BACKGROUND Vitiligo is considered the most frequent acquired hypomelanosis. Although its pathogenesis is uncertain, it is believed that autoimmune etiology is the most plausible. This theory is based on the coexistence of vitiligo with autoimmune diseases. OBJECTIVES To describe the epidemiological profile of vitiligo patients and to estimate the prevalence of the association of vitiligo with...

BACKGROUND Vitiligo is a chronic, common disease of unknown etiology, and oxidative stress is suggested to have a role in its etiopathogenesis. OBJECTIVE Advanced oxidation protein products (AOPPs), prooxidant-antioxidant balance (PAB), and ferric-reducing antioxidant power (FRAP) were evaluated regarding their role in the pathogenesis of vitiligo as well as their relationship with clinical p...

Vitiligo is an acquired depigmentary skin disorder characterized by white maculae on the skin associated with social stigma. Vitiligo has major impact on the quality of life due its high cosmetic value, chronic nature of disease and long term ineffective treatments. Vitiligo patients suffer from low self-esteem and poor body image that affects their emotional and psychological well-being. To in...

Vitiligo is an autoimmune skin disorder clinically characterized by depigmented patches. With therapeutically challenging, a deeper understanding of its pathomechanisms needed to improve current therapeutic approaches. Granzyme B (GzmB), serine protease, has been identified in abundance vitiligo lesions, and genetic polymorphisms GZMB have reported multiple patients. It initially discovered gra...

INTRODUCTION Vitiligo is an acquired idiopathic depigmentary disorder, which, though worldwide in distribution, is very common in India, Egypt and other tropical countries. While patients become desperate, develop a complex and social ostracism, a conscientious physician feels guilty because of his limitations. Though various aspects of vitiligo have been extensively studied, its etiopathogenes...

Vitiligo is an acquired skin disorder characterized by patchy depigmentation of the skin [1]. Vitiligo affects approximately 0.5% to 2% of the population worldwide, and the prevalence appears to be equal between men and women [2,3]. The pathogenesis of vitiligo is still not fully understood and mounting evidences have suggested that it might be related to autoimmunity and oxidative stress [4]. ...

Vitiligo is a complex genetic skin depigmentation disorder caused by the destruction of melanocyte from the lesional site. Liver X Receptor-α (LXR-α) expression is upregulated in the melanocytes from perilesional skin as compared to the normal skin of vitiligo patient suggesting its involvement in vitiligo pathogenesis. Polymorphisms in LXR-α have been associated with several diseases including...

BACKGROUND It was previously thought that persons with genetic predispositions to vitiligo develop the condition after exposure to various precipitating environmental factors. However, in many cases, the aggravating factors of vitiligo have not been clearly identified. OBJECTIVE To identify the aggravating factors of vitiligo in the working environment and daily life. METHODS A total of 489...

Background: Vitiligo is a common depigmentary disorder characterized by white patches of the skin, hair and mucous membranes due to selective destruction of melanocytes. Objective: The objective of this study was to analyze the clinical characteristics, coexisting diseases, presence of autoantibodies and autoimmune polyglandular syndrome (APS) in Estonian adult vitiligo patients. Methods:Adult ...

Most patients with active vitiligo (82% of 61) have antibodies to antigens of normal human melanocytes that can be detected by specific immunoprecipitation of radioiodinated, detergent-soluble, melanocyte macromolecules. Such antibodies were present in only 12% of patients with melanoma and in none of 35 patients with nonpigmentary skin diseases. The antibodies were directed to a common antigen...
