Nonsegmental vitiligo disease duration and female sex are associated with comorbidity and disease extent: a retrospective analysis in 1307 patients aged ≥ 50 years.

The disease course of nonsegmental vitiligo is relatively unstudied. Clinical and epidemiological differences have been described in early- versus later-onset vitiligo but duration of disease has not been taken into account. Also, the prevalence of auto-immune comorbidities in patients with vitiligo has been mostly studied in young vitiligo patient populations while autoimmune comorbidity may manifest later in life. The aim of this study was to retrospectively assess factors associated with disease extent and the life-time prevalence of autoimmune comorbidities in a large cohort of older-aged patients with nonsegmental vitiligo.
