  • Ages 18 to 50 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • Patients must meet the Rome III criteria for IBS and lack red flag symptoms, such as weight loss, bloody stool, and fever. In the setting of clinical uncertainty on the part of the examining gastroenterologist, laboratory testing or prior medical records may be requested.
  • Upper gastrointestinal symptoms, ie. dyspepsia or heartburn, are acceptable as long as IBS is their most bothersome symptom complex.
  • Subject cannot have completed structured training in MBSR or other mindfulness or meditation.
  • Subject cannot be currently practicing MBSR.
  • A minimal severity score of 75 on the IBS-SSS at screening will be required to ensure at least mild-moderate symptoms at baseline.
  • Literate in English

  • Ambulatory without a need for assistive devices.
  • Able to participate in the sitting and mild yoga positions required for the MBSR course.
  • Right handed due to importance of laterality in brain imaging analysis
  • Not pregnant, nursing or postpartum.
  • No metals in body, including ferrous metallic implants and tattoos
  • No history of claustrophobia.
  • Able to lay still on back for extended period of time ( about 90 minutes).

Who cannot join

  • Planned major medical intervention in the next 6 months (e.g. surgery), or surgery in the past 6 months.
  • Presence of a significant and ongoing medical problem that would interfere with participation in the study or testing the study hypotheses (e.g. major heart disease, neurological disorders, inflammatory bowel disease, etc).
  • Presence of a major psychiatric diagnosis such as schizophrenia, Bipolar disorder, Post-traumatic Stress Disorder, or Obsessive Compulsive disorder. However, subjects with a history of DSMIV diagnosis of Anxiety or Depression, in whom symptoms are not active will be allowed but noted for post-hoc analysis.
  • use of centrally acting medications that will interfere with the neuroimaging testing (e.g. narcotic medications). As in past studies we will allow subjects taking stable doses of antidepressant medications (TCAs, SSRIs, SNRIs) for at least six months prior to study to participate.
  • Body Mass Index greater than 30.
  • Current or past history of chronic pain syndrome other than IBS in the IBS group (pain >6 months at any location).
  • History of gastrointestinal surgery other than uncomplicated appendectomy or cholecystectomy.

About this study

Official title: Neuroimaging Biomarkers of Mind-Body Treatment Response in Chronic Visceral Pain

The purpose of this study is to use functional magnetic resonance imaging (fMRI) to evaluate brain resting state networks, responses to abdominal stimuli and the effect of MBSR Training on these measures. The goal of this study is to identify biomarkers of IBS and assess the responsiveness these biomarkers after MBSR Training. A biomarker, or biological marker, is in general a substance or measure used as an indicator of a biological state. It is a characteristic that is measured and evaluated as an indicator of normal biological processes, disease processes, or responses to a therapeutic intervention, in this case MBSR.

Read the detailed description

Irritable bowel syndrome (IBS) is the most common chronic visceral pain disorder ranking among the most common of all persistent pain disorders with prevalence rates of 8-12% of the population.3 Diagnostic criteria for IBS include persistent abdominal pain and/or discomfort associated with changes in bowel habit. In the majority of patients, symptoms of other co-morbid pain conditions, such as epigastric pain (functional dyspepsia), pelvic pain (IC/PBS) and musculoskeletal pain (FM) are reported. Estimates are that >50% of the U.S. workforce experiences some type of pain and 13% lose productive work time due to pain over a 2 week period, leading to over 60 billion dollars per year in lost productivity costs.4 There are no generally agreed upon biomarkers for IBS, and diagnoses are exclusively based on subjective symptom criteria. As with most of the persistent pain disorders, IBS patients and their providers have increasingly embraced a biopsychosocial model incorporating psychological and social factors along with physiologic factors, and this forms the basis for integrative treatment approaches. This multimodal approach often incorporates Mind-Body treatments, and there is a growing literature showing clinical efficacy in IBS for interventions incorporating such Mind-Body approaches as meditation, hypnosis, yoga and cognitive therapy.5 However, there is little understanding of the physiological mechanisms underlying mind-body therapies, and for this reason optimization of the treatments for specific individuals and populations is difficult.

In this project we aim to use neuroimaging based biomarkers of IBS to examine which of these physiological measures show changes specific to a mind-body treatment with previously documented efficacy, Mindfulness Based Stress Reduction Training or MBSR. MBSR was chosen as a target treatment for several reasons: Recent clinical trial data suggests there is efficacy in improving IBS symptoms with MBSR, it has demonstrated prior success with other chronic pain conditions and there is considerable literature on meditation associated brain changes.

The primary Objective is to validate optimal biomarker candidates by assessment of treatment responsiveness in IBS patients following Mindfulness Based Stress Reduction (MBSR). The secondary objectives are to determine the generality of optimal biomarkers from Aim 1 and 2 and look at factors such as sex, age, co-morbid pain or mood symptoms, and/or baseline disease severity as moderators of the performance of candidate biomarkers.

Also, exploratory analyses will be performed to assess the effect of an 8 week MBSR training on measures of disease cognition, quality of life and mood defined by pre and post test scores on the behavioral measures listed in the study methods.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Validate Optimal Biomarker candidates

    To validate optimal brain biomarker candidates by assessment of treatment responsiveness in IBS patients following and 8 week course in Mindfulness Based Stress Reduction (MBSR).

    Measured: After MBSR training (8 weeks).

Secondary outcomes (1)
  1. Specificity, generality and moderation of biomarker response to MBSR treatment.

    Specificity of biomarker response to MBSR measured by changes in selected biomarker candidates correlation w/improvement in mindfulness at end of treatment \& 3-month f/u.

    Determine generality of optimal biomarkers via examination of factors such as sex, age, co-morbid pain,mood, and/or baseline disease severity, as moderators of biomarker performance.

    Moderation of biomarker performance by symptoms: Disease severity, duration, and comorbid symptoms.

    Measured: Post MBSR training at 3 month follow up.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Validate Optimal Biomarker candidates (time frame: After MBSR training (8 weeks).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 May 2018.
