Vitiligo is a depigmenting disorder characterized by the development of white patches in various distributions, which are due to the loss of melanocytes from the epidermis. A variety of arguments from clinical observations to research findings in human and animal models support the hypothesis of autoimmunity and are reviewed in this article. The association with autoimmune diseases and organ-specific autoantibodies is well known. Various effective treatment options have an immunosuppressive effect. Today the autoimmune pathogenesis of the disease has become a rapidly evolving field of research.Detection of circulating melanocyte antibodies in human and animal models implicates a possible role of humoral immunity. Histological and immunohistochemical studies in perilesional skin suggest the involvement of cellular immunity in vitiligo. Recently, T-cell analyses in peripheral blood further support this hypothesis. Interestingly, new insights in the association of vitiligo and melanoma may help to clarify the role of autoimmunity in the development of vitiligo.
Our study quantifies the burden on the quality of life caused by vitiligo and indicates specific areas of patients' lives which are most affected by the disease. Sex, number of consultations and subjective disease severity independently predict the quality of life. The quality of life impairment in women affected with vitiligo equals the impairment caused by psoriasis in our study population. These results should awake the interest of physicians in this 'cosmetic' disease, since appropriate treatment is likely to improve the quality of life of vitiligo patients.
Background: Few studies have paid attention to the effects of treatment interventions on the psychosocial consequences of vitiligo. Objectives: To quantify and analyse the psychosocial benefit of the use of camouflage in vitiligo patients. Patients and Methods: 78 vitiligo patients completed the Dermatology Life Quality Index (DLQI) and an adapted stigmatization questionnaire, and 62 of them completed the DLQI after at least a 1-month use of camouflage. Results: The initial mean overall DLQI score (n = 78) is 6.9 (SD 5.6). The mean global stigmatization score is 38%. Disease extent and disease severity are strong predictors of the DLQI (p < 0.0001). Vitiligo on the face/head/neck substantially affects the DLQI, independently of degree of involvement. The mean DLQI score before and after use of camouflage (n = 62) is 7.3 (SD 5.6) and 5.9 (SD 5.2; p = 0.006). Mainly the high-scoring items ‘feelings of embarrassment and self consciousness’ and ‘choice of clothing’ improve. Predictors of improvement are higher DLQI scores (p = 0.0005) and higher total severity scores (p = 0.03). Conclusions: Camouflage can be recommended, particularly in patients with higher DLQI scores or self-assessed disease severity. Patients with minor involvement of the face benefit from camouflage.
A limited number of studies have paid attention to the psychosocial well-being of patients affected with vitiligo. We review the psychosocial effects of vitiligo, how patients deal with them and the psychiatric morbidity in vitiligo patients. Given the appreciable comorbidity, it is important to consider these observations in the management of patients, for example in patient-physician interaction but also in treatment strategies and evaluation of treatments. The effects of the psychological state on the disease itself together with the potential therapeutic implications are reviewed. Based on these data, we suggest how to further improve patient's management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
