Chronic Pruritus

Very little is currently known about the pathophysiology of pruritus sine materia according to the etiology. The creation of this cohort should make it possible to improve our clinical and biological knowledge according to the etiology, by collecting blood, skin, feces, and clinical data.

Pruritus is a common symptom of numerous dermatological and non-dermatological conditions. Current treatments for chronic pruritus (CP) are often not fully effective and may have burdensome side effects. Recently, the trauma exposure technique Eye Movement Desensitization and Reprocessing (EMDR) that is recommended as first line treatment for posttraumatic stress disorder has been reported to be also effective in the treatment of CP in anecdotal clinical case observations. However, to the best of the investigator's knowledge, the efficacy of EMDR in CP has not yet been systematically explored. This study aims at addressing this unmet need in a prospective pilot study comparing EMDR versus treatment as usual (TAU).
