Project description:BACKGROUND: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder in children. Recently, probiotics have been suggested as a treatment option for gastrointestinal disorders. The most effective species and the most appropriate doses are still unknown. OBJECTIVE: The aim of this study was to assess the effects of Lactobacillus GG (LGG) for treating IBS in pediatric patients. METHODS: In a controlled, double blind, randomized trial, patients with IBS diagnosed by Rome III criteria from August 2012 to September 2012 at Dr. Sheikh Hospital, Mashhad University of Medical Sciences, Iran, were assigned to one of two groups, i.e., intervention and control groups. For four weeks, the intervention group received a probiotic in capsule form that contained LGG at a concentration of 1×10(10) cfu/ml bacteria. For the same period, the control group received a placebo capsule that had the same shape and color but only contained inulin, which also was present in the LGG capsules. The primary outcome was any change in the severity of the patients' pain, and we used a five-point Likert scale to evaluate the severity of their pain. Secondary outcomes were ghanges of the functional scale, stool patterns, and associated problems. RESULTS: Fifty-two patients participated in the study, and 26 patients were assigned randomly to each of the two groups. The severity of the patients' pain decreased significantly in the intervention group after one, two, three, and four weeks of treatment, as indicated by P-values of 0.01, 0.00, 0.00, and 0.00, respectively. Also, there was significant improvement in the functional scale after two weeks of treatment (P-value ≤ 0.00). CONCLUSION: Lactobacillus GG at a concentration of 1×10(10) cfu/ml for a period of four weeks can lessen the severity of the patients' pain and improve the functional scale in patients with irritable bowel syndrome. Probiotics can have therapeutic effects for IBS patients.

Project description:Placebo treatment can significantly influence subjective symptoms. However, it is widely believed that response to placebo requires concealment or deception. We tested whether open-label placebo (non-deceptive and non-concealed administration) is superior to a no-treatment control with matched patient-provider interactions in the treatment of irritable bowel syndrome (IBS).Two-group, randomized, controlled three week trial (August 2009-April 2010) conducted at a single academic center, involving 80 primarily female (70%) patients, mean age 47 ± 18 with IBS diagnosed by Rome III criteria and with a score ? 150 on the IBS Symptom Severity Scale (IBS-SSS). Patients were randomized to either open-label placebo pills presented as "placebo pills made of an inert substance, like sugar pills, that have been shown in clinical studies to produce significant improvement in IBS symptoms through mind-body self-healing processes" or no-treatment controls with the same quality of interaction with providers. The primary outcome was IBS Global Improvement Scale (IBS-GIS). Secondary measures were IBS Symptom Severity Scale (IBS-SSS), IBS Adequate Relief (IBS-AR) and IBS Quality of Life (IBS-QoL).Open-label placebo produced significantly higher mean (±SD) global improvement scores (IBS-GIS) at both 11-day midpoint (5.2 ± 1.0 vs. 4.0 ± 1.1, p<.001) and at 21-day endpoint (5.0 ± 1.5 vs. 3.9 ± 1.3, p =?.002). Significant results were also observed at both time points for reduced symptom severity (IBS-SSS, p =?.008 and p =?.03) and adequate relief (IBS-AR, p =?.02 and p =?.03); and a trend favoring open-label placebo was observed for quality of life (IBS-QoL) at the 21-day endpoint (p =?.08).Placebos administered without deception may be an effective treatment for IBS. Further research is warranted in IBS, and perhaps other conditions, to elucidate whether physicians can benefit patients using placebos consistent with informed consent.ClinicalTrials.gov NCT01010191.

Project description:Current clinical guidelines identify several psychological treatments for irritable bowel syndrome (IBS). IBS patients, however, have elevated trauma, life stress, relationship conflicts, and emotional avoidance, which few therapies directly target. We tested the effects of emotional awareness and expression training (EAET) compared to an evidence-based comparison condition-relaxation training-and a waitlist control condition.Adults with IBS (N=106; 80% female, Mean age=36 years) were randomized to EAET, relaxation training, or waitlist control. Both EAET and relaxation training were administered in three, weekly, 50-minute, individual sessions. All patients completed the IBS Symptom Severity Scale (primary outcome), IBS Quality of Life, and Brief Symptom Inventory (anxiety, depressive, and hostility symptoms) at pretreatment and at 2 weeks posttreatment and 10 weeks follow-up (primary endpoint).Compared to waitlist controls, EAET, but not relaxation training, significantly reduced IBS symptom severity at 10-week follow-up. Both EAET and relaxation training improved quality of life at follow-up. Finally, EAET did not reduce psychological symptoms, whereas relaxation training reduced depressive symptoms at follow-up (and anxiety symptoms at posttreatment).Brief emotional awareness and expression training that targeted trauma and emotional conflicts reduced somatic symptoms and improved quality of life in patients with IBS. This emotion-focused approach may be considered an additional treatment option for IBS, although research should compare EAET to a full cognitive-behavioral protocol and determine which patients are best suited for each approach.

Project description:BackgroundIrritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by abdominal pain and change of bowel habit without organic disease. A global perspective given by the World Gastroenterology Organization (WGO) points out that IBS can impact the quality of an individual's daily life, cause socioeconomic problems and potentially impair the patient-physician relationship. It remains a problem to treat IBS due to the complicated pathophysiology. Acupuncture is an alternative therapy recommended for IBS. The aim of this study is to investigate the efficacy and safety of acupuncture therapy for patients with IBS. We also want to explore the correlation between IBS-gene subtypes and acupuncture effect.Methods/designA multicenter randomized controlled trial will be performed in seven hospitals. Six hundred participants will be stratified into two strata (IBS-C or IBS-D). Then, patients within each stratum will be divided into an experimental group and a control group randomly. The experimental group is treated with acupuncture while the control group is treated with Western medicine. All the patients will receive a 6-week treatment and a 3-month follow-up. The primary outcome is the IBS-Symptom Severity Score (IBS-SSS), the secondary outcome is the score of the IBS-Quality of Life (IBS-QoL).The correlation between IBS-gene subtypes and acupuncture effect will be detected based on polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Outcome measures (including primary and secondary outcome measures) are collected at baseline,1 week, 2 weeks, 4 weeks, and 6 weeks of the intervention, and 12 weeks after the intervention.DiscussionThis is a multicenter randomized controlled trial for IBS in China. It may clarify the efficacy of acupuncture as an alternative therapy for IBS. This is the first time ever that the potential mechanism of IBS based on genomics has been investigated.Trial registrationChinese Clinical Trials Register, ID: ChiCTR-IOR-15006259 .

Project description:ObjectiveTo investigate whether placebo effects can experimentally be separated into the response to three components-assessment and observation, a therapeutic ritual (placebo treatment), and a supportive patient-practitioner relationship-and then progressively combined to produce incremental clinical improvement in patients with irritable bowel syndrome. To assess the relative magnitude of these components.DesignA six week single blind three arm randomised controlled trial.SettingAcademic medical centre.Participants262 adults (76% women), mean (SD) age 39 (14), diagnosed by Rome II criteria for and with a score of > or =150 on the symptom severity scale.InterventionsFor three weeks either waiting list (observation), placebo acupuncture alone ("limited"), or placebo acupuncture with a patient-practitioner relationship augmented by warmth, attention, and confidence ("augmented"). At three weeks, half of the patients were randomly assigned to continue in their originally assigned group for an additional three weeks.Main outcome measuresGlobal improvement scale (range 1-7), adequate relief of symptoms, symptom severity score, and quality of life.ResultsAt three weeks, scores on the global improvement scale were 3.8 (SD 1.0) v 4.3 (SD 1.4) v 5.0 (SD 1.3) for waiting list versus "limited" versus "augmented," respectively (P<0.001 for trend). The proportion of patients reporting adequate relief showed a similar pattern: 28% on waiting list, 44% in limited group, and 62% in augmented group (P<0.001 for trend). The same trend in response existed in symptom severity score (30 (63) v 42 (67) v 82 (89), P<0.001) and quality of life (3.6 (8.1) v 4.1 (9.4) v 9.3 (14.0), P<0.001). All pairwise comparisons between augmented and limited patient-practitioner relationship were significant: global improvement scale (P<0.001), adequate relief of symptoms (P<0.001), symptom severity score (P=0.007), quality of life (P=0.01). Results were similar at six week follow-up.ConclusionFactors contributing to the placebo effect can be progressively combined in a manner resembling a graded dose escalation of component parts. Non-specific effects can produce statistically and clinically significant outcomes and the patient-practitioner relationship is the most robust component.Trial registrationClinical Trials NCT00065403.

Project description:BackgroundPatients with irritable bowel syndrome (IBS) experience abdominal pain, altered bowel habits, and defecation-related anxiety, which can result in reduced productivity and impaired health-related quality of life (HRQL). Cognitive behavioral therapy (CBT) has been shown to reduce symptoms of IBS and to improve HRQL, but access to qualified therapists is limited. Smartphone-based digital therapeutic interventions have potential to increase access to guided CBT at scale, but require careful study to assess their benefits and risks.ObjectiveThe aim of this study was to test the efficacy of a novel app, Zemedy, as a mobile digital therapeutic that delivers a comprehensive CBT program to individuals with IBS.MethodsThis was a crossover randomized controlled trial. Participants were recruited online and randomly allocated to either immediate treatment (n=62) or waitlist control (n=59) groups. The Zemedy app consists of 8 modules focusing on psychoeducation, relaxation training, exercise, the cognitive model of stress management, applying CBT to IBS symptoms, reducing avoidance through exposure therapy, behavioral experiments, and information about diet. Users interact with a chatbot that presents the information and encourages specific plans, homework, and exercises. The treatment was fully automated, with no therapist involvement or communication. At baseline and after 8 weeks, participants were asked to complete the battery of primary (Irritable Bowel Syndrome Quality of Life [IBS-QOL], Gastrointestinal Symptom Rating Scale [GSRS]) and secondary (Fear of Food Questionnaire [FFQ], Visceral Sensitivity Index [VSI], Gastrointestinal Cognition Questionnaire [GI-COG], Depression Anxiety Stress Scale [DASS], and Patient Health Questionnaire-9 [PHQ-9]) outcome measures. Waitlist controls were then offered the opportunity to crossover to treatment. All participants were assessed once more at 3 months posttreatment.ResultsBoth intention-to-treat and completer analyses at posttreatment revealed significant improvement for the immediate treatment group compared to the waitlist control group on both primary and secondary outcome measures. Gains were generally maintained at 3 months posttreatment. Scores on the GSRS, IBS-QoL, GI-COG, VSI, and FFQ all improved significantly more in the treatment group (F1,79=20.49, P<.001, Cohen d=1.01; F1,79=20.12, P<.001, d=1.25; F1,79=34.71, P<.001, d=1.47; F1,79=18.7, P<.001, d=1.07; and F1,79=12.13, P=.001, d=0.62, respectively). Depression improved significantly as measured by the PHQ-9 (F1,79=10.5, P=.002, d=1.07), and the DASS Depression (F1,79=6.03, P=.02, d=.83) and Stress (F1,79=4.47, P=.04, d=0.65) subscales in the completer analysis but not in the intention-to-treat analysis. The impact of treatment on HRQL was mediated by reductions in catastrophizing and visceral sensitivity.ConclusionsDespite its relatively benign physical profile, IBS can be an extraordinarily debilitating condition. Zemedy is an effective modality to deliver CBT for individuals with IBS, and could increase accessibility of this evidence-based treatment.Trial registrationClinicalTrials.gov NCT04170686; https://www.clinicaltrials.gov/ct2/show/NCT04170686.

Project description:IntroductionResearch in recent years has shown the potential benefits of fecal microbiota transplantation (FMT) for irritable bowel syndrome (IBS). Acute infectious gastroenteritis is a well-established risk factor for developing such forms of IBS as post-infectious IBS (PI-IBS). However, the effective use of FMT in patients with IP-IBS has not yet been clarified.AimThe study aimed to conduct a single-center, randomized clinical trial (RCT) to assess FMT's safety, clinical and microbiological efficacy in patients with PI-IBS.Materials and methodsPatients with PI-IBS were randomized into two groups: I (standard-care, n = 29) were prescribed basic therapy, namely a low FODMAP diet, as well as Otilonium Bromide (1 tablet TID) and a multi-strain probiotic (1 capsule BID) for 1 month; II (FMT group, n = 30), each patient with PI-IBS underwent a single FMT procedure with fresh material by colonoscopy. All patients underwent bacteriological examination of feces for quantitative and qualitative microbiota composition changes. The clinical efficacy of treatment was evaluated according to the dynamics of abdominal symptoms, measured using the IBS-SSS scale, fatigue reduction (FAS scale), and a change in the quality of life (IBS-QoL scale).ResultsFMT was associated with rapid onset of the effect, manifested in a significant difference between IBS-SSS points after 2 weeks of intervention (p < 0.001). In other time points (after 4 and 12 weeks) IBS-SSS did not differ significantly across both groups. Only after 3 months of treatment did their QoL exceed its initial level, as well value for 2 and 4 weeks, to a significant extent. The change in the ratio of the main microbial phenotypes in the form of an increase in the relative abundance of Firmicutes and Bacteroidetes was recorded in all patients after 4 weeks. It should be noted that these changes were significant but eventually normalized only in the group of PI-IBS patients who underwent FMT. No serious adverse reactions were noted.ConclusionThis comparative study of the results of FMT use in patients with PI-IBS demonstrated its effectiveness compared to traditional pharmacotherapy, as well as a high degree of safety and good tolerability.

Project description:Background and aimsMany inflammatory bowel disease [IBD] patients in remission have persisting symptoms, compatible with irritable bowel syndrome [IBS-type symptoms]. We aimed to compare the effectiveness of gut-directed hypnotherapy vs standard medical treatment [SMT] for IBS-type symptoms in IBD patients.MethodsIn this multicentre, randomized, controlled, open-label trial, patients aged 12-65 years with IBD in clinical remission [global assessment] and biochemical remission [faecal calprotectin ≤100 µg/g, or ≤200 µg/g without inflammation at endoscopy] with IBS according to Rome III criteria were randomized to hypnotherapy or SMT. Primary outcome was the proportion with ≥50% reduction on a visual analog scale for symptom severity, as measured with the Irritable Bowel Syndrome Severity Scoring System [IBS-SSS] at week 40 [i.e. 6 months after finishing the intervention], compared to baseline. Secondary outcomes included total IBS-SSS score, quality of life, adequate relief, IBS-related cognitions, and depression and anxiety scores.ResultsEighty patients were included, of whom 70 received at least one session of the allocated treatment and were included in the modified intention-to-treat-population. Seven patients were excluded because of missing baseline data required for the primary outcome. The primary outcome was met in nine [27%] of 33 patients randomized to SMT and nine [30%] of 30 patients randomized to hypnotherapy [p = 0.81]. Adequate relief was reported in 60% and 40% of subjects, respectively. Exploratory analyses of secondary outcomes revealed no apparent differences between the two treatment groups.ConclusionsHypnotherapy was not superior to SMT in the treatment of IBS-type symptoms in IBD patients. Both treatment strategies are reasonable options from a clinical perspective.

Project description:AimTo examine the efficacy and safety of otilonium bromide (OB) in treatment-sensitive functional irritable bowel syndrome (IBS) clinical parameters.MethodsNinety-three patients (44.8 ± 12.6 years, 69% female) with IBS symptoms complying with Rome II criteria participated in this double-blind, placebo-controlled, randomised, dose-ranging phase I/II study. Patients were administered OB 20 mg (n = 24), 40 mg (n = 23) and 80 mg (n = 23) tid or placebo (n = 23) in 4 parallel groups for 4 wk. Primary efficacy variables included abdominal discomfort, intestinal habits, number of daily evacuations and stool consistency. Secondary efficacy measures included return to regular intestinal habits and global discomfort. Safety was also assessed.ResultsBaseline clinical characteristics were similar among the 4 groups. Although individual parameters such as intensity and frequency of abdominal discomfort, bloating or pain were reduced by OB over the 4 wk, no significant differences were observed between groups. Similarly, no difference was observed between OB treatment or placebo for mucus in stool and incomplete or difficulty of evacuation. However, evacuation frequency was significantly reduced after 4 wk by 80 mg OB compared to placebo (-8.36% for placebo vs -41.9% for 80 mg OB, P < 0.01). While 21.7% of patients in the placebo group experienced regular intestinal habits after 4 wk, this improvement was greater for patients treated with 40 mg OB (P < 0.01 vs placebo). Furthermore, a dose-dependent reduction in frequency of diarrhoea (χ(2)-test for trend = 11.5, P < 0.001) and an increase in normal stool frequency was observed. Combining individual variables into a global discomfort index revealed significant improvement among increasing OB doses, favouring 40 mg (P = 0.013) and 80 mg OB (P = 0.001) over placebo. No difference was observed between frequency of adverse events for placebo vs OB.ConclusionThis dose-ranging study demonstrates that OB at 40 and 80 mg can improve individual and global clinical symptoms of IBS compared to placebo over a 4-wk period.

Project description:BackgroundIrritable bowel syndrome (IBS) is a worldwide disease with high morbidity. The effect of current treatment with Western medicine is not satisfactory. Although moxibustion treatment is widely used for gastrointestinal diseases, randomized controlled trials on the use of this treatment for IBS are limited. This study aims to evaluate the clinical efficacy and safety of moxibustion treatment in patients with diarrhea-predominant irritable bowel syndrome (IBS-D).Methods/designA multi-center, randomized, single-blind and placebo-controlled trial is employed. 104 cases will be divided into two groups: (1) a mild-warm moxibustion group in which moxa stick is 3-5 cm away from acupuncture points and the skin temperature is maintained at 43 ± 1 °C; and (2) a placebo moxibustion group in which moxa stick is 8-10 cm away from acupuncture points and the skin temperature is maintained at 37 ± 1 °C. Moxibustion is performed on bilateral ST25 and ST36 in the two groups for 30 min each time, three times a week for 6 weeks. The patients are followed up at the 12th and 18th weeks. Adequate relief is used as a primary outcome measure; IBS symptom severity score, Bristol stool form scale, IBS quality-of-life questionnaire, and hospital anxiety and depression scale are used as secondary outcome measures.DiscussionThis study aims to demonstrate the safety and efficacy of moxibustion treatment for IBS-D, which may validate moxibustion as an effective therapy for treating IBS-D.Trial registrationClinicalTrials.gov identifier NCT02421627 (8 April 2015).
