    Several lines of evidence support the relevance of reactive oxygen species (ROS) in vitiligo, but the exact role of glycation and oxidation of macromolecules needs to be better addressed. To investigate the involvement of advanced oxidation protein products (AOPPs) and advanced glycation end-products (AGEs), we performed a case-control association study by spectrofluorimetry and spectrophotometry, in 47 patients with non-segmental generalized vitiligo and 47 age- and sex-matched controls. Significantly higher levels of both AOPPs (p vitiligo patients compared to healthy controls. In vitiligo patients, AGEs and AOPPs serum levels were directly associated with extension, duration of vitiligo, and disease activity. ROS, and in particular AGEs and AOPPs, could represent one of the main biomarkers to assess the onset and progression of vitiligo, due to the potential role as direct inducers of cell damage and also as autoimmunity triggers. Further longitudinal studies involving larger cohorts of patients are required to elucidate the role of oxidation products in the pathogenesis of vitiligo.

    IL-33 is a recently identified cytokine, encoded by the IL-33 gene, which is a member of the IL-1 family that drives the production of T-helper-2 (Th-2)-associated cytokines. Serum levels of IL-33 have been reported to be up-regulated in various T-helper (Th)-1/Th-17-mediated diseases, such as psoriasis, rheumatoid arthritis, and inflammatory bowel. To investigate whether cytokine imbalance plays a role in the pathogenesis of vitiligo, we performed a case-control association study by enzyme-linked immunosorbent assay of IL-33 in our patients. IL-33 serum levels were measured by a quantitative enzyme immunoassay technique in patients with non-segmental generalized vitiligo and compared with those of healthy controls. IL-33 serum levels in patients with vitiligo were significantly increased than those in healthy controls. There was a positive correlation of IL-33 serum levels with extension of vitiligo and disease activity. This study suggests a possible systemic role of IL-33 in the pathogenesis of vitiligo. Inhibiting IL-33 activity might be a novel therapeutic strategy in the treatment of autoimmune inflammatory disease, like vitiligo.

    In patients with vitiligo, the clinical and laboratory features of the disease may vary according to time of onset. This is addressed in the literature by only a few studies with conflicting results. The aim of this study was to determine the demographic and clinical features of patients with non-segmental vitiligo and to establish the association between vitiligo and autoimmune diseases with a focus on time of disease onset. A total of 224 vitiligo patients for whom complete medical records were available were evaluated retrospectively. Demographic data, scores on the Vitiligo Area Score Index (VASI), clinical features, vitiligo disease activity, repigmentation status, presence of any accompanying autoimmune disease, antinuclear antibody (ANA) titers, serum levels of glucose, thyroid-stimulating hormone (TSH), thyroxine (T4) hormone, anti-thyroid peroxidase (anti-TPO), and anti-thyroglobulin (anti-TG) were recorded. The prevalence of halo nevi was significantly higher (P vitiligo. © 2017 The International Society of Dermatology.

    Stable non-segmental vitiligo is often resistant to conventional therapies. The purpose of this study was to investigate the effect of three types of fractional lasers in the treatment of stable non-segmental vitiligo. Twenty patients were enrolled in the study. The vitiligo lesions of each patient were divided into four treatment parts, and all parts were treated with narrowband ultraviolet-B (NB-UVB). Three of the four parts were respectively treated with three types of fractional lasers (two ablative 10,600-nm CO 2 lasers and one non-ablative 1,565-nm laser), followed by topical betamethasone solution application. The treatment period lasted six months. Efficacy and satisfaction were respectively assessed by dermatologists and patients. The ablative CO 2 lasers, in combination with topical betamethasone solution and NB-UVB, achieved marked to excellent improvement on white patches assessed by dermatologists. Patients showed high satisfaction scores for the treatments. The non-ablative 1,565-nm fractional laser did not provide any further benefit in the treatment of vitiligo. No severe adverse events developed for any of the treatments. The treatment protocol with ablative CO 2 lasers, in combination with topical betamethasone solution and NB-UVB, was suitable for stable non-segmental vitiligo. For vitiligo, the ablative fractional CO 2 laser is more effective than the non-ablative fractional laser.

    Vitiligo is an acquired depigmenting disease with uncertain etiopathogenesis and the treatment modalities need to be consistently updated. To evaluate a triple-combination treatment with oral α-lipoic acid (ALA), betamethasone injection, and narrowband ultraviolet B (NB-UVB) on vitiligo. Patients with non-segmental and progressive vitiligo lesions were randomly assigned to two groups. The treatment group and the control group were respectively treated with oral ALA and placebo, in combination with betamethasone injection and NB-UVB. The effectiveness and adverse events were evaluated by investigators and patients before and after treatment. Fifty non-segmental progressive vitiligo patients were enrolled in the study. The treatment period was 6 months. In treatment group, over 40% patients achieved > 50% improvement and ≥ 5 satisfaction score by 3-month therapy (M3). This percentage increased to 90% at M6. Treatment group achieved better efficacy than control group at M3, while no difference was seen at M6. The combined treatment with oral ALA, betamethasone injection, and NB-UVB was effective and safe on non-segmental progressive vitiligo. ALA could accelerate the initial response of repigmentation.

    The present study was designed to evaluate the effect of combining fractional CO 2 laser with narrow-band ultraviolet B (NB-UVB) versus NB-UVB in the treatment of non-segmental vitiligo. The study included 20 patients with non-segmental stable vitiligo. They were divided into two groups. Group I received a single session of fractional CO 2 laser therapy on the right side of the body followed by NB-UVB phototherapy twice per week for 8 weeks. Group II received a second session of fractional CO 2 laser therapy after 4 weeks from starting treatment with NB-UVB. The vitiligo lesions were assessed before treatment and after 8 weeks of treatment by VASI. At the end of the study period, the vitiligo area score index (VASI) in group I decreased insignificantly on both the right (-2.6%) and left (-16.4%) sides. In group II, VASI increased insignificantly on the right (+14.4%) and left (+2.5%) sides. Using Adobe Photoshop CS6 extended program to measure the area of vitiligo lesions, group I showed a decrease of -1.02 and -6.12% in the mean area percentage change of vitiligo lesions on the right and left sides, respectively. In group II the change was +9.84 and +9.13% on the right and left sides, respectively. In conclusion, combining fractional CO 2 laser with NB-UVB for the treatment of non-segmental vitiligo did not show any significant advantage over treatment with NB-UVB alone. Further study of this combination for longer durations in the treatment of vitiligo is recommended.

    Non-segmental vitiligo (NSV) results from autoimmune destruction of melanocytes. The altered levels of various cytokines have been proposed in the pathogenesis of vitiligo. However, the exact immune mechanisms have not yet been fully elucidated. To investigate the role of epidermal and systemic cytokines in active and stable NSV patients. Serum levels of inflammatory cytokines were checked in 42 active and 30 stable NSV patients with 30 controls. The lesional, perilesional and normal skin sections were subjected to H&E staining. The mRNA expression of inflammatory cytokines and their respective receptors were assessed by quantitative PCR in lesional skin of both active and stable NSV skin. The MITF and IL-17A were immunolocalized in lesional, perilesional and normal skin tissue. Significant increase in the expression of inflammatory cytokines, IL-17A, IL-1β and TGF-β was observed in active patients, whereas no change was observed in stable patients. A marked reduction in epidermal thickness was observed in lesional skin sections. Significant increase in IL-17A and significant decrease in microphthalmia associated transcription factor (MITF) expression was observed in lesional and perilesional skin sections. Moreover, qPCR analysis showed significant alterations in the mRNA levels of IL-17A, IL-1β, IFN-γ, TGF-β and their respective receptors in active and stable vitiligo patient samples. Increased levels of IL-17A and IL-1β cytokines and decreased expression of MITF suggested a possible role of these cytokines in dysregulation of melanocytic activity in the lesional skin and hence might be responsible for the progression of active vitiligo.

    Resistant non-segmental vitiligo is difficult to be treated. Ablative erbium-YAG (Er:YAG) laser has been used in the treatment of vitiligo, but the ablation of entire epidermis frustrated the compliance of patients. The purpose of this study is to investigate the effects of fractional Er:YAG laser followed by topical betamethasone and narrow band ultraviolet B (NB-UVB) therapy in the treatment of resistant non-segmental vitiligo. The vitiligo lesions of each enrolled patient were divided into four treatment parts, which were all irradiated with NB-UVB. Three parts were, respectively, treated with low, medium, or high energy of Er:YAG laser, followed by topical betamethasone solution application. A control part was spared with laser treatment and topical betamethasone. The treatment period lasted 6 months. The efficacy was assessed by two blinded dermatologists. Treatment protocol with high energy of 1800 mJ/P of fractional Er:YAG laser followed by topical betamethasone solution and in combination with NB-UVB made 60% patients achieve marked to excellent improvement in white patches. The protocol with medium energy of 1200 mJ/P of laser assisted approximate 36% patients achieve such improvement. The two protocols, respectively, showed better efficacies than NB-UVB only protocol. However, fractional Er:YAG laser at low energy of 600 mJ/P did not provide such contributions to the treatment of vitiligo. The fractional Er:YAG laser in combination with topical betamethasone solution and NB-UVB was suitable for resistant non-segmental vitiligo. The energy of laser was preferred to be set at relatively high level.

    Vitiligo is a multifactorial disease in which, in each specific case of its manifestation, different mechanisms of its pathogenesis and different levels of melanin formation in the skin can be involved. Skin is one of the most metabolically active organs. Carrying out a number of vital functions (barrier, protective, respiratory, excretory, metabolic, immune, etc.), it needs microelementss. Of the 92 naturally occurring chemical elements, 81 are found in the human body. Lack of the vital elements, leads to the emergence of diseases, which are based on deficiency, excess or imbalance of micro- and macroelements in the body. To assess the elemental status of patients with various forms of vitiligo, fluorescent x-ray spectroscopy was used. The method has good informativeness, since the hair most fully reflects the level of content of both toxic and vital elements. According to the results obtained, in patients with segmental vitiligo, a slight decrease in the content of manganese and copper was detected in the hair. In the group of patients with non-segmental form of vitiligo, along with a significant decrease in the concentration of basic elements (on average from 20 to 50%) copper, manganese, selenium, zinc, there was an increase in the indices of such toxic elements as lead and cadmium. The data of multi-element hair analysis, as are confirmed by well-known information about the role of certain chemical elements in the pathogenesis of vitiligo, also allow us to make new assumptions about the possible relationship between the violation of the microelement balance of the organism with the emergence and peculiarity of the flow of various forms of vitiligo. The correct approach to understanding the mechanisms of the emergence of vitiligo, will allow to offer new effective schemes for the treatment of vitiligo.

    Inflammatory and immune processes can be triggered in vitiligo due to a decreased number of melanocytes and their anti-inflammatory effects. Because of the systemic nature of vitiligo, metabolic abnormalities such as insulin resistance and lipid profile disturbances as well as skin involvement may be observed in vitiligo. To investigate the association between metabolic syndrome and vitiligo. Case-control study. The demographic, clinical and laboratory features in the subjects were compared according to presence of vitiligo and metabolic syndrome [patients (n=63) vs. gender-age matched controls (n=65) and metabolic syndrome positive (n=38) vs. negative (n=90)]. A logistic regression analysis was also used. We identified metabolic syndrome in 24 (38.1%) subjects with vitiligo and 14 (21.5%) subjects without vitiligo (p=0.04). Active vitiligo, segmental vitiligo, an increased duration of vitiligo and an increased percentage in the affected body surface area were determined to be independent predictors of metabolic syndrome [activity of vitiligo: p=0.012, OR (95% CI)=64.4 (2.5-1672); type of vitiligo: p=0.007, OR (95% CI)=215.1 (4.3-10725.8); duration of vitiligo: p=0.03, OR (95% CI)=1.4 (1.1-2.0); percentage of affected body surface area: p=0.07, OR (95% CI)=1.2 (0.98-1.5)]. The risk of developing metabolic syndrome is increased in patients with vitiligo. The poor clinical features of vitiligo, such as active, extended and segmental vitiligo with an increased duration of time, are independent predictors for developing metabolic syndrome.

    Vitiligo is a chronic disease characterized by the appearance of achromic macules caused by melanocyte destruction. Surgical treatments with melanocyte transplantation can be used for stable vitiligo cases. To evaluate treatment response to the autologous transplantation of noncultured epidermal cell suspension in patients with stable vitiligo. Case series study in patients with stable vitiligo submitted to noncultured epidermal cell suspension transplantation and evaluated at least once, between 3 and 6 months after the procedure, to observe repigmentation and possible adverse effects. The maximum follow-up period for some patients was 24 months. Of the 20 patients who underwent 24 procedures, 25% showed an excellent rate of repigmentation, 50% good repigmentation, 15% regular, and 10% poor response. The best results were observed in face and neck lesions, while the worst in extremity lesions (88% and 33% of satisfactory responses, respectively). Patients with segmental vitiligo had a better response (84%) compared to non-segmental ones (63%). As side effects were observed hyperpigmentation of the treated area and the appearance of Koebner phenomenon in the donor area. Some limitations of the study included the small number of patients, a subjective evaluation, and the lack of long-term follow-up on the results. CONCLUSION: Noncultured epidermal cell suspension transplantation is efficient and well tolerated for stable vitiligo treatment, especially for segmental vitiligo on the face and neck.

    In recent years, despite some progress in the study of vitiligo many aspects of pathogenesis and treatment of this dermatosis remain unsolved or are highly controversial. It is believed that progression of disease is associated with a genetic predisposition, autoimmune processes and oxidative stress, but the concrete role of stress on the processes having place in the organism of vitiligo patients so far is not investigated. As we know, epiphysis is the main regulator of adaptation of the individual to the environment. An important product of secretion of the pineal gland is the hormone melatonin - a universal regulator of vital functions and biorhythms of the body. Psychoses, neuroses, depression, immunopathology are aspects of disturbances in circadian, seasonal and annual rhythms of the synthesis of this hormone. Clinical and experimental studies indicate that the hormone melatonin, which is one of the links in a stress defense mechanism of the body, has antioxidant and immunomodulatory properties. The purpose of this study was to determine plasma level of melatonin in the blood of vitiligo patients (with stress in anamnesis), depending on the clinical form and duration of the disease. 41 patients with vitiligo (16 with segmental and 25 with non-segmental form) with stress in anamnesis and duration of disease from several months to 20 years were under observation. The level of melatonin in the blood plasma was determined by ELISA (IBL - international - reagent), the results were expressed in units of pg/ml. According to the results of our study, 8 patients with segmental vitiligo had the normal level of plasma melatonin concentration (in the range of 20.2-31.1 pg/ml), in 2 cases - the level was near the norm (19.2 pg/ml). In the group of patients with non-segmental vitiligo, the level of melatonin was below the norm (12.5 pg/ml) and in 2 cases, the content of melatonin was very low - 4.05 pg / ml.

    Vitiligo, depigmenting disorder of the skin and mucous membranes, affects up to 1% of the population worldwide. It is classified into four major types: segmental, non-segmental, mixed, and unclassified type. Non-segmental vitiligo refers to non-dermatomal distribution of lesions, while dermatomal distribution of lesions is present in patients with segmental vitiligo. Segmental vitiligo can also follow Blaschko lines - pathways of epidermal cell migration and proliferation during the development of the fetus. Here, we present patient with segmental and non-segmental vitiligo following Blaschko lines with excellent therapeutic response to combined therapy. Prior to our report, a case of segmental and non-segmental vitiligo followed by Blaschko lines was never described, therefore we suggest the term "mixed vitiligo of Blaschko lines" to describe this entity. This is also a rare case in which 90% repigmentation was achieved in patient with segmental and nonsegmental vitiligo following Blaschko lines in only 2 months of combined therapy. © 2016 Wiley Periodicals, Inc.

    Increased serum levels of certain immunologic markers including immunoglobulin G (IgG) anti-melanocyte/ vitiligo antibodies (V-IgG) and soluble interleukin-2 receptors (sIL-2R) are associated with augmented humoral and cellular immunity involved in melanocyte cytotoxicity during the active phase of non-segmental vitiligo. Recent reports have shown that, aspirin possesses a wide range of immunomodulatory and antioxidant properties. Therefore, the aim of the present study is to investigate the effect of long-term treatment of vitiligo patients with low-dose oral aspirin on serum V-IgG activity and sIL-2R concentration. The present study was carried out at the Vitiligo Unit, King Abdul-Aziz University Medical Center, Jeddah, Kingdom of Saudi Arabia between March and October 2003. Eighteen female and 14 male patients with a recent onset of non-segmental vitiligo were divided into 2 equal groups. One group received a daily single dose of oral aspirin (300 mg) and the second group received only placebo for a period of 12 weeks. Serum V-IgG activity and sIL-2R concentration were determined before and at the end of treatment period. The V-IgG activity was measured using cellular enzyme-linked immunosorbent assay (ELISA) following incubation of IgG antibodies with an adult cultured melanocytes. Serum sIL-2R concentration was measured using the highly sensitive quantitative sandwich ELISA utilizing a commercially available kit. As expected, the serum V-IgG activity and sIL-2R concentration of the active vitiligo patients (0.81 +/- 0.23 optical density (O.D.), 1428 +/- 510 pg/ml) were significantly increased compared with that of controls (0.27 +/- 0.1 O.D., 846 +/- 312 pg/ml; p<0.05, p<0.01). Aspirin-treated vitiligo patients showed significant decrease in serum V-IgG activity and sIL-2R concentration (0.32 +/- 0.08 O.D., 756 +/- 216 pg/ml) compared with that of placebo-treated patients (0.83 +/- 0.19 O.D., 1327 +/- 392 pg/ml; p<0.01).

    Full Text Available O vitiligo é doença de pele de causa desconhecida que acomete cerca de 1% da população, comprometendo de modo semelhante homens e mulheres, preferencialmente entre 10 e 30 anos de idade. Alguns fatores precipitantes para essa doença são: estresse físico e emocional, traumas mecânicos e substâncias químicas, como derivados do fenol. Doenças auto-imunes, principalmente as tireoidianas, podem estar associadas ao vitiligo. Novas terapias têm sido propostas, como o uso de imunomoduladores tópicos, aliadas àquelas já consolidadas, como os psoralenos e os corticosteróides; o sucesso terapêutico, entretanto, está estritamente relacionado à qualidade da relação médico/paciente.Vitiligo is a skin disease of unknown etiology that affects 1% of the population. It affects both sexes equally and the mean age at onset is between 10 and 30 years. Some of the factors involved are: emotional or physical stress, mechanical trauma, chemicals such as phenol and certain diseases. Autoimmune diseases, especially of thyroid origin, may be linked to vitiligo. New and emerging therapies have been proposed such as topical immunomodulators, allied to traditional therapies with psoralen and steroids. The most important factor in the therapeutic success depends on the doctor and patient relationship.

    Full Text Available Introduction : Vitiligo is an acquired, idiopathic disorder characterized by circumscribed depigmented macules and patches, which affects approximately 0.1–2% of the general population worldwide. Zinc is an essential trace element that is necessary for growth and development at all stages of life. Some studies have reported an association between serum zinc levels and vitiligo. Aim : To measure the serum zinc level in patients with vitiligo compared to healthy subjects. Material and methods : One hundred patients with vitiligo and 100 healthy controls were referred to our clinic. The two groups were matched for age and sex. Atomic absorption spectrophotometry was used to measure serum zinc levels. The statistical analysis was performed using SPSS software. Results : The mean serum level of zinc in vitiligo patients and controls was 80.11 ±17.10 µg/dl and 96.10 ±16.16 µg/dl, respectively. The serum zinc level in patients with vitiligo was significantly lower than in healthy controls (p = 0.0001. Conclusions : The results of our study revealed a significant association between vitiligo and serum zinc levels. A relative decrease in the serum zinc level in vitiligo patients can highlight the role of zinc in the pathogenesis of vitiligo, and large-scale studies need to be conducted to confirm these findings and assess the effect of oral zinc supplements in patients with low zinc levels.

    In the etiopathogenesis of vitiligo, the role of suppressor cytokines, such as transforming growth factor-β (TGF-β) and interleukin-10 (IL-10), associated with regulatory T-cells (Treg) is not completely known. In this study, the role of Treg-cell functions in the skin of patients with nonsegmental vitiligo was investigated. Lesional and nonlesional skin samples from 30 adult volunteers ranging in age from 18 to 36 years with nonsegmental vitiligo were compared with normal skin area excision specimens of 30 benign melanocytic nevus cases as controls. All samples were evaluated staining for forkhead box P3 (Foxp3), TGF-β, and IL-10 using the standardized streptavidin-biotin immunoperoxidase immunohistochemistry method. Foxp3 expression was lower in lesional vitiligo skin specimens compared to controls; it was also lower in lesional vitiligo specimens than nonlesional vitiligo specimens. IL-10 levels were lower in lesional vitiligo specimens compared to the controls, whereas IL-10 expression was significantly lower in lesional specimens compared with nonlesional specimens. TGF-β expression was higher in both lesional and nonlesional skin specimens of patients with vitiligo compared to controls. TGF-β expression was lower in lesional skin specimens than nonlesional skin specimens. In addition, there was no significant correlation between Foxp3 expression with TGF-β and IL-10 expressions in lesional skin specimens in the vitiligo group. In this study, results supporting the contribution of Treg cells and IL-10 deficiency to the autoimmune process were obtained. Therefore, future studies are necessary to demonstrate the definitive role of Treg-cell functions in the etiopathogenesis of vitiligo. © 2017 The International Society of Dermatology.

    Quality of life is defined by the World Health Organization as "individuals' perceptions of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns." Often overlooked in the past, it is nowadays considered, in a more holistic view of medicine, a decisive factor to understand the impact of diseases and improve the quality of medical care. Such evaluation is particularly relevant for dermatological diseases, because visibility of the lesions can significantly affect self-esteem and social relationships. Vitiligo represents an emblematic case: often disfiguring and located in visible areas, confused in the past (and, in many world regions, even in the present) with leprosy, often perceived by physicians as a harmless, purely cosmetic problem, it significantly decreases the quality of life of affected persons. After a brief overview on definition, usefulness and methods for the assessment of quality of life, the authors examine the peculiarities of its relationship with skin diseases, particularly vitiligo. The state of the art of knowledge and research in this field is presented, together with data showing usefulness and positive results of a multidisciplinary approach, which adequately keeps into account perceived quality of life, on patient's satisfaction, adherence to treatment protocols and, ultimately, better outcome of treatments. In this context, an important role can be played by support communities, groups of patients and dedicated associations and societies, connected through modern communication networks like the Internet. © 2012 Wiley Periodicals, Inc.

    Limited studies have shown that treatment of cells with aspirin modulates their cytokine production. Consequently, the aim of the present study is to investigate the pattern of important proinflammatory cytokines production by stimulated peripheral blood mononuclear cells (PBMC) from patients with active vitiligo following long-term treatment with low-dose oral aspirin. The study was conducted at the Vitiligo Unit, King Abdul-Aziz University Medical Center, Jeddah, Kingdom of Saudi Arabia between March and October 2003. Thirty-two patients (18 females and 14 males) with non-segmental vitiligo were divided into 2 equal groups, one group received a daily single dose of oral aspirin (300 mg) and the other group received placebo for a period of 12 weeks. The concentrations of interleukin (IL)-1beta, IL-6, IL-8 and tumor necrosis factor-alpha (TNF-alpha) were determined in the supernatant of isolated cultured PMBC after being stimulated with bacterial lipopolysaccharide (LPS), before the start of aspirin treatment and at end of treatment period. Cytokine levels were measured using the quantitative sandwich enzyme-linked immunosorbent assay (ELISA) technique, utilizing commercially available kits. The proinflammatory cytokine production by the PBMC of patients with active vitiligo was significantly increased compared to normal controls. Thus, the relative percentage increase in the production of IL-1beta, IL-6, IL-8 and TNF-alpha was: 39.4%, 110.5% (p<0.05), 91.5% (p<0.01), and 37% (p<0.05). At the end of treatment, proinflammatory cytokine production in the aspirin-treated group of active vitiligo patients was significantly decreased compared to the placebo group. Thus, the relative percentage decrease in the production of IL-1beta IL-6, IL-8 and TNF-alpha was: 42.5%, 45.2% (p<0.05), 30.8% (p<0.01), and 50.6% (p<0.05). The vitiligo activity was arrested in all aspirin-treated patients, while 2 patients demonstrated significant repigmentation.Chronic administration of

    Background It was previously thought that persons with genetic predispositions to vitiligo develop the condition after exposure to various precipitating environmental factors. However, in many cases, the aggravating factors of vitiligo have not been clearly identified. Objective To identify the aggravating factors of vitiligo in the working environment and daily life. Methods A total of 489 vitiligo patients were recruited from 10 institutions in South Korea; patients were provided with a questionnaire about environmental factors and behavior patterns in the workplace and in daily life, and their association with vitiligo. Results Ninety-five of the 470 enrolled patients (20.2%) answered that environmental risk factors in daily life and in the workplace affected the development of vitiligo. The most frequently attributed causes were trauma and burn (13.6%), followed by sunlight (12.8%), stress (12.8%), cleaning products/disinfectant/chemicals (4.9%), and hair dye (2.1%). Conclusion Vitiligo of the hand and foot was associated with frequent exposure to aggravating materials and overexposure to sunlight, along with frequent trauma of these areas, all of which could be considered important risk factors of vitiligo. The development of vitiligo could potentially be controlled through the early detection of aggravating factors. PMID:24966635

    Few large-scale studies have quantified the burden of comorbid autoimmune diseases in patients with vitiligo. We sought to determine the prevalence of comorbid autoimmune diseases in patients with vitiligo. We conducted a manual chart review on a cohort of 1873 patients with vitiligo seen between January 2002 and October 2012 at the Henry Ford Health System in Detroit, MI. Patients were excluded if they had fewer than 2 dermatology notes (N = 595) or if they were never given a diagnosis of vitiligo by a dermatologist (N = 180). Of 1098 patients with vitiligo, nearly 20% had at least 1 comorbid autoimmune disease. Compared with the general US population, we found a higher prevalence of thyroid disease (12.9%, P vitiligo. We observed a high prevalence of comorbid autoimmune diseases in patients with vitiligo and report several new associations. Copyright © 2015 American Academy of Dermatology, Inc.

    Vitiligo is a common acquired depigmentation disorder. Previous studies have shown that vitiligo is associated with a variety of autoimmune disorders. However, a large-scale epidemiological study focused on comorbid rheumatic disorders has not been undertaken. To clarify the associations between vitiligo and various rheumatic disorders, we performed a cross-sectional study using data from the Korean National Health Insurance claims database. Between 2009 and 2013, totals of 86 210 patients with vitiligo and 172 420 age- and sex-matched controls without vitiligo were enrolled in this study. Vitiligo patients were found to be at increased risk of systemic lupus erythematosus, systemic sclerosis, Sjögren's syndrome and rheumatoid arthritis, but no significant association was found between vitiligo and dermatomyositis/polymyositis, Behçet's disease or ankylosing spondylitis. Subgroup analysis showed an increased risk of dermatomyositis/polymyositis in male and ankylosing spondylitis in female vitiligo patients. The risks of dermatomyositis/polymyositis or ankylosing spondylitis were higher in young vitiligo patients. Our study confirms a significant association between vitiligo and rheumatic disorders. Differences in comorbid rheumatic disorders by age group and sex suggest the need for patient-specific approaches. Careful consideration of rheumatic disorders is required for the proper management of comorbidities in vitiligo patients. © 2017 Japanese Dermatological Association.

    Full Text Available Background: Vitiligo has a special significance in Indian patients both because depigmentation is obvious on darker skin and the enormous stigma associated with the disease in the culture. Aims: This study was carried out to determine the beliefs about causation, aspects of the disease that cause concern, medical, and psychosocial needs of the patients, expectation from treatment and from the treating physician, and effects of disease on the patient′s life. Methods: Semi-structured interviews were conducted in 50 patients with vitiligo. Purposive sampling was used to select subjects for the study. Each interview was recorded on an audio-cassette and transcripts were analyzed to identify significant issues and concerns. Results: Patients had a range of concerns regarding their disease such as physical appearance, progression of white patches onto exposed skin and the whole body, ostracism, social restriction, dietary restrictions, difficulty in getting jobs, and they considered it to be a significant barrier to getting married. The condition was perceived to be a serious illness. Stigma and suicidal ideation was reported. While there were several misconceptions about the cause of vitiligo, most patients did not think their disease was contagious, heritable or related to leprosy. Multiple medical consultations were frequent. Complete repigmentation was strongly desired, but a lesser degree of repigmentation was acceptable if progression of disease could be arrested. The problems were perceived to be more severe in women. The disease imposed a significant financial burden. Conclusion: Addressing psychosocial factors is an important aspect of the management of vitiligo, particularly in patients from communities where the disease is greatly stigmatizing.

    The use of anti-programmed cell death (PD)-1 therapies in metastatic tumors is associated with cutaneous side effects including vitiligo-like lesions. We sought to characterize clinically and biologically vitiligo-like lesions occurring in patients receiving anti-PD-1 therapies by studying a case series of 8 patients with metastatic tumors and 30 control subjects with vitiligo. Eight patients receiving anti-PD-1 therapies with features of vitiligo-like lesions seen in our department were recruited. Clinical features and photographs were analyzed. For some patients, skin and blood samples were obtained. Results were compared with the vitiligo group. All patients developed lesions localized on photoexposed areas with a specific depigmentation pattern consisting of multiple flecked lesions without Koebner phenomenon. In contrast to vitiligo, patients receiving anti-PD-1 therapies who developed vitiligo-like lesions did not report any personal or family histories of vitiligo, thyroiditis, or other autoimmune disorders. Analysis of blood and skin samples revealed increased C-X-C motif ligand 10 levels in serum of patients developing vitiligo-like lesions, associated with skin infiltration of CD8 T-cells expressing C-X-C motif receptor 3 and producing elevated levels of interferon-γ and tumor necrosis factor-alfa. This cross-sectional study concerned a single center. Clinical and biological patterns of vitiligo-like lesions occurring in patients receiving anti-PD-1 therapies differ from vitiligo, suggesting a different mechanism.

    The pathophysiology of vitiligo is becoming increasingly clarified. In non-segmental vitiligo, early factors include activation of innate immunity, inflammasome activation, oxidative stress, and loss of melanocyte adhesion. Nonetheless, the main mechanism leading to non-segmental vitiligo involves an immune-mediated destruction of melanocytes. Anti-melanocyte-specific cytotoxic T cells exert a central role in the final effector stage. Genetic research revealed a multi-genetic inheritance displaying an overlap with other autoimmune disorders. However, some melanocyte-specific genes were also affected. Segmental vitiligo carries a different pathogenesis with most evidence indicating a mosaic skin disorder. Current management includes topical corticosteroids and immunomodulators. Narrow-band ultraviolet B can be used in patients not responding to topical treatment or in patients with extensive disease. Pigment cell transplantation offers an alternative for the treatment of segmental vitiligo or stable non-segmental lesions. Recent findings have revealed new targets for treatment that could lead to more efficient therapies. Targeted immunotherapy may halt the active immune pathways, although combination therapy may still be required to induce satisfying repigmentation. A recently established core set of outcome measures, new measurement instruments, and biomarker research pave the way for future standardized clinical trials.

    There is scarce literature connecting vitiligo and primary open angle glaucoma (POAG). Most literature reports that secondary complications are a direct consequence of corticosteroid treatment of vitiligo. In this study, we aimed to investigate the prevalence of ocular problems in patients with vitiligo and to determine its association with periorbital topical corticosteroid use. A cross-sectional study was carried out on 90 patients with vitiligo. The Vitiligo European Task Force questionnaire was completed for each patient. A control group comprising 90 healthy individuals who did not have vitiligo and who were matched on age and gender was used for comparison. A complete ophthalmologic examination was performed. A family history of glaucoma and the use of topical steroids were recorded. Two (2/90, 2.2%) of the patients with vitiligo had glaucoma compared with none of the individuals in the control group (P = .25). Nineteen of the 90 patients with vitiligo used periorbital steroids, and of these patients, 10.5% (2/19) developed glaucoma. The duration of periorbital corticosteroid use was 4.50 ± 2.1 years. Eighty-nine percent (17/19) of the vitiligo patients who applied the potent topical corticosteroid (class I) clobetasol propionate to the periorbital area did not develop glaucoma. In contrast, glaucoma was not observed in 79% (71/90) of the vitiligo patients who did not use steroids. Cataract, uveitis, or fundus problems were not observed in either group. The study suggests that patients who have vitiligo and use topical steroids periorbitally do not have an increased risk of glaucoma or cataracts. Future studies that have a larger sample size and use a detailed steroid use protocol are needed. © The Author(s) 2015.

    The loss of melanocytes in vitiligo is mainly attributed to defective autoimmune mechanisms and lately autoinflammatory mediators have become more emphasized. Among these, a number of class II cytokines and their receptors have displayed altered expression patterns in vitiligo. Thus, we selected 30 SNPs from the regions of respective genes to be genotyped in Estonian case-control sample (109 and 328 individuals, respectively). For more precise analyses, patients were divided into subgroups based on vitiligo progression activity, age of onset, sex, occurrence of vitiligo among relatives, extent of depigmented areas, appearance of Köbner's phenomenon, existence of halo nevi, occurrence of spontaneous repigmentation, and amount of thyroid peroxidase antibodies. No associations appeared in whole vitiligo group. In subgroups, several allelic and haplotype associations were found. The strongest involved SNPs rs12301088 (near IL26 gene), that was associated with familial vitiligo and existence of halo nevi, and rs2257167 (IFNAR1 gene), that was associated with female vitiligo. Additionally, haplotypes consisting of rs12301088 and rs12321603 alleles (IL26-IL22 genes), that were associated with familial vitiligo and existence of halo nevi. In conclusion, several genetic associations with vitiligo subphenotypes were revealed and functional explanations to these remain to be determined in respective studies. Copyright © 2016.

    Oxidative stress is known to be involved in the pathogenesis of autoimmune diseases such as vitiligo. Evidence suggests that the human mitochondrial DNA copy number (mtDNAcn) is vulnerable to damage mediated by oxidative stress. The purpose of this study was to examine and compare peripheral blood mtDNAcn and oxidative DNA damage byproducts (8-hydroxy-2-deoxyguanosine; 8-OHdG) in patients with vitiligo and healthy controls (HCs). The relative mtDNAcn and the oxidative damage (formation of 8-OHdG in mtDNA) of each sample were determined by real-time quantitative PCR. Blood samples were obtained from 56 patients with vitiligo and 46 HCs. The mean mtDNAcn and the degree of mtDNA damage were higher in patients with vitiligo than in HCs. These data suggest that increase in mtDNAcn and oxidative DNA damage may be involved in the pathogenesis of vitiligo. © 2017 British Association of Dermatologists.

    Vitiligo is the most common depigmentation disorder of the skin. Oxidative stress is implicated as one of the probable events involved in vitiligo pathogenesis possibly contributing to melanocyte destruction. Evidence indicates that certain genes including those involved in oxidative stress and melanin synthesis are crucial for development of vitiligo. This study evaluates the oxidative stress status, the role of catalase (CAT) and catechol-O-Methyltransferase (COMT) gene polymorphisms in the etiology of generalized vitiligo in Egyptians. Total antioxidant capacity (TAC) and malondialdehyde (MDA) levels as well as CAT exon 9 T/C and COMT 158 G/A polymorphisms were determined in 89 patients and 90 age and sex-matched controls. Our results showed significantly lower TAC along with higher MDA levels in vitiligo patients compared with controls. Meanwhile, genotype and allele distributions of CAT and COMT polymorphisms in cases were not significantly different from those of controls. Moreover, we found no association between both polymorphisms and vitiligo susceptibility. In conclusion, the enhanced oxidative stress with the lack of association between CAT and COMT polymorphisms and susceptibility to vitiligo in our patients suggest that mutations in other genes related to the oxidative pathway might contribute to the etiology of generalized vitiligo in Egyptian population.

    We aimed to analyze the electrophysiologic function and morphology of macula in vitiligo patients. Seventeen patients with vitiligo and 11 healthy subjects were studied. All participants underwent multifocal electroretinography (mfERG) and spectral domain optical coherence tomography (SD-OCT) evaluations. The mfERG (P1 mfERG responses central and peripheral) and retinal layer segmentation parameters (nine ETDRS subfields) were compared in vitiligo and control groups. The mean P1 response amplitudes were significantly decreased in central and peripheral rings of the fovea in patients with vitiligo compared with controls (p = 0.002 and p = 0.006, respectively). There was a tendency toward a prolonged mean implicit time for both central and peripheral in patients with vitiligo compared to controls, however, with no statistical significance (p = 0.453 and p = 0.05, respectively). There was no statistically significant difference in all retinal layers thickness between two groups. In patients with vitiligo, while photoreceptor segment preserved in SD-OCT, mfERG reduced showing potential decline in central retinal function. This study showed a potential decline in central retinal function in patients with vitiligo even if they have normal fundus appearance and SD-OCT findings.

    Vitiligo is a multi-factorial pigmentary skin disorder. Recently, the importance of emotional and psychological issues is proposed in incidence, progression, relapse and remission of vitiligo. There are limited studies conducted in developing countries, which assess life quality of patients with vitiligo. The aim of this study was the application and evaluation of a disease-specific quality of life index in Iranian patients, for the first time. This cross-sectional biphasic study was conducted on 25 patients as a pilot and another 173 patients as the main study group, in Razi Hospital, Tehran, Iran, 2013-2014. Persian version of Vitiligo Quality of Life index (VitiQoL) was developed with backward-forward method. Based on the pilot study, the validity and reliability were assessed. The Vitiligo Area and Score Index (VASI), VitiQoL, and their relationship, demographic and clinical characteristic of patients were measured. The Mean and standard deviation of the VitiQoL score was 30.5 ± 14.5 (range 0-60 in Persian version). There was a significant relationship between VASI score and VitiQoL (p = 0.015, r = 0.187). Confirmatory factor analysis revealed three important factors within VitiQoL: participation limitation, stigma, and behavior. In subscale analysis based on behavior factor, female patients had poorer quality of life (p = 0.02). Concomitant psychiatric problems, e.g. anxiety and depression, were not associated with QOL; however, they were near to being meaningful (p = 0.06, r = 0.14). VitiQoL is a valid index in estimating life quality of vitiligo patients and has proper relation to disease severity. Focusing on patient's life quality is an important entity in the management of vitiligo patients; relevant supportive group-based consultations and therapies are also important arms when approaching vitiligo.

Although the etiology of vitiligo is unknown, over the last few years, substantial data from clinical research has greatly supported the ′Autoimmune theory′ and this is supported by the frequent association of vitiligo with disorders that have an autoimmune origin, including Hashimoto′s thyroiditis, Graves disease, type 1 insulin-dependent diabetes mellitus, and Addison′s disease. As cytokines are important mediators of immunity, there is evidence to suggest that they play a major role in the pathogenesis of autoimmune diseases. Aim: Keeping this in view we have assayed sera for cytokine IL-6, IL-2, Tumor necrosis factor (TNF-α, and IFNγ in 80 cases of vitiligo and compared it with healthy subjects, in order to find out whether they play a role in the pathogenesis of vitiligo or not. Materials and Methods: Serum IL-6, IL-2, TNF-α, and IFNγ were done by the indirect enzyme linked immunosorbent assay (ELISA. Results: The mean serum IL-6 and IL-2 levels in the patient group were significantly higher when compared with those of the normal controls. The mean serum IFNγ level in patients with vitiligo was significantly lower than that in the control group. There was no significant difference in the serum level of TNF-α between vitiligo and healthy controls. Conclusion : An increase in the production of proinflammatory cytokines such as IL-6 and IL-2 in vitiligo patients may play an important role in melanocytic cytotoxicity. Thus, we speculate that the cytokine production of epidermal microenvironment may be involved in vitiligo.

    For the treatment of vitiligo, narrowband UVB (NBUVB) light is considered the most effective for nonsegmental vitiligo, while excimer laser treatment is commonly used for localized vitiligo. However, treatment areas may potentially be missed with excimer laser treatment. We aimed to evaluate the effect of combinational treatment with NBUVB light and excimer laser on vitiligo. All patients were first treated with NBUVB; excimer laser was then applied in conjunction with NBUVB phototherapy due to a slow response or no further improvement with continuous NBUVB treatment alone. To minimize adverse effects, a fixed dose of NBUVB was administered, and the dose of excimer laser was increased based on patient response. Among 80 patients, 54 patients showed responses after combination with excimer laser; however, 26 patients (32.5%) showed no remarkable change after combination therapy. Of the 26 patients who showed no further response, 12 patients (46.1%) presented with vitiligo on the acral areas, which are known to the least responsive sites. Our study suggests that combined treatment of NBUVB and excimer laser in vitiligo may enhance the treatment response without remarkable side effects, therefore might also increase the compliance of the patients to the treatment. © 2015 John Wiley & Sons A/S.

    To investigate ocular manifestations in patients with vitiligo by multimodal imaging, including optical coherence tomography (OCT), color fundus photography, and fundus autofluorescence (FAF). In this prospective, observational clinical study, vitiligo patients underwent ophthalmologic and dermatologic clinical assessment and imaging by spectral-domain OCT, FAF, and color fundus imaging. Ocular echography was performed as indicated. Statistical analysis was performed using paired T test and Pearson correlation. A total of 61 eyes of 31 vitiligo patients were examined. Ocular findings consisted of choroidal nevi (n = 10, 32%), of which four (40%) were bilateral; two patients (6.5%) had a prominent choroidal pattern, two (6.5%) had hypopigmentary retinal pigment epithelium (RPE) lesions, and one (3.2%) had peripapillary atrophy of the RPE. Choroidal nevi were demonstrated only in eyes of patients with generalized vitiligo and were more common with upper body involvement (p = 0.02) and more prevalent in women (p = 0.02). Hypopigmentary lesions were detected in two patients and demonstrated on OCT as RPE atrophy and as photoreceptor/RPE changes. In this case series, vitiligo patients had a higher rate of choroidal nevi than previously reported. The hypopigmentary vitiliginous fundus lesions were depicted on OCT as photoreceptor and RPE atrophy. These findings may suggest the advisability of regular ocular monitoring for vitiligo patients.

    Background: Vitiligo is one of the most common skin disorders. However, the etiology of vitiligo is still unknown. Current hypotheses discuss autoimmune, autotoxic and neuronal mechanisms. Here we report the case of radiation-induced depigmentation of the skin of a patient with Hodgkin's disease and 25-year history of vitiligo. Patient and Method: We compared possible differences in skin color, skin moisture, microcirculation and skin elasticity between normal skin and skin exhibiting persistent depigmentation in a 37-year-old patient 40 months after completion of external beam radiotherapy. Results: Colormetrically we found a dose-dependent decrease of the red/green and yellow/blue saturation combined with an overall increase in brightness in depigmented skin when compared with normal skin. This was in agreement with a loss of melanocytes in vitiligo. Depigmentation was complete in areas receiving 40 Gy. Areas which received 30 Gy showed depigmentation only if the skin dose was increased by the loss of depth of the build-up dose region in areas with direct contact with the irradiation table. We could not show any change in skin moisture, microcirculation or skin elasticity. Conclusions: Complete radiation-induced depigmentation of skin from patients suffering from vitiligo is a side effect of radiation therapy. Patients should be informed about this side effect by the radiooncologist. Preventing the loss of depth of the build-up dose region might improve the cosmetic results of radiation therapy in patients with history of vitiligo. (orig.)

    Cosmetic camouflage is important for patients with vitiligo vulgaris. However, few studies have investigated its benefit for vitiligo patients. To analyze the psychological effects on patients with vitiligo vulgaris by camouflage lessons performed in vitiligo clinics in Kyoto University Hospital and Fukui Red Cross Hospital, Dermatological Life Quality Index (DLQI) questionnaires were collected before and 1 month after camouflage lessons. Patients with vitiligo vulgaris, who visited our clinics in 2008 and had never experienced camouflage, were enrolled in this study. They took camouflage lessons and continued subsequent self-camouflage for 1 month. Control patients took no lessons and no camouflage. Camouflage improved the scores of DLQI when compared with those without camouflage (P = 0.005). Camouflage improved DLQI scores from 5.90 to 4.48. In DLQI subcategories, camouflage lessons improved a subcategory of "symptoms and feelings" (P = 0.0037). These data supported the idea that camouflage for patients with vitiligo not only covers the white patches but also improves their quality of life.

    Vitiligo is occasionally seen in melanoma patients. Although several studies indicate a correlation between vitiligo occurrence and clinical response in melanoma patients receiving immunotherapy, most studies have included heterogeneous patient and treatment settings. The aim of this study is to investigate the correlation between the occurrence of vitiligo and clinical benefit of nivolumab treatment in advanced melanoma patients. We retrospectively reviewed unresectable stage III or IV melanoma patients treated with nivolumab. Of 35 melanoma patients treated with nivolumab, 25.7% (9/35) developed vitiligo during treatment. The time from the start of nivolumab treatment to occurrence of vitiligo ranged 2-9 months (mean, 5.2). Of nine patients who developed vitiligo, two (22.2%) had a complete response to nivolumab and two (22.2%) had a partial response. The objective response rate was significantly higher in patients with vitiligo than in patients without vitiligo (4/9 [44.4%] vs 2/26 [7.7%]; P = 0.027). The mean time to vitiligo occurrence in patients achieving an objective response was significantly less than that in patients who showed no response (3.1 vs 6.8 months, P = 0.004). Vitiligo occurrence was significantly associated with prolonged progression-free and overall survival (hazard ratio, 0.24 and 0.16; 95% confidence interval, 0.11-0.55 and 0.03-0.79; P = 0.005, and 0.047, respectively). At the 20-week landmark analysis, however, vitiligo was not associated with a statistically significant overall survival benefit (P = 0.28). The occurrence of vitiligo during nivolumab treatment may be correlated with favorable clinical outcome. © 2016 Japanese Dermatological Association.

    Nivolumab, an anti-programmed cell death-1 protein monoclonal antibody, is effective for treating patients with late-stage non-small-cell lung cancer. Immune checkpoint inhibitors such as nivolumab induce various kinds of immune-related adverse events, including vitiligo. Vitiligo has been reported in patients with melanoma but not lung cancer. We describe a 75-year-old man with lung adenocarcinoma, stage 4 with pleural and pericardial effusion, that progressed after first-line chemotherapy. Subsequently, he was treated with nivolumab as second-line therapy. After 6days of administering nivolumab, he developed vitiligo suddenly on the trunk of his body. Except for vitiligo, his physical examination was normal, and treatment with nivolumab was well tolerated. Therefore, this treatment was continued without further development or expansion of vitiligo. A computed tomography scan showed a reduction in the size of the lung nodule and stabilization of the pleural and pericardial effusion. This is the first case of vitiligo associated with the use of nivolumab in a patient with lung adenocarcinoma. Copyright © 2017. Published by Elsevier B.V.

    During the 2011 International Pigment Cell Conference (IPCC), the Vitiligo European Taskforce (VETF) convened a consensus conference on issues of global importance for vitiligo clinical research. As suggested by an international panel of experts, the conference focused on four topics: classification and nomenclature; definition of stable disease; definition of Koebner's phenomenon (KP); and 'autoimmune vitiligo'. These topics were discussed in seven working groups representing different geographical regions. A consensus emerged that segmental vitiligo be classified separately from all other forms of vitiligo and that the term 'vitiligo' be used as an umbrella term for all non-segmental forms of vitiligo, including 'mixed vitiligo' in which segmental and non-segmental vitiligo are combined and which is considered a subgroup of vitiligo. Further, the conference recommends that disease stability be best assessed based on the stability of individual lesions rather than the overall stability of the disease as the latter is difficult to define precisely and reliably. The conference also endorsed the classification of KP for vitiligo as proposed by the VETF (history based, clinical observation based, or experimentally induced). Lastly, the conference agreed that 'autoimmune vitiligo' should not be used as a separate classification as published evidence indicates that the pathophysiology of all forms of vitiligo likely involves autoimmune or inflammatory mechanisms. © 2012 John Wiley & Sons A/S.

  15. Childhood vitiligo

    2012-01-01

    Full Text Available Childhood vitiligo is often encountered in dermatological practice. When present in infancy or early childhood, various nevoid and hereditary disorders are to be differentiated. In many cases, familial aggregation of the disease is seen and other autoimmune disorders may be associated. Segmental presentation is more common, and limited body surface area involvement is usual in this age group. Children with vitiligo often suffer from anxiety and depression because of their unusual appearance. Management of vitiligo in children is difficult as therapeutic options are restricted when compared to that in adult patients. Selection of treatment should be careful in these patients with the aim to achieve best results with minimal side effects as well as relieving patients′ and parents′ anxiety.

    Roshankumar A Patil

    2017-01-01

    Full Text Available Background: Vitiligo is a relatively common pigment disorder. Exacerbation or complete depigmentation within the radiation portals as a result of the Koebner phenomenon in patients with preexisting vitiligo has been reported in the literature. However, new-onset vitiligo triggered by radiation in patients without prior history of the disorder is a rare occurrence. Methods: The authors report one such occurrence in a breast cancer patient wherein the depigmentation remained localised within the radiotherapy target volume without generalisation. This young lady had received adjuvant radiotherapy to the right breast and ipsilateral supraclavicular fossa to a dose of 50 Gy in 25 fractions followed by 15 Gy in 6 fractions to the tumour bed. Discussion: The authors present a short review of the literature and discussion on the etiopathogenesis and therapeutic implication of the condition in cancer management. Conclusion: This rare occurrence highlights the importance of taking decision on radiotherapy on a case-to-case basis in patients known to have vitiligo as it has direct bearing on the ultimate cosmetic and psychological outcome. However, it is also equally important to be aware that radiation-induced depigmentation be a precursor of subsequent new-onset generalised vitiligo.

    Full Text Available Nonsegmental vitiligo is a depigmented skin disorder showing acquired, progressive, and depigmented lesions of the skin, mucosa, and hair. It is believed to be caused mainly by the autoimmune loss of melanocytes from the involved areas. It is frequently associated with other autoimmune diseases, particularly autoimmune thyroid diseases including Hashimoto's thyroiditis and Graves' disease, rheumatoid arthritis, type 1 diabetes, psoriasis, pernicious anemia, systemic lupus erythematosus, Addison's disease, and alopecia areata. This indicates the presence of genetically determined susceptibility to not only vitiligo but also to other autoimmune disorders. Here, we summarize current understanding of autoimmune pathogenesis in non-segmental vitiligo.

    Full Text Available Background and Aim: The aim is to measure and to compare the level of social participation experienced by vitiligo and psoriasis patients in their domestic and social life in an Indian context. Methods: A cross-sectional comparative study with a sample of 150 cases each of psoriasis and vitiligo, a total of 300 subjects. A detailed clinical assessment of these two conditions, including the extent of lesions on the affected body parts, socioeconomic status and participation levels in social and domestic lives, was done. Results: The result showed that, 17.3% of vitiligo patients participated minimally in domestic and social life, whereas 28% of psoriasis patients had this problem (P=0.027. Extreme participation restriction was observed only among psoriasis patients (2.7%. Psoriasis patients also faced significantly more restrictions in a number of day-to-day life situations such as, less confidence in learning and applying knowledge, difficulties in meaningfully participating in major life areas like, work, education and employment, and also in community, social and civic life (all three domains P<0.0001, to vitiligo patients. Conclusion: Both psoriasis and vitiligo patients suffered moderate to severe restriction while participating in their domestic and social life. Of these two groups, psoriasis patients faced significantly more restrictions in a number of day-to-day life situations. The Indian population of this study was predominantly dark-skinned and hypo-pigmentation as seen in vitiligo is much more noticeable than psoriatic red patches. However, the results showed that the component of hypo or hyperpigmentation of the skin is not the only factor leading to participation restrictions.

    Vitiligo is an acquired and progressive hypomelanotic disease that manifests as circumscribed depigmented patches on the skin. The aetiology of vitiligo remains unclear, but recent experimental data underline the interactions between melanocytes and other typical skin cells, particularly keratinocytes. Our previous results indicate that keratinocytes from perilesional skin show the features of damaged cells. Sirtuins (silent mating type information regulation 2 homolog) 1, well-known modulators of lifespan in many species, have a role in gene repression, metabolic control, apoptosis and cell survival, DNA repair, development, inflammation, neuroprotection and healthy ageing. In the literature there is no evidence for SIRT1 signalling in vitiligo and its possible involvement in disease progression. Here, biopsies were taken from the perilesional skin of 16 patients suffering from non-segmental vitiligo and SIRT1 signalling was investigated in these cells. For the first time, a new SIRT1/Akt, also known as Protein Kinase B (PKB)/mitogen-activated protein kinase (MAPK) signalling has been revealed in vitiligo. SIRT1 regulates MAPK pathway via Akt-apoptosis signal-regulating kinase-1 and down-regulates pro-apoptotic molecules, leading to decreased oxidative stress and apoptotic cell death in perilesional vitiligo keratinocytes. We therefore propose SIRT1 activation as a novel way of protecting perilesional vitiligo keratinocytes from damage. PMID:24410795

    Full Text Available Background: The etiology and pathophysiologic mechanism of vitiligo are still unclear. The relationship between increased oxidative stress due to the accumulation of radicals and reactive oxygen species and the associated changes in blood and epidermal component of vitiliginous skin have been reported many times. We investigated the possible changes of plasma malondialdehyde, glutathione, selenium, hydroxyproline and glutathione peroxidase activity levels in patients with vitiligo in order to evaluate the relationship between oxidative stress and etiopathogenesis of vitiligo. Materials and Methods: Plasma malondialdehyde, glutathione, hydroxyproline and glutathione peroxidase activity levels were measured by spectrophotometric methods, and HPLC was used for measurement of selenium concentrations. Results: Our results showed increased malondialdehyde, hydroxyproline and glutathione peroxidase activity levels in plasma of vitiligo group ( P < 0.05. Conclusion: Support of antioxidant system via nonenzymatic antioxidant compounds and antioxidant enzymes may be useful to prevent of melanocyte degeneration which occur due to oxidative damage in vitiligo.

Patients and Methods: We prospectively analyzed the clinical data of children with vitiligo presented to the dermatology derpartement at University Hospital – Fès for 5 years from May 2011 to May 2016. This study included 31 patients. All patients were assessed for the natural history, clinical characteristics, family history, and associated abnormalities of vitiligo. Results: Of the 31 children with vitiligo 9 (29,03% were boys and 21 (67.74% were girls. The mean age of onset of the vitiligo was 10 years. The mean duration of the disease was 38,9 weeks. The most common type of vitiligo was vitiligo vulgaris (49.5% followed by focal vitiligo (39%, acrofacial vitiligo (32%, and segmental vitiligo (16% The most frequent site of onset was the extremities followed by the head and the neck, then the trunk and the genitalia. Of the 31 children with vitiligo, 39% had a family history and 4 % had an antecedent of autoimmune diesease like le diabète, une thyroïdite, l’anémie et le psoriasis, retrouvé. Conclusion: Our children have a strong family history of vitiligo and they are developing the disease at a slightly older age compared with those of other studies; however, other epidemiologic features appear to be similar to those reported in the previously published studies.

    Vitiligo and albinism are two disorders of pigmentation that make the affected African highly visible and strikingly different from their peers. Both pose considerable management challenges, attract significant stigma and profound impairment of quality of life. To determine and compare psychiatric distress in vitiligo and albinism using the Hospital Anxiety and Depression Scale (HADS). Participants were 87 albinos and 102 vitiligo adult patients seen at an urban tertiary hospital in Nigeria between 2004 and 2009. Prevalence of psycho morbidity was 59% (60/102) in vitiligo compared with 26% (23/87) in the albinos. The mean anxiety score was estimated to be 2.55 points lower for albino patients (95% CI: 1.47 to 3.64), and the mean depression score 2.76 points lower (95% CI: 1.84 to 3.68), after adjustment for age, sex and marital status. However, significant differences were not observed when comparing the vitiligo patients with the subset of albino patients with skin cancer. Older patients had significantly higher anxiety and depression scores. Females had significantly higher anxiety scores (but not depression scores) compared to males. Genital involvement in vitiligo was significantly associated with anxiety but not depression. We found that the African with vitiligo suffers significantly higher psychiatric distress than the African albino on average. Clinical evaluation of these patients would be incomplete without assessment of their psycho morbidity. There is need for increased focus on cancer prevention strategies in the African albino. © 2013 European Academy of Dermatology and Venereology.

    Full Text Available Vitiligo is a disorder with profound heterogeneity in its aetio-pathophysiology. Angiotensin converting enzyme (ACE plays an important role in the physiology of the vasculature, blood pressure and inflammation. An insertion/deletion (I/D polymorphism of the ACE gene was reported be associated with the development of vitiligo.Our aim was to evaluate the ACE I/D polymorphism in vitiligo patients and controls. Our second aim was to find a possible association between ACE gene polymorphism and inflammatory mediators (as interleukin (IL-6 and/or cellular cytotoxicity induced by serum nitrite (as a breakdown product of the cytotoxic nitric oxide in vitiligo patients.This case-control study included 74 vitiligo patients and 75 apparently healthy controls. The distribution of ACE gene I/D genotype was investigated using PCR. Serum ACE, IL-6 and nitrite were measured by colorimetric method, ELISA and Griess assay respectively.The ACE allele frequency was significantly different between vitiligo patients and healthy controls (P = 0.026. However there was no significant difference between the ACE genotyping frequency in both groups (P = 0.115. There were statistically significant higher VIDA score (P = 0.007, and serum IL-6 (P < 0.001 in patients with the DD genotype when compared to other genotypes. Serum nitrite in patients with the DD genotype was significantly higher (P = 0.007 when compared to patients with II genotype. Serum levels of ACE, IL-6 and nitrite in vitiligo patients were statistically significantly higher than those in controls.As a conclusion, ACE gene polymorphism might grant susceptibility to develop vitiligo. Serum IL-6 and nitrite levels might have an important role in the pathogenesis of vitiligo. Targeting these two factors might have an implication in the treatment of some resistant cases.

  9. Survey and online discussion groups to develop a patient-rated outcome measure on acceptability of treatment response in vitiligo

    Science.gov (United States)

    2014-01-01

    Background Vitiligo is a chronic depigmenting skin disorder which affects around 0.5-1% of the world’s population. The outcome measures used most commonly in trials to judge treatment success focus on repigmentation. Patient-reported outcome measures of treatment success are rarely used, although recommendations have been made for their inclusion in vitiligo trials. This study aimed to evaluate the face validity of a new patient-reported outcome measure of treatment response, for use in future trials and clinical practice. Method An online survey to gather initial views on what constitutes treatment success for people with vitiligo or their parents/carers, followed by online discussion groups with patients to reach consensus on what constitutes treatment success for individuals with vitiligo, and how this can be assessed in the context of trials. Participants were recruited from an existing database of vitiligo patients and through posts on the social network sites Facebook and Twitter. Results A total of 202 survey responses were received, of which 37 were excluded and 165 analysed. Three main themes emerged as important in assessing treatment response: a) the match between vitiligo and normal skin (how well it blends in); b) how noticeable the vitiligo is and c) a reduction in the size of the white patches. The majority of respondents said they would consider 80% or more repigmentation to be a worthwhile treatment response after 9 months of treatment. Three online discussion groups involving 12 participants led to consensus that treatment success is best measured by asking patients how noticeable their vitiligo is after treatment. This was judged to be best answered using a 5-point Likert scale, on which a score of 4 or 5 represents treatment success. Conclusions This study represents the first step in developing a patient reported measure of treatment success in vitiligo trials. Further work is now needed to assess its construct validity and responsiveness to

    Full Text Available Vitiligo Vulgaris is a pigment disorder as the lack of skin pigmentation which its most prevalent cause is autoimmune. Vitamin D has various effects on the natural and acquired immune of the body because of its effectiveness on the T cells and B cells, macrophages and dendritic cells.The object of this study was assessment of the Vitamin D in patients with vitiligo vulgaris in dermatologic clinics in Qazvin in 2012. The 100 patients with Vitiligo were studied through a cross-sectional study. The required data were collected by the questionnaire (age, gender, job, family background, consumption of the dairies and vitamin D supplements, examination (type of skin and para clinical test (measurement of the serum 25-hydroxyvitamin D level. The 42 (42% and 58 (58% people of the population under study were respectively male and female. The mean age of the population under study was 28.7±1.17. The mean serum of 25-hydroxyvitamin D level was 42±24.14 which had a significance difference with a normal level (p<0.04. The mean serum 25-hydroxyvitamin D level among patients with Vitiligo had a significance difference with a normal level.

    Vitiligo is a disorder with profound heterogeneity in its aetio-pathophysiology. Angiotensin converting enzyme (ACE) plays an important role in the physiology of the vasculature, blood pressure and inflammation. An insertion/deletion (I/D) polymorphism of the ACE gene was reported be associated with the development of vitiligo. Our aim was to evaluate the ACE I/D polymorphism in vitiligo patients and controls. Our second aim was to find a possible association between ACE gene polymorphism and inflammatory mediators (as interleukin (IL)-6) and/or cellular cytotoxicity induced by serum nitrite (as a breakdown product of the cytotoxic nitric oxide) in vitiligo patients. This case-control study included 74 vitiligo patients and 75 apparently healthy controls. The distribution of ACE gene I/D genotype was investigated using PCR. Serum ACE, IL-6 and nitrite were measured by colorimetric method, ELISA and Griess assay respectively. The ACE allele frequency was significantly different between vitiligo patients and healthy controls (P = 0.026). However there was no significant difference between the ACE genotyping frequency in both groups (P = 0.115). There were statistically significant higher VIDA score (P = 0.007), and serum IL-6 (P ACE, IL-6 and nitrite in vitiligo patients were statistically significantly higher than those in controls. As a conclusion, ACE gene polymorphism might grant susceptibility to develop vitiligo. Serum IL-6 and nitrite levels might have an important role in the pathogenesis of vitiligo. Targeting these two factors might have an implication in the treatment of some resistant cases.

    Vitiligo is an idiopathic skin disease manifested by depigmented macules. It is characterised by melanocyte destruction, and redox imbalance is proposed to play a contributory role. The aim of this study was to analyze the effects of an ethanolic extract of Piper betle leaves on the generation of reactive oxygen species in erythrocytes sourced from vitiligo patients. The effect of Piper betle on the generation of reactive oxygen species in erythrocytes was measured by flow cytometry in patients with active and stable vitiligo versus healthy controls, using 5-(and-6)-chloromethyl-2'-7'-dichlorodihydrofluorescein diacetate. The generation of reactive oxygen species in erythrocytes was higher in patients with vitiligo (n = 23) compared to healthy controls (n = 18). The geometrical mean fluorescence channel was 23.05 ± 2.11 in patients versus 17.77 ± 1.79 in controls, P = 0.039. The levels of reactive oxygen species were higher in patients with active vitiligo. Treatment of erythrocytes with Piper betle in concentrations of 0.5 and 1.0 μg/ml significantly decreased the baseline levels of reactive oxygen species by 31.7% in healthy controls, and 47.6% and 44.3% in patients with active vitiligo, respectively. Piper betle effectively scavenged hydrogen peroxide, which was evident by a decrease in the geometrical mean fluorescence channel by 52.4% and 62.9% in healthy controls, and 45.0% and 57.0% in patients with active vitiligo. The study had a small sample size. Future studies should focus on evaluation of the antioxidant role of Piper betle at the lesional site. This pilot study indicates that patients with active vitiligo demonstrate enhanced generation of reactive oxygen species in erythrocytes, which was significantly reduced following ex vivo treatment with Piper betle.

    Summary During the 2011 International Pigment Cell Conference (IPCC), the Vitiligo European Taskforce (VETF) convened a consensus conference on issues of global importance for vitiligo clinical research. As suggested by an international panel of experts, the conference focused on four topics: classification and nomenclature; definition of stable disease; definition of Koebner’s phenomenon (KP); and ‘autoimmune vitiligo’. These topics were discussed in seven working groups representing different geographical regions. A consensus emerged that segmental vitiligo be classified separately from all other forms of vitiligo and that the term ‘vitiligo’ be used as an umbrella term for all non-segmental forms of vitiligo, including ‘mixed vitiligo’ in which segmental and non-segmental vitiligo are combined and which is considered a subgroup of vitiligo. Further, the conference recommends that disease stability be best assessed based on the stability of individual lesions rather than the overall stability of the disease as the latter is difficult to define precisely and reliably. The conference also endorsed the classification of KP for vitiligo as proposed by the VETF (history based, clinical observation based, or experimentally induced). Lastly, the conference agreed that ‘autoimmune vitiligo’ should not be used as a separate classification as published evidence indicates that the pathophysiology of all forms of vitiligo likely involves autoimmune or inflammatory mechanisms.

    The programmed-death-1 inhibitors selectively block programmed-death-1 interaction with its receptor, which restores active T-cell response directed at tumor cells, inducing an anti-tumor effect. This nonspecific activation of the immune system can also lead to a wide spectrum of side effects. Nivolumab has been used effectively to prolong survival in patients with metastatic melanoma and is recommended as a category 1 agent for systemic therapy in metastatic or unresectable melanoma per the National Comprehensive Cancer Network guidelines. We present a case of a 64-year-old woman who began nivolumab therapy for metastatic melanoma. After six doses of nivolumab therapy, the patient experienced generalized hypopigmentation on her face, chest, back, arms, and lower extremities. Although vitiligo has been reported in as many as 10.7% of patients undergoing nivolumab therapy in some clinical trials, we believe this is the first case to describe the progression of nivolumab-induced vitiligo in a metastatic melanoma patient. This case provides significant insight into the onset, symptoms, development, and treatment options for patients experiencing vitiligo as a result of nivolumab therapy.

    Full Text Available Background: This study aimed to assess the quality of life in vitiligo sufferers and its relationship with a number of variables such as age, gender, educational level, place of residence, marital status, disease duration, disease extension, visibility of lesions and skin phototype (SPT. Methods: In this study we evaluate the quality of life in patients with vitiligo attending Razi Hospital in July and August 2005. Permission from Professor Finlay was obtained to use the DLQI (Dermatology Life Quality Index questionnaire to evaluate the quality of life. One hundred patients with at least one vitiligo patch (age range= 14–57 answered the question-naire. Other survey questions about mentioned variables were also answered. Scoring was done according to Finlay`s guidelines. The higher the score, the greater the impairment of quality of life. Results: The mean DLQI score in our study was 8.16 (sd=5.423 with a minimum of 0 and a maximum of 28. There were statistically significant relationships between DLQI scores and marital status, skin phototype and disease extension independently, but not between DLQI scores and other variables. The mean DLQI score was significantly higher in married compared to single patients. In fact this difference was significant in women. Married women had a statistically higher score than single women while single and married men had no significant difference. Patients with Skin Phototype IV showed a higher DLQI score than other SPTs, which was statistically notable (p=0.000. The patients with more disease extension had higher score that was statistically significant (p=0.000. Conclusions: This study shows that vitiligo has a major impact on the quality of life and indicates specific groups that are most affected by the disease. Hence, dermatologists should pay attention to the psychologic effects of this cosmetic disease and try to decrease its extension and disfiguring effects by various treatment modalities.

    Objective: To explore the significance of changes of skin blister fluid NPY, IL-12, sICAM-1 and GM-CSF levels in patients with vitiligo in progressive stage. Methods: 80 patients with vitiligo in progressive stage were divided into two groups (vulgaris vitiligo groups : n=54, segmental vitiligo groups : n=26) Their blister fluid levels of NPY and GM-CSF were determined by radioimmunoassay(RIA), and IL-12 and sICAM-1 were determined by enzyme immunoassay. Results: The levels of skin blister fluid NPY were definitely higher in vitiliginous skin than those in non-vitiliginous patches in segmental vitiligo groups (P 0.05). The levels of skin blister fluid IL-12, sICAM-1 and GM-CSF were all obviously higher in vitiliginous skin than that in non-vitiliginous patches in vulgaris vitiligo groups (P 0.05). Conclusion: The changes of skin blister fluid NPY, IL-12, sICAM-1 and GM-CSF levels in vitiliginous skin may be closely related to development of difference type vitiligo patients with vitiligo, determination of 4 indexes might be helpful for studying the pathogenesis and clinical diagnosis of vitiligo.

    Full Text Available BACKGROUND: Vitiligo is an acquired pigmentary cutaneous disease, characterised by the progressive loss of melanocytes, resulting in hypopigmented skin areas which progressively become amelanotic. Classically, vitiligo treatments are unsatisfactory and challenging. Despite the continuous introduction of new therapies, phototherapy is still the mainstay for vitiligo repigmentation. AIM: The aim of this multicenter observational retrospective study was to evaluate the efficacy and safety of the nb - UVB micro - phototherapy (BIOSKIN EVOLUTION®, used alone or in associations with an oral Janus kinase inhibitor (Tofacitinib citrate, in the treatment of stable or active forms of localised vitiligo. MATERIAL AND METHODS: Fifty eight patients had been treated with n-UVB micro-photootherapy (Group A; 9 patients had been treated with phototherapy plus Tofacitinb citrate (Group B. RESULTS: Among Group A, 42 patients (72% obtained a re-pigmentation rate higher than 75%, with a medium value of 77%. 11 patients (19% achieved a marked improvement of the clinical findings with a repigmentation rate between 50-75%; 4 patients (8% showed a moderate response with a lesional repigmentation of 25-50%. Only one patient (1% had a poor response to the phototherapeutic treatment CONCLUSION: Nb - UVB micro-focused phototherapy is one of the most effective therapeutic options for vitiligo treatment. The association of micro-focused phototherapy to Tofacitinib citrate seems to provide better clinical results in term of repigmentation rate.

    Vitiligo is a chronic, depigmenting skin disorder, whose pathogenesis is still unknown. Narrow band ultraviolet-B (NB-UVB) is now one of the most widely used treatment of vitiligo. It was suggested that trace elements may play a role in pathogenesis of vitiligo. The aim of this study was to estimate the concentration of selenium (Se), zinc (Zn), copper (Cu) and Cu/Zn ratio as well as total antioxidant status (TAS) in the serum of patients with vitiligo. We assessed 50 patients with vitiligo and 58 healthy controls. Serum levels of Se, Zn and Cu were determined by the atomic absorption spectrometry method, and the Cu/Zn ratio was also calculated. TAS in serum was measured spectrophotometrically. Serum concentration of Se in patients with vitiligo before and after phototherapy was significantly lower as compared to the control group. Zn level in the serum of patients decreased significantly after phototherapy. We observed higher Cu/Zn ratio (p vitiligo patients after NB-UVB. The current study showed some disturbances in the serum levels of trace elements and total antioxidant status in vitiligo patients.

    Persistence of pigmentation after a melanocyte-keratinocyte transplantation procedure (MKTP) is an important consideration for efficacy. We sought to determine long-term repigmentation of MKTP in vitiligo and other leukodermas. A retrospective review of electronic medical records was conducted for all MKTPs performed at Henry Ford Hospital between January 2009 and April 2014. Repigmentation was assessed by a 5-point grading scale (poor to excellent) and Vitiligo Area Scoring Index (VASI). One hundred patients had MKTP performed at 236 anatomically-based lesions (ABLs); 63 patients with 157 ABLs had long-term data available (12-72 months; median, 24 months). Segmental vitiligo, nonsegmental vitiligo, and physical leukoderma demonstrated improvement in VASI scores: -75.6 ± 24.6%, -59.2 ± 36.6%, and -32.4 ± 33.5%, respectively. In vitiligo, at 24, 48, and 72 months after MKTP, 53%, 64%, and 53% of ABLs, respectively, maintained >75% repigmentation. Skin phototype, age, and anatomic location of ABLs had no significant effect on the outcome of treatment. Limitations of the study include the retrospective design with uncontrolled, postoperative adjuvant treatments and inconsistent compliance to scheduled follow-up evaluations. MKTP provides satisfactory long-term repigmentation in the majority of appropriately selected patients with leukoderma. MKTP can maintain repigmentation for at least 72 months. Copyright © 2017.

    2010-01-01

    Full Text Available Background: Vitiligo is an acquired pigmentary disorder of the skin that is caused by unknown factors and is characterized by white and depigmented patches that enlarge and become more numerous with time. Genetic factors, oxidative stress, autoimmunity, and neurochemical agents, such as catecholamines might also contribute to vitiligo. Cutaneous pigmentation is determined by the amounts of eumelanin and pheomelanin synthesized by the epidermal melanocytes and interference of melanocortin-1 receptor (MC1R, a G-protein coupled receptor, its normal agonist, alpha-melanocyte stimulating hormone (α-MSH, and key enzymes, such as tyrosinase, to protect against sun-induced DNA damage. The MC1R, a 7 pass trans-membrane G-protein coupled receptor, is a key control point in melanogenesis. Loss-of-function mutations at the MC1R are associated with a switch from eumelanin to pheomelanin production, resulting in a red or yellow coat color. Aim: In this research, we aim to examine the genetic variety of MC1R and α-MSH gene in 20 Iranian vitiligo patients and 20 healthy controls. Materials and Methods: Analysis of the MC1R coding gene was performed with direct sequencing. Results: We found the following 9 MC1R coding region variants: Arg163Gl (G488A, Arg227Leu (G680A, Val 97Phe (G289T, Asp184Asn (G550A, Arg227Lys (G680A, Arg142His (G425A, Val60Leu (G178T, Val247Met (C739A, and Val174Ile (G520A. We also found 2 frameshift changes: one of them was the Insertion of C (frameshift in Pro136, stop at Trp148 and the other, Insertion of G (frameshift in Pro256, stop at Trp 333. Of all the changes, the most common was Val60Leu at 5% in patients vs 20% in controls, Val247Met at 15% in patients vs 0% in controls and Val174Ile at 15% in controls and 0% in patients. The other variants showed a frequency <5% in both patients and controls. Also in this study, we have examined the frequency of single nucleotide polymorphisms within the α-MSH genes with direct sequencing in

    Full Text Available Vitiligo characteristically affecting the lateral lower lip (LLL is a common presentation in South Orissa. This type of lesion has rarely been described in literature. One hundred eighteen such cases were studied during the period from October 1999 to September, 2000. LLL vitiligo constituted 16.39% of all vitiligo patients. Both sexes were affected equally. The peak age of onset was in the 2nd decade, mean duration of illness 21.46 months. Fifty six patients had unilateral lesion (38 on the left and 18 on the right. Among the 62 patients having bilateral lesions, the onset was more frequent on the left (38 than either the right (8 or both sides together (16. All the patients were right handed. Association with local factors like infection, trauma, cheilitis, FDE etc were associated in 38.98% of cases, but systemic or autoimmune diseases were not associated. Positive family history was found in 22% of cases.

    The association of glutathione S-transferases M1/T1 (GSTM1/T1) null polymorphisms with vitiligo was proposed in several studies including two Egyptian studies with contradictory results. The aim here was to assess the association between GSTM1/T1 null polymorphisms and the susceptibility to vitiligo in a larger sample of Egyptian patients with generalized vitiligo. This study included 122 vitiligo patients and 200 healthy controls that were age, and gender matched. Assessment of GSTM1/T1 gene polymorphisms was done using a multiplex polymerase chain reaction (PCR). Increased odds of generalized vitiligo was observed with the null genotypes of GSTM1 and GSTT1 polymorphisms (Pvitiligo (OR=2.97, 95%CI=1.1-7.7) (P=0.02) compared with patients. Small sample size of patients. This study showed a significant trend towards an association with the combination of the GSTM1/GSTT1 double null polymorphism and generalized vitiligo. Individuals with GSTM1 null/GSTT1+ heterozygosis have a 2.97 odds protection from having generalized vitiligo compared with patients. It was is the first time, to our knowledge, that such an association has been reported.

    Segmental vitiligo is characterized by its early onset, rapid stabilization, and unilateral distribution. Recent evidence suggests that segmental and nonsegmental vitiligo could represent variants of the same disease spectrum. Observational studies with respect to its distribution pattern point to a possible role of cutaneous mosaicism, whereas the original stated dermatomal distribution seems to be a misnomer. Although the exact pathogenic mechanism behind the melanocyte destruction is still unknown, increasing evidence has been published on the autoimmune/inflammatory theory of segmental vitiligo.

  10. Vitiligo and Autoimmune Thyroid Disorders

    Directory of Open Access Journals (Sweden)

    Enke Baldini

    2017-10-01

    Full Text Available Vitiligo represents the most common cause of acquired skin, hair, and oral depigmentation, affecting 0.5–1% of the population worldwide. It is clinically characterized by the appearance of disfiguring circumscribed skin macules following melanocyte destruction by autoreactive cytotoxic T lymphocytes. Patients affected by vitiligo usually show a poorer quality of life and are more likely to suffer from depressive symptoms, particularly evident in dark-skinned individuals. Although vitiligo is a non-fatal disease, exposure of affected skin to UV light increases the chance of skin irritation and predisposes to skin cancer. In addition, vitiligo has been associated with other rare systemic disorders due to the presence of melanocytes in other body districts, such as in eyes, auditory, nervous, and cardiac tissues, where melanocytes are thought to have roles different from that played in the skin. Several pathogenetic models have been proposed to explain vitiligo onset and progression, but clinical and experimental findings point mainly to the autoimmune hypothesis as the most qualified one. In this context, it is of relevance the strong association of vitiligo with other autoimmune diseases, in particular with autoimmune thyroid disorders, such as Hashimoto thyroiditis and Graves’ disease. In this review, after a brief overview of vitiligo and its pathogenesis, we will describe the clinical association between vitiligo and autoimmune thyroid disorders and discuss the possible underlying molecular mechanism(s.

    Blue vitiligo is a distinct variant of vitiligo characterized by a blue-grey appearance of the skin, which corresponds histologically with absence of epidermal melanocytes and presence of numerous dermal melanophages. A 23-year-old woman of Indian origin with Fitzpatrick skin type V presented with a 1-month history of normoaesthetic depigmented macules over the right forearm, dorsa of the hands and right areola. The macule over the right forearm had a bluish tinge. A clinical diagnosis of vitiligo vulgaris with blue vitiligo was made. Dermatoscopy of the interface between the blue macule and the hypopigmented macule revealed a linear depigmented macule in the centre with multiple blue dots and absence of epidermal melanin on the side of the blue macule, and reticular pigmentation with a few depigmented macules and scattered blue dots over the side of the hypopigmented macule. Blue vitiligo was described previously in a patient seropositive for human immunodeficiency virus, and believed to represent postinflammatory hyperpigmentation in areas bordering the vitiliginous patches as a result of psoralen ultraviolet A treatment. This case is unusual because of its rarity and the description of the associated dermatoscopical findings.

    Vitiligo is a chronic stigmatizing disease, already known for millennia, which mainly affects melanocytes from epidermis basal layer, leading to the development of hypochromic and achromic patches. Its estimated prevalence is 0.5% worldwide. The involvement of genetic factors controlling susceptibility to vitiligo has been studied over the last decades, and results of previous studies present vitiligo as a complex, multifactorial and polygenic disease. In this context, a few genes, including DDR1, XBP1 and NLRP1 have been consistently and functionally associated with the disease. Notwithstanding, environmental factors that precipitate or maintain the disease are yet to be described. The pathogenesis of vitiligo has not been totally clarified until now and many theories have been proposed. Of these, the autoimmune hypothesis is now the most cited and studied among experts. Dysfunction in metabolic pathways, which could lead to production of toxic metabolites causing damage to melanocytes, has also been investigated. Melanocytes adhesion deficit in patients with vitiligo is mainly speculated by the appearance of Köebner phenomenon, recently, new genes and proteins involved in this deficit have been found.

    Full Text Available Background: Vitiligo, a common disorder of depigmentation, is often difficult to treat. Corticosteroids are known to be effective, but with modest results. Although simvastatin has been reported to be effective for immunorelated dermatologic disorders including vitiligo, controlled trials are lacking. This study was conducted to compare the efficacy of topical betamethasone valerate 0.1% cream (as a standard method of treatment for vitiligo versus a combination of betamethasone valerate plus oral simvastatin in the treatment of vitiligo. Materials and Methods: Eighty-eight subjects with symmetric vitiligo who had body surface involvement up to 20% were divided randomly into two groups. Group A were treated with betamethasone valerate 01% cream twice daily and Group B with betamethasone valerate 01% cream twice daily and oral simvastatin 80 mg daily for 12 weeks. Finally, 46 patients completed treatment after 12 weeks in both groups. The results were evaluated by a blind dermatologist using Vitiligo Area Scoring Index (VASI score at baseline, 4th, 8th, and 12th week of treatment. In a similar way, subjective assessment performed by patients based on photo evaluation at the end of the study. Results: Despite a continuous reduction in VASI score in both groups, according to both physician (P = 0.13 and patient (P = 0.374 assessment oral simvastatin was not statistically more effective than conventional treatment of vitiligo. Conclusion: This study indicates that oral simvastatin is not associated with significant impacts in the treatment of vitiligo as compared to other inflammatory dermatologic conditions such as psoriasis. Indeed, other studies should be initiated regarding exact molecular and cellular effects of statins in the treatment of vitiligo.

    Full Text Available Vitiligo is a refractory skin disease. To investigate the risk factors and treatment responses of patients with vitiligo in Japan, we recorded and analyzed the details of 713 vitiligo patients (comorbidity, treatment responses, family history, age, and sex who visited the dermatology clinic of the Nagoya City University Hospital, Nagoya, Japan between January 2004 and August 2010 (mean age, 35.2 years; 302 men, 411 women using logistic regression analysis. The results are expressed as odds ratios (OR with 95% confidence interval (CI. Patients were diagnosed with vitiligo [n = 644; 338 generalized type (47.4%, 170 segmental type (23.8%, and 136 localized type (19.1%], nevus depigmentosus (n = 53, 7.4%, halo nevus (n = 14, 2.0%, and hypomelanosis of Ito (n = 2, 0.3%. For generalized and localized types, none of the analyzed factors were statistically significant. For the segmental type, antinuclear antibody (OR = 1.005; 95% CI, 1.00–1.01; p 55 years (OR = 0.0171; 95% CI, 0.00333–0.0879; p < 0.001. The treatment response rates for narrow-band UV-B, topical vitamin D3, and punch graft (1 mm minigraft were, respectively, as follows: (1 generalized type: 46.3%, 21.1%, and 38.9%; (2 segmental type: 20.3%, 29.0%, and 77.3%; and (3 localized type: 29.2%, 54.8%, and 73.3%. We report the comorbidities and efficacy rates of these treatments. The response data for these treatments, in particular, would be of assistance to the previous explanations, because there were only a few reports on the response data for these treatments. The appropriate treatment should be selected depending on the type of vitiligo.

    It is believed that vitiligo has an impact on the overall patient quality of life (QoL). To estimate QoL in a fairly large sample of Italian vitiligo patients by using the Dermatology Life Quality Index (DLQI) questionnaire. 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. 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. 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.

    On average, vitiligo affects one percent of the world population. More than 75% of the patients have negative self-image on account of the disease. The emotional impact of the dermatosis is frequently neglected by the caretaker, which has negative influence on therapy and prognosis. OBJECTIVE; To check the effect of vitiligo on patients emotions and discuss the mind-body interaction and its impact on the disease. METHODS; In their first medical visit, one hundred patients with various forms of vitiligo answered a question about which emotions were elicited by the presence of the spots. RESULTS; Eighty-eight percent of the patients with spots in exposed areas complained of unpleasant emotions versus twenty-seven percent of those with spots in unexposed areas. The most frequently referred emotions were fear, specifically of expansion of the spots (71%), shame (57%), insecurity (55%), sadness (55%) and inhibition (53%). CONCLUSION; Chronic illnesses generate in human beings a negative experience propitiated by the expectation of suffering. Besides appropriate scientific guidance, vitiligo patients need emotional comfort. Treatment outcomes and patients compliance to it, and even their resilience to face occasional therapeutic failures, rely on good physician-patient relationship. At a time when doctors make use of reputable therapeutic resources, it is indispensable that dermatologists become able to evaluate the patient in an integrative fashion.

    Follicular vitiligo, a recently proposed new subtype of vitiligo, has primary involvement of the hair follicle melanocytic reservoir. We sought to characterize follicular vitiligo through a case series of 8 patients. Patients with features of follicular vitiligo who were seen at the vitiligo clinic in the National Center for Rare Skin Disorders in Bordeaux, France, were recruited. A retrospective review of case records and clinical photographs was carried out. There were 8 male patients with a mean age of 48 years. All patients reported significant whitening of their body and, in some, scalp hairs before cutaneous depigmentation. Examination revealed classic generalized depigmented lesions of vitiligo and an impressive presence of leukotrichia, not only in the vitiliginous areas, but also in areas with clinically normal-appearing skin. Punch biopsy specimen of the leukotrichia and vitiligo lesions demonstrated loss of melanocytes and precursors in the basal epidermis and hair follicle. This was a cross-sectional study based on a single-center experience. Follicular vitiligo is a distinct entity within the spectrum of vitiligo. This entity may serve as the missing link between alopecia areata and vitiligo, with probable physiopathological similarities between these conditions.

    Andries Blokzijl

    Full Text Available The diagnosis of malignant melanoma currently relies on clinical inspection of the skin surface and on the histopathological status of the excised tumor. The serum marker S100B is used for prognostic estimates at later stages of the disease, but analyses are marred by false positives and inadequate sensitivity in predicting relapsing disorder.To investigate SOX10 as a potential biomarker for melanoma and vitiligo.In this study we have applied proximity ligation assay (PLA to detect the transcription factor SOX10 as a possible serum marker for melanoma. We studied a cohort of 110 melanoma patients. We further investigated a second cohort of 85 patients with vitiligo, which is a disease that also affects melanocytes.The specificity of the SOX10 assay in serum was high, with only 1% of healthy blood donors being positive. In contrast, elevated serum SOX10 was found with high frequency among vitiligo and melanoma patients. In patients with metastases, lack of SOX10 detection was associated with treatment benefit. In two responding patients, a change from SOX10 positivity to undetectable levels was seen before the response was evident clinically.We show for the first time that SOX10 represents a promising new serum melanoma marker for detection of early stage disease, complementing the established S100B marker. Our findings imply that SOX10 can be used to monitor responses to treatment and to assess if the treatment is of benefit at stages earlier than what is possible radiologically.

    Vitiligo is an autoimmune disease with a strong genetic component, characterized by areas of depigmented skin resulting from loss of epidermal melanocytes. Genetic factors are known to play key roles in vitiligo through discoveries in association studies and family studies. Previously, vitiligo susceptibility genes were mainly revealed through linkage analysis and candidate gene studies. Recently, our understanding of the genetic basis of vitiligo has been rapidly advancing through genome-wide association study (GWAS). More than 40 robust susceptible loci have been identified and confirmed to be associated with vitiligo by using GWAS. Most of these associated genes participate in important pathways involved in the pathogenesis of vitiligo. Many susceptible loci with unknown functions in the pathogenesis of vitiligo have also been identified, indicating that additional molecular mechanisms may contribute to the risk of developing vitiligo. In this review, we summarize the key loci that are of genome-wide significance, which have been shown to influence vitiligo risk. These genetic loci may help build the foundation for genetic diagnosis and personalize treatment for patients with vitiligo in the future. However, substantial additional studies, including gene-targeted and functional studies, are required to confirm the causality of the genetic variants and their biological relevance in the development of vitiligo.

    Vitiligo is an acquired chronic depigmenting disorder of the skin, with an estimated prevalence of 0.5% of the general population, characterized by the development of white macules resulting from a loss of epidermal melanocytes. The nomenclature has been revised after an extensive international work within the vitiligo global issues consensus conference, and vitiligo (formerly non-segmental vitiligo) is now a consensus umbrella term for all forms of generalized vitiligo. Two other subsets of vitiligo are segmental vitiligo and unclassified/undetermined vitiligo, which corresponds to focal disease and rare variants. A series of hypopigmented disorders may masquerade as vitiligo, and some of them need to be ruled out by specific procedures including a skin biopsy. Multiple mechanisms are involved in melanocyte disappearance, namely genetic predisposition, environmental triggers, metabolic abnormalities, impaired renewal, and altered inflammatory and immune responses. The auto-immune/inflammatory theory is the leading hypothesis because (1) vitiligo is often associated with autoimmune diseases; (2) most vitiligo susceptibility loci identified through genome-wide association studies encode immunomodulatory proteins; and (3) prominent immune cell infiltrates are found in the perilesional margin of actively depigmenting skin. However, other studies support melanocyte intrinsic abnormalities with poor adaptation of melanocytes to stressors leading to melanocyte instability in the basal layer, and release of danger signals important for the activation of the immune system. Recent progress in the understanding of immune pathomechanisms opens interesting perspectives for innovative treatment strategies. The proof of concept in humans of targeting of the IFNγ /Th1 pathway is much awaited. The interplay between oxidative stress and altered immune responses suggests that additional strategies aiming at limiting type I interferon activation pathway as background stabilizing

    Cosmetic camouflage is indispensable for patients with vitiligo and can result in an improvement of their quality of life. Recent cosmetic advances enabled camouflage to obtain a suitable color match and keep it waterproof. However, camouflage needs some techniques. Therefore, patient education through a camouflage lesson is required to enjoy camouflage. Here the authors introduced a few tips for suitable camouflage, which were devised through camouflage lessons.

    Full Text Available The significant inter-patient variability in progression, and response to therapy makes it a great challenge for the physician to predict the outcome of vitiligo at the very outset. Subjective factors like stress, pregnancy, sunburn and illness have been identified as aggravating factors for vitiligo. However, a few studies have evaluated the statistical significance of objective clinical parameters in predicting the outcome of vitiligo. Our retrospective analysis of 199 consecutive patients with vitiligo who presented to our OPD was aimed at evaluation of these objective clinical parameters utilizing a standard proforma. Patients already on treatment, and those with duration of disease less than 6 months were excluded from the study. Progression was defined as an increase in size or number of lesions in the 3 months prior to presentation. In all 76. 9% patients had progression of vitiligo. The clinical parameters significantly associated with progression were a positive family history (p=0. 027, mucosal involvement (p=0. 032, Koebner′s phenomenon (p=0. 036 and nonsegmental vitiligo (p=0. 033. Thrichrome sign, leucotrichia, longer duration and higher age at onset did not correlate significantly with progression. The one significant observation that we found to have the poor prognostic implication in vitiligo is the presence of mucosal vitiligo. The clinical prediction of disease progression at the outset enables the physician to set realistic treatment goals and optimize the therapeutic regimen for the individual patient.

    Objective: To explore the changes of serum IL-2, IL-4 and IFN-γ levels after treatment in patients with vitiligo. Methods: Serum IL-2 (with RIA) IL-4, IFN-γ (with ELISA) levels were examined in 37 patients with vitiligo both before and after treatment as well as in 35 controls. Results: Before treatment, serum IL-2 levels in the patients were significantly lower than those in controls (P < 0.01), while the serum IL-4, IFN-γ levels were significantly higher (P < 0.01). After treatment for 6 months, the values were greatly corrected, but remained significantly different from those in controls (P < 0.05). Conclusion: Vitiligo is a kind of auto-immune diseases with abnormal immuno-regulation. (authors)

    Full Text Available BACKGROUND: Vitiligo is a prevalent skin pigmentation disorder worldwide. The treatments available still offer limited results to some patients. For patients with clinically stable vitiligo, melanocyte transplantation is an appropriate treatment option, and the technique of autologous punch grafting shows good repigmentation. OBJECTIVE: To evaluate the effect of topical mometasone on the halos of repigmentation after autologous punch grafting in patients with clinically stable vitiligo. METHODS: Between 2009 and 2010, 11 patients with clinically stable vitiligo (7 generalized, 2 focal and 2 segmental underwent autologous punch grafting in the achromic patches. According to the clinical type of vitiligo, patients were instructed to use the corticosteroid ointment during 6 months, only on a few grafted lesions. In the first month, the mometasone ointment was used twice a day and after that just once. They were reassessed 1, 3 and 6 months after the procedure. Grafted halos were photographed and recorded using the software fotofinder. After 6 months, all the treated and untreated areas of the repigmentation halos were measured and analyzed comparatively. RESULTS: The median area of the repigmentation halos after 6 months of treatment with mometasone was larger (25,96 mm² than the one of the untreated halos (13,86 mm² , showing a statistically significant difference (p = 0,026. CONCLUSION: In this study, the use of mometasone ointment increased the area of the repigmentation halos after punch grafting. However, this should be further investigated in larger samples in order to validate this positive action in the treatment of stable vitiligo.FUNDAMENTOS: Vitiligo é um transtorno de pigmentação freqüente na população mundial.

    2016-01-01

    Synopsis Chemical-induced depigmentation of the skin has been recognized for over 75 years, first as an occupational hazard but then extending to those using household commercial products as common as hair dyes. Since their discovery, these chemicals have been used therapeutically in patients with severe vitiligo to depigment their remaining skin and improve their appearance. The importance of recognizing this phenomenon was highlighted during an outbreak of vitiligo in Japan during the summer of 2013, when over 16,000 users of a new skin lightening cosmetic cream developed skin depigmentation at the site of contact with the cream and many in remote areas as well. Depigmenting chemicals appear to be analogs of the amino acid tyrosine that disrupt melanogenesis and result in autoimmunity and melanocyte destruction. Because chemical-induced depigmentation is clinically and histologically indistinguishable from non-chemically induced vitiligo, and because these chemicals appear to induce melanocyte autoimmunity, this phenomenon should be known as “chemical-induced vitiligo”, rather than less accurate terms that have been previously used.

    Full Text Available Background : Recent clinical and animal experimental studies postulate that the pathogenetic mechanisms of vitiligo could be of systemic origin as vitiligo is associated with ocular and auditory abnormalities as well as other autoimmune disorders.Hence, we studied genetic factors, systemic associations, ocular and auditory abnormalities of vitiligo. Methods: The study group included 150 new cases of various types of vitiligo. One hundred age- and sex-matched nonvitiligo cases were included as controls in the study. A complete family history was taken for all patients. Examination was carried out taking note of the type of vitiligo and approximate percentage of body surface involved. All relevant laboratory investigations, a thorough audiological examination including pure tone audiometry and a complete ophthalmologic examination were carried out in all patients and controls. Statistical analysis was done using the Chi square test. Results: Fifty-four vitiligo patients (36% had a family history of vitiligo. Anemia was present in 30 (20% vitiligo patients but only in five (5% controls, a difference that was statistically significant (c2 = 15.8, P < 0.001. Diabetes mellitus was present in 24 (16% vitiligo patients and only 2 (2% of controls (Chi square, c2 = 12.4, P < 0.001. Hypothyroidism and alopecia areata were present in 18 (12% and 11 (7.4% vitiligo patients respectively and none of the controls. Hypoacusis was seen in 30 (20% vitiligo patients and two (2% controls (c2 = 8.19, P < 0.005. Twenty-four vitiligo patients (16% and five controls (5% had specific ocular abnormalities like uveitis, iris and retinal pigmentary abnormalities (c2 = 7.39, P < 0.001. Conclusion: This study demonstrates statistically significant clinical evidence confirming that vitiligo is a part of systemic autoimmune process.

    Full Text Available Background: Vitiligo is the most common pigmentary skin disorder. It is a multifactorial polygenic disease with epidermal melanocyte destruction. The cytokines profile found in vitiliginous patients was not fully elucidated. Aims: We sought to assess the autoimmune nature of vitiligo by comparing plasma levels of interleukin (IL-17, IL-23, and transforming growth factor beta (TGF-b in adult Sudanese vitiligo patients with matched control individuals. Subjects and Methods: Case-control study was conducted in Khartoum Dermatologic Teaching Hospital, in the period between July and December 2013. The cases were 42 adult Sudanese vitiligo patients matched with 43 control individuals. The cytokines were measured in the plasma by the quantitative "sandwich" ELISA. Results: Patients showed a significant lower median (25-75 th inter-quartile of TGF-β than control (0.042 [0.041-0.044] vs. 0.047 [0.042-0.049]; P ͳ 0.001. Both IL-17 and IL-23 showed no significant difference between cases and controls. IL-17 showed a significant inverse relationship when correlated with TGF-β (r = −0.24; P = 0.026 while showing direct relationship when correlated with age (r = 0.28; P = 0.009. Conclusion: The positive findings detected in this study coincide with the important immunoregulatory role of the TGF-β, and support the autoimmune nature of the disease.

    In patients with vitiligo, an increased reactive oxygen species (ROS) level has been proved to be a key player during disease initiation and progression in melanocytes. Nevertheless, little is known about the effects of ROS on other cells involved in the aberrant microenvironment, such as keratinocytes and the following immune events. CXCL16 is constitutively expressed in keratinocytes and was recently found to mediate homing of CD8 + T cells in human skin. We sought to explicate the effect of oxidative stress on human keratinocytes and its capacity to drive CD8 + T-cell trafficking through CXCL16 regulation. We first detected putative T-cell skin-homing chemokines and ROS in serum and lesions of patients with vitiligo. The production of candidate chemokines was detected by using quantitative real-time PCR and ELISA in keratinocytes exposed to H 2 O 2 . Furthermore, the involved mediators were analyzed by using quantitative real-time PCR, Western blotting, ELISA, and immunofluorescence. Next, we tested the chemotactic migration of CD8 + T cells from patients with vitiligo mediated by the CXCL16-CXCR6 pair using the transwell assay. CXCL16 expression increased and showed a positive correlation with oxidative stress levels in serum and lesions of patients with vitiligo. The H 2 O 2 -induced CXCL16 expression was due to the activation of 2 unfolded protein response pathways: kinase RNA (PKR)-like ER kinase-eukaryotic initiation factor 2α and inositol-requiring enzyme 1α-X-box binding protein 1. CXCL16 produced by stressed keratinocytes induced migration of CXCR6 + CD8 + T cells derived from patients with vitiligo. CXCR6 + CD8 + T-cell skin infiltration is accompanied by melanocyte loss in lesions of patients with vitiligo. Our study demonstrated that CXCL16-CXCR6 mediates CD8 + T-cell skin trafficking under oxidative stress in patients with vitiligo. The CXCL16 expression in human keratinocytes induced by ROS is, at least in part, caused by unfolded protein response

    Despite of numerous investigations, carried out practically in all countries of the world for the study of vitiligo and the search for its new effective therapies, pathogenic mechanisms of vitiligo are still poorly understood, and the proposed treatments are not perfect. One of the most accepted theories of the pathogenesis of vitiligo is an oxidative stress theory, according to which a series of biochemical anomalies cause oxidative stress, leading to accumulation of melanocytotoxic substances and inhibition of natural processes of detoxification with subsequent destruction of melanocytes in vitiligo focus. On the other hand, the use of antioxidants in combination with ultraviolet therapy of dermatological diseases, has been theoretically proved by biophysical studies, according to which- the antioxidants inhibit the oxidation of products, formed in the skin after ultraviolet irradiation and greatly reduce erythema sensitivity (1.5-2 times). Due to this effect, the power of radiation exposure can be approximately increased many times. Based on the foregoing, the use of antioxidants during phototherapy of vitiligo pathogenetically is justified. The aim of the study was to evaluate the therapeutic efficacy of Se ACE in treatment of patients with various forms of vitiligo. 35 patients (23 women and 12 men) aged 18 to 40 years with duration of the pathological process from 2 months to 15 years were under observation. 17 of these were diagnosed with a form of non segmental vitiligo (NSV), 18- segmental vitiligo. In 11 patients onset of the disease was not connected with any other problem, 24 noted the appearance of white spots after stress. Vitiligo patients were divided into 2 groups: the study group and the group of comparison. The study group included 17 patients (9 women and 8 men) aged 18 to 40 years with duration of the disease from 2 months to 5 years. The comparison group consisted of 18 patients (10 women and 8 men). Distribution of patients in both groups was

    Full Text Available FUNDAMENTOS: O vitiligo acomete, em média, 1% da população mundial. Mais de 75% dos pacientes têm autoimagem depreciativa em relação à doença. Seu impacto emocional é muitas vezes negligenciado pelo cuidador, influenciando negativamente o prognóstico. OBJETIVO: Verificar o efeito do vitiligo sobre as emoções e discutir as últimas descobertas sobre a interação mente? corpo e seu desdobramento sobre a doença. MÉTODOS: Cem pacientes com diversas formas de vitiligo responderam, na primeira consulta, a uma pergunta sobre as emoções que a presença das manchas lhes provocava. RESULTADOS: Entre os que apresentavam manchas em áreas expostas, 80% queixaram-se de emoções desagradáveis, em contraposição a 37% dos que tinham manchas em áreas não expostas. As emoções mais referidas foram medo (71%, vergonha (57%, insegurança (55%, tristeza (55% e inibição (53%. CONCLUSÃO: Qualquer doença crônica produz nos seres humanos uma vivência negativa propiciada pela expectativa de sofrimento. O vitiligo é um desafio à autoestima. Além de uma orientação científica adequada, o paciente de vitiligo carece de conforto emocional. A resposta e a adesão ao tratamento e até mesmo a resiliência diante de eventuais falhas terapêuticas dependem da boa relação médico-paciente. Numa época em que dispomos de respeitável terapêutica, torna-se indispensável que o dermatologista se mostre apto a avaliar seu paciente holisticamente.BACKGROUND: On average, vitiligo affects one percent of the world population.

  1. Genetics of Vitiligo

    Spritz, Richard; Andersen, Genevieve

    2016-01-01

    Synopsis Vitiligo is “complex disorder” (also termed polygenic and multifactorial), reflecting simultaneous contributions of multiple genetic risk factors and environmental triggers. Large-scale genome-wide association studies, principally in European-derived whites and in Chinese, have discovered approximately 50 different genetic loci that contribute to vitiligo risk, some of which also contribute to other autoimmune diseases that are epidemiologically associated with vitiligo. At many of these vitiligo susceptibility loci the corresponding relevant genes have now been identified, and for some of these genes the specific DNA sequence variants that contribute to vitiligo risk are also now known. A large fraction of these genes encode proteins involved in immune regulation, a number of others play roles in cellular apoptosis, and still others are involved in regulating functions of melanocytes. For this last group, there appears to be an opposite relationship between susceptibility to vitiligo and susceptibility to melanoma, suggesting that vitiligo may engage a normal mechanism of immune surveillance for melanoma. While many of the specific biologic mechanisms through which these genetic factors operate to cause vitiligo remain to be elucidated, it is now clear that vitiligo is an autoimmune disease involving a complex relationship between programming and function of the immune system, aspects of the melanocyte autoimmune target, and dysregulation of the immune response.

    Vitiligo is not a life–threatening nor a contagious disease. But the disfigurement of vitiligo can be devastating to its sufferers, especially dark-skinned individuals. Available treatment options are disappointing and sufferers often use various forms of camouflage. Remedial cosmetic cover creams help conceal the blemish of vitiligo at least temporarily. A high concentration of pigment is incorporated into water–free or anhydrous foundations to give a color that matches the patient’s skin, thereby concealing vitiligo patches. The article highlights the content and technique of application of these creams. PMID:21063508

    Vitiligo is characterized by progressive loss of skin pigmentation. The search for etiologic factors has led to the biochemical, the neurologic and the autoimmune theory. The convergence theory was then proposed several years ago to incorporate existing theories of vitiligo development into a single overview of vitiligo etiology. The viewpoint that vitiligo is not caused only by predisposing mutations, or only by melanocytes responding to chemical/radiation exposure, or only by hyperreactive T cells, but rather results from a combination of etiologic factors that impact melanocyte viability, has certainly stood the test of time. New findings have since informed the description of progressive depigmentation. Understanding the relative importance of such etiologic factors combined with a careful selection of the most targetable pathways will continue to drive the next phase in vitiligo research: the development of effective therapeutics. In that arena it is likewise important to acknowledge that pathways affected in some patients may not be altered in others. Taken together, the convergence theory continues to provide a comprehensive viewpoint of vitiligo etiology. The theory serves to intertwine etiologic pathways and will help to define pathways amenable to disease intervention in individual patients. This article is protected by copyright.

    Vitiligo is an autoimmune skin disorder in which the loss of melanocytes is mainly attributed to defective autoimmune mechanisms and, lately, there has been more emphasis on autoinflammatory mediators. Among these is the macrophage migration inhibitory factor, which is involved in many autoimmune skin diseases. However, little is known about the contribution of this factor to vitiligo vulgaris. To determine the hypothesized role of migration inhibitory factor in vitiligo via estimation of serum migration inhibitory factor levels and migration inhibitory factor mRNA concentrations in patients with vitiligo compared with healthy controls. We also aimed to assess whether there is a relationship between the values of serum migration inhibitory factor and/or migration inhibitory factor mRNA with disease duration, clinical type and severity in vitiligo patients. Evaluation of migration inhibitory factor serum level and migration inhibitory factor mRNA expression by ELISA and real-time PCR, respectively, were performed for 50 patients with different degrees of vitiligo severity and compared to 15 age- and gender-matched healthy volunteers as controls. There was a highly significant increase in serum migration inhibitory factor and migration inhibitory factor mRNA levels in vitiligo cases when compared to controls (pvitiligo patients, and each of them with duration and severity of vitiligo. In addition, patients with generalized vitiligo have significantly elevated serum migration inhibitory factor and mRNA levels than control subjects. Small number of investigated subjects. Migration inhibitory factor may have an active role in the development of vitiligo, and it may also be a useful index of disease severity. Consequently, migration inhibitory factor may be a new treatment target for vitiligo patients.

  5. Epidermal hydrogen peroxide is not increased in lesional and non-lesional skin of vitiligo.

    2017-01-01

    It is widely believed that the loss of the epidermal melanocytes in vitiligo is basically due to excessive oxidative stress. Previous research work described abnormal elevation of the absolute concentration of the epidermal hydrogen peroxide (H 2 O 2 ) in lesional and non-lesional skin of vitiligo. Based on this finding, our primary research objective was to use this feature as a screening marker in individuals at a great risk of developing vitiligo. Ninety-six patients of non-segmental vitiligo (NSV) of varying durations, skin phototypes, and treatment modalities (psoralen UVA-, narrow band UVB-treated) were recruited for this study. Raman spectroscopic measurements, using an external probehead, of the lesional and non-lesional skin were obtained, and the resulting spectra were analyzed using the Opus software package of the MultiRam spectrometer and the intensity of the peak at 875 cm -1 that represents the absolute concentration of H 2 O 2 was calculated. Contrary to previous reports, in patients of skin phototype IV, the absolute concentrations of H 2 O 2 in non-lesional and lesional NSV of all groups were non-significantly decreased compared to normal control. In patients of NSV of skin phototype V, the decrease in the absolute concentrations of H 2 O 2 was not significant in the untreated group, and a slight non-significant increase in the NBUVB-treated group was noted. However, in the PUVA-treated group, the non-lesional skin demonstrated significant increase in the absolute concentration of H 2 O 2 , whereas the lesional skin showed only a slight non-significant increase compared to normal control. In NSV patients of skin phototype VI who were previously treated with PUVA, the non-lesional skin showed a slight non-significant increase in the absolute concentration of H 2 O 2 ; however, the lesional skin showed a marked significant decrease compared to normal control and the non-lesional skin. Thereof, one can conclude that the epidermal H 2 O 2 is not

    Vitiligo is a chronic autoimmune skin disease caused by the destruction of melanocytes. Although quality of life (QOL) in vitiligo has been studied in different countries, it has not yet been investigated in Mexico. The aim of this study was to assess the QOL of Mexican patients with vitiligo. We conducted a cross-sectional study at the research unit of Centro Dermatológico Dr. Ladislao de la Pascua in Mexico City. We included adults with vitiligo and excluded those with other pigmentation disorders or a neurological or psychiatric disorder. Patients on psychoactive medications were also excluded. All the patients were administered the Dermatology Life Quality Index (DLQI), a vitiligo-specific quality of life instrument (the VitiQoL), and the Beck Depression and Anxiety Inventories. We studied 150 patients with vitiligo (103 women [68.7%] and 47 men [31.3%]). The median (interquartile range) age was 38 (20) years. The mean (SD) scores on the DLQI and VitiQoL were 5.2 (5.4) and 32.1 (22.7) out of total possible scores of 30 and 90, respectively. The correlation between questionnaire scores was 0.675 (P<.001). Patients with genital involvement scored significantly worse on the VitiQoL than those without lesions in this area (43.95 [28.4]) vs. 28.98 [20.08], P<.001). The prevalence of depression and anxiety was 34% and 60%, respectively. Vitiligo has a minimal impact on the QOL of our patients. QOL was worse in patients with genital lesions.

    2008-03-01

    Full Text Available Vitiligo surgery is an effective method of treatment for selected, resistant vitiligo patches in patients with vitiligo. Physician′s qualifications: The physician performing vitiligo surgery should have completed postgraduate training in dermatology which included training in vitiligo surgery. If the center for postgraduation does not provide education and training in cutaneous surgery, the training may be obtained at the surgical table (hands-on under the supervision of an appropriately trained and experienced dermatosurgeon at a center that routinely performs the procedure. Training may also be obtained in dedicated workshops. In addition to the surgical techniques, training should include local anesthesia and emergency resuscitation and care. Facility: Vitiligo surgery can be performed safely in an outpatient day care dermatosurgical facility. The day care theater should be equipped with facilities for monitoring and handling emergencies. A plan for handling emergencies should be in place, with which all nursing staff should be familiar. Vitiligo grafting for extensive areas may need general anesthesia and full operation theater facility in a hospital setting and the presence of an anesthetist is recommended in such cases. Indications for vitiligo surgery : Surgery is indicated for stable vitiligo that does not respond to medical treatment. While there is no consensus on definitive parameters for stability, the Task Force suggests the absence of progression of disease for the past one year as a definition of stability. Test grafting may be performed in doubtful cases to detect stability. Preoperative counseling and Informed consent: A detailed consent form elaborating the procedure and possible complications should be signed by the patient. The patient should be informed of the nature of the disease and that the determination of stability is only a vague guide. The consent form should specifically state the limitations of the procedure

    Vitiligo is a common disease that causes a great degree of psychological distress. In its classical forms it is easily recognised and diagnosed. This review provides an evidence based outline of the management of vitiligo, particularly with the non-specialist in mind. Treatments for vitiligo are generally unsatisfactory. The initial approach to a patient who is thought to have vitiligo is to make a definite diagnosis, offer psychological support, and suggest supportive treatments such as the use of camouflage cosmetics and sunscreens, or in some cases after discussion the option of no treatment. Active therapies open to the non-specialist, after an explanation of potential side effects, include the topical use of potent or highly potent steroids or calcineurin inhibitors for a defined period of time (usually 2 months), following which an assessment is made to establish whether or not there has been a response. Patients whose condition is difficult to diagnose, unresponsive to straightforward treatments, or is causing psychological distress, are usually referred to a dermatologist. Specialist dermatology units have at their disposal phototherapy, either narrow band ultraviolet B or in some cases photochemotherapy, which is the most effective treatment presently available and can be considered for symmetrical types of vitiligo. Depigmenting treatments and possibly surgical approaches may be appropriate for vitiligo in selected cases. There is no evidence that presently available systemic treatments are helpful and safe in vitiligo. There is a need for further research into the causes of vitiligo, and into discovering better treatments.

    The development of vitiligo during treatment with biological agents is an unusual event and only a few isolated cases have been reported. To describe the clinical characteristics and evolution of patients developing new-onset vitiligo following initiation of a biological agent for chronic inflammatory disease; and also to report the clinical course of pre-existing vitiligo under biological therapy. This nationwide multicentre, retrospective study, carried out between July 2013 and January 2015, describes the characteristics of a large series of 18 patients (psoriasis N = 8, inflammatory rheumatic diseases N = 8, ulcerative colitis N = 1, uveitis N = 1) who developed new-onset vitiligo while receiving a biological agent. TNFα inhibitors were the most common biological agent involved (13/18) while anti-IL-12/23 and anti-IL-17 agents or abatacept were less common (4/18 and 1/18 respectively). Mean duration of biological agent exposure before vitiligo onset was 13.9 ± 16.5 months. Outcome was favourable for most patients (15/17) while maintaining the biological agent. Data were also collected for 18 patients (psoriasis N = 5, inflammatory rheumatic diseases N = 10, inflammatory bowel diseases N = 2, SAPHO N = 1) who had pre-existing vitiligo when treatment with a biological agent started (TNFα inhibitors N = 15, ustekinumab N = 1, rituximab N = 1, tocilizumab N = 1). Vitiligo progressed in seven patients and was stable or improved in eight cases. Vitiligo may thus emerge and/or progress during treatment with various biological agents, mainly TNFα inhibitors and could be a new paradoxical skin reaction. De novo vitiligo displays a favourable outcome when maintaining the biological agent, whereas the prognosis seems worse in cases of pre-existing vitiligo. © 2016 European Academy of Dermatology and Venereology.

    Purpose Vitiligo prevalence and its associated comorbidities rate have been reported variably among different populations. We aimed to determine the prevalence of vitiligo in Korea along with the baseline rate of comorbidities and compared the risks to the general population using hospital visit information of the total population in Korea. Materials and Methods We assessed demographic characteristics of vitiligo patients in Korean population from 2009 to 2011 in a nationwide data from Health Insurance Review Assessment Service. Patients who had at least one visit to Korea's primary, secondary, or tertiary referral hospitals with International Classification of Diseases, 10th Revision, Clinical Modification diagnosis code for vitiligo were identified. As a supplementary study, comorbidities associated with vitiligo were selected for further review to calculate relative risks compared to the general population. Results The annual prevalence of vitiligo determined by hospital-visiting rate in Korea was 0.12% to 0.13% over a three year period. In sync with other previous epidemiological studies, there was bimodal distribution among the age groups and no difference between genders. Also, vitiligo in Korean population was associated with various autoimmune/non-autoimmune diseases such as thyroiditis, atopic dermatitis, and psoriasis. Conclusion This study was by far the most comprehensive review on prevalence of vitiligo using a data of total population in Korea. The prevalence is within a range of those reported in previous literatures, and increased risk of comorbidities such as thyroid diseases and psoriasis in vitiligo might aid clinicians in the initial work up of vitiligo patients and concurrent follow ups.

    Low vitamin D levels have been associated with several autoimmune diseases. Vitiligo could be associated with low vitamin D levels. To determine the level of serum vitamin D in vitiligo patients compared to controls and reveal the possible association of vitamin levels with the pathogenesis of vitiligo. A case-controlled study was conducted. After excluding factors that may affect serum vitamin D levels, blood samples were taken from vitiligo patients and controls. The association between vitamin D levels and various vitiligo subgroups (duration of vitiligo, site of onset, age, etc) was measured and correlated. A total of 150 vitiligo patients, 90 (60%) males with a mean age of 30.6 ± 11.4 years, were recruited. The study also had 150 age- and gender-matched vitiligo-free control subjects. There was no significant difference in median serum vitamin D levels between the cases and the controls (P = .25). The serum levels of vitamin D of the vitiligo patients were found to be lower in males (P = .01), the younger age group (P = .01), and patients not treated with ultraviolet (UV) treatment (P = .01). There is no difference between the vitamin D levels of the vitiligo patients and the control subjects. However, deficiency of 25(OH)D levels within the vitiligo subgroups may be linked to younger age, male gender, short duration of vitiligo, and non-use of phototherapy. © The Author(s) 2015.

    Vitiligo is a chronic disease characterized by the dysfunction or destruction of melanocytes with secondary depigmentation. The aim of the present study was to determine the prevalence of vitiligo associated with autoimmune rheumatic diseases. The clinical records from a 10-year database of patients with rheumatic diseases and associated vitiligo was analysed, with one group of patients having autoimmune rheumatic disease and another non-autoimmune rheumatic disease. Available serum samples were used to assess the anti-melanocyte antibodies. A total of 5,251 individual clinical files were archived in the last 10 years, and these patients underwent multiple rheumatology consultations, with 0.3% of the group presenting with vitiligo. The prevalence of vitiligo in the autoimmune rheumatic disease group was 0.672%, which was mainly associated with lupus and arthritis. However, patients with more than one autoimmune disease had an increased relative risk to develop vitiligo, and anti-melanocyte antibodies were positive in 92% of these patients. By contrast, the prevalence was 0.082% in the group that lacked autoimmune rheumatic disease and had negative autoantibodies. In conclusion, the association between vitiligo and autoimmune rheumatic diseases was relatively low. However, the relative risk increased when there were other autoimmune comorbidities, such as thyroiditis or celiac disease. Therefore, the presence of multiple autoimmune syndromes should be suspected.

    Existing therapies for vitiligo are limited in efficacy and can be associated with undesirable side effects. Topical Janus kinase inhibitors may offer a new therapeutic option for vitiligo. We sought to assess the role of topical ruxolitinib 1.5% cream, a Janus kinase inhibitor, in vitiligo treatment. This 20-week, open-label, proof-of-concept trial of twice-daily topical ruxolitinib 1.5% cream was conducted in 12 patients with a minimum of 1% affected body surface area of vitiligo. The primary outcome was percent improvement in Vitiligo Area Scoring Index from baseline to week 20. Of 12 patients screened, 11 were enrolled and 9 completed the study (54.5% men; mean age, 52 years). Four patients with significant facial involvement at baseline had a 76% improvement in facial Vitiligo Area Scoring Index scores at week 20 (95% confidence interval, 53-99%; P = .001). A 23% improvement in overall Vitiligo Area Scoring Index scores was observed in all enrolled patients at week 20 (95% confidence interval, 4-43%; P = .02). Three of 8 patients responded on body surfaces and 1 of 8 patients responded on acral surfaces. Adverse events were minor, including erythema, hyperpigmentation, and transient acne. Limitations of the study include the small sample size and open-label study design. Topical ruxolitinib 1.5% cream provided significant repigmentation in facial vitiligo and may offer a valuable new treatment for vitiligo. Copyright © 2017 American Academy of Dermatology, Inc.

    Vitiligo is a common chronic acquired disease of pigmentation whose etiology is unknown, which usually occurs with asymptomatic whitish patch or macule. Although several hypotheses have been proposed in the literature, the leading theory is still the auto-immune etiology linked to specific genetic mutations. Vitiligo can also be associated with several autoimmune diseases, including autoimmune thyroid diseases, alopecia areata, and halo nevi. Sensorineural hearing loss was reported in several vitiligo patients due to a reduction in the number of melanocytes contained in the membranous labyrinth of the inner ear. Because of its complexity, several therapeutic options are available to treat this systemic disease. Copyright © 2015 Elsevier B.V. All rights reserved.

    Vitiligo is an acquired pigmentary disorder of the skin of unknown aetiology. The autocytotoxic hypothesis suggests that melanocyte impairment could be related to increased oxidative stress. Evidences have been reported that in vitiligo oxidative stress might also be present systemically. We used the comet assay (single cell alkaline gel electrophoresis) to evaluate DNA strand breaks and DNA base oxidation, measured as formamidopyrimidine DNA glycosylase (FPG)-sensitive sites, in peripheral blood cells from patients with active vitiligo and healthy controls. The basal level of oxidative DNA damage in mononuclear leukocytes was increased in vitiligo compared to normal subjects, whereas DNA strand breaks (SBs) were not changed. This alteration was not accompanied by a different capability to respond to in vitro oxidative challenge. No differences in the basal levels of DNA damage in polymorphonuclear leukocytes were found between patients and healthy subjects. Thus, this study supports the hypothesis that in vitiligo a systemic oxidative stress exists, and demonstrates for the first time the presence of oxidative alterations at the nuclear level. The increase in oxidative DNA damage shown in the mononuclear component of peripheral blood leukocytes from vitiligo patients was not particularly severe. However, these findings support an adjuvant role of antioxidant treatment in vitiligo.

    Full Text Available Abstract Background Vitiligo is an acquired depigmenting disorder due to destruction of melanocytes. Although many theories have been suggested for its pathogenesis, the role of autoimmunity is the most popular one. The association of vitiligo with autoimmune thyroid diseases and the increased prevalence of autoantibodies including thyroid autoantibodies in vitiligo favor this role. Our objective was to compare the frequency of thyroid peroxidase antibody (anti-TPO in vitiligo patients with healthy subjects in Iran. Methods Ninety-four cases of vitiligo (46 female and 48 male and 96 control subjects (49 female and 47 male were enrolled in this controlled study. Patients with known thyroid disease, history of thyroid surgery and those receiving thyroid medications were not included. The two groups were matched regarding gender and age. The demographic data, symptoms related to thyroid diseases and results of skin and thyroid examinations were recorded in a questionnaire for each subject. Thyroid function tests including free T3, free T4 and TSH-IRMA were performed. Anti-TPO levels were assessed as well. The collected data were analyzed by SPSS version-11 in vitiligo patients and subgroups according to gender, age, extent, and duration of the disease compared with the control group. Results Anti-TPO was detected in 17 (18.1% of patients affected by vitiligo, while this figure was 7 (7.3% in the control group; the difference was significant with p-value The difference of the frequency of anti-TPO was not significant regarding the duration and extent of vitiligo. In addition, there was no significant difference in the levels of free T3, free T4, and TSH in vitiligo patients compared with the control group. Conclusion According to our study, anti-TPO was shown to be significantly more common in vitiligo patients especially in young women, compared with control group. As this antibody is a relatively sensitive and specific marker of autoimmune thyroid

    Full Text Available The increasing incidence of vitiligo in this part of the world (4.25%, prompted us to study 5000 fresh vitiligo patients. Several triggering factors were elicitable. Malnutrition and intake of junk food were very common in childhood vitiligo. Intercurrent infections as well as intake of antibotics were also significant, immediately preceding the development of depigmented patches in younger age group. Genetic predisposition was uncommon. Autoimmune disorders were infrequent and usually accompanied late onset vitiligo. For management, vitiligo was classified into VI (active, V2 (quiescent and V3 (improving stages. The therapy administered varied in each stage. As a common denominator, all out efforts were made to eliminate possible trigger factors in individual cases throughout the period of treatment, and building the general health to prevent recurrence in future. The study strongly points out that vitiligo is a multifactorial disorder. It can be effectively managed after each patient is individually assessed. Elimination of possible triggering factors may form the mainstay of vitiligo therapy along with controlled pharmacological intervention. The improvement of general resistance of body may bring spontaneous repigmentation.

    Full Text Available Surgical treatment for vitiligo has been ever evolving. Each surgical modality has its own benefits and limitations. Miniature punch grafting is the most extensively performed surgery, which gives good results in stable vitiligo. Herein we report an unusual type of repigmentation observed after minipunch grafting in a patient of stable vitiligo, which resembled target-like lesions with a "perigraft halo" surrounding individual grafts. Such pigment spread occurred despite the use of 0.5 mm larger graft from the donor site.

    Full Text Available Background : Vitiligo is a disease that significantly impairs quality of life. Previous studies have shown that vitiligo has an impact that may not correlate with the size and extent of depigmentation, indicating a need for an independent measure of the psychosocial burden. Aims : To develop a rating scale to assess the psychosocial impact of vitiligo. Methods : The study was undertaken in three broad phases: item generation, pre- and pilot testing, and test administration. Items were generated largely from a qualitative study using semi-structured interviews of patients. Face and content validity were assessed through pre- and pilot testing in 80 patients and the final version was administered to 100 patients who also received the Dermatology Life Quality Index (DLQI and the Skindex-16. Each patient also underwent a physician global assessment (PGA of the impact of vitiligo. Test-retest reliability was assessed in 20 patients. Results: Of 72 items initially generated for the scale, 27 were retained in the final version. Subjects were able to comprehend the items and took about 5-7 min to complete the instrument. The scale was internally consistent (Cronbach′s α = 0.85. Scores on the scale correlated moderately well with the DLQI and the Skindex (Spearman rank correlation: 0.51 and 0.65, respectively. The scale was able to discriminate between patients having mild and those having moderate and severe impact as assessed by PGA. The test-retest reliability coefficient (Spearman rank correlation was 0.80. Conclusion: The Vitiligo Impact Scale appears to be a valid measure of the psychosocial impact of vitiligo and this instrument may be useful both in the clinic and in clinical trials.

    Background Vitiligo is a common skin disorder, characterized by progressive skin de-pigmentation due to the loss of cutaneous melanocytes. The exact cause of melanocyte loss remains unclear, but a large number of observations have pointed to the important role of cellular immunity in vitiligo pathogenesis. Methodology/Principal Findings In this study, we characterized T cell and inflammation-related dermal dendritic cell (DC) subsets in pigmented non-lesional, leading edge and depigmented lesional vitiligo skin. By immunohistochemistry staining, we observed enhanced populations of CD11c+ myeloid dermal DCs and CD207+ Langerhans cells in leading edge vitiligo biopsies. DC-LAMP+ and CD1c+ sub-populations of dermal DCs expanded significantly in leading edge and lesional vitiligo skin. We also detected elevated tissue mRNA levels of IL-17A in leading edge skin biopsies of vitiligo patients, as well as IL-17A positive T cells by immunohistochemistry and immunofluorescence. Langerhans cells with activated inflammasomes were also noted in lesional vitiligo skin, along with increased IL-1ß mRNA, which suggest the potential of Langerhans cells to drive Th17 activation in vitiligo. Conclusions/Significance These studies provided direct tissue evidence that implicates active Th17 cells in vitiligo skin lesions. We characterized new cellular immune elements, in the active margins of vitiligo lesions (e.g. populations of epidermal and dermal dendritic cells subsets), which could potentially drive the inflammatory responses.

    Associations between vitiligo and thyroid diseases have been reported repeatedly. We investigated the associations between vitiligo and overt autoimmune thyroid diseases and thyroid cancer using the Korean National Health Insurance claims database. 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. 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. Individual clinical information was not available, and the homogeneous population may limit the generalizability of the results. Vitiligo was significantly associated with overt autoimmune thyroid diseases and overt thyroid cancer. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    2014-01-01

    Full Text Available Introduction: Vitiligo is an acquired depigmentary condition caused by inactivation or destruction of melanocytes in epidermis and hair follicle. Worldwide incidence of 1% has been reported; similar to various dermatological clinics in India. Widespread prejudice, ignorance, taboos, lack of scientific appraisal, and confusion of vitiligo with leprosy makes it an immense psychological stress. Aim: To know the clinical profile of vitiligo patient with associated cofactors. Materials and Methods: Total 1,010 patients of vitiligo attended in outpatient department at Shree Krishna Hospital (SKH and Matar camp, Gujarat over 1 year period from August 2011 to July 2012 were included in this study. Detail history and clinical examination of patients were done. Results: Out of 1,010 patients 57.3% were females and 42.7 % were males. Most cases developed vitiligo by 2 nd decade of life. Progressive course was found in 60.9 % of patients. Vitiligo vulgaris (57.8% was most common morphological type. Most common site of onset (41.5% and involvement (75.7% was lower limb. Family history was present in 20.4%. Conclusions: Vitiligo constitutes important dermatological disease especially in India. The data suggest that local epidemiological behavior of vitiligo need not be the same across different regions. Vitiligo differs substantially in various clinical aspects.

    Full Text Available Context: Epidemiological studies have shown that vitiligo is a complex trait, involving combinations of pathogenic effects of multiple susceptibility genes as well as environmental risk factors. Aim: To observe whether consanguinity increased the incidence of vitiligo in Saudi patients from Arar. Patients and Methods: This study included 69 Saudi patients with vitiligo and their families. These patients, selected from the experience specialist dermatology center in Arar, from April 2011 to 2012, were interviewed by a dermatologist to confirm the diagnosis and complete a questionnaire. Results: A total of 69 patients, 40 males and 29 females were selected. Their mean age was 34.5 ± 11.8 years with the median age of 23 years. The mean age at onset of disease was 27.9 ± 12.9 years. The mean duration of the disease was 9.7 ± 5.3 years. The frequency of focal, vulgaris, universal, and acrofacial subtypes was 22 (31.9%, 21 (30.4%, 8 (11.6%, and 18 (26.1%, respectively. A positive family history of vitiligo was obtained in 45 (65.2% cases. A comparison of the frequency of vitiligo among siblings in relation to the general population was more in accord with the multifactorial model. Conclusion: Consanguinity in marriage increases the incidence of the disease. Therefore, genetic counseling and premarital examination would be important contributions to lower the prevalence of vitiligo.

    Full Text Available A giant congenital melanocytic nevus represents a rare condition. The halo phenomenon may be seen in congenital or acquired melanocytic nevi. In the literature, association of halo nevus and giant congenital melanocytic nevus is rare and the association of both with vitiligo even more rare. A 75-yearold woman at first consultation complained of a hyperchromic bluish-brown hairy macula on the lower back, buttocks and thighs present since birth and an achromic halo of onset three years ago. The histological features were consistent with congenital melanocytic nevus and halo nevus, respectively. After two years the patient developed achromic areas in normal skin, histologically consistent with vitiligo. The authors emphasize the rarity of this triple combination, the patient's age and the absence of malignant degeneration to date.Nevo melanocitico congênito gigante constitui uma condição rara. O fenômeno halo pode ser observado em nevos melanocíticos congênitos ou adquiridos. Na literatura a associação nevo halo e nevo melanocítico congênito gigante é rara e a associação de ambos com vitiligo ainda mais rara. Mulher de 75 anos que à primeira consulta apresentava mácula hipercrômica castanho-azulada pilosa na região lombar, nádegas e coxas desde o nascimento e halo acrômico de aparecimento há 3 anos. Os histológicos foram compatíveis com nevo melanocítico congênito e nevo halo respectivamente. Após dois anos evoluiu com áreas de acromia à distância, com histológico de vitiligo. Os autores ressaltam a raridade desta tripla associação; a idade da paciente e a ausência de degeneração maligna até o presente momento.

    2016-08-01

    Full Text Available Introduction : Vitiligo is a common acquired pigmentary skin disorder. Vitamin D is responsible for skin pigmentation, increases tyrosinase activity and melanogenesis, and exhibits immunoregulatory functions. Low levels of vitamin D are associated with many autoimmune diseases, including systemic lupus, diabetes mellitus, rheumatoid arthritis, multiple sclerosis and alopecia areata. Few reports have evaluated serum vitamin D levels in vitiligo patients, and their results are conflicting. Aim : To evaluate serum vitamin D levels of vitiligo patients and compare the results with controls. Material and methods : In total, 50 vitiligo patients and 47 controls were enrolled in the study. Vitamin D levels were measured from blood samples. Group comparisons were performed using appropriate statistical methods. Results : The patients had lower serum vitamin D levels than the controls, but this difference was not significant (p = 0.570. Conclusions : It remains unknown whether vitamin D deficiency causes vitiligo. Larger controlled studies are required to prove whether low circulating vitamin D is a causative factor in vitiligo.

    Case series Patient: — Final Diagnosis: — Symptoms: Skin lesions Medication: — Clinical Procedure: — Specialty: Dermatology Objective: Unusual or unexpected effect of treatment Background: Vitiligo, also known as leukoderma, is an autoimmune skin condition that results in the loss of melanin pigment. Vitiligo is not a rare condition but is difficult to treat and is associated with psychological distress. Case Reports: A series of 14 cases of vitiligo are presented that were treated with individualized homeopathic remedies that were based on plant, animal, or mineral compounds. There were 13 women and one man in the case series, with a mean age 29.8 years, and a mean follow-up from treatment of 58 months. The mean time between the onset of the appearance of vitiligo and the first consultation at our clinic was 96 months. Homeopathic treatment for patients is holistic and was performed on an individualized basis as described in this case series. Photographic images of the skin are presented before and after treatment. Conclusions: In 14 patients with vitiligo treated with individualized homeopathy, the best results were achieved in the patients who were treated in the early stages of the disease. We believe that homeopathy may be effective in the early stages of vitiligo, but large controlled clinical studies are needed in this area. PMID:29196612

    Zn, Cu, Fe, Pb, Mn, Co, Ag, Ca, and Mg were estimated in hair, fingernails and epidermis of vitiligo patients by atomic absorption spectroscopy. There has been a significant reduction in the concentration of trace metals in the studied sites. It seems that any speculation on the role of trace elements in vitiligo would have to take into account the structural defect which underlies the absence of melanin

    Background Vitiligo is characterized by the death of melanocytes in the skin. This is associated with the presence of T cell infiltrates in the lesional borders. However, at present, there is no detailed and systematic characterization on whether additional cellular or molecular changes are present inside vitiligo lesions. Further, it is unknown if the normal appearing non-lesional skin of vitiligo patients is in fact normal. The purpose of this study is to systematically characterize the molecular and cellular characteristics of the lesional and non-lesional skin of vitiligo patients. Methods and Materials Paired lesional and non-lesional skin biopsies from twenty-three vitiligo patients and normal skin biopsies from sixteen healthy volunteers were obtained with informed consent. The following aspects were analyzed: (1) transcriptome changes present in vitiligo skin using DNA microarrays and qRT-PCR; (2) abnormal cellular infiltrates in vitiligo skin explant cultures using flow cytometry; and (3) distribution of the abnormal cellular infiltrates in vitiligo skin using immunofluorescence microscopy. Results Compared with normal skin, vitiligo lesional skin contained 17 genes (mostly melanocyte-specific genes) whose expression was decreased or absent. In contrast, the relative expression of 13 genes was up-regulated. The up-regulated genes point to aberrant activity of the innate immune system, especially natural killer cells in vitiligo. Strikingly, the markers of heightened innate immune responses were also found to be up-regulated in the non-lesional skin of vitiligo patients. Conclusions and Clinical Implications As the first systematic transcriptome characterization of the skin in vitiligo patients, this study revealed previously unknown molecular markers that strongly suggest aberrant innate immune activation in the microenvironment of vitiligo skin. Since these changes involve both lesional and non-lesional skin, our results suggest that therapies targeting

    2007-11-01

    Full Text Available Dermatitis herpetiformis (DH is a rare immunobullous disorder of the skin that is associated with gluten hypersensitivity. Subepidermal IgA-type antibody deposition against tissue transglutaminase leads to dense neutrophilic microabscess and eventually into vesicles in dermal papillae, which may occasionally merge into bullae. Being a subepidermal vesiculobullous disorder, DH is frequently associated with postinflammatory pigmentary changes, particularly hypopigmentation. However, the association of DH with true vitiligo is extremely rare. Here, we report a 21-year-old male with vitiligo and comorbid DH, and review the literature. This new case had severely pruritic, papular and papulovesicular lesions that were localized symmetrically and partly confined to the pre-existing vitiliginous areas. The skin biopsy specimen taken from an erythematous papule on the elbow showed characteristic findings of DH and vitiligo. Direct immunofluorescence microscopy of the perilesional skin revealed granular IgA deposition of dermal papillae. There are only 10 reports in the literature of DH and vitiligo comorbidity.

    2012-01-01

    Abstract Tumor Necrosis Factor (TNF)-α, is a paracrine inhibitor of melanocytes, which plays a critical role in the pathogenesis of several autoimmune diseases including vitiligo, as abnormal immune responses have frequently been observed in vitiligo patients. Moreover, vitiligo patients show higher lesion levels of TNF-α. Genetic polymorphisms in the promoter region of TNF-α are involved in the regulation of its expression. The present study explores TNF-α promoter polymorphisms and correlates them with TNF-α transcript and protein levels in vitiligo patients and controls of Gujarat along with its effect on disease onset and progression. PCR-RFLP technique was used for genotyping of these polymorphisms in 977 vitiligo patients and 990 controls. TNF-α transcript and protein levels were measured by Real time PCR and ELISA respectively. The genotype and allele frequencies for the investigated polymorphisms were significantly associated with vitiligo patients. The study revealed significant increase in TNF-α transcript and protein levels in vitiligo patients compared to controls. In particular, haplotypes: AATCC, AACCT, AGTCT, GATCT, GATCC and AGCCT were found to increase the TNF-α levels in vitiligo patients. Analysis of TNF-α levels based on the gender and disease progression suggests that female patients and patients with active vitiligo had higher levels of TNF-α. Also, the TNF-α levels were high in patients with generalized vitiligo as compared to localized vitiligo. Age of onset analysis of the disease suggests that the haplotypes: AACAT, AACCT, AATCC and AATCT had a profound effect in the early onset of the disease. Moreover, the analysis suggests that female patients had an early onset of vitiligo. Overall, our results suggest that TNF-α promoter polymorphisms may be genetic risk factors for susceptibility and progression of the disease. The up-regulation of TNF-α transcript and protein levels in individuals with susceptible haplotypes advocates

    Full Text Available It has been defined that coeliac disease is associated with most of the autoimmune diseases including psoriasis and vitiligo. Here, a 26-year-old woman who was diagnosed palmoplantar pustular psoriasis and already had coeliac disease and vitiligo is reported. According to our opinions, this is the first report describing the development of these three disorders in one patient, even though vitiligo, psoriasis and coeliac disease are common disorders, and the coexistence of the two of them has been previously reported in the literature. This case has been presented to emphasize the importance of considering and inquiring the possible coeliac disease in chronic and autoimmune dermatoses, although psoriasis and vitiligo may have coincidental associations with coeliac disease.

Vitiligo is caused by the destruction of melanocytes and results in the appearance of white patches on any part of the body, while alopecia areata is characterized by patchy hair loss primarily on the scalp, but may also involve other areas as well. At first glance, the two diseases appear to be quite different, targeting different cell types and managed using different treatment approaches. However, the immune cell populations and cytokines that drive each disease are similar, they are closely associated within patients and their family members, and vitiligo and alopecia areata have common genetic risk factors, suggesting that they share a similar pathogenesis. Like apples and oranges, vitiligo and alopecia areata have some obvious differences, but similarities abound. Recognizing both similarities and differences will promote research into the pathogenesis of each disease, as well as the development of new treatments. PMID:24131336

    Vitiligo is a skin disorder in which white patches of depigmentation appear on different parts of the body. Usually, patients come to hospitals or clinics to have their vitiligo conditions assessed. This can be very tiring to the patients, as vitiligo treatments usually take a relatively long period of time, which can range from months to years. To address this challenge, we present in this paper a prototype of an Android-based mobile application called Vi-DA, which stands for Vitiligo Diagnostic Assistance. Vi-DA consists of three subsystems, which are user sign-up subsystem, camera and image analysis subsystem, and progress report subsystem. The mobile application was developed in Java programming language and uses MySQL as the database system. Vi-DA adopts a vitiligo segmentation algorithm to segment input image into normal skin area, vitiligo skin area, and non-skin area. Results showed that Vi-DA gave comparable results to the previous system implemented in Matlab. User acceptance testing results also showed that all respondents agreed on the usefulness of the system and agreed to use Vi-DA again in the future. Vi-DA benefits both dermatologists and patients as not only a computer-aided diagnosis (CAD) tool but also as a smart application that can be used for self-assessment at home.

    BACKGROUND Vitiligo, also known as leukoderma, is an autoimmune skin condition that results in the loss of melanin pigment. Vitiligo is not a rare condition but is difficult to treat and is associated with psychological distress. CASE REPORT A series of 14 cases of vitiligo are presented that were treated with individualized homeopathic remedies that were based on plant, animal, or mineral compounds. There were 13 women and one man in the case series, with a mean age 29.8 years, and a mean follow-up from treatment of 58 months. The mean time between the onset of the appearance of vitiligo and the first consultation at our clinic was 96 months. Homeopathic treatment for patients is holistic and was performed on an individualized basis as described in this case series. Photographic images of the skin are presented before and after treatment. CONCLUSIONS In 14 patients with vitiligo treated with individualized homeopathy, the best results were achieved in the patients who were treated in the early stages of the disease. We believe that homeopathy may be effective in the early stages of vitiligo, but large controlled clinical studies are needed in this area.

    Full Text Available Background: Targeted ultraviolet B (T-UVB phototherapy in vitiligo is usually administered twice or thrice a week on non-consecutive days. It is difficult for many patients to adhere to this regimen, forcing them to discontinue treatment. Aim: The study aimed to compare the efficacy of twice-weekly and once-weekly targeted ultraviolet B phototherapy regimens in vitiligo. Methods: Sixty patients with non-segmental vitiligo on the face, neck or trunk were divided into two groups of 30 patients each. The patients in group A received targeted ultraviolet B twice weekly, while those in group B received targeted ultraviolet B once weekly. Repigmentation was monitored and graded as excellent (≥75% repigmentation, good (50−74% repigmentation and poor (<50% repigmentation. The extent of repigmentation at each body site (primary outcome measure, the number of doses required for initiation of pigmentation, and the cumulative dose of targeted ultraviolet B administered was calculated and compared between both groups. Results: A total of 90 lesions (48 in the twice weeklygroup and 42 in the once weekly group were treated on the face, neck and trunk. Excellent results were obtained in 62.5% (30/48 of lesions treated twice weekly, and 64.3% (27/42 in lesions treated once weekly. The mean number of doses required for initiation of pigmentation was 4.69 in the twice weekly group, and 4.35 in the once weekly group. The patients in the twice weekly group received a mean cumulative dose of 8.26 J/cm 2, while the once weekly group received 7.69 J/cm 2. No statistically significant differences were observed between the two groups with respect to the outcome, with respect to the total repigmentation, the number of doses till onset of pigmentation, as well as the cumulative dose of targeted UVB. Conclusion: Once-weekly targeted ultraviolet B phototherapy appears to be as efficacious as the twice-weekly regimen in vitiligo.

    Vitiligo is a common chronic skin disorder characterized by loss of epidermal melanocytes and progressive depigmentation. Vitiligo has complex immune, genetic, environmental, and biochemical causes, but the exact molecular mechanisms of vitiligo development and progression, particularly those related to metabolic control, are poorly understood. In this study we characterized the human vitiligo cell line PIG3V and the normal human melanocyte line HEM-l by RNA sequencing, targeted metabolomics, and shotgun lipidomics. Melanocyte-enriched microRNA-211, a known metabolic switch in nonpigmented melanoma cells, was severely down-regulated in vitiligo cell line PIG3V and skin biopsy samples from vitiligo patients, whereas its predicted targets PPARGC1A, RRM2, and TAOK1 were reciprocally up-regulated. microRNA-211 binds to PGC1-α 3' untranslated region locus and represses it. Although mitochondrial numbers were constant, mitochondrial complexes I, II, and IV and respiratory responses were defective in vitiligo cells. Nanoparticle-coated microRNA-211 partially augmented the oxygen consumption rate in PIG3V cells. The lower oxygen consumption rate, changes in lipid and metabolite profiles, and increased reactive oxygen species production observed in vitiligo cells appear to be partly due to abnormal regulation of microRNA-211 and its target genes. These genes represent potential biomarkers and therapeutic targets in human vitiligo. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    Vitiligo iridis refers to focal areas of iris atrophy as sequelae of small pox infection. We report a series of patients with unilateral vitiligo iridis, some of whom presented with secondary open-angle glaucoma. Three patients with vitiligo iridis underwent a comprehensive ophthalmic examination including intraocular pressure (IOP) measurement, slit lamp biomicroscopy, gonioscopy, and fundus evaluation. Patients' facial features were also documented and photographed. All patients were in their sixth decade. Two out the three had elevated IOP (52 mm Hg and 36 mm Hg) in the same eye as vitiligo iridis, at initial presentation. Gonioscopy showed patchy iris hyperpigmentation and fundus evaluation showed glaucomatous optic disc changes in the involved eye. One patient responded favourably to topical antiglaucoma medications, whereas the other was taken up for combined phacoemulsification-trabeculectomy with good results. The third patient had normal IOP in the involved eye. All three patients gave a history of small pox in childhood and had pitted facial scars typical of previous small pox infection. Vitiligo iridis may be associated with the secondary glaucoma as a long-term sequelae of small pox. It may be prudent to periodically follow-up such patients for development of raised IOP in the future.

    Late-onset vitiligo, defined as being aged 50 years and above at the point of clinical onset, remains poorly characterized till now. This study aims to describe the clinical characteristics and treatment response of patients with late-onset vitiligo. We retrospectively reviewed the case records of all patients diagnosed with late-onset vitiligo, from January 1, 2010 to December 31, 2014. Information obtained included patient demographics, characteristics of vitiligo and treatment responses. Of the 3128 patients diagnosed with vitiligo over the 5-year period, 461 (14.7%) had late-onset disease. The study had more females (n = 260, 56.4%) than males, with an average onset age of 59.4 ± 7.4 years. Majority of patients were Chinese (n = 308, 66.8%) and 45 (9.8%) patients had an associated autoimmune disease. Focal vitiligo, defined as the localized presence of depigmented patches, was most common (n = 209, 45.3%). Treatment response was evaluated in 359 patients, of which 216 received monotherapy (topical creams: n = 210, 97.2%; phototherapy: n = 6, 2.8%) and 143 received both modalities. Fifty six (15.6%) patients received oral steroids. Patients who were treated with both topical creams and phototherapy yielded better clinical responses compared to those on monotherapy (P 50% return of pigmentation compared to baseline (vs. n = 66, 30.6% in the monotherapy group). The choice of phototherapy (targeted, narrowband ultraviolet B or psoralen + ultraviolet A) did not significantly affect clinical response (P = 0.774). This study is limited by its retrospective nature, the nonstandardized documentation resulting in the inability to determine disease progression and associated metabolic comorbidities and also by the gradual loss to follow-up of patients. Late-onset vitiligo is not uncommon and tends to be of the focal vitiligo subtype. Nonsegmented vitiligo is more prevalent than segmental vitiligo. Combination therapy with topical medications and phototherapy is superior

    Melanoma-associated vitiligo is the best-studied example of the linkage between tumor immunity and autoimmunity. Although vitiligo is an independent positive prognostic factor for melanoma patients, the autoimmune destruction of melanocytes was long thought to be merely a side effect of robust anti-tumor immunity. However, new data reveal a key role for vitiligo in supporting T cell responses to melanoma. This research perspective reviews the history of melanoma-associated vitiligo in patients, the experimental studies that form the basis for understanding this relationship, and the unique characteristics of melanoma-specific CD8 T cells found in hosts with vitiligo. We also discuss the implications of our recent findings for the interpretation of patient responses, and the design of next-generation cancer immunotherapies. PMID:21911918

    The insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme (ACE) gene is associated with vitiligo in the Indians and Koreans, but not in those of English or Turkish background. We investigated the ACE (I/D) polymorphism in vitiligo patients for the first time in Egypt and compared serum ACE levels between vitiligo patients and controls. The present study was carried out in 100 vitiligo patients (40 males and 60 females) and in 100 healthy controls of an Egyptian population using the polymerase chain reaction genotyping method. The ACE genotype and allele frequency was significantly different between vitiligo patients and controls. Our results revealed a significant increase in the frequency of the ACE I allele (p=0.002; odds ratio: 1.99; 95% confidence intervals: 1.207-3.284) with an overrepresentation of I/D genotype in the vitiligo patient group. Furthermore, there was a significant difference between the segmental, nonsegmental, and focal vitiligo in ACE gene genotype distribution. Serum ACE levels were significantly increased in vitiligo patients compared to controls (p=0.034). This study suggests that, for the first time, ACE gene polymorphism confers susceptibility to vitiligo in the Egyptian population.

    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 vitiligo and HT that might represent an immunological basis for secondary HT associated with vitiligo.

    Cytokeratins (CK) belong to the family of intermediate filament proteins, and among them specific epithelial keratins are considered markers for stem cells activation. This study aims to investigate the expression of CK15 and CK19 as possible stem cell markers in vitiligo during phototherapy. The study was conducted on vitiligo patients receiving narrow-band ultraviolet therapy. Immunohistochemical staining for CK15 and CK19 was carried out, and clinical follow-up continued for 4 weeks. Of 28 patients, CK15 expression was demonstrated in 17 cases (61%) while CK19 expression was demonstrated in 11 cases (39%). Cells expressing positive staining were demonstrated in follicular and interfollicular epithelium. Expression was clearly demonstrated in patients younger than 20 years old, with shorter disease duration, with disease stability, and with normally pigmented hairs. Expression of cytokeratins was significantly correlated to improvement of vitiligo lesions. CK15 and CK19 are expressed in vitiligo during UV repigmentation in the follicular and interfollicular epithelium. This expression of cytokeratins was significantly correlated to improvement and can be considered valuable tool to monitor stem cells stimulation for the sake of the repigmentation process in vitiligo. © 2016 Wiley Periodicals, Inc.

    Vitiligo is an acquired depigmenting disease characterized by circumscribed depigmenting macules devoid of identifiable melanocytes. The disease has uncertain aetiopathogenesis. The aim of this research is to estimate the level of superoxide dismutase (SOD) and catalase (CAT) as antioxidants and Nitric oxide and superoxide anion as oxidants in vitiligo patients and evaluate the clinical effectiveness of narrow band UVB (NB-UVB-311) as a method of treatment and repairing the oxidative stress-induced damage. This study included twenty vitiligo patients and fifteen-age and sex matched control. There was statistically significant increase in the levels of SOD in active vitiligo lesions compared to control (P<0.001). There was statistically significant decrease in the level of CAT in vitiligo skin lesions compared to skin of control. After using NB-UVB- 311 the level of SOD was significantly decreased and CAT level was significantly increased (P<0.001). There was statistically significant increase in the level of nitric oxide and superoxide in vitiligo patients compared to control. After using NB-UVB-311 as treatment, the level of nitric oxide and superoxide anion was significantly decreased (P<0.001) in vitiligo patients. These results provide some evidence regarding the oxidant /antioxidant balance in vitiligo patients and the positive role of narrow band UVB- 311 as a treatment of vitiligo

    Vitiligo is unsightly on darkly pigmented skin and leads important stigmatization because of the mix-up with leprosy. We analyzed retrospectively the epidemiological and clinical patterns of vitiligo on darkly pigmented skin between 1988 and 2008 in the Department of Dermatology in Cotonou (Benin). The diagnosis was made based on the clinical characteristics of vitiligo. Two hundred and forty-six patients were seen, representing 0.9% of new consultations. The gender ratio was 1 : 1, and the mean age of patients was 25.9 years. The mean duration of the lesions was 30.9 months. Among the 246 patients, an associated pathology was found in 26% of cases. These included atopy (23.2%), diabetes (1.6%), thyroid disease (0.8%), and alopecia (0.4%). A family history of vitiligo was present in 1.2% of cases. The sites of the lesions were in descending order of frequency: head (60.6%), lower limbs (40.2%), upper limbs (33.3%), trunk (22.4%), genitals (13.0%), and neck (8.9%). On the head, the most common sites affected were the lips (65.1%), cheek (20.8%), and ears (16.8%). According to the different clinical forms, vitiligo was achromic (76%), speckled (12.6%), and trichromic (11.4%). Vitiligo vulgaris was the commonest form of the disease (52.4%), followed by localized vitiligo (36.2%), segmental vitiligo (9.8%), and vitiligo universalis (1.6%). Triggering factors were identified in 4.5% of patients. Our survey shows that the patterns of vitiligo are similar to that reported from other African countries with a few distinguishing particularities. © 2016 The International Society of Dermatology.

    Background Vitiligo and atopic dermatitis (AD) are common dermatological disorders which may cause significant psychological and social distress leading to impaired quality of life (QoL) in patients. Objective We evaluated the degree of psychological stress and impairment of QoL in vitiligo patients as compared with AD patients and normal controls (NCs). Methods A total of 60 patients from each group and 60 NCs were enrolled. Five questionnaires on depression (Beck depression inventory, BDI), state anxiety (SA) and trait anxiety (TA), interaction anxiousness (IAS), private body consciousness (PBC) and dermatologic QoL were used. Results The vitiligo patients had a significantly higher level of TA (pvitiligo groups, all of the indexes except body consciousness were higher in AD patients than in vitiligo patients: BDI (pvitiligo lesions was not a significant variable in the analysis of the contribution of clinical variables of vitiligo on psychological stress and QoL. Conclusion Vitiligo, which is not accompanied by any symptoms, involves less psychological impact than AD, which is accompanied by itching. Compared to NCs, however, the elevated general anxiety and body consciousness in patients with vitiligo suggests that they may be more concerned with the aggravation of hypopigmented patches than difficulties in social interactions.

    Vitiligo is a depigmenting skin disorder, with disappearance of functioning epidermal melanocytes. Aquaporin-3 (AQP-3) is an aquaglyceroporin expressed in epidermal keratinocytes, where it shares in regulating their proliferation and differentiation, and so it might affect melanocytes indirectly. So far, little is known regarding its possible role in vitiligo. This work aimed to study the changes in immunohistochemical expression of AQP-3 protein in vitiligo to detect its possible role in disease pathogenesis. Skin biopsies were taken from lesional skin of 30 vitiligo patients in addition to 20 normal controls. Epidermal immunohistochemical expression of AQP-3 was assessed as: +3 = strong expression, +2 = moderate, +1= weak and 0= negative expression. AQP-3 was significantly less expressed in vitiligo epidermis than control (PVitiligo Index of Disease Activity (r =-0.505, P=0.004). Reduced epidermal AQP-3 may have a role in impaired melanocyte survival in vitiligo, and might be a potential negative biological marker for vitiligo activity. Larger trials should further elucidate the effect of changes in epidermal AQP-3 expression in development of vitiligo, and that might pave the road for discovering new therapeutic modalities for the disease.

    Full Text Available Vitiligo is a rare side effect of carbamazepine whose exact mechanism is unknown. The aim of this report is to describe a single case of vitiligo induced by carbamazepine.The case was a patient with Bipolar I disorder whose medications were changed from valproate to carbamazepine and who developed vitiligo after a short while. We followed the case for about four years when he was rechallenged with carbamazepine.When depigmentation occurred, we immediately discontinued carbamazepine after which the depigmented areas improved gradually. About three years later, he received carbamazepine again, but depigmentation did not recur.Carbamazepine-induced vitiligo is not an absolute contraindication for the prescription of carbamazepine if other choices fail to respond or are not tolerated. The case has implications for the mechanism of medication induced vitiligo.

    Although genetics plays an essential role in the pathogenesis of vitiligo, vitiligo pathogenesis is still unclear. Our aim was to investigate the role of IFN-γ expression and polymorphism in vitiligo susceptibility and whether intercellular adhesion molecule-1 (ICAM-1), tumor necrosis factor (TNF)-α, and TNF-β play a role in vitiligo pathogenesis as important inflammatory parameters. Eighty-five patients with vitiligo and 90 controls were investigated for IFN-γ gene expression by quantitative real-time PCR and genotyped for IFN-γ +874T/A (rs2430561) and IFN-γ +2109A/G (rs1861494) gene polymorphisms by sequence-specific primer (SSP)-PCR and PCR-restriction fragment length polymorphism (RFLP), respectively. Serum levels of inflammatory parameters were measured using ELISA. Frequencies of the +874 TT genotype and T allele were significantly higher in patients with active vitiligo than in stable patients (P = 0.01 and 0.03, respectively). Calculation of odds ratio suggested a 1.7-fold increased risk of vitiligo in individuals having the TA haplotype. We observed overexpression of IFN-γ mRNA with elevated serum levels of IFN-γ, ICAM-1, TNF-α, and TNF-β in patients with vitiligo when compared with the control group (P = 0.001, for all). In addition, these levels were elevated in patients with active vitiligo compared with stable patients with vitiligo (P = 0.008, 0.006, 0.01, 0.01, and 0.03, respectively), which suggests the involvement of these cytokines in disease activity. In conclusion, IFN-γ is a promising immunological marker in vitiligo pathogenesis.

    Childhood vitiligo differs from adult-onset vitiligo for several features including increased incidence of the segmental variant, higher prevalence of halo nevi, and more common family history for autoimmune diseases and atopic diathesis. The major differential diagnoses are the postinflammatory hypomelanoses for nonsegmental vitiligo and nevus depigmentosus for segmental vitiligo. From a therapeutic standpoint, early awareness of the diagnosis seems to correlate with a good treatment outcome in this age group. Copyright © 2016 Elsevier Inc. All rights reserved.

    Genetic polymorphisms in TNFB are involved in the regulation of its expression and are found to be associated with various autoimmune diseases. The aim of the present study was to determine whether TNFB +252A/G (rs909253) and exon 3 C/A (rs1041981) polymorphisms are associated with vitiligo susceptibility, and expression of TNFB and ICAM1 affects the disease onset and progression. We have earlier reported the role of TNFA in autoimmune pathogenesis of vitiligo, and we now show the involvement of TNFB in vitiligo pathogenesis. The two polymorphisms investigated in the TNFB were in strong linkage disequilibrium and significantly associated with vitiligo. TNFB and ICAM1 transcripts were significantly increased in patients compared to controls. Active vitiligo patients showed significant increase in TNFB transcripts compared to stable vitiligo. The genotype-phenotype analysis revealed that TNFB expression levels were higher in patients with GG and AA genotypes as compared to controls. Patients with the early age of onset and female patients showed higher TNFB and ICAM1 expression. Overall, our findings suggest that the increased TNFB transcript levels in vitiligo patients could result, at least in part, from variations at the genetic level which in turn leads to increased ICAM1 expression. For the first time, we show that TNFB +252A/G and exon 3 C/A polymorphisms are associated with vitiligo susceptibility and influence the TNFB and ICAM1 expression. Moreover, the study also emphasizes influence of TNFB and ICAM1 on the disease progression, onset and gender bias for developing vitiligo. PMID:24312346

    Full Text Available Vitiligo is an ancient disease in which depigmented and hypopigmented macules appear on the skin. It is a disfiguring condition that may lead to severe psychological trauma. Among the many treatment modalities available for use in vitiligo, those using light therapy, and in particular ultraviolet (UV light, are some of the most effective treatments. UV-based therapy includes phototherapy (narrowband UVB, photochemotherapy (psoralens with UVA, and targeted phototherapy (excimer laser and excimer lamp. It is important for any practitioner of UV-based therapy to understand the efficacy of each treatment type, as well as their respective adverse effects. In order to take full advantage of UV-based therapy, location, dosing, and photoadaptation must also be taken into account. This review discusses the various UV-based therapeutic options, adjuvant therapies, optimal dosing guidelines, appropriate patient selection, future treatment options, and recommendations based upon the current evidence and the authors′ experience with vitiligo.

    Full Text Available Stability is a hard-to-define concept in the setting of vitiligo, but is nonetheless extremely crucial to the planning of treatment regimens and also in prognosticating for the patient. There are several ways to judge stability in vitiligo, which include clinical features and, recently, many biochemical, cytological and ultrastructural correlates of the same. These recent advances help in not only in prognosticating individual patients but also in elucidating some of the mechanisms for the pathogenesis of vitiligo, including melanocytorrhagy and oxidative damage to melanocytes.

    Full Text Available Vitiligo is a common pigmentary disorder caused by the destruction of functional melanocytes. Vitamin D is an essential hormone synthesized in the skin and is responsible for skin pigmentation. Low levels of vitamin D have been observed in vitiligo patients and in patients with other autoimmune diseases. Therefore, the relationship between vitamin D and vitiligo needs to be investigated more thoroughly. We reviewed the literature to date regarding the role of vitamin D in skin pigmentation. Our review revealed that vitamin D deficiency has been identified in many conditions, including premature and dysmature birth, pigmented skin, obesity, advanced age, and malabsorption. Vitamin D increases melanogenesis and the tyrosinase content of cultured human melanocytes by its antiapoptotic effect. However, a few growth-inhibitory effects on melanocytes were also reported. Vitamin D regulates calcium and bone metabolism, controls cell proliferation and differentiation, and exerts immunoregulatory activities. Vitamin D exerts its effect via a nuclear hormone receptor for vitamin D. The topical application of vitamin D increased the number of L-3,4-dihydroxyphenylalanine-positive melanocytes. The topical application of vitamin D yields significant results when used in combination with phototherapy and ultraviolet exposure to treat vitiligo in humans. Vitamin D decreases the expression of various cytokines that cause vitiligo. In conclusion, application of vitamin D might help in preventing destruction of melanocytes thus causing vitiligo and other autoimmune disorders. The association between low vitamin D levels and the occurrence of vitiligo and other forms of autoimmunity is to be further evaluated.

    Background. Vitiligo has important clinical and social consequences particularly in the pigmented skin. The present study was conducted to assess the differences in clinicoepidemiological presentation of vitiligo in males and females and to understand the factors associated with spread of vitiligo in them. Methods. This is a cross-sectional analysis of secondary clinical data of 168 vitiligo patients at a tertiary medical centre at Navi Mumbai. We used logistic regression models to estimate the association between gender and clinical characteristics of vitiligo and to evaluate the factors associated with spread of vitiligo. Results. There were no significant differences between the mean ages of males and females; however, males reported a longer duration of disease (6.9 (10.4) years) compared with females (4.9 (7.4) years). Males were significantly more likely to report a family history of vitiligo compared with females (adjusted OR (aOR): 16.87, 95% CI: 2.16 to 131.69). Even though females were more likely to report spread of lesions, the association was not statistically significant (OR: 1.21, 95% CI: 0.62 to 2.36). Discussion. The differences in the clinical presentations between genders highlight the need to understand the different factors (possibly genetic) that may play a part in the pathogenesis of this multifactorial disease in males and females.

    Vitiligo and halo nevus are two common T-cell-mediated skin disorders. Although autoimmunity has been suggested to be involved in both diseases, the relationship between vitiligo and halo nevus is not fully understood. The aim of the current study was to investigate whether vitiligo and halo nevus share the same immunological and oxidative stress response. Infiltrations of T cells, and expressions of chemokine receptors (CXCR3, CCR4, CCR5) and cytotoxic markers (Granzyme B, Perforin) in the lesions of vitiligo and halo nevus were examined by immunohistochemistry. Enzyme-linked immunosorbent assay was performed to analyze the expressions of chemokines in the serum samples and cytotoxic markers secreted by CD8 + T cells which were sorted from the peripheral blood mononuclear cells in healthy donors, vitiligo and halo nevus patients. Tissue levels of chemokine receptors and CXCR3 ligands in healthy controls, vitiligo patients and halo nevus patients were determined by qRT-PCR analysis. The percentages of CXCR3 + CD4 + T and CXCR3 + CD8 + T cells from the peripheral blood samples were examined by flow cytometry. Tissue and serum hydrogen peroxide (H 2 O 2 ) concentrations were measured using H 2 O 2 assay kit. Immunohistochemistry revealed a significant T-cell response, with pronounced dermal infiltrates of CD8 + T cells in vitiligo and halo nevus. The inflammatory cytotoxic markers such as Granzyme B and Perforin were also elevated in vitiligo and halo nevus, suggesting inflammatory responses in situ. By qRT-PCR and ELISA assay, we found significantly increased expressions of the chemokine receptor CXCR3 and its ligands, especially the accumulated CXCL10 in the skin lesions of vitiligo and halo nevus. Moreover, the level of H 2 O 2 , a key player involved in regulation of the immune response was significantly upregulated in the skin lesions of vitiligo and halo nevus. In addition, the increased H 2 O 2 concentration correlated positively with CXCL10 level in skin

    Full Text Available 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%, χ 2 = 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.

    Full Text Available Background: Early lesions of vitiligo can be confused with various other causes of hypopigmentation and depigmentation. Few workers have utilized dermoscopy for the diagnosis of evolving lesions of vitiligo. Aim: To analyze the dermoscopic findings of evolving lesions in diagnosed cases of vitiligo and to correlate them histopathologically. Methods: Dermoscopy of evolving lesions in 30 diagnosed cases of vitiligo was performed using both polarized light and ultraviolet light. Result: On polarized light examination, the pigmentary network was found to be reduced in 12 (40% of 30 patients, absent in 9 (30%, and reversed in 6 (20% patients; 2 patients (6.7% showed perifollicular hyperpigmentation and 1 (3.3% had perilesional hyperpigmentation. A diffuse white glow was demonstrable in 27 (90% of 30 patients on ultraviolet light examination. Melanocytes were either reduced in number or absent in 12 (40% of 30 patients on histopathology. Conclusion: Pigmentary network changes, and perifollicular and perilesional hyperpigmentation on polarized light examination, and a diffuse white glow on ultraviolet light examination were noted in evolving vitiligo lesions. Histopathological examination was comparatively less reliable. Dermoscopy appears to be better than routine histopathology in the diagnosis of evolving lesions of vitiligo and can obviate the need for a skin biopsy.

    Determination of the minimal erythema dose (MED) is important for developing a phototherapy protocol and to diagnosis photosensitivity disorders. But obtaining a precise and reproducible MED is quite difficult because a phototest for erythema is based on subjective assessment. The objective of our study was to compare the gross interpretation of a phototest and the objective measurement using a spectrophotometer for determining the parameters of cutaneous narrow-band UVB (NBUVB) therapy. A total of 14 psoriasis and 10 vitiligo patients who receiving NBUVB phototherapy with skin types III and IV were selected for this study. To perform phototesting, ten sites on the skin of the back were vertically exposed to a series of 10 NBUVB doses among 14 doses between 340 and 1,400 mJ/cm(2). We interpreted the gross findings of erythema and measured the L*a*b* values with using a spectrophotometer at each phototest spot and at the control skin. Also, we evaluate the relationship between the gross presentation and the spectrophotometric analysis by delta E for the assessment of the minimal perceptible erythema (MPE) and MED. For all the subjects, the MEDs were measured in the 490~1,000 mJ/cm(2) range. The average of the colorimetric values for the control skin were L*: 64.8, a*: 7.9 and b*: 19.8. Among them, the L* value and MED value were shown to be inversely correlated, and as the L* value was decreased, the MED was increased. For the MPE, the delta E, which was the color difference of the normal skin and the phototest area, was within the range of 1.5~3.0 in 17 of the 21 patients, and 4 patients were within the range of 1.0~1.5. For the MED, among the 21 patients, the delta E of 17 patients was within the range of 3.0~6.0, and 4 patients were within the range of 6.0~12.0. A spectrophotometer enables UV erythema to be assessed objectively and quantitatively, and this can compensate for the disadvantages of subjective gross interpretation when determining the MED. Delta E is

    Full Text Available Background: Considering safe treatment modalities for children with vitiligo, search for newer therapeutic agents continues. Hence, new immunomodulatory agents such as calcineurinantagonists, frequently referred to as topical immunomodulators (TIMs have recently been introduced as new promising tools to treat acquired hypopigmentary disorders. Tacrolimus is safe in treating children due to lack of skin atrophy and less data are available on effect of topical tacrolimus on vitiligo. Objective: To see the effect of topical tacrolimus on vitiligo in children. Materials and Methods: This prospective study was done in outpatient department of Dermatology and Venereology, Chittagong Medical College Hospital (CMCH, Bangladesh. Clinically diagnosed vitiligo patients of up to 12 years age visiting Skin & VD OPD, CMCH during study period were the study population (total 30. The study was carried out from November 2007 to April 2008. Results: A total of 30 patients, 13 (43.33% males and 17 (56.66% females with focal, segmental or generalized vitiligo were studied. Seventy percent of study subjects were from 7–12 years of age. Topical tacrolimus 0.03% ointment was administered twice daily for 12 weeks to each patient. Repigmentation was complete (>75% in 43.33% cases (13/30, was moderate (50–75% in 33.33% (10/30, mild (<50% in 13.33% (4/30. Clinical adverse effects were noted in 6.67% (2/30 of cases where pruritus was in 3.33% (1/30 and burning in 3.33% (1/30. None of the reactions was severe, all were mild and well-tolerated and most occurred within the first month of initiation of treatment and resolved with continued use of drug and completely cured after the treatment completed. Nobody had to discontinue the therapy for side effects. Conclusion: In conclusion, tacrolimus ointment may be a rapidly efficacious and safe option for the treatment of vitiligo in children. The ease of topical self-administration with minimal side effects makes this novel

    OBJECTIVE To summarize and critically appraise the evidence on the measurement properties of clinician-, patient-, and observer-reported outcomes, measuring any construct of interest in patients with all types of vitiligo. DATA SOURCES Electronic databases including PubMed (1948 to July 2011), OVID EMBASE (1980 to July 2011), and CINAHL (EBSCOhost) (1982 to July 2011) were searched. STUDY SELECTION Two authors independently screened all records for eligibility. For inclusion, the study population had to include patients with vitiligo, for which outcome measures were developed or evaluated on their measurement properties. The initial search retrieved 1249 records, of which 14 articles met the inclusion criteria. DATA EXTRACTION Characteristics of the included instruments, study population, and results of the measurement properties were extracted. The Consensus-Based Standards for the Selection of Health Status Measurement Instruments (COSMIN) 4-point checklist, combined with quality criteria for measurement properties, was used to calculate the overall level of evidence per measurement property of each instrument. Independent extraction and assessment was performed by 2 authors. DATA SYNTHESIS Eleven different measurement instruments were identified. Strong evidence was found for a positive internal consistency of the Dermatology Life Quality Index. For other instruments, the evidence of measurement properties was limited or unknown. CONCLUSIONS Recommendations on the use of specific outcome measures for vitiligo should be formulated with caution because current evidence is insufficient owing to a low number of studies with poor methodological quality and unclear clinical relevance. To recommend outcome measures for vitiligo, further research on measurement properties of clinical relevant outcome measures for vitiligo according to COSMIN quality criteria is needed.

    Vitiligo is an acquired skin disease with pigmentary disorder. Autoimmune destruction of melanocytes is thought to be major factor in the etiology of vitiligo. miRNA-based regulators of gene expression have been reported to play crucial roles in autoimmune disease. Therefore, we attempt to profile the miRNA expressions and predict their potential targets, assessing the biological functions of differentially expressed miRNA. Total RNA was extracted from peripheral blood of vitiligo (experimental group, n = 5) and non-vitiligo (control group, n = 5) age-matched patients. Samples were hybridized to a miRNA array. Box, scatter and principal component analysis plots were performed, followed by unsupervised hierarchical clustering analysis to classify the samples. Quantitative reverse transcription polymerase chain reaction (RT-PCR) was conducted for validation of microarray data. Three different databases, TargetScan, PITA and microRNA.org, were used to predict the potential target genes. Gene ontology (GO) annotation and pathway analysis were performed to assess the potential functions of predicted genes of identified miRNA. A total of 100 (29 upregulated and 71 downregulated) miRNA were filtered by volcano plot analysis. Four miRNA were validated by quantitative RT-PCR as significantly downregulated in the vitiligo group. The functions of predicted target genes associated with differentially expressed miRNA were assessed by GO analysis, showing that the GO term with most significantly enriched target genes was axon guidance, and that the axon guidance pathway was most significantly correlated with these miRNA. In conclusion, we identified four downregulated miRNA in vitiligo and assessed the potential functions of target genes related to these differentially expressed miRNA. © 2017 Japanese Dermatological Association.

    Full Text Available Introduction: Vitiligo in an adult patient has a profound effect on the quality of life (QoL of that particular patient. Although it is known that vitiligo in adult patient affects QoL in their family, very little information is available regarding QoL in a family having children suffering from vitiligo. Materials and Methods: This is a cross-sectional, hospital-based study to ascertain the effect children suffering from vitiligo have on the QoL of their respective families. Study participants were fifty healthy parent/immediate caregivers of fifty corresponding children suffering from vitiligo. The QoL in the family of these vitiliginous children was assessed with the help of Family Dermatology Life Quality Index (FDLQI. Results: There was significantly more impairment of FDLQI among respondents if vitiliginous child was female compared to male. The total FDLQI showed a significant negative correlation with duration of vitiligo in children. Analysis of individual items in FDLQI revealed emotional distress as the most impaired facet of FDLQI and housework as the least affected item. Conclusion: Presence of vitiligo in children affects the QoL of that particular child and his/her family. This impairment of FDLQI is more if the child suffering from vitiligo is female. Treatment of vitiligo in pediatric age group should include psychological counseling and support for the child as well as their parents/caregivers.

    Full Text Available Vitiligo is a common, often heritable, acquired disorder. Although vitiligo does not cause any physical problem but it surely is a psychosocial disaster. Depigmented patches resistant to medical treatment need to be managed surgically. Surgically. Surgical procedures usually performed lead to unsatisfactory results and that too at the cost of scarring of normal donor site. Here we describe our experience with grafting of non-cultured autologous melanocytes, which is not associated with any scarring. We tried this method in 16 lesions in 8 patients of stable vitiligo. Due to its advantages, like no scarring at recipient sites, ability to re-pigment large area with small piece of skin graft, simplicity and feasibility in Indian conditions, this is a good alternative in the treatment of vitiligo.

    Vitiligo is an acquired pigmentry disorder of the skin and mucous membranes which manifests as white macules and patches due to selective loss of melanocytes. Etiological hypotheses of vitiligo include genetic, immunological, neurohormonal, cytotoxic, biochemical, oxidative stress and newer theories of melanocytorrhagy and decreased melanocytes survival. There are several types of vitiligo which are usually diagnosed clinically and by using a Wood's lamp; also vitiligo may be associated with autoimmune diseases, audiological and ophthalmological findings or it can be a part of polyendocrinopathy syndromes. Several interventions are available for the treatment for vitiligo to stop disease progression and/or to attain repigmentation or even depigmentation. In this article, we will present an overall view of current standing of vitiligo research work especially in the etiological factors most notably the genetic components, also, types and associations and various and newer treatment modalities.

    Full Text Available Background: Vitiligo is a common pigmentary disorder. Studies on its pathogenesis extensively investigated melanocytes' abnormalities and few studies searched for keratinocytes' role in disease development. Liver X receptor-α (LXR-α is a member of nuclear hormone receptors that acts as a transcription factor. Its target genes are the main regulators of melanocyte functions. Aim: The aim of this study is to investigate keratinocytes' role in vitiligo pathogenesis through immunohistochemical expression of LXR-α in lesional, perilesional, and distant nonlesional vitiligo skin. Materials and Methods: This case–control study was carried out on 44 participants. These included 24 patients with vitiligo and 20 age- and sex-matched normal individuals as a control group. Biopsies, from cases, were taken from lesional, perilesional, and distant nonlesional areas. Evaluation was done using immunohistochemical technique. Results: Keratinocyte LXR-α expression was upregulated in the lesional and perilesional skin (follicular and interfollicular epidermis compared with control skin (P<0.001 for all. There was significant association between higher histoscore (H-score in lesional epidermis (P<0.001 and in hair follicle (P=0.001 and the presence of angiogenesis. There was significant association between higher H-score in lesional epidermis and suprabasal vacuolization (P=0.02. No significant association was found between H-score or expression percentage and clinical data of selected cases. Conclusion: LXR-α upregulation is associated with keratinocyte damage in vitiligo lesional skin that leads to decreased keratinocyte-derived mediators and growth factors supporting the growth and/or melanization of surrounding melanocytes. Therefore, melanocyte function and survival are affected.

    Continuous cardiac monitoring of healthy and unhealthy patients can help us understand the progression of heart disease and enable early treatment. Optical pulse sensing is an excellent candidate for continuous mobile monitoring of cardiovascular health indicators, but optical pulse signals are susceptible to corruption from a number of noise sources, including motion artifact. Therefore, before higher-level health indicators can be reliably computed, corrupted data must be separated from valid data. This is an especially difficult task in the presence of artifact caused by ambulation (e.g. walking or jogging), which shares significant spectral energy with the true pulsatile signal. In this manuscript, we present a machine-learning-based system for automated estimation of signal quality of optical pulse signals that performs well in the presence of periodic artifact. We hypothesized that signal processing methods that identified individual heart beats (segmenting approaches) would be more error-prone than methods that did not (non-segmenting approaches) when applied to data contaminated by periodic artifact. We further hypothesized that a fusion of segmenting and non-segmenting approaches would outperform either approach alone. Therefore, we developed a novel non-segmenting approach to signal quality estimation that we then utilized in combination with a traditional segmenting approach. Using this system we were able to robustly detect differences in signal quality as labeled by expert human raters (Pearson’s r = 0.9263). We then validated our original hypotheses by demonstrating that our non-segmenting approach outperformed the segmenting approach in the presence of contaminated signal, and that the combined system outperformed either individually. Lastly, as an example, we demonstrated the utility of our signal quality estimation system in evaluating the trustworthiness of heart rate measurements derived from optical pulse signals. (paper)

    Vitiligo is an autoimmune disease of the skin that results in disfiguring white spots. There are no FDA-approved treatments for vitiligo, and most off-label treatments yield unsatisfactory results. Vitiligo patients have increased numbers of autoreactive, melanocyte-specific CD8+ T cells in the skin and blood, which are directly responsible for melanocyte destruction. Here we report that gene expression in lesional skin from vitiligo patients reveals an IFN-γ-specific signature, including the chemokine CXCL10. CXCL10 is elevated in both vitiligo patient skin and serum and CXCR3, its receptor, is expressed on pathogenic T cells. To address the function of CXCL10 in vitiligo, we employed a mouse model of disease that also exhibits an IFN-γ-specific gene signature, expression of CXCL10 in the skin, and upregulation of CXCR3 on antigen-specific T cells. Mice that receive Cxcr3−/− T cells develop minimal depigmentation, as do mice lacking Cxcl10 or treated with CXCL10 neutralizing antibody. CXCL9 promotes autoreactive T cell global recruitment to the skin but not effector function while, in contrast, CXCL10 is required for effector function and localization within the skin. Surprisingly, CXCL10 neutralization in mice with established, widespread depigmentation induces reversal of disease, evidenced by repigmentation. These data identify a critical role for CXCL10 in both the progression and maintenance of vitiligo, and thereby support inhibiting CXCL10 as a targeted treatment strategy. PMID:24523323

Psychosocial is defined as the interrelation of social factors with an individual's thoughts and behavior. The assessment of the psychosocial impact of skin disease on a patient can help direct the dermatologists' treatment goals. To evaluate the psychosocial impact of skin disease, we conducted a review of the literature on three skin conditions with onsets at various stages of life: acne, vitiligo, and psoriasis. Methods: A PubMed search was conducted in March 2015 using the terms “psychosocial” AND “acne”, “psychosocial” AND “vitiligo”, and “psychosocial” AND “psoriasis”. The results were limited to articles published in English in the past 5 years studying patients of all ages. Results and their references were evaluated for relevance according to their discussion of psychosocial qualities in their patients and the validity of psychosocial assessments. The search for acne yielded 51 results, and eleven were found to be relevant; vitiligo yielded 30 results with ten found to be relevant; and psoriasis yielded 70 results with seven found to be relevant. Results: According to the articles evaluated, 19.2% of adolescent patients with acne were affected in their personal and social lives. Social phobia was present in 45% of patients with acne compared to 18% of control subjects. Race and sex played a role in self-consciousness and social perceptions of the disease. Vitiligo

    Full Text Available The treatment of vitiligo is derisory since the pathogenesis of vitiligo is not clear at present. Most conservative treatments are difficult to approach satisfactory therapy. So transplantation is the only way left when the disease becomes insensitive to those conservative treatments. Here we describe an 18-year-old patient who developed vitiligo, which was triggered by graft-versus-host disease after a allogeneic bone marrow transplantation for the treatment of Hodgkin′s lymphoma from his sister. In the following treatment to vitiligo, the patient successfully performed the transplantation of autologous uncultured melanocyte on the premise of poor reaction to other conservative methods. We infer that transplantation can be a treatment of the vitiligo after allogeneic bone marrow transplantation.

    Vitiligo is the most common acquired hypopigmentary disease in the community. Piperine as an herbal extract derived from black pepper has strong impact on the melanocyte proliferation and adverse side effects less than synthetic drugs such as corticosteroids. For the first time, this study was aimed to evaluate the effect of topical piperine combined with narrowband ultraviolet B (NB-UVB) on vitiligo treatment. In this double-blind clinical trial, 63 patients with facial vitiligo were randomly divided into 2 groups: treated with piperine (case) and placebo (control). Also, both groups received NB-UVB phototherapy every other day for 3 months. In the case group, 10 patients have burning sensation on their skin areas (p value = .002). Also, redness of the treated areas was observed in 6 patients (p value = .028). Both side effects were temporary. Regarding repigmentation at time intervals of 1, 2, and 3 months after treatment, its level in the case group was significantly higher than the control group (p value topical piperine has more influence on facial vitiligo than that of NB-UVB alone. It could be concluded that the simultaneous use of NB-UVB and topical piperine has a remarkable effect on treatment of vitiligo. Copyright © 2018 John Wiley & Sons, Ltd.

    Vitiligo is an autoimmune disease in which cutaneous depigmentation occurs. Existing therapies are often inadequate. Prior reports have shown benefit of the Janus kinase (JAK) inhibitors. To evaluate the efficacy of the JAK 1/3 inhibitor tofacitinib in the treatment of vitiligo. This is a retrospective case series of 10 consecutive patients with vitiligo treated with tofacitinib. Severity of disease was assessed by body surface area of depigmentation. Ten consecutive patients were treated with tofacitinib. Five patients achieved some repigmentation at sites of either sunlight exposure or low-dose narrowband ultraviolet B phototherapy. Suction blister sampling revealed that the autoimmune response was inhibited during treatment in both responding and nonresponding lesions, suggesting that light rather than immunosuppression was primarily required for melanocyte regeneration. Limitations include the small size of the study population, retrospective nature of the study, and lack of a control group. Treatment of vitiligo with JAK inhibitors appears to require light exposure. In contrast to treatment with phototherapy alone, repigmentation during treatment with JAK inhibitors may require only low-level light. Maintenance of repigmentation may be achieved with JAK inhibitor monotherapy. These results support a model wherein JAK inhibitors suppress T cell mediators of vitiligo and light exposure is necessary for stimulation of melanocyte regeneration.

    Vitiligo is a disorder of the melanocytes that results in a dynamic spectrum of skin depigmentation. Its etiology is complex and multifactorial, with data supporting several different hypotheses. Given its prominent phenotype, vitiligo has a significant negative impact on quality of life. Coupled with the chronic and incurable nature of the disease, this presents a formidable treatment challenge. Several treatment modalities have been instituted over the years, with varying efficacy. This chapter focuses on the use of ultraviolet light in vitiligo as an established therapeutic option.

    Skin color is determined by the number of melanin granules produced by melanocytes that are transferred to keratinocytes. Melanin synthesis and the distribution of melanosomes to keratinocytes within the epidermal melanin unit (EMU) within the skin of vitiligo patients have been poorly studied. The ultrastructure and distribution of melanosomes in melanocytes and surrounding keratinocytes in perilesional vitiligo and normal skin were investigated using transmission electron microscopy (TEM). Furthermore, we performed a quantitative analysis of melanosome distribution within the EMUs with scatter plot. Melanosome count within keratinocytes increased significantly compared with melanocytes in perilesional stable vitiligo (P vitiligo. Furthermore, melanosome counts within melanocytes and their surrounding keratinocytes in perilesional active vitiligo skin decreased significantly compared with the other groups. In addition, taking the means-standard error of melanosome count within melanocytes and keratinocytes in healthy controls as a normal lower limit, EMUs were graded into 3 stages (I-III). Perilesional active vitiligo presented a significantly different constitution in stages compared to other groups (P vitiligo. Active vitiligo varies in stages and in stage II, EMUs are slightly impaired, but can be resuscitated, providing a golden opportunity with the potential to achieve desired repigmentation with an appropriate therapeutic choice. Adverse milieu may also contribute to the low melanosome count in keratinocytes.

    Vitiligo is a hereditary/acquired progressive pigmentation disorder characterized by discoloration of skin as a result of melanocyte dysfunction. Recent studies have proposed that oxidant/antioxidant status plays an important role in vitiligo pathogenesis because of the toxic effects on melanocytes. In this study, we aimed to investigate possible associations of MnSOD Ala-9Val and GPx1 Pro198Leu polymorphisms with vitiligo with in Turkish population. The study group consists of 57 patients with vitiligo and 69 healthy controls. Genotyping is performed to identify MnSOD Ala-9Val and GPx1 Pro198Leu polymorphisms. The method used for genotyping was based on the PCR amplification and detection of polymorphisms by hybridization probes labeled with fluorescent dyes. Both the genotype and allele frequencies of MnSOD Ala-9Val (p = 0.817 and p = 0.553, respectively) and GPx1 Pro198Leu polymorphisms (p = 0.422 and p = 0.673, respectively) were not significantly different between vitiligo patients and the control group. Although no significant difference was found, this is the first report investigating the possible associations between the MnSOD Ala-9Val and GPx1 Pro198Leu polymorphisms in Turkish population. Further studies with large populations will be able to clarify the association better.

    Full Text Available Vitiligo is a common pigmentary skin condition with a profound impact. Despite a number of therapeutic modalities, few have been demonstrated to result in significant repigmentation within a brief period of time. Reported dietary interventions are sparse. Following exclusion of gluten in the diet, early and extensive repigmentation of facial lesions were noted in a young female adult of Asian ethnicity with acrofacial vitiligo. The majority of the benefits occurred within the first month and stabilized at 4 months. Previous topical and phototherapy had not been found to be effective. The patient was maintained on the previously prescribed dapsone therapy. Dietary elimination can potentially be a disease-modifying intervention for vitiligo and should be considered even in patients without concomitant celiac disease.

    SUMMARY Inducible HSP70 (HSP70i) chaperones peptides from stressed cells, protecting them from apoptosis. Upon extracellular release, HSP70i serves an adjuvant function, enhancing immune responses to bound peptides. We questioned whether HSP70i differentially protects control and vitiligo melanocytes from stress and subsequent immune responses. We compared expression of HSP70i in skin samples, evaluated the viability of primary vitiligo and control melanocytes exposed to bleaching phenols, and measured secreted HSP70i. We determined whether HSP70i traffics to melanosomes to contact immunogenic proteins by cell fractionation, western blotting, electron microscopy and confocal microscopy. Viability of vitiligo and control melanocytes was equally affected under stress. However, vitiligo melanocytes secreted increased amounts of HSP70i in response to MBEH, corroborating with aberrant HSP70i expression in patient skin. Intracellular HSP70i colocalized with melanosomes, and more so in response to MBEH in vitiligo melanocytes. Thus whereas either agent is cytotoxic to melanocytes, MBEH preferentially induces immune responses to melanocytes. PMID:24354861

    Although the precise mechanisms that trigger vitiligo remain elusive, autoimmune responses mediate its progression. The development of therapies has been impeded by a paucity of animal models, since mice lack interfollicular melanocytes, the primary targets in vitiligo. In this issue, Harris et al. describe a mouse model in which interfollicular melanocytes are retained by Kit ligand overexpression and an immune response is initiated by transplanting melanocyte-targeting CD8+ T cells.

    Full Text Available Background: Any residual pigment left in patients of universal vitiligo is managed with topical treatments, cryotherapy, and lasers. Aim: The study aims to assess the efficacy and safety of Q-switched Nd: YAG laser in treating the residual pigmentation in patients with universal vitiligo. Materials and Methods: Fifteen patients of universal vitiligo with residual pigmentation on the face, hands, or feet, resistant to topical treatments, were treated with single or multiple sessions of Q-switched Nd: YAG laser treatment. Topical treatments were continued in between the laser sessions and the depigmentation achieved was monitored by clinical examination and repeat digital photographs. Response to the treatment was labelled as excellent if the residual pigment could be reduced by at least 90% while 50-90% resolution of pigmentation was labelled as a partial response. Adverse effects to the treatment offered were also monitored. Results: Thirteen of the 15 patients enrolled for the study showed an excellent response to the treatment offered. Two other patients showed a poor response with less than 50% resolution of pigmentation. The number of laser sessions needed at a particular site ranged from 1 to 3 and no patient was offered more than three sessions of laser treatment at any site. No significant adverse events were reported by any patient. Conclusions: Residual pigmentation in patients with universal vitiligo that does not respond to topical treatment options alone can be managed quite effectively with Q-switched Nd: YAG laser without any significant adverse effects.

    There is no standardized method for assessing vitiligo. In this article, we review the literature from 1981 to 2011 on different vitiligo assessment methods. We aim to classify the techniques available for vitiligo assessment as subjective, semi-objective or objective; microscopic or macroscopic; and as based on morphometry or colorimetry. Macroscopic morphological measurements include visual assessment, photography in natural or ultraviolet light, photography with computerized image analysis and tristimulus colorimetry or spectrophotometry. Non-invasive micromorphological methods include confocal laser microscopy (CLM). Subjective methods include clinical evaluation by a dermatologist and a vitiligo disease activity score. Semi-objective methods include the Vitiligo Area Scoring Index (VASI) and point-counting methods. Objective methods include software-based image analysis, tristimulus colorimetry, spectrophotometry and CLM. Morphometry is the measurement of the vitiliginous surface area, whereas colorimetry quantitatively analyses skin colour changes caused by erythema or pigment. Most methods involve morphometry, except for the chromameter method, which assesses colorimetry. Some image analysis software programs can assess both morphometry and colorimetry. The details of these programs (Corel Draw, Image Pro Plus, AutoCad and Photoshop) are discussed in the review. Reflectance confocal microscopy provides real-time images and has great potential for the non-invasive assessment of pigmentary lesions. In conclusion, there is no single best method for assessing vitiligo. This review revealed that VASI, the rule of nine and Wood's lamp are likely to be the best techniques available for assessing the degree of pigmentary lesions and measuring the extent and progression of vitiligo in the clinic and in clinical trials. © 2012 The Authors.

    IL-17 is involved in the pathogenesis of several autoimmune diseases, however its role in vitiligo has not been well defined. Emerging human and mouse studies have demonstrated that systemic, tissue, and cellular levels of IL-17 are elevated in vitiligo. Many studies have also shown significant positive correlations between these levels and disease activity, extent, and severity. Treatments that improve vitiligo, such as ultraviolet B phototherapy, also modulate IL-17 levels. This review synthesizes our current understanding of how IL-17 may influence the pathogenesis of autoimmune vitiligo at the molecular level. This has implications for defining new vitiligo biomarkers and treatments. PMID:26804758

    2016-01-01

    Purpose of review Vitiligo and alopecia areata are common, disfiguring skin diseases. Treatment options are limited and include non-targeted approaches such as corticosteroids, topical calcineurin inhibitors, narrow band UVB phototherapy, and other immune-modifying agents. The purpose of this article is to review shared, novel mechanisms between vitiligo and alopecia areata, as well as discuss how they inform the development of future targeted treatments. Recent findings Vitiligo and alopecia areata are both autoimmune diseases, and striking similarities in pathogenesis have been identified at the level of both the innate and adaptive immune system. Increased reactive oxygen species and high cellular stress level have been suggested as the initiating trigger of the innate immune system in both diseases, and genome-wide association studies have implicated risk alleles that influence both innate and adaptive immunity. Most importantly, mechanistic studies in mouse models of vitiligo and alopecia areata have specifically implicated an IFN-γ-driven immune response, including IFN-γ, IFN-γ-induced chemokines, and cytotoxic CD8+ T cells as the main drivers of disease pathogenesis. These recent discoveries may reveal an effective strategy to develop new treatments, and several proof-of-concept clinical studies support this hypothesis. Summary The identification of IFN-γ-driven immune signaling pathways has enabled discoveries of potential new treatments for vitiligo and alopecia areata, and supports initiation of larger clinical trials.

    The aim of this study was to determine serum vitamin B12, folic acid and homocysteine (Hcy) levels as well as MTHFR (C677, A1298C) gene polymorphisms in patients with vitiligo, and to compare the results with healthy controls. Forty patients with vitiligo and 40 age and sex matched healthy subjects were studied. Serum vitamin B12 and folate levels were determined by enzyme-linked immunosorbent assay. Plasma Hcy levels and MTHFR polymorphisms were determined by chemiluminescence and real time PCR methods, respectively. Mean serum vitamin B12 and Hcy levels were not significantly different while folic acid levels were significantly lower in the control group. There was no significant relationship between disease activity and vitamin B12, folic acid and homocystein levels. No significant difference in C677T gene polymorphism was detected. Heterozygote A1298C gene polymorphism in the patient group was statistically higher than the control group. There was no significant relationship between MTHFR gene polymorphisms and vitamin B12, folic acid and homocysteine levels. In conclusion, vitamin B12, folate and Hcy levels are not altered in vitiligo and MTHFR gene mutations (C677T and A1298C) do not seem to create susceptibility for vitiligo. PMID:22846211

    Full Text Available There are various medical and surgical modalities for the treatment of vitiligo. Surgical modalities are used in the patients who fail to respond to medical therapy. We selected thirty patients of stable vitiligo from the department of dermatology for the study. The patients were divided into two groups of 15 patients each. In Group I patients application of 100% TCA was done on the vitiliginous sites and in Group II patients 88% phenol was applied on the affected sites. Comparing the results of repigmentation in both the groups it was seen that marked pigmentation was seen in 66.6% patients in the TCA group and 80% in the Phenol group. Moderate pigmentation was seen in 13.3% patients in both the groups and mild pigmentation was seen in 20% patients in the TCA group and 6.6% in the Phenol group.

    There are many theories explaining vitiligo such as genetic, autoimmune, neural, free radicals, biochemical, intrinsic defect, melanocytorrhagy, and convergent theories. Phenytoin is a widely used anticonvulsant, which is used in cutaneous medicine for treatment of ulcers and epidermolysis bullosa. The aim of this study is to assess the effectiveness of topical phenytoin gel in the treatment of vitiligo patients and explaining the underlying mechanism using immunohistochemistry for evaluation of HMB45, CD4, and CD8. Only 9 patients out of 28 experienced response to phenytoin in the form of dull, white color change and light brown color. Post-phenytoin treatment biopsies showed decreased density of inflammation, increased melanin and increased HMB45 positive cells together with an increased number of CD4 positive lymphocytes and decreased number of CD8 positive lymphocytes. These observations did not reach significant level (P > 0.05). A high percentage of CD4 positive lymphocytes was significantly associated with a long duration of vitiligo (p = 0.03) and segmental vitiligo type (p = 0.02). The current study applied phenytoin as 2% concentrated gel for 3 months, which is a relatively short duration without observed side effects throughout the period. These results indicate that topical phenytoin of low concentrations may have beneficial effects through immunomodulatory activity by affecting CD4 and CD8 counts and subsequently the ratio between them. Further studies are recommended to combine phenytoin with other antivitiligo agents as local corticosteroids or phototherapy to clarify if it could potentiate their effects.

    Several treatment modalities had been used for the treatment of vitiligo, but the optimal treatment has not yet been identified. To study the efficacy of microneedling with 5-flurouracil vs its efficacy with tacrolimus in the treatment of vitiligo. Twenty-five patients with vitiligo were subjected to microneedling of 2 patches of vitiligo with dermapen, then application of 5-fluorouracil to 1 patch and tacrolimus on the other patch. This procedure was repeated every 2 weeks for every patient for maximum 6 months (12 sessions). The patients were followed up for 3 months after the last session. The overall repigmentation was significantly higher in 5-fluorouracil-treated patches compared with tacrolimus. Excellent improvement occurred in 48% of 5- flurouracil-treated patches while only in 16% of tacrolimus-treated patches. In the acral parts, 40% of the patches treated with 5-fluorouracil achieved excellent improvement (repigmentation >75%), while no patch in the acral parts achieved excellent improvement with tacrolimus. However, there was significant difference between the 2 drugs,regarding inflammation, ulceration, and hyperpigmentation which occurred with 5-fluorouracil. Microneedling combined with 5-fluorouracil or tacrolimus is safe and effective treatment of vitiligo. However, 5-fluorouracil achieved a greater percentage of repigmentation than tacrolimus particularly in the acral parts. © 2018 Wiley Periodicals, Inc.

    Full Text Available A 26-year-old Chinese male consulted with the team regarding his alopecia areata and vitiligo for which previous treatment was ineffective. The patient, a homosexual man, denied having a history of drug abuse and of blood transfusion. No member of his family had vitiligo or alopecia. Laboratory studies revealed that the serum for anti-human immunodeficiency virus (HIV antibody was positive. The patient′s CD4 lymphocyte count and CD4/CD8 ratio were both strikingly low (20 cells/mL and 0.04, but no other complaints or opportunistic infections were reported. One month after antiretroviral therapy, the patient′s alopecia areata dramatically improved, but no evident improvement in his vitiligo was found. This case is a very rare case of alopecia areata and vitiligo associated with HIV infection that might be attributed to the generation and maintenance of self-reactive CD8+ T-cells due to chronic immune activation with progressive immune exhaustion in HIV infection.

    Depigmentation therapy can be an option in adults with extensive and refractory vitiligo. Remaining pigmented patches can be removed using depigmentation creams (monobenzyl ether of hydroquinone 20%), laser therapy or cryotherapy. In contrast to cream treatment, laser therapy and cryotherapy are fast and targeted methods, capable of destroying melanocytes selectively on one specific area. Up till now, controlled trials comparing laser and cryotherapy as depigmenting treatment in vitiligo are lacking. We performed a retrospective comparative study in 22 generalized vitiligo patients. Thirty-one pigmented test regions were exposed to cryotherapy and 20 to 755 nm laser therapy. The mean surface area per test region was 3.55 cm2 and number of treatments per test region was limited to one single session in 84.3% and varied up to four sessions (2.0%). Overall no significant difference in the capacity to induce depigmentations was observed between cryotherapy (46.7%) and laser therapy (42.9%) after one treatment. The percentage of induced depigmentation was significantly different according to the body location (P = 0.005) with best results on the trunk, followed by the arms, face, neck and less on the hands. Variables that positively influenced depigmentation results were a younger age of vitiligo onset (P = 0.012), skin type V (P cryotherapy and concerned mainly hyperpigmentation in the face. To our knowledge, this is the first study comparing head-to-head depigmentation strategies intra- and inter-individually. We could demonstrate that in general laser and cryotherapy are equally effective in inducing depigmentations in generalized vitiligo patients. Retreatment of the same area may be required in case of initial failure. © 2014 European Academy of Dermatology and Venereology.

    Vitiligo is characterized by the progressive disappearance of pigment cells from skin and hair follicle. Several in vitro and in vivo studies show evidence of an altered redox status, suggesting that loss of cellular redox equilibrium might be the pathogenic mechanism in vitiligo. However, despite the numerous data supporting a pathogenic role of oxidative stress, there is still no consensus explanation underlying the oxidative stress-driven disappear of melanocytes from the epidermis. In this study, in vitro characterization of melanocytes cultures from non-lesional vitiligo skin revealed at the cellular level aberrant function of signal transduction pathways common with neurodegenerative diseases including modification of lipid metabolism, hyperactivation of mitogen-activated protein kinase (MAPK) and cAMP response element-binding protein (CREB), constitutive p53-dependent stress signal transduction cascades, and enhanced sensibility to pro-apoptotic stimuli. Notably, these long-term effects of subcytotoxic oxidative stress are also biomarkers of pre-senescent cellular phenotype. Consistent with this, vitiligo cells showed a significant increase in p16 that did not correlate with the chronological age of the donor. Moreover, vitiligo melanocytes produced many biologically active proteins among the senescence-associated secretory phenotype (SAPS), such as interleukin-6 (IL-6), matrix metallo proteinase-3 (MMP3), cyclooxygenase-2 (Cox-2), insulin-like growth factor-binding protein-3 and 7 (IGFBP3, IGFBP7). Together, these data argue for a complicated pathophysiologic puzzle underlying melanocytes degeneration resembling, from the biological point of view, neurodegenerative diseases. Our results suggest new possible targets for intervention that in combination with current therapies could correct melanocytes intrinsic defects. PMID:23555779

    Vitiligo is a complex disorder in which autoimmune destruction of melanocytes results in white patches of skin and overlying hair. Over the past several years, extensive genetic studies have outlined a biological framework of vitiligo pathobiology that underscores its relationship to other autoimmune diseases. This biological framework offers insight into both vitiligo pathogenesis and perhaps avenues towards more effective approaches to treatment and even disease prevention. PMID:23668538

    Full Text Available Vitiligo is a disorder that causes the destruction of melanocytes. It has three important factors underlying this destruction. The depigmented skin has many aberrant functions such as a muted response to contact allergens, a phenomenon also seen in mice that depigment. The white skin of those with vitiligo does not form non-melanoma skin cancers although the white skin of albinos, which has a similar color as vitiligo, is highly susceptible to skin cancer.

    Treatment of vitiligo with narrowband ultraviolet B light (NBUVB) is an important component of the current standard of care. However, there are no consistent guidelines regarding the dosing and administration of NBUVB in vitiligo, reflected by varied treatment practices around the world. To create phototherapy recommendations to facilitate clinical management and identify areas requiring future research. The Vitiligo Working Group (VWG) Phototherapy Committee addressed 19 questions regarding the administration of phototherapy over 3 conference calls. Members of the Photomedicine Society and a group of phototherapy experts were surveyed regarding their phototherapy practices. Based on comparison and analysis of survey results, expert opinion, and discussion held during conference calls, expert recommendations for the administration of NBUVB phototherapy in vitiligo were created. There were several areas that required further research before final recommendations could be made. In addition, no standardized methodology was used during literature review and to assess the strength of evidence during the development of these recommendations. This set of expert recommendations by the VWG is based on the prescribing practices of phototherapy experts from around the world to create a unified, broadly applicable set of recommendations on the use of NBUVB in vitiligo.

    The Vitiligo Global Issues Consensus Conference (VGICC), through an international e-Delphi consensus, concluded that 'repigmentation' and 'maintenance of gained repigmentation' are essential core outcome measures in future vitiligo trials. This VGICC position paper addresses these core topics in two sections and includes an atlas depicting vitiligo repigmentation patterns and color match. The first section delineates mechanisms and characteristics of vitiligo repigmentation, and the second section summarizes the outcomes of international meeting discussions and two e-surveys on vitiligo repigmentation, which had been carried out over 3 yr. Treatment is defined as successful if repigmentation exceeds 80% and at least 80% of the gained repigmentation is maintained for over 6 months. No agreement was found on the best outcome measure for assessing target or global repigmentation, therefore highlighting the limitations of e-surveys in addressing clinical measurements. Until there is a clear consensus, existing tools should be selected according to the specific needs of each study. A workshop will be conducted to address the remaining issues so as to achieve a consensus. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2013-01-01

    Full Text Available Background: Oral minipulse (OMP therapy with methylprednisolone is presently one of the most common oral treatments used for progressive vitiligo in children. The treatment is usually given for a period of 6 months during which majority of patients are reported to go into remission. However, there are no follow-up studies to comment upon what happens to the disease after OMP therapy is withdrawn. Aim of the study: To document the incidence of relapse over a period of 1 year after OMP therapy is stopped in children with vitiligo. Materials and Methods: The study was conducted in 180 patients of childhood vitiligo (<15 years of age who had been on OMP therapy with oral methylprednisolone for at least 6 months and who had achieved a complete remission of their disease during the treatment period. The enrolled patients were followed up for a period of 1 year and examined clinically for any sign of reactivation of their disease over either the old lesions or at any new area of the body. Results: Forty-two patients were lost and could not complete the follow-up period of 1 year. Out of the 138 patients available at the end of 1 year, relapse was observed in 48 patients (34.8%. Rest of 90 patients remained in remission over the follow-up period of 1 year. Relapse was more common in patients below 10 years of age (47.4% as compared with older children (25.9%. Conclusion: Relapse after using methylprednisolone OMP therapy in children with vitiligo is quite common especially in younger age groups. Studies are needed to see whether these relapses could be avoided by giving the treatment for a period longer than 6 months.

    Vitiligo is a repugnant and odious dermatological malady of the time. It has an detrimental impact on the pigmentation of the human skin as a result of the destruction of cutaneous melanocytes. It affects 1%-2% of the population worldwide. Different therapeutic regimens have been deployed to treat vitiligo, but none of them could stand alone to be stated as a perfect cure. Recently, a change has been observed through novel experimental-designed optimization leading to the development of an anti-vitiligo ointment containing Psoralea corylifolia (PC) seed powder. The aim of this study was to explore the clinical outcomes of ointment containing powdered seeds of PC. Guided by the protocol Response Surface Methodology, 13 formulations of concentration variance of permeation enhancers were prepared. The formulation fulfilling the required criteria (pH; temperature stability tests at 8°C±0.1°C, 25°C±0.1°C and 40°C±0.1°C; and the physical properties such as color, bleeding and rheology) was selected for clinical trials. Fourier transform infrared spectroscopy studies of seed powder of PC and selected formulation of the seed powder were performed. After obtaining informed consents and with prior approval of university and hospital ethical review boards, 20 patients (age range 25-65 years) were included in the present study. Formulations were applied on the affected body parts of patients, and some affected portion of the same patient was taken as control (self-control study design). The pigmentation of white spots of vitiligo was photographically evaluated before, during and after 12 weeks of treatment. Analysis of the measured values was performed using GraphPad Prism version 5 statistical software. A paired sample t -test was performed to observe variation between repigmented patches and white patches of self-control. Hydrophilic ointment (10% w/w) prepared with seed powder of PC was fabricated. The ointment was found effective for small circular white lesions

    Oxidative stress has a critical role in the pathogenesis of vitiligo. However, the specific molecular mechanism involved in oxidative stress-induced melanocyte death is not well characterized. Given the powerful role of microRNAs (miRNAs) in the regulation of cell survival as well as the fact that the generation of miRNAs can be affected by oxidative stress, we hypothesized that miRNAs may participate in vitiligo pathogenesis by modulating the expression of vital genes in melanocytes. In the present study, we initially found that miR-25 was increased in both serum and lesion samples from vitiligo patients, and its serum level was correlated with the activity of vitiligo. Moreover, restoration of miR-25 promoted the H2O2-induced melanocyte destruction and led to the dysfunction of melanocytes. Further experiments proved that MITF, a master regulator in melanocyte survival and function, accounted for the miR-25-caused damaging impact on melanocytes. Notably, other than the direct role on melanocytes, we observed that miR-25 inhibited the production and secretion of SCF and bFGF from keratinocytes, thus impairing their paracrine protective effect on the survival of melanocytes under oxidative stress. At last, we verified that oxidative stress could induce the overexpression of miR-25 in both melanocytes and keratinocytes possibly by demethylating the promoter region of miR-25. Taken together, our study demonstrates that oxidative stress-induced overexpression of miR-25 in vitiligo has a crucial role in promoting the degeneration of melanocytes by not only suppressing MITF in melanocytes but also impairing the paracrine protective effect of keratinocytes. Therefore, it is worthy to investigate the possibility of miR-25 as a potential drug target for anti-oxidative therapy in vitiligo. PMID:26315342

    Halo congenital melanocytic nevus (CMN) associated with vitiligo is rare, especially with regard to CMN excision. Only two reports of excision of halo CMN following repigmentation of vitiligo are found in the literature. We present a case of a girl with halo CMN and periorbital vitiligo. The halo CMN was excised and followed by spontaneous improvement of vitiligo. The result suggests excision of the inciting lesion may be a promising way to control vitiligo. © 2015 Wiley Periodicals, Inc.

    Full Text Available Background: Ensuring stability of the disease process is essential for undertaking surgical intervention in vitiligo. However, there is no consensus regarding the minimum duration of stability or the relative importance of disease and lesional stability in selecting patients for vitiligo grafting. Aim: This multicentric study aims to assess the relative importance of lesional and disease stability on selecting patients for vitiligo grafting. Materials and Methods: One hundred seventy patients were recruited into the study and divided into two groups: Group A with lesional stability of >1 year but overall disease stability of only 6-11 months and Group B with overall disease stability of >1 year. Patients underwent either tissue or cellular vitiligo grafting on the selected lesions and the repigmentation achieved was scored from 0 (no repigmentation to 6 (100% repigmentation. Repigmentation achieved on different sites of the body was compared between the two groups. Adverse effects at both the donor and the recipient sites were also compared. Results: Of the 170 patients who were enrolled, 82 patients were placed in Group A and 88 patients in Group B. Average repigmentation achieved (on scale of 0 to 6 was 3.8 and 4.04 in Group A and Group B, respectively. In Group A, ≥90% repigmentation was achieved in 36.6% (30/82 patients, while 37.5% (33/88 achieved similar results in Group B. Additionally, 47.6% (39/82 and 53.4% (47/88 of cases achieved partial repigmentation in Group A and Group B, respectively. Perigraft halo was the commonest adverse effect observed in both groups. Statistical analysis revealed no significant differences between the two groups with respect to the repigmentation achieved or adverse effects observed. Repigmentation achieved was the best on the face and neck area, while acral areas responded the least. Conclusions: Lesional stability seems to be as relevant as the overall disease stability in selecting patients for

    Vitiligo is a pigmentary disorder of skin affecting at least 1% of the world population of all races in both sexes. Its importance is mainly due to subsequent social and psychological problems rather than clinical complications. Various treatment choices are available for vitiligo; however, laser-based courses have shown to give more acceptable results. The aim of this trial was to evaluate the efficacy of Er:YAG laser as a supplementary medicine to topical 5FU and clobetasol in vitiligo patients. Two comparable vitiligo patches from 38 eligible patients were randomized to receive topical 5FU and clobetasol in control group and additional Er:YAG laser in intervention group. Major outcomes of interest were the size of patch and pigmentation score at randomization and 2 and 4 months after therapy. Final sample included 18 (47%) male patients and age of 35.66±8.04. The performance Er:YAG group was superior in all sites. Reduction in the size of patches was greater in Er:YAG group (p-value=.004). Also, this group showed a higher pigmentation scores in the trial period than control group (p-value<.001). Greater reduction in the size and increase in pigmentation score was seen in Er:YAG group especially for short periods after therapy and repeating laser sessions may help improving final outcomes. Er:AYG could help in reducing complications of long-term topical treatments, achieving faster response, and improving patient adherence. © 2017 Wiley Periodicals, Inc.

    Hashimoto thyroiditis (HT) is the most common pediatric autoimmune endocrine disorder. It results in autoimmune-mediated thyroid gland destruction and is an organ-specific, typical autoimmune disease. The presence of antithyroid antibodies and the typical pattern on ultrasonography indicate the diagnosis. It is also frequently seen together with other autoimmune disorders including type 1 insulin-dependent diabetes, celiac disease, alopecia and vitiligo. Autoimmune hepatitis (AIH) is a chronic type of liver injury with an immune etiology that can frequently cause end-stage liver disease if left untreated. Autoimmune hepatitis patients may present with hepatitis, and the laboratory tests in the absence of other etiology usually reveal a positive immune serology together with elevated immunoglobulins and abnormal liver histology. It is interesting that HT and AIH are rarely seen together although both have an autoimmune etiology. 14-year-old male who was being followed-up for vitiligo presented with symptoms of a swelling at the neck and fatigue. He was diagnosed with HT after the tests and the liver enzymes were found to be high. The patient was also diagnosed with AIH after tests revealed that the liver enzyme elevation had continued for longer than six months. The thyroid functions and liver enzymes returned to normal and the symptoms decreased after sodium L-thyroxine replacement together with steroid and azathioprine treatment. We present this case as we believe it is the first pediatric patient diagnosed with HT, AIH and vitiligo.

    Patients with acute vitiligo have low epidermal catalase expression/activities and accumulate 10 -3 M H 2 O 2 . One consequence of this severe oxidative stress is an altered calcium homeostasis in epidermal keratinocytes and melanocytes. Here, we show decreased epidermal calmodulin expression in acute vitiligo. Since 10 -3 M H 2 O 2 oxidises methionine and tryptophan residues in proteins, we examined calcium binding to calmodulin in the presence and absence of H 2 O 2 utilising 45 calcium. The results showed that all four calcium atoms exchanged per molecule of calmodulin. Since oxidised calmodulin looses its ability to activate calcium ATPase, enzyme activities were followed in full skin biopsies from lesional skin of patients with acute vitiligo (n = 6) and healthy controls (n = 6). The results yielded a 4-fold decrease of ATPase activities in the patients. Computer simulation of native and oxidised calmodulin confirmed the loss of all four calcium ions from their specific EF-hand domains. Taken together H 2 O 2 -mediated oxidation affects calcium binding in calmodulin leading to perturbed calcium homeostasis and perturbed L-phenylalanine-uptake in the epidermis of acute vitiligo

    Cerebral infarction is a rare neurological situation in young adults, usually caused by genetic factors. We report here a case of multiple cerebral infarctions with prothrombin G20210A mutation, hypogonadotropic hypogonadism, and generalized vitiligo as a first case report. A 17-year-old female adolescent was admitted to our clinic due to a change in mental status. The patient's neurological examination revealed loss of consciousness and the presence of tetraparesia. Generalized vitiligo was also detected. Magnetic resonance imaging (MRI) and diffusion-weighted investigations (DWIs) showed acute ischemic stroke in the bilateral cerebellum, pons and left occipital regions. Heterozygote prothrombin G20210A mutation was found upon genetic examination. She had never had a menstrual cycle. Laboratory data revealed that the level of luteinizing hormone (LH) was 0.5 mIU/mL (1.1-11.6) and follicle-stimulating hormone (FSH) was 1.7 mIU/mL (2.8-11.3). Therefore, she was diagnosed with hypogonadotropic hypogonadism. The causes of ischemic stroke are heterozygote prothrombin G20210A mutation, generalized vitiligo, and hypogonadotropic hypogonadism. After treatment, the patient's neurological deficit partially improved and she was discharged. In order to identify the etiology of ischemic stroke, we suggest physicians take into account heterozygote prothrombin G20210A mutation and endocrine abnormalities, especially hypogonadotropic hypogonadism and generalized vitiligo.

    Full Text Available Background: Generalized vitiligo is a disease with unpredictable bursts of activity, goal of treatment during the active phase being to stabilize the lesions. This emphasizes the need for a prospective marker for monitoring disease activity to help decide the duration of therapy. Aims and Objectives: In the present study, we examined whether reactive oxygen species (ROS generated in erythrocytes can be translated into a marker of activity in vitiligo. Materials and Methods: Level of intracellular ROS was measured flow cytometrically in erythrocytes from venous blood of 21 patients with generalized vitiligo and 21 healthy volunteers using the probe dichlorodihydrofluorescein diacetate. Results: The levels of ROS differed significantly between patients and healthy controls, as well as between active versus stable disease groups. In the active disease group, ROS levels were significantly lower in those being treated with systemic steroids than those that were not. ROS levels poorly correlated with disease duration or body surface area involved. Conclusion: A long-term study based on these findings can be conducted to further validate the potential role of ROS in monitoring disease activity vitiligo.

    Vitiligo is an acquired dermatological disease frequently associated with autoimmune thyroid disorders. Several theories have been proposed so far to unravel the complex vitiligo pathogenesis. Currently, the autocytotoxic and the autoimmune theories are the most accredited hypothesis, since they are sustained by several important clinical and experimental evidences. A growing body of evidences shows that autoimmunity and oxidative stress strictly interact to finally determine melanocyte loss. In this scenario, associated thyroid autoimmunity might play an active and important role in triggering and maintaining the depigmentation process of vitiligo. PMID:25838868

    Full Text Available Follicular unit extraction (FUE is a surgical procedure, which can be used to transplant follicular units into vitiliginous areas. Such follicular unit transplant has been recently used to repigment stable vitiligo patches. FUE was done for a 12-year-old female with a stable vitiligo patch with leukotrichia on the eyebrow. Repigmentation was noted in 6 weeks and complete pigmentation seen at 12 weeks. Leukotrichia resolved over a period of 6 months. No recurrence was noted at the end of 6 months follow-up with excellent colour match. This case is presented to highlight the simplicity, safety and effectiveness of FUE in stable vitiligo patches with leukotrichia.

    Vitiligo is a common autoimmune disease that progressively destroys melanocytes in the skin, resulting in the appearance of patchy depigmentation. This disfiguring condition frequently affects the face and other visible areas of the body, which can be psychologically devastating. The onset of vitiligo often occurs in younger individuals and progresses for life, resulting in a heavy burden of disease and decreased quality of life. Presentation patterns of vitiligo vary, and recognition of these patterns provides both diagnostic and prognostic clues. Recent insights into disease pathogenesis offer a better understanding of the natural history of the disease, its associations, and potential for future treatments. The first article in this continuing medical education series outlines typical and atypical presentations of vitiligo, how they reflect disease activity, prognosis, and response to treatment. Finally, we discuss disease associations, risk factors, and our current understanding of disease pathogenesis. Copyright © 2016 American Academy of Dermatology, Inc. All rights reserved.

    We evaluated whether TAP1-rs1135216 (p.637D>G) and PSMB9-rs17587 (p.60R>H) were significantly associated with the risk and severity of vitiligo among Saudi patients. One hundred seventy-two subjects were genotyped for the TAP1-rs1135216 and PSMB9-rs17587 variants using endonuclease digestions of amplified genomic DNA. The TAP1-rs1135216 and PSMB9-rs17587 mutant alleles were strongly associated with vitiligo, with odds ratios showing five fold and two fold risks (P Vitiligo vulgaris was the most common type of disease, associated with the DG (55%) and GG (46%) genotypes for rs1135216 and with the RH genotype (59%) for rs17587. The heterozygous 637DG and 60RH genotypes were each linked with active phenotypes in 64% of cases. In conclusion, the TAP1-rs1135216 and PSMB9-rs17587 variants are significantly associated with vitiligo, and even one copy of these mutant alleles can influence the risk among Saudis. Vitiligo vulgaris is associated with genotypes containing the mutant G and H alleles. PMID:25548428

    Acquired skin hypopigmentation has many etiologies, including autoimmune melanocyte destruction, skin aging, inflammation, and chemical exposure. Distinguishing lesions from normally pigmented skin is clinically important to precisely assess disease severity. However, no gold standard assessment method has been reported. We aimed to investigate whether spectrophotometers are useful for assessing vitiligo and rhododendrol (4-(4-hydroxyphenol)-2-butanol) (Rhododenol ® )-induced leukoderma disease severity by quantifying skin color. Mexameter ® MX18 and CM-700d spectrophotometer were used for assessing vitiligo/leukoderma by measuring melanin index, L*a*b* color space, and ΔE*ab value, which represents the color difference between two subjects and is calculated by the values of L*a*b*. MX18 and CM-700d can quantitatively distinguish vitiligo/leukoderma from normally pigmented skin based on melanin index. CM-700d consistently quantified the color of vitiligo/leukoderma lesions and surrounding normally pigmented skin in L*a*b* color spaces and ΔE*ab. ΔE*ab is well correlated with melanin index and clinical appearance. ΔE*ab has been frequently used in aesthetic dentistry; however, current study is the first to use it in the measurement of skin color. ΔE*ab seems to be a useful parameter to evaluate the color contrast between vitiligo/leukoderma and surrounding normally pigmented skin and can be used to evaluate disease severity and patient's quality of life. © 2017 John Wiley & Sons A/S.

    Vitiligo is a multifactorial acquired depigmenting disorder. Recent insights into the molecular mechanisms driving the gradual destruction of melanocytes in vitiligo will likely lead to the discovery of novel therapies, which need to be evaluated in animal models that closely recapitulate the pathogenesis of human vitiligo. In humans, vitiligo is characterized by a spontaneous loss of functional melanocytes from the epidermis, but most animal models of vitiligo are either inducible or genetically programmed. Here, we report that acquired depigmentation in water buffalo recapitulates molecular, histological, immunohistochemical, and ultrastructural changes observed in human vitiligo and hence could be used as a model to study vitiligo pathogenesis and facilitate the discovery and evaluation of therapeutic interventions for vitiligo. © 2016 John Wiley & Sons A/S.

    Full Text Available BACKGROUND Vitiligo, the commonest of all pigmentary disorders, is an idiopathic, acquired cutaneous achromia, characterised by circumscribed, chalky white macules. It may also involve the pigment epithelium of the eyes, the inner ear and the leptomeninges. Although, vitiligo can begin at any age, it develops before the age of 20 years in 50% of the patients and before the age of 10 years in 25% of patients. MATERIALS AND METHODS The study was conducted for a period of one year with 6 months active intervention. A group of 60 consecutive children attending the outpatient Department of Dermatology were included in this study. The same patients were acting as controls. RESULTS Grade 4 response was seen in 12 cases (60% who were on mometasone (VV-20%, focal-30%, segmental-10%, in 10 cases (50% on tacrolimus (VV-20%, focal-30% and in 4 cases (20% on bFGF (focal. Lesions on the face and neck showed grade 4 response in 16 cases (mometasone-8, tacrolimus-6 and bFGF-2, extremities in 6 cases. On the whole grade, 4 response was observed more with mometasone (60% followed by tacrolimus (50%. Grade 3 response was observed with bFGF (30%. CONCLUSION Topical mometasone was very effective among the 3 drugs used in childhood vitiligo showing grade 4 repigmentation in all types of vitiligo except mucosal vitiligo. Tacrolimus proved almost as effective as mometasone to restore skin colour in lesions of vitiligo in children. Because it does not produce atrophy or other adverse effects, tacrolimus may be very useful for younger patients, and for sensitive areas of the skin such as eyelids, it should be considered in other skin disorders currently treated with topical steroids for prolonged periods. Topical basic fibroblast growth factor though less effective than mometasone and tacrolimus, but can be tried as initial therapy in resistant cases such as segmental vitiligo as initial therapy of small vitiligo patches when physicians may not like to initiate high risk

    Full Text Available A 30 year old female presented with generalized stable vitiligo involving large areas of the body. Since large areas were to be treated it was decided to do meshed split skin graft. A phototoxic blister over recipient site was induced by applying 8 MOP solution followed by exposure to UVA. The split skin graft was harvested from donor area by Padgett dermatome which was meshed by an ampligreffe to increase the size of the graft by 4 times. Significant pigmentation of the depigmented skin was seen after 5 months. This procedure helps to cover large recipient areas, when pigmented donor skin is limited with minimal risk of scarring. Phototoxic blister enables easy separation of epidermis thus saving time required for dermabrasion from recipient site.

    Full Text Available Abstract Background Vitiligo is a hypopigmentation disorder affecting 1 to 4% of the world population. Fifty percent of cases appear before the age of 20 years old, and the disfigurement results in psychiatric morbidity in 16 to 35% of those affected. Methods Our objective was to complete a comprehensive, systematic review of the published scientific literature to identify natural health products (NHP such as vitamins, herbs and other supplements that may have efficacy in the treatment of vitiligo. We searched eight databases including MEDLINE and EMBASE for vitiligo, leucoderma, and various NHP terms. Prospective controlled clinical human trials were identified and assessed for quality. Results Fifteen clinical trials were identified, and organized into four categories based on the NHP used for treatment. 1 L-phenylalanine monotherapy was assessed in one trial, and as an adjuvant to phototherapy in three trials. All reported beneficial effects. 2 Three clinical trials utilized different traditional Chinese medicine products. Although each traditional Chinese medicine trial reported benefit in the active groups, the quality of the trials was poor. 3 Six trials investigated the use of plants in the treatment of vitiligo, four using plants as photosensitizing agents. The studies provide weak evidence that photosensitizing plants can be effective in conjunction with phototherapy, and moderate evidence that Ginkgo biloba monotherapy can be useful for vitiligo. 4 Two clinical trials investigated the use of vitamins in the therapy of vitiligo. One tested oral cobalamin with folic acid, and found no significant improvement over control. Another trial combined vitamin E with phototherapy and reported significantly better repigmentation over phototherapy only. It was not possible to pool the data from any studies for meta-analytic purposes due to the wide difference in outcome measures and poor quality ofreporting. Conclusion Reports investigating the

    Visual clinical methods of skin color evaluation for diagnostic purposes are so far mostly subjective and thus inaccurate. We present a modified method of melanin amount measurement based on diffuse reflectance spectroscopy (DRS). This method is non-invasive and objective, and allows easy quantification and comparison of melanin levels. Skin pigmentation was measured by DRS method in 0-18 year old patients at the Department of Pediatric Dermatovenerology, School of Medicine Comenius University Bratislava. Patients were treated for their vitiligo by Balneo PUVA treatment twice weekly. Each patient had measured his remittance spectra from the treated vitiliginous skin before the treatment was started, after 10 irradiations of Balneo PUVA and at the end of the treatment after 25 irradiations of Balneo PUVA. In our study as a reference skin for spectroscopic assessment of melanin in vivo was used the averaged remittance spectra (measured on the inner arm) from the sample of 10 albino patients. The remittance spectra obtained from the vitiligo patients were ratioed against the newly described remittance reference albino skin. We exploited the linear behavior of the spectral curve in the 620-720 nm interval (significant for melanin absorption) and used the slope of the regression line to compute the quantification index α. By clinical examination before the Balneo PUVA therapy, after the 10th dose of Balneo PUVA therapy as well as at the end of the complete course of Balneo PUVA therapy (after 25 irradiations) we recorded a marked increase of pigmentation in all treated patients for their vitiligo. In each patient the values of melanin quantification angle α were calculated. Statistically we found a significant difference between the melanin quantification angle α in vitiliginous skin before, during the 10th dose of treatment and after the treatment. Similar significant difference was also observed between treated and non-involved skin. We could confirm a clear

    Full Text Available Background: Different surgical techniques in the form of tissue or cellular grafting procedures are used alone or in combination with narrowband UVB (NBUVB to treat stable vitiligo resistant to medical treatment. Aim: To evaluate the cosmetic results obtained with ultrathin split-thickness skin grafts followed by NBUVB therapy in resistant, stable vitiligo. Methods: Forty patients of stable vitiligo were treated with ultrathin split-thickness grafting and the patients were then put on NBUVB therapy. The results obtained were analyzed by the extent of repigmentation achieved as well as the final cosmetic outcome at the recipient as well as donor sites. Results: The first evidence of repigmentation was seen in the second week after starting NBUVB. On objective assessment, more than 90% repigmentation was seen in 83% of patients and the overall cosmetic results at the recipient site were graded as good to excellent in 90% patients at the end of NBUVB treatment. Perigraft halo of depigmentation was seen in six patients (15% on the recipient site. Hypertrophic scarring was observed in two patients at the donor site. Conclusions: Ultrathin split-thickness skin grafting, when combined with NBUVB therapy, leads to better cosmetic outcome with faster onset of repigmentation in resistant stable vitiligo.

    Full Text Available BACKGROUND: Vitiligo is a depigmenting disorder resulting from loss of functional melanocytes in the skin. NPY plays an important role in induction of immune response by acting on a variety of immune cells. NPY synthesis and release is governed by IL1B. Moreover, genetic variability in IL1B is reported to be associated with elevated NPY levels. OBJECTIVES: Aim of the present study was to explore NPY promoter -399T/C (rs16147 and exon2 +1128T/C (rs16139 polymorphisms as well as IL1B promoter -511C/T (rs16944 polymorphism and to correlate IL1B transcript levels with vitiligo. METHODS: PCR-RFLP method was used to genotype NPY -399T/C SNP in 454 patients and 1226 controls; +1128T/C SNP in 575 patients and 1279 controls and IL1B -511C/T SNP in 448 patients and 785 controls from Gujarat. IL1B transcript levels in blood were also assessed in 105 controls and 95 patients using real-time PCR. RESULTS: Genotype and allele frequencies for NPY -399T/C, +1128T/C and IL1B -511C/T SNPs differed significantly (p<0.0001, p<0.0001; p = 0.0161, p = 0.0035 and p<0.0001, p<0.0001 between patients and controls. 'TC' haplotype containing minor alleles of NPY polymorphisms was significantly higher in patients and increased the risk of vitiligo by 2.3 fold (p<0.0001. Transcript levels of IL1B were significantly higher, in patients compared to controls (p = 0.0029, in patients with active than stable vitiligo (p = 0.015, also in female patients than male patients (p = 0.026. Genotype-phenotype correlation showed moderate association of IL1B -511C/T polymorphism with higher IL1B transcript levels. Trend analysis revealed significant difference between patients and controls for IL1B transcript levels with respect to different genotypes. CONCLUSION: Our results suggest that NPY -399T/C, +1128T/C and IL1B -511C/T polymorphisms are associated with vitiligo and IL1B -511C/T SNP influences its transcript levels leading to increased risk for vitiligo in

    Full Text Available Background Vitiligo is an acquired disease in which the loss of functional melanocytes results in depigmented macules and patches. Over the years, wide arrays of markers for melanocytes have been described, including human melanoma black 45 (HMB-45. Narrow-band ultraviolet B (NB-UVB therapy is one of the therapeutic modalities for vitiligo. Objectives We sought to detect HMB-45 staining after 30 sessions of NB-UVB therapy in vitiligo and perivitiliginous skin. Patients and Methods All the participants were planned to have 30 sessions of NB-UVB therapy with 724 lamps (FS, 72 T, 12-HO Daavlin MED at 311 nm wavelengths. The patients underwent skin sampling from lesional and perilesional area before and after 30 sessions of treatment. The skin biopsies were sent to the laboratory for light microscopy and immunohistochemical study. The evaluation of HMB-45 was based on the quantitative method, measuring the number of positive stained cells. Clinical response was defined as repigmentation in three categories: more than 75%; between 40% and 75%; and less than 40%. The data were analyzed using SPSS (version 17. Results Twenty-nine patients completed the study. The Wilcoxon test showed a meaningful relation between HMB-45 staining before and after NB-UVB treatment in perilesional skin. We did not find a meaningful relation between HMB-45 staining before and after treatment regarding the mean age, gender, mean duration of disease, and initial lesional area (P = 0.55, P = 0.41, P = 0.55, and P = 0.87, respectively. After 30 sessions of NB-UVB therapy, repigmentation was less than 40% in 8 (27.6%, 40 - 75% in 7 (24.1%, and more than 75% in 6 patients. Conclusions The HMB-45 stain strength significantly changed after treatment in perilesional skin.

    Narrowband - ultraviolet B (NB-UVB) is an emerging, effective, and safe therapy for vitiligo, but the treatment course often requires a long duration of time which may carry a potential risk for various side effects and patients' noncompliance. To explore the effect of platelet-rich plasma (PRP) injection on the outcome of short-term NB-UVB therapy for the patients with stable vitiligo. The study included 60 stable vitiligo patients with overall symmetrical lesions. For each patient, the left side of the body was treated with NB-UVB alone (control side) while the right side was treated with NB-UVB therapy in addition to intradermal injection of PRP, every 2 weeks for 4 months. There was statistically highly significant improvement in the repigmentation in the combination group(PRP plus NB-UVB) compared with NB-UVB group. Intradermal PRP injection in combination with NB-UVB could be considered as a simple, safe, tolerable, and cheap technique for treatment of vitiligo. It shortens the duration of NB-UVB therapy and is expected to increase patient compliance. Longer follow-up is needed. © 2015 Wiley Periodicals, Inc.

    The aim of this study is to understand how many anchor sites are necessary to obtain maximum posterior correction of idiopathic scoliotic curve and if the alloy of instrumentation, stainless steel or titanium, may have a role in the percent of scoliosis correction. We reviewed 143 consecutive patients, affected by AIS (Lenke 1-2), who underwent a posterior spinal fusion with pedicle screw-only instrumentation between 2002 and 2005. According to the implant density and alloy used we divided the cohort in four groups. All 143 patients were reviewed at an average follow-up of 7, 2 years, the overall final main thoracic curve correction averaged 61.4%, whereas the implant density within the major curve averaged 71%. A significant correlation was observed between final% MT correction and preoperative MT flexibility and implant density. When stainless steel instrumentation is used non-segmental pedicle screw constructs seem to be equally effective as segmental instrumentations in obtaining satisfactory results in patients with main thoracic AIS. When the implant alloy used is titanium one, an implant density of ≥60% should be guaranteed to achieve similar results.

    Autoimmunity has been implicated in the destruction of melanocytes from vitiligo skin. Major histocompatibility complex (MHC) class-II linked genes proteasome subunit beta 8 (PSMB8) and transporter associated with antigen processing 1 (TAP1), involved in antigen processing and presentation have been reported to be associated with several autoimmune diseases including vitiligo. To explore PSMB8 rs2071464 and TAP1 rs1135216 single nucleotide polymorphisms and to estimate the expression of PSMB8 and TAP1 in patients with vitiligo and unaffected controls from Gujarat. PSMB8 rs2071464 polymorphism was genotyped using polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) and TAP1 rs1135216 polymorphism was genotyped by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) in 378 patients with vitiligo and 509 controls. Transcript levels of PSMB8 and TAP1 were measured in the PBMCs of 91 patients and 96 controls by using qPCR. Protein levels of PSMB8 were also determined by Western blot analysis. The frequency of 'TT' genotype of PSMB8 polymorphism was significantly lowered in patients with generalized and active vitiligo (p = 0.019 and p = 0.005) as compared to controls suggesting its association with the activity of the disease. However, TAP1 polymorphism was not associated with vitiligo susceptibility. A significant decrease in expression of PSMB8 at both transcript level (p = 0.002) as well as protein level (p = 0.0460) was observed in vitiligo patients as compared to controls. No significant difference was observed between patients and controls for TAP1 transcripts (p = 0.553). Interestingly, individuals with the susceptible CC genotype of PSMB8 polymorphism showed significantly reduced PSMB8 transcript level as compared to that of CT and TT genotypes (p = 0.009 and p = 0.003 respectively). PSMB8 rs2071464 was associated with generalized and active vitiligo from Gujarat whereas TAP1 rs1135216 showed no association. The

    The parents of an 18-year-old woman had noticed white hair while combing their daughter's hair 12 years ago. They found tiny white spots on her scalp, but she was asymptomatic. The spots have since progressed. Examination of the affected skin on the scalp was marked by the presence of a chalky/ivory white macule, 8 to 10 cm in diameter, conforming to that of segmental (zosteriformis) vitiligo (Figure 1). The lesions were located on the temporoparietal region of the scalp. The hair over the macules was white (leukotrichia) and dry, coarse, and brittle. The patient's nails were thin and dull. Her thyroid profile revealed the following: triiodothyronine, 1.12 nmol/L (0.95-2.5 nmol/L); thyroxine, 69.21 nmol/L (60.0-120.0 nmol/L); and thyroid-stimulating hormone, 6.26 microIU/mL (0.25-5.00 microIU/mL), indicative of primary hypothyroidism. Liver and renal function tests were within normal limits. A lipid profile revealed the following: total lipids, 503.8 mg% (400-700 mg %); triglycerides, 123.0 mg % (160 mg %); cholesterol, 212.0 mg % (150-250 mg %); high-density lipoprotein, 43.1 mg % (30-63 mg %); and low-density lipoprotein, 144.3 mg % (50 mg %). Electrocardiographic findings were normal. History of tiredness, constipation, depression, sensitivity to cold, weight gain, muscle weakness, cramps, and increased menstrual flow supported the diagnosis. The patient was administered 100 microg of thyroxine once a day along with methoxsalen, the dose of which was calculated at 0.6 mg/kg to 0.7 mg/kg body weight per day given on alternate days, followed 2 hours later by exposure to UV-A (1 J/cm2) irradiation (psoralen-UV-A [PUVA]), supplemented by 1 mg of beta-methasone, 150 mg of levamisole on 2 consecutive days per week, and an antioxidant. During the course of 7 weeks, the macules (13 exposures) had become erythematous, with an appearance of perifollicular/ marginal pigmentation. Repeat examination showed a thyroid profile of total triiodothyronine (T3), 127.3 microg

    Full Text Available An 18-year old girl with segmental vitiligo involving the left side of the trunk and left upper limb with segmental morphea involving the right side of trunk and right upper limb without any deeper involvement is illustrated. There was no history of preceding drug intake, vaccination, trauma, radiation therapy, infection, or hormonal therapy. Family history of stable vitiligo in her brother and a history of type II diabetes mellitus in the father were elicited. Screening for autoimmune diseases and antithyroid antibody was negative. An autoimmune link explaining the co-occurrence has been proposed. Cutaneous mosiacism could explain the presence of both the pathologies in a segmental distribution.

    Vitiligo is an autoimmune disease in which depigmented skin results from the destruction of melanocytes, with epidemiological association with other autoimmune diseases. In previous linkage and genome-wide association studies (GWAS1 and GWAS2), we identified 27 vitiligo susceptibility loci in patients of European ancestry. We carried out a third GWAS (GWAS3) in European-ancestry subjects, with augmented GWAS1 and GWAS2 controls, genome-wide imputation, and meta-analysis of all three GWAS, followed by an independent replication. The combined analyses, with 4,680 cases and 39,586 controls, identified 23 new significantly associated loci and 7 suggestive loci. Most encode immune and apoptotic regulators, with some also associated with other autoimmune diseases, as well as several melanocyte regulators. Bioinformatic analyses indicate a predominance of causal regulatory variation, some of which corresponds to expression quantitative trait loci (eQTLs) at these loci. Together, the identified genes provide a framework for the genetic architecture and pathobiology of vitiligo, highlight relationships with other autoimmune diseases and melanoma, and offer potential targets for treatment.

    Full Text Available BACKGROUND: Minipunch grafting has been successfully used for the treatment of stable vitiligo since several years. Post-operative immobilization at certain sites such as lips, areola & infralabial folds and joints is not easy to achieve. Putting stay sutures on the lips and areolae is difficult. Grafting over the joints may require hospitalization to ensure proper immobilization, and may discourage some patients. AIM: To study the efficacy of a tissue glue for immobilization of donor grafts at the above sites during minipunch grafting. METHODS: Ten cases with stable vitiligo over the lips, areolae, below the lower lip, and over different joints had tissue glue applied to the edges between the donor grafts and the recipient wells, after the grafting. RESULTS: The grafts adhered firmly within a minute and there was no need for a cumbersome dressing. Over the lips, the patients could resume talking and drinking fluids immediately. CONCLUSION: The glue was very helpful for immobilizing the grafts at these difficult sites.

    Vitiligo is a common depigmentation disorder characterized by a loss of functional melanocytes and melanin from epidermis, in which the autoantigens and subsequent autoimmunity caused by oxidative stress play significant roles according to hypotheses. Various factors lead to reactive oxygen species (ROS) overproduction in the melanocytes of vitiligo: the exogenous and endogenous stimuli that cause ROS production, low levels of enzymatic and non-enzymatic antioxidants, disturbed antioxidant pathways and polymorphisms of ROS-associated genes. These factors synergistically contribute to the accumulation of ROS in melanocytes, finally leading to melanocyte damage and the production of autoantigens through the following ways: apoptosis, accumulation of misfolded peptides and cytokines induced by endoplasmic reticulum stress as well as the sustained unfolded protein response, and an 'eat me' signal for phagocytic cells triggered by calreticulin. Subsequently, autoantigens presentation and dendritic cells maturation occurred mediated by the release of antigen-containing exosomes, adenosine triphosphate and melanosomal autophagy. With the involvement of inducible heat shock protein 70, cellular immunity targeting autoantigens takes the essential place in the destruction of melanocytes, which eventually results in vitiligo. Several treatments, such as narrow band ultraviolet, quercetin and α-melanophore-stimulating hormone, are reported to be able to lower ROS thereby achieving repigmentation in vitiligo. In therapies targeting autoimmunity, restore of regulatory T cells is absorbing attention, in which narrow band ultraviolet also plays a role. Copyright © 2015 Elsevier Ireland Ltd.

    Strassner, James P; Harris, John E

    2016-01-01

    Vitiligo is an autoimmune disease of the skin that leads to life-altering depigmentation and remains difficult to treat. However, clinical observations and translational studies over 30-40 years have led to the development of an insightful working model of disease pathogenesis: Genetic risk spanning both immune and melanocyte functions is pushed over a threshold by known and suspected environmental factors to initiate autoimmune T cell-mediated killing of melanocytes. While under cellular stress, melanocytes appear to signal innate immunity to activate T cells. Once the autoimmune T cell response is established, the IFN-γ-STAT1-CXCL10 signaling axis becomes the primary inflammatory pathway driving both progression and maintenance of vitiligo. This pathway is a tempting target for both existing and developing pharmaceuticals, but further detailing how melanocytes signal their own demise may also lead to new therapeutic targets. Research in vitiligo may be the future key to understand the pathogenesis of organ-specific autoimmunity, as vitiligo is common, reversible, progresses over the life of the individual, has been relatively well-defined, and is quite easy to study using translational and clinical approaches. What is revealed in these studies can lead to innovative treatments and also help elucidate the principles that underlie similar organ-specific autoimmune diseases, especially in cases where the target organ is less accessible.

    Full Text Available Vitiligo, an acquired depigmentation disorder, manifests as white macules on the skin and can cause significant psychological stress and stigmatization. Recent advances have shed light on key components that drive disease onset and progression as well as therapeutic approaches. Vitiligo can be triggered by stress to the melanin pigment-producing cells of the skin, the melanocytes. The triggers, which range from sunburn to mechanical trauma and chemical exposures, ultimately cause an autoimmune response that targets melanocytes, driving progressive skin depigmentation. The most significant progress in our understanding of disease etiology has been made on three fronts: (1 identifying cellular responses to stress, including antioxidant pathways and the unfolded protein response (UPR, as key players in disease onset, (2 characterizing immune responses that target melanocytes and drive disease progression, and (3 identifying major susceptibility genes. The current model for vitiligo pathogenesis postulates that oxidative stress causes cellular disruptions, including interruption of protein maturation in the endoplasmic reticulum (ER, leading to the activation of the UPR and expression of UPR-regulated chemokines such as interleukin 6 (IL-6 and IL-8. These chemokines recruit immune components to the skin, causing melanocytes to be targeted for destruction. Oxidative stress can further increase melanocyte targeting by promoting antigen presentation. Two key components of the autoimmune response that promote disease progression are the interferon (IFN-γ/CXCL10 axis and IL-17-mediated responses. Several genome-wide association studies support a role for these pathways, with the antioxidant gene NRF2, UPR gene XBP1, and numerous immune-related genes including class I and class II major histocompatibility genes associated with a risk for developing vitiligo. Novel approaches to promote repigmentation in vitiligo are being investigated and may yield

    The pathophysiology of vitiligo is complex although recent research has discovered several markers which are linked to vitiligo and associated with disease activity. Besides providing insights into the driving mechanisms of vitiligo, these findings could reveal potential biomarkers. Activity markers can be used to monitor disease activity in clinical trials and may also be useful in daily practice. The aim of this systematic review was to document which factors have been associated with vitiligo activity in skin and blood. A second goal was to determine how well these factors are validated in terms of sensitivity and specificity as biomarkers to determine vitiligo activity. Both in skin (n=43) as in blood (n=66) an adequate number of studies fulfilled the predefined inclusion criteria. These studies used diverse methods and investigated a broad range of plausible biomarkers. Unfortunately, sensitivity and specificity analyses were scarce. In skin, simple histopathology with or without supplemental CD4 and CD8 stainings can still be considered as the gold standard, although more recently chemokine (C-X-C motif) ligand (CXCL) 9 and NLRP1 have demonstrated a good and possibly even better association with progressive disease. Regarding circulating biomarkers, cytokines (IL-1β, IL-17, IFN-γ, TGF-β), autoantibodies, oxidative stress markers, immune cells (Tregs), soluble CDs (sCD25, sCD27) and chemokines (CXCL9, CXCL10) are still competing. However, the two latter may be preferable as both chemokines and soluble CDs are easy to measure and the available studies display promising results. A large multicenter study could make more definitive statements regarding their sensitivity and specificity. Copyright © 2017 Elsevier B.V. All rights reserved.

    Vitiligo is a visible condition that is more noticeable in darker-skinned people. Beliefs about illness have been linked to psychosocial adjustment. There is some evidence that such beliefs may be influenced by cultural factors. Surprisingly little is known about beliefs in relation to vitiligo. The study sought to explore in depth the ways in which British Asian women manage and adjust psychosocially to vitiligo, and the potential role of ethnicity and culture in this process. In-depth semistructured interviews were conducted with seven British women of South Asian decent and analysed using the qualitative method of template analysis. Participants described feeling visibly different and all had experienced stigmatization to some extent. Avoidance and concealment were commonplace. Experiences of stigmatization were often perceived to be associated with cultural values related to appearance, status, and myths linked to the cause of the condition. The findings of this study present a unique in-depth analysis of British South Asians living with vitiligo and suggest there is a need for further research to explore cultural associations of disfigurement and of adjustment to chronic skin conditions. Furthermore, they suggest that in addition to individual therapeutic interventions there may be a need for community interventions aimed at dispelling myths and raising awareness of sources of support and treatment. © 2010 The Authors.

    Full Text Available Response of vitiligo patients to five different regimes was evaluated taking only those patients who had either static or progressively increasing lesions. Selection of the regimen depended upon the clinical characteristics of the disease. Each regime was tried for at least 4 months and if a patient didnot improve with one regime, he was shifted to another regime. A patient was considered to have improved, if the lesions started regimenting or the previously progressive lesions stopped increasing further. Regime I consisted of 150 mg levamisol orally on two consecutive days per week, given to 13 cases, it resulted in improvement in 7 (53.80/o. Regime II consisted of levamisole in the same dose combined with once a day topical massage with 0.1% fluocinolone acetonide acetate cream; it led to improvement in 27 (81.8% of the 33 cases. Regime III consisted of 3 mg betamethasone orally on alternate days combined with levamisole and topical fluocinolone; given to 32 cases, it was successful in 28 (87.50/o. A combination of 2 mg betamethasone orally alternating with 20 mg 8-methoxypsoralen and sun exposure (regime IV caused improvement in 17 (85% of the 20 cases. An oral mini pulse consisting of 5 mg betamethasone orally twice a week combined with 50 mg cyclophosphimide daily orally (regime V was successful in 20 (90.9% of the 22 cases, the remaining two cases showed unprovement when the dose ofbetamethasonc .was increased from 5 mg to 7.5 mg twice a week. Thus ultimately each one of the 91 patients responded to one or the other regime. The side effects were minimal and insignificant.The degree of improvement at the time of analysis was 100% in 23.3% cases, 50-100% in 44.2′Yo cases and less than 50% in 32.5%, after 4-14 months of treatment. It is felt that the results may be better after a longer follow-up although all patients are not expected to get complete repigmentation.

    The host innate immune system serves as the first line of defense against viral infections. Germline-encoded pattern recognition receptors detect molecular patterns associated with pathogens and activate innate immune responses. Of particular relevance to viral infections are those pattern recognition receptors that activate type I interferon responses, which establish an antiviral state. The order Mononegavirales is composed of viruses that possess single-stranded, non-segmented negative-sense (NNS) RNA genomes and are important human pathogens that consistently antagonize signaling related to type I interferon responses. NNS viruses have limited encoding capacity compared to many DNA viruses, and as a likely consequence, most open reading frames encode multifunctional viral proteins that interact with host factors in order to evade host cell defenses while promoting viral replication. In this review, we will discuss the molecular mechanisms of innate immune evasion by select NNS viruses. A greater understanding of these interactions will be critical in facilitating the development of effective therapeutics and viral countermeasures.

    2014-04-01

    Full Text Available “Wolf’s isotopic response” describes the occurrence of a new skin disorder at the site of another, unrelated and already healed skin disease. In most cases of isotopic response, the initial dermatosis is herpes zoster, herpes simplex, varicella, thrombophlebitis, scrofuloderma and striae distense. The most frequent second dermatoses are granulomatous reactions, particularly granuloma annulare, and lichenoid diseases. Various etiological reasons including viral, immunologic, neural and vascular have been put forth. We report here a case in which the second disease was herpes zoster that appeared over the same dermatomes of pre-existing segmental vitiligo. The occurrence of vitiligo as first and herpes zoster as second disease in the “Wolf’s isotopic response” has not, to the best of our knowledge, been reported previously.

    Full Text Available An elderly man, a known case of generalized vitiligo of long duration, presented to us with an ulcerated exophytic growth arising from the vitiliginous skin. The histopathological study confirmed the clinical suspicion of squamous cell carcinoma. Cutaneous neoplasia arising from the vitiliginous skin is a rare situation. Lack of melanin leaves the skin vulnerable to ultraviolet radiation damage, which may predispose to cutaneous neoplasia. Therefore, the importance of photoprotection has been stressed upon through this illustration.

    Subsequent vitiligo after hematopoietic stem cell transplantation (HSCT) has been described sporadically in case series. To investigate the incidence and risk factors of subsequent vitiligo after HSCT. A nationwide, population-based cohort study was performed using the Korean National Health Insurance Claims Database from 2009 to 2013. All HSCT recipients who had undergone HSCT between 2010 and 2011 and not treatment for vitiligo in 2009 (to exclude preexisting active vitiligo) were included in the HSCT recipient group, and an age- and sex-matched control group without HSCT was also established. A total of 2747 HSCT recipients and 8241 controls were enrolled. Newly acquired vitiligo occurred in 1.06% of HSCT recipients between 2010 and 2013, and there was a significant increase (OR 3.130, 95% CI 1.859-5.271) in cases of vitiligo in HSCT recipients compared with controls (0.34%). Allogeneic HSCT (OR 5.593, 95% CI 1.628-19.213) and bone marrow-sourced stem cells (as compared with peripheral blood-sourced stem cells; OR 2.492, 95% CI 1.114-5.576) were independently associated with the development of vitiligo after HSCT. Medical record review was not available. Vitiligo developed at a significantly increased rate after HSCT compared with controls. Allogeneic HSCT and bone marrow-sourced stem cells were independent risk factors. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

    Full Text Available Background: Various surgical procedures for correcting stable vitiligo exist but these have their own limitations. Autologous, non-cultured, non-trypsinized, melanocyte plus keratinocyte grafting is a new and simple method of vitiligo surgery. Objective: The study aimed to evaluate efficacy of a new grafting technique in vitiligo patches. Methods: Eighteen vitiligo patches underwent this procedure. The upper layer of epidermis was removed by superficial dermabrasion using a dermabrader micromotor until the epidermis appeared wet and shiny. Then, antibiotic ointment was applied and dermabrasion was continued up to the whitish area of the upper dermis. The paste-like material (ointment with entangled epidermal particles was collected and spread over the dermabraded recipient site. Results: Pigmentation usually started at 4-6 weeks. Complete uniform pigmentation took 16-20 weeks. Conclusion: For smaller vitiligo patches this method gives cosmetically acceptable results. It is easy to perform and does not require specific laboratory setup.

    Full Text Available Non-small cell lung cancer is still diagnosed at late stage due to the lack of early symptoms and methods of diagnostic prevention. In the past ten years several targeted therapies have been introduced or explored. Tyrosine kinase inhibitors and immunotherapy are currently considered the most effective and safe therapies in comparison to the non-specific cytotoxic agents. Regarding tyrosine kinase inhibitors the adverse effects have been fully explored, however; on the other hand for immunotherapy there are still several issues to be clarified. We report a rare case of a patient with lung cancer adenocarcinoma who developed vitiligo throughout his body after nivolumab administration.

    Background Vitiligo is a depigmenting disorder resulting from loss of functional melanocytes in the skin. NPY plays an important role in induction of immune response by acting on a variety of immune cells. NPY synthesis and release is governed by IL1B. Moreover, genetic variability in IL1B is reported to be associated with elevated NPY levels. Objectives Aim of the present study was to explore NPY promoter −399T/C (rs16147) and exon2 +1128T/C (rs16139) polymorphisms as well as IL1B promoter −511C/T (rs16944) polymorphism and to correlate IL1B transcript levels with vitiligo. Methods PCR-RFLP method was used to genotype NPY -399T/C SNP in 454 patients and 1226 controls; +1128T/C SNP in 575 patients and 1279 controls and IL1B −511C/T SNP in 448 patients and 785 controls from Gujarat. IL1B transcript levels in blood were also assessed in 105 controls and 95 patients using real-time PCR. Results Genotype and allele frequencies for NPY −399T/C, +1128T/C and IL1B −511C/T SNPs differed significantly (pvitiligo by 2.3 fold (pvitiligo (p = 0.015), also in female patients than male patients (p = 0.026). Genotype-phenotype correlation showed moderate association of IL1B -511C/T polymorphism with higher IL1B transcript levels. Trend analysis revealed significant difference between patients and controls for IL1B transcript levels with respect to different genotypes. Conclusion Our results suggest that NPY −399T/C, +1128T/C and IL1B −511C/T polymorphisms are associated with vitiligo and IL1B −511C/T SNP influences its transcript levels leading to increased risk for vitiligo in Gujarat population. Up-regulation of IL1B transcript in patients advocates its possible role in autoimmune pathogenesis of vitiligo. PMID:25221996

    Fluorescence signals depend on the intensity of the exciting light, the absorption properties of the constituent molecules, and the efficiency with which the absorbed photons are converted to fluorescence emission. The optical features and appearance of vitiligo have been explained primarily on the basis of reduced epidermal pigmentation, which results in abnormal white patches on the skin. The objective of this study is to explore the fluorescence properties of vitiligo and its adjacent normal skin using fluorescence excitation-emission matrix (EEM) spectroscopy. Thirty five (35) volunteers with vitiligo were acquired using a double-grating spectrofluorometer with excitation and emission wavelengths of 260-450 nm and 300-700 nm respectively. As expected, the most pronounced difference between the spectra obtained from vitiligo lesions compared to normally pigmented skin was that the overall fluorescence was much higher in vitiligo; these differences increased at shorter wavelengths, thus matching the characteristic spectral absorption of epidermal melanin. When comparing the fluorescence spectra from vitiligo to normal skin we detected three distinct spectral bands centered at 280nm, 310nm, and 335nm. The 280nm band may possibly be related to inflammation, whereas the 335 nm band may arise from collagen or keratin cross links. The source of the 310 nm band is uncertain; it is interesting to note its proximity to the 311 nm UV lamps used for vitiligo phototherapy. These differences are accounted for not only by changes in epidermal pigment content, but also by other optically active cutaneous biomolecules.

    Full Text Available Rarely cases have been reported regarding depigmented lesions of the oral cavity. On reviewing the literature, only few cases of gingival vitiligo or similar lesions have been reported till date. These lesions pose a cosmetic challenge. We present here a case of vitiligo affecting gingiva. Vitiligo has been defined as an acquired, slowly progressive loss of cutaneous pigment which occurs as irregular, sharply defined patches which may or may not be surrounded by macroscopic hyperpigmentation. Differential diagnosis, detailed clinical history, histopathology, immunohistochemistry, and pathogenesis of this condition are discussed.

    Genetic risk for autoimmunity in HLA genes is most often attributed to structural specificity resulting in presentation of self-antigens. Autoimmune vitiligo is strongly associated with the MHC class II region. Here, we fine-map vitiligo MHC class II genetic risk to three SNPs only 47 bp apart, located within a predicted super-enhancer in an intergenic region between HLA-DRB1 and HLA-DQA1, localized by a genome-wide association study of 2,853 Caucasian vitiligo patients. The super-enhancer corresponds to an expression quantitative trait locus for expression of HLA-DR and HLA-DQ RNA; we observed elevated surface expression of HLA-DR (P = 0.008) and HLA-DQ (P = 0.02) on monocytes from healthy subjects homozygous for the high-risk SNP haplotype. Unexpectedly, pathogen-stimulated peripheral blood mononuclear cells from subjects homozygous for the high-risk super-enhancer haplotype exhibited greater increase in production of IFN-γ and IL-1β than cells from subjects homozygous for the low-risk haplotype. Specifically, production of IFN-γ on stimulation of dectin-1, mannose, and Toll-like receptors with Candida albicans and Staphylococcus epidermidis was 2.5- and 2.9-fold higher in high-risk subjects than in low-risk subjects, respectively (P = 0.007 and P = 0.01). Similarly, production of IL-1β was fivefold higher in high-risk subjects than in low-risk subjects (P = 0.02). Increased production of immunostimulatory cytokines in subjects carrying the high-risk haplotype may act as an "adjuvant" during the presentation of autoantigens, tying together genetic variation in the MHC with the development of autoimmunity. This study demonstrates that for risk of autoimmune vitiligo, expression level of HLA class II molecules is as or more important than antigen specificity.

    Vitiligo is the most common cutaneous depigmentation disorder worldwide, yet little is known about specific risk factors for disease development. Using data from the Nurses' Health Study, a prospective cohort study of 51,337 white women, we examined the associations between (i) pigmentary traits and (ii) reactions to sun exposure and risk of incident vitiligo. Nurses' Health Study participants responded to a question about clinician-diagnosed vitiligo and year of diagnosis (2001 or before, 2002-2005, 2006-2009, 2010-2011, or 2012+). We used Cox proportional hazards regression models to estimate the multivariate-adjusted hazard ratios and 95% confidence intervals of incident vitiligo associated with exposures variables, adjusting for potential confounders. We documented 271 cases of incident vitiligo over 835,594 person-years. Vitiligo risk was higher in women who had at least one mole larger than 3 mm in diameter on their left arms (hazard ratio = 1.37, 95% confidence interval = 1.02-1.83). Additionally, vitiligo risk was higher among women with better tanning ability (hazard ratio = 2.59, 95% confidence interval = 1.21-5.54) and in women who experienced at least one blistering sunburn (hazard ratio = 2.17, 95% confidence interval = 1.15-4.10). In this study, upper extremity moles, a higher ability to achieve a tan, and history of a blistering sunburn were associated with a higher risk of developing vitiligo in a population of white women.

    Full Text Available The combination of at least three autoimmune diseases in the same patient has defined as multiple autoimmune syndrome (MAS. Abnormalities of T cell-mediated immunity and humoral immunity have been described previously in the literature. Aims of work were to investigate the 22 years old patient with lupus erythematosus for three years and autoimune thyroiditis for one year, regardind other possible autoimmune conditions and to establish a treatment to control the diseases. The clinical exam revealed some circular hairless patches on the beard appeared about three months ago and white depigmented disseminated areas started one month ago and the laboratory investigations were performed. The modified laboratory findings were total IgE 530 UI/mL, Anti-SSA (anti-RO antibodies> 200 IU/mL, SSB negative, Antinuclear antibodies (ANA positive and fine speckled, Lupus anticoagulant testing positive, Anti-thyroid peroxidase antibodies 951 UI/ml, TSH 4,7 µUI/mL. The diagnosis of multiple autoimmune syndrome(MAS type 3 including Lupus erythematosus, autoimune Thyroiditis, Alopecia Areata and Vitiligo was established. Endocrine autoimmunities are associated with autoantibodies that react to specific antigens, whereas patients with collagen diseases synthesize immunoglobulins that recognize nonorgan-specific cellular targets, such as nucleoproteins and nucleic acids. Cellular autoimmunity is important in the pathogenesis MAS. The existence of one autoimmune disorder helps lead to the discovery of other autoimmune conditions.

    Full Text Available Porphyria cutanea tarda (PCT is a cutaneous porphyria that presents later in life with cutaneous findings in sun-exposed sites. We report a complex case of PCT in a 67-year-old woman with an unusual constellation of cutaneous findings: scleroderma, acquired ichthyosis, and nonscarring alopecia. Possible triggers for her PCT include tamoxifen treatment for breast cancer and carrier status of the hemochromatosis gene. High-dose chloroquine was used to successfully achieve clinical remission and normalize her uroporphyrins. While on chloroquine she developed extensive classic vitiligo. It is not clear if this is another feature of her complex and unusual PCT, or a consequence of her antimalarial therapy.

    Significant gaps remain regarding the pathomechanisms underlying the autoimmune response in vitiligo (VL), where the loss of self-tolerance leads to the targeted killing of melanocytes. Specifically, there is incomplete information regarding alterations in the systemic environment that are relevant to the disease state. We undertook a genome-wide profiling approach to examine gene expression in the peripheral blood of VL patients and healthy controls in the context of our previously published VL-skin gene expression profile. We used several in silico bioinformatics-based analyses to provide new insights into disease mechanisms and suggest novel targets for future therapy. Unsupervised clustering methods of the VL-blood dataset demonstrate a "disease-state"-specific set of co-expressed genes. Ontology enrichment analysis of 99 differentially expressed genes (DEGs) uncovers a down-regulated immune/inflammatory response, B-Cell antigen receptor (BCR) pathways, apoptosis and catabolic processes in VL-blood. There is evidence for both type I and II interferon (IFN) playing a role in VL pathogenesis. We used interactome analysis to identify several key blood associated transcriptional factors (TFs) from within (STAT1, STAT6 and NF-kB), as well as "hidden" (CREB1, MYC, IRF4, IRF1, and TP53) from the dataset that potentially affect disease pathogenesis. The TFs overlap with our reported lesional-skin transcriptional circuitry, underscoring their potential importance to the disease. We also identify a shared VL-blood and -skin transcriptional "hot spot" that maps to chromosome 6, and includes three VL-blood dysregulated genes (PSMB8, PSMB9 and TAP1) described as potential VL-associated genetic susceptibility loci. Finally, we provide bioinformatics-based support for prioritizing dysregulated genes in VL-blood or skin as potential therapeutic targets. We examined the VL-blood transcriptome in context with our (previously published) VL-skin transcriptional profile to address

    Vitiligo is an autoimmune disease of the skin that results in the destruction of melanocytes and the clinical appearance of white spots. Disease pathogenesis depends on IFN-γ and IFN-γ-induced chemokines to promote T-cell recruitment to the epidermis where melanocytes reside. The skin is a complex organ, with a variety of resident cell types. We sought to better define the microenvironment and distinct cellular contributions during autoimmunity in vitiligo, and we found that the epidermis is a chemokine-high niche in both a mouse model and human vitiligo. Analysis of chemokine expression in mouse skin showed that CXCL9 and CXCL10 expression strongly correlate with disease activity, whereas CXCL10 alone correlates with severity, supporting them as potential biomarkers for following disease progression. Further studies in both our mouse model and human patients showed that keratinocytes were the major chemokine producers throughout the course of disease, and functional studies using a conditional signal transducer and activator of transcription (STAT)-1 knockout mouse showed that IFN-γ signaling in keratinocytes was critical for disease progression and proper autoreactive T-cell homing to the epidermis. In contrast, epidermal immune cell populations including endogenous T cells, Langerhans cells, and γδ T cells were not required. These results have important clinical implications, because topical therapies that target IFN-γ signaling in keratinocytes could be safe and effective new treatments, and skin expression of these chemokines could be used to monitor disease activity and treatment responses.

    Vitiligo is an idiopathic systemic autoimmune disease affecting skin, hair and oral mucosa. This genetic yet acquired disease characterized by melanin loss is a cause of morbidity across all races. Though thyroid disturbance has been recognized as a key trigger of this pathology, an array of other factors plays critical role in its manifestation. Multiple hormones (corticotropin-releasing hormone, adrenocorticotropic hormone, α-melanocyte-stimulating hormone, melatonin, calcitriol, testosterone, estrogen), genes (Human leukocyte antigen (HLA), Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4), Forkhead box D3 (FOXD3), Cluster of differentiation 117 (CD117), Estrogen receptor (ESR) 1, Cyclooxygenase-2 (COX2), Vitiligo-associated protein 1 (VIT1)), and lifestyle choices (stress, diet, cosmetic products, and medications) have been suspected as drivers of this disorder. The pathological mechanisms have been understood in recent times, with the aid of genomic studies; however a universally-effective therapy is yet to be achieved. This review discusses these under-investigated facets of vitiligo onset and progression; hence, it is expected to enrich vitiligo research. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Vitiligo is characterized by depigmented skin patches due to loss of epidermal melanocytes. Oxidative stress may play a role in vitiligo onset, while autoimmunity contributes to disease progression. In this study we sought to identify mechanisms that link disease triggers and spreading of lesions. A hallmark of melanocytes at the periphery of vitiligo lesions is dilation of the endoplasmic reticulum (ER). We hypothesized that oxidative stress results in redox disruptions that extend to the ER, causing accumulation of misfolded peptides, which activates the unfolded protein response (UPR). We used 4-tertiary butyl phenol (4-TBP) and monobenzyl ether of hydroquinone (MBEH), known triggers of vitiligo. We show that expression of key UPR components, including the transcription factor X-box binding protein 1 (XBP1), are increased following exposure of melanocytes to phenols. XBP1 activation increases production of immune mediators interleukin-6 (IL6) and IL8. Co-treatment with XBP1 inhibitors reduced IL6 and IL8 production induced by phenols, while over-expression of XBP1 alone increased their expression. Thus, melanocytes themselves produce cytokines associated with activation of an immune response following exposure to chemical triggers of vitiligo. These results expand our understanding of the mechanisms underlying melanocyte loss in vitiligo and pathways linking environmental stressors and autoimmunity. PMID:22696056

    Full Text Available Background: Several modalities of treatment have been tried in vitiligo with varied results; however, Indian data on comparative studies of two or more therapies are limited. Aims: We compared different phototherapy methods with an oral steroid as an adjunct to determine the method with the best tolerability and efficacy. Methods: Eighty-six patients with progressive vitiligo were randomly assigned to different study groups according to a continuous selection method over a period of one year. Group 1 was given OMP + PUVA, group 2 OMP + UVB (NB, group 3 OMP + UVB (BB and group 4 was given OMP alone. Each patient was followed up for six months and then released from treatment. Clinical evaluation was made at the end of three and six months. Results: In group 1 (OMP + PUVA, marked improvement was seen in 18.51% while moderate improvement was seen in 66.66% of the patients. Marked improvement was seen in 37.03% in group 2 (OMP + NB-UVB while 44.44% had moderate improvement. In group 3 (OMP + BB UVB, 8.33% showed marked improvement while moderate improvement was seen in 25% of the patients. Marked and moderate improvement was seen in 5 and 10% of group 4 (OMP patients, respectively. Conclusions: Our study compared four treatment modalities in vitiligo patients, out of which oral minipulse of steroids (OMP only had an adjunct value and was not very effective by itself. Narrow band UVB has a definite edge over broad band UVB and should be preferred when both options are available. NB-UVB and PUVA showed comparable efficacy.

    2012-06-01

    Full Text Available We reported here two cases of vitiligo vulgaris successfully treated with the combination therapy of topical steroid and vitamin D3 compound and currently maintained by vitamin D3 analog without any adverse effects: skin atrophy, striae or telangiectasia on the exposed areas. The best-known mechanism of topical vitamin D3 analog is the enhancement of keratinocytes differentiation and anti-proliferative effects. Vitamin D3 analog is also reported to suppress T-cell mediated immunity, T-cell skin recruitment, and skin infiltration via down-regulating cutaneous lymphocyte antigen expression. Furthermore, vitamin D3 compounds are known to influence melanocyte maturation and differentiation and also to up-regulate melanogenesis. Autoreactive lymphocytes against melanocytes are one of the causes. Topical vitamin D3 analog may control vitiligo itself, however stronger immunosuppressive effects of topical corticosteroid may contribute to rapid re-pigmentation suppressing auto-reactive lymphocytes. The topical combination therapy is a simple, effective and safe option for vitiligo vulgaris in sun-exposed areas.

    2015-01-01

    Summary For decades, research in autoimmunity has focused primarily on immune contributions to disease. Yet recent studies report elevated levels of reactive oxygen species (ROS) and abnormal activation of the unfolded protein response (UPR) in cells targeted by autoimmunity, implicating cellular stress originating from the target tissue as a contributing factor. A better understanding of this contribution may help to answer important lingering questions in organ-specific autoimmunity, like what factors initiate disease, and what directs its tissue specificity. Vitiligo, an autoimmune disease of the skin, has been the focus of translational research for over 30 years, and both melanocyte stress and immune mechanisms have been thought to be mutually exclusive explanations for pathogenesis. Chemical-induced vitiligo is a unique clinical presentation that reflects the importance of environmental influences on autoimmunity, provides insight into a new paradigm linking cell stress to the immune response, and serves as a template for other autoimmune diseases. In this review I will discuss the evidence for cell stress contributions to a number of autoimmune diseases, the questions that remain, and how vitiligo, an underappreciated example of organ-specific autoimmunity, helps to answer them.

    Full Text Available Background and Aims: Stable vitiligo can be treated by various surgical procedures. Non-cultured melanocyte grafting techniques were developed to overcome the time-consuming process of culture while at the same time providing acceptable results. All the techniques using non-cultured melanocyte transfer involve trypsinisation as an integral step. Jodhpur technique used by the author is autologous, non-cultured, non-trypsinised, epidermal cell grafting. Settings and Design: The study was conducted on patients visiting the dermatology outpatient department of a tertiary health centre in Western Rajasthan. Materials and Methods: At the donor site, mupirocin ointment was applied and dermabrasion was done with the help of micromotor dermabrader till pinpoint bleeding was seen. The paste-like material obtained by this procedure containing melanocytes and keratinocytes admixed with the ointment base was harvested with spatula and was subsequently spread over the recipient area. Recipient site was prepared in the same manner by dermabrasion. After 10 days, dressing at both sites was removed taking utmost care at the recipient site as there was a theoretical risk of dislodging epidermal cells. Results: In a study of 437 vitiligo patches, more than 75% re-pigmentation (excellent improvement was seen in 41% of the patches. Lesions on thigh (100%, face (75% and trunk (50% showed maximal excellent improvement, whereas patches on joints and acral areas did not show much improvement. Conclusions: This technique is a simplified, cost effective, less time-consuming alternative to other techniques which involve tryspsinisation of melanocytes and at the same time provides satisfactory uniform pigmentation.

  1. Demonstration of tyrosinase in the vitiligo skin of human beings by a sensitive fluorometric method as well as by 14C(U)-L-tyrosine incorporation into melanin

    Tyrosinase activity (Monophenol, dihydroxyphenylalanine: oxygen oxidoreductase EC 1.14.18.1) in vitiligo and normal epidermal homogenates of skin from human beings was measured by estimating beta 3,4-dihydroxyphenylalanine (dopa) by a highly sensitive fluorometric method described in this paper. The tyrosine activity in the vitiligo skin was about 4 to 37% of corresponding normal skin. The activity of tyrosinase in normal human skin from different individuals and from different regions of the body was in the range of 4 to 140 picomoles of beta 3,4-dihydroxyphenylalanine formed per min/mg protein of epidermal homogenate. The enzyme from vitiligo and normal skin was severely inhibited by substance(s) of low molecular weight. The enzyme exhibits a lag of about 4 hr in the absence of added beta 3,4-dihydroxyphenylalanine and 1 hr in presence of 5 microM dopa. Tyrosinase from the normal and vitiligo skin was inhibited by excess concentration of tyrosine. The homogenates from vitiligo skin could synthesize melanin from C14(U)-L-Tyrosine. The rate of tyrosine incorporation into melanin by the epidermal homogenates is increased by 3,4-dihydroxyphenylalanine (dopa) disproportionate to its effect on tyrosinase activity. Based on the data presented in this paper it is concluded that melanocytes are present in the vitiligo skin. A tentative hypothesis is put forward to explain the lack of melanin synthesis by the vitiligo skin under in vivo conditions, although melanocytes are present

    Full Text Available Oral 8-MOP and TMP were compared in the PUVA therapy for vitiligo. Group A (25 cases was initiated on 0.3 mg/kg of 8-MOP with 1/2 Joule/cm2 of UVA and weekly increments of 1/2 Joule/ cm2 and Group B was started on 0.6 mg/kg of TMP with 1 Joule/cm2 of UVA and weekly increments of 1 Joule/cm2. Therapy was given thrice a week. Repigmentation was evaluated by using a 0-6 scale. At the end of 60 sittings, on acceptable cosmetic response was seen over the face, neck and upper extremities in both groups, while trunk and lower extremities showed lesser response. 8-MOP gave earlier response, needing a lower cumulative UVA dose i.e. 75 J/cm2 as compared to TMP i.e. 106 J/cm2. Phototoxicity was seen more often with 8-MOP. In conclusion, in Indians, 8-MOP is the drug of choice in PUVA therapy of vitiligo provided precautions against phototoxicity are adequate.

    Vitiligo is a de-pigmenting skin disorder characterized by white patches on skin due to partial or complete loss of melanocytes. Psoralen in combination with ultraviolet-A (PUVA) acts by stimulation of melanin content and tyrosinase activity in melanocytes. Resveratrol, a sirtuin activator and a potential anti-oxidant reduce oxidative stress which is one of the triggering factors for initiation of vitiligo. Despite their therapeutic activity, weak percutaneous permeability of psoralen and poor solubility of resveratrol hinders their effective topical administration. The aim of present study is to formulate ultradeformable liposomes (UDL) co-loaded with psoralen and resveratrol for evaluation of PUVA and anti-oxidant combination in vitiligo treatment. For this purpose, UDL composed of DC-Chol, cholesterol and sodium deoxy cholate were prepared for their co-delivery. Liposomal carriers were characterized and evaluated for their efficacy using B16F10 cell line. Free radical scavenging potential was also determined for these carriers by in vitro anti-oxidant assays. Optimal co-loaded UDL with particle size ranging from 120 to 130nm, zeta potential of +46.2mV, entrapment efficiency of 74.09% (psoralen) and 76.91% (resveratrol) were obtained. Compared to control, co-loaded UDL showed significant stimulation of melanin and tyrosinase activity with major contribution of psoralen. Further, co-loaded UDL also exhibited potential free radical scavenging activity where resveratrol played a key role. Hence, psoralen and resveratrol co-loaded UDL acts in vitiligo through dual mechanisms of action viz., stimulation of melanin and tyrosinase activity as well as by anti-oxidant activity. These findings indicate that psoralen and resveratrol co-loaded UDL has the promising therapeutic potential for the treatment of vitiligo. Copyright © 2017 Elsevier B.V. All rights reserved.

    Vitiligo is an immune-related disease with patchy depigmentation of skin and hair caused by selective destruction of melanocytes. In recent decades, many studies have shown the association between vitiligo and HLA genes; however, the results of Han Chinese are scarce. In this study, we performed a fine-mapping analysis of the MHC region in 2818 Han Chinese subjects through a widely used HLA imputation method with a newly built large-scale Han-MHC reference panel. Three new four-digit HLA alleles (HLA-DQB1 ∗ 02:02, HLA-DQA1 ∗ 02:01 and HLA-DPB1 ∗ 17:01) were identified to be associated with the risk of vitiligo, and four previously reported alleles were confirmed. Further conditional analysis revealed that two important variants, HLA-DQβ1 amino acid position 135 (OR = 1.79, P = 1.87 × 10 -11 ) and HLA-B amino acid positions 45-46 (OR = 1.44, P = 5.61 × 10 -11 ), conferred most of the MHC associations. Three-dimension ribbon models showed that the former is located within the β2 domain of the HLA-DQβ1 molecule, and the latter lies in the α1 domain of the HLA-B molecule, while both are involved in specific antigen presenting process. Finally, we summarized all significant signals in the MHC region to clarify their complex relationships, and 8.60% of phenotypic variance could be explained based on all reported variants in Han Chinese so far. Our findings highlight the complex genetic architecture of the MHC region for vitiligo in Han Chinese population and expand our understanding of the roles of HLA coding variants in the etiology of vitiligo.

    Vitiligo, characterised by progressive melanocyte death, can be initiated by exposure to vitiligo-inducing phenols (VIPs). VIPs generate oxidative stress in melanocytes and activate the master antioxidant regulator NRF2. While NRF2-regulated antioxidants are reported to protect melanocytes from oxidative stress, the role of NRF2 in the melanocyte response to monobenzone, a clinically relevant VIP, has not been characterised. We hypothesised that activation of NRF2 may protect melanocytes from monobenzone-induced toxicity. We observed that knockdown of NRF2 or NRF2-regulated antioxidants NQO1 and PRDX6 reduced melanocyte viability, but not viability of keratinocytes and fibroblasts, suggesting that melanocytes were preferentially dependent upon NRF2 activity for growth compared to other cutaneous cells. Furthermore, melanocytes activated the NRF2 response following monobenzone exposure and constitutive NRF2 activation reduced monobenzone toxicity, supporting NRF2's role in the melanocyte stress response. In contrast, melanocytes from individuals with vitiligo (vitiligo melanocytes) did not activate the NRF2 response as efficiently. Dimethyl fumarate-mediated NRF2 activation protected normal and vitiligo melanocytes against monobenzone-induced toxicity. Given the contribution of oxidant-antioxidant imbalance in vitiligo, modulation of this pathway may be of therapeutic interest. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Two men reported previously with vitiligo after occupational exposure to hydroquinone monomethyl ether (HMME) have been reviewed after eight years. Repigmentation of significant degree was found in one man and of limited degree in the other. One hundred and sixty-nine men in the same works have been screened with Wood's light for evidence of vitiligo. No cases were found in the 148 men exposed to HMME (colleagues who screened 100 men exposed to HMME in two other factories also found no case) or in the 129 who had been exposed to paratertiary-amyl-phenol. Loss of light reflection on Wood's light examination was observed in 13 men due to scars or to other skin disorders.

    Vitiligo is an autoimmune disease, characterized by progressive loss of skin pigmentation, which is caused by the interactions of multiple factors, such as heredity, immunity and environment. Recently, a single nucleotide polymorphism (SNP) rs638893 at 11q23.3 region was identified as a risk factor for vitiligo in genome-wide association studies and multiple SNPs in this region have been associated with other autoimmune diseases. This study aims to identify additional susceptibility variants associated with vitiligo at 11q23.3 in the Chinese Han population. We selected and genotyped 26 SNPs at 11q23.3 in an independent cohort including 2924 cases and 4048 controls using the Sequenom MassArray iPLEX ® system. Bonferroni adjustment was used for multiple comparisons and P value vitiligo (OR=1.21, 95% CI: 1.11-1.31, P=1.20×10 -5 ; OR=1.14, 95% CI: 1.07-1.23, P=1.90×10 -4 , respectively). The C allele of rs638893 (a previously reported one) located upstream of DDX6 was also significantly associated with vitiligo (OR=1.25, 95% CI: 1.12-1.38, P=3.04×10 -5 ). The genotypes distribution of 3 SNPs also showed significant differences between case and control (rs613791: P=7.00×10 -6 , rs523604: P=4.00×10 -3 , rs638893: P=1.20×10 -5 , respectively). The two newly identified SNPs (rs613791 and rs523604) showed independent associations with vitiligo by linkage disequilibrium analysis and conditional logistic regression. The study identified two new independent signals in the associated locus 11q23.3 for vitiligo. The presence of multiple independent variants emphasizes an important role of this region in disease susceptibility. Copyright © 2017 Japanese Society for Investigative Dermatology.

    The localized scleroderma (LS) known as morphea, presents a variety of clinical manifestations that can include systemic involvement. Current classification schemes divide morphea into categories based solely on cutaneous morphology, without reference to systemic disease or autoimmune phenomena. This classification is likely incomplete. Autoimmune phenomena such as vitiligo and Hashimoto thyroiditis associated with LS have been reported in some cases suggesting an autoimmune basis. To our knowledge this is the first case of a morphea forming part of a multiple autoimmune syndrome (MAS) and presenting simultaneously with autoimmune thrombocytopenic purpura and central nervous system vasculitis. We report an uncommon case of a white 53 year old female patient with LS as part of a multiple autoimmune syndrome associated with pneumonitis, autoimmune thrombocytopenic purpura and central nervous system vasculitis presenting a favorable response with thrombopoietin receptor agonists, pulses of methylprednisolone and cyclophosphamide. Is likely that LS have an autoimmune origin and in this case becomes part of MAS, which consist on the presence of three or more well-defined autoimmune diseases in a single patient.

    Vitiligo is a CD8 T cell-mediated autoimmune disease that has been shown to promote the longevity of memory T cell responses to melanoma. However mechanisms whereby melanocyte/melanoma antigen-specific T cell responses are perpetuated in the context of vitiligo are not well understood. The present studies investigate the possible phenomenon of naïve T cell priming in hosts with melanoma-initiated, self-perpetuating, autoimmune vitiligo. Using naïve pmel (gp10025-33-specific) transgenic CD8 T cells, we demonstrate that autoimmune melanocyte destruction induces naive T cell proliferation in skin-draining lymph nodes, in an antigen-dependent fashion. These pmel T cells upregulate expression of CD44, P-selectin ligand, and granzyme B. However, they do not downregulate CD62L, nor do they acquire the ability to produce IFN-γ, indicating a lack of functional priming. Accordingly, adult thymectomized mice exhibit no reduction in the severity or kinetics of depigmentation or long-lived protection against melanoma, indicating that the continual priming of naïve T cells is not required for vitiligo or its associated anti-tumor immunity. Despite this, depletion of CD4 T cells during the course of vitiligo rescues the priming of naïve pmel T cells that are capable of producing IFN-γ and persisting as memory, suggesting an ongoing and dominant mechanism of suppression by regulatory T cells. This work reveals the complex regulation of self-reactive CD8 T cells in vitiligo, and demonstrates the overall poorly immunogenic nature of this autoimmune disease setting. PMID:24403535

    Rosacea is a chronic inflammatory dermatosis affecting >2% of the population. Willingness to pay (WTP) is a well established method which reflects the individual burden of disease. Evaluation of WTP and quality of life (QoL) in patients with rosacea. Nationwide postal survey on adult patients with rosacea affiliated with the German rosacea patient advocacy group. WTP was evaluated by three standardized items and compared to historical data on vitiligo (n = 1023). QoL was assessed using the Dermatology Life Quality Index (DLQI). Data from n = 475 rosacea patients (79.9% women, mean age 56.3, range 26-90) were analysed. On average, patients were willing to pay € 2880 (median € 500) for complete healing compared with € 7360 (median € 3000) in vitiligo. Relative WTP was higher in women; the highest sums were registered for the age group 21-30 years. The extent of facial involvement predicted a higher relative WTP, whereas WTP decreased with the duration of symptoms and age. Mean DLQI total score was 4.3 compared to 7.0 in vitiligo. In rosacea, the highest values were observed in patients 10) were less frequent (11%) than in vitiligo (24.6%). The correlation between WTP and DLQI was significant (e.g. r = 0.249, P = 0.000 for relative WTP). Rosacea patients show a moderate WTP and average QoL reduction is mild. WTP proved to be a valid tool to assess patients' burden of disease. Patient education and the development of effective treatment options might still improve patients' satisfaction. © 2012 The Authors.

    Conclusion: CT findings of tuberculosis in diabetic patients are different from those in non-diabetic patients, with a higher occurrence of non-segmental distribution and multiple cavities within a tuberculous lesion. By follow-up re-examination, diabetic patients show a slower and unobvious therapeutic response on CT scans compared to non-diabetic patients. CT can provide important information for the diagnosis and management of TB in diabetic and non-diabetic patients.

    Autoimmune polyendocrine syndrome (APS) is the association of autoimmune endocrine diseases, with other autoimmune nonendocrine disorders. APS types 1, 2 and 4 include autoimmune adrenalitis; this suggests the presence of autoantibodies. A specific serological marker for these is the anti 21- hydroxilase autoantibody (a21-OH). APS type 2 is the association of autoimmune adrenalitis, to autoimmune thyroid disease and/or diabetes mellitus, all these are induced by autoantibodies. Alopecia, vitiligo, myasthenia and other manifestations can be minor components. We sought to establish the prevalence of seric a21-OH in patients with positive anti-microsomal fraction autoantibodies, autoimmune thyroid disease and/or non-endocrine autoimmune diseases. We also aimed to diagnose incomplete forms of APS and to follow up patients at risk of progression to complete forms of APS. A population of 72 patients and another of 60 controls with negative anti-microsomal fraction autoantibodies were studied. Elevated seric a21-OH were found in two patients. Patient A with 47 U/ml had autoimmune hypothyroidism and myasthenia; and patient B with 8.75 U/ml had autoimmune hypothyrodism and vitiligo; they both lacked adrenal insufficiency. Seric a21-OH had a prevalence of 2.8%. Regarding the adrenal component, patients A and B had an incomplete and latent APS type 2. Considering a21-OH as markers of latent endocrine autoimmune diseases and taking into account the eventual risk of developing clinical manifestations, periodic biochemical and clinical follow-ups are recommended.

    Atopic dermatitis (AD) is a frequent and burdensome disease. The objectives of this study were (1) to assess the willingness to pay (WTP) and quality of life (Qol) in AD patients and (2) to compare the results with data on other chronic skin diseases. To collect data, a non-interventional, cross-sectional nationwide postal survey on adult patients with clinically diagnosed AD was performed; socio-demographic data, clinical features/symptoms, WTP and QoL were recorded. WTP was assessed in three different approaches, including relative and absolute figures. Data from n = 384 AD patients (mean age 42.0, range 18-92, 69.8 % female) were analyzed. WTP for complete healing was on median 1,000 (average 11,884) and exceeded WTP in rosacea (median 500) but not in vitiligo (median 3,000). Mean Dermatology Life Quality Index (DLQI) was 8.5 (vitiligo 7.0; psoriasis 6.7; rosacea 4.3) and correlated with pruritus, xerosis and disturbed sleep. WTP and DLQI correlated only marginally (r s = 0.134, p = 0.01). In conclusion, AD patients show high WTP and markedly reduced QoL compared to other chronic skin diseases.

    Certain skin conditions, such as vitiligo, acne, vascular malformations, and surgical scars, can impair the quality of life of pediatric patients, especially adolescents-even to the point of hindering psychosocial development. We review the cases of 6 patients with discoloration or scarring, predominantly of the face, who attended our cosmetic camouflage workshops from January through December 2012. The quality-of-life impact of their skin disorder was assessed before and after workshop attendance. Cosmetic camouflage is an easily replicated, cheap, and noninvasive adjunctive treatment of great potential value in managing skin conditions that impair the physical and emotional well-being of pediatric patients.

    Systemic sclerosis (SSc) is a rare and potentially life threatening autoimmune disorder. The burden of disease compared to other dermatoses is unknown. The purpose of this study was to assess both the quality of life in patients with SSc and the variables that are associated with poor quality of life. Forty-one patients with systemic sclerosis (29 limited, 2 diffuse, 10 undifferentiated forms) were assessed with respect to their health status and compared to published data for the normal population, SSc patients from other studies, and patients with chronic skin diseases. For the most part, our SSc patients had better outcomes in all 8 dimensions of the SF-36 than SSc patients from other studies, and poorer scores than the healthy population and those with occupational contact dermatitis, ichthyosis, non-melanoma skin cancer, contact dermatitis, atopic eczema, chronic nail disease, vitiligo, health care workers with work-related disease, and those with other chronic skin diseases, but significantly better scores for mental health than those with nail disease, vitiligo, and health-care workers. Patients with atopic dermatitis, psoriasis and pemphigus had significantly poorer mean scores in social function and mental health than SSc patients. Patients with pemphigus were also significantly impaired in their physical and emotional roles. Patients with systemic lupus erythematosus (SLE) had the significantly poorest mean scores for QoL in all 8 domains except bodily pain and emotional role. Besides SLE, SSc is one of the most severe chronic dermatologic diseases in terms of reduced QoL. Since SSc cannot be cured, treatment strategies should include therapeutic interventions such as psychotherapy, social support, physiotherapy, and spiritual care. Their beneficial effects could be studied in future.

    Full Text Available O objetivo deste estudo foi comparar a acurácia dos modelos polinomiais não segmentados do quinto grau e de Hradetzky de 1976 e os segmentados de Max e Burkhart de1976 e Clark et al. de 1991, na estimativa dos diâmetros ao longo do fuste de Tectona grandis L.f., com ajustes para o conjunto total dos dados e por classe de diâmetro, em um povoamento com 16 anos, na região centro- sul matogrossense. A base de dados foi composta por 114 árvores, cubadas pela metodologia de Hohenadl modificada e distribuídas em classes de diâmetro. O ajuste dos modelos foi avaliado em função do coeficiente de determinação corrigido, erro padrão da estimativa e pela distribuição dos resíduos em porcentagem. A acuracidade dos modelos ao longo do fuste foi avaliada pelo desvio, desvio padrão das diferenças, somatório de quadrado dos resíduos relativos e a porcentagem dos resíduos. A Equação de Hradetzky foi a que apresentou o melhor ajuste para estimar os diâmetros ao longo do fuste de Tectona grandis tanto para o conjunto total dos dados quanto para as classes de diâmetro com os menores valores nas estatísticas auxiliares, exceto na Classe 3, onde a equação selecionada foi a de Clark et al.

    To evaluate the CT features of pulmonary tuberculosis in diabetic or immunocompromised patients, we reviewed CT of the chest in 42 adult patients with active pulmonary tuberculosis. Forty-two had some underlying diseases or immunocompromised conditions (31 diabetes mellitus, 6 malignancies, 2 long-term steroid therapy, 2 pneumoconiosis, and one anorexia nervosa). In diabetic or immunocompromised patients, a high incidence of non-segmental distribution (27%) and multiple small cavities in a cavitary lesion (45%) was observed. Unusual localization of the lesions such as lower lung field disease was observed in 18% of cases (the incidence of unusual localization in patients with no underlying disease was equal to diabetic or immunocompromised patients).

    Full Text Available Post Kala Azar Dermal Leishmaniasis (PKDL occurs as dermal consequence of previous Visceral Leishmaniasis (VL infection and serves as an important reservoir for transmission of VL. Diagnosis of PKDL is often challenging for its symptomatic resemblance to other co-endemic diseases like Leprosy or Vitiligo. Parasitological examination by slit-skin smear and culture are the standard methods but lack high sensitivity. Thus, for efficient control of VL, reliable diagnostic and prognostic assay of PKDL are required.Previously, glycoproteins (9-OAcSA have been reported as promising biomarkers of Indian VL patients. However, till date, the status of glycans in Indian PKDL patients remains unexplored. Accordingly, in this study, the glyco-profile of PKDL Circulating Immune Complexes (CICs as compared to other cross diseases like Vitiligo and Leprosyhas been investigated. Further, a novel Glyco CIC assay has been developed for efficient Indian PKDL patient diagnosis.In the present study, 90 PKDL patients were enrolled from 3 VL endemic districts of West Bengal during 2015-16. Glycosylation profile of isolated CICs from sera of PKDL patients were initially analyzed through gradient SDS gel electrophoresis followed by PAS silver double staining, which revealed the presence of several glycan rich PKDL specific proteins of varying molecular weights. To further characterize the glyco-profile of acid dissociated affinity purified immuno-reactive antigens present in the CICs, glycosylation was demonstrated in these purified CIC antigens by DIG glycan differentiation kit with or without glycosidase as well as neuraminidase treatment. Diagnostic evaluation of the newly developed colorimetric Glyco CIC assay through Receiver Operating Characteristic (ROC curve analysis revealed excellent (0.99 AUC value as compared to other conventional serodiagnostic assays like PEG CIC, Parasite ELISA (IgG and IgM. Additionally, longitudinal monitoring of 18 PKDL patients further

    Full Text Available Ring chromosome 18 has a highly variable phenotype, depending on the extent of distal arm deletions. It is most commonly presented as a combination of 18p- and distal 18q- syndrome. IgA deficiency and autoimmune diseases have been previously described in these patients. Seven cases of juvenile rheumatoid arthritis (JRA have been reported. Here we report the first case of late onset rheumatoid arthritis (RA in a 32 year old Dominican woman with hypothyroidism, vitiligo, IgA deficiency, interstitial lung disease (ILD, cystic bronchiectasis, and features consistent with ringed 18, 18p- and distal 18q syndrome.  The multiple autoimmune findings in our patient lends further support to the idea of loci on chromosome 18 playing a role in autoimmune disease expression. Late onset RA and ILD in a patient with chromosome 18 abnormalities are novel findings and are additional conditions to be aware of in this population.

    Diabetes type 1(T1D) is the most frequent form of diabetes in children and young people, which essence is autoimmune destruction of pancreatic B cells islet. Co-occurrence of other autoimmune diseases is observed in children with T1D, the most often are: Hashimoto disease or coeliac disease. We report the case of the patient, who presents coincidence of T1D with other rare autoimmune diseases such as: Graves - Basedow disease, myasthenia gravis, vitiligo and IgA deficiency. All mentioned diseases significantly complicated both endocrine and diabetic treatment of our patient and they negatively contributed her quality of life. The clinical picture of the case allows to recognize one of the autoimmune polyendocrine syndromes: APS-3 and is associated with still high risk of developing another autoimmune disease. © Polish Society for Pediatric Endocrinology and Diabetology.

  14. Patient-assisted teledermatology practice: What is it? When, where, and how it is applied?

    Full Text Available Recent teledermatology practice has been focused on different models made possible by robust advances in information technology leading to consistent interaction between the patient and health care professionals. Patient-assisted teledermatology practice also called patient-enabled teledermatology or home based teledermatology is one such novel model. There is a lack of scientific literature and substantive reviews on patient-assisted teledermatology practice. The present article reviews several studies and surveys on patient-assisted teledermatology practice and outlines its advantages and barriers to clinical utility and analyses the potentiality of this concept. Incorporating patient-assisted teledermatology practice as a novel model in the revised classification of teledermatology practice is proposed. In patient-assisted teledermatology, the patient can upload his/her clinical images as a first contact with the dermatologist or an initial face-to-face examination can be followed by teledermatology consultations. The latter method is well suited to chronic diseases such as psoriasis, vitiligo, and leg ulcers, which may need frequent follow-up entailing significant costs and time, particularly in the elderly. Teledermatology may also be used by the treating dermatologist to seek expert opinion for difficult cases. Studies have demonstrated the importance and usability of the concept of patient-assisted teledermatology practice. Various teledermatology care models are available and the appropriate model should be chosen depending on whether the clinical situation is that of easily diagnosed cases ("spotters", chronic cases or doubtful cases and difficult-to-manage cases.

    Full Text Available Background and Design: Celiac disease is an immune-mediated enteropathy which develops as a result of exposure to gluten in food products in individuals with a genetic predisposition. Gastrointestinal and extra-gastrointestinal clinical findings can be seen in these patients. An increased frequence of autoimmune diseases has been reported in patients with celiac disease. Some dermatological diseases, such as dermatitis herpetiformis, vitiligo, psoriasis, alopecia areata and recurrent aphthous stomatitis have been reported to be more common among patients with celiac disease. However, there are no controlled studies on this subject. The aim of this study was to identify the mucocutaneous symptoms seen in celiac patients and to compare these findings with a control group. Materials and Methods: Forty-nine celiac patients and 54 age-and sex-matched healthy volunteers were included in the study. In the patient group, celiac disease history, height and weight parameters, the medications of the patients, compliance to a gluten-free diet, concomitant skin disorders and additional illnesses were questioned; height and weight parameters, diagnosed illnesses, and medications were questioned in the control group. Dermatological analyses were performed in all participants. Results: Mucocutaneous findings were found to be present in 38 patients (77.6% in the celiac patient group and in 31 (57.4% individuals in the control group. The presence of mucocutaneous findings in celiac patients was significantly more common than in the control group. While immune-mediated mucocutaneous diseases were detected in 8 celiac patients (16.3%, none of the individuals in the control group had immune-mediated mucocutaneous diseases and a statistically significant difference was found between the two groups. Conclusion: In celiac patients, the frequency of immune-mediated mucocutaneous diseases and all mucocutaneous diseases were found to be increased. Therefore, we suggest

    these are induced by autoantibodies. Alopecia, vitiligo, myasthenia and other manifestations can be minor components. We sought to establish the prevalence of seric a21-OH in patients with positive anti-microsomal fraction autoantibodies, autoimmune thyroid disease and/or non-endocrine autoimmune diseases. We also aimed to diagnose incomplete forms of APS and to follow up patients at risk of progression to complete forms of APS. A population of 72 patients and another of 60 controls with negative anti-microsomal fraction autoantibodies were studied. Elevated seric a21-OH were found in two patients. Patient A with 47 U/ml had autoimmune hypothyroidism and myasthenia; and patient B with 8.75 U/ml had autoimmune hypothyrodism and vitiligo; they both lacked adrenal insufficiency. Seric a21-OH had a prevalence of 2.8%. Regarding the adrenal component, patients A and B had an incomplete and latent APS type 2. Considering a21-OH as markers of latent endocrine autoimmune diseases and taking into account the eventual risk of developing clinical manifestations, periodic biochemical and clinical follow-ups are recommended.

    The risk of skin cancer in patients with alopecia areata (AA) is unknown. While the risk of skin cancer in chronic inflammatory alopecias may be elevated, AA shares many characteristics with vitiligo, an autoimmune illness associated with decreased risk of melanoma and non-melanoma skin cancers. In this retrospective cohort study, we determined the risk of developing skin cancer among patients with AA in a validated cohort relative to matched controls at two tertiary care hospitals in Massachusetts. There was a significantly decreased risk of NMSC in AA patients than controls (OR=0.63, 95% CI=0.48-0.81). There was a trend towards a protective effect of AA associated with melanoma (OR=0.65, 95% CI=0.39-1.09). There was no difference in anatomic distribution of skin cancer between patients with AA and controls. Our study demonstrates a decreased risk of nonmelanoma skin cancer and a trend towards reduced risk of melanoma in patients with AA. Copyright © 2016. Published by Elsevier Ltd.

  19. Coordination of fictive motor activity in the larval zebrafish is generated by non-segmental mechanisms.

    Directory of Open Access Journals (Sweden)

    Timothy D Wiggin

    Full Text Available The cellular and network basis for most vertebrate locomotor central pattern generators (CPGs is incompletely characterized, but organizational models based on known CPG architectures have been proposed. Segmental models propose that each spinal segment contains a circuit that controls local coordination and sends longer projections to coordinate activity between segments. Unsegmented/continuous models propose that patterned motor output is driven by gradients of neurons and synapses that do not have segmental boundaries. We tested these ideas in the larval zebrafish, an animal that swims in discrete episodes, each of which is composed of coordinated motor bursts that progress rostrocaudally and alternate from side to side. We perturbed the spinal cord using spinal transections or strychnine application and measured the effect on fictive motor output. Spinal transections eliminated episode structure, and reduced both rostrocaudal and side-to-side coordination. Preparations with fewer intact segments were more severely affected, and preparations consisting of midbody and caudal segments were more severely affected than those consisting of rostral segments. In reduced preparations with the same number of intact spinal segments, side-to-side coordination was more severely disrupted than rostrocaudal coordination. Reducing glycine receptor signaling with strychnine reversibly disrupted both rostrocaudal and side-to-side coordination in spinalized larvae without disrupting episodic structure. Both spinal transection and strychnine decreased the stability of the motor rhythm, but this effect was not causal in reducing coordination. These results are inconsistent with a segmented model of the spinal cord and are better explained by a continuous model in which motor neuron coordination is controlled by segment-spanning microcircuits.

    Objective: To evaluate CT and X-ray features of pulmonary tuberculosis in diabetic patients, patients post kidney transplantation, and patients with acquired immunodeficiency syndrome (AIDS). Methods: The authors reviewed CT scans in 20 patients with diabetic patients, X-ray films in 10 cases after kidney transplantation, and CT scans in 2 patients with AIDS. Results: CT features of pulmonary tuberculosis in diabetic diseases included larger confluent consolidation (10 cases ), multiple small cavities within any given lesion (9 cases ) and non-segmental distribution (2 cases). Satellite lesions were found in most films. The X-ray appearances of pulmonary tuberculosis post kidney transplantation included patch and larger confluent consolidation (6 cases), and miliary tuberculosis(4 cases). The CT findings of pulmonary tuberculosis with AIDS were enlarged mediastinal lymph nodes (1 case), pulmonary infiltration (1 case), and extra chest lesions(2 cases) such as enlarged neck lymph nodes and post-peritoneal lymph nodes. Conclusion: The Main radiological findings of pulmonary tuberculosis in immunocompromised patients appear larger confluent consolidation, multiple small cavities within a given lesion, miliary tuberculosis, enlarged mediastinal lymph nodes, and extra chest enlarged lymph nodes

    Full Text Available This study chanlcterizes the HLA class I and class II antigens in a group of patients with vitiligo and a control group, both of Dutch descent. Earlier reports had shown a significant positive association with DR4 and a significant negative association with DR3. We found that, after correction for the broad antigens studied, only Cw7 and DR6 were significantly associated with vitiligo. The significant positive association of DR6 with vitiligo is interesting since vitiligo has an autoimmune component in its pathogenesis and DR6 may be a marker for high immune responsiveness.

    Malignant melanoma is potentially life-threatening but in most cases curable if detected early. Willingness to pay (WTP) is a preference-based construct that reflects burden of disease by assessment of the monetary value for a hypothetical cure from disease. Since WTP (directly as total amount of money) has not been assessed so far in patients with low risk melanoma, it was interesting to gain insights in this patient population and then, in a second step, compare it directly with the WTP of their treating dermato-oncologists. WTP was assessed in 125 patients with low-risk melanoma and additionally in 105 treating physicians, asking for the one-time and continuous payments they would be willing to make for a sustainable cure, both as absolute sums and as percentages of monthly income. The median WTP based on one-time payment was €10,000 for patients and €100,000 for physicians; relative numbers were 100% versus 300% of monthly income. For continuous monthly payments, WTP was €500 for patients and €1000 for physicians, relative numbers 25% and 50% of income, respectively. Even after controlling for income differences, there was a significantly higher WTP in physicians for all four questions. Compared to patients with chronic skin diseases such as vitiligo, rosacea, atopic eczema and psoriasis, patients with low-risk melanoma showed a significantly higher WTP. Our data suggest that there is a relevant burden of disease even in patients with low-risk tumors. Higher WTP of physicians underlines the prevalence of differences in disease perception.

    We report 3 cases of durable complete response (CR) in patients with BRAF-mutated metastatic melanoma who were initially treated unsuccessfully with sequential immunotherapies (high dose interleukin 2 followed by ipilimumab with or without concurrent radiation therapy). After progression during or post immunotherapy, these patients were given BRAF inhibitor therapy and developed rapid CRs. Based on the concomitant presence of autoimmune manifestations (including vitiligo and hypophysitis), we postulated that there was a synergistic effect between the prior immune therapy and the BRAF targeting agents. Accordingly, the inhibitors were gradually weaned off beginning at 3 months and were stopped completely at 9-12 months. The three patients remain well and in CR off of all therapy at up to 15 months radiographic follow-up. The institution of the BRAF therapy was associated with development of severe rheumatoid-like arthritis in 2 patients which persisted for months after discontinuation of therapy, suggesting it was not merely a known toxicity of BRAF inhibitors (arthralgias). On immunologic analysis, these patients had high levels of non-T-regulatory, CD4 positive effector phenotype T-cells, which persisted after completion of therapy. Of note, we had previously reported a similar phenomenon in patients with metastatic melanoma who failed high dose interleukin-2 and were then placed on a finite course of temozolomide with rapid complete responses that have remained durable for many years after discontinuation of temozolomide. We postulate that a finite course of cytotoxic or targeted therapy specific for melanoma given after apparent failure of prior immunotherapy can result in complete and durable remissions that may persist long after the specific cytotoxic or targeted agents have been discontinued suggesting the existence of sequence specific synergism between immunotherapy and these agents. Here, we discuss these cases in the context of the literature on

    Full Text Available Background: Suction blister grafting is a useful modality of treatment of patients with resistant and stable vitiligo. However, there have been no detailed studies to find out the best donor site for blister formation. Methods: The study was conducted between the period of October 2004 and February 2005 in the dermatology department at a tertiary care center. Nine patients with vitiligo (focal vitiligo, 3; mucosal vitiligo, 2; acrofacial vitiligo, 2; vitiligo vulgaris, 1; and segmental vitiligo, 1 were selected for blister harvesting and grafting. The blisters were raised using the method described by Gupta et al. Results: Suction blisters were attempted to be raised at 52 sites, but only 38 blisters could be raised, 24 complete and 14 incomplete. Blisters were raised in all the three cases on the flexor aspect of the arm (100%, 15 of 17 cases (88.2% on the flexor aspect of the forearm, 4 of 5 cases (80% on the abdomen, 11 of 16 cases (68.7% on the anterolateral thigh, and less frequently over leg or foot. Complete blisters were formed in 13/15 cases (86.6% on the flexor aspect of the forearm, 6/11 cases (54.5% on the anterolateral thigh, and in all cases over leg. Conclusion: The flexor aspect of the forearm is a good site for suction blister harvesting.

    Introduction. Melanoma is now considered an epidemic around the world. Its high lethality, constitutes a serious problem despite the continuous pharmacological and technological advances. NeuGcGM3/VSSP is a vaccine formulation containing ganglioside NeuGcGM3 incorporated in the acting of Neisseria meningitidis. It may be a choice therapeutic given this ganglioside in primary melanoma expression and immunogenicity and safety demonstrated by this vaccine in advanced breast cancer. This study evaluated the safety, immunogenicity and the anti-tumor response in patients with advanced melanoma to manage it via IM or SC. Material and methods: The expression of ganglioside in primary melanomas and its metastases was identified by immunohistochemical methods with the AcM 14F7 (anti-NGCGM3). 2 clinical trials Phase Ib/IIa escalation of doses with NeuGcGM3 /VSSP were conducted in patients with melanoma Advanced IM and SC routes. Safety and anti-tumour response were evaluated with the CTC and RECIST criteria. The statistical analysis was performed with the SPSS statistical package. Results: NeuGcGM3 is expressed in primary tumors and the studied lymph nodes metastases. NeuGcGM3/VSSP was safely managed by the SC and IM, roads without limiting toxicity. Immunogenic with IgM and IgG isotype antibody response resulted in 75% patients. There was anti-tumoral response in 38.5% with increase in median SV mainly associated with anti-tumor response. The appearance of vitiligo and the response of antibodies against other not present in the vaccine formulation gangliosides may be considered a manifestation of immune restoration. Conclusions. NeuGcGM3/VSSP managed IM and SC in patients with advanced melanoma was safe, immunogenic and antitumor activity associated with overall survival advantage. (author)

    Purpose: The aim of this study is to evaluate a possible correlation between areas of lung attenuation, found in minimum intensity projection (Min-IP) reconstruction images performed with high resolution computed tomography without contrast medium (HRCT), and areas of lung perfusion alteration, found in lung perfusion scintigraphy (LPS). Materials and methods: Two independent radiologists, unaware of LPS results, evaluated retrospectively a group of 113 patients affected by pulmonary hypertension (HP) of different aetiology. These have been examined in a period of two years in our centre both by spiral computed tomography (CT) with and without contrast-medium and by LPS. The final diagnosis was determined on clinical data, right heart catheterisation and contrast enhanced CT in angiographic phase (CTPA). We reconstructed the Min-IP images of lung parenchyma in all the cases both in HRCT without contrast-medium, and in contrast enhanced CT in angiographic phase (CTPA) in axial, sagittal and coronal planes. The obtained images were qualitatively graded into three categories of pulmonary attenuation: homogeneous, inhomogeneous with non-segmental patchy defects, inhomogeneous with segmental defects. The same criteria of classification were used also for LPS images. In the group of patients with chronic thromboembolic pulmonary hypertension (CTEPH) we also compared the number of areas of lung attenuation found in Min-IP images in HRCT without contrast-medium, and their exact localization, with not perfused areas in LPS. Gold standard for the diagnosis of pulmonary embolism was spiral contrast enhanced CT in angiographic phase (CTPA). Results: In all cases we found exact correspondence between the Min-IP images in HRCT with and without contras agent. The attenuation pattern seen on Min-IP images was concordant with those of LPS in 96 out of 113 patients (85%). In the remaining 17 cases (15%) it was discordant: in 12 cases inhomogeneous in Min-IP images (7 with non-segmental

    Full Text Available Abstract Background The tumor associated antigen (TAA gp100 was one of the first identified and has been used in clinical trials to treat melanoma patients. However, the gp100 epitope peptide restricted to HLA-A*2402 has not been extensively examined clinically due to the ethnic variations. Since it is the most common HLA Class I allele in the Japanese population, we performed a phase I clinical trial of cancer vaccination using the HLA-A*2402 gp100 peptide to treat patients with metastatic melanoma. Methods The phase I clinical protocol to test a HLA-A*2402 gp100 peptide-based cancer vaccine was designed to evaluate safety as the primary endpoint and was approved by The University of Tokyo Institutional Review Board. Information related to the immunologic and antitumor responses were also collected as secondary endpoints. Patients that were HLA-A*2402 positive with stage IV melanoma were enrolled according to the criteria set by the protocol and immunized with a vaccine consisting of epitope peptide (VYFFLPDHL, gp100-in4 emulsified with incomplete Freund's adjuvant (IFA for the total of 4 times with two week intervals. Prior to each vaccination, peripheral blood mononuclear cells (PBMCs were separated from the blood and stored at -80°C. The stored PBMCs were thawed and examined for the frequency of the peptide specific T lymphocytes by IFN-γ- ELISPOT and MHC-Dextramer assays. Results No related adverse events greater than grade I were observed in the six patients enrolled in this study. No clinical responses were observed in the enrolled patients although vitiligo was observed after the vaccination in two patients. Promotion of peptide specific immune responses was observed in four patients with ELISPOT assay. Furthermore, a significant increase of CD8+ gp100-in4+ CTLs was observed in all patients using the MHC-Dextramer assay. Cytotoxic T lymphocytes (CTLs clones specific to gp100-in4 were successfully established from the PBMC of some

    This article looks at how diagnostic radiographers label their patients. An ethnographic study of the workplace culture in one diagnostic imaging department was undertaken using participant observation for four months and semi-structured interviews with ten key informants. One of the key themes; the way in which radiographers label their patients, is explored in this article. It was found from the study that within the department studied the diagnostic radiographers labelled or categorised their patients based on the information that they had. This information is used to form judgements and these judgements were used to assist the radiographers in dealing with the many different people that they encountered in their work. This categorisation and labelling of the patient appears to assist the radiographer in their decision-making processes about the examination to be carried out and the patient they are to image. This is an important aspect of the role of the diagnostic radiographer. - Highlights: • I have studied the culture in one imaging department. • Radiographers label or categorise their patients. • These labels/categories are used to manage the patient. • This is an important aspect of the way in which radiographers work.

    Full Text Available Background and Purpose: Chronic granulomatous disease (CGD is an inherited disorder of the nicotinamide adenine dinucleotide phosphate (NADPH oxidase complex. This disorder results in recurrent life-threatening bacterial and fungal infections. Aspergillus species are the most common fungal infections in these patients. Case Report: Herein, we present a case of fungal infection in a girl with CGD. We confirmed aspergillosis through the positive microscopic and macroscopic examinations, as well as radiology results. Invasive aspergillosis in this patient with pneumonia, lung abscess, and osteomyelitis of the ribs was not initially treated with amphotericin B (Am B and recombinant interferon-gamma. Conclusion: Among infectious diseases, fungal infections, in particular aspergillosis, remain a serious problem in CGD patients. Considering poor clinical response and deficient immune system, rapid diagnosis of fungal infection and optimizing the treatment of these patients are recommended.

    Full Text Available Background . Complementary and alternative medicine (CAM practices for cancer have become popular among oncology patients. An increasing interest in alternative medicine can be explained by the inefficiency of conventional treatment, dissatisfaction with treating patients like objects, and the will to use all available treatment methods. Objectives . The authors assessed how often patients use CAM methods, and which of them are most popular. Material and methods . The study was conducted in Military Hospital no. 109 and the Independent Public Clinical Hospital no. 1 in Szczecin among 100 chemotherapy patients. This survey-based study was performed using an original questionnaire. Results. Most respondents (68% did not use alternative methods to fight the disease. The most popular treatment methods were: herbal medicine (50%, alternative medicine preparations (38% and diet (25%, and the least common: hypnosis (3% and aromatherapy (3%. Analyzed sociodemographic factors had no effects on a choice of a CAM method. Patients obtained information about CAM methods mainly from the Internet (40%, medical staff (37% and literature (31%. Conclusions . 1. Using CAM by patients receiving chemotherapy for neoplasms is quite a common phenomenon. 2. CAM were more often chosen by women. Neither the duration of the disease nor sociodemographic data had effects on making the decision to use CAM methods. 3. The most popular CAM were: herbal medicine, alternative medicine preparations, and diet. 4. Cancer patients should receive special support from nurses and doctors as well as other members of the therapeutic team. Oncology patients should never be left on their own so that they were forced to seek help and support in therapies unconfirmed by scientific investigation.

    Rathert, Cheryl; Huddleston, Nicole; Pak, Youngju

    2011-01-01

    Patient safety has been a highly researched topic in health care since the year 2000. One strategy for improving patient safety has been to encourage patients to take an active role in their safety during their health care experiences. However, little research has shed light on how patients view their roles. This study attempted to address this deficit by inductively exploring the results of a qualitative study in which patients reported their ideas about what they believe their roles should be. Patients with an overnight stay in the previous 90 days at one of three hospitals were surveyed using a mailing methodology. Of 1,040 respondents, 491 provided an open-ended response regarding what they believe the patient role should be. Qualitative analysis found several prominent themes. The largest proportion of responses (23%) suggested that patients should follow instructions given by care providers. Other prominent themes were that patients should ask questions and become informed about their conditions and treatments, and many implied that they should expect competent care. Our results suggest that patients believe they should be able to trust that they are being provided competent care, as opposed to assuming a leadership role in their safety. Our results suggest that engaging patients in safety efforts may be complex, requiring a variety of strategies. Managers must provide environments conducive to staff and patient interactions to support patients in this effort. Different types of patients may require different engagement strategies.

    Full Text Available Here’s the thing. While I have my asthma under control and my sleeping is no worse than usual, I am still near the uaigh. That’s the word for grave in Irish, and it’s also part of the word for loneliness. I’m near one or the other, or both. There was a time when my health was the only thing I talked about, and my friends from that time ask me now, and I remember that that was the person I was; when health was a fear, because pain was my first language. But what’s really bothering me is the way I use the possessive when it comes to my asthma, my insomnia, my thinning hair, my symptoms. It makes me think I think I am these things. Am I? I wilt therefore I am? If they are me, where will I go if I lose them? I remember when I learned the word ontology – the study of the nature of being. If I am sad, is sad me? If sad is me then what happens when someone treats my sadness? If we were all speaking Irish we would say that sadness is on me. But we’re not. Because when I was five I asked where English came from and my parents introduced me to stair. If we all spoke Irish we would say stair instead of history. But we speak English, mostly, and so stair is relegated to something we use to get up or down, never a story. Did you know that I carry my people’s history in my bones? People didn’t believe me when I said that but then scientists wrote about it, and discovered what was already there — inherited in the blood, the bones, the DNA, the genomes, the chromosomes, like thinning curly hair, like weak lungs, like poetry, like insomnia — and it’s all the rage now, that codified stairstory inside us. Once when I was waiting on a trolley I kept on trying to get up even though I knew I’d fall down. So they put an orderly to mind me. Well, he was there to restrain me, but I didn’t mind. He was young and eager to be seen to be good with patients. I asked him how long his shift had been and he said it was his first. After a bit of this

    Patients demand to be active participants on and partners with the health care team to design their care regimen. Patients bring unique perceptions and expectations and use these to evaluate service quality and satisfaction. If customer satisfaction is not achieved and a patient complaint results, staff must have the skills to respond and launch a service recovery program. Service recovery, when done with style and panache, can retain loyal customers. Achieving patient satisfaction and resolving patient complaints require commitment from top leadership and commitment from providers to dedicate the time to understand their patients' needs.

    Preoperative teaching is an important part of patient care and can prevent complications, as well as promote patient fulfillment during hospitalization. A study was conducted at Alton Ochsner Medical Foundation in New Orleans, LA, in 1989, to determine the impact of a preoperative teaching program on the incidence of postoperative atelectasis and patient satisfaction. Results showed no significant difference of postoperative complications and patient gratification after participating in a structured preoperative teaching program. As part of this study, it was identified that a patient evaluation tool for a preoperative teaching class needed to be developed. The phases of this process are explained in the following article.

    To report the personal experiences of patients undergoing awake craniotomy for brain tumor resection. We carried out a qualitative descriptive survey of patients` experiences with awake craniotomies for brain tumor resection. The survey was conducted through a standard questionnaire form after the patient was discharged from the hospital. Of the 9 patients who met the inclusion criteria and underwent awake craniotomy, 3 of those patients reported no recollection of the operation. Five patients had auditory recollections from the operation. Two-thirds (6/9) reported that they did not perceive pain. Five patients remembered the head clamp fixation, and 2 of those patients classified the pain from the clamp as moderate. None of the patients reported that the surgery was more difficult than anticipated. Awake craniotomy for surgical resection of brain tumors was well tolerated by patients. Most patients reported that they do not recall feeling pain during the operation. However, we feel that further work and exploration are needed in order to achieve better control of pain and discomfort during these types of operations.

However, not all physician-patient relationships follow the normal course and/or meet the natural ends. These abnormal relationships are not inconsequential in terms of numbers and/or their effects (short-term and long term on both patients and physicians. Every country has its own baggage in the wake of why, how and what about these abnormal ends to physician-patient relationships; however, the most common causes are the patients’ inability to pay their medical bills, the conflicting goals of physicians and their patients in regards to patients’ sufferings’ management and finally the behavioral issues (patients’ and/or physicians’ interfering these relationships. Irrespective of any cause, the physicians should never forget that the patient can always discharge their physicians and discontinue their relationship with their physicians without any reason (until unless the physicians deem those patients either incapable/non-consentable to do so and/or potential threat to their own personal safety or other people’s safety.

    Intro: This paper discusses a central professional dilemma in patient-centred education: on one hand the concern for ensuring patients autonomy and right to make their own decisions regarding their treatment and, on the other hand, a concern for getting patients to make the “right” decisions......-centredness is thus promoted as a way to organize health more effectively (in terms of cost and treatment outcomes) and as a way to ensure patients’ autonomy and fundamental right to make their own decisions regarding their treatment. Critical voices within social and nursing theory have however argued....... The paper shows that the programme’s attempt to facilitate that patients make their “own” decision is challenged by patients who understand the preventive programme in relational terms and even demand more intervention from the professionals in terms of expert advice, involvement, and discipline. Conclusion...

    This study aimed to describe patient-handling demands in inpatient units during a 24-hour period at a military health care facility. A 1-day total population survey described the diverse nature and impact of patient-handling tasks relative to a variety of nursing care units, patient characteristics, and transfer equipment. Productivity baselines were established based on patient dependency, physical exertion, type of transfer, and time spent performing the transfer. Descriptions of the physiological effect of transfers on staff based on patient, transfer, and staff characteristics were developed. Nursing staff response to surveys demonstrated how patient-handling demands are impacted by the staff's physical exertion and level of patient dependency. The findings of this study describe the types of transfers occurring in these inpatient units and the physical exertion and time requirements for these transfers. This description may guide selection of the most appropriate and cost-effective patient-handling equipment required for specific units and patients.

    Over 25 years ago, Kubler-Ross identified anger as a predictable part of the dying process. When the dying patient becomes angry in the clinical setting, all types of communication become strained. Physicians can help the angry dying patient through this difficult time by using 10 rules of engagement. When physicians engage and empathize with these patients, they improve the patient's response to pain and they reduce patient suffering. When physicians educate patients on their normal responses to dying and enlist them in the process of family reconciliation, they can impact the end-of-life experience in a positive way.

    hospitals. During the last 25 years, patient involvement and quality improvement have become connected in Danish healthcare policy. However, the ideal of involving patients in quality improvement is described in very general terms and with only few specific expectations of how it is to be carried out...... in practice, as I show in the thesis. In the patient involvement literature, the difficulties of getting patient involvement in quality improvement to have in an impact on the planning and development of healthcare services is, for example, ascribed to conceptual vagueness of patient involvement, differences...... in perspectives, values and understandings between patients and healthcare professionals, or the lack of managerial attention and prioritization....

    The aim of this paper is to present our "Patient Keeper" application, which is a client-server medical application. "Patient Keeper" is designed to run on a mobile phone for the client application and on a PC for the server application using J2ME and JAVA2, respectively. This application can help doctors during visits to their patients in hospitals. The client application allows doctors to store on their mobile phones the results of their diagnoses and findings such as temperature, blood pressure, medications, analysis, etc., and send this information to the server via short message service (SMS) for storage in a database. The server can also respond to any request from the client and send the result via Bluetooth, infrared, or over the air. Experimental results showed a significant improvement of the healthcare delivery and reduction for in-patient stay.

    Kessler, Daniel P; Mylod, Deirdre

    2011-01-01

    This paper aims to investigate how patient satisfaction affects propensity to return, i.e. loyalty. Data from 678 hospitals were matched using three sources. Patient satisfaction data were obtained from Press Ganey Associates, a leading survey firm; process-based quality measures and hospital characteristics (such as ownership and teaching status) and geographic areas were obtained from the Centers for Medicare and Medicaid Services. The frequency with which end-of-life patients return to seek treatment at the same hospital was obtained from the Dartmouth Atlas. The study uses regression analysis to estimate satisfaction's effects on patient loyalty, while holding process-based quality measures and hospital and market characteristics constant. There is a statistically significant link between satisfaction and loyalty. Although satisfaction's effect overall is relatively small, contentment with certain hospitalization experience may be important. The link between satisfaction and loyalty is weaker for high-satisfaction hospitals, consistent with other studies in the marketing literature. RESEARCH LIMITATION/IMPLICATIONS: The US hospitals analyzed are not a random sample; the results are most applicable to large, non-profit teaching hospitals in competitive markets. Satisfaction ratings have business implications for healthcare providers and may be useful as a management tool for private and public purchasers. The paper is the first to show that patient satisfaction affects actual hospital choices in a large sample. Because patient satisfaction ratings are also correlated with other quality measures, the findings suggest a pathway through which individuals naturally gravitate toward higher-quality care.

    Full Text Available Remote patient management (RPM offers renal health care providers and patients with end-stage kidney disease opportunities to embrace home dialysis therapies with greater confidence and the potential to obtain better clinical outcomes. Barriers and evidence required to increase adoption of RPM by the nephrology community need to be clearly defined. Ten health care providers from specialties including nephrology, cardiology, pediatrics, epidemiology, nursing, and health informatics with experience in home dialysis and the use of RPM systems gathered in Vienna, Austria to discuss opportunities for, barriers to, and system requirements of RPM as it applies to the home dialysis patient. Although improved outcomes and cost-effectiveness of RPM have been demonstrated in patients with diabetes mellitus and heart disease, only observational data on RPM have been gathered in patients on dialysis. The current review focused on RPM systems currently in use, on how RPM should be integrated into future care, and on the evidence needed for optimized implementation to improve clinical and economic outcomes. Randomized controlled trials and/or large observational studies could inform the most effective and economical use of RPM in home dialysis. These studies are needed to establish the value of existing and/or future RPM models among patients, policy makers, and health care providers.

    Full Text Available It is not enough to consider treatment and care depression in the oncology that is the most common psychiatric illness in cancer patient affects of cancer treatment and the patient`s quality of life negatively, which is determined through researches in the field. With development of psycho-oncology it has been demonstrated to establish an important link between the cancer patient`s treatment as well as psycho-social support for the patient and psychiatric treatment and care for the if it is needed. With this connection between them it has been proposed to use of bio-psycho-social-model in cancer patient to improve their care. To achieve this goal, it is expected from medical personnel to realize patients psychosocial need und if he/she has a psychiatric disorders or syndromes. For the medical personnel that work in oncology services, it is inevitable to organize in order to raise the awareness of depression in the cancer patients. In the present study, it is focused on raising the awareness of depression in cancer patient for the medical personnel.

  19. Measuring the patient experience.

    2011-01-01

    This paper examines the complex issues of measuring the patient experience and evaluating the quality of health care. It discusses the use of surveys, patient stories and narrative methods of data collection in an attempt to define quality and how it should be measured. A recent Department of Health (DH) document insists that patients will be at the heart of decision making in the NHS by having greater control in informing strategic commissioning decisions (DH 2010c). The government aims to improve patient experience, enabling patients to rate services according to the quality of care they receive. This will be carried out using information generated by patients. This paper discusses the advantages and disadvantages of using surveys in gathering patient satisfaction data. It considers the value of surveys in measuring quality of care and appraises their usefulness in strengthening patients' collective voice. The paper investigates the use of another source of feedback - it examines the design of qualitative data collection methods as a means of gaining feedback from service users in encouraging providers of health care to be more responsive to their needs. Too often, patients are expected to fit the services, rather than services meeting the patients' needs. The most effective way of exploring and representing the patient's experience is by using a mixed-method approach. In other words, an integrated approach with the use of surveys and more narrative methods, such as patient stories, will effectively define quality and how it should be measured, ensuring that the focus is always on what matters most to patients.

    A practice that consistently and continuously measures patient perceptions will be more efficient and effective in its daily operations. With pay-for-performance requirements on the horizon and consumer rating sites already publicizing impressions from physician encounters, a practice needs to know how it is performing through the eyes of the patients. Azalea Orthopedics has used patient feedback to coach its physicians on better patient communication. The Orthopaedic Institute has used patient satisfaction results to reduce wait times and measure the return on investment from its marketing efforts. Patient survey results that are put to work can enhance the efficiency and effectiveness of practice operations as well as position the practice for increased profitability.

Leaning on the work of Hippocrates, Darwin, and William Osler, the authors sketch out the case for honoring patients as indispensable teachers of the art and science of medicine. They argue that this tradition of Hippocratic medicine both anticipates modern precision medicine and reawakens a focus on public health medicine, each a benefit to the patients and communities served by physicians. A community that compromises the learning relationship of physician to patient and population undermines quality of care.

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available In mechanically ventilated patients, assisted mechanical ventilation (MV is employed early, following the acute phase of critical illness, in order to eliminate the detrimental effects of controlled MV, most notably the development of ventilator-induced diaphragmatic dysfunction. Nevertheless, the benefits of assisted MV are often counteracted by the development of patient-ventilator dyssynchrony. Patient-ventilator dyssynchrony occurs when either the initiation and/or termination of mechanical breath is not in time agreement with the initiation and termination of neural inspiration, respectively, or if the magnitude of mechanical assist does not respond to the patient’s respiratory demand. As patient-ventilator dyssynchrony has been associated with several adverse effects and can adversely influence patient outcome, every effort should be made to recognize and correct this occurrence at bedside. To detect patient-ventilator dyssynchronies, the physician should assess patient comfort and carefully inspect the pressure- and flow-time waveforms, available on the ventilator screen of all modern ventilators. Modern ventilators offer several modifiable settings to improve patient-ventilator interaction. New proportional modes of ventilation are also very helpful in improving patient-ventilator interaction.

    National Committee for Quality Assurance recommends patient-centered medical homes incorporate input from patient populations; however, many health care organizations do not. This qualitative study used two open-ended questions from 148 active duty Army Soldiers and their family members to illicit recommendations for primary care providers and clinic leadership that would improve their health care experiences. Content analysis and descriptive statistics were used to analyze responses. Participant responses were related to four major themes: Access to Care, Interpersonal Interaction, Satisfaction of Care, and Quality of Care. Participants were overall satisfied with their care; however, spending less time waiting for appointments and to see the provider or specialist were the most frequently requested improvements related to Access to Care. For Interpersonal Interaction, 82% of the responses recommended that providers be more attentive listeners, courteous, patient, caring, and respectful. Decreasing wait times and improving interpersonal skills would improve health care experiences and patient satisfaction. Reprint & Copyright © 2016 Association of Military Surgeons of the U.S.

    The benefits of ionizing radiation in the diagnosis and treatment of cancer, as well as other conditions such as cardiac ablation, are well established. However determination, monitoring, and evaluation of patient doses is not as easy task. Furthermore, radiation doses for individual patients may vary greatly from one radiological procedure to another. Attention is needed to reduce unnecessary radiation exposure to patients from All types of radiation producing machines and equipment. The patient risk from radiation injury-stochastic and/or deterministic must be weighted against the benefits of a proper medical examination or treatment as well as the risk of depriving the patient from the necessary medical care. Arbitrary reduction of radiological patient doses without regard to final outcome is determined to proper medical care provided to the patient. Sacrificing image quality in order to reduce patient dose is potentially harmful to the patient as well. Furthermore, the role of radiation exposure incurred from screening procedures such as mammography, needs to be properly considered and differentiated from medically indicated procedures. A known radiation induced risk needs to be balanced against diagnostic efficacy of a screening procedure. In these cases, regulations on standards and guidelines for determination, monitoring, and evaluation of patient doses may be appropriate. In this paper, the technical data collected in the United States have been compared with the corresponding data in Canada. However, even here, it has been recognized that we can not assume that one dose limit fits all. It is advisable to consider individual patient specifics if it means the difference between detection and miss

    The objectives of this study were to determine the entrance surface dose to the patient and to estimate the dose to the uterus and ovaries due to hysterosalpingography (HSG) diagnostic examinations performed in Recife-Pe, Brazil. The entrance doses were measured using four thermoluminescent dosimeters per patient, attached to anatomical landmarks on the patient's skin. The study was carried out on 25 patients between 21 and 45 years of age who underwent the HSG examinations in two training hospitals and one private radiodiagnostic institute. The number of exposures performed ranged from 4 to 15 radiographs per patient measured. Entrance surface doses varied between 4.99 and 36.6 mGy, with an average of 12.6mGy. The doses to the ovaries and uterus ranged from 0.80 mGy to 5.8 mGy and 1.10mGy to 8.05 mGy, respectively. (author)

    2016-07-01

    Physiotherapy of cancer patients is one of the most controversial issues in our country. Malignant diseases are firstly mentioned as a contraindication of physiotherapy. Until now, physiotherapy was not suggested (or only in limited accessibility) for those patients who had malignant disease in medical history. International medical practice was less restrictive in managing this topic. The development of imaging techniques put this question in a new light. On the basis of evidence, the majority of articles have reported beneficial effects of physiotherapy in cancer patients, and only few articles mentioned it as harmful. Of course, each patient requires an individual assessment, however, if we exclude the possibility of tumor recurrence and metastasis, most of physiotherapy procedures can be used safely. One of the aims of this review is to support the physicians' decisions when to prescribe treatments, in such a way, that more patients could receive physiotherapy. Orv.

    Patient exposures arising from radiological procedures form the largest part of the population exposure from artificial sources of radiation. According to United Nations Scientific Committee on the Effects of Atomic Radiation, the annual frequency of X ray examinations is 360 per 1000 individuals worldwide. Owing to the associated risk of radiation detriment to the patient, there is a clear need to monitor and control these exposures, and to optimize the design and use of the X ray imaging equipment so that the patient dose is reduced as far as possible, consistent with achieving the required clinical image quality.

  7. Constructions of the patient in healthcare communications: six patient figures.

    Science.gov (United States)

    Pors, Anja Svejgaard

    2016-01-01

    The purpose of this paper is to examine how strategic, patient-centred communication plays a part in the discursive management of expectations posed to patients and healthcare organizations. The paper provides an analysis of four documents collected as part of an ethnographic case study regarding "The Perspective of the Patient" - a Danish Hospital's patient-centred communication programme. Mapping methods inspired by Grounded Theory are used to qualify the analysis. The paper shows that strategic patient-centred communication addresses both a care-oriented approach to the patient and deploys market perceptions of patients. Market and care is seen as co-existing organizing modes that entail expectations to the patient. In the communication programme the patient is constructed in six information-seeking patient figures: affective patient; target group patient; citizen with rights; patient as a competent resource; user as active partner; and consumer. As a result, the patient-centred communication programme renders the patient as a flexible figure able to fit organizational demands of both care orientation and market concerns. This study contributes to qualitative research in organizational health communication by combining two subfields - patient-centredness and health communication - in an empirical study of how market and care are intertwined in a patient-centred communication programme. The argument goes beyond the prevalent prescriptive approaches to patient-centredness and healthcare communication, instead providing a critical analytical perspective on strategic communication and patient-centredness and showing how expectations are posed to both patient and organization.

    Objective: To describe the chest computed tomographic (CT) findings of Legionella pneumophila pneumonia. Methods: CT scans obtained from 23 sporadic cases of L. pneumophila pneumonia were retrospectively reviewed. Chest CT findings were analyzed with regard to the patterns and distributions of pulmonary abnormalities. We also analyzed the histopathology of lungs from guinea pigs with experimentally induced L. pneumophila pneumonia. Results: Consolidation and ground-glass opacity (GGO) were the main findings of CT scans in L. pneumophila pneumonia. The distribution of opacities was categorized as non-segmental (n = 20) and segmental (n = 4). Non-segmental distribution may follow an onset of segmental distribution. Pleural effusion was observed in 14 (58.3%) patients, of which 13 were accompanied with non-segmental distribution. Abscess formation was observed in only one immunocompromised patient. In the animal pneumonia model, the lesions comprised of terminal bronchioles, alveolar spaces, and interstitia. Small bacilli were observed to be contained by many macrophages within the alveoli. Conclusion: Non-segmental distribution was significantly more frequent than segmental distribution in L. pneumophila pneumonia. It is possible that L. pneumophila infection initially results in segmental pneumonia, which progresses to typical non-segmental distribution.

    In this paper, the relation between psychological factors and psychiatric disorders in patients with skin diseases is discussed. On the one hand psychological factors (stress, negative emotions) can influence the generation and aggravation of skin disorders (urticaria, atopic dermatitis, vitiligo), on the other hand psychological disorders can result in some skin diseases (psoriasis, atopic dermatitis). In the majority of cases the quality of life is poorly estimated by patients with skin problems. Psychodermatology is divided into three categories according to the relationship between skin diseases and mental disorders: 1) psychophysiologic disorders caused by skin diseases triggering different emotional states (stress), but not directly combined with mental disorders (psoriasis, eczema); 2) primary psychiatric disorders responsible for self-induced skin disorders (trichotillomania); and 3) secondary psychiatric disorders caused by disfiguring skin (ichthyosis, acne conglobata, vitiligo), which can lead to states of fear, depression or suicidal thoughts.

    It has been suggested that it is very important to position patients reproducibly at different stages of radiotherapy treatment planning and treatment, or similar procedures. Devices have been described for positioning a patient's upper and lower thorax. This invention provides reproducible positioning for a female patient's breasts, for example in planning treatment of and treating breast tumours. The patient is placed prone, using for example an upper thorax device. A support device is placed central to and beneath her breasts to partially displace them outwards. The device may be triangular in section with one apex contacting the chest wall at the sternum. Restraining straps may be provided to hold the breasts against the support device. Means may be provided to take a healthy breast from the path of radiation through the tumour. (author)

  18. Doctors and patients.

    Science.gov (United States)

    Gillon, R

    1986-02-15

    Gillon outlines some prima facie moral duties of physicians to patients that have emerged from his previous articles in a series on philosophical medical ethics. These duties follow from four general ethical principles--respect for autonomy, beneficence, non-maleficence, and justice--plus the self-imposed supererogatory duty of medical beneficence. From these principles the author derives such duties as providing adequate information and advice on treatment options, encouraging patient participation leading to informed decisions, maintaining competence and exposing incompetence, admitting errors, disclosing personal medico-moral standards, and acknowledging that other interests may occasionally supersede those of the individual patient. Gillon concludes that, where self interest conflicts with medical beneficence, the claim of medicine as a profession requires that the patient's interests take priority.

    To measure the frequency of depression and its risk factors in patients under going hemodialysis. It is a cross-sectional prospective study conducted at Hemodialysis unit of Shalamar Hospital and Shaikh Zayed Hospital, Lahore from 1/sup st/ January 2006 to 30/sup th/ April 2006. All patients getting regular hemodialysis for more than three months were included. Beck's Depression Inventory- II (BDI-II; adapted in Urdu) was administered on all the patients who were able to read or understand it. Blood sample were drawn at the same time for routine hematological, biochemical parameters and viral markers (Anti HCV and HbsAg). Diagnosis was made as per Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM IV) for correlation of psychological variables with clinical, hematological and biochemical parameters. Eighty nine patients were enrolled which included fifty two (58.4%) were male and seventy seven (86.5%) were married. Major causes of renal failure were diabetes, hypertension and chronic glomerulonephrotis. Duration of dialysis was from 03 to 49 months with mean of 19.64 +- 11.7 months. Severity of depression was categorized in to mild, moderate and severe on the basis of BDI score. Majority of the patients fifty (56.1%) were moderately to severely depressed and there was no gender difference in the prevalence of depression. Majority of patients undergoing hemodialysis were depressed. Major risk factors for depression were marital status, illiteracy, number of children, socioeconomic factors, gender, hypertension and hypoalbuminemia. Patients with anemia, hyponatremia and hyperkalemia had suicidal tendency. Patients with hepatitis C and disturbed liver function have strong correlation with psychological parameters. (author)

    This study aims to investigate the simultaneous effect of subjective norm, perceived behavioral control and trust on patient loyalty. The empirical data were collected through survey. The respondents of the survey are 157 patients of a health-care service institution in Bogor, Indonesia. Multiple regressions analysis was performed to test the conceptual model and the proposed hypotheses. The findings showed that subjective norm and trust influence patient loyalty positively. However, this research also found that perceived behavioral control does not influence patient loyalty significantly. The survey was only conducted at one health-care service institution in Bogor, Indonesia. In addition, convenience sampling method was used. These conditions may cause that the research results can not be generalized to the other contexts. Therefore, replication research is needed to test the stability of the findings in the other contexts. Health-care service institutions need to pay attention to trust and subjective norm to establish patient loyalty. This study is believed to be the first to develop and test patient loyalty model that includes subjective norm, perceived behavioral control and trust.

    PURPOSE We aimed to develop a simple standardized clinical score to stratify emergency ward patients with clinically suspected PE into groups with a high, intermediate, or low probability of PE, in order to improve and simplify the diagnostic approach. METHODS Analysis of a database of 1090 consecutive patients admitted to the emergency ward for suspected PE, in whom diagnosis of PE was ruled in or out by a standard diagnostic algorithm. Logistic regression was used to predict clinical parameters associated with PE. RESULTS 296 out of 1090 patients (27%) were found to have PE. The optimal estimate of clinical probability was based on eight variables: recent surgery, previous thromboembolic event, older age, hypocapnia, hypoxemia, tachycardia, band atelectasis or elevation of a hemidiaphragm on chest X-ray. A probability score was calculated by adding points assigned to these variables. A cut-off score of 4 best identified patients with low probability of PE. 486 patients (49%) had a low clinical probability of PE (score 9). CONCLUSION This clinical score, based on easily available and objective variables, provides a standardized assessment of the clinical probability of PE. Applying this score to emergency ward patients suspected of PE could allow a more efficient diagnostic process.

    To investigate the baseline status of patients' awareness, knowledge, and attitudes to patient safety in China, and to determine the factors that influence patients' involvement in patient safety. We conducted a cross sectional survey using questionnaires adapted from recent studies on patient safety from outside China. The items included medical errors, infection, medication safety, and other aspects of patient safety. The questionnaire included 17 items and 5 domains. The survey was conducted between Jan. 2009 and Dec. 2010 involving 1000 patients from ten grade-A hospitals in seven provinces or cities in China. Most patients from the surgery departments completed the questionnaires voluntarily and anonymously. Five reviewers independently input the data into Microsoft Excel 2003, and the data were double-checked. Data were analyzed using SPSS 15.0 software for differences in the perceptions and attitudes of patients toward patient safety among different genders, ages, and regions. We distributed 1000 questionnaires and collected 959 completed questionnaires (response rate: 96%). Among the respondents, 58% of patients did not know what medical error is. Sixty-five percent of patients wanted disclosure of all medical errors. After errors occurred, 58% of patients wanted explanations of all possible harms that had resulted. Among 187 patients who had experienced medical errors, 83% of patients had sought appropriate legal action. About 52% of patients understood hospital infection, but 28% patients did not know that infections could occur in hospital. Seventy-eight percent of patients thought that medical staff should wash their hands before examining patients. More than half of the patients (68%) were willing to remind the staff of hygiene if they saw unsanitary conditions in a health clinic. Only 14% of patients knew the side effects of medications that they took. The majority of patients surveyed expressed willingness to contribute to patient safety, but their

    2016-11-01

    In a context of regular review of transfusion practice, the aim of this review is to present an update of the scientific basis of the so-called "patient blood management" (PBM), the state of its development in Europe, and possible ways to progress its development further in France. Analysis and synthesis of the data from scientific literature on the scientific basis of PBM (methods, indications, efficacy, risks, efficiency). PBM appears as an evidence-based, patient centred, multidisciplinary approach, aiming to optimise the care of patients who might need transfusion and, consequently, the use of blood products. PBM is based on three pillars: optimise the patient's own blood supplies, minimise blood loss, optimise patient's tolerance of anaemia. Available scientific evidence can be considered as sufficient to consider PBM guidelines and practices as an indispensable complement to the transfusion medicine guidelines and practices. Several countries have launched PBM programmes (alternatives to allogeneic transfusion and optimisation of the use of blood components). Although current French national transfusion guidelines contain some PBM measures, PBM programmes should be further developed in France, primarily for medical reasons. Possible ways, using the existing basis having proved to be effective, are proposed to further develop PBM in France, as a complement to transfusion medicine, with the participation of involved stakeholders, including experts from relevant medical specialties, both at local and national levels.

    To elicit patient stakeholders' experience and perspectives about patient-centred care. Qualitative. A large urban healthcare system. Four patient stakeholders who are prostate cancer survivors. Experience and perspectives of patient stakeholders regarding patient-centred care and treatment decisions. Our patient stakeholders represented a diverse socio-demographic group. The patient stakeholders identified engagement and dialogue with physicians as crucial elements of patient-centred care model. The degree of patient-centred care was observed to be dependent on the situations. High severity conditions warranted a higher level of patient involvement, compared to mild conditions. They agreed that patient-centred care should not mean that patients can demand inappropriate treatments. An important attribute of patient-centred outcomes research model is the involvement of stakeholders. However, we have limited knowledge about the experience of patient stakeholders in patient-centred outcomes research. Our study indicates that patient stakeholders offer a unique perspective as researchers and policy-makers aim to precisely define patient-centred research and care.

    Full Text Available Humanoids have increasingly become the focus of attention in robotics research in recent years, especially in service and personal assistance robotics. This paper presents the application developed for humanoid robots in the therapy of dementia patients as a cognitive stimulation tool. The behaviour of the robot during the therapy sessions is visually programmed in a session script that allows music to play, physical movements (dancing, exercises, etc., speech synthesis and interaction with the human monitor. The application includes the control software on board the robot and some tools like the visual script generator or a monitor to supervise the robot behaviour during the sessions. The robot application's impact on the patient's health has been studied. Experiments with real patients have been performed in collaboration with a centre of research in neurodegenerative diseases. Initial results show a slight or mild improvement in neuropsychiatric symptoms over other traditional therapy methods.

    The risk associated with receiving health care has called for an increased focus on the role of patients in helping to improve safety. Recent research has highlighted that patient involvement in patient safety practices may be influenced by patient perceptions of patient safety practices and the perceptions of their health care providers. The objective of this research was to describe patient involvement in patient safety practices by exploring patient and nursing staff perceptions of safety. Qualitative focus groups were conducted with a convenience sample of nursing staff and patients who had previously completed a patient safety survey in 2 tertiary hospital sites in Eastern Canada. Six focus groups (June 2011 to January 2012) were conducted and analyzed using inductive thematic analysis. Four themes were identified: (1) wanting control, (2) feeling connected, (3) encountering roadblocks, and (4) sharing responsibility for safety. Both patient and nursing staff participants highlighted the importance of building a personal connection as a precursor to ensuring that patients are involved in their care and safety. However, perceptions of provider stress and nursing staff workload often reduced the ability of the nursing staff and patient participants to connect with one another and promote involvement. Current strategies aimed at increasing patient awareness of patient safety may not be enough. The findings suggest that providing the context for interaction to occur between nursing staff and patients as well as targeted interventions aimed at increasing patient control may be needed to ensure patient involvement in patient safety.

In many developing countries, teleophthalmology is being utilized to provide quality eye care to the underserved urban population and the unserved remote rural population. Over the years, technological innovations have led to improvement in evidence and teleophthalmology has evolved from a research tool to a clinical tool. The majority of the current teleophthalmology services concentrate on patient screening and appropriate referral to experts. Specialty care using teleophthalmology services for the pediatric group includes screening as well as providing timely care for retinopathy of prematurity (ROP. Among geriatric eye diseases, specialty teleophthalmology care is focused toward screening and referral for diabetic retinopathy (DR, glaucoma, age-related macular degeneration (ARMD, and other sight-threatening conditions. Comprehensive vision screening and refractive error services are generally covered as part of most of the teleophthalmology methods. Over the past decades, outcome assessment of health care system includes patients’ assessments on their health, care, and services they receive. Outcomes, by and large, remain the ultimate validators of the effectiveness and quality of medical care. Teleophthalmology produces the same desired clinical outcome as the traditional system. Remote portals allow specialists to provide care over a larger region, thereby improving health outcomes and increasing accessibility of specialty care to a larger population. A high satisfaction level and acceptance is reported in the majority of the studies because of increased accessibility and reduced traveling cost and time

    A patient support system for use in computerized tomography (CT) is described. The system is particularly useful for CT scanning of the brain and also of the abdominal area. The support system consists of two moveable tables which may be translated into position for X-ray scanning of the patient's body and which may be translated incrementally and automatically to obtain scans at adjacent locations. For use with brain scans, the second table is replaced by a detachable restraint assembly which is described in detail. The support system is so designed that only a small volume of low density material will intercept the X-ray beam. (UK)

    Full Text Available Psoralen compounds such as methoxsalen are photosensitizer agents used in conjunction with ultraviolet A (UVA radiation exposure as photochemotherapy (Psoralens and ultraviolet-A therapy [PUVA therapy] for certain epidermal skin disorders such as psoriasis and vitiligo. Methoxsalen has been shown to be associated with premature cataract formation by forming adducts with lens proteins following oral administration and subsequent UVA exposure. Hence, the use of UV-filtering glasses is recommended during PUVA therapy sessions. Ocular tissues can be exposed to its photosensitizing effect with subsequent UV radiation exposure through sunlight if the patient was to be without protective eye glasses, potentially causing macular toxicity. Till date, there have been no reports in the literature of any posterior segment ocular toxicity arising from methoxsalen use. Here, we describe a case of a bilateral macular toxicity in a middle-aged male treated with methoxsalen for vitiligo.

    Full Text Available Background. Diabetes mellitus (DM confers high vascular risk and is a growing national epidemic. We assessed clinical characteristics and prevalence of diagnosed DM among patients hospitalized with acute myocardial infarction (AMI in the US over the last decade. Methods. Data were obtained from all states within the US that contributed to the Nationwide Inpatient Sample. All patients admitted to hospitals between 1997 and 2006 with a primary discharge diagnosis of AMI were included. Time trends in the proportion of these patients with DM diagnosis were computed. Results. The portion of patients with comorbid diabetes among AMI hospitalizations increased substantially from 18% in 1997 to 30% in 2006 (<.0001. Absolute numbers of AMI hospitalizations in the US decreased 8% (from 729, 412 to 672, 243, while absolute numbers of AMI hospitalizations with coexisting DM rose 51% ((131, 189 to 198, 044, both (<.0001. Women with AMI were significantly more likely to have DM than similarly aged men, but these differences diminished with increasing age. Conclusion. Although overall hospitalizations for AMI in the US diminished over the last decade, prevalence of diabetes rose substantially. This may have important consequences for the future societal vascular disease burden.

    Schizophrenia is a maldevelopmental disorder of the brain that manifests in positive, negative, cognitive and affective symptoms. Currently, the mainstay of treatment involves pharmacotherapy. The limitations of antipsychotic treatment are that they can only control symptoms and cannot cure the illness, and 20% of patients do not respond, thus leading to the requirement of maintenance treatment. Patients that do respond continue to have disabling residual symptoms such as amotivation and isolation, maladaptive behavior, and impaired social functioning. These symptoms prevent patients from attaining educational, occupational, and social roles. Psychosocial interventions and models of quality of life in schizophrenia are based on the notion that increases in psychosocial functioning will be related to improvement in subjective experiences, such as self-esteem and satisfaction with life. The comparative effect of specific treatment methods and the additional benefits of multiple treatments need to be explored. Diversified techniques have also been employed, such as shaping, cognitive process therapy, mastery-oriented skill training, motivation and enhancement. Issues in designing psychosocial interventions and the role of various professionals in providing such interventions need to be carefully considered. Predictor variables and the indications for particular therapies in an individual need to be explored. Generalizability of the gains made by rehabilitation/recovery is also an important consideration. Patients in jail, chronic mental hospitals, private facilities, and the Veterans Administration system are all different in their ability to benefit, their motivations, and the severity of their psychopathology. Therefore, it is very difficult to generalize findings from one setting to another.

    If the "old economy" preached standardization of products/services in order to reduce costs, the "new economy" is based on the recognition of the needs and the management of information. It is aimed at providing better and more usable services. One scenario is a national health service with regional management but based on competition between hospitals/companies.This led to a different handling of the user/patient, which has become the center of the health system: marketing seeks to retain the patient, trying to push a client-patient to not change their healthcare service provider. In costs terms, it is more economical to retain a customer rather than acquire a new one: a satisfied customer is also the best sounding board for each company. Customer equity is the management of relations with patients which can result in a greater customer value: it is possible to recognize an equity of the value, of the brand and of the report. Loyalty uses various marketing activities (basic, responsive, responsible, proactive and collaborative): each hospital/company chooses different actions depending on how many resources it plans to invest in loyalty.

    Full Text Available Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL is a hereditary neurological disease accompanied by recurrent ischemic events, characterized by the presence of psychiatric disorders. The aim of this study was to examine the occurrence of depression and its severity among patients with CADASIL. Sixteen patients with diffuse white matter changes on MRI and clinical signs suggesting CADASIL were included in the study. Definitive diagnosis of CADASIL was obtained by electron microscopic analysis of skin biopsies. Testing of the patients’ affective status was primarily devoted to detecting depression. Electron microscopic examinations of all skin biopsies revealed numerous granular osmiophilic material (GOM deposits embedded into the basal lamina around altered or degenerated vascular smooth muscle cells (VSMCs. Clinical symptoms of depression were present in a great number of examined CADASIL patients. The frequency of depression was higher than previously reported. Psychiatric disturbances might also represent the onset of CADASIL, especially in young patients, and should be evaluated by differential diagnosis.

    Individuals have different values. They seek to express their individuality even when receiving medical care. It is a part of modern medical practice and respect for patient autonomy to show respect for different values. We give an account of what it means to respect different values and challenging patients in medical practice. Challenging choices are often choices which are perceived by many to be either irrational or against a person's interests, such as engaging in harmful or excessively risky activities. When the medical profession is involved in such choices, the basic medical principle of acting in a person's best interests is challenged. Often doctors refuse to respect controversial choices on paternalistic grounds. We should all respect and facilitate the controversial choices of competent individuals, subject to resource limitations, our own and others well-being and autonomy, and the public interest. But more importantly, sometimes such choices make for a better, more autonomous life. Sometimes, such choices reflect considerations of global well-being or altruism, or idiosyncratic attitudes to risk. Sometimes, they reflect unusual values. However, in some other cases, controversial choices are irrational and are not expressions of our autonomy. Doctors should assist patients to make rational if individual choices. The patient also bears the responsibility for bringing his beliefs to the attention of the clinician.
