[Quality of life, disease burden and healthcare need of patients with vitiligo]. / Lebensqualität, Krankheitslast und Versorgungsbedarf von Patienten mit Vitiligo.

BACKGROUND: With a prevalence of 0.5-2%, vitiligo is one of the most common skin disorders worldwide with loss of pigment. The skin disease has a disfiguring, often stigmatising character and is often associated with psychosocial distress. OBJECTIVE: To provide an overview of the psychosocial impairment, disease burden and resulting health care needs of patients with vitiligo. MATERIALS AND METHODS: Narrative review based on a literature search in PubMed for the years 1996-2022 on disease burden, quality of life and stigmatization is provided. RESULTS: The search yielded 175 relevant original papers including clinical studies, meta-analyses and systematic reviews (n = 65) for the search period. A large number of studies document that vitiligo is associated with considerable psychosocial stress and relevant losses in quality of life. Problem areas particularly concern stigmatisation, sexual dysfunction, anxiety, reduced self-esteem and problems at work. The observed increased levels of anxiety and depression correlate with the severity and activity of vitiligo. Often, comorbidity also contributes to reduced self-esteem and social isolation. These factors determine a high need for care in a relevant proportion of those affected. CONCLUSION: Vitiligo is not primarily a cosmetic problem, but a disease requiring treatment according to the World Health Organisation's definition of health as physical, mental and social well-being. The benefits of treatment options are to be measured by their effects on patient-reported outcomes.

Vitiligo patient population and disease burden in France: VIOLIN study results from the CONSTANCES cohort.

BACKGROUND: Vitiligo is a chronic autoimmune disease resulting in skin depigmentation. OBJECTIVES: This study assessed the prevalence, disease burden and treatment of vitiligo in France. METHODS: VIOLIN was a cross-sectional study nested in the national CONSTANCES cohort, which consists of randomly selected adults aged 18-69 years in France. In VIOLIN, longitudinal data were collected prospectively from 158,898 participants during 2012-2018 and linked to the National Health Data System (SNDS), a healthcare utilization database. Patients with physician-diagnosed vitiligo were matched (1:3) with control participants based on age, sex, geographic region, year of inclusion and skin phototype. Patients completed a questionnaire in 2022 to collect disease characteristics, disease burden and quality-of-life (QoL) data. RESULTS: Vitiligo prevalence was 0.71% (681/95,597) in 2018. The mean age in the vitiligo population was 51.2 years; 51.4% were women. Most patients (63%) were diagnosed before age 30 years, mainly by dermatologists (83.5%). Most patients (81.1%) had visible lesions (i.e. on face, hands). Vitiligo was limited to <10% of the body surface area (BSA) in 85.8% of patients. Comorbidities including thyroid disease (18.0% vs. 9.0%), psoriasis (13.7% vs. 9.7%), atopic dermatitis (12.4% vs. 10.3%), depression (18.2% vs. 14.6%) and alopecia areata (4.3% vs. 2.4%) were significantly more common in patients with vitiligo versus matched controls (n = 2043). QoL was significantly impaired in patients with >5% BSA involvement or visible lesions, particularly with ≥10% facial involvement. Vitiligo-specific instruments (i.e. Vitiligo Impact Patient scale and Vitiligo-specific QoL instrument) were more sensitive to QoL differences among subgroups versus general skin instruments, and generic instruments were least sensitive. Most patients (83.8%) did not receive any prescribed treatment. CONCLUSIONS: Patients with vitiligo in France have a high disease burden, particularly those with visible lesions or higher BSA involvement. Most patients are not receiving treatment, highlighting the need for new effective treatments and patient/physician education.

Impact of Vitiligo on Life Quality of Patients: Assessment of Currently Available Tools.

BACKGROUND: How different tools for evaluating health-related quality of life (QoL) reflect the burden of vitiligo has rarely been compared. In this study, we aim to evaluate the impact of vitiligo on QoL using currently available tools. METHODS: A single-center, cross-sectional study of vitiligo patients was performed. QoL was evaluated using the dermatology life quality index (DLQI), short form-36 (SF-36), and willingness to pay (WTP). As the original DLQI cutoff score (>10) indicating aginificantly impated QoL was found to underestimate QoL, receiver operating characteristic (ROC) curve was use to determine a new cutoff point discriminating vitiligo patients with positive mental stress (SF-36 mental health ≤ 52). RESULTS: Of the 143 patients enrolled, 24.5% were identified having significant mental stress by SF-36 mental health domain score ≤ 52 while there were only 13.3% patients with significantly hampered QoL indicated by DLQI >10. Using ROC analysis, DLQI ≥ 7 was found to be a more appropriate DLQI cutoff value for identifying mental stress in vitiligo patients. Additionally, the median WTP for treating vitiligo was comparable to other inflammatory skin diseases. CONCLUSIONS: There exist discrepancies in the outcomes identifying significant disease burden of vitiligo using DLQI and SF-36, making the current DLQI cutoff score (>10) for identifying significantly affected QoL inappropriate for these patients.

Psychosocial Effects of Vitiligo: A Systematic Literature Review.

BACKGROUND: Patients with vitiligo experience reduced quality of life. OBJECTIVE: To comprehensively describe the available evidence for psychosocial burden in vitiligo. METHODS: A systematic review of observational studies and clinical trials identified using PubMed, EMBASE, Scopus, and the Cochrane databases was performed through 1 March, 2021, to assess psychosocial comorbidities in vitiligo. Two independent reviewers performed an assessment of articles and extracted data for qualitative synthesis. RESULTS: Included studies (N = 168) were published between 1979 and 1 March, 2021; 72.6% were published since 2010. Disorders including or related to depression (41 studies, 0.1-62.3%) and anxiety (20 studies, 1.9-67.9%) were the most commonly reported. The most prevalent psychosocial comorbidities were feelings of stigmatization (eight studies, 17.3-100%), adjustment disorders (12 studies, 4-93.9%), sleep disturbance (seven studies, 4.6-89.0%), relationship difficulties including sexual dysfunction (ten studies, 2.0-81.8%), and avoidance or restriction behavior (12.5-76%). The prevalence of most psychosocial comorbidities was significantly higher vs healthy individuals. Factors associated with a significantly higher burden included female sex, visible or genital lesions, age < 30 years (particularly adolescents), and greater body surface area involvement, among others. The most commonly reported patient coping strategy was lesion concealment. LIMITATIONS: Available studies were heterogeneous and often had limited details; additionally, publication bias is possible. CONCLUSIONS: The results of this systematic review show that vitiligo greatly affects psychosocial well-being. The extent of psychosocial comorbidities supports the use of multidisciplinary treatment strategies and education to address the vitiligo-associated burden of disease.

Clinical Features, Immunopathogenesis, and Therapeutic Strategies in Vitiligo.

Vitiligo is an autoimmune disease of the skin characterized by epidermal melanocyte loss resulting in white patches, with an approximate prevalence of 0.5-2% worldwide. Several precipitating factors by chemical exposure and skin injury present commonly in patients with vitiligo. Although the diagnosis appears to be straightforward for the distinct clinical phenotype and specific histological features, vitiligo provides many challenges including chronicity, treatment resistance, frequent relapse, associated profound psychosocial effect, and negative impact on quality of life. Multiple mechanisms are involved in melanocyte disappearance, including genetics, environmental factors, and immune-mediated inflammation. Compelling evidence supports the melanocyte intrinsic abnormalities with poor adaptation to stressors leading to instability and release of danger signals, which will activate dendritic cells, natural killer cells, and innate lymphoid cells to initiate innate immunity, ultimately resulting in T-cell mediated adaptive immune response and melanocyte destruction. Importantly, the cross- talk between keratinocytes, melanocytes, and immune cells, such as interferon (IFN)-γ signaling pathway, builds inflammatory loops that give rise to the disease deterioration. Improved understanding of the immune pathogenesis of vitiligo has led to the development of new therapeutic options including Janus kinase (JAK) inhibitors targeting IFN-γ signaling pathways, which can effectively reverse depigmentation. Furthermore, definition of treatment goals and integration of comorbid diseases into vitiligo management have revolutionized the way vitiligo is treated. In this review, we highlight recent developments in vitiligo clinical aspects and immune pathogenesis. Our key objective is to raise awareness of the complexity of this disease, the potential of prospective therapy strategies, and the need for early and comprehensive management.

The parent and child experience of childhood vitiligo: An interpretative phenomenological analysis.

Vitiligo is a chronic and visible skin condition involving depigmentation with half of those with the condition developing it before the age of 20. This study sought to gain an experiential understanding of the impact of vitiligo on children and their parents. Interpretative phenomenological analysis was used, and semi-structured interviews were conducted with four child-parent dyads (eight participants). Analysis of the participants' accounts revealed four overarching themes (Continuing Burden, The Significance of Visible Difference, Uncertainty and Unpredictability, and Coping), with 12 subthemes. There were some subtle differences between the parents and children. Both parents and child participants described the condition as posing a continuing burden with most participants reporting experiencing unwanted attention and being concerned about future relationship impact. Some parents described experiencing a sense of resignation to the condition, whereas all the children described a greater sense of acceptance. Nevertheless, acceptance seemed fragile, and parents were concerned that their children needed assistance in developing self-confidence. The findings represent the first in-depth analysis of childhood vitiligo.

The relationship between stress and vitiligo: Evaluating perceived stress and electronic medical record data.

Vitiligo is a T-cell mediated skin disorder characterized by progressive loss of skin color. In individuals genetically predisposed to the disease, various triggers contribute to the initiation of vitiligo. Precipitating factors can stress the skin, leading to T-cell activation and recruitment. Though hereditary factors are implicated in the pathogenesis of vitiligo, it is unknown whether precipitating, stressful events play a role in vitiligo. To understand this, we utilized a validated perceived stress scale (PSS) to measure this parameter in vitiligo patients compared to persons without vitiligo. Additionally, we probed a clinical database, using a knowledge linking software called ROCKET, to gauge stress-related conditions in the vitiligo patient population. From a pool of patients in an existing database, a hundred individuals with vitiligo and twenty-five age- and sex-matched comparison group of individuals without vitiligo completed an online survey to quantify their levels of perceived stress. In parallel, patients described specifics of their disease condition, including the affected body sites, the extent, duration and activity of their vitiligo. Perceived stress was significantly higher among vitiligo individuals compared to those without vitiligo. ROCKET analyses suggested signs of metabolic-related disease (i.e., 'stress') preceding vitiligo development. No correlation was found between perceived stress and the stage or the extent of disease, suggesting that elevated stress may not be a consequence of pigment loss alone. The data provide further support for stress as a precipitating factor in vitiligo development.

Identifying key components for a psychological intervention for people with vitiligo - a quantitative and qualitative study in the United Kingdom using web-based questionnaires of people with vitiligo and healthcare professionals.

BACKGROUND: Psychological interventions are recommended as part of routine management of vitiligo. However, the development and effectiveness of such interventions have been rarely addressed. This study aimed to identify key components for a psychological intervention for people with vitiligo. This is the first time perspectives of people with vitiligo, and healthcare professionals (HCPs) have been directly explored to inform intervention content and delivery. OBJECTIVES: To identify 1. which psychological difficulties are highlighted that can be targeted by an intervention; 2. what is important in terms of intervention content and delivery. METHODS: Web-based questionnaires containing both quantitative and qualitative items were completed by people with vitiligo and HCPs. Questionnaires collected data from people with vitiligo on demographics, clinical features, psychological difficulties and priority areas for psychological interventions, including ideas on delivery and content. HCPs questionnaires collected data on psychological difficulties reported, use of psychological interventions and suitability within health services. Quantitative data were analysed using descriptive statistics, and qualitative data utilized thematic framework analysis. RESULTS: A total of 100 people with vitiligo (66% female, 92% Caucasian) and 39 HCPs (54% dermatologists) participated. Key areas of difficulty were the impact of vitiligo, coping, issues with appearance/body image and the sun, and medical interactions. Vitiligo on sensitive sites was associated with more psychological impact. Interventions directed at increasing acceptance, confidence and self-esteem, as well as managing embarrassment, were important. These issues could be managed through interventions such as cognitive behavioural therapy, mindfulness and acceptance and commitment therapy. Both people with vitiligo and HCPs favoured individual interventions. CONCLUSION: Vitiligo has significant impact, requiring ongoing psychosocial support. There is a strong need for a psychoeducational intervention with focus on acceptance and managing social impact. The results of this study are the first steps to informing the development of a patient-centred psychological intervention.

Quality of Life, Burden of Disease, Co-morbidities, and Systemic Effects in Vitiligo Patients.

Vitiligo is a complex, systemic disease associated with many autoimmune and autoinflammatory conditions. Additionally, the cutaneous changes of vitiligo have significant effects on quality of life and self-esteem. Further efforts are needed to increase our understanding of vitiligo comorbidities as well as to increase awareness of the psychological effects of vitiligo.

Hidden victims of childhood vitiligo: impact on parents' mental health and quality of life.

This study aims to assess the impact of childhood vitiligo on the psychological status and quality of life of their parents, and to determine how this varies according to their children's disease condition. The study included 50 families of children with vitiligo (a total of 75 participants) and 50 families of normal children (a total of 79 participants). The psychosocial impact of the disease on parents was measured using the Self-rated Health Measurement Scale (SRHMS) and the Dermatitis Family Impact Questionnaire (DFI). SRHMS scores for parents of children with vitiligo were significantly lower than for parents with normal children. In addition, women had lower scores than men in the study group. The mean DFI score in affected families was higher than in unaffected families. Parents of children with vitiligo have significant psychological problems, and their quality of life is poorer than for parents of normal children. In conclusion, parents of children with vitiligo need as much care and attention as their affected children.

Stigmatisation, Avoidance Behaviour and Difficulties in Coping are Common Among Adult Patients with Vitiligo.

Vitiligo is a non-contagious skin disorder with loss of pigmentation, often impairing patients' well-being. This study used Dermatology Life Quality Index (DLQI), Adjustment to Chronic Skin Disorders Questionnaire (ACS), Beck Depression Inventory (BDI) and additional questions to explore quality of life (QoL), coping, depression and stigmatisation and included 96 patients with vitiligo and 23 controls. Stigmatisation was common: 87/96 patients (90%) reported questions/approaches, 23/96 (24%) experienced nasty comments. Sixty-four out of 96 (66.7%) had avoided situations because of vitiligo or concealed their white spots. Sixty patients (62.5%) implied psychological stress as influential on disease's course. Patients scored higher in all questionnaires than controls (DLQI = 4.9/1.6, ACS-social anxiety/avoidance = 36.9/22.1, ACS-helplessness = 27.3/16.0, ACS-anxious-depressive mood = 19.4/15.6), except BDI (6.8/7.3). QoL of 65 patients (67.7%) was hardly impaired, 70 (72.9%) were not depressed. Treatment with pro-pseudocatalase PC-KUS reduced social anxiety/avoidance, anxious-depressive mood and depression. Patients without low-key stigmatisation scored highest in DLQI and social anxiety/avoidance. Avoidance and concealing behavior correlated with all questionnaires' scores.

Perfil clínico e epidemiológico do vitiligo infantil: análise de 113 casos diagnosticados em um centro de referência em dermatologia de 2004 a 2014 / Clinical and epidemiological profile of childhood vitiligo: analysis of 113 cases diagnosed at a dermatology referral center from 2004 to 2014

Introdução: O vitiligo é forma adquirida autoimune de hipopigmentação ou despigmentação, iniciando-se na infância metade de seus casos. Objetivos: Traçar o perfil clínico e epidemiológico do vitiligo infantil em um centro de referência em dermatologia. Métodos: Estudo transversal e descritivo com análise dos prontuários de pacientes com menos de 13 anos diagnosticados como portadores de vitiligo entre 2004 e 2014. Resultados: Dos 113 casos identificados, 54% eram do sexo feminino e 46% do sexo masculino; a idade variou de zero a 12 anos com a maioria dos pacientes (54,8%) no subgrupo de quatro a oito anos. Em 59% dos prontuários não havia registro sobre fatores desencadeantes do vitiligo; 31% dos pacientes associaram o início da doença a estresse emocional, 3% a trauma físico, e 7% não associaram a fator desencadeante. Conclusões: A discreta prevalência no sexo feminino também foi descrita em outros estudos. O comportamento do vitiligo na criança é diferente daquele observado nos adultos. A influência dos fatores psicológicos como desencadeantes e os potenciais efeitos duradouros na autoestima devem ser levados em consideração na abordagem do paciente. Os resultados deste trabalho foram semelhantes aos relatos existentes sobre o vitiligo nessa faixa etária, que são, aliás, poucos na literatura

Introduction: Vitiligo is an acquired autoimmune form of hypopigmentation or depigmentation in which half of the cases begins in childhood. Objectives: To describe the clinical and epidemiological profile of childhood vitiligo in a referral center for dermatology. Methods: A cross-sectional, descriptive study was carried out based on the analysis of medical records of patients younger than 13 years diagnosed with vitiligo from 2004 to 2014. Results: Of the 113 cases identified, 54% were female and 46% male, the age ranged from 0 to 12 years, with most patients in the 4-8 years-old subgroup (54.8%). In 59% of the medical records there was no record of triggering factors of vitiligo; 31% of patients associated the onset of the illness to emotional stress, 3% to physical trauma and 7% did not associate it to any triggering factor. Conclusions: The discreet prevalence in women has also been reported in other studies. Vitiligo behavior in children is different from that observed in adults. The influence of psychological factors as triggers and potential lasting effects on self-esteem should be considered in the approach of the patient. Although studies on vitiligo in this age group are scarce in the literature, the results of the present study were similar to the reports already available in the literature

To what extent is quality of life impaired in vitiligo? A multicenter study on Italian patients using the dermatology life quality index.

BACKGROUND: It is believed that vitiligo has an impact on the overall patient quality of life (QoL). OBJECTIVE: To estimate QoL in a fairly large sample of Italian vitiligo patients by using the Dermatology Life Quality Index (DLQI) questionnaire. METHODS: One hundred and sixty-one vitiligo patients referred to 9 dermatological centers were offered to participate by filling in the Italian version of the DLQI questionnaire. RESULTS: The mean total DLQI score was 4.3 (SD ±4.9; range: 0-22). In multivariate analysis, DLQI >5 was associated with female gender, stability of the disease over time and involvement of the face at disease onset. CONCLUSIONS: The impairment of QoL is overall limited in Italian vitiligo patients, especially if it is compared with results from other available studies. This could be due to cultural and ethnic characteristics of the sample.

Effect of age at onset on disease characteristics in vitiligo.

BACKGROUND: Vitiligo is a multifactorial disease in which genetic, immunologic, and environmental factors play an important part. Late-onset vitiligo is a poorly defined entity. MATERIALS AND METHODS: Case records of patients who attended the pigmentary clinic at our institute from January 2001 to December 2010 were reviewed. Patients with a diagnosis of vitiligo were analyzed with respect to their demographic characteristics with special reference to their age at onset. RESULTS: Patients with disease onset after 30 years had a significantly higher association with precipitating factors such as trauma, stress, and drugs in comparison with early-onset vitiligo (p < .004). However, the difference did not reach statistical significance when these factors were analyzed individually. There was a significantly higher association with other nonautoimmune diseases (p  =  .05), a higher incidence of positive family history (p < .0001), and a higher association with leukotrichia (p < .002) in late-onset disease. Early-onset nonsegmental vitiligo was associated with a higher incidence of photosensitivity and pruritus compared to early-onset segmental vitiligo. CONCLUSION: Late-onset vitiligo has certain distinguishing features compared to early-onset vitiligo.
