Pruritus is a major symptom of a huge variety of dermatoses. It causes a scratch response, starting the itch-scratch cycle, which in turn aggravate the inflammatory response and exacerbate disease severity Lichen Simplex Chronicus (LSC) is a skin disorder affecting patient's psychosocial and functional status. Pruritus is a diagnostic hallmark for LSH. It is the reason for sleep disturbances, anxiety and depression. Therefore, a clinical investigation of pruritus alongside with a study of their self-reported health status is a necessary precondition for successful therapeutic results.
The aim of the study is to assess the impact of pruritus on quality of life (QoL) of LSC patients` by evaluating the severity of pruritus and sleep disturbance with visual analogue scale (VAS), and verbal rating scale (VRS) and compared it with results from answers to a standardized dermatology-specific quality of life instrument- Dermatology Life Quality Index (DLQI). (Specially answer to question1- symptoms).
