- Brief Summary
The investigators have previously studied the efficacy of hyperbaric oxygen therapy (HBOT) as a treatment for Fibromyalgia syndrome (FMS) in a prospective, active control, crossover clinical trial. The results demonstrated significant amelioration of all FMS symptoms, with significant improvement in life quality; furthermore, the investigators were able to demonstrate significant neuroplasticity on SPECT imaging, with a decrease of the hyperactivity in posterior regions and elevation of the reduced activity in frontal areas.
In this study, the investigators intend to both repeat and expand the investigator's previous findings, treating FMS patients with history of emotional trauma with HBOT, while performing an extensive of evaluation both before and after treatment.
In the current study, the investigators plan to compare HBOT to current standard of care of FMS (pharmacological and non - pharmacological).
- Detailed Description
The study will include 60 fibromyalgia patients in whom emotional trauma, such as childhood abuse, could be considered as the trigger for FMS. Each participant will be examined at the time of recruitment and a diagnosis of FMS will be verified, based on the updated 2016 diagnostic criteria. In the current study the investigators will recruit patients not currently being treated with the target medications (Lyrica or Cymbalta).
Patients will undergo randomization upon recruitment to one of the two study groups. One group will proceed to a course of HBOT treatment while the second group will commence with standard treatment for FMS, as outlined in the Israeli guidelines for the diagnosis and treatment of FMS .
HBOT protocol: a total of 60 daily hyperbaric oxygen treatment sessions will be administrated 5 days per week. 60 sessions will include exposure of 90 minutes to 100% at 2 Absolute atmospheres (ATA), with 5 minutes air breaks every 20 minutes.
Pharmaceutical protocol: patients will be offered pharmacological treatment with one of the two medications currently licensed for the treatment of FMS in Israel, i.e. Cymbalta and Lyrica. Treatment with Lyrica will start at a dose of 75 mg twice a day, at morning and at bedtime, while treatment with Cymbalta will start at a dose of 30 mg a day (in the morning). After a period of 2 weeks, patients will be evaluated and dose will be adjusted as necessary and tolerated, up to the maximum dosage recommended for FM. Patients may also be switched from one medication to the other according to clinical judgment of the physician.

Each session will include exposure of 90 minutes to 100% at 2 ATA, with 5 minutes air breaks every 20 minutes Pharmacotherapy Cymbalta / Lyrica - Drug treatment Two medications currently licensed for the treatment of FM in Israel, i.e. Cymbalta and Lyrica. Treatment with Lyrica will start at a dose of 75 mg twice a day, at morning and at bedtime, while treatment with Cymbalta will start at a dose of 30 mg a day (in the morning).

- Primary Outcome Measures
Name Time Method Fibromyalgia Impact Questionnaire (FIQ) questionnaire at 6 months Fibromyalgia Impact Questionnaire (FIQ) questionnaire score at the end of follow up period (HBOT/pharmaceutical). Score range 0-100, higher score means worse outcome
- Secondary Outcome Measures
Name Time Method conditioned pain modulation using Heat test-stimulus (HTS) at baseline, 3 months Following heat pain thresholds assessments, the thermode will be applied on the forearm for 120 seconds at constant temperature. The temperature will be individually adapted to induce a mean pain intensity of 50/100, Participant's pain intensity will be evaluated by numeric pain rating scale (NPRS) ranging from 0 (no pain) to 100 (most intense pain tolerable). The 120-second HTS will be done before and during cold water immersion of the contralateral hand in 10 Celsius degrees, using the same thermode temperature to measure conditioned pain modulation (CPM). CPM efficiency will be evaluated by computing the difference in mean pain intensity induced by the pressure stimulus and the Heat test-stimulus (HTS) before and during the Cold water immersion of the opposite hand. Thus, effective pain inhibitory mechanisms are represented by higher (positive) values
Brain functionality at baseline, 3 months FMRI tasks will evaluate brain function during cognitive (working memory task) and emotional tasks (emotion recognition task)
NeuroTrax at baseline, 3 months computerized cognitive evaluation battery
CANTAB Cambridge Neuropsychological Test Automated Battery at baseline, 3 months computerized cognitive evaluation battery
Heat pain threshold at baseline, 3 months Heat pain threshold is determined as the minimum temperature causing pain. Thermal pain is induced with thermal electrode (thermode). Thermode temperature will initially be set at 32.0°C and gradually increase at a rate of 0.3°C/sec. Participants will be instructed to report when the sensation produced by the thermode changed from heat sensation to pain (heat-pain threshold). This procedure will be conducted three times for every subject and the mean of the trials will be calculated.
Cerebral blood volume at baseline, 3 months Cerebral blood volume (in milliliter) will be measured using perfusion MRI protocol Dynamic susceptibility contrast (DSC).
Brain function imaging at baseline, 3 months Resting state fMRI(rsfMRI or R-fMRI)- a method of functional brain imaging that can be used to evaluate regional interactions that occur when a subject is not performing an explicit task. This resting brain activity is observed through changes in blood flow in the brain which creates what is referred to as a blood-oxygen-level dependent (BOLD) signal that can be measured using functional Magnetic Resonance Imaging (fMRI).
Inflammatory cytokines at baseline, 3 months Blood Tests will include: IL-1, IL-6, Tumor necrosis factor-alpha, C-reactive protein (CRP).
Cerebral blood Flow at baseline, 3 months Cerebral blood volume (in milliliter/min) will be measured using perfusion MRI protocol Dynamic susceptibility contrast (DSC).
