BACKGROUND: Skin cancers are the most common group of cancers diagnosed worldwide. Aging and sun exposure increase their risk. The decline in the number of dermatologists is pushing the issue of dermatological screening back onto family doctors. Dermoscopy is an easy-to-use tool that increases the sensitivity of melanoma diagnosis by 60% to 90%, but its use is limited due to lack of training. The characteristics of "ideal" dermoscopy training have yet to be established. We created a Moodle (Moodle HQ)-based e-learning course to train family medicine residents in dermoscopy. OBJECTIVE: This study aimed to evaluate the evolution of dermoscopy knowledge among family doctors immediately and 1 and 3 months after e-learning training. METHODS: We conducted a prospective interventional study between April and November 2020 to evaluate an educational program intended for family medicine residents at the University of Montpellier-Nîmes, France. They were asked to complete an e-learning course consisting of 2 modules, with an assessment quiz repeated at 1 (M1) and 3 months (M3). The course was based on a 2-step algorithm, a method of dermoscopic analysis of pigmented skin lesions that is internationally accepted. The objectives of modules 1 and 2 were to differentiate melanocytic lesions from nonmelanocytic lesions and to precisely identify skin lesions by looking for dermoscopic morphological criteria specific to each lesion. Each module consisted of 15 questions with immediate feedback after each question. RESULTS: In total, 134 residents were included, and 66.4% (n=89) and 47% (n=63) of trainees fully participated in the evaluation of module 1 and module 2, respectively. This study showed a significant score improvement 3 months after the training course in 92.1% (n=82) of participants for module 1 and 87.3% (n=55) of participants for module 2 (P<.001). The majority of the participants expressed satisfaction (n=48, 90.6%) with the training course, and 96.3% (n=51) planned to use a dermatoscope in their future practice. Regarding final scores, the only variable that was statistically significant was the resident's initial scores (P=.003) for module 1. No measured variable was found to be associated with retention (midtraining or final evaluation) for module 2. Residents who had completed at least 1 dermatology rotation during medical school had significantly higher initial scores in module 1 at M0 (P=.03). Residents who reported having completed at least 1 dermatology rotation during their family medicine training had a statistically significant higher score at M1 for module 1 and M3 for module 2 (P=.01 and P=.001). CONCLUSIONS: The integration of an e-learning training course in dermoscopy into the curriculum of FM residents results in a significant improvement in their diagnosis skills and meets their expectations. Developing a program combining an e-learning course and face-to-face training for residents is likely to result in more frequent and effective dermoscopy use by family doctors.

BACKGROUND: Angioedema (AE) manifests with intermittent, localized, self-limiting swelling of the subcutaneous and/or submucosal tissue. AE is heterogeneous, can be hereditary or acquired, occurs only once or be recurrent, with or without wheals, due to mast cell mediators, bradykinin or other mechanisms. Currently, different taxonomic systems are used, making it difficult to compare the results of studies, develop multicenter collaboration, and harmonize treatments of AE patients. OBJECTIVE: To develop a consensus on the definition, acronyms, nomenclature, and classification of angioedema (DANCE). METHODS: The initiative involved 91 experts from 35 countries and was endorsed by 53 scientific, medical societies, and patient organizations. A consensus was reached by online discussion and voting using the Delphi process over a period of 16 months (June 2021 to November 2022). RESULTS: The DANCE initiative resulted in an international consensus on the definition, classification and terminology of AE. The new consensus classification features five types and endotypes of AE and a harmonized vocabulary of abbreviations and acronyms. CONCLUSION: The DANCE classification complements current clinical guidelines and expert consensus recommendations on the diagnostic workup and treatment of AE. DANCE does not replace current clinical guidelines and expert consensus algorithms and should not be misconstrued in a way that affects reimbursement of medicines prescribed by a physician using sound clinical judgment. We anticipate that the new AE taxonomy and nomenclature will harmonize and facilitate AE research and clinical studies, thereby improving patient care.

BACKGROUND: Chronic spontaneous urticaria (CSU) can present with non-skin-related symptoms (NSRS), including recurrent unexplained fever, joint/bone/muscle pain (JBMP), and malaise, which also occur in other conditions that manifest with wheals (e.g., urticarial vasculitis or autoinflammatory disorders) or without wheals (e.g., infection). OBJECTIVE: We sought to determine the rate of patients with CSU affected by fever, JBMP and malaise, their trigger factors, links with clinical and laboratory characteristics, and their impact on everyday life and treatment responses. METHODS: We analyzed baseline data from the Chronic Urticaria Registry (CURE) of 2,521 patients with CSU who were ≥16 years old. RESULTS: One-third of CSU patients (31.2%, 786/2,521) had ≥1 NSRS, including recurrent fever (5.3%), JBMP (19.1%), and/or malaise (18.6%). In a multivariable analysis, having ≥1 of these NSRS correlated with food and infection as trigger factors of urticaria (adjusted odds ratio [aOR]=1.7 and 1.5), wheals of ≥24 hours duration (aOR=2.5), sleep disturbance (aOR=2.4), anxiety (aOR=2.8), comorbid atopic dermatitis (aOR=2.1), gastrointestinal disease (aOR=1.8), elevated leukocytes (aOR=1.7) and erythrocyte sedimentation rate (aOR=1.5). In a bivariate analysis, these NSRS were additionally associated with higher disease activity (UAS7, median: 21 vs. 14, p=0.009), longer disease duration (years, median: 2 vs. 1, p=0.001), presence of angioedema (74.6% vs. 58.7%, p<0.001), worse quality of life (CU-Q2oL, median: 42 vs. 29, p<0.001) and more frequent poor control of CSU (78% vs. 69%, p<0.001). CONCLUSION: The presence of NSRS in a subpopulation of CSU patients points to a need for better control of the disease, exclusion of comorbid conditions and/or exclusion of urticarial vasculitis and urticarial autoinflammatory diseases.

The human skin virome, unlike commensal bacteria, is an under investigated component of the human skin microbiome. We developed a sensitive, quantitative assay to detect cutaneous human resident papillomaviruses (HPV) and polyomaviruses (HPyV) and we first used it to describe these viral populations at the skin surface of two patients with atopic dermatitis (AD) and psoriasis (PSO). We performed skin swabs on lesional and non-lesional skin in one AD and one PSO patient at M0, M1 and M3. After extraction, DNA was amplified using an original multiplex PCR technique before high throughput sequencing (HTS) of the amplicons (named AmpliSeq-HTS). Quantitative results were ultimately compared with monoplex quantitative PCRs (qPCRs) for previously detected viruses and were significantly correlated (R2 = 0.95, ρ = 0.75). Fifteen and 13 HPV types (mainly gamma and beta-HPVs) or HPyV species (mainly Merkel Cell Polyomavirus (MCPyV)) were detected on the skin of the AD and PSO patients, respectively. In both patients, the composition of the viral flora was variable across body sites but remained stable over time in non-lesional skin samples, mostly colonized with gamma-papillomaviruses. In lesional skin samples, beta-papillomaviruses and MCPyV were the major components of a viral flora more prone to vary over time especially with treatment and subsequent clinical improvement. We believe this method might be further used in extensive studies to further enhance the concept of an individual cutaneous viral fingerprint and the putative role of its alterations through various skin diseases and their treatments.

The impact of chronic urticaria on work has been scarcely reported, whereas its peak incidence is between the ages of 20 and 40. The aim of this study was to assess the occupational impact of chronic urticaria and its treatment, by combining objective and patient-reported data. A monocentric observational study was performed using questionnaires over a 1-year period from 2021 to 2022 in chronic urticaria patients who were in a period of professional activity and agreed to participate. Of the 88 patients included, 55.7% assessed the occupational impact of their chronic urticaria as significant, and even more severe when chronic urticaria was poorly controlled. Some 86% of patients had symptoms at work, in a third of cases aggravated by work. However, occupational physical factors were not associated with an aggravation of inducible chronic urticaria. A total of 20% reported treatment-related adverse effects affecting their work. Despite low absenteeism, presenteeism and reduced productivity were important (> 20%). Six patients (6.8%) had difficulties keeping their work. For 72.7% of the patients, the occupational physician was not informed. The occupational impact of chronic urticaria should be discussed during consultations, particularly when it is insufficiently controlled. The occupational physician should be informed in order to support patients' professional project.

Although current systemic therapies significantly improved the outcome of advanced melanoma, the prognosis of patient with central nervous system (CNS) metastases remains poor especially when clinically symptomatic. We aimed to investigate the efficiency of CNS targets and tolerance of second-line combined anti-PD1/dual-targeted anti-BRAF/anti-MEK therapy implemented in patients with CNS progression after initially efficient first-line combined targeted therapy in patients with BRAF-mutated melanoma in a real-life setting. A monocentric retrospective analysis including all such patients treated from January 2017 to January 2022 was conducted in our tertiary referral center. The response of CNS lesions to second-line triple therapy was assessed through monthly clinical and at least quarterly morphological (according to RECIST criteria) evaluation. Tolerance data were also collected. Seventeen patients were included with a mean follow-up of 2.59 (±2.43) months. Only 1 patient displayed a significant clinical and morphological response. No statistically significant difference was observed between patients receiving or not additional local therapy (mainly radiotherapy) as to response achievement. Immunotherapy was permanently discontinued in 1 patient owing to grade 4 toxicity. Mean PFS and OS after CNS progression were 2.59 and 4.12 months, respectively. In this real-life survey, the subsequent addition of anti-PD1 to combined targeted therapy in melanoma patients with upfront CNS metastases did not result in significant response of CNS targets in most BRAF mutated melanoma patients with secondary CNS progression after initially successful first-line combined targeted therapy.

BACKGROUND: Angioedema (AE) due to acquired C1-inhibitor (C1-INH) deficiency (AAE-C1-INH) is related to excessive consumption of C1-INH or to anti-C1-INH antibodies, and is frequently associated with lymphoproliferative syndromes or monoclonal gammopathies. Standard of care for prophylactic treatment in this condition is not established. Rituximab may be effective to prevent attacks, especially if the lymphoid hemopathy is controlled, but data are scarce. OBJECTIVE: To evaluate efficacy of rituximab in AAE-C1-INH. METHODS: A retrospective multicenter study was carried out in France, including patients with AAE-C1-INH treated with rituximab between April 2005 and July 2019. RESULTS: Fifty-five patients with AAE-C1-INH were included in the study, and 23 of them had an anti-C1-INH antibody. A lymphoid malignancy was identified in 39 patients, and a monoclonal gammopathy in 9. There was no associated condition in 7 cases. Thirty patients received rituximab alone or in association with chemotherapy (n = 25). Among 51 patients with available follow-up, 34 patients were in clinical remission and 17 patients had active AE after a median follow-up of 3.9 years (interquartile range, 1.5-7.7). Three patients died. The presence of anti-C1-INH antibodies was associated with a lower probability of AE remission (hazard ratio, 0.29 [95% CI, 0.12-0.67]; P = .004). Relapse was less frequent in patients with lymphoma (risk ratio, 0.27 [95% CI, 0.09-0.80]; P = .019) and in patients treated with rituximab and chemotherapy (risk ratio, 0.31 [95% CI, 0.12-0.79]; P = .014). CONCLUSIONS: Rituximab is an efficient and well-tolerated therapeutic option in AE, especially in lymphoid malignancies and in the absence of detectable anti-C1-INH antibodies.

Background: Bradykinin angioedemas are a potentially serious side effect of angiotensin-converting enzyme inhibitors (ACEI) and more controversially of angiotensin II receptor blockers (ARB). Their challenging diagnosis is based on the absence of any recurrence after more than 6 months of drug discontinuation; otherwise mast-cell driven angioedemas as a differential diagnosis must be considered. Objective: The aim of this study was to determine the prevalence of recurrent angioedema in patients referred for ACEI/ARB-induced bradykinin angioedema, after more than 6 months of drug discontinuation. Methods: We included ACEI/ARB-treated patients referred for angioedema(s) without hives and unresponsive to antihistamines, after they discontinued ACEI/ARB for at least 6 months. Any C1-inhibitor deficiency was excluded. The primary endpoint was the prevalence of patients with recurrent angioedema after more than 6 months of drug discontinuation and/or developing hives during follow-up. The secondary endpoint was the identification of epidemiological factors associated with any final diagnosis. Results: Thirty-eight of 93 patients (41%) with a suspicion of ACEI/ARB-induced bradykinin angioedema still had recurrent angioedema (n = 27) or developed hives (n = 2) or both (n = 9) after 6 months of drug discontinuation. Good response to icatibant and facial but not oral localization were predictive for the final diagnosis of ACEI/ARB-induced bradykinin angioedema and mast-cell driven angioedema, respectively. Conclusion: In patients referred for acquired angioedema without wheals occurring during ACEI/ARB therapy, 59% finally had a diagnosis of ACEI/ARB-induced bradykinin angioedema whereas 41% were rather diagnosed with mast-cell driven angioedema. The overdiagnosis of ACEI/ARB-induced bradykinin angioedema may deteriorate the management of severe cardiovascular conditions.

BACKGROUND: Omalizumab (OMA) dramatically improves disease control and quality of life in patients with chronic urticaria (CU). OBJECTIVE: We aimed to evaluate the discontinuation patterns of OMA and their determinants in a cohort of French patients with CU. METHODS: We conducted a retrospective multicenter study in 9 French tertiary referral hospitals. All patients diagnosed with either spontaneous (CSU) and/or inducible (CIndU) CU who received at least 1 injection of OMA between 2009 and 2021 were included. We analyzed OMA drug survival and investigated possible determinants using Kaplan-Meier curves and log-rank tests. RESULTS: A total of 878 patients were included in this study; 48.8% had CSU, 10.1% CIndU, and 41.1% a combination of both. OMA was discontinued in 408 patients, but the drug was later reintroduced in 50% of them. The main reason for discontinuing treatment was the achievement of a well-controlled disease in 50% of patients. Half of the patients were still being treated with OMA 2.4 years after the initiation of treatment. Drug survival was shorter in patients with CIndU and in those with an autoimmune background. In atopic patients, OMA was discontinued earlier in patients achieving a well-controlled disease. A longer OMA drug survival was observed in patients with a longer disease duration at initiation. CONCLUSION: In French patients with CU, the drug survival of OMA appears to be longer than that observed in previous studies conducted elsewhere, highlighting discrepancies in prescription and reimbursement possibilities. Further studies are warranted to develop customized OMA treatment schemes based on individual patterns.

Dupilumab is a therapeutic antibody targeting IL-4 and IL-13 receptor subunit alpha used for the treatment of patients with atopic dermatitis (AD). Cases of psoriasis-like reactions induced under dupilumab treatment (dupilumab-induced psoriatic eruption [DI-Pso]) for AD were recently reported. To understand the pathogenesis of DI-Pso, we performed gene expression profiling studies on skin biopsies of DI-Pso (n = 7) compared with those of plaque psoriasis, AD, and healthy controls (n = 4 each). Differential gene expression was performed using enrichment and Gene Ontology analysis. Gene expression was validated by qPCR, and protein levels were assessed by immunohistochemistry. Transcriptomic and protein analysis of DI-Pso compared with that of healthy controls, plaque psoriasis, and AD skins revealed activation of T helper 17/IL-23 pathways associated with a significant expression of IL-36, surrogate marker of pustular psoriasis. By contrast, T helper 2 representative genes' expression was strongly decreased in DI-Pso across comparison. Matching analysis with public data of pustular psoriasis skin corroborated that DI-Pso and pustular psoriasis upstream regulators overlap, greater than the overlap with plaque psoriasis. Furthermore, DI-Pso showed strongly decreased expression of many barrier skin genes compared with healthy controls, plaque psoriasis, and AD. Our data indicate that the pathogenesis of DI-Pso relied on a shift of skin immune responses from a T helper 2 to an IL-36 and T helper 17 polarization and on intensified skin barrier alterations.

BACKGROUND: Human immunoglobulins are used for treating diverse inflammatory and autoimmune disorders. Eczema is an adverse event reported but poorly described. OBJECTIVES: To describe the clinical presentation, severity, outcome, and therapeutic management of immunoglobulin-associated eczema. METHODS: This retrospective and descriptive study included a query of the French national pharmacovigilance database, together with a national call for cases among dermatologists. RESULTS: We included 322 patients. Eczema occurred preferentially in men (78.9%) and in patients treated for neurological pathologies (76%). The clinical presentation consisted mainly of dyshidrosis (32.7%) and dry palmoplantar eczema (32.6%); 5% of cases exhibited erythroderma. Sixty-two percent of the eczema flares occurred after the first immunoglobulin course. Eczema was observed with 13 intravenous or subcutaneous immunoglobulin types and recurred in 84% of patients who maintained the same treatment and in 68% who switched the immunoglobulin type. After immunoglobulin discontinuation, 30% of patients still had persistent eczema. LIMITATIONS: Retrospective study, with possible missing data or memory bias. CONCLUSION: Immunoglobulin-associated eczema occurred with all immunoglobulin types, preferentially in patients with neurologic diseases who required prolonged immunoglobulin treatment. Recurrence was frequent, even after switching the immunoglobulin type, which can lead to a challenging therapeutic situation when immunoglobulin maintenance is required.

BACKGROUND AND OBJECTIVE: Chronic spontaneous urticaria (CSU) is a distressing disease. We report real-world data from the global Chronic Urticaria Registry (CURE) about associations between various CSU states and sleep impairment, plus important health-related quality-of-life (HRQoL) outcomes and compared different methods to assess CSU states. METHODS: CURE data were collected at baseline and 6-monthly follow-ups (FU). Assessments included CSU states using the Urticaria Control Test (UCT), weekly Urticaria Activity Score (UAS7), and Physician Global Assessment (PhyGA) of treatment response. Complete response to treatment (CR, UAS7 = 0), complete control of disease (CC, UCT = 16), and PhyGA = CR were assessed, plus the Dermatology Life Quality Index and the Chronic Urticaria Quality-of-Life Questionnaire (CU-Q2oL) sleep domain. RESULTS: Overall, 2078 patients were included. At baseline, 9.8%, 17.9%, and 42.3% of patients had UCT = 16, UAS7 = 0, or PhyGA = CR, respectively, which increased at FU1 and FU2. Patients with higher UCT scores had better sleep and HRQoL. The presence of angioedema without wheals, episodic disease, omalizumab treatment, and male sex were associated with CC (P < .05). Among 469 patients who achieved CC or CR, 16.4% (n = 77) showed CC or CR with all 3 instruments. Agreement between UCT = 16 and UAS7 = 0 measurements was moderate (κ = 0.581), but poor between UCT = 16 and PhyGA = CR (κ = 0.208). CONCLUSIONS: Few patients had CR/CC of their CSU at baseline entry. Disease control strongly related to good sleep and better HRQoL; therefore, it is important to aim for CR in CSU treatment. Patient-reported UCT and UAS7 assessments demonstrated a more accurate measurement of CSU state versus physician assessments.

BACKGROUND AND OBJECTIVES: Bullous pemphigoid (BP) clinical profile may have evolved during the last 2 decades. A retrospective, single-centre analysis investigated a possible shift of clinical presentation of the disease over time regarding both lesions' clinical pattern and locations and more particularly an increased frequency of characteristics considered as less classical regarding the usual clinical description of BP. PATIENTS AND METHODS: Initial clinical data from all BP patients treated between January 2001 and April 2017 in a reference centre were collected and compared between four 4-year successive chronological subsets (G1 to G4). RESULTS: 213/312 patients retained for final analysis (68.3%) displayed at least one initial non-classical characteristic, mainly head and neck, palmo-plantar, and/or mucosal involvement. Chronological analysis confirmed a significant increase over time of the percentage of patients displaying such features (G1 57.9% vs. G4 73.7%, p = 0.041). CONCLUSION: Changes in BP clinical pattern may have occurred over the last two decades with the progressive emergence of forms with a number of less classical features. No significant clinical difference was observed between patients receiving or not DPP4 inhibitors at the time of diagnosis.

Acquired cold contact urticaria (ACU) is a putatively serious condition, because of the risk of anaphylactic shock whenever patients are massively exposed to cold atmosphere/water, raising the question of the prescription of an "emergency kit" with oral antihistamines and epinephrine auto-injector. We performed an online survey to evaluate how French-speaking urticaria experts manage ACU. According to the 2016 consensus recommendations on chronic inducible urticarias, all the participants perform at least 1 of the available provocation tests and 84.2%, 77.8%, and 88.9% prescribe on-label use of second generation anti-H1 antihistamines (2GAH1) as a first line treatment, updosed 2GAH1 as a second line treatment, and omalizumab as a third line treatment, respectively. Interestingly, 44.4% of the practitioners always prescribe a continuous background treatment, versus 11.1% prescribing only on-demand therapy. Also, 11.7% of participants always prescribe an epinephrine auto-injector, 70.6% sometimes do, and 17.6% never do. Finally, 89.5% authorize swimming under strict conditions but 36.8% and 68.4% contra-indicate other water sports and occupational cold exposure, respectively.

Background: Hereditary angioedema (HAE) is characterized by unpredictable and potentially life-threatening attacks of cutaneous and submucosal swelling. Over the past decade, new agents, based on a better understanding of the underlying biologic mechanisms of HAE, have changed the face of long-term prophylaxis (LTP). Objective: The objective was to describe current practices and unmet needs with regard to LTP for HAE in expert centers in France. Methods: The study was conducted in France in 2020. Based on their experience with patients with HAE who had visited their center at least once in the past 3 years, physicians from 25 centers who are expert in the management of HAE were requested to fill in a questionnaire that encapsulated their active patient list, criteria for prescribing LTP, and medications used. They were asked about potential unmet needs with currently available therapies. They were asked to express their expectations with regard to the future of HAE management. Results: Analysis was restricted to 20 centers that had an active patient file and agreed to participate. There were 714 patients with C1 inhibitor (C1-INH) deficiency, of whom 423 (59.2%) were treated with LTP. Altered quality of life triggered the decision to start LTP, as did the frequency and severity of attacks. Ongoing LTP included androgens (28.4%), progestins (25.8%), lanadelumab (25.3%), tranexamic acid (14.2%), intravenous C1-INHs (5.6%), and recombinant C1-INH (0.7%). Twenty-nine percent of the patents with LTP were considered to still have unmet needs. Physicians' concerns varied among therapies: poor tolerability for androgens and progestins, a lack of efficacy for tranexamic acid and progestins, dosage form, and high costs for C1-INHs and lanadelumab. Physicians' expectations encompassed more-efficacious and better-tolerated medications, easier treatment administration for the sake of improved quality of life of patients, and less-expensive therapies. Conclusion: Despite the recent enrichment of the therapeutic armamentarium for LTP, physicians still expressed unmet needs with currently available therapies.
