Impact of Vitiligo on Quality of Life.

INTRODUCTION AND

OBJECTIVE

Vitiligo is a chronic autoimmune skin disease caused by the destruction of melanocytes. Although quality of life (QOL) in vitiligo has been studied in different countries, it has not yet been investigated in Mexico. The aim of this study was to assess the QOL of Mexican patients with vitiligo.

MATERIAL AND METHOD: We conducted a cross-sectional study at the research unit of Centro Dermatológico Dr. Ladislao de la Pascua in Mexico City. We included adults with vitiligo and excluded those with other pigmentation disorders or a neurological or psychiatric disorder. Patients on psychoactive medications were also excluded. All the patients were administered the Dermatology Life Quality Index (DLQI), a vitiligo-specific quality of life instrument (the VitiQoL), and the Beck Depression and Anxiety Inventories.

RESULTS

We studied 150 patients with vitiligo (103 women [68.7%] and 47 men [31.3%]). The median (interquartile range) age was 38 (20) years. The mean (SD) scores on the DLQI and VitiQoL were 5.2 (5.4) and 32.1 (22.7) out of total possible scores of 30 and 90, respectively. The correlation between questionnaire scores was 0.675 (P<.001). Patients with genital involvement scored significantly worse on the VitiQoL than those without lesions in this area (43.95 [28.4]) vs. 28.98 [20.08], P<.001). The prevalence of depression and anxiety was 34% and 60%, respectively.

CONCLUSION

Vitiligo has a minimal impact on the QOL of our patients. QOL was worse in patients with genital lesions.
