Abstract
BACKGROUND: Chronic itch is a common symptom of inflammatory skin diseases. This study was undertaken to evaluate the presence and intensity of itching in two different cohorts of acne subjects. Additionally, the influence of itching on the psychosocial status of acne individuals was assessed. METHODS: Consecutive acne patients seeking dermatological advice and university students diagnosed with acne during dermatological screening were considered. The clinical and psychological aspects of acne were assessed using a variety of instruments. RESULTS: About 40% of acne subjects in both cohorts reported itching. The mean WI-NRS during the last 3 days in acne patients was 3.83 ± 2.31 points (mild itch) and was significantly more severe (p < 0.001) than in university students diagnosed with acne (2.09 ± 1.29 points). Itch intensity did not depend on the clinical severity of acne. In consecutive acne patients, itch intensity correlated with quality-of-life impairments (assessed using DLQI and CADI) and HADS scores. There was no correlation between itch intensity and stigmatization levels. CONCLUSIONS: Itching seems to be a common phenomenon in acne sufferers. Acne itch significantly influences patients' well-being and should be considered in a holistic approach to acne patients.
