RESUMO

BACKGROUND: Vitiligo management is challenging and requires long-term adherence of patients who often complain of the burden associated with treatment. OBJECTIVE: To develop and validate a patient reported measurement of the burden of treatment in vitiligo. METHODS: The study was nested within the ComPaRe Vitiligo e-cohort, an online e-cohort of vitiligo patients in France. Items were derived from a literature review and from the qualitative analysis of a survey using open-ended questions of 204 patients with Vitiligo. Construct validity of the resulting instrument was assessed by comparing the instrument's score to the Dermatology Life Quality Index (DLQI), Vitiligo Impact Patient score (VIPs) and Treatment Burden Questionnaire (TBQ) scores. Reliability was assessed by test-retest with 15 ± 10 days of interval between both assessments. RESULTS: In total, 343 adult participants participated in the validation of the Vitiligo Treatment Impact score (VITs). The VITs is a 19-item questionnaire assessing the burden of treatment in patients with vitiligo with results suggesting four domains ('Finding a doctor', 'Phototherapy', 'Topical treatment' and 'Impact on outdoor activities and photoprotection'). The VITs total score was well correlated with the DLQI, VIP and TBQ scores. Agreement between test and retest was good (ICC 0.705, 95% CI 0.491-0.818). CONCLUSIONS: We developed a patient reported measurement of the burden of treatment in vitiligo with good psychometric properties.

RESUMO

BACKGROUND: There are few population-based studies assessing the prevalence of skin diseases. OBJECTIVES: To estimate the prevalence of five chronic skin inflammatory diseases, i.e. atopic dermatitis (AD), psoriasis, alopecia areata (AA), vitiligo and hidradenitis suppurativa (HS) in France, using validated self-diagnostic questionnaires. METHODS: Population-based study using a representative sample of the French general population aged more than 15 years and sampling with replacement design. All participants were asked (ii) to fill in a specific questionnaire including socio-demographic characteristics, (ii) to declare if they have been diagnosed with one or more skin problem or skin diseases during their life, and (iii) to fill in five validated self-reported questionnaires for AD, psoriasis, AA, vitiligo and HS. RESULTS: A total of 20.012 adult participants responded to the questionnaire of whom 9760 were men (48.8%) and 10.252 (51.2%) were women. We identified a prevalence of 4.65% for AD (931 individuals), 4.42% for psoriasis (885 individuals), 1.04% for AA (210 individuals), 0.46% for vitiligo (93 individuals) and 0.15% for HS (29 individuals), respectively. LIMITATIONS: Questionnaire-based study and possible disease misclassifications. CONCLUSION: This is the largest population-based study aiming to estimate the prevalence of five chronic skin inflammatory diseases.
