“…On the other hand, an estimate of the prevalence of vitiligo in the black population in the French West Indies concluded that it is comparable to or slightly less than the currently accepted data for white people . Finally, in a recent population‐based study conducted using telephone interviews in selected cities of Brazil, the prevalence of physician‐diagnosed vitiligo varies from 0.46% to 0.68% across Brazil . The disparity between prevalence data and incidence figures may be due to a higher reporting of vitiligo in highly pigmented skins in which lesions are more prominent.…”

“…Epidemiology. Vitiligo is the most common depigmenting disorder, with a global prevalence of ~0.06-8.8%, according to data published between 1964 and 2017 (31)(32)(33)(34)(35). Vitiligo affects men and women equally (33).…”

Novel immunological and genetic factors associated with vitiligo: A review

et al. 2021

Vitiligo is a skin disorder characterized by depigmentation of the skin due to a lack of melanin. This condition affects men and woman of all ages and its incidence is not restricted by ethnicity or region. Vitiligo is a multifactorial disease, in which melanocytes, which serve important functions in skin pigmentation and immune processes, are impaired. There is sufficient evidence that immunological and genetic factors are primarily responsible for the destruction and dysfunction of melanocytes. Therefore, genetic DNA sequence variants that participate in skin homeostasis, pigmentation and immune response regulation, as well as altered expression patterns, may contribute to the risk of developing vitiligo. The current review presented an overview of the mechanism of pigmentation and of currently known factors involved in depigmentation, as well as the classification, epidemiology, associated comorbidities, risk factors, immunopathogenesis and several genetic and molecular changes associated with vitiligo. Contents 1. Overview 2. Immunopathogenesis of vitiligo 3. Genetic factors associated with vitiligo 4. Conclusions

Vitiligo is a common chronic autoimmune disorder characterized by skin and hair depigmentation that affects 0.5%–2.0% of the global population. Vitiligo is associated with diminished quality of life (QoL) and psychosocial burden. The burden of vitiligo may vary based on skin tone and cultural differences as well as geographical variations in disease awareness, societal stigma, healthcare systems and treatment options. Data on the burden and management of vitiligo in Africa, the Middle East and Latin America are scarce. Literature searches using terms covering vitiligo in Africa, the Middle East and Latin America were conducted using PubMed to identify relevant publications that focused on disease prevalence and burden, QoL and psychosocial impact and disease management between 2011 and 2021. Most of the reviewed studies were conducted in the Middle East, and most Latin American studies were from Brazil. Most studies involved small patient numbers and may not be generalizable. Reported prevalence of vitiligo ranged from 0.18% to 5.3% in Africa and the Middle East, and from 0.04% to 0.57% in Latin America. In several studies, prevalence was higher among female participants. Generally, non‐segmental vitiligo was the dominant clinical variant identified and the age at onset varied widely across studies. Common comorbidities include autoimmune diseases such as Hashimoto's thyroiditis, alopecia areata and diabetes. Few treatment guidelines exist in these regions, with the exceptions of guidelines published by the Brazilian and Argentinian Societies of Dermatology. There is a clear unmet need for large epidemiological studies with uniform methodology to accurately ascertain the true prevalence of vitiligo in Africa, the Middle East and Latin America. Additional data on vitiligo burden and management in Africa and Latin America are also needed, along with local disease management guidelines that consider genetic variation, psychosocial burden and socioeconomic diversity in all 3 regions.
