Eleftheriadou V, Delattre C, Chetty-Mhlanga S, Lee C, Girardat-Rotar L, Khan I, Mathew A, Thompson AR. Burden of disease and treatment patterns in patients with vitiligo: findings from a national longitudinal retrospective study in the UK. Br J Dermatol 2024; 191:216-224. [PMID: 38534198 DOI: 10.1093/bjd/ljae133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 03/21/2024] [Accepted: 03/21/2024] [Indexed: 03/28/2024]
Abstract
BACKGROUND UK studies examining vitiligo burden and vitiligo-related healthcare resource utilization (HCRU) are lacking. OBJECTIVE To describe the incidence and prevalence of vitiligo, the demographic and clinical characteristics of patients with vitiligo, vitiligo burden, HCRU, incidence of mental health comorbidities and management strategies, including treatment patterns. METHODS This retrospective study used UK Clinical Practice Research Datalink and Hospital Episode Statistics databases to analyse patients with vitiligo from 1 January 2010 to 31 December 2021. RESULTS Among 17 239 incident patients, mean incidence of vitiligo was 0.16 (2010-2021) per 1000 person-years [PY; range 0.10 (2020-COVID-19) to 0.19 (2010/2013/2018)]; among 66 217 prevalent patients, prevalence increased from 0.21% (2010) to 0.38% (2021). The most common comorbidities recorded after vitiligo diagnosis were diabetes (19.4%), eczema (8.9%), thyroid disease (7.5%) and rheumatoid arthritis (6.9%). Mental health diagnoses recorded at any time included depression and/or anxiety (24.6%), depression (18.5%), anxiety (16.0%) and sleep disturbance (12.7%), and recorded after vitiligo diagnosis in 6.4%, 4.4%, 5.5% and 3.9%, respectively. Mental health comorbidities were more common in White (e.g. depression and/or anxiety 29.0%) than in Black (18.8%) and Asian (16.1%) patients. In adolescents, depression and/or anxiety was most commonly diagnosed after a vitiligo diagnosis than before (7.4% vs. 1.8%). Healthcare resources were used most frequently in the first year after vitiligo diagnosis (incident cohort), typically dermatology-related outpatient appointments (101.9/100 PY) and general practitioner consultations (97.9/100 PY). In the year after diagnosis, 60.8% of incident patients did not receive vitiligo-related treatment (i.e. topical corticosteroids, topical calcineurin inhibitors, oral corticosteroids or phototherapy), increasing to 82.0% the next year; median time from diagnosis to first treatment was 34.0 months (95% confidence interval 31.6-36.4). Antidepressants and/or anxiolytics were recorded for 16.7% of incident patients in the year after diagnosis. In 2019, 85.0% of prevalent patients did not receive vitiligo-related treatments. CONCLUSION Most patients were not on vitiligo-related treatments within a year of diagnosis, with the time to first treatment exceeding 2 years, suggesting that vitiligo may be dismissed as unimportant. New effective treatments, early initiation and psychological intervention and support are needed to reduce the vitiligo burden on patients.

Influences of vitiligo-associated characteristics on the occurrence of diabetes mellitus: Interactive analysis of a cross-sectional study. Exp Dermatol 2023; 32:1805-1814. [PMID: 37584091 DOI: 10.1111/exd.14904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 07/02/2023] [Accepted: 07/24/2023] [Indexed: 08/17/2023]
Abstract
The risk of diabetes mellitus (DM) in vitiligo patients is higher than that in non-vitiligo population. Our goal was to explore the influencing factors for DM in vitiligo patients. A matched-pair design of 107 cases with DM and 428 controls without DM was conducted among vitiligo patients in Xijing hospital from January 2010 to October 2021. The baseline characteristics of patients were analysed based on standard descriptive statistics. The vitiligo-associated characteristics were analysed by logistic regression to identify influencing factors of DM. Interaction analysis was performed to explore the additive interactions between vitiligo-associated characteristics and baseline characteristics. After adjustment for the baseline characteristics, the severity of vitiligo [odds ratio (OR) = 2.47, 95% confidence interval (CI): 1.47-4.14] and onset age of vitiligo (OR = 0.98, 95% CI: 0.97-0.99) had a significant correlation with occurrence of DM. The severity of vitiligo had additive interaction with family history of diabetes [relative excess risk due to interaction (RERI) = 132.51 (95% CI: 5.51-1100.20), attributable proportion (AP) = 0.91 (95% CI: 0.17-0.95), synergy index (S) = 11.53 (95% CI: 1.32-100.5)] and with smoking history [RERI = 6.54 (95% CI: 0.67-19.83), AP = 0.64 (95% CI: 0.04-0.80), S = 3.48 (95% CI: 1.17-10.36)]. Earlier onset age of vitiligo and greater BSA involvement might be two independent risk factors for DM in vitiligo patients. Interaction assessment identified the severity of vitiligo as additive interaction factors with diabetes family history and with smoking history for the DM occurrence.

Abstract
Introduction There is scanty evidence regarding the role of autoimmunity in vitiligo, especially in the Asian population. Moreover, the existing studies reported conflicting results. This prompted the investigators to identify the association of thyroid autoimmunity with vitiligo by employing a case-control design in this setting. Methodology The present study was a hospital-based case-control study conducted in one of the tertiary care hospitals of North India. We recruited 30 subjects aged 16-60 years with vitiligo attending the skin and venereal diseases outpatient department. The subjects attending the general medicine outpatient department without having a diagnosis of vitiligo were considered for the control group. Thyroid hormones (FT3 and FT4), thyroid-stimulating hormones, anti-thyroid peroxidase (anti-TPO) antibodies, and anti-thyroglobulin (anti-TG) antibodies were the primary investigations performed among the study subjects. Results The mean age of the study subjects was 31.3 (SD: 13.3) years. Both the case and control groups were comparable based on selected socio-demographic variables (p > 0.05). There was a statistically significant difference in terms of mean anti-TPO and anti-TG values between the case and control groups in which subjects with vitiligo reported significantly higher values (p < 0.05). Conclusion Our study reported a significant elevation in the mean values of the thyroid antibodies (anti-TG and anti-TPO antibodies) in vitiligo subjects compared to control subjects in this setting. Hence, screening for autoimmune thyroid diseases among patients with vitiligo is suggested for the early detection and the initiation of appropriate intervention.

Different vitiligo characteristics as predictors of increased risk of metabolic syndrome and insulin resistance: A case-control study. J Cosmet Dermatol 2022; 21:7170-7177. [PMID: 36208004 DOI: 10.1111/jocd.15446] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 08/07/2022] [Accepted: 10/03/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND Autoimmune and metabolic disturbances have been reported in association with vitiligo, highlighting possible systemic associations that should be considered. AIMS To assess the possible association of metabolic syndrome (MetS) as well as insulin resistance (IR) with vitiligo in different age groups. METHODS This case-control study included 142 patients with vitiligo aging ≥ 6 years and 142 age- and sex-matched controls. Participants were assessed for MetS using the International Diabetes Federation (IDF) criteria in addition to IR via homeostasis model assessment of IR (HOMA-IR). The study was registered at Clinical Trials.gov, Identifier: NCT03622320, on August 9, 2018. RESULTS As per the IDF criteria, patients with vitiligo showed significantly more frequent association with high fasting plasma glucose levels, high blood pressure readings, central obesity, dyslipidemia, and MetS than controls (p = 0.020, p = 0.034, p = 0.014, p < 0.001, and p = 0.002, respectively). Moreover, patients with vitiligo have significantly higher levels of fasting insulin and HOMA-IR (p ≤ 0.001). Results obtained from patients with vitiligo and controls with coexistent MetS/IR demonstrated vitiligo as a risk factor for both MetS and IR. Univariate and multivariate logistic regression highlighted that older age was the significant independent predictor for MetS and IR. CONCLUSION Patients with vitiligo showed a significantly higher incidence of MetS than controls. Vitiligo per se can be considered a risk factor for MetS and IR. Therefore, regular follow-up and early metabolic derangement diagnoses are mandatory.

Abstract
Vitiligo has been reported to be associated with a variety of diseases, but it has not been systematically reviewed. Therefore, we aimed to identify prevalent diseases in patients with vitiligo and quantify their associations compared with those in healthy controls. A comprehensive search of MEDLINE and EMBASE from the inception to June 2022 was conducted. Observational studies on prevalent diseases in patients with vitiligo compared with those in healthy controls were included, whereas studies limited to pediatrics or providing only laboratory results were excluded. A total of 78 studies were eligible for analyses. Patients with vitiligo showed higher risks of having comorbid autoimmune and connective tissue diseases, including alopecia areata (OR = 2.63, 95% confidence interval [CI] = 2.50‒2.78), discoid lupus erythematosus (OR = 2.54, 95% CI = 1.74‒3.72), Sjogren's syndrome (OR = 2.50, 95% CI = 1.98‒3.16), myasthenia gravis (OR = 2.30, 95% CI = 1.74‒3.02), systemic lupus erythematosus (OR = 1.96, 95% CI = 1.52‒2.52), and rheumatoid arthritis (OR = 1.82, 95% CI = 1.55‒2.15). Thyroid diseases, diabetes mellitus, metabolic syndrome, sensorineural hypoacusis, and ophthalmic abnormalities were also more prevalent in patients with vitiligo. In conclusion, vitiligo is associated with various systemic diseases. Physicians should evaluate and manage potential comorbid conditions in patients with vitiligo.

Abstract
Vitiligo is a common depigmenting skin disorder characterized by the selective loss of melanocytes. Autoimmunity, genetic, environmental, and biochemical etiology have been proposed in vitiligo pathogenesis. However, the exact molecular mechanisms of vitiligo development and progression are unclear, particularly for immunometabolism. Sporadic studies have suggested mitochondrial dysfunction, enhanced oxidative stress, and specific defects in other metabolic pathways can promote dysregulation of innate and adaptive immune responses in vitiligo. These abnormalities appear to be driven by genetic and epigenetic factors modulated by stochastic events. In addition, glucose and lipid abnormalities in metabolism have been associated with vitiligo. Specific skin cell populations are also involved in the critical role of dysregulation of metabolic pathways, including melanocytes, keratinocytes, and tissue-resident memory T cells in vitiligo pathogenesis. Novel therapeutic treatments are also raised based on the abnormalities of immunometabolism. This review summarizes the current knowledge on immunometabolism reprogramming in the pathogenesis of vitiligo and novel treatment options.

Abstract
HINTERGRUND UND ZIELE Ziel dieser Studie war die Untersuchung des Zusammenhangs zwischen Vitiligo und dem metabolischen Syndrom (MetS) sowie dessen relevanten Komponenten. MATERIAL UND METHODEN Die Datenbanken PubMed, Web of Science, Cochrane Library und Embase wurden von deren Beginn bis zum 30. März 2021 nach relevanten Studien durchsucht. Querschnitts- und Fall-Kontroll-Studien, die entweder die Prävalenz oder die Odds-Ratio [OR] des MetS oder seiner Komponenten bei Vitiligo-Patienten berichteten, wurden eingeschlossen. Die Daten wurden entsprechend der Heterogenität entweder mit einem Zufallseffektmodell oder einem Modell mit festen Effekten gepoolt. ERGEBNISSE Es wurden 30 Studien mit insgesamt 28.325 Vitiligo-Patienten eingeschlossen. Signifikante Zusammenhänge wurden zwischen Vitiligo und Diabetes mellitus (gepoolte OR, 3,30; 95 %-Konfidenzintervall [KI], 2,10-5,17) sowie zwischen Vitiligo und Adipositas (gepoolte OR, 2,08; 95 %-KI, 1,40-3,11) ermittelt. Die Gesamtprävalenz der Hypertonie bei Patienten mit Vitiligo betrug 19,0 % (95 %-KI, 2,0 %-36,0 %). SCHLUSSFOLGERUNGEN Unserer Ergebnisse lassen auf einen Zusammenhang zwischen Vitiligo und Diabetes mellitus sowie Hypertonie schließen. Dermatologen wird empfohlen diese Zusammenhänge zu berücksichtigen, um potenzielle Begleiterkrankungen bei Vitiligo-Patienten zeitnah zu identifizieren. Zudem wird Vitiligo-Patienten empfohlen, Parameter wie BMI, Blutzuckerspiegel und Blutdruck zu überwachen und bei auffälligen Veränderungen dieser Parameter unverzüglich einen Spezialisten zu konsultieren.

Abstract
BACKGROUND AND OBJECTIVES This study aimed to investigate the association of vitiligo with metabolic syndrome (MetS) and its relevant components. MATERIAL AND METHODS We searched PubMed, Web of Science, Cochrane Library and Embase databases from inception to March 30, 2021, for relevant studies. Cross-sectional and case-control studies that reported either the prevalence or odds ratio [OR] of MetS or its components in vitiligo patients were included. Data were pooled using either random-effects model or fixed-effects model according to the heterogeneity. RESULTS Thirty studies with a total of 28,325 vitiligo patients were included. Significant associations were found between vitiligo and diabetes mellitus (pooled OR, 3.30; 95 % confidence interval [CI], 2.10-5.17) and between vitiligo and obesity (pooled OR, 2.08; 95 % CI, 1.40-3.11). The overall prevalence of hypertension in the patients with vitiligo was 19.0 % (95 % CI, 2.0 %-36.0 %). CONCLUSIONS Our findings suggest the association of vitiligo with diabetes mellitus, obesity, and hypertension. It is recommended for dermatologists to take these associations into account so as to identify potential comorbidities promptly in vitiligo patients. Additionally, vitiligo patients are advised to monitor the indexes including BMI, blood glucose, and blood pressure levels and the consultation with specialists is necessary upon abnormal changes of these indexes.

Abstract
BACKGROUND Metabolic syndrome (MetS) has been associated with various skin conditions including vitiligo. However, the association between these 2 conditions has yet to be determined by quantitative meta-analysis. OBJECTIVE The aim of this paper was to determine the association between vitiligo and metabolic syndrome via systematic review and meta-analysis. METHODS A systematic literature search of Pubmed, Embase, Cochrane, and Web of Science was performed for all published literature prior to August 16, 2020. Case control and prospective cross-sectional studies analyzing the association between vitiligo and MetS were included in this review. The primary outcome measures include the type of vitiligo, diagnostic criteria for MetS, components of MetS (waist circumference, blood pressure, triglycerides, fasting glycemic index, and high-density lipoprotein cholesterol), low-density lipoprotein cholesterol levels, and BMI. A meta-analysis was performed to evaluate the prevalence and association of MetS in patients with vitiligo. RESULTS A total of 6 studies (n=734 participants) meeting eligibility criteria were included for systematic review and meta-analysis. The pooled prevalence of MetS in patients with vitiligo was (0.296, 95% CI 0.206, 0.386; P<.001). Patients with vitiligo were no more likely to develop MetS compared to control patients (odds ratio 1.66, 95% CI 0.83, 3.33; P=.01). A leave-one-out sensitivity analysis showed a significant association between MetS and vitiligo (P<.001). Significant elevations in fasting glycemic index (mean difference 5.35, 95% CI 2.77, 7.93; P<.001) and diastolic blood pressure (mean difference 1.97, 95% CI 0.02, 3.92; P=.05) were observed in patients with vitiligo compared to control patients. CONCLUSIONS The association between vitiligo and metabolic syndrome carries important clinical implications. Dermatologists and other multidisciplinary team members should remain vigilant when treating this patient population in order to prevent serious cardiovascular complications that may arise as a result of metabolic disease.

Abstract
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.

Abstract
Vitiligo is an autoimmune condition primarily affecting the skin where there is destruction of melanocytes characterized by pinkish-white patches on the skin. It is associated with other autoimmune diseases such as thyroid disease, rheumatoid arthritis, diabetes mellitus, and metabolic syndrome. Metabolic syndrome is a constellation of disorders including insulin resistance, hypertension, dyslipidemia, and obesity, and is considered a leading cause of cardiovascular morbidity. Simvastatin is a potent hypolipidemic drug that also possesses immunomodulating properties and is a common drug used in dyslipidemia and cardiovascular diseases. This study aimed to assess the association between vitiligo and metabolic syndrome and explore the immunomodulating properties of simvastatin for use in vitiligo. We reviewed various articles from PubMed, ResearchGate, and Google Scholar using different keywords and Medical Subject Headings and finalized 33 studies to be used in our review. The articles selected showed a positive association between vitiligo and metabolic syndrome or one of the component diseases of metabolic syndrome. The benefits of using simvastatin were also addressed by few articles attributing to its antioxidant and immunomodulating effect. However, there was no concrete explanation justifying the association between vitiligo and metabolic syndrome due to a limited number of studies and smaller sample size. Large-scale clinical trials should be conducted to evaluate the use of simvastatin as an immunomodulator in vitiligo to prevent possible metabolic complications.

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
BACKGROUND Data have been accumulating in the past few years that identify vitiligo as a disorder with systemic implications. RESULTS AND METHODS In this hospital-based, cross-sectional, case-control study, 50 patients with non-segmental vitiligo and 50 age- and sex-matched controls underwent analysis of serum lipid profile, oxidative stress biomarkers and carotid duplex. Hydrogen peroxide (H2 O2 ) and malondialdehyde (MDA) were significantly higher in patients than controls (p-value < .001, <.001, respectively); on the other hand, total antioxidant capacity (TAC) was significantly lower in patients than controls (p-value = .001). A significantly higher percentage of patients had hypercholesterolemia and borderline high, high or very high levels of LDL-C, compared to controls (p-value = .001 and .001, respectively). Atherosclerotic plaques and increased common carotid intima media thickness were significantly detected in patients versus controls. DISCUSSION Results of the present study suggest that a subset of patients with vitiligo are at a higher risk of developing dyslipidemia and atherosclerosis, which might increase their future risk for the development of cardiovascular disease. Confirmation of these findings would subsequently influence investigative and the treatment strategies in the management plan of vitiligo patients in the near future. SIGNIFICANCE Vitiligo patients might be at a higher risk of developing dyslipidemia and atherosclerosis, which might increase their risk for the development of cardiovascular disease necessitating prophylactic measures to improve prognosis. Our results might influence the investigative and treatment strategies in the management plan of vitiligo patients in the near future.

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
OBJECTIVES To identify the proportion and risk of chronic diseases in vitiligo patients in a tertiary hospital in Riyadh, Kingdom of Saudi Arabia (KSA). Methods: A retrospective case-control study included 61 vitiligo patients and 61 normal non-dermatology controls in King Abdulaziz Medical City, Riyadh, KSA between January and September 2016. Age, gender and co-morbid diseases including hypertension, diabetes, dyslipidemia, obesity and hypothyroidism were retrieved from participants' charts and medical records. Proportion and mean were used to describe the variables, and odds ratio (OR) was used to test the data. Results: A total of 122 participants (34 males, 88 females) equally divided in cases and controls. The mean age was 45±19 years for the case and 40±17 years for the control group. The proportion of diabetes (51%) was higher in the case group than the control (33%) (OR: 0.47; 95% confidence interval [CI]: 0.23-0.98; p=0.04). Dyslipidemia was significantly associated with vitiligo (67%) compared with the control group (48%) (OR: 0.44; 95% CI: 0.21-0.92; p=0.03). Vitiligo participants had a significantly increased risk of having hypothyroidism (26%) compared with the control group (10%) (OR: 0.31; 95% CI: 0.11-0.85; p=0.02). Conclusion: There is an increased risk of chronic diseases among vitiligo patients including diabetes, dyslipidemia, hypothyroidism, renal injuries, and obesity.

Abstract
Context: Diabetes mellitus is associated with many skin manifestations including vitiligo. Vitiligo occurs more commonly in Type 1 diabetes mellitus. A few recent studies have shown its increased occurrence in Type 2 diabetes mellitus. Aims: This study aims to study the prevalence of vitiligo in Type 2 diabetic patients and to compare the prevalence of vitiligo in age- and sex-matched group of nondiabetic population. Settings and Design: The present study was a hospital-based cross-sectional study conducted in the Department of Dermatology in a tertiary care hospital. Subjects and Methods: Six hundred consecutive consenting patients of Type 2 diabetes were included in the study group and age- and sex-matched controls were healthy nondiabetic adult volunteers attending the Department of Dermatology. Fasting and postprandial blood sugar levels were done. A complete history, physical examination, and wood's lamp examination to detect vitiligo were conducted. In all those with vitiligo, the type of vitiligo was noted. Statistical Analysis Used: Data were analyzed using SPSS software version 20.0. Comparison between the presence of vitiligo in cases and controls was done using Chi-square test with P = 0.05 for significance. Results: Vitiligo was seen in 12% of cases and 6% of control group which was statistically significant (P < 0.01). There was no significant difference between cases and controls with respect to type of vitiligo. Conclusions: Vitiligo can occur in Type 2 diabetics as seen in our study and few other recent studies. The exact pathogenesis is not very clear and needs further consideration.

Abstract
Type 1 diabetes mellitus (T1DM) is one of the most common chronic diseases developing in childhood. The incidence of the disease in children increases for unknown reasons at a rate from 3 to 5% every year worldwide. The background of T1DM is associated with the autoimmune process of pancreatic beta cell destruction, which leads to absolute insulin deficiency and organ damage. Complex interactions between environmental and genetic factors contribute to the development of T1DM in genetically predisposed patients. The T1DM-inducing autoimmune process can also affect other organs, resulting in development of additional autoimmune diseases in the patient, thereby impeding diabetes control. The most common T1DM comorbidities include autoimmune thyroid diseases, celiac disease, and autoimmune gastritis; additionally, diabetes can be a component of PAS (Polyglandular Autoimmune Syndrome). The aim of this review is to assess the prevalence of T1DM-associated autoimmune diseases in children and adolescents and their impact on the course of T1DM. We also present suggestions concerning screening tests.
