Clinico-Epidemiological Profile and Treatment Pattern of Vitiligo in Selected Dermatological Clinics of Mekelle City, Northern Ethiopia

Abstract

Background. Vitiligo is not a well-studied disease in Ethiopia. Therefore, this study assessed its clinico-epidemiological profile and treatment patterns. Methods. An institutional-based cross-sectional study was conducted in conveniently selected dermatologic clinics of Mekelle city, Ethiopia. A two-phased study was conducted, in which the first was to determine prevalence of vitiligo while the second phase was to describe the clinico-epidemiological profile and treatment pattern of vitiligo. Four-hundred three randomly selected dermatological patients were included in the first phase study. The second phase study included vitiligo cases from the first phase study and additional vitiligo cases found in a two months period prospective study. Results. Of the 403 randomly selected dermatological patients who presented in the year 2017 to 2019, the prevalence of vitiligo was 13.15%. Of the 79 cases with vitiligo, nearly two-thirds (50, 63.3%) were males with five years as the median age at onset of the disease. Positive family history of vitiligo was recorded in about one-third (25, 31.6%) of the cases. Limbs (48, 44.5%) followed by the head and neck (26, 24%) were the most commonly affected parts of the body at the onset of the disease. The most prevalent clinical form of vitiligo was vulgaris (39.2%) followed by the focal type (26.6%). Emotional upset (24, 33.8%) and physical traumas (23, 32.4%) were the frequently reported triggering factors of vitiligo. Three-fourths (75.5%) of the cases had prescriptions of topical corticosteroids, and 24.5% of them had prescriptions of sun screen lotion. Conclusion. The prevalence of vitiligo was found to be high. The clinico-epidemiological profile of vitiligo in Ethiopia was similar with that found globally. However, treatment options of vitiligo were very limited in Ethiopia.
