EUDAIMON: Cost-utility and Biological Underpinnings of MBSR in Fibromyalgia Syndrome
Study Details
Study Description
Brief Summary
Purpose:
Fibromyalgia syndrome (FMS) is a disabling condition mainly characterized by chronic widespread pain, disturbed sleep, fatigue, and distress. The estimated overall prevalence of FMS in Europe is 2.9% and it incurs in high personal, social and healthcare costs. Available treatments in FMS are not curative and there is some evidence of positive effects of mindfulness-based stress reduction (MBSR) in patients with chronic pain and FMS. Nevertheless, although promising, the positive findings obtained in previous studies implementing mindfulness-based interventions in patients with FMS have to be interpreted with caution due to important methodological limitations (e.g. absence of randomization, high attrition rates, or small sample sizes). Therefore, further research in larger studies using more adequate methodologies is warranted. Furthermore, little is known about putative neurobiological processes underpinning the effects of mindfulness training in patients with chronic pain.
Aims: The aim of this randomized, controlled trial (RCT) is two-fold: firstly, to assess the effectiveness and cost-utility of MBSR added to treatment as usual (TAU); and secondly, to evaluate the effects of the compared interventions on neurobiological parameters. Specifically, MBSR will be compared to an active control which was previously reported as a cost-effective intervention (TAU + FibroQol psycho-educational program; Luciano et al., 2013) and also vs. TAU alone (in a 12-month follow-up RCT). Brain structure and function of pain-relevant areas and levels of inflammation markers (cytokines) will be assessed pre-post interventions in half of the study participants.
Methods:
Design: RCT with three arms:
-
TAU + MBSR,
-
TAU + FibroQoL and
-
TAU.
Sample: 180 adults with FMS according to the ACR 1990 criteria (N=60 for each study arm) will be recruited from from the Parc Sanitari Sant Joan de Déu Rheumatology Service, Sant Boi de Llobregat, Spain. Half of the participants will be randomly selected to participate in the neurobiological pre-post evaluation (N= 30 each group). All patients will be assessed at baseline, post-intervention and 12-month follow-up for clinical variables, prep-post intervention for biomarkers study, and baseline and 12-month follow-up for cost-related variables.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Mindfulness-Based Stress Reduction Mindfulness-Based Stress Reduction (MBSR) The MBSR consists in eight 2-h group sessions and an all-day mindfulness retreat, and offers intensive and structured training in mindfulness meditation to help patients to relate to their physical and psychological conditions in more accepting and nonjudgmental ways. Participants will be encouraged to engage in home mindfulness practices. Sessions will be lead by 4 MBSR accredited instructors. |
Behavioral: MBSR
Session 1: Recognising the present moment Session 2: Engaging with the breath Session 3: Practice, practice, practice Session 4: Stress and the flow of emotions Session 5: Stress and thoughts: finding another place to stand Session 6: Interpersonal mindfulness / mindful communication. Session 7: Applying mindfulness Session 8: Making mindfulness a part of your life
Drug: TAU
In Spain the treatment as usual provided in FMS is mainly pharmacological and adjusted to the symptomatic profile of the patient. Counselling about aerobic exercise adjusted to patients' physical limitations is usually also provided.

Active Comparator: Psycho-educational Program Psycho-educational Program (FibroQol) It consists of eight 2-h group sessions including information about FMS (4 sessions) based on a consensus document of the Health Department of Catalonia + autogenic relaxation (4 sessions). |
Behavioral: FibroQol
Session 1: General information. Expectations of the patients. History of the illness. Principal and secondary symptoms in FM. Physiological mechanisms involved in the genesis of pain.
Session 2: Relaxation training-I. Session 3: Diagnosis. Pharmacological and non-pharmacological treatments. Prognosis. Current model of health care in Catalonia. Units specialized in the treatment of FM.
Session 4: Relaxation training-II. Session 5: Strategies to increase self-esteem and regulate emotions. Pain experience and recurrent invalidation. Social support (family and friends).
Session 6: Relaxation training-III Session 7: Benefits of physical exercise in FM. Session 8: Relaxation training-IV.
Drug: TAU
In Spain the treatment as usual provided in FMS is mainly pharmacological and adjusted to the symptomatic profile of the patient. Counselling about aerobic exercise adjusted to patients' physical limitations is usually also provided.

Outcome Measures
Primary Outcome Measures
- Effectiveness Evaluation: Revised Fibromyalgia Impact Questionnaire (FIQR) [Change from baseline scores at 12 months]
- Cost-utility: Client Service Receipt Inventory (CSRI) [Change from baseline scores at 12 months]

- Structural neuroimaging: Voxel-Based Morphometry (VBM) [Change from baseline brain gray matter concentration at 2 months]
Analysis of morphometric changes associated with participation in the three study arms voxel-by-voxel across the brain and in functionally-defined brain regions of interest relating to meta-awareness, body awareness, memory consolidation-reconsolidation, and emotion regulation.
- Functional neuroimaging: pulsed continuous arterial spin labeling (pCASL) [Change from baseline regional cerebral blood flow at 2 months]
Analysis of changes in regional cerebral blood flow representing response to treatment throughout the brain and in a priori-specified network of brain regions postulated to underpin the sensory-discriminative, cognitive-evaluative and affective-motivational aspects of the pain experience.
