3-5% of patients taking the 5HT1D agonist sumatriptan for migraine have chest discomfort, suggesting a cardiac origin. We have investigated an alternative explanation of an oesophageal cause in 24 volunteers after the subcutaneous administration of a supratherapeutic dose of sumatriptan (16 mg) or placebo in a randomised, double-blind crossover study. Sumatriptan did not alter the electrocardiogram but increased the amplitude (p < 0.001) and duration (p < 0.001) of oesophageal contractions without affecting velocity of propagation. Clinically abnormal motility was also increased (p = 0.001), and was more common in the 5 subjects with chest pain after sumatriptan. The effect of sumatriptan on oesophageal function provides an alternative explanation for the chest symptoms. [ABSTRACT FROM AUTHOR]

There is an abundance of outcomes research for clinical hypnosis showing promising results. Nonetheless, hypnosis is still underutilized in clinical care. For a behavioral intervention to enter mainstream clinical care, efficacy needs to be demonstrated with exceptionally high quality of evidence, and its reporting needs to be complete and sufficiently clear to enable replication and clinical use. The present article provides best practice guidelines formulated by the Task Force for Establishing Efficacy Standards for Clinical Hypnosis for conducting and reporting clinical hypnosis research.The recommendations are presented in two tiers. Tier I recommendations include essential best practices, such as a call for the use of detailed research and intervention manuals, plans for and reporting of participant-education about hypnosis, the use of hypnotizability scales with good psychometric properties, and clear reporting of the hypnotizability measurement. Tier I also includes the sharing of intervention manuals, the reporting of the induction procedure, the labeling of the intervention for participants, and the definition of hypnosis used. Tier II includes preferred recommendations, calling for measurement of adherence to home practice, measurement of hypnotizability using scales with both subjective and behavioral measures of responsiveness, and the involvement of participants from the full hypnotizability spectrum. Tier II also includes the assessment of variables related to proposed mechanisms of action, the reporting of participants prior hypnosis experiences, and the relationship of expectancies and treatment outcomes.This list of recommendations will be useful for researchers, reviewers, and journal editors alike when conducting, reporting, or evaluating studies involving clinical hypnosis., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Gut-directed hypnotherapy is effective for patients with irritable bowel syndrome (IBS). Despite its considerable evidence base, gut-directed hypnotherapy is not widely available and remains a limited resource. This emphasises the need to select patients who are most likely to benefit., Aim: To determine whether baseline patient characteristics were predictive of response to gut-directed hypnotherapy in patients with IBS METHODS: We conducted a secondary analysis of outcomes of 448 patients with refractory Rome III IBS who participated in a randomised study confirming non-inferiority of 6 compared to 12 sessions of gut-directed hypnotherapy. We compared baseline patient characteristics, including age, sex, IBS subtype, quality of life and IBS-Symptom Severity Scale (IBS-SSS), non-colonic symptom score and Hospital Anxiety and Depression (HAD) score between responders and non-responders. We defined response as ≥50-point decrease in IBS-SSS or ≥30% reduction in pain severity scores., Results: Overall, 76.3% achieved ≥50-point decrease in IBS-SSS. Responders had a higher baseline non-colonic symptom score (p = 0.005). Those who achieved ≥30% improvement in abdominal pain scores (59.8%) had higher baseline IBS-SSS (p = 0.03), and lower baseline HAD-depression score (p = 0.012). Fifty-four patients (12%) dropped out of gut-directed hypnotherapy. Compared to completers, dropouts had higher baseline HAD-anxiety score (p = 0.034)., Conclusions: These data suggest that patients with a higher burden of gastrointestinal and extraintestinal symptoms are most likely to benefit from gut-specific behavioural intervention for refractory IBS. Clinical assessment of gastrointestinal, somatic and psychological symptom profiles may play a role in selecting patients for gut-directed hypnotherapy., (© 2023 The Authors.

Background: There are minimal epidemiological data comparing the burden of disorders of gut brain interaction (DGBI) in the UK with other countries. We compared the prevalence of DGBI in the UK with other countries that participated in the Rome Foundation Global Epidemiology Study (RFGES) online., Methods: Participants from 26 countries completed the RFGES survey online including the Rome IV diagnostic questionnaire and an in-depth supplemental questionnaire with questions about dietary habits. UK sociodemographic and prevalence data were compared with the other 25 countries pooled together., Key Results: The proportion of participants with at least one DGBI was lower in UK participants compared with in the other 25 countries (37.6% 95% CI 35.5%-39.7% vs. 41.2%; 95% CI 40.8%-41.6%, p = 0.001). The UK prevalence of 14 of 22 Rome IV DGBI, including irritable bowel syndrome (4.3%) and functional dyspepsia (6.8%), was similar to the other countries. Fecal incontinence, opioid-induced constipation, chronic nausea and vomiting, and cannabinoid hyperemesis (p < 0.05) were more prevalent in the UK. Cyclic vomiting, functional constipation, unspecified functional bowel disorder, and proctalgia fugax (p < 0.05) were more prevalent in the other 25 countries. Diet in the UK population consisted of higher consumption of meat and milk (p < 0.001), and lower consumption of rice, fruit, eggs, tofu, pasta, vegetables/legumes, and fish (p < 0.001)., Conclusions and Inferences: The prevalence and burden of DGBI is consistently high in the UK and in the rest of the world. Opioid prescribing, cultural, dietary, and lifestyle factors may contribute to differences in the prevalence of some DGBI between the UK and other countries., (© 2023 The Authors.

An online survey of 691 clinicians who use hypnosis was conducted in 31 countries to gain a broad real-world picture of current practices, views, and experiences in clinical hypnosis. Among 36 common clinical uses, stress reduction, wellbeing and self-esteem-enhancement, surgery preparations, anxiety interventions, mindfulness facilitation, and labor and childbirth applications were the most frequently rated as highly effective (each by ≥70% of raters) in the clinicians' own experience. Adverse hypnosis-associated effects had been encountered by 55% of clinicians but were generally short-lived and very rarely judged as serious. The most common hypnosis approaches used were Ericksonian (71%), hypnotic relaxation therapy (55%), and traditional hypnosis (50%). Almost all respondents reported regularly using other therapeutic modalities alongside hypnosis. Among a range of client variables potentially affecting therapy, most clinicians rated hypnotist-client rapport (88%) and client motivation (75%) as very or extremely important factors for successful hypnotherapy. The majority of respondents had conducted hypnosis treatment via teletherapy, and 54% of those estimated it to be as effective as in-person treatment.

Objective: Gut-directed hypnotherapy (GDH) is an evidence-based treatment for irritable bowel syndrome (IBS). Adoption of remote GDH has been accelerated by the COVID-19 pandemic. We aimed to evaluate patient experience and satisfaction following remote GDH., Design: On completing 12 sessions of remote GDH via Skype using the Manchester protocol, patients with refractory IBS completed a feedback form on their experience. The proportion reporting positive outcomes (≥30% improvement in global IBS symptoms or abdominal pain, satisfaction, recommendation to family/friends) were compared by patient factors (age, gender, proximity, preferences)., Results: Of 52 patients completing the feedback form, 27 (52%) indicated that they would have opted for remote over face-to-face GDH, regardless of the pandemic situation. On a five-point scale (5=easy), patients rated the platform easy-to-use (mean 4.5±0.8) without impairment of communication (mean rating 4.6±0.8). Following remote GDH, 30/52 (58%) reported ≥30% global IBS symptom improvement, and 24/52 (46%) reported ≥30% pain reduction. 90% would recommend remote GDH to others. Only 39% felt they would have benefitted more from face to face. Those who would have chosen remote GDH regardless of the pandemic were more likely to be satisfied (p=0.01). Age, gender and proximity did not influence outcomes, satisfaction and likelihood of recommending remote GDH to others. Difficulties during remote sessions were infrequent in both those that were satisfied, and those that would have preferred face to face., Conclusion: These data support the need to continue developing remote GDH in the post-COVID era but suggest that there is still a role for face-to-face GDH, with patient choice being an important factor., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: The COVID-19 pandemic caused unprecedented disruption to healthcare services worldwide with well-documented detrimental effects on mental health. Patients with refractory disorders of gut-brain interaction such as Irritable Bowel Syndrome (IBS) seen in tertiary care tend to exhibit higher levels of psychological comorbidity, but the impact of the pandemic on IBS symptom severity in tertiary care is unknown., Methods: As part of routine clinical care, consecutive tertiary referrals with refractory IBS patients prospectively completed a series of baseline questionnaires including IBS symptom severity score (IBS-SSS), non-colonic symptom score, Hospital Anxiety and Depression (HAD), and Illness impact scores. The symptom severity questionnaire data were compared for consecutive patients seen in tertiary care 12 months before and after the onset of COVID-19 pandemic restrictions., Key Results: Of 190 consecutive tertiary referrals with IBS, those seen during the pandemic had greater IBS severity (IBS-SSS: 352 vs. 318, p = 0.03), more severe extra-intestinal symptoms (non-colonic score: 269 vs. 225, p = 0.03), sleep difficulties (p = 0.03), helplessness and loss of control (p = 0.02), but similar HAD-Anxiety (p = 0.96) and HAD-Depression (p = 0.84) scores. During the pandemic, unmarried patients (p = 0.03), and keyworkers (p = 0.0038) had greater IBS severity., Conclusions and Inferences: This study has shown for the first time that patients seen in tertiary care with refractory IBS during the COVID-19 pandemic had a significantly higher symptom burden emphasizing the importance of gut-brain axis in IBS. Furthermore, lack of support and perceived loss of control appear to be contributory factors., (© 2022 The Authors. Neurogastroenterology & Motility published by John Wiley & Sons Ltd.)

Background and Aim: Recent studies have highlighted the high worldwide prevalence of irritable bowel syndrome (IBS) and disparities in its management between ethnic groups. For instance, gut-directed hypnotherapy (GDH), one of the most effective evidence-based treatments for IBS, is not recommended in Asian countries partly due to lack of population-specific outcome data. In this context, we evaluated the outcomes of GDH in an Asian population., Methods: Consecutive British Asian patients with refractory IBS who received 12-sessions of GDH using the Manchester protocol were included. Patients were treated by a team including a therapist able to speak several Asian languages. All patients prospectively completed the following questionnaires before and after GDH: IBS symptom severity score (IBS-SSS), hospital anxiety and depression scale (HADS), non-colonic symptom score, and the quality-of-life (QOL) score. The primary outcome measure was response to GDH defined by ≥50-point reduction in IBS-SSS. Pre- and post-treatment data were compared statistically., Results: Forty-four Asian patients with IBS (age 49 ± 13 years; 29 [66%] female; baseline IBS-SSS: 332.8 ± 94.6) completed GDH. Overall, 37 of 44 (84%) achieved a ≥50-point reduction in IBS-SSS and 25 of 44 (57%) achieved ≥30% reduction in abdominal pain scores. Following GDH, there were also significant mean improvements in IBS-SSS (-132.1, P  < 0.0001), non-colonic symptom score ( P  < 0.0001), QOL score ( P  < 0.0001), HADS-anxiety ( P  < 0.0001), and HADS-depression ( P  < 0.0001), compared with baseline., Conclusion: Regardless of the ethnicity of the therapist, GDH was highly effective with similar response rates to outcomes in other IBS populations, supporting the development of GDH in Asian countries., (© 2022 The Authors.

Research on the efficacy of hypnosis applications continues to grow, but there remain major gaps between the science and clinical practice. One challenge has been a lack of consensus on which applications of hypnosis are efficacious based on research evidence. In 2018, 6 major hypnosis organizations collaborated to form the Task Force for Establishing Efficacy Standards for Clinical Hypnosis. This paper describes a Guideline for the Assessment of Efficacy of Clinical Hypnosis Applications developed by the Task Force, which makes 10 specific recommendations. The guideline is intended to be a tool for those who want to assess the quality of existing evidence on the efficacy of clinical hypnosis for any particular indication. The paper also discusses methodological issues in the interpretation and implementation of these guidelines. Future papers will report on the other products of the Hypnosis Efficacy Task Force, such as best practice recommendations for outcomes research in hypnosis and an international survey of researchers and clinicians on current practice and attitudes about hypnosis.

Background: Gas-related symptoms (GRS) are common in the general population (GPop) and among patients with disorders of gut-brain interactions but there is no patient-reported outcome evaluating these symptoms and their impact on daily life. We have previously developed a 43-item intestinal gas questionnaire (IGQ). The aim of the present study is to perform a psychometric validation of this instrument., Methods: Participants (119 from the GPop and 186 irritable bowel syndrome (IBS) patients) were recruited from 3 countries (UK, Spain, France). IBS patients fulfilled ROME IV criteria with an IBS severity score between 150 and 300. Participants completed the IGQ, the functional Digestive Disorders Quality of Life (FDDQL), and the EQ-5D. A subgroup (n = 90) repeated the IGQ completion after 7 days on paper or electronically., Results: From the original IGQ questionnaire, 26 items were deleted because of poor performance. Confirmatory factorial analysis on the remaining 17 items (7 symptom and 10 impact items) yielded a 6-factor structure accounting for 67% of the variance for bloating (6 items), flatulence (3), belching (2), bad breath (2), stomach rumbling (2), and difficult gas evacuation (2). Global score (0-100) was worse among IBS vs GPop (40 ± 15 vs 33 ± 17; p = 0.0016). At the second visit, the intraclass correlation coefficient of IGQ scores was between 0.71 and 0.86 (n = 67) for test-retest reliability and 0.61-0.87 (n = 64) for equivalence between electronic and paper versions of IGQ., Conclusion: The IGQ available in paper and electronic versions in 3 languages is a robust instrument for capturing and measuring GRS and their impact on daily life., (© 2021 The Authors.

Introduction: Numerous studies have shown that hypnotherapy (HT) is effective in irritable bowel syndrome (IBS) using traditional symptom severity end points. However, there is now interest in capturing the patient's perception of their illness and treatment because what patients expect from their treatment may differ from that of their healthcare provider., Objective: To record patient perceptions and expectations of hypnotherapy as well as their symptom response., Methods: 150 consecutive IBS patients (116 females, 34 males, aged 16-81 years) receiving hypnotherapy completed questionnaires recording IBS symptom severity, quality of life, noncolonic symptoms, anxiety and depression levels before and after treatment. Their expectations and perceptions of HT were also recorded, including a free text reflection., Results: 121 patients (81%) responded to treatment consistent with our previous experience. Symptom severity scores, noncolonic symptoms, quality of life, anxiety and depression significantly all improved after HT ( p  < 0.001). Expectancy of an improvement with hypnotherapy was greater in those who did not respond to treatment (63%) than those who did (57%, p  < 0.001). Scepticism and apprehension were common before treatment and replaced with enthusiasm afterwards. Free text responses after treatment were overwhelmingly positive. Patients also reported a variety of other benefits and even 20 of 29 symptom nonresponders (70%) still considered treatment worthwhile., Conclusion: Although initially perceived negatively, hypnotherapy improved symptoms and resulted in a wide range of additional benefits. Expectation did not necessarily influence outcome. Recording IBS symptoms alone does not fully capture the patient's experience of treatment and needs to be considered in future research., Competing Interests: Conflict of interest statement: The authors declared no potential conflicts of interest with respect to the research, authorship and/or publication of this article., (© The Author(s), 2022.)

Irritable bowel syndrome (IBS) and non-alcoholic fatty liver disease (NAFLD) are amongst the most common gastrointestinal and liver conditions encountered in primary and secondary care. Recently, there has been interest in the apparent co-incidence of NAFLD in patients with IBS mainly driven by improved understanding of their shared risk factors and pathophysiology. In this paper we summarize the shared risk factors which include; overlapping nutritional and dietary factors as well as shared putative mechanisms of pathophysiology. These include changes in the gut microbiome, gut permeability, immunity, small bowel bacterial overgrowth and bile acid metabolism. This paper describes how these shared risk factors and etiological factors may have practical clinical implications for these highly prevalent conditions. It also highlights some of the limitations of current epidemiological data relating to estimates of the overlapping prevalence of the two conditions which have resulted in inconsistent results and, therefore the need for further research. Early recognition and management of the overlap could potentially have impacts on treatment outcomes, compliance and morbidity of both conditions. Patients with known IBS who have abnormal liver function tests or significant risk factors for NAFLD should be investigated appropriately for this possibility. Similarly, IBS should be considered in patients with NAFLD and symptoms of abdominal pain associated with defecation, an altered bowel habit and bloating., Competing Interests: Conflict-of-interest statement: None of the authors have any conflicts of interest to disclose., (©The Author(s) 2021.
