Gender differences in psoriasis: a Swiss online psoriasis survey

Physicians' and patients' perspectives can vary significantly. For a long time, physicians considered psoriasis a non-pruritic dermatosis until a survey found pruritus to be the most bothersome symptom among psoriasis patients. In our study, we wanted to get an insight into the factors that affect patients and evaluate whether gender differences exist. A link of an anonymous online survey (www.fightpsoriasis.ch) with 24 questions was placed on the website of the Swiss Psoriasis and Vitiligo Patient Association (www.spvg.ch) from May 2016 until June 2017. 3164 persons participated in this online survey, of which 1979 were diagnosed with psoriasis. Significantly more females than males were affected by psoriatic pruritus [713 (36%) vs. 500 (25.3%), p ≤ 0.001] and 756 (39.7%) of all patients identified pruritus as the most life quality-limiting factor. Fewer women reported high satisfaction with their therapy compared to men [96 (4.9%) vs. 110 (5.6%), p ≤ 0.015]. Pruritus remains the most bothersome symptom and women were more often affected by it, leading to a lower treatment satisfaction among female patients.
