Probiotics for fibromyalgia: study design for a pilot double-blind, randomized controlled trial

Area of Science:

• Neuroscience
• Gastroenterology
• Microbiology

Background:

• Fibromyalgia syndrome (FMS) is a chronic pain disorder with emotional and cognitive deficits.
• FMS patients frequently experience gastrointestinal symptoms.
• The gut-microbiota-brain axis influences brain functions, suggesting a potential role for probiotics.

Purpose of the Study:

• To evaluate the effects of probiotic therapy on physical, emotional, and cognitive symptoms in FMS patients.
• To explore the impact of probiotics on the gut-brain axis in FMS.
• To provide the first evidence on probiotic use for FMS.

Main Methods:

• A double-blind, placebo-controlled, randomized pilot study design.
• Validated questionnaires, cognitive tasks (E-Prime), and biological measures (urine cortisol, stool samples) were used.
• Eight weeks of probiotic therapy compared to placebo.

Main Results:

• The study hypothesizes improved cognitive task performance and enhanced emotional and physical symptoms in the probiotic group.
• Biological markers will be analyzed to correlate with symptom changes.
• This study aims to establish the efficacy of probiotics in managing FMS.

Conclusions:

• This is the first pilot study to assess probiotics for FMS.
• Results are expected to enhance understanding of the gut-brain axis in FMS.
• The findings may pave the way for novel therapeutic strategies for FMS.
