Itch Characteristics in Five Dermatoses: Non-atopic Eczema, Atopic Dermatitis, Urticaria, Psoriasis and Scabies

Abstract
International audienceItch is a frequent symptom in many diseases. Some studies have used questionnaires to evaluate pruritus by targeting a single type of dermatitis, for example, studying atopic dermatitis (AD) with the "Eppendorf Itch Questionnaire"(1, 2), and uraemic pruritus (3). Questionnaires have also been used to study psoriasis (4) and urticaria (5). The pathophysiological mechanisms of itch, especially with regard to the mediators and transmitters involved, can vary according to the itch-inducing disease. It is possible that itching sensations may be experienced differently by each patient and depending on the underlying disease. O'Neill et al. (6) and Reich et al. (7) have shown that itching sensations can vary between various skin diseases. The present study used an exploratory approach to highlight the qualitative (symptomatological) features of pruritus in different dermatoses, using a non-validated questionnaire in French, adapted from previous questionnaires (1, 2)
