Improvement Across Dimensions of Disease with Lebrikizumab Use in Atopic Dermatitis: Two Phase 3, Randomized, Double-Blind, Placebo-Controlled Monotherapy Trials (ADvocate1 and ADvocate2).

INTRODUCTION: Atopic dermatitis is a complex, chronic, inflammatory skin disease that requires long-term control of symptoms like itch and sleep loss and improvement in quality of life, in addition to reduction of clinical signs. Lebrikizumab is a selective interleukin-13 inhibitor approved in the European Union, United Kingdom, United Arab Emirates, Canada, and Japan for treatment of moderate-to-severe atopic dermatitis in adults and adolescents. Here, we assess the magnitude of changes across signs and symptoms of atopic dermatitis with lebrikizumab monotherapy over the 16-week induction period in two phase 3 studies, ADvocate1 and ADvocate2. METHODS: Eligible adults (aged ≥ 18 years) and adolescents (aged 12 to < 18 years and weighing ≥ 40 kg) with moderate-to-severe atopic dermatitis were randomized to receive either 250 mg of lebrikizumab or placebo subcutaneously every two weeks. Least squares mean percentage change from baseline through week 16 was compared between lebrikizumab and placebo using mixed model repeated measure analysis for the following endpoints: Eczema Area and Severity Index (EASI), Pruritus Numeric Rating Scale (NRS), Sleep-Loss Scale, Patient-Oriented Eczema Measure (POEM), and Dermatology Life Quality Index (DLQI). RESULTS: In both trials, significant (P < 0.05) improvements were observed for lebrikizumab treatment compared with placebo at each 2-week timepoint for EASI, Pruritus NRS, Sleep-Loss Scale, and POEM, and at each 4-week timepoint for DLQI, through week 16. Statistically significant (P < 0.001) improvements were observed at 16 weeks for lebrikizumab treatment versus placebo in ADvocate1/ADvocate2 for EASI (71.9%/75.0% vs. 35.6%/43.3%), Pruritus NRS (53.3%/46.3% vs. 21.4%/18.0%), Sleep-Loss Scale (57.7%/55.6% vs. 23.9%/25.5%), POEM (54.4%/45.8% vs. 18.8%/16.9%), and DLQI (64.2%/60.5% vs. 28.5%/32.2%). Patient photos show improvements in skin appearance when disease measures improve. CONCLUSIONS: Lebrikizumab monotherapy resulted in significant and fast improvements in multiple dimensions of disease (clinical signs, symptoms, and quality of life) over 16 weeks in patients with moderate-to-severe atopic dermatitis.

Assessing Participants' Experiences with Vitiligo from Patient Interviews.

INTRODUCTION: Vitiligo is an autoimmune disease, causing skin depigmentation. Individuals with vitiligo incur substantial psychosocial burden and have expressed frustration with their treatments. Here, we describe the burden of vitiligo and opinions on what constitutes meaningful change among participants of two qualitative interview studies. METHODS: Qualitative interviews were conducted with a subgroup of adolescent and adult participants with vitiligo from two pivotal phase 3 clinical trials of ruxolitinib cream (Study 1) and a real-world panel (Study 2). Participants were asked about their disease burden, treatment goals, importance of facial/body improvement (treatment satisfaction: scale range 0-10), and meaningfulness of change (yes/no). RESULTS: A total of 36 participants from Study 1 and 23 from Study 2 were interviewed. In Study 1, the highest degree of impact was on reduced self-esteem (facial lesions, 62.5%; body lesions, 55.6%), social inhibition (facial lesions, 65.6%; body lesions, 61.1%), and sun sensitivity (facial lesions, 31.3%; body lesions, 55.6%). Most participants (83.3%) reported that facial improvement was equally (36.1%) or more important (47.2%) than body improvement, with mean treatment satisfaction of 8.1 and 6.9, respectively. Meaningful change was reported by 83.3% and 92.9% of participants with 50-74% and ≥ 75% improvement per the facial Vitiligo Area Scoring Index, respectively, and by 82.6% of participants with ≥ 25% improvement per the total Vitiligo Area Scoring Index per Study 1 outcomes at Week 24. In Study 2, most (82.6%) participants felt that the noticeability of their vitiligo affected their behavior. Nearly all (87.0%) said that an ideal treatment would repigment or return natural color to their facial skin; 56.5% considered ≥ 50% facial repigmentation to be the smallest meaningful improvement. CONCLUSIONS: Participants from both qualitative interviews expressed substantial psychosocial burden. Repigmentation in both facial and body vitiligo were important, with meaningful change determined to be ≥ 50% facial repigmentation and ≥ 25% body repigmentation.

Vitiligo is an autoimmune disease that causes white patches to appear on the skin, affecting about 2% of people worldwide. People with vitiligo often have poor quality of life due to their disease and frequently do not believe that treatments work. We explored how people with vitiligo felt about their disease, and asked what hopes they had for treatment. Individual telephone interviews were conducted with 36 adolescents and adults with vitiligo from two clinical studies (Study 1) and 23 adolescents and adults with vitiligo from a real-world panel (Study 2) in the USA and Canada. Those from Study 1 said that their vitiligo caused them to have low self-esteem and to feel lonely. Most said that it was as important or more important to restore color to white patches on their face (i.e., repigmentation) than the body. Most achieving repigmentation of more than 50% on the face or more than 25% on the body were pleased with their treatment. In Study 2, most people said that their disease affected their behavior, and nearly all said that completely restoring color to their facial skin (i.e., 100% repigmentation) was important. Over half said that the smallest change they thought was important was more than 50% facial repigmentation. In short, people with vitiligo in two interview studies said that their vitiligo affected their quality of life. Most people with vitiligo in these studies reported that it was important to repigment more than 50% on the face and more than 25% on the body.

Prevalence and clinical impact of topical corticosteroid phobia among patients with chronic hand eczema - findings from the Danish Skin Cohort.

BACKGROUND: Topical corticosteroid phobia is associated with poor treatment adherence and is common among patients with skin disease. Knowledge about corticosteroid phobia and treatment adherence among patients with chronic hand eczema (CHE) is limited. OBJECTIVES: Investigate patient-reported outcomes regarding topical corticosteroids (TCS), and their impact on treatment adherence in CHE patients. METHODS: CHE patients from the Danish Skin Cohort answered a questionnaire including the Topical Corticosteroid Phobia (TOPICOP) scale and Medication Adherence Report Scale (MARS-5). Response rate was 69.2%. RESULTS: Of 927 with CHE, 75.5% totally or almost agreed that TCS damage the skin, 48.9% totally or almost agreed that TCS would affect their future health and 36.3% reported some degree of fear of TCS even though they were unaware of any TCS-associated risks. Most patients (77.9%) always or often stop treatment as soon as possible while 54.8% always or often wait as long as possible before starting treatment. Overall, 38.8% reported that they had taken less medicine than prescribed and 54.0% had stopped treatment throughout a period. Treatment adherence decreased with increasing corticosteroid phobia (p=0.004). LIMITATIONS: TOPICOP has not been validated in CHE patients. CONCLUSIONS: Corticosteroid phobia is common among CHE patients and negatively associated with treatment adherence.

Ritlecitinib, a JAK3/TEC family kinase inhibitor, stabilizes active lesions and repigments stable lesions in vitiligo.

The efficacy of ritlecitinib, an oral JAK3/TEC family kinase inhibitor, on active and stable lesions was evaluated in patients with active non-segmental vitiligo in a phase 2b trial (NCT03715829). Patients were randomized to placebo or daily ritlecitinib 50 mg (with or without 4-week 100-mg or 200-mg loading dose), 30 mg, or 10 mg for 24 weeks. Active lesions showed greater baseline expression of inflammatory/immune markers IFNG and CCL5, levels of CD103, and T-cell infiltrates than stable lesions. Patients with more active than stable vitiligo lesions showed higher baseline serum levels of CXCL9 and PD-L1, while patients with more stable than active lesions showed higher baseline serum levels of HO-1. At Week 24, ritlecitinib 50 mg significantly stabilized mean percent change from baseline in depigmentation extent in both active lesions and stable lesions vs. placebo-response, with stable lesions showing greater repigmentation. After 24 weeks of treatment, ritlecitinib 50 mg increased expression of melanocyte markers in stable lesions, while Th1/Th2-related and co-stimulatory molecules decreased significantly in both stable and active lesions. Serum from patients with more active than stable lesions showed decreased levels of ICOS and NK cell activation markers. These data, confirmed at transcription/protein levels, indicate that stable lesion repigmentation occurs early with ritlecitinib, while active lesions require stabilization of inflammation first.

Once-daily upadacitinib versus placebo in adults with extensive non-segmental vitiligo: a phase 2, multicentre, randomised, double-blind, placebo-controlled, dose-ranging study.

Background: Janus kinase (JAK) inhibition is a promising approach for treating vitiligo. We aimed to assess the efficacy and safety of upadacitinib, an oral selective JAK inhibitor, in adults with non-segmental vitiligo. Methods: This was a phase 2, multicentre, randomised, double-blind, placebo-controlled, dose-ranging study completed at 33 clinical centres in the United States, Canada, France, and Japan. Eligible patients were aged 18-65 years with non-segmental vitiligo and had a Facial Vitiligo Area Scoring Index (F-VASI) ≥0.5 and a Total Vitiligo Area Scoring Index (T-VASI) ≥5. Patients were randomly assigned (2:2:2:1:1) using an interactive response technology to receive upadacitinib 6 mg (UPA6), upadacitinib 11 mg (UPA11), upadacitinib 22 mg (UPA22), or placebo (PBO; preassigned to switch to either UPA11 or UPA22 in period 2) once daily for 24 weeks (period 1). For weeks 24-52 (period 2), patients randomly assigned to upadacitinib continued their treatment, and patients receiving PBO switched to their preassigned upadacitinib dose in a blinded fashion. The primary endpoint was the percent change from baseline in F-VASI at week 24. Efficacy was analysed in the intention-to-treat population, and safety was examined in all randomly assigned patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, number NCT04927975. Findings: Between June 16, 2021, and June 27, 2022, 185 patients (including 115 [62%] who were female and 70 [38%] who were male) were randomly assigned to UPA6 (n = 49), UPA11 (n = 47), UPA22 (n = 43), or PBO (n = 46). At week 24, the LS mean difference versus PBO in the percent change from baseline in F-VASI was -7.60 (95% CI -22.18 to 6.97; p = 0.3037) for UPA6, -21.27 (95% CI -36.02 to -6.52; p = 0.0051) for UPA11, and -19.60 (95% CI -35.04 to -4.16; p = 0.0132) for UPA22. The LS mean difference versus PBO in the percent change from baseline in T-VASI was -7.45 (95% CI -16.86 to 1.96; p = 0.1198) for UPA6, -10.84 (95% CI -20.37 to -1.32; p = 0.0259) for UPA11 and -14.27 (95% CI -24.24 to -4.30; p = 0.0053) for UPA22. Ongoing treatment with upadacitinib induced continuous skin repigmentation over time without reaching a plateau through week 52. The rates for study drug discontinuation and serious treatment-emergent adverse events (TEAEs) were higher in the UPA22 group than in the UPA11 and UPA6 groups. Eight serious TEAEs, including one death of unknown cause and one case of infiltrating lobular breast carcinoma, were reported through 52 weeks; only two serious TEAEs (coronary artery arteriosclerosis [UPA6 (n = 1)] and non-fatal ischemic stroke [UPA11 (n = 1)]) were deemed by the investigator to have a reasonable possibility of being related to study drug. The one case of breast cancer in the UPA11 group was deemed unrelated to study drug, and the one death of unknown cause in the UPA22 group was reviewed and adjudicated and was deemed to be unrelated to study drug. The most common TEAEs were COVID-19, headache, acne, and fatigue. No new safety signals were observed. Interpretation: Upadacitinib monotherapy led to substantial repigmentation of both facial and total body vitiligo lesions and may offer an effective treatment option for adults with extensive non-segmental vitiligo. Based on these findings, upadacitinib 15 mg is being investigated in adults and adolescents with non-segmental vitiligo in an ongoing phase 3 randomised controlled trial. Funding: AbbVie Inc.

Disease Course, Treatment Patterns and Goals Among Patients with Non-segmental Vitiligo Across Europe and the United States.

INTRODUCTION: There is currently a lack of research regarding disease course and burden as well as treatment patterns and goals in patients with non-segmental vitiligo (NSV). The aim of this analysis was to evaluate disease course, treatment patterns and goals in patients with NSV. METHODS: This analysis used secondary data from the Adelphi Real World Vitiligo Disease Specific Programme™ 2021, specifically, a survey of physicians and their adult and adolescent patients with NSV. Physicians categorized patients by the extent of NSV at time of survey completion as mild, moderate or severe/very severe. Physician-reported patient information included demographics, current/previously prescribed NSV therapies, treatment satisfaction and the Vitiligo Noticeability Scale (VNS). Patients completed a survey on treatment satisfaction and the VNS. Treatment pattern data were stratified by disease extent and Fitzpatrick skin type. RESULTS: At survey completion, physicians reported that 38, 50 and 12% of patients (N = 1865) had improving, stable and deteriorating/progressing disease, respectively. Most patients (96%) with mild disease at treatment initiation still had mild disease at the time of survey completion. More than half of patients with moderate disease (62%) or severe/very severe disease (57%) at treatment initiation still had moderate or severe/very severe disease at survey completion. Topical calcineurin inhibitors (TCIs) were the most common treatment in 40% of patients followed by phototherapy in 30%. Patients hoped for re-pigmentation (mild 56%, moderate 62%, severe/very severe 66%), reduction (mild 50%, moderate 56%, severe/very severe 49%) or cessation of affected areas with vitiligo (mild 48%, moderate 54%, severe/very severe 43%). CONCLUSION: The study findings indicate that a significant proportion of patients with NSV are not improving on current treatments, most commonly TCIs and phototherapy. The results highlight the unmet need for novel and effective therapies to substantially improve re-pigmentation, an important treatment goal for patients with NSV.

Actinic keratosis: Current challenges and unanswered questions.

Actinic keratoses (AK) are common skin lesions associated with chronic exposure to sun. They are believed to be precursors of malignancy as they potentially may progress to invasive squamous cell carcinomas. The goal of current therapies is to reduce the number of AK and to prevent future cancer development. This review aims at providing an overview of the hallmarks of AK and skin field cancerization. We discuss epidemiology trends, risk factors and the state of the art and evidence of the current treatments. We review key figures of AK prevalence from different countries with regard to skin cancer risk and the associated economic burden of AK. We discuss the mutational status in AK lesions and the difficulties encountered by clinicians in evaluating AK visible and invisible lesions, referring to the concept of field cancerization. Based on a systematic literature review, we further evaluate the available treatment options. The presence of subclinical skin alterations in the periphery of visible AK lesions has gained a particular attention as those non-visible lesions are known to contain the same genetic changes as those found in the AK lesions themselves, prompting the concept of 'field cancerization'. Therefore, AK treatment guidelines now recognize the importance of treating the field in patients with AK. A recent systematic literature review and network meta-analysis showed that 5-FU interventions were associated with the best efficacy and a satisfactory acceptability profile compared with other field-directed therapies used in the treatment of AK. Although AK are considered quite common, they lack an accurate descriptive definition and conclusive epidemiologic data. Limited public awareness is a barrier to early and effective treatment, including prevention strategies. While different treatment options are available, there is still a limited understanding of long-term outcomes of treatment as measured by recurrence of cancer prevention.

Sun exposure and protection habits: Self-reported attitudes, knowledge and behaviours.

BACKGROUND: As exposure to UV radiation is the primary modifiable environmental risk factor associated with skin cancer, it remains the principal focus of most prevention strategies. Numerous sun protection campaigns have been implemented worldwide; however, their impact on the actual incidence and mortality rates of skin cancer seems to be limited. To create successful skin cancer prevention campaigns, it is important to have a comprehensive understanding of individuals' attitudes and behaviours regarding sun protection. The aim of the current study was to determine and report on the prevalence of self-reported attitudes, knowledge and behaviours regarding two of the major sun protection recommendations-avoidance of sun exposure and use of sunscreens-in an international representative sample across five continents. METHODS: This cross-sectional study was conducted in 20 countries using a web-based online survey. FINDINGS: A total of 50,552 individuals, comprising 25,388 men (50.22%) and 25,164 women (49.78%), participated in the survey. Among them, 83.2% reported having been voluntarily exposed to the sun (for sun-basking reasons) at least once in the last 12 months, and 47.96% acknowledged being exposed to the sun between the hours of 10 AM and 4 PM. The primary reason for non-adherence was that these hours were the most convenient times (32.28%). Only 24.05% reported applying sunscreen every 2 h when outdoors. Forgetfulness was the primary reason as provided by 27.79% of participants. Males and older age groups were less likely to adopt sun-protective behaviours around the world. Forgetfulness and the challenges posed by time constraints seem to be the biggest barriers to proper adherence. INTERPRETATION: These findings should prompt the collaboration with health authorities and the manufacturers to enhance adherence by setting reasonable sunscreen prices and creating formulations that make their application less burdensome.

Estimating the burden of vitiligo: a systematic review and modelling study.

BACKGROUND: Vitiligo is a chronic autoimmune disease characterised by depigmented skin patches, which can pose substantial psychosocial challenges particularly in individuals with dark skin tones. Despite its impact on quality of life, there is an absence of standardised global epidemiological data. We sought to address this gap with the present study. METHODS: In this study we did a systematic review and modelling analysis to estimate the global, regional, and national prevalence and incidence of vitiligo. We did a comprehensive search of nine digital libraries (PubMed, Embase, Web of Science, Scientific Electronic Library Online, KCI Korean Journal Database, Russian Science Citation Index, Western Pacific Region Index Medicus, Informit, and Health Research and Development Information Network) from inception up to May 25, 2023. We included cross-sectional or cohort studies reporting the incidence rate or prevalence of vitiligo, or data from which incidence rate or prevalence could be calculated, in the general population of a country or area of a country. Summary estimate data were extracted. A main outcome was to estimate the worldwide, regional, and country-specific lifetime prevalence of vitiligo diagnosed by physicians or dermatologists among the general population and in adults and children (as per age groups defined in included studies). We used a Bayesian hierarchical linear mixed model to estimate prevalence, and calculated number of affected individuals using the UN population structure in 2022. In estimating lifetime prevalence, studies reporting point or period prevalence were excluded. Our other main outcome was to estimate incidence rates of vitiligo, but due to a small number of studies, the data on incidence were presented in a descriptive summary. This study was registered on PROSPERO, CRD42023390433. FINDINGS: Our search identified 22 192 records, of which 90 studies met our inclusion criteria. Of these studies, six focused on the incidence of vitiligo, 79 reported on the prevalence of vitiligo, and five provided data on both incidence and prevalence. 71 studies reported on lifetime prevalence. In the most recent years studied, incidence rates in the general population ranged from 24·7 cases (95% CI 24·3-25·2) per 100 000 person-years in South Korea in 2019, to 61·0 cases (60·6-61·4) in the USA in 2017. In individual studies, incidence rates showed an increasing trend over the periods studied. The global lifetime prevalence of vitiligo diagnosed by a physician or dermatologist was estimated at 0·36% (95% credible interval [CrI] 0·24-0·54) in the general population (28·5 million people [95% CrI 18·9-42·6]), 0·67% (0·43-1·07) in the adult population (37·1 million adults [23·9-58·9]), and 0·24% (0·16-0·37) in the child population (5·8 million children [3·8-8·9]). Vitiligo prevalence was higher in adults than in children across all regions. Central Europe and south Asia reported the highest prevalence (0·52% [0·28-1·07] and 0·52% [0·33-0·82], respectively, in the general population). INTERPRETATION: This study highlights the need for standardised epidemiological data collection globally to inform public health policies and improve vitiligo diagnosis and management. Emphasis on the impact on individuals with darker skin tones is crucial to reducing stigma and improving quality of life. Furthermore, our study highlights the need to conduct more research in regions and populations that have been historically under-represented, to effectively address the worldwide burden of vitiligo. FUNDING: None.

Expert Recommendations on Use of Topical Therapeutics for Vitiligo in Pediatric, Adolescent, and Young Adult Patients.

Importance: Evidence-based recommendations for the treatment of vitiligo in pediatric, adolescent, and young adult patients in the US are needed. Objective: To develop evidence- and consensus-based expert recommendations on the diagnosis and treatment of vitiligo in young patients. Evidence Review: A process was developed to produce consensus recommendations addressing questions regarding pediatric vitiligo. A librarian-conducted literature review was performed using articles that met the inclusion criteria: published in English, containing primary data (including meta-analysis) and pediatric-specific data, and analysis of 6 or more patients. Included articles were graded by the Strength of Recommendation Taxonomy criteria and Oxford Centre for Evidence-based Medicine's Levels of Evidence and Grades of Recommendation. Research questions were reviewed on May 9, 2022, through a video conference. One month after the conference, participants participated in an online survey documenting their level of agreement with the generated statements, using a 5-point Likert scale. Findings: Articles on topical corticosteroids and/or topical calcineurin inhibitors (n = 50), topical Janus kinase inhibitors (n = 5), pseudocatalase (n = 2), and microdermabrasion (n = 2) met inclusion criteria. Forty-two recommendations were made on the diagnosis of vitiligo and optimal topical therapeutics, with 33 recommendations obtaining a 70% or greater composite agreement and strong agreement. Topical calcineurin inhibitors twice daily, topical corticosteroids with time limitation due to atrophy risk, and topical ruxolitinib, 1.5%, cream-used off-label for patients younger than 12 years and limited to nonsegmental vitiligo-were identified as evidence-based first-line therapies in the management of pediatric and adolescent patients, with specific guidance on age-based data, minimum therapeutic trial of 6 months or greater, prolonged therapy to prevent recurrence, and the positive benefit of coordinated use of UV therapeutic sources. Conclusions and Relevance: Evidence supports the use of topical calcineurin inhibitors, topical corticosteroids, and topical Janus kinase inhibitors as effective therapeutics for vitiligo in pediatric, adolescent, and young adult patients, with specific decisions on choice of agent based on factors such as site location, body surface area, and age.

A randomized trial of a wearable UV dosimeter for skin cancer prevention.

Background: Non-melanoma skin cancer (NMSC) is the most prevalent cancer in the United States. Despite guidelines on ultraviolet (UV) avoidance, it remains difficult for people to assess their exposure, as UV is invisible and the onset of UV-induced symptoms is delayed. Methods: In a prospective randomized trial, 97 elderly patients with a history of actinic keratoses (AK) were followed over 6 months. Fifty patients received UV counseling from a dermatologist and a wearable UV dosimeter that provided real-time and cumulative UV exposure. Forty-seven patients received only UV counseling from a dermatologist. Results: Over 75% of participants recorded UV exposure at least once a week during the summer. After 6 months of intervention, when comparing the device group to the control group, we observed a non-significant 20% lower ratio of incidence rates of AKs (95% CI = [-41, 55%], p-value = 0.44) and a significant 95% lower ratio of incidence rates of NMSCs (95% CI = [33, 99.6%], p-value = 0.024). Surveys demonstrated that the control group's score in self-perceived ability to participate in social activities significantly increased by 1.2 (p-value = 0.04), while in the device group, this score non-significantly decreased by 0.9 (p-value = 0.1). We did not observe changes, or between-group differences, in anxiety and depression surveys. Conclusion: This pilot clinical trial has a short duration and a small sample size. However, device adherence and quality of life questionnaires suggest a smartphone-connected wearable UV dosimeter is well accepted by an elderly population. This trial also indicates that a wearable UV dosimeter may be an effective behavioral change tool to reduce NMSC incidence in an elderly population with a prior history of AKs.Clinical trial registration: clinicaltrials.gov, identifier NCT03315286.

Whole-Body Positron Emission Tomography with 18F-Fluorodeoxyglucose/Magnetic Resonance Imaging as a Screening Tool for the Detection of Malignant Transformation in Individuals with Neurofibromatosis Type 1.

Malignant peripheral nerve sheath tumors (MPNSTs) are the leading cause of death in patients with neurofibromatosis type 1. They can result from premalignant neurofibromas, including neurofibromas with atypia and atypical neurofibromatous neoplasms of uncertain biologic potential. Some phenotypic characteristics have been described as associated with their development. The aim of this study was to outline our use of whole-body positron emission tomography with 18F-fluorodeoxyglucose/magnetic resonance imaging in adults with neurofibromatosis type 1, especially in the screening of asymptomatic individuals with a higher risk of developing an MPNST, and to study its impact on neurofibroma classification (malignant vs premalignant) and MPNST staging over time. Individuals with neurofibromatosis type 1 who underwent a positron emission tomography with 18F-fluorodeoxyglucose/magnetic resonance imaging between 2017 and 2021 were included, analyzing separately the screened population. Maximum standard uptake value and diffusion-weighted imaging were assessed. Biopsy/surgery confirmed the diagnosis. In all, 345 positron emission tomography with 18F-fluorodeoxyglucose/magnetic resonance imaging were performed in 241 patients, including 149 asymptomatic (62%) but at-risk patients. Eight MPNSTs in 8 screened individuals (5%), 6 neurofibromas with atypia in 4 individuals (3%), and 29 atypical neurofibromatous neoplasms of uncertain biologic potential in 23 individuals (15%) were diagnosed. Over time, the proportion of grade 3 MPNST and the malignant/premalignant ratio in screened individuals significantly decreased (P = .03 and P < .001, respectively). This study emphasizes the diagnostic and screening performances of whole-body positron emission tomography with 18F-fluorodeoxyglucose/magnetic resonance imaging in adults with neurofibromatosis type 1.

Stigma in vitiligo: associated factors and severity strata of the Patient Unique Stigmatization Holistic tool in Dermatology (PUSH-D) score.

BACKGROUND: Vitiligo is the most common cause of skin depigmentation worldwide. Patients with vitiligo may experience stigma and this needs to be addressed. OBJECTIVES: To evaluate stigma in patients with vitiligo, search for associated factors and establish severity strata for the Patient Unique Stigmatization Holistic tool in Dermatology (PUSH-D) for patients with vitiligo. METHODS: We conducted a cross-sectional study in ComPaRe Vitiligo, an e-cohort of adult patients with vitiligo. Stigmatization was assessed using the PUSH-D, a recently validated dermatology-specific stigmatization assessment tool. We conducted univariate and multivariable linear regression to identify patient and disease factors associated with the stigmatization. We used an anchor-based approach to define severity strata for the PUSH-D. RESULTS: In total, 318 patients participated (mean age 49.7 years; 73.9% women). Fitzpatrick skin phototype IV-VI, severe facial involvement (high Self-Assessment Vitiligo Extent Score of the face) and depression (high Patient Health Questionnaire-9 score) were positively -associated with a higher stigmatization score, although this association was weak [r = 0.24 (P < 0.001) and r = 0.30 (P < 0.001), respectively]. PUSH-D cutoff values that best discriminated patients with high and low stigma, as defined by the anchor question, were 13 and 23 (κ = 0.622, 95% confidence interval 0.53-0.71). CONCLUSIONS: Our study is the first to use a skin-specific stigmatization tool to assess stigma in patients with vitiligo. Creating strata helps to better interpret the PUSH-D in daily practice and may facilitate its use in clinical trials.

Vitiligo is an acquired autoimmune condition characterized by well-defined depigmented patches of skin on the body. The condition affects approximately 1% of the world's population and those living with vitiligo have long experienced stigmatization. Despite the fact that previous research has investigated the correlation between stigma and vitiligo using non-specific stigma tools, to our knowledge, no study has specifically assessed stigma in people with vitiligo. This study was carried out among French patients with vitiligo to evaluate both felt and actual stigma using the Patient Unique Stigmatization Holistic tool in Dermatology (PUSH-D), a new skin-specific stigma score. We also looked for correlations between PUSH-D scores and other questionnaires measuring levels of anxiety (GAD-7) and depression (PHQ-9). We found that PHQ-9 scores for depression were significantly positively correlated with PUSH-D scores, although these correlations were weak. When examining which factors were associated with higher stigma, we found that darker skin phototypes and severe facial involvement predicted higher stigma. However, we found that hand involvement did not. Overall, vitiligo is associated with a lot of stigma and it has been shown to be a barrier to employment. Therefore, an objective evaluation of vitiligo is required in order to facilitate access and reimbursement of treatment (including those existing and under development). The findings from this study highlight how further research is needed with more diverse groups of people, to better objectify stigma associated with vitiligo.

A core outcome domain set to assess cutaneous neurofibromas related to neurofibromatosis type 1 in clinical trials.

BACKGROUND: Cutaneous neurofibromas (cNF) are considered one of the highest burdens of neurofibromatosis type 1 (NF1). To date, no medical treatment can cure cNF or prevent their development. In that context, there is an urgent need to prepare and standardize the methodology of future trials targeting cNF. OBJECTIVES: The objective was to develop a core outcome domain set suitable for all clinical trials targeting NF1-associated cNF. METHODS: The validated approach of this work consisted of a three-phase methodology: (i) generating the domains [systematic literature review (SLR) and qualitative studies]; (ii) agreeing (three-round international e-Delphi consensus process and working groups); and (iii) voting. RESULTS: (i) The SLR and the qualitative studies (three types of focus groups and a French e-survey with 234 participants) resulted in a preliminary list of 31 candidate items and their corresponding definitions. (ii) A total of 229 individuals from 29 countries participated in the first round of the e-Delphi process: 71 patients, relatives or representatives (31.0%), 130 healthcare professionals (HCPs, 56.8%) and 28 researchers, representatives of a drug regulatory authority, industry or pharmaceutical company representatives or journal editors (12.2%). The overall participation rate was 74%. After round 2, five candidate items were excluded. Between rounds 2 and 3, international workshops were held to better understand the disagreements among stakeholders. This phase led to the identification of 19 items as outcome subdomains. (iii) The items were fused to create four outcome domains ('clinical assessment', 'daily life impact', 'patient satisfaction' and 'perception of health') and prioritized. The seven items that did not reach consensus were marked for the research agenda. The final core outcome domain set reached 100% of the votes of the steering committee members. CONCLUSIONS: Although numerous outcomes can be explored in studies related to cNF in NF1, the present study offers four outcome domains that should be reported in all trial studies, agreed on by international patients, relatives and representatives of patients; HCPs; researchers, representatives of drug regulatory authorities or pharmaceutical companies and journal editors. The next step will include the development of a set of core outcome measurement instruments to further standardize how these outcomes should be assessed.
