Study of the Microbiological Profile of Stool in Patients With Anorexia Nervosa

Withdrawn

• Conditions: Anorexia Nervosa; Eating Disorder

• Registration Number: NCT03736642
• Lead Sponsor: Centre Hospitalier Universitaire de Saint Etienne

Brief Summary

Anorexia nervosa is an eating disorder whose symptomatology induces a modification of the intestinal microbiota. To date, studies have shown variable profiles without linking them to metabolic and neuropsychological energy phenotyping. This intestinal dysbiosis could be involved in the maintenance of the disorders. Bidirectional communication channels exist between the microbiota, the intestine and the brain. Anomalies in these pathways could explain the impact of the microbiota on the pathophysiology of anorexia nervosa. Therapeutic interventions would then be possible to restore the microbiota in anorexia nervosa and influence the treatment of this disease. This study aims to explore the hypothesis of disruption of the microbiota-intestinal-brain axis transversely and measuring the intestinal microbiota, urinary metabolome, biological factors nutritional, immunological and physiological plasma plasma of the intestine, and finally, the psychological dimensions characteristic of anorexia nervosa.
