Brief Summary

Fibromyalgia syndrome (FMS) is a chronic and heterogeneous disorder characterized primarily by widespread pain, accompanied by sleep disturbances, fatigue, depressive symptoms, and cognitive dysfunction. Although multiple therapeutic options are available, no curative treatment currently exists. Previous studies have demonstrated increased oxidative stress, dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, and a predisposition to sarcopenia in patients with FMS. Ozone therapy has increasingly been used in chronic diseases due to its regulatory effects on oxidative stress. Although ozone is inherently an oxidative molecule, when administered at therapeutic doses it may induce antioxidant responses at the cellular level and exert anti-inflammatory effects by modulating inflammatory mediators. However, limited studies have evaluated the efficacy and underlying mechanisms of major ozone autohemotherapy (MOA) in FMS. This controlled, prospective, single-blind study aims to investigate the effects of major ozone autohemotherapy on clinical parameters of FMS, as well as its impact on HPA axis function and sarcopenia-related parameters. A total of 60 patients with FMS will be enrolled and randomized into two groups: (1) exercise therapy alone and (2) exercise therapy plus major ozone autohemotherapy. MOA will be administered twice weekly for a total of 10 sessions at a dose of 20-40 μg/mL. Participants will be evaluated at baseline, at week 6, and at 3 months. Outcome measures will include Visual Analog Scale (VAS), Fibromyalgia Impact Questionnaire (FIQ), Fatigue Severity Scale (FSS), Pittsburgh Sleep Quality Index (PSQI), Short Form-12 (SF-12), and Hospital Anxiety and Depression Scale (HADS). Morning fasting serum cortisol levels will be measured to assess HPA axis function. Sarcopenia assessment will include handgrip strength measured by Jamar dynamometer, and ultrasonographic evaluation of muscle mass, muscle thickness, pennation angle, fascicle length, echogenicity, and cross-sectional area. Physical performance will be assessed using the Short Physical Performance Battery (SPPB). Unlike previous studies, this trial includes a 3-month follow-up evaluation after completion of ozone therapy to assess longer-term effects. By incorporating objective sarcopenia and endocrine assessments alongside validated clinical scales, the study aims to provide comprehensive evidence regarding the role of major ozone autohemotherapy in FMS management. This will be the first study to specifically evaluate the effects of major ozone autohemotherapy on sarcopenia parameters in patients with FMS.

Outcome Measures

Primary Outcomes (1)

• Change in Fibromyalgia Impact Questionnaire (FIQ) Total Score

  The Fibromyalgia Impact Questionnaire (FIQ) will be used to assess overall disease impact and functional status. The total score ranges from 0 to 100, with higher scores indicating greater disease impact/severity. The primary endpoint is the between-group difference in change in FIQ total score from baseline to Month 3.

  Baseline (Day 0) to Month 3

Secondary Outcomes (14)

• Change in Fatigue Severity Scale (FSS) Score

  Baseline (Day 0), Week 6, and Month 3

• Change in Pittsburgh Sleep Quality Index (PSQI) Global Score

  Baseline (Day 0), Week 6, and Month 3

• Change in Health-Related Quality of Life (SF-12 PCS)

  Baseline (Day 0), Week 6, and Month 3

• Change in Health-Related Quality of Life (SF-12 MCS)

  Baseline (Day 0), Week 6, and Month 3

• Change in Pain Intensity (Visual Analog Scale, VAS)

  Baseline (Day 0), Week 6, and Month 3

Other: Major Ozone Autohemotherapy; Other: Exercise Therapy

Exercise + Placebo Ozone

PLACEBO COMPARATOR

Other: Placebo Ozone Autohemotherapy; Other: Exercise Therapy

Interventions

Major Ozone Autohemotherapy OTHER

Major ozone autohemotherapy will be administered twice weekly for a total of 10 sessions. In each session, 100 mL of venous blood will be withdrawn into a sterile citrate-containing glass bottle, mixed with 100 mL of an ozone-oxygen gas mixture at a concentration of 20-40 μg/mL, and reinfused intravenously over approximately 7-10 minutes. The procedure will be performed by certified physicians according to the Madrid Declaration on Ozone Therapy guidelines.

Exercise + Major Ozone Autohemotherapy

Placebo Ozone Autohemotherapy OTHER

The placebo procedure will be identical to the active major ozone autohemotherapy protocol; however, a non-therapeutic ozone concentration (0.1 μg/mL) will be used. Blood withdrawal, mixing, and reinfusion procedures will be performed in the same manner to maintain blinding.

Exercise + Placebo Ozone

Exercise Therapy OTHER

Participants will undergo a supervised exercise program twice weekly for 3 months. Each 60-minute session will include warm-up walking, aerobic exercise at 60-65% of maximum heart rate, strengthening exercises targeting major muscle groups, and stretching exercises. Exercise intensity will be gradually progressed if tolerated without symptom exacerbation
