简要总结
Fibromyalgia is a medical disorder characterized by chronic widespread pain, and a heightened and painful response to pressure. Fibromyalgia symptoms are not restricted to pain, leading to the use of the alternative term fibromyalgia syndrome for the condition. Other symptoms include functional gastrointestinal pain and discomfort.
The origin of these symptoms is not yet known, and a few hypotheses have been stated. One of the supposed mechanisms that may lead to gastrointestinal hypersensitivity is a chronic, low-grade, intestinal inflammation due to an increased intestinal permeability.
In this study, we hypothesise that the food supplement PERMEAPROTECT (that contains, amongst other nutrients, glutamine and curcumin) contributes to reducing the intestinal permeability and low-grade inflammation, thus improving gastrointestinal quality of life.
详细描述
Patients diagnosed with fibromyalgia will enter the study and follow a run-in phase during which they will all be supplemented with prebiotics, probiotics and grape fruit seed extract for 5 weeks :
- Patients that do not present a satisfactory relief of gastrointestinal symptoms (patient subjective evaluation) will enter the randomised phase after 2 weeks +/- 1 week, at day D0.
- Patients that do present a satisfactory relief of gastrointestinal symptoms (patient subjective evaluation) will exit the study at that point, and follow their usual medical care.
Patients that enter the randomised phase will be supplemented with either PERMEAPROTECT or a PLACEBO, for 5 weeks +/- 1 week. Patients will then follow a 2 weeks +/- 1 week of wash-out, during which no supplementation will be made.
Measures of the outcomes will be made :
- at Day 0 (beginning of supplementation).
- at Day 35 (+/- 7) (end of supplementation).
- at Day 49 (+/- 7) (end of follow-up, end of study)

结局指标
主要结局
Improvement of the Gastrointestinal Quality of Life Index (GIQLI) at the end of the supplementation period (5 weeks), compared with baseline.
时间窗: Day D0; Day D35 (+/-7)
The Gastrointestinal Quality of Life Index is a validated questionnaire of 36 questions related to gastrointestinal pain and discomfort, including accelerated or stalled transit, assessing the impact of these symptoms on the quality of life.
次要结局
- Improvement of the general Quality of Life, measured by the Medical Outcome Study Short Form (MOS SF-36), at the end of the supplementation period (5 weeks), and at the en of follow-up (2 weeks), compared with baseline(Day D0; Day D35 (+/-7); Day D49 (+/-7))
- Improvement of the Gastrointestinal Quality of Life Index (GIQLI) at end of follow-up (2 weeks), compared with baseline(Day D0; Day D49 (+/-7))
- Reduction of the serum C-reactive Protein (usCRP), measured by the ultra-sensitive method, at the end of the supplementation period (5 weeks), and at end of follow-up (2 weeks), compared with baseline.(Day D0; Day D35 (+/-7);)
- Reduction of blood oxidative stress markers (reduced glutathione, oxidized glutathione and malondialdehyde), at the end of the supplementation period (5 weeks), and at end of follow-up (2 weeks), compared with baseline.(Day D0; Day D35 (+/-7))
- Improvement of the Impact of Fibromyalgia on the Quality of life, measured by the Fibromyalgia Impact Questionnaire (FIQ), at the end of the supplementation period (5 weeks), and at end of follow-up (2 weeks), compared with baseline.(Day D0; Day D35 (+/-7); Day D49 (+/-7))
- Improvement of the subjective evaluation, by the patient, of the satisfactory relief of gastrointestinal symptoms, at the end of the supplementation period (5 weeks), and at end of follow-up (2 weeks), compared with baseline.(Day D0; Day D35 (+/-7); Day D49 (+/-7))
- Improvement of the subjective evaluation, by the patient, of the satisfactory relief of gastrointestinal pain, at the end of the supplementation period (5 weeks), and at end of follow-up (2 weeks), compared with baseline.(Day D0; Day D35 (+/-7); Day D49 (+/-7))
- Reduction of the intestinal permeability, measured by the urinary ratio of lactulose/mannitol, at the end of the supplementation period (5 weeks), and at end of follow-up (2 weeks), compared with baseline.(Day D0; Day D35 (+/-7))
- Improvement of the subjective evaluation, by the patient, of the intensity of gastrointestinal symptoms, at the end of the supplementation period (5 weeks), and at end of follow-up (2 weeks), compared with baseline.(Day D0; Day D35 (+/-7); Day D49 (+/-7))
