Abstract
Background and Aims Vitiligo, an acquired sometimes familial depigmentary disorder of the skin and hair that results from selective destruction of melanocytes or pigment cells. It is the single most important non-neo plastic disease that involves both the immune system and melanocytes which are subsequently destroyed and the affected area turns pale and becomes white. The prevalence of the disease is between 1% and 2% in general population. Methods It is a prospective, randomized, and controlled study. Over 90 vitiligo patients attending Dermatology OPD and vitiligo clinic are enrolled in the study. About 35 apparently healthy, age and sex matched individuals are selected to serve as control. A prescribed proforma containing all the demographic data, relevant questionnaire were recorded for each and every case with brief clinical history suggestive of any thyroid disease as well as those referred by the clinicians. P value <0.05 is considered significant. The Quantitative Determination of Thyroglobulin (Tg) Autoantibodies in Human Serum or Plasma by a Microplate Enzyme Immunoassay. Results Vitiligo group, thirty four (37.78%) patients have clinical hypothyroidism while 9 (10%) patients have clinical hyperthyroidism. This difference in the distribution is statistically significant (P < 0.05) with a Chi-square value of 10.08. The data are entered, analyzed and computed with SPSS version 15 software and well-known statistical test like Chi-square, students' 't' test have been advocated wherever found applicable. P value <0.05 is considered significant. Conclusion There is increased incidence of autoimmune thyroid diseases among vitiligo patients. The reason being vitiligo usually precedes the onset of thyroid dysfunction.

Abstract
BACKGROUND This study aimed to develop an autoimmune thyroid disease (AITD) risk prediction model for patients with vitiligo based on readily available characteristics. METHODS A retrospective analysis was conducted on the clinical characteristics, demographics, skin lesions, and laboratory test results of patients with vitiligo. To develop a model to predict the risk of AITD, the Least Absolute Shrinkage and Selection Operator (LASSO) method was used to optimize feature selection, and logistic regression analysis was used to select further features. The C-index, Hosmer-Lemeshow test, and decision curve analysis were used to evaluate the calibration, discrimination ability and clinical utility of the model. Internally, the model was verified using bootstrapping; externally, two independent cohorts were used to confirm model accuracy. RESULTS Sex, vitiligo type, family history of AITD, family history of other autoimmune disease, thyroid nodules or tumors, negative emotions, skin involvement exceeding 5% of body surface area, and positive immune serology (IgA, IgG, IgM, C3, and C4) were predictors of AITD in the prediction nomogram. The model showed good calibration and discrimination (C-index: 0.746; 95% confidence interval: 0.701-0.792). The accuracy of this predictive model was 74.6%.In both internal validation (a C-index of 1000 times) and external validation, the C-index outperformed (0.732, 0.869, and 0.777). The decision curve showed that the AITD nomogram had a good guiding role in clinical practice. CONCLUSION The novel AITD nomogram effectively evaluated the risk of AITD in patients with vitiligo.

Abstract
OBJECTIVE Vitiligo is a common dermatological disease of unknown cause and progressing with depigmentation and affects approximately 1% of the world population. In the study, we aimed to compare plateletcrit (PCT), mean platelet volume (MPV), platelet (PLT), and thyroid-stimulating hormone (TSH) values in vitiligo patients. MATERIAL AND METHODS We retrospectively evaluated the medical data of 100 patients who were admitted to the dermatology outpatient clinic between January 2020 and December 2021 with a diagnosis of vitiligo. The control group was retrospectively constituted from medical records of 190 healthy individuals. PCT, MPV, PLT, and TSH levels of both groups were compared statistically. RESULTS A total of 190 participants (100 vitiligo patients and 90 healthy volunteers) were included in the study. The mean age of the patient group was 38.62±1.62, while the mean age of the control group was 41.52±1.54. There were no differences between the two groups in terms of age and gender. It was found that the mean MPV value in the patient group was lower than the control group (p=0.00). PLT and PCT values were significantly higher in the patient group than the control group (p=0.00, p=0.01, respectively). There was no statistically significant difference between the two groups in terms of TSH (p>0.05). A negative correlation between MPV and PLT values in the patient group (r=-0.218, p=0.029), and a negative correlation between MPV and TSH (r=-0.218, p=0.029). -0.230, p=0.021). CONCLUSION In the study, a comparison of the PCT, MPV, and PLT levels showed a difference between both groups, but no differences in TSH levels. To clarify these results, comprehensive studies with more samples are needed.

Abstract
Among disorders of pigmentation, vitiligo is the most common, with an estimated prevalence between 0.5% and 1%. The disease has gathered increased attention in the most recent years, leading to a better understanding of the disease’s pathophysiology and its implications and to the development of newer therapeutic strategies. A better, more integrated approach is already in use for other chronic inflammatory dermatological diseases such as psoriasis, for which metabolic comorbidities are well-established and part of the routine clinical evaluation. The pathogenesis of these might be linked to cytokines which also play a role in vitiligo pathogenesis, such as IL-1, IL-6, TNF-α, and possibly IL-17. Following the reports of intrinsic metabolic alterations reported by our group, in this brief review, we analyze the available data on metabolic comorbidities in vitiligo, accompanied by our single-center experience. Increased awareness of the metabolic aspects of vitiligo is crucial to improving patient care.

Abstract
BACKGROUND Vitiligo is a relatively common acquired pigmentation disorder that can cause significant psychological stress and stigmatism. OBJECTIVE This article aims to familiarize physicians with the clinical manifestations, evaluation, diagnosis, and management of vitiligo. METHODS A Pubmed search was conducted in Clinical Queries using the key term "vitiligo". The search included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to English language. The information retrieved from the above search was used in the compilation of the present article. RESULTS Approximately one quarter of patients with vitiligo have the onset before 10 years of age. Genetic, immunological, neurogenic and environmental factors may have a role to play in the pathogenesis. Vitiligo typically presents as acquired depigmented, well-demarcated macules/patches that appear milk- or chalk-white in color. Lesions tend to increase in number and enlarge centrifugally in size with time. Sites of predilection include the face, followed by the neck, lower limbs, trunk, and upper limbs. The clinical course is generally unpredictable. In children with fair skin, no active treatment is usually necessary other than the use of sunscreens and camouflage cosmetics. If treatment is preferred for cosmesis, topical corticosteroids, topical calcineurin inhibitors, and narrowband ultraviolet B phototherapy are the mainstays of treatment. CONCLUSION The therapeutic effect of all the treatment modalities varies considerably from individual to individual. As such, treatment must be individualized. In general, the best treatment response is seen in younger patients, recent disease onset, darker skin types, and head and neck lesions. Topical corticosteroids and calcineurin inhibitors are the treatment choice for those with localized disease. Topical calcineurin inhibitors are generally preferred for lesions on genitalia, intertriginous areas, face, and neck. Narrowband ultraviolet B phototherapy should be considered in patients who have widespread vitiligo or those with localized vitiligo associated with a significant impact on the quality of life who do not respond to treatment with topical corticosteroids and calcineurin inhibitors.

Abstract
Vitiligo is a common polygenic autoimmune disease in which the foci of depigmentation are formed on the skin and/or mucous membranes as a result of the death of melanocytes. There are several hypotheses for the pathogenesis of the disease, the leading role among them is played the autoimmune hypothesis. This review summarizes the available literature data on the prevalence and structure of comorbid endocrine autoimmune pathology in vitiligo patients. In most studies conducted in Europe, America and Asia the prevalence of autoimmune thyroid diseases (including autoimmune thyroiditis and Graves disease), diabetes mellitus and autoimmune adrenal insufficiency was higher in vitiligo patients than in the general population. The results of some studies indicate a frequent association of vitiligo with autoimmune polyglandular syndromes. In the structure of comorbid pathology the highest prevalence was in autoimmune thyroid diseases. A number of studies have established a higher prevalence of autoimmune endocrine diseases in women, as well as in nonsegmental vitiligo patients and in cases of family history of vitiligo and/or other autoimmune diseases. In addition, it was shown that the prevalence of endocrine diseases increases with increasing area of depigmentation. The data obtained justify the advisability of conducting a timely examination of vitiligo patients with the aim of early detection of comorbid diseases and the appointment of appropriate treatment. Further studies are needed to investigate the effect of the identified associations on the course of vitiligo and comorbid endocrinopathies, as well as the effectiveness of therapy and the quality of life of patients.

Abstract
Vitiligo is a complex disease in which autoimmune destruction of epidermal melanocytes results in patches of depigmented white skin. Vitiligo has an estimated prevalence of about 0.2-2% in different populations and approximately 0.4% in the European-derived white (EUR) population. The fraction of disease risk attributable to genetic variation, termed heritability, is high, with estimates from family studies in EUR of 0.75-0.83 and from SNP based studies estimated at 0.78. About 70% of genetic risk comes from common genetic variants and about 30% from rare genetic variants. Through candidate gene, genomewide linkage, and genomewide association studies, over 50 vitiligo susceptibility loci have been discovered. These have been combined into a vitiligo polygenic risk score, which has allowed various aspects of vitiligo genetic architecture in the EUR population to be better understood. Vitiligo has thus proved to be a particularly tractable model for investigation of complex disease genetic architecture. Here, we summarize progress to date including dissection of heritability, discovery of vitiligo susceptibility loci through candidate gene, genomewide linkage, and genomewide association studies, relationships to other autoimmune diseases, polygenic architecture of vitiligo risk, vitiligo triggering, and disease onset, and provide suggestions for future directions.

Abstract
BACKGROUND Vitiligo is an acquired pigmentary disorder that affects approximately 0.5-2% of the world's population, and 25% of cases begin before 10 years of age. Although prevalent, there are few studies on the characterization of childhood vitiligo. OBJECTIVE To evaluate the clinical and epidemiological characteristics of childhood vitiligo. METHODS Transverse study conducted by reviewing data records of patients under the age of 18 in which disease onset occurred before 13 years of age. RESULTS Predominance of females (62%). The most common subtype was generalized vitiligo (53.8%). The average age of disease onset was 5.9 years. The most affected initial site was head/neck (44.22%). The Koebner phenomenon was present in 38.2%, emotional triggering factors in 67.0% of the patients, halo nevus in 17.4%, and associated autoimmune disease in 6.5% of the patients. Family history of vitiligo was observed in 16.9% of the patients, and stability was reported by 20.1% of patients. The presence of positive family history did not significantly influence the age of onset. We found a significant difference between segmental vitiligo (SV) and nonsegmental vitiligo (NSV) regarding the age of onset, Koebner phenomenon, hypothyroidism, anti-TPO antibodies, family history of psoriasis, and halo nevus. CONCLUSION Childhood vitiligo has its own characteristics. Vitiligo different subtypes have distinct characteristics. Our study presents a great number of patients, helping to elucidate the peculiarities of childhood vitiligo in the Brazilian population.

Abstract
Vitiligo is a common acquired depigmenting skin disease characterized by a progressive loss of functional melanocytes. It may appear from the first years of life to late adulthood. Childhood vitiligo (CV), defined as vitiligo that begins before the age of 12 years, is common and may differ from post-CV in terms of epidemiology, clinical presentation, comorbidities, and treatment options. Taking into consideration the potential significant psychosocial impact of the disease on both children and their parents, all available therapeutic options must be offered to patients who desire treatment. According to the most recent guidelines, topical corticosteroids, topical calcineurin inhibitors, and narrowband ultraviolet B phototherapy are the most commonly used treatment modalities for vitiligo in children. This review presents recent data regarding the whole spectrum of CV. Differences between CV and post-CV are also discussed.

Abstract
Vitiligo is a common acquired depigmenting disorder characterized by the development of white macules and patches due to the loss of melanocytes. Patients with vitiligo can be stigmatized by society, making the disease a source of psychological stress that can considerably affect quality of life. The goal of vitiligo treatment is to obtain skin repigmentation in the majority of cases, and less commonly to depigment the remaining normal skin. There is no consistent, long-term, durable therapy for vitiligo for all patients, highlighting the unmet need for new safe and effective therapies to control this disease. Recently, JAK inhibitors have been explored as a promising novel treatment option in vitiligo. The JAK and signal transducers and activators of transcription (STAT) pathway is an attractive therapeutic target because IFN-γ-dependent cytokines produced through this pathway have been implicated in the pathogenesis of disease. This literature review describes vitiligo pathophysiology, explains the usefulness of the JAK inhibitors for treatment, and summarizes published case reports, case series, and open-label studies. Research outlined here shows JAK inhibitors in patients with vitiligo have a favorable safety profile and effectively produce repigmentation of lesions, especially with concomitant ultraviolet exposure. Additional studies are required to confirm efficacy, establish safety, and investigate durability of repigmentation.

Abstract
Vitiligo is a common skin disorder characterized by idiopathic, progressive cutaneous hypomelanosis. Vitiligo is associated with several comorbid autoimmune, systemic, and dermatological diseases, primarily thyroid disease, alopecia areata, diabetes mellitus, pernicious anemia, systemic lupus erythematosus, rheumatoid arthritis, Addison's disease, inflammatory bowel disease, Sjögren's syndrome, dermatomyositis, scleroderma, ocular and audiological abnormalities, psoriasis, and atopic dermatitis. It is essential to increase awareness of these comorbidities in order to improve the disease burden and quality of life of patients with vitiligo. Herein, we review the association with the most frequent comorbidities associated with vitiligo.

Abstract
Background: Associations between vitiligo and thyroid disorders have been suggested, However, the prevalence of thyroid disorders in vitiligo vary widely. Purpose: To conduct a systematic review and meta-analysis assessing the prevalence of thyroid disorders in patients with vitiligo. Method: The PubMed, Cochrane Library, EMBASE, CNKI (China National Knowledge Infrastructure), Chongqing VIP database, and Wanfang database from inception to August 2, 2018 were systematically searched. The pooled prevalence and its 95% confidence interval (CI) were calculated. Results: A total of 77 eligible studies were identified and included, published from 1968 to 2018. Six thyroid disorders including subclinical hyperthyroidism, overt hyperthyroidism, subclinical hypothyroidism, overt hypothyroidism, Graves disease, and Hashimoto thyroiditis were described. The numbers of relative studies were 54 in overt hypothyroidism, 50 in overt hyperthyroidism, 25 in subclinical hypothyroidism, 19 in Hashimoto thyroiditis, 16 in Graves disease, and 10 in subclinical hyperthyroidism. The highest prevalence was 0.06 (95% CI: 0.04-0.07) in subclinical hypothyroidism, and the lowest was 0.01 in subclinical hyperthyroidism (95% CI: 0.00-0.01) or Graves disease (95% CI: 0.01-0.02). Conclusion: Six thyroid disorders showed various prevalence in vitiligo. The highest prevalence was in subclinical hypothyroidism, and the lowest was in subclinical hyperthyroidism or Graves disease. Screening vitiligo patients for thyroid disorders seem plausible, in an effort to detect potential thyroid diseases or to assess the risk of future onset.

Abstract
BACKGROUND Associations between vitiligo and thyroid diseases have been reported repeatedly. OBJECTIVE We investigated the associations between vitiligo and overt autoimmune thyroid diseases and thyroid cancer using the Korean National Health Insurance claims database. METHODS We defined patients with vitiligo as those whose records showed ≥4 physician contacts between 2009 and 2013 in which vitiligo was the principal diagnosis. We also established an age- and sex-matched control group without vitiligo (2 per 1 vitiligo patient). The outcomes of interest were concurrent Graves disease and Hashimoto thyroiditis (the patients were taking relevant thyroid medications) and thyroid cancer. RESULTS The study enrolled 73,336 vitiligo patients and 146,672 controls. Patients with vitiligo were at increased risks of Graves disease (odds ratio [OR] 2.610 [95% confidence interval {CI} 2.319-02.938]), Hashimoto thyroiditis (OR 1.609 [95% CI 1.437-1.802]), and thyroid cancer (OR 1.127 [95% CI 1.022-1.242]), compared with the controls. The associations were consistently stronger in males and younger patients. LIMITATIONS Individual clinical information was not available, and the homogeneous population may limit the generalizability of the results. CONCLUSION Vitiligo was significantly associated with overt autoimmune thyroid diseases and overt thyroid cancer.

Abstract
INTRODUCTION The association between vitiligo and thyroid disease is not fully investigated especially in paediatric patients. AIM To determine the incidence of vitiligo and thyroid disorders in children. This is the first report from middle Anatolia and the second report from Turkey. MATERIAL AND METHODS A retrospective chart review was performed to examine the presence of thyroid abnormalities in paediatric patients who had been admitted to the dermatology department with vitiligo. RESULTS A total of 155 paediatric patients, including 80 (52%) male and 75 (48%) female patients were included. The mean age was 8.6 years. Non segmental vitiligo was the most common type of the disease in 140 (90%) reviewed patients, while segmental vitiligo appeared only in 15 (10%) patients. The mean onset of vitiligo was 5.6 ±0.9 years. A family history of vitiligo was found in 14 (9%) children. Thirty-four (22%) patients had thyroid function tests and/or thyroid autoantibody abnormality. All of these patients had non segmental vitiligo. It was statistically significant (p < 0.05) in types of vitiligo and thyroid disease parameters. CONCLUSIONS Our results show that it may be useful to screen thyroid in children with non segmental vitiligo.

Abstract
Autoimmune thyroid diseases (AITDs) are often accompanied by vitiligo, and the sera of patients with vitiligo often demonstrate increased frequencies of thyroid autoantibodies. In this study, we investigated the expression of melanocyte-associated antigens in tissues from patients with Hashimoto's thyroiditis (HT) without vitiligo using immunohistochemistry. Tissues of HT without vitiligo, as well as normal thyroid tissues, were both negative for the expression of NKI/beteb, gp100, tyrosinase-related protein 1 (TRP1), HMB-45 and S100, whereas they were positive for the expression of tyrosinase-related protein 2 (TRP2), lysosome-associated membrane protein 1 (LAMP1) and CD69. Tyrosinase (TYR) was only detected in tissues of HT, and levels of LAMP1 and CD69 were higher in tissues of HT than in normal thyroid tissues (p < 0.005). These results suggest the possibility of antigen crossover and oxidative stress between vitiligo and HT that might represent an immunological basis for secondary HT associated with vitiligo.

Abstract
BACKGROUND AND OBJECTIVE Activity of vitiligo has not been considered as a patient selection criteria in previous studies; we decided to compare the presence of elevated thyroid auto-antibodies in patients with progressive and stable vitiligo. METHODS Seventy-two patients with vitiligo were examined for thyroid problems and were divided into 2 groups of stable and progressive vitiligo according to their history and physical examination. Anti-thyroid peroxidase antibodies (anti-TPO antibodies), thyroxine (T4), and thyroid stimulating hormone (TSH) levels were assessed for all patients. RESULTS Elevated levels of anti-TPO antibodies were observed in 43.7% of the patients with stable vitiligo and in 37.5% of patients with progressive vitiligo, which was not statistically significant (P = .315). CONCLUSION This study not only confirmed thyroid dysfunction in patients with vitiligo but also showed that there was no difference in thyroid dysfunction and anti-TPO antibody levels in the subgroups of patients with stable or progressive vitiligo.

Abstract
Vitiligo and alopecia areata are two cutaneous diseases believed to be primarily autoimmune in pathogenesis. While the coexistence of the two conditions in the same patient has been well-described, reports of the two disease processes occurring in the same location are rare. We report the case of a 10-year-old male with an unremarkable past medical history who presented with a single localized area of poliosis with depigmented underlying skin on the frontal scalp. The hair in the affected area was relatively decreased in density. A punch biopsy of the depigmented patch demonstrated features consistent with both vitiligo and alopecia areata. The decreased number of large hair follicles and a focal peribulbar lymphocytic infiltrate around an anagen follicle were suggestive of alopecia areata. A panel of melanocyte-specific stains revealed absent melanocytes in the epidermis, consistent with vitiligo. Loss of microphthalmia-associated transcription factor-positive root sheath cells was seen, suggestive of loss of melanocyte stem cells. The combination of clinical and histopathologic findings supports the theory of a common pathogenesis of alopecia areata and vitiligo.

Abstract
Background: Though it is well-known that vitiligo is associated with other autoimmune disorders, few Indian studies have focused on the relation between vitiligo, autoimmune thyroid dysfunction and diabetes mellitus. Materials and Methods: This case-control study included 150 new cases of vitiligo and 100 age and sex-matched controls. A complete history and thorough dermatological examination was done. Serum samples from both patients and controls were collected and assayed for triiodothyronine, thyroxine, thyroid-stimulating hormone, anti-thyroid antibodies—anti-thyroid peroxidase and anti-thyroglobulin and fasting plasma glucose. Results: Thyroid hormonal profile revealed autoimmune thyroid dysfunction manifesting as hypothyroidism in 30 (20%) vitiligo patients and two controls (2%). Diabetes mellitus was present in 24 (16%) vitiligo patients and five controls. Seven (4.7%) patients had both hypothyroidism and diabetes mellitus. Conclusion: There is a clear association between vitiligo, autoimmune hypothyroidism and diabetes mellitus. It would be very useful to screen for thyroid dysfunction and diabetes mellitus in all patients with vitiligo.

Abstract
Background: Recently, the abnormal presence of thyroglobulin antibody (TG-Ab) and thyroid peroxidase antibody (TPO-Ab) has been reported in vitiligo patients, but presence of TG-Ab and TPO-Ab in patients of different ages and gender, and its association with vitiligo and thyroid autoimmunity has rarely been reported. The aim of our research was to determine whether vitiligo was associated with thyroid autoimmunity and figure out its relationship with age and gender. Materials and Methods: We analyzed TG-Ab, TPO-Ab in age and gender matched 87 vitiligo patients and 90 healthy controls, the patients of vitiligo who were positive for the presence of TG-Ab and TPO-Ab were followed up to confirm autoimmune thyroid disease subsequently. Results: Results showed that the frequencies of TG-Ab (23.0%, 20/87) positivity and TPO-AB (24.1%, 21/87) in vitiligo patients were significantly higher than that in healthy controls (P < 0.05). Moreover, The positivity for of TG-Ab and TPO-Ab was higher in 11-20-year age group and 21-40-year age group than that in age matched healthy controls. We found female patients with vitiligo had higher positive frequencies of TG-Ab and TPO-Ab than healthy female controls. (34.1% vs. 8.8% and 34.1% vs. 11.1%, P = 0.000 and P = 0.011). When 20 patients with TG-Ab and TPO-Ab positivity were followed up for three monthes, 14 of them (70%) were diagnosed as having autoimmune thyroid disease compared with age-matched healthy controls (16.7%, χ2 = 5.4, P = 0.02). Conclusion: TG-Ab and TPO-Ab are likely to be found in female teenagers with vitiligo, and are relevant with respect to subsequent development autoimmune thyroid disease.

Abstract
Vitiligo is a disease of pigment loss. Most investigators currently consider vitiligo to be a disorder that occurs as a result of autoimmune destruction of melanocytes, supported by identification of antimelanocyte antibodies in many patients, and the presence of comorbid autoimmune disease in patients with and family members of individuals with vitiligo. One-half of vitiligo cases are of childhood onset. This article presents a current overview of pediatric vitiligo including comorbidities of general health, psychological factors, therapeutic options, and long-term health considerations.

Abstract
BACKGROUND Autoimmune comorbidities and circulating autoantibodies have been observed in vitiligo patients, but differences in rate are present according to countries in which the studies were performed, perhaps owing to ethnic diversities or different trigger factors. OBJECTIVE To estimate the prevalence of circulating autoantibodies and overt autoimmune diseases in a fairly large sample of Italian vitiligo patients. METHODS 175 outpatients affected by vitiligo and referred to nine dermatological centers were included in the study. Patients were offered routine blood test, serological testing for thyroid function and search for autoantibodies. RESULTS At least one circulating autoantibody was detected in 61 (41.8%) of 146 subjects who underwent laboratory tests. Anti-thyroperoxidase (25.6%), anti-thyroglobulin (23.4%), antinuclear antibodies (16.8%) and anti-gastric parietal cell antibodies (7.8%) were the most noticed autoantibodies. 74 (41.5%) autoimmune comorbidities, mainly autoimmune thyroiditis (37%), were reported. CONCLUSION The prevalence of autoimmune comorbidities and circulating autoantibodies in this study was in agreement with other surveys conducted on Caucasian patients.

Abstract
Vitiligo is an acquired depigmentary skin disorder of unknown etiology. Vitiligo is not only a disease of melanocytes of the skin. Human melanocytes are derived from the neural crest and are located on various parts of the body. The involvement of skin melanocytes is the most visible one, but a systemic involvement of melanocytes can be observed. Some types of vitiligo (nonsegmental vitiligo) may also be associated with various diseases, mainly with autoimmune pathogenesis. Vitiligo represents a spectrum of many different disorders with different etiologies and pathogeneses, causing a common phenotype: the loss of melanocytes and/or their products. This phenotype is always consistent with a systemic involvement.

Abstract
BACKGROUND/AIMS Vitiligo is considered to be an autoimmune disease and is known to be associated with other autoimmune diseases, particularly affecting the thyroid. In children and adolescents this association has been reported in only a few studies, with varying results. The aim of this study was to examine thyroid function and prevalence of thyroid autoimmunity in children and adolescents with vitiligo and to investigate the utility of screening. METHODS Two hundred and sixty patients with vitiligo were enrolled. Plasma TSH, FT4 and anti-thyroid peroxidase (TPO) antibody concentrations were measured. The prevalence of thyroid dysfunction and autoimmunity were compared to the general healthy paediatric population. RESULTS Autoimmune thyroiditis (AIT) with thyroid hormone disturbances was diagnosed in 16 patients (6.2%). This is significantly higher than the prevalence reported in the general healthy paediatric population. Increased levels of anti-TPO antibodies (= 30 kU/l), without thyroid hormone disturbances, were found in 27 patients (10.5%). CONCLUSION The prevalence of AIT in children and adolescents with vitiligo is significantly higher than in the general population. It may be advantageous to screen thyroid function and antibody levels in all paediatric patients with non-segmental vitiligo. To strengthen recommendations on screening, research on the burden for patients and cost-effectiveness is needed.

Abstract
Although the exact pathogenic processes involved in vitiligo are still unknown, its association with autoimmune disorders and endocrine dysfunction has been reported. One of its associations is with thyroid diseases. The purpose of this retrospective study was to determine the prevalence of thyroid function tests and thyroid autoantibody abnormalities in children diagnosed with vitiligo and compare the results with the literature. The laboratory documents of thyroid function tests (FT3, FT4, and TSH) and thyroid autoantibodies (TgAb and TPOAb) belonging to the pediatric vitiligo patients were studied retrospectively. Thyroid function tests and thyroid autoantibody abnormalities were detected in 20 (25.3%) of the pediatric vitiligo patients. Thirteen (16.4%) patients were evaluated as subclinical hypothyroidism, two (2.5%) were evaluated as hypothyroidism, and five (6.3%) were evaluated as euthyroidism. Thyroid autoantibodies were found to be positive in nine (11.3%) patients. Previously reported prevalence of thyroid disease in children with vitiligo ranged from 10.7 to 24.1%, and the prevalence of 25.3% determined in this study was compatible with the literature. Also, the high rate of subclinical hypothyroidism determined in these patients attracted attention to the probable development of overt hypothyroidism in a long term. Thus, our results suggest that thyroid function tests and thyroid autoantibodies should be analyzed in children with vitiligo.

Abstract
Heat shock proteins (HSPs) are proteins that are expressed under variety of stresses including pathologic conditions. How stresses affect vitiligo is not fully understood and little is known about the role of HSPs generally and Hsp70 specifically in vitiligo. The current study investigated the expression of Hsp70 in vitiliginous (32) and normal skin (10) by immunohistochemistry together with correlating this expression with the clinicopathologic parameters in the studied vitiligo group. Hsp70 was expressed in the cytoplasm of epidermis in all normal skin compared with its localization to the cytoplasm in 35.5% and to the nuclei in 64.5% of epidermis in vitiligo lesions. Intense (P < .001) and diffuse (P < .001) expression of Hsp70 was in favor of vitiligo skin compared with normal skin. Nuclear form of Hsp70 tended to be expressed in progressive forms of the disease. The percentage of Hsp70 expression tended to be decreased with the duration of the disease. From the present study, up-regulation of HSP 70, in the form of its intense and diffuse expression, may be blamed in pathogenesis of vitiligo. Nuclear localization of HSP 70 may be more important than its presence or absence, beside it may be related to progression of the disease.

Abstract
BACKGROUND Thyroid disease has been suggested to be associated with vitiligo. However, the outcomes of prevalence studies on thyroid disease in vitiligo vary widely. OBJECTIVES To summarize and critically appraise current evidence of the prevalence of thyroid diseases in vitiligo. METHODS A systematic review was performed searching the electronic databases OVID MEDLINE, OVID EMBASE and PubMed. Guidelines for the critical appraisal of studies on prevalence of a health problem were adapted to evaluate the methodological quality of the included studies. Results were analysed in a meta-analysis with a risk ratio (RR). RESULTS Forty-eight studies published between 1968 and 2012 met the inclusion criteria. Most of the studies (50%) were of fair methodological quality, whereas 18 studies (38%) were of poor quality and six studies (12%) were of good quality. Thyroid disease, autoimmune thyroid disease and presence of thyroid-specific autoantibodies showed a mean prevalence of, respectively, 15·1%, 14·3% and 20·8% in patients with vitiligo and an RR of, respectively, 1·9, 2·5 and 5·2 (all statistically significant). This review shows an increased prevalence and an increased risk of (autoimmune) thyroid disease in patients with vitiligo compared with nonvitiligo. This risk seems to increase with age. CONCLUSIONS Clinicians should be aware of this increased risk in patients with vitiligo and should be attentive for symptoms of thyroid disease. To make recommendations on screening for thyroid disease in patients with vitiligo future research of good methodological quality, including differentiation of vitiligo types and the use of standardized outcome measures, is needed.

Abstract
OBJECTIVE To identify the prevalence of autoimmune thyroid disease (AITD) in Asian Indian patients with vitiligo and to compare the clinical profile between thyroid peroxidase (TPO) antibody-positive and TPO antibody-negative groups. METHODS In this cross-sectional, case-controlled study, 50 patients with vitiligo (29 women and 21 men) were included. Patients with previous disorders, irradiation, or surgical procedures involving the thyroid were excluded from the study. All participants underwent a complete physical examination, and a single fasting blood sample was analyzed for thyroid function (triiodothyronine, thyroxine, thyroid-stimulating hormone, and TPO and thyroglobulin antibodies), inflammatory and immunologic markers (erythrocyte sedimentation rate, C-reactive protein, and rheumatoid factor), and serum calcium, phosphorus, and alkaline phosphatase concentrations. All patients underwent thyroid ultrasonography, and the data were analyzed by appropriate statistical methods. RESULTS The mean age of the study participants was 42.7 ± 17 years, and 14 of 50 patients (28%) had TPO antibody positivity. A goiter was present in 11 of 50 patients, and the thyroid volume by ultrasonography was similar between the 2 groups. Subclinical hypothyroidism was found in 14 of 50 patients (28%) but more frequently in the TPO antibody-positive group (8 of 14 or 57%) than in the TPO antibody-negative group (6 of 36 or 17%). The prevalence of AITD was 20 of 50 patients (40%) when the TPO antibody-positive group and those with subclinical hypothyroidism were considered collectively. None of the patients had overt hypothyroidism or hyperthyroidism. All other clinical, biochemical, and inflammatory variables did not differ significantly between the TPO antibody-positive and antibody-negative groups. CONCLUSION Our data showed a 40% prevalence of thyroid disease in patients with vitiligo in India. The risk is exacerbated in patients with thyroid autoimmunity; thus, regular screening of patients with vitiligo for AITD is needed.

Abstract
BACKGROUND Nonsegmental vitiligo is considered to be an autoimmune disease and is known to be associated with other autoimmune diseases, particularly affecting the thyroid. Screening patients with nonsegmental vitiligo for thyroid function and for the presence of thyroid autoantibodies has been recommended. OBJECTIVE To investigate the prevalence of thyroid dysfunction and thyroid peroxidase-specific (TPO) antibodies in a large cohort of patients with nonsegmental vitiligo in order to help decide whether routine screening is justified. METHODS A total of 434 adults with nonsegmental vitiligo who were referred to our institute were enrolled. Thyroid function and anti-TPO antibody titres were assessed in those patients who had no history of thyroid disease or recent thyroid screening. RESULTS Forty-three patients had already been diagnosed with thyroid dysfunction, and in 27 patients the general practitioner had performed a thyroid function test with negative results <3months previously. In these patients, thyroid function assessment was not repeated. The remaining 364 patients were screened for thyroid dysfunction. Overt hypothyroidism was newly diagnosed in three (0·8%) patients; subclinical disease was found in 10 (2·7%) patients and increased levels of TPO antibodies, without thyroid disease, were found in 49 (13·5%) patients. An elevated risk for thyroid disease was found among older women and in women with a positive family history of thyroid disease. CONCLUSION The overall prevalence of thyroid dysfunction in adult patients with nonsegmental vitiligo was higher than reported in the general population. However, the number of newly diagnosed cases with overt and subclinical thyroid dysfunction in our population was low. Most patients had already been diagnosed by their general practitioner and had symptoms indicative for thyroid disease. Thyroid disease was found predominantly among older women and in subjects with a positive family history of thyroid disease. Thyroid screening including anti-TPO antibodies is advisable in these high-risk subpopulations.

Abstract
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 autoimmune thyroid diseases. METHODS A cross-sectional study was conducted through analysis of the medical records of patients diagnosed with vitiligo in the AME-UNISUL Outpatient Clinic of Dermatology and at HU-UFSC. The clinical and laboratorial characteristics of these patients were assessed. RESULTS 85 medical records were evaluated; 56 patients were female, with a mean age of 37.14 years and mean onset age of 25.25 years. Vitiligo vulgaris occurred in 70.6%. Autoimmune thyroid diseases were found in 22.4%. Other autoimmune diseases were identified in 5.9%. Patients with positive thyroid autoantibodies showed a probability of extension of vitiligo greater than 25%. There was no statistical difference with regard to the clinical characteristics of vitiligo in patients with or without autoimmune thyroiditis with hormonal change. CONCLUSION The findings of this study are similar to those obtained by other authors, showing that autoimmune thyroid diseases are more common in patients with vitiligo.

Abstract
BACKGROUND It is a hospital based study focusing on epidemiological aspects of vitiligo and association with autoimmune disorders. There are few studies elucidating the association of autoimmune disorders with vitiligo in the Indian population. Our study is a small attempt in this direction. AIM To study epidemiological parameters of vitiligo and to study coexistence of autoimmune disorders. MATERIALS AND METHODS Records of 33,252 new patients attending the dermatology outpatient department from June 2002 to June 2008 were analysed for the presence of vitiligo and details of important epidemiological variables, and associated autoimmune disorders of these patients were collected and analysed. RESULTS Total number of vitiligo patients was 204. Proportion of vitiligo patients was 0.61%. Male:female proportion was almost equal. Family history of vitiligo was seen in 3.43% of cases. Associated autoimmune disorders were seen in 2.94% cases and were mainly skin associated autoimmune diseases (morphoea, alopecia areata, discoid lupus erythematosus, and pemphigus erythematosus) except for one case of Grave's disease. CONCLUSION Association of vitiligo with other autoimmune diseases emphasizes autoimmune aetiology of vitiligo. This study also emphasizes the need to actively look for, and if necessary, investigate patients with vitiligo for other autoimmune diseases.

Abstract
BACKGROUND Vitiligo is the most common pigmentation-related disorder worldwide. An autoimmune etiology is widely considered, and genetic factors may play an important role in its pathogenesis. The purpose of this study was to assess the incidence of thyroid dysfunctions and autoimmune thyroiditis in children with vitiligo and to identify related factors. METHODS Fifty children with vitiligo and 50 control children were enrolled. Data on age, onset, duration, disease activity, presence of thyroid disorder, other autoimmune diseases, halo nevi, poliosis, and mucosal vitiligo were determined. Serum free triiodothyronine, free thyroxine, total T3, total T4, thyroid-stimulating hormone, and antibodies to thyroperoxidase and thyroglobulin were measured. Thyroid gland efficiency was evaluated. RESULTS The mean age at onset of vitiligo was 7.26 ± 4.43 years. The duration of vitiligo was 2.26 ± 2.95 years. Vulgaris-type vitiligo was the most common form in our patients (56%), and 42% reported at least one family member with thyroid disorder, autoimmune disease, or both. Overt hypothyroidism or hyperthyroidism were not detected. We found a significant association between autoimmune thyroiditis and both sex and disease duration (P = 0.046 and P = 0.07, respectively), but no association between autoimmune thyroiditis and age, age at onset of vitiligo, halo nevi, poliosis, mucosal involvement, disease activity, or family history of vitiligo, autoimmunity, or thyroid disorders. CONCLUSIONS Children with vitiligo show an increased incidence of autoimmune thyroiditis. Children with vitiligo, especially girls and subjects with generalized/vulgaris-type vitiligo, should be screened annually for thyroid function and antithyroid antibodies to assist in the early diagnosis and therapy of autoimmune thyroiditis.

Abstract
BACKGROUND It is stated that patients with vitiligo have an increased risk of developing autoimmune diseases. OBJECTIVE The aim of this study was to estimate the prevalence of autoantibodies or overt autoimmune diseases in a group of vitiligo patients examined among a sample deemed to be representative of the general population of young men living in southern Italy. METHODS A total of 60 vitiligo patients were identified among 34,740 potential conscripts visited to evaluate their fitness to compulsory service in Italian Navy, obtaining a prevalence of 0.17% (95% CI: 0.13-0.22), which was deemed the prevalence of vitiligo in the Italian general population of the same age and sex. Forty of these vitiligo patients underwent blood test including also the search of the main autoantibodies. RESULTS Circulating autoantibodies were detected in 42.5% of subjects. Anti-thyroglobulin antibodies were documented in 27.5%, anti-thyroperoxidase in 22.5%, anti-smooth muscle in 17.3%, anti-nuclear, anti-mitochondrial and anti-gastric parietal cells in 2.5% respectively. Only in two cases (5%) an overt thyroid disease was diagnosed. No significant association between the extension of the skin involved ⁄ clinical course of the disease and circulating autoantibodies was detected. Circulating autoantibodies (particularly anti-thyroid antibodies) were statistically associated with a lower duration of the disease. CONCLUSIONS In agreement with other studies, autoantibodies in the lack of clinical manifestations have been frequently observed in our vitiligo patients, especially during the early phase of the disease. The clinical significance of this finding seems to be limited, with the possible exception of thyroid disease, and it needs further exploration, through large cohort studies.

Abstract
BACKGROUND Vitiligo is an acquired depigmenting disorder characterized by the loss of melanocytes from the epidermis with the development of white patches in various distribution. The pathogenesis of vitiligo is still unknown, but the association with autoimmune disorders and organ specific autoantibodies, supports the hypothesis of an autoimmune pathogenesis. AIM The aim of the present study was to investigate if autoantibodies present in sera of patients affected by vitiligo may be able to interfere with the activity of the αMSH on the melanocortin 1 receptor (MC1R). MATERIALS/ SUBJECTS AND METHODS: IgG from the sera of 41 patients with vitiligo associated or not with thyroid autoimmune diseases or other autoimmune pathologies were incubated with HBL20 cells (human malignant melanocytes expressing the MC1R) in the presence of a sub-maximal dose of αMSH. A normal IgG range was determined by using IgG extracted from 30 control sera of normal subjects. RESULTS None of the IgG from vitiligo patients was able to inhibit αMSH-stimulated cAMP production in HBL20 cells. CONCLUSIONS Autoantibodies against MC1R are rare or absent in sera of vitiligo patients.

Abstract
BACKGROUND Vitiligo is a common skin depigmenting disease, which is thought to have, at least partly, an autoimmune aetiology. AIM To explore the correlation between paediatric vitiligo and other associated diseases, with an emphasis on autoimmune thyroiditis (AT). METHODS In total, 363 paediatric patients (198 boys, 165 girls) with vitiligo and 93 healthy children (55 boys, 38 girls) were screened for autoimmune thyroiditis. The two groups were matched for age and gender. Children with vitiligo were split into two groups according to type (segmental and nonsegmental vitiligo). Demographic data, clinical features and examinations were recorded using questionnaires. Thyroid function tests including free triiodothyronine, free thyroxine and thyroid-stimulating hormone were performed. Anti-thyroid peroxidase antibody) and anti-thyroglobulin antibody levels were assessed as well. Other associated diseases were also monitored in this study. RESULTS Of the 363 patients, 43 (11.8%) had abnormal levels of studied thyroid parameters, compared with 4 of the 93 controls (4.3%); the difference was significant (P = 0.04). The alterations of thyroid parameters and the incidence of AT in patients with nonsegmental vitiligo were both significantly different (P < 0.05, P = 0.04) relative to the segmental vitiligo group. Of the 363 patients, 67 (18.5%) had other associated diseases. There were no differences in the rates of other associated diseases between patients with segmental vitiligo and those with nonsegmental vitiligo (P > 0.05). CONCLUSIONS A significant incidence of thyroid dysfunction was found in paediatric patients with nonsegmental vitiligo. As vitiligo usually appears before the development of the thyroid disease, it may be advantageous to screen thyroid functions and antibody levels in all paediatric patients with vitiligo, especially those with nonsegmental vitiligo.

Abstract
A 72-year-old female and a 57-year-old male with chronic hepatitis C were treated with a combination therapy of pegylated interferon (PEG-IFN)-α 2a (180 μg s.c. once a week) and ribavirin (1,000 mg orally daily). This resulted in the destruction of melanocytes at the injection site in both patients. In the male patient, the depigmentation progressed to the surrounding skin area. The dermatologist concurred with vitiligo as the diagnosis in both patients. Injection and surrounding site vitiligo associated with PEG-IFN-α 2b treatment for hepatitis C was noticed in previous case studies. For the first time, the case reports below highlight the same immunological adverse event secondary to PEG IFN-α 2a/ribavirin combination therapy and explain, in part, the complex interaction between host immune response and viral genotype. In addition, we systematically review drug-induced vitiligo and autoimmune diseases associated with the depigmentation disorder.

Abstract
BACKGROUND Vitiligo often starts in childhood. It is traditionally divided into segmental vitiligo and nonsegmental vitiligo. There are limited data regarding the clinical characteristics of both forms and no comparative study has been performed. OBJECTIVE To compare the clinical features of nonsegmental and segmental vitiligo in children. PATIENTS AND METHODS We performed a prospective observational study. Consecutive children with vitiligo seen between October 2005 and December 2007 in the 11 French Departments of Pediatric Dermatology were included. A standardized evaluation was completed after total body clinical examination. A second examination was performed 1 year after inclusion. The clinical characteristics of segmental vitiligo and nonsegmental vitiligo were compared. RESULTS A total of 114 children with vitiligo were included. Compared with segmental vitiligo, nonsegmental vitiligo was associated with a higher number of lesions (more than 5 patches in 65.17% vs 20% of patients, P < .0001) and a larger body surface area of involvement (9.8% +/- 2.51% vs 3.48% +/- 1.6%, P +/- .01). A higher incidence of the Koebner phenomenon (47.19% vs 24%, P = .03), and more frequent progression of the disease (23.29% vs 5.56%, P = .043) were found in nonsegmental vitiligo. Hyperpigmented rims surrounding patches of vitiligo were only seen in nonsegmental vitiligo (8.99% vs 0% (P = .007). Sixty-four children (56%) had laboratory investigations performed; thyroid abnormalities were found only in nonsegmental vitiligo (11.23% vs 0%, P = .0001). LIMITATIONS Not all patients underwent laboratory investigations. CONCLUSIONS Segmental and nonsegmental types of vitiligo have distinguishing clinical characteristics.
