Psychogenic & Neurogenic Components in Patients With Psychogenic or

Status Terminated

Clinical Trial Summary

Scientific research on pruritus is in intensive development, with significant advances in understanding its pathophysiology. The causes of pruritus are very huge; they can be classified into different categories; we can find dermatological causes, systemic causes, neuropathic or neurological causes, psychogenic or even idiopathic causes. The diagnosis of psychogenic pruritus is often over stated, when no cause is found; therefore, it is important to see what is really relieving from psychic so as not to over-diagnose and adopt a therapy more in line with the real problem of the patient. In daily practice, it seems to have a tendency to separate psychogenic and neurogenic etiologies in the diagnosis of neuropathic or psychogenic pruritus. In the case of patients with psychogenic pruritus and neuropathic pruritus, no study has attempted to study the respective part of psychogenic and neurogenic components. Consequently, it would therefore be interesting to assess the areas of superposition and distinction of neuropathic and psychogenic pruritus. The aim of this pilot study is to assess the psychogenic and neurogenic components of psychogenic pruritus and neuropathic pruritus in order to improve understanding of the mechanism and therefore their management. The main objective of this study is to highlight the differences and the potential common characteristics between psychogenic and neuropathic pruritus in order to improve the differential diagnosis between these two pathologies. The secondary objective of this study is to describe the psychogenic and neurogenic characteristics of psychogenic and neuropathic pruritus.

Clinical Trial Description

PruriNeuro : Non-interventional single-center prospective study organized and practiced on humans for the development of medical knowledge, in which the data are obtained by validated questionnaires. The duration of participation is estimated at 1 hour. Questionnaires used : - Critères diagnostiques du prurit psychogène (Diagnosis criteria of functional itch disorder or psychogenic pruritus, from the French psychodermatology group) - NP5 questionnaire - Questionnaire de Brest - HADS - TAS-20 - DN4i ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
