manage

Review article: The history of hypnotherapy and its role in the irritable bowel syndrome

Hypnosis is a technique by which an individual can gain a degree of control over physiological as well as psychological function. This paper reviews the history of the phenomenon as well as the accumulating evidence that it is effective in relieving the symptoms of irritable bowel syndrome and improving the quality of life of sufferers. The physiological effects of hypnosis are also discussed coupled with an outline of how a hypnotherapy service might be provided.
