BACKGROUND: Several therapeutic options are available for the treatment of vitiligo. Concern exists that there is no uniform approach towards the management of vitiligo among Dutch dermatologists. METHODS: A written survey concerning the management of vitiligo was sent to 332 dermatologists in The Netherlands. RESULTS: The response rate was 86%. "Giving information and reassurance concerning the nature of disease" was regarded by most dermatologists (68%) as being the most important goal in the management of vitiligo. Only 16% of the dermatologists aimed for active treatment in vitiligo. The reported therapy choices in children resembled those of adults, except that slightly more dermatologists did not prescribe active therapy in children. Nine different therapeutic modalities were mentioned as first choice therapies. Topical corticosteroids were indicated by most dermatologists as first choice therapy (241 out of 266, i.e. 91%); however, only 2% indicated that 50% or more of the patients achieved a successful treatment; 66% found that less than 25% of the patients were successfully treated with topical corticosteroids. Only 15% of the respondents reported that 50% or more of the patients were treated successfully with narrow-band UVB. The observed response profile to broad-band UVB therapy was found to be comparable with that of narrow-band UVB. The classical therapy with oral psoralen plus UVA (PUVA) was prescribed as first choice therapy by only 12% (32 out of 266) of the dermatologists. Only 6% of these respondents observed that 50% or more of the patients achieved successful therapy using oral PUVA. The recommended maximum treatment duration for topical corticosteroids, oral PUVA, and UVB therapy was found to vary from 3 to 12 months. CONCLUSIONS: Most dermatologists in The Netherlands do not offer active treatment in vitiligo, probably because the estimated effectiveness of (nonsurgical) repigmentation therapy is low. In cases where treatment is prescribed, there appears to be no consensus on the choice of therapies and treatment strategies. The development of practice guidelines may be helpful in reducing inappropriate care and improving treatment outcome. 相似文献

So far there is no uniformity in the evaluation methods used in the assessment of treatment outcome in vitiligo studies. The ability to objectively measure surfaces of vitiligo lesions is important for both clinical practice and research. Our objective was to assess the reproducibility, accuracy, user-friendliness and time effectiveness of a new digital image analysis system for surface measurement of vitiligo lesions. Three different observers performed both a visual estimation and a digital image analysis on 30 images of 10 vitiligo lesions. Inter- and intra-observer variation were evaluated and results were compared with the 2D gold standard measurements and a 3D measurement. A high inter- and intra-observer variability was observed for the visual estimation of surfaces. With the digital image analysis system a significant improvement of the reproducibility was achieved (p = 0.01). Moreover, results were accurate and the measurement procedure was user-friendly. Importantly, a systematic underestimation was demonstrated when comparing the 2D with the 3D measurements. We introduced an objective measurement method that might be useful in the future for consistently measuring surfaces of selected vitiligo lesions both before and after different therapeutic modalities. 相似文献

Background Non‐cultured cellular grafting as a surgical procedure is indicated to treat stable vitiligo, refractory to medical treatment, and is gaining wider acceptance among dermatologists. Objective The aim of this study was to assess the efficacy of non‐cultured melanocyte‐keratinocyte transplantation (MKT) for the treatment of generalized vitiligo in Iranian patients. Methods In this clinical trial, a total of 14 vitiligo patches in eight patients were treated; eight patches with non‐cultured MKT and six patches dermabraded alone without application of keratinocyte‐melanocyte suspension. Repigmentation was compared at about 4 months post‐transplantation. Results Of the eight lesions treated with non‐cultured MKT, four lesions showed 96–100% repigmentation, one lesion 65–95% and three lesions 0–25%. Of the patients who showed excellent results, only one showed a post‐inflammatory hyperpigmentation in recipient and control areas. Of the six control lesions, five showed failed repigmentation and one showed post‐inflammatory hyperpigmentation. Conclusion Non‐cultured MKT is an effective method to treat stable vitiligo. Studies on larger series of vitiligo patients are required to confirm its efficacy. 相似文献

Background There are concerns that there is no uniform approach towards the management of vitiligo.
Objectives To explore attitudes and strategies for the management of vitiligo among dermatologists.
Methods A self-administered questionnaire containing 22 questions was distributed to 160 dermatologists attending a national dermatology conference in 2007.
Results One hundred and twelve dermatologists responded to the questionnaire (70% response rate). We had 105 completed questionnaires (seven were excluded due to incompleteness). Active treatment of vitiligo was recommended by 96% in more than half of patients, while 79% recommended treatment at non-visible sites. Repigmentation was regarded as main treatment goal by 54%. Mid-potent topical steroids were widely prescribed for focal vitiligo (72% in children and 65% in adults). Use of tacrolimus and pimecrolimus was limited. The most common used phototherapy was 'narrowband ultraviolet B' (NBUVB; 36% and 40% for generaliased vitiligo in children and adults, respectively). The use of oral psoralen plus UVA (PUVA) was limited (8% for generalized vitiligo in adults). Few respondents (1–8% for different types of vitiligo) prescribed outdoor topical PUVA. Vitiligo surgery was advised mainly for segmental type (18% in adults and 5% in children). Depigmentation was the first option for universal vitiligo by 50% and 30% in adults and children, respectively.
Conclusions Most dermatologists are enthusiastic about active treatment of vitiligo even in hidden sites. Overall, the most two common treatment modalities were topical steroids and NBUVB. Vitiligo surgery is underutilized. Development of national practice guidelines is needed. 相似文献

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. 相似文献

Background Unstable vitiligo lesions are usually considered to be contraindications for surgical treatment. Unfortunately, in the majority of common vitiligo cases, neither accurate clinical signs nor routine blood tests are available to determine whether or not the disease is active. Objectives To establish a direct correlation between the clinical aspect of vitiligo lesions and their activity. Methods This was a prospective observational study that took place over 1 year. For each patient, a standardized evaluation included both a careful daylight and Wood’s lamp examination, pictures, biopsies performed at the marginal area and histological and immunohistological studies. A second examination to assess the activity of the lesions correctly was performed 1 year after inclusion in the study. Both the clinical changes and the histological features of the lesions in actively spreading vitiligo were compared with those in stable vitiligo. Results This study included 50 patients. The lesions were classified as hypomelanotic with poorly defined borders (HPDB, 29 cases) or amelanotic with sharply demarcated borders (ASDB, 21 cases). One year after the biopsy, of the 48 patients still in the study, 20 had lesions that were considered to be stable and 28 had active lesions. Correlations were successfully obtained between clinical aspects, histological findings and vitiligo activity. The HPDB and ASDB lesions were correlated respectively with active and stable status (P < 0·001). Conclusions A simple clinical examination including a Wood’s lamp examination may allow reliable and efficient evaluation of the stability of vitiligo lesions. 相似文献

Hidradenitis suppurativa (HS) is a long-lasting skin disease with flares of painful boils in areas where skin meets skin, such as the armpits and groins. It affects somewhere between 1 and 40 people out of 1000 worldwide. When trying to measure the effect of a treatment in a clinical trial, so-called ‘outcome measurement instruments’ are used. These are ways of estimating ‘how much’ disease is present. It is obviously important that outcome measurement instruments measure the right thing and do not vary at random. It has previously been shown that outcome measurement instruments used in HS trials lack proof of their reliability. This study therefore aimed to find out how consistently 12 HS-experienced dermatologists would score 24 patients with HS, using nine different instruments. The study showed that one called Hurley staging was an acceptable instrument in terms of consistency of scores. However, Hurley staging is suited only for severity staging e.g. to guide the most appropriate treatment in each stage. For instruments designed to measure changes in disease severity, low agreement between the rating dermatologists was found. Therefore, the results question whether HS physical signs are best measured by traditional instruments based on a physician counting individual HS lesions (affected patches). As a result, other assessment methods of physical signs in HS, using technology such as ultrasound, should also be considered. 相似文献

This detailed and user‐friendly guideline for the diagnosis and management of vitiligo in children and adults aims to give high quality clinical advice, based on the best available evidence and expert consensus, taking into account patient choice and clinical expertise. The guideline was devised by a structured process and is intended for use by dermatologists and as a resource for interested parties including patients. Recommendations and levels of evidence have been graded according to the method developed by the Scottish Inter‐Collegiate Guidelines Network. Where evidence was lacking, research recommendations were made. The types of vitiligo, process of diagnosis in primary and secondary care, and investigation of vitiligo were assessed. Treatments considered include offering no treatment other than camouflage cosmetics and sunscreens, the use of topical potent or highly potent corticosteroids, of vitamin D analogues, and of topical calcineurin inhibitors, and depigmentation with p‐(benzyloxy)phenol. The use of systemic treatment, e.g. corticosteroids, ciclosporin and other immunosuppressive agents was analyzed. Phototherapy was considered, including narrowband ultraviolet B (UVB), psoralen with ultraviolet A (UVA), and khellin with UVA or UVB, along with combinations of topical preparations and various forms of UV. Surgical treatments that were assessed include full‐thickness and split skin grafting, mini (punch) grafts, autologous epidermal cell suspensions, and autologous skin equivalents. The effectiveness of cognitive therapy and psychological treatments was considered. Therapeutic algorithms using grades of recommendation and levels of evidence have been produced for children and for adults with vitiligo. 相似文献

Summary Background Relevant and reliable outcomes play a crucial role in the correct interpretation and comparison of the results of clinical trials. There is a lack of consensus around methods of assessment and outcome measures for vitiligo, which makes it difficult to compare results of randomized controlled trials (RCTs) and perform meta-analysis. Objectives To describe the heterogeneity in outcome measures used in published RCTs of vitiligo treatments, and to report the most desirable outcomes from patients' and clinicians' perspectives. Methods We conducted a systematic review of outcome measures used in RCTs as well as a survey of the most desirable outcomes identified by patients and clinicians as part of a Vitiligo Priority Setting Partnership. Results Outcomes from 54 eligible trials were analysed and compared with outcomes suggested by patients and clinicians. In the systematic review, 25 different outcomes were reported. Only 22% of trials had clearly stated primary outcome measures. Repigmentation was the most frequently reported outcome in 96% of trials and was measured using 48 different scales. Only 9% of trials assessed quality of life. Thirteen per cent measured cessation of spreading of the disease and 17% of studies reported patients' opinions and satisfaction with the treatment. In contrast, out of 438 suggestions made by patients and clinicians, cosmetically acceptable repigmentation (rather than percentage of repigmentation) was the most desirable outcome (68%), followed by cessation of spread of vitiligo (15%), quality of life (8%) and maintenance of repigmentation (4%). Conclusions We propose that future vitiligo trials should include repigmentation, cosmetic acceptability of results, global assessment of the disease, quality of life, maintenance of repigmentation, stabilization of vitiligo and side-effects. International consensus among clinicians, researchers and patients is needed to establish an agreed core outcome set for future vitiligo trials. 相似文献

BACKGROUND: In vitiligo and piebaldism the lack of melanin in the epidermis is due to the fact that melanocytes are missing. The patients suffer psychologically and the white areas have lost the part of the skin barrier protection normally provided by the melanocytes. Medical treatments are ineffective in many of the patients, and surgical methods have therefore been developed. OBJECTIVES: It is important to investigate the long-term results and factors that might influence the outcome of melanocyte transplantations in order to form a basis for guidance in the selection of patients who will benefit most from the treatments. METHODS: A follow-up of 132 patients who had been treated by transplantation on 176 occasions in total, 1-7 years previously, was carried out by questionnaires and clinical examinations. We investigated the responses in five types of leucoderma to three different transplantation methods: autologous cultured melanocytes, ultrathin epidermal sheets and basal layer cell suspension. RESULTS: Stable types of leucoderma, i.e. segmental vitiligo and piebaldism, responded in most cases with 100% repigmentation, regardless of the surgical method used. For these types of leucoderma surgery seems to be the method of choice. The largest group, vitiligo vulgaris, was thoroughly scrutinized and three statistical models were used to analyse the data. The ultrathin epidermal sheet method gave somewhat better overall results, but was the method that gave the worst outcome in knee and elbow areas, emphasizing the importance of the right choice of method depending on the anatomical location to be treated. Irrespective of the method, fingers and elbows were the most difficult areas to repigment. The trunk and the arms and legs (not including elbows and knees) responded best. Patients with increasing and/or extensive vitiligo vulgaris more often showed incomplete repigmentation. They also had a lower chance of retaining their repigmentation compared with those with less extensive vitiligo. Patients in whom untreated white lesions had increased in recent years tended to respond less well to transplantation compared with patients with unchanged or decreased lesions. Within the vitiligo vulgaris group, patients with short disease duration or with small total vitiligo area responded best to transplantation. The subgroup of vitiligo vulgaris patients with hypothyroidism tend to respond less well to the transplantation and they were generally older at vitiligo onset. This information is of great importance for the selection of patients and when informing about the chances of improvement after transplantation. Slight hyperpigmentation was common, especially when ultrathin epidermal sheets had been used. No scars or indurations were seen in treated areas. CONCLUSIONS: Transplantations are the methods of choice in stable types of leucoderma. Progressive, widespread vitiligo vulgaris should never be selected for transplantation. 相似文献

The accurate measurement of vitiligo surface area is fundamental to the evaluation of treatment efficacy. Digital photography, planimetry and clinical evaluation by the clinician have been used for assessment. Although digital photography with computerized planimetry is a reliable and accurate method, it is labour intensive and expensive. The aim of this study was to evaluate the accuracy and reliability of the point counting method and to compare it with digital planimetry techniques for the estimation of vitiligo surface area. Surface areas of 31 vitiligo lesions of five volunteers were estimated using the point counting and digital planimetry methods. Three independent observers evaluated the outlined areas twice using the point counting technique with an interval of 2 weeks. The same lesions were also measured by one observer applying digital planimetry. The estimation results of three observers were compared using inter and intra-observer correlation analysis test. There was significant inter- and intra-observer agreement for all measurements. There was also significant coincidence between each observer's estimation of the point counting and digital planimetry method. No significant differences on the results of surface area obtained using the two methods were found (p > 0.05). The point counting method may be used as a direct and reliable technique to measure the vitiligo surface area. 相似文献

OBJECTIVE: To assess current practices of US dermatologists regarding the diagnosis, treatment, and management of melanoma in situ (MIS). DESIGN: Survey. PARTICIPANTS: A total of 1200 dermatologists randomly selected from the American Board of Medical Specialists Directory of Board Certified Medical Specialists. MAIN OUTCOME MEASURES: Results based on 597 questionnaires returned. RESULTS: The overall response rate was 63% (597 of 945 eligible participants). To aid in clinical assessment, respondents reported using a magnifying lens (57.4%) and dermoscopy (17.4%). Most dermatologists preferred excisional and saucerization biopsies as the method of choice for sampling. A large percentage of physicians (78.9%) preferentially used dermatopathologists for the evaluation of the majority of pigmented lesions. Although most respondents would not unquestioningly accept a benign pathology diagnosis when there was a clinical suspicion of MIS, 16.1% would accept a pathologist's diagnosis without further action. There was no consensus on the appropriate surgical margins or depth of excision for MIS. Of the respondents who characterized MIS as premalignant and malignant, 63.2% and 46.4%, respectively, did not know what percentage of MISs would progress to metastatic disease if left untreated. CONCLUSIONS: Considerable variability exists in the clinical concept and management of MIS. Dermoscopy is underutilized. The true nature of the evolution of MIS is unknown. Surgical margins and depth of excision need to be standardized to help dermatologists manage disease. Further research in the specific area of MIS is warranted to develop clear guidelines in the management and prevention of further disease. 相似文献

OBJECTIVE: To develop and introduce evidence-based guidelines for the treatment of vitiligo in children and in adults. PATIENTS AND SETTING: Patients, residents, and dermatologists from the Department of Dermatology, Academic Medical Center, University of Amsterdam, and the Netherlands Institute for Pigmentary Disorders in Amsterdam. DESIGN: Scientific evidence obtained from 3 systematic reviews of the literature was combined with the results of 2 questionnaires and interviews of potential users of the guidelines, 3 internal expert meetings, and 1 local expert meeting, during which preliminary guidelines were presented and commented on. A final version of the guidelines was synthesized and disseminated among potential users. Six months after the introduction of these guidelines, their use was evaluated. RESULTS: Before the development of the guidelines, there was no uniformity in treatment selection, and there was a variability in estimates of treatment outcome. The metaanalysis showed class 3 corticosteroids and narrowband UV-B to be the most effective and safest therapies for localized and for generalized vitiligo, respectively. From another systematic review, it could be concluded that patients with segmental, stable, or lip-tip vitiligo could be successfully treated with most autologous transplantation methods. For vitiligo universalis, results of the systematic review showed that depigmentation using monobenzone or a Q-switched ruby laser was equally effective. The final version of the guidelines consisted of a treatment scheme together with detailed treatment protocols. Implementation of the guidelines was evaluated in 5 physicians. After the introduction of these guidelines, they were followed in most adult cases with vitiligo (71% of patients with localized vitiligo, 82% with generalized vitiligo, 100% with stable or segmental vitiligo, and 80% with universal vitiligo). In children with vitiligo, the physicians adhered to the guidelines for 52% of the cases. CONCLUSIONS: Guidelines for the treatment of vitiligo can be successfully developed and disseminated for daily clinical practice. The results of the implementation of these guidelines should be confirmed in other centers involving more clinicians. 相似文献

Vitiligo is a common, acquired pigmentary disorder of unknown etiology with great impact on patient’s appearance and quality of life. It presents a therapeutic challenge to many dermatologists. Photochemotherapy using psoralen and ultraviolet A (UVA) therapy, topical and oral immunosuppresants, as well as cosmetic camouflage are also commonly employed with varying clinical efficacy. Phototherapy is a popular treatment option, which includes both of the generalized ultraviolet B (UVB) therapies, broadband UVB and narrowband UVB (NB-UVB). It has been used favorably, both alone as well as in combination with other agents like topical calcineurin inhibitors, vitamin-D analogs. Combination therapies are useful and may provide quicker regimentation and treat vitiligo with an additive mechanism of action than UVB phototherapy. Advances in technology may lead to the continuing use of UVB phototherapy as a treatment for vitiligo through the development of sophisticated devices and delivery systems as well as innovative application methods. These will provide increased therapeutic options for all vitiligo patients, particularly those with refractory disease. In this article, I have reviewed the available data pertaining to efficacy and safety issues for NB-UVB as monotherapy, its comparison with psoralen plus UVA and other modes of phototherapy, combination regimens that have been tried and future prospects of NB-UVB in vitiligo. 相似文献

In order to develop and test a treatment, researchers measure an ‘outcome’. For example the ‘outcome’ might include a measure of how fast a white patch gets its color back (repigmentation) in vitiligo. Vitiligo is a skin condition, which causes white patches of the skin and sometimes hair. Currently, there is no cure nor firm clinical recommendations for the treatment of vitiligo. One of the main reasons behind this is that different studies measure different outcomes; therefore the studies can't be combined and compared. Recently, the International INitiative for Outcomes for vitiligo (INFO for vitiligo), which includes patients, their caregivers, medical journal editors and doctors from over 24 countries worldwide, have come to an agreement over a set of outcomes for vitiligo, which should be measured in every trial: repigmentation of skin lesions, side effects/harms of treatment and how long the colour stays after repigmentation of vitiligo lesions has occurred. Still, there was no agreement amongst patients and clinicians on which scale (outcome measure) should be used to measure repigmentation. This means that even if all the future trials measure repigmentation, but use different scales to do so, study results still can't be combined and compared. This international study was conducted with an aim to define successful repigmentation from patients’ point of view and propose how and when repigmentation should be evaluated in clinical trials in vitiligo. The authors conducted 3 workshops with vitiligo patients and their parents/care givers in the U.S.A. 73 participants were recruited. “Successful repigmentation” from patients’ perspective means achieving over 80% of repigmentation in a vitiligo patch. Both percentage of repigmentation quartiles (0-25%, 26-50%, 51-79%, 80-100%) and cosmetic acceptability of the results from patients’ point of view, should be measured in every trial. In conclusion, this was the largest patients’ outcomes workshop. Unity among the researchers on using the same scales to measure repigmentation in future trials will bring richer data and therefore clearer clinical recommendations. 相似文献

As vitiligo does not cause any physical impairment, it is often considered unimportant by physicians. Vitiligo patients repeatedly experience disinterest from the medical world regarding their skin problem. A questionnaire survey was used to assess the management of vitiligo patients and the attitude of dermatologists towards vitiligo in Belgium. Vitiligo patients (n = 244) visiting an academic affiliated dermatology department were included and 454 out of 558 Belgian dermatologists returned a mailed questionnaire. Vitiligo patients do not often visit a doctor concerning their disease and do not often treat their disease. Disease severity as reported by the patient is correlated with the number of doctor visits (p = 0.001) but not to treatment of the disease. Information about the treatment and physician's encouragement to treat seem important in motivating patients to treat their vitiligo, but 50% of the patients were not adequately informed about their disease and its treatment during their first doctor visit. Today, nearly all the dermatologists report widely informing their patients, but only 36% of them encourage their patients to treat their disease, being pessimistic concerning expected treatment results. Interestingly, two thirds of the patients who ever treated their disease find it worthwhile. 相似文献

OBJECTIVE: To compare differences in biopsy techniques of actinic keratoses between dermatologists and plastic surgeons. DESIGN: Blinded, comparative, retrospective study. SETTING: Dermatopathology laboratory at a major academic medical center with referral of outside cases.Intervention We reexamined the histopathologic slides of 405 actinic keratosis biopsy specimens obtained by plastic surgeons and dermatologists from January 1, 1992, through May 31, 2002. We were specifically interested in the type of biopsy technique (shave, punch, or excisional biopsy) used for the surgical management of actinic keratoses by both groups of physicians. We also recorded the clinical diagnoses rendered on the dermatopathology request form and compared them with the histopathologic diagnoses. RESULTS: Excisional biopsies were performed by plastic surgeons in 50.0% of the cases, compared with only 1.4% by dermatologists. In contrast, shave biopsies of actinic keratoses were performed by plastic surgeons in only 32.4% of the cases, compared with 89.4% by dermatologists. Only 1 (0.5%) of the 198 dermatopathology request forms submitted by the plastic surgeons mentioned actinic keratosis, compared with 82 (39.6%) of 207 histopathologic evaluation requests submitted by dermatologists. CONCLUSIONS: The predominance of excisional biopsies of actinic keratoses by plastic surgeons may be related to a different ability in the clinical recognition of actinic keratoses compared with that of dermatologists. The surgical approach of dermatologists to shave diagnostically uncertain cutaneous lesions is less invasive than that of plastic surgeons and is more likely to achieve a better cosmetic outcome. 相似文献
