This study assessed the prevalence, disease burden, and treatment of vitiligo in France. The results showed that the prevalence of vitiligo in France was 0.71%, most patients were diagnosed before the age of 30, and had visible skin lesions. Vitiligo patients had a high burden of comorbidities and impaired quality of life, but the majority of patients did not receive any prescribed treatment.
Background: Vitiligo is a chronic autoimmune disease resulting in skin depigmentation.Objectives: This study assessed the prevalence, disease burden and treatment of vitiligo in France.Methods: VIOLIN was a cross-sectional study nested in the national CONSTANCES cohort, which consists of randomly selected adults aged 18-69 years in France. In VIOLIN, longitudinal data were collected prospectively from 158,898 participants during 2012-2018 and linked to the National Health Data System (SNDS), a healthcare utilization database. Patients with physician-diagnosed vitiligo were matched (1:3) with control participants based on age, sex, geographic region, year of inclusion and skin phototype. Patients completed a questionnaire in 2022 to collect disease characteristics, disease burden and quality-of-life (QoL) data.Results: Vitiligo prevalence was 0.71% (681/95,597) in 2018. The mean age in the vitiligo population was 51.2 years; 51.4% were women. Most patients (63%) were diagnosed before age 30 years, mainly by dermatologists (83.5%). Most patients (81.1%) had visible lesions (i.e. on face, hands). Vitiligo was limited to <10% of the body surface area (BSA) in 85.8% of patients. Comorbidities including thyroid disease (18.0% vs. 9.0%), psoriasis (13.7% vs. 9.7%), atopic dermatitis (12.4% vs. 10.3%), depression (18.2% vs. 14.6%) and alopecia areata (4.3% vs. 2.4%) were significantly more common in patients with vitiligo versus matched controls (n = 2043). QoL was significantly impaired in patients with >5% BSA involvement or visible lesions, particularly with = 10% facial involvement. Vitiligo-specific instruments (i.e. Vitiligo Impact Patient scale and Vitiligo-specific QoL instrument) were more sensitive to QoL differences among subgroups versus general skin instruments, and generic instruments were least sensitive. Most patients (83.8%) did not receive any prescribed treatment.Conclusions: Patients with vitiligo in France have a high disease burden, particularly those with visible lesions or higher BSA involvement. Most patients are not receiving treatment, highlighting the need for new effective treatments and patient/physician education.
