RESUMO
BACKGROUND: Dermatologic conditions are estimated to account worldwide for approximately 8% of all visits at emergency departments (EDs). Although rarely life-threatening, several dermatologic emergencies may have a high morbidity. Little is known about ED consultations of patients with dermatological emergencies and their subsequent hospital disposal. OBJECTIVE: We explore determinants and clinical variables affecting patients' disposal and hospitalization of people attending the ED at a Swiss University Hospital, over a 56-month observational period, for a dermatological problem. METHODS: De-identified patients' information was extracted from the hospital electronic medical record system. Generalized estimating equations were used to explore determinants of patient's disposition. RESULTS: Out of 5096 consecutive patients with a dermatological main problem evaluated at the ED, 79% of patients were hospitalized after initial assessment. In multivariable analyses, factors which were significantly associated with an increased admission rate included length of ED stay, age ≥ 45 years, male sex, distinct vital signs, high body mass index, low oxygen saturation, admission time in the ED and number and type of dermatological diagnoses. Only 2.2% of the hospitalized patients were admitted to a dermatology ward, despite the fact that they had dermatological diagnoses critically determining the diagnostic related group (DRG) payment. The number of patients managed by dermatologists during in-patient treatment significantly decreased over the study period. CONCLUSIONS: Our study identifies a number of independent predictors affecting the risk of hospital admission for patients with dermatological conditions, which may be useful to improve patients' disposal in EDs. The results indicate that the dermatological specialty is becoming increasingly marginalized in the management of patients in the Swiss hospital setting. This trend may have significant implications for the delivery of adequate medical care, outcomes and cost-effectiveness. Dermatologists should be more engaged to better position their specialty and to effectively collaborate with nondermatologists to enhance patient care.
RESUMO
PURPOSE: Hyponatremia is the most frequent electrolytic disorder in clinical practice. In addition to neurological symptoms, hyponatremia, even when mild/moderate and chronic, has been related to other manifestations, such as bone demineralization and increased risk of fractures. To better elucidate tissue alterations associated with reduced serum sodium concentration [Na+], we developed an in vivo model of hyponatremia secondary to the Syndrome of Inappropriate Antidiuresis. METHODS AND RESULTS: Hyponatremia was induced in Foxn1nu/nu mice by subcutaneous infusion of the vasopressin analog 1-deamino [8-D-arginine] vasopressin (dDAVP) for 14 days via osmotic mini-pumps. Mice in the control group were infused with isotonic saline solution. Serum [Na+] progressively decreased, with a nadir of 123.4 ± 2.3 mEq/L (mean ± SD, dDAVP 0.3 ng/h) and 111.6 ± 4.7 mEq/L (mean ± SD, dDAVP 0.5 ng/h). Evident signs of liver steatofibrosis were observed at histology in hyponatremic mice. Accordingly, the expression of proteins involved in lipid metabolism (SREBP-1, PPARα and PPARγ) and in myofibroblast formation (αSMA and CTGF) significantly increased. Furthermore, heme oxygenase 1 expression was up-regulated in Kupffer and hepatic stellate cells in the liver of hyponatremic mice. Testis alterations were also observed. In particular, the thickness of the seminiferous epithelium appeared reduced. The expression levels of PCNA and PTMA, which are involved in DNA replication and germ cells maturation, were markedly reduced in the testis of hyponatremic mice. CONCLUSION: Overall, these findings shed new light on the possible consequences of chronic hyponatremia and prompt a more thorough evaluation of hyponatremic patients.

PURPOSE: Hyponatremia, the most frequent electrolyte alteration in clinical practice, has been associated with a worse prognosis in cancer patients. On the other hand, a better outcome has been related to serum sodium normalization. In vitro studies have shown that low extracellular sodium promotes cancer cells proliferation and invasiveness. Tolvaptan, a selective vasopressin receptor type 2 (V2) antagonist, has been effectively used in the last decade for the treatment of hyponatremia secondary to the Syndrome of Inappropriate Antidiuresis. A few in vitro data suggested a direct role of tolvaptan in counteracting cancer progression, so far. The aim of this study was to evaluate the effect and the mechanism of action of tolvaptan in cell lines from different tumours [i.e. colon cancer (HCT-8), hepatocarcinoma (HepG2), neuroblastoma (SK-N-AS)]. METHODS AND RESULTS: First, we showed that these cell lines express the V2 receptor. Tolvaptan significantly reduced cell proliferation with an IC50 in the micromolar range. Accordingly, reduced levels of cAMP, of the catalytic α subunit of PKA, and a reduced pAKT/AKT ratio were observed. Tolvaptan effectively inhibited cell cycle progression, whereas it induced apoptotis. Furthermore, it reduced cell invasiveness. In particular, anchorage-independent growth and the activity of collagenases type IV were blunted in the three cell lines. Accordingly, tolvaptan counteracted the RhoA/ROCK1-2 pathway, which has a pivotal role in regulating cell movement. CONCLUSIONS: Overall, these findings indicate that tolvaptan effectively inhibits tumour progression in vitro. Further studies should clarify whether the V2 receptor might be considered a possible target in anti-cancer strategies in the future.

BACKGROUND: Registry data suggest that people with immune-mediated inflammatory diseases (IMIDs) receiving targeted systemic therapies have fewer adverse coronavirus disease 2019 (COVID-19) outcomes compared with patients receiving no systemic treatments. OBJECTIVES: We used international patient survey data to explore the hypothesis that greater risk-mitigating behaviour in those receiving targeted therapies may account, at least in part, for this observation. METHODS: Online surveys were completed by individuals with psoriasis (globally) or rheumatic and musculoskeletal diseases (RMDs) (UK only) between 4 May and 7 September 2020. We used multiple logistic regression to assess the association between treatment type and risk-mitigating behaviour, adjusting for clinical and demographic characteristics. We characterized international variation in a mixed-effects model. RESULTS: Of 3720 participants (2869 psoriasis, 851 RMDs) from 74 countries, 2262 (60·8%) reported the most stringent risk-mitigating behaviour (classified here under the umbrella term 'shielding'). A greater proportion of those receiving targeted therapies (biologics and Janus Kinase inhibitors) reported shielding compared with those receiving no systemic therapy [adjusted odds ratio (OR) 1·63, 95% confidence interval (CI) 1·35-1·97]. The association between targeted therapy and shielding was preserved when standard systemic therapy was used as the reference group (OR 1·39, 95% CI 1·23-1·56). Shielding was associated with established risk factors for severe COVID-19 [male sex (OR 1·14, 95% CI 1·05-1·24), obesity (OR 1·37, 95% CI 1·23-1·54), comorbidity burden (OR 1·43, 95% CI 1·15-1·78)], a primary indication of RMDs (OR 1·37, 95% CI 1·27-1·48) and a positive anxiety or depression screen (OR 1·57, 95% CI 1·36-1·80). Modest differences in the proportion shielding were observed across nations. CONCLUSIONS: Greater risk-mitigating behaviour among people with IMIDs receiving targeted therapies may contribute to the reported lower risk of adverse COVID-19 outcomes. The behaviour variation across treatment groups, IMIDs and nations reinforces the need for clear evidence-based patient communication on risk-mitigation strategies and may help inform updated public health guidelines as the pandemic continues.

BACKGROUND: In a European study on contact allergy in the general population, it has been hypothesized that the combination of contact allergy to a fragrance together with a history indicating dermatitis at exposure and thereafter subsequent avoidance of scented products implied a diagnosis of allergic contact dermatitis. OBJECTIVES: The primary aim of this study was to validate this hypothesis/algorithm. The secondary aim was to investigate whether there was any association between the outcome of the recent repeated open application test (ROAT) and the patch test reactivity. METHODS: One hundred nine subjects with and without contact allergy to fragrance mix II (FM II) were recruited. Volunteers from six European dermatology clinics participated in the study including a patch test and a ROAT. RESULTS: Twenty-four positive ROAT reactions were noted in total including 20 of those 32 with contact allergy to FM II. None of the volunteers reacted to the vehicle (P < 0.001). More individuals with a positive algorithm had positive ROATs when compared with those with a negative algorithm. However, the difference was not statistically significant (P = 0.12). The lower the patch test concentration eliciting a positive test reaction, the more likely was a positive ROAT and the more likely that the positive ROAT appeared early during the investigative period. CONCLUSIONS: The algorithm used in this study was not validated but it was indicated in this ROAT setup. The stronger the patch test reactivity the more likely was a positive ROAT and the more likely it was that the positive ROAT appeared early during the application period.

BACKGROUND: In a European study on contact allergy in the general population, it was hypothesized that the combination of contact allergy to a fragrance together with a history indicating dermatitis at exposure, and thereafter subsequent avoidance of scented products, implied a diagnosis of allergic contact dermatitis. OBJECTIVES: The primary aim of this study was to validate this hypothesis and algorithm. The secondary aim was to investigate whether there was any association between the outcome of the repeated open application test (ROAT) and the patch test reactivity. METHODS: In total, 109 patients with and without contact allergy to fragrance mix (FM) I were recruited. Volunteers from six European dermatology clinics participated in the study including a patch test and a ROAT. RESULTS: Positive ROAT reactions were noted in 26 of the 44 volunteers with contact allergy to FM I. None of the volunteers reacted to the vehicle (P < 0·001). More individuals with a positive algorithm had positive ROATs than those with a negative algorithm. However, the difference was not statistically significant. The lower the patch test concentration eliciting a positive test reaction, the more likely a positive ROAT and the more likely that the positive ROAT appeared early during the investigative period. CONCLUSIONS: The algorithm used in this study was not substantiated in this ROAT set-up. The stronger the patch test reactivity the more likely was a positive ROAT and the more likely it was that the positive ROAT appeared early during the application period. What's already known about this topic? To the best of our knowledge, a scientifically designed and conducted repeated open application test (ROAT) has never been performed before to validate a diagnosis of allergic contact dermatitis partly based on a questionnaire. What does this study add? This is the largest controlled, randomized and blinded ROAT performed to date. Higher patch test reactivity to fragrance mix I indicated a greater likelihood of a positive ROAT. What are the clinical implications of this work? Further refinement of the questions is required in order to diagnose allergic contact dermatitis from fragrances based on a questionnaire.

BACKGROUND: A long-term prospective observational safety study is essential to characterize fully the safety profile of systemic immunomodulating therapies for patients with atopic eczema. The TREatment of ATopic eczema (TREAT) Registry Taskforce offers a large platform to conduct such research using national registries that collect the same data using a predefined core dataset. OBJECTIVES: To present a protocol for a safety study comparing dupilumab with other systemic immunomodulating therapies in children and adults with moderate-to-severe atopic eczema, to assess the long-term safety risk of these therapies in a routine clinical care setting. METHODS: We describe a registry-embedded international observational prospective cohort study. Adult and paediatric patients who start treatment with dupilumab or another systemic immunomodulating agent for their atopic eczema will be included. The primary end point is the incidence of malignancies (excluding nonmelanoma skin cancer) compared between the treatment groups. Secondary end points include other serious adverse events and adverse events of special interest, such as eye disorders and eosinophilia. CONCLUSIONS: This protocol delineates a safety study for dupilumab in adult and paediatric patients with atopic eczema, using a standardized methodological approach across several national registries. The protocol could also be used for other novel systemic immunomodulating therapies, and could provide licensing and reimbursement authorities, pharmaceutical companies and clinicians with safety evidence from a routine clinical care setting. What's already known about this topic? There is a need for long-term data on the safety of systemic immunomodulating therapies in patients with atopic eczema. Regulatory bodies, such as the European Medicines Agency, increasingly stipulate the collection of such data as part of the licensing agreement for new treatments, to assess the new agent's long-term safety profile against established therapies. Large numbers of patients with a long duration of follow-up are necessary in order to detect rare events like malignancies. What does this study add? The TREAT Registry Taskforce offers a platform to conduct such research with a network of multiple national atopic eczema research registries. We present a protocol for an investigator-initiated multicentre safety study comparing dupilumab with other systemic immunomodulating therapies in adults and subsequently adolescents and children with moderate-to-severe atopic eczema. This protocol can be used as a framework for similar studies for other novel systemic immunomodulating therapies across both adult and paediatric populations.

Since the first case of 'pneumonia of unknown aetiology' was diagnosed at the Wuhan Jinyintan Hospital in China on 30 December 2019, what was recognized thereafter as 'severe acute respiratory syndrome coronavirus 2' (SARS-CoV-2) has spread over the four continents, causing the respiratory manifestations of coronavirus disease-19 (COVID-19) and satisfying the epidemiological criteria for a label of 'pandemic'. The ongoing SARS-CoV-2 pandemic is having a huge impact on dermatological practice including the marked reduction of face-to-face consultations in favour of teledermatology, the uncertainties concerning the outcome of COVID-19 infection in patients with common inflammatory disorders such as psoriasis or atopic dermatitis receiving immunosuppressive/immunomodulating systemic therapies; the direct involvement of dermatologists in COVID-19 care for patient assistance and new research needs to be addressed. It is not known yet if skin lesions and derangement of the skin barrier could make it easier for SARS-CoV-2 to transmit via indirect contact; it remains to be defined if specific mucosal or skin lesions are associated with SARS-CoV-2 infection, although some unpublished observations indicate the occurrence of a transient varicelliform exanthema during the early phase of the infection. SARS-CoV-2 is a new pathogen for humans that is highly contagious, can spread quickly, and is capable of causing enormous health, economic and societal impacts in any setting. The consequences may continue long after the pandemic resolves, and new management modalities for dermatology may originate from the COVID-19 disaster. Learning from experience may help to cope with future major societal changes.

On 11 March 2020, the World Health Organization (WHO) has declared the novel coronavirus disease (COVID-19) a global pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus). A consistent number of case reports and clinical series have been already published describing a complex spectrum of skin manifestations associated with the SARS-CoV-2 infection. We carried out a review of the English-language literature up to 20 May 2020, reporting original cases or case series of the cutaneous manifestations of SARS-CoV-2 virus infection. The following databases were consulted: PubMed, Embase, Google Scholar and ResearchGate. The search of papers was conducted by using the key term 'COVID-19' or 'SARS-CoV-2' or 'coronavirus' combined with each of the following: 'skin', 'cutaneous', 'dermatologic' or 'dermatology', 'manifestation', 'lesions', or 'rash'. The patterns of dermatological manifestations associated with SARS-CoV-2 infection could be classified into four categories: exanthema (varicella-like, papulo-vesicular and morbilliform rash), vascular (chilblain-like, purpuric/petechial and livedoid lesions), urticarial and acro-papular eruption. Lastly, other skin manifestations to be considered are the cutaneous adverse reactions to the drugs prescribed for the treatment of COVID-19. Whether SARS-CoV-2 infection can directly cause a worsening of chronic inflammatory diseases such as psoriasis or atopic dermatitis remains to be determined. Dermatology's outlook in the COVID-19 pandemic is multidimensional.

BACKGROUND: The incidence of hidradenitis suppurativa (HS) is still not fully established with only a few studies reporting its estimates. Prevalence estimates range from 5:10 000 to 4:100. These extremely large variations could be explained by a combination of factors, including different selection procedures, different diagnostic criteria, and variations in the sex and age distribution of the examined samples. OBJECTIVES: To analyze variations between two consecutive Italian Registries on HS. METHODS: Data obtained from the second Italian Registry on HS, named 'Italian Registry Hidradenitis Suppurativa (IRHIS) Project 2', are compared to the previous first Italian registry on HS. RESULTS: Data on 944 patients are reported. The more relevant aspects that characterize IRHIS 2 project, in comparison with the previous first Italian Registry on HS, are as follows: (i) the total number of patients, about fourfold higher; (ii) a more uniform national geographic distribution of the patient population; (iii) a larger number of dermatology units involved; (iv) a larger number of items considered in the data collection; (v) 6 years of difference between the onset of the two registries (2009-2013 vs. 2015-2019). Comparing data of the two registries, there are no statistically significant differences in terms of age at the time of the visit, gender, BMI, smoking habits, age at onset and age at first diagnosis by physician. Interestingly, the mean Sartorius score in the IRHIS project 2 (58.8) was significantly lower compared to the first Italian Registry (78.4). CONCLUSIONS: The importance of the registries, at both national and international levels, in collecting useful real-life data is confirmed by these two Italian projects.

BACKGROUND: Several treatment options are currently available for the treatment of psoriasis. OBJECTIVE: To explore the main associations between patients' characteristics and systemic treatments prescribed for psoriasis in a large group of patients observed in real-life clinical practice. METHODS: This was a retrospective analysis of baseline data collected within the Swiss Dermatology Network for Targeted Therapies registry in Switzerland between March 2011 and December 2017. Semantic map analysis was used in order to capture the best associations between variables taking into account other covariates in the system. RESULTS: A total of 549 patients (mean age 46.7 ± 14.7 years) were included in the analysis. Conventional therapies such as retinoids and methotrexate were associated with no previous systemic therapies for psoriasis, a moderate quality of life (QoL) at therapy onset and older age (≥60 years). Fumaric acid derivatives were associated with mild psoriasis (psoriasis area severity index < 10) and long disease duration (≥20 years). On the other side, cyclosporine and psoralen and ultraviolet A/ultraviolet B treatments were linked to a more severe condition, including impaired QoL, hospitalization and inability to work. Regarding biological therapies, both infliximab and adalimumab were connected to the presence of psoriatic arthritis, severe disease condition and other comorbidities, including chronic liver or kidney diseases and tuberculosis. Etanercept, ustekinumab and secukinumab were all connected to a complex history of previous systemic treatments for psoriasis, moderate disease condition, overweight and university education. CONCLUSIONS: The analysis shows multifaceted associations between patients' characteristics, comorbidities, disease severity and systemic treatments prescribed for psoriasis. In particular, our semantic map indicates that comorbidities play a central role in decision-making of systemic treatments usage for psoriasis. Future studies should further investigate specific connections emerging from our data.

BACKGROUND: There is a lack of prevalence data on skin diseases in the general adult population; most studies have been carried out in small, national or consecutive clinical samples. OBJECTIVES: To determine the prevalence of common skin disease in the general European population and to assess differences in the characteristics of treatment between countries. METHODS: A random sample consisting of 12 377 participants aged 18-74 years was drawn from the general population of five European countries (Germany, Italy, the Netherlands, Portugal and Sweden). This was a cross-sectional study and all participants were interviewed using a standardized questionnaire that assessed the occurrence of 10 common skin diseases during lifetime, past year and past month. If a skin disease was reported, we additionally assessed who performed the diagnosis and treatment, and whether drugs had been prescribed. RESULTS: The most common skin disease was warts (41·3%), followed by acne (19·2%) and contact dermatitis (15·0%). In general, women were more often affected by skin diseases compared with men; only skin cancer had a slightly higher prevalence in men. The prevalence of skin diseases in northern countries (Germany, the Netherlands and Sweden) was generally higher than in the southern countries (Italy and Portugal). In the Netherlands the treatment of skin diseases was less often performed by a dermatologist compared with the other countries. CONCLUSIONS: The prevalence estimates reported in this study are derived from a representative sample of the general population. Data assessment was performed comprehensively across countries, thus country-specific prevalence estimates are comparable.

BACKGROUND: Psoriasis is a chronic, immune-mediated disease, characterized by symptoms that include itching and skin pain and is often associated with comorbidities. Patients have a substantial detriment to quality of life (QoL) and work productivity with associated cost burden. OBJECTIVES: To investigate the incremental burden of comorbidities, itch and affected body areas among systemic eligible patients with psoriasis, using a multinational survey of dermatologists and their patients with psoriasis. METHODS: Multinational data from the Growth from Knowledge (GfK) Disease Atlas Global Real-World Evidence program were used. Eligible patients were identified as those who were currently having or had ever had moderate-to-severe psoriasis, and must have been receiving prescription treatments at the time of the survey. Multivariable regression analyses were conducted to assess the incremental burden among psoriasis patients with physical and psychological comorbidities, itch and affected visible and sensitive body areas vs. psoriasis patients without these conditions, respectively. RESULTS: The study enrolled 3821 patients with psoriasis, from nine countries, with an average Psoriasis Area and Severity Index score of 6·4. The presence of comorbidities was associated with a significant increase in the likelihood of skin pain, lower QoL, greater work impairment and increased usage of medical resources (except in psoriasis patients with obesity and type 2 diabetes). Psoriasis patients suffering from itch and those with visible and sensitive affected body areas also had impaired QoL vs. those without these conditions. CONCLUSIONS: Psoriasis patients with physical and psychological comorbidities, itch and affected visible and sensitive body areas had lower QoL and greater work impairment compared to those without these conditions.

BACKGROUND: Hand eczema has a high incidence and prevalence and has a negative impact on both physical and psychological well-being, with the risk of persistence as a chronic condition. Epidemiological studies on hand eczema provided mainly descriptive and risk analyses, but pattern analyses of variables associated with hand eczema, in particular chronic hand eczema, have not been explored to date. OBJECTIVES: To investigate and display the semantics of associations between variables of hand eczema obtained from the Swiss and German registries of chronic hand eczema (CARPE) to dissect patterns and novel links. METHODS: This was a cross-sectional study on selected variables from the CARPE registries. Associations between variables were analysed by means of an autoassociative system. A semantic connectivity map was generated by using a maximum spanning tree algorithm. RESULTS: Baseline datasets of 1466 patients with chronic hand eczema (Switzerland: 199; Germany: 1267) were analysed. Occupational exposure had the highest impact in the total and country cohorts. We identified two areas of exposure linked to corresponding occupations that clearly demarcated the sexes. CONCLUSIONS: This study, using semantic connectivity as a novel method of data analysis, reveals the complexity of features characterizing chronic hand eczema as well as novel association patterns that deserve further investigation.

BACKGROUND: Cancer risk following long-term exposure to systemic immunomodulatory therapies in patients with psoriasis is possible. OBJECTIVES: To assess a dose-response relationship between cumulative length of exposure to biological therapy and risk of cancer. METHODS: Four national studies (a healthcare database from Israel, and prospective cohorts form Italy, Spain and the U.K. and Republic of Ireland) collaborating through Psonet (European Registry of Psoriasis) participated in these nested case-control studies, including nearly 60 000 person-years of observation. 'Cases' were patients who developed an incident cancer. Patients with previous cancers and benign or in situ tumours were excluded. Four cancer-free controls were matched to each case on year of birth, sex, geographic area and registration year. Follow-up for controls was censored at the date of cancer diagnosis for the matched case. Conditional logistic regression was performed by each registry. Results were pooled using random-effects meta-analysis. RESULTS: A total of 728 cases and 2671 controls were identified. After matching, differences between cases and controls were present for the Charlson Comorbidity Index in all three registries, and in the prevalence of previous exposure to psoralen-ultraviolet A and smoking (the British Association of Dermatologists Biologic Interventions Register only). The risk of first cancers was not significantly associated with cumulative exposure to biologics (adjusted odds ratio per year of exposure 1·02, 95% confidence interval 0·92-1·13). Results were similar if squamous and basal cell carcinomas were included in the outcome. CONCLUSIONS: Cumulative length of exposure to biological therapies in patients with psoriasis in real-world clinical practice does not appear to be linked to a higher risk of cancer after several years of use.

BACKGROUND: The variables affecting participants' satisfaction with a scientific conference in dermatology have not been systematically assessed. The European Academy of Dermatology and Venereology (EADV) has collected a huge number of questionnaires related to sessions' and speakers' evaluation over the years. The critical analysis of satisfaction's score is important and helpful for continuous improvement of the scientific programming. OBJECTIVE: To identify factors that positively or negatively affect sessions' and speakers' scoring in the largest European congress of dermatology. METHODS: This was a retrospective analysis of all sessions' evaluation forms collected between 2009 and 2015 during seven consecutive EADV congresses. A predictive model for sessions' and another for speakers' score evaluation were built based on multivariate linear regression. RESULTS: Overall, 4964 speakers and 1022 sessions were evaluated. Topics more positively associated with total sessions' scoring were as follows: dermoscopy, neutrophilic diseases and hidradenitis suppurativa. Conversely, types of sessions which considerably negatively associated with total sessions' scoring included short thematic presentations and free communications. Furthermore, types of sessions which were more positively associated with high total speakers' scoring consisted of focus sessions and plenary lectures, whereas the most appreciated topics encompassed dermoscopy, screening programs, melanocytic naevi, panniculitis, organ transplanted and immunosuppressed patients, neutrophilic diseases, dermatopathology and history of dermatology. Finally, short thematic presentations, free communications and guidelines session showed overall poor scores. CONCLUSION: Focused and specialized topics are more prone to capture attention of participants when compared to sessions of heterogeneous content. Quite surprisingly, a practice-oriented topics such as guidelines, did not achieve a high score. Our findings provide new knowledge about components, which increase the level of satisfaction of participants and should facilitate the programming of attractive scientific congresses associated with increased training satisfaction.

BACKGROUND: Hidradenitis Suppurativa (HS) is a chronic, highly debilitating disease. Few questionnaires have been developed to identify potential HS cases based on simple questions. A visual representation may help in characterising these lesions. OBJECTIVE: To develop and validate a visually assisted questionnaire for HS detection. METHODS: This was an observational diagnostic study on a series of patients with a first diagnosis of HS and a corresponding series of age and gender-matched controls consecutively observed in two Italian centres. The questionnaire was developed based on a critical appraisal of the relevant literature and on expert consensus. Measures of accuracy and reproducibility were assessed. RESULTS: 57 patients with HS and 57 controls were included in the study (mean age 32.9 ± 12.3 years). Based on at least one affirmative answer to the proposed questionnaire items, the accuracy was 95.6%, with a sensitivity of 98.2% and a specificity of 93.0%. Reproducibility was almost perfect on all the tested items (Cohen's kappa ≥ 0.85). LIMITATIONS: The questionnaire was tested only in experimental conditions. CONCLUSION: The questionnaire could be a useful tool for HS screening in the general population. Further studies are needed to confirm its performance in a real-world setting.

Fumaric acid esters (FAEs) are a group of small molecules that were first investigated for the treatment of psoriasis in 1959. The first fumarate-based drug - Fumaderm® - was approved in Germany in 1994 for severe psoriasis and then in 2008, the label was expanded to include moderate psoriasis. Fumaderm is a combination of different FAEs: dimethyl fumarate (DMF), which is regarded as the main active component, plus calcium, magnesium and zinc salts of monoethyl fumarate (MEF). FAEs are the most frequently used first-line systemic psoriasis treatment in Germany, with an overall treatment experience comprising more than 220 000 patient-years. FAEs have demonstrated good, sustained clinical efficacy with an acceptable safety profile for the long-term treatment of patients with moderate-to-severe psoriasis. Indeed, the European S3-Guideline on the systemic treatment of Psoriasis vulgaris recommends FAEs for induction and long-term treatment. Until recently, FAEs were only licensed (for the psoriasis indication) in Germany, but were imported to many other European countries, such as The Netherlands, UK, Ireland, Austria and Italy, for the treatment of psoriasis. In 2017, the European Medicines Agency (EMA) approved Skilarence® , a new oral formulation of DMF, for the treatment of adult patients with moderate-to-severe chronic plaque psoriasis in need of systemic therapy. Skilarence only contains DMF and is the first FAE for the treatment of psoriasis that has been approved by the EMA. This approval has given rise to a new oral treatment option for patients with moderate-to-severe plaque psoriasis across Europe. Here, we report the results of an expert meeting which was convened to deliver clinician-agreed consensus and real-world guidance on the clinical use of DMF in moderate-to-severe chronic plaque psoriasis. Guidance on appropriate patient selection, DMF dosage considerations, monitoring and side-effect management is offered based upon available evidence and collective real-world clinical experience.

BACKGROUND: Psoriasis is a chronic immune-mediated inflammatory disease, which often requires lifelong treatment. A strong partnership between the patient and healthcare practitioners should help to achieve effective treatment outcomes. OBJECTIVE: To assess concordance of views between patients with psoriasis and their treating dermatologists relative to psoriasis severity, presence of symptoms and satisfaction with disease control achieved. METHODS: We used data from the Growth from Knowledge (GfK) Disease Atlas real-world evidence program, a syndicated, retrospective, cross-sectional survey among dermatologists and their systemic therapy eligible patients with psoriasis, conducted across nine countries. Concordance was measured through patients and their dermatologist's identical answers to the same survey questions. Concordance was evaluated using percentage agreement between dermatologists and their patients, and Cohen's kappa (κ) statistic. The level of concordance was defined as 'none' (κ ≤ 0), 'none to slight' (0.01-0.20), 'fair' (0.21-0.40), 'moderate' (0.41-0.60), 'substantial' (0.61-0.80) and 'almost perfect' (>0.8). The analysis was conducted for the overall population and for each participating country. RESULTS: Overall, 524 dermatologists and 3821 patients with psoriasis were included in the survey. Concordance of patient and dermatologist perceptions of psoriasis severity was fair both at diagnosis, and at the time of the survey (61% agreement, κ = 0.326 and 55% agreement, κ = 0.370, respectively). Higher levels of concordance were reported when patients assessed their psoriasis as moderate-to-severe (using Investigator's Global Assessment/Physician's Global Assessment [IGA/PGA] 5-point scale of 3 or 4). Concordance regarding symptoms ranged from fair to moderate (κ = 0.241-0.575). Satisfaction with psoriasis control was fair (39% agreement, κ = 0.213). Results showed different patterns of concordance across the participating countries although a low concordance was observed on the satisfaction with psoriasis control in all of them. CONCLUSION: Results from this multinational real-world survey indicate different perceptions between patients with psoriasis and their dermatologist with respect to psoriasis severity, symptoms and disease control.

BACKGROUND: Biologics have greatly improved psoriasis management. However, primary and secondary non-response to treatment requires innovative strategies to optimize outcomes. OBJECTIVE: To describe the use of combined treatment of biologics with conventional systemic agents or phototherapy in daily clinical practice. METHODS: We collected data on frequency of use, demographics, treatment characteristics and drug survival of biologics combined with conventional systemic agents or phototherapy in five PSONET registries. RESULTS: Of 9922 biologic treatment cycles, 982 (9.9%) were identified as combination treatment. 72.9% of treatment cycles concerned concomitant use of methotrexate, 25.3% concerned concomitant UVB therapy, acitretin or cyclosporin and 1.8% concerned combined treatment with PUVA, fumaric acids or a second biologic. Substantial variation was detected in type and frequency of combination treatments prescribed across registries. Patients initiated on combined treatment had generally severe disease and were affected with psoriasis for many years. The extent to which patients had been priory treated with biologic monotherapy and the proportion of patients affected with psoriatic arthritis differed between registries. Survival rates for etanercept, adalimumab, infliximab and ustekinumab with methotrexate ranged between 43 and 92%, 28 and 83%, 65 and 87% and 53 and 77%, respectively, across registries after one year with no consistent superior survival for a particular biologic. Longest survival on a biologic combined with methotrexate, acitretin or cyclosporin was 103, 78 and 34 months, respectively. CONCLUSION: Methotrexate was the most commonly used concomitant treatment for patients on a biologic. Wide geographical variations in treatment selection and persistence of combination treatment exist. Data derived from ongoing studies may help to determine whether combined treatment is superior to biologic monotherapy.
