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.
