Study summary

This pilot study plan to investigate the sympathovagal balance in women affected by Irritable Bowel Syndrome (IBS), and to evaluate the effect of 6 months of trans-cutaneous vagal nerve electrical stimulation on digestive physiology (intestinal transit time, intestinal mucosal permeability, systemic and local inflammation), symptoms and quality of life.

The safety of the electrical stimulation of the left vagal nerve will also be evaluated.

Ten women, age between 18 and 60, will be included.

What researchers measure

Primary outcomes

  1. Improvement of clinical symptoms of IBS, based on the evolution of symptom score (Francis) and symptom scale (UCLA-SSS)

    Time frame: 3 and 6 months after the beginning of electrical stimulation

Secondary outcomes

  1. Safety and tolerance of trans-cutaneous nerve stimulation as measured by any symptom occurring in relation with electrical stimulation, number of hours per day of system use

    Any symptom occurring in relation with electrical stimulation, number of hours per day of system use

    Time frame: 6 months

  2. Evolution of digestive physiology during vagal nerve stimulation

    Digestive physiology is evaluated by intestinal transit time with Smartpill capsule, lactuose/mannitol intestinal permeability test, fecal calprotectin and blood cytokines

    Time frame: 3 and 6 months

  3. Effect of vagal nerve stimulation on quality of life

    Quality of life and psychological questionnaires

    Time frame: 3 and 6 months

  4. Evaluation of sympatho-vagal balance

    Measurement by nocturnal EKG Holter of the variability of the interval RR, as a marker of the sympatho-vagal balance

    Time frame: 0, 3 and 6 months
