    Abstract:
    BACKGROUND: It is unknown if health-related quality of life (HRQoL) differs between diseases associated with chronic pruritus (CP). OBJECTIVE: To analyze HRQoL in relation to age, gender, skin lesions (primary vs. scratch-induced secondary) and itch intensity. METHODS: Consecutive patients of our itch clinic were assessed with the Dermatology Life Quality Index (DLQI) and visual analogue scale (VAS). RESULTS: In 510 CP patients (282 females; median age, 61.4 years), DLQI scores and VAS values were highly correlated, irrespective of the type of skin lesion. Overall, women had a lower HRQoL compared to men (females: 10.7 ± 6.7, males: 8.9 ± 6.7), but female gender was only associated with worse quality of life in patients <65 years old. CONCLUSION: HRQoL impairment in CP is highly influenced by pruritus intensity but not to the visible skin lesion or underlying cause. With limitations to item bias, DLQI is a suitable instrument for estimating quality of life impairment by CP.
