Happiness across the borders-A cross-sectional study among patients with psoriasis and atopic dermatitis in Europe.

BACKGROUND: Dermatological research has traditionally concentrated on evaluating mental comorbidities, neglecting positive concepts like happiness. Initial studies indicate that psoriasis and atopic dermatitis (AD) impair the happiness of those affected. Considering global happiness variations, this study aimed to explore the disease- and country-specific differences in disease-related quality of life and happiness, and potential influential factors on heuristic happiness among psoriasis and AD patients in Europe. METHODS: A cross-sectional multicentre study was conducted in dermatology departments of university-affiliated hospitals in eight European countries (Austria, Germany, Italy, Malta, Poland, Portugal, Romania and Ukraine) between October 2021 and February 2023. Adult psoriasis and AD patients completed a standardized questionnaire in their native languages, providing data on demographics, disease-related characteristics, disease-related quality of life (Dermatology Life Quality Index, DLQI), heuristic happiness, positive affect (PA), negative affect (NA) and satisfaction with life (SWL). Descriptive analysis and quantile regression were performed. RESULTS: Between psoriasis (n = 723) and AD (n = 316) patients almost no differences were observed in happiness, SWL and NA, except for DLQI and small differences in PA, with AD patients reporting greater impact than psoriasis patients. Country-wise variation emerged in DLQI, heuristic happiness, PA, NA and SWL with Austrian patients displaying the highest levels of happiness, satisfaction and positivity, coupled with higher treatment care and lower disease severity. Quantile regression revealed varying coefficients for predictor variables across quantiles, indicating, for example positive effects on heuristic happiness associated with current or previous receipt of systemic therapies at different quantiles. CONCLUSION: This study shows notable happiness differences across European countries and significant disease-related variations, particularly with AD patients being more impaired than psoriasis patients. The findings highlight the need for equality in treatment access and support the development of targeted positive psychological interventions to enhance happiness considering country-specific distinctions in future research and health policies for psoriasis and AD patients.

Moderate-to-severe atopic dermatitis in adolescents treated with dupilumab: A multicentre Italian real-world experience.

BACKGROUND: Moderate-to-severe atopic dermatitis (AD) in the adolescence is a high burden disease, and its treatment can be very challenging due to paucity of approved systemic drugs for this age and their side-effects. Dupilumab was recently approved for treatment of adolescent AD. OBJECTIVES: A multicentre, prospective, real-world study on the effectiveness and safety of dupilumab in adolescents (aged from ≥12 to <18 years) with moderate-to-severe AD was conducted. The main AD clinical phenotypes were also examined. METHODS: Data of adolescents with moderate-to-severe AD treated with dupilumab at label dosage for 16 weeks were collected. Treatment outcome was assessed by EASI, NRS itch, NRS sleep loss and CDLQI scores at baseline and after 16 weeks of treatment. The clinical scores were also evaluated according to clinical phenotypes. RESULTS: One hundred and thirty-nine adolescents were enrolled in the study. Flexural eczema and head and neck eczema were the most frequent clinical phenotypes, followed by hand eczema and portrait-like dermatitis. Coexistence of more than 1 phenotype was documented in 126/139 (88.5%) adolescents. Three patients (2.1%) contracted asymptomatic SARS-CoV-2 infection and 1 of the discontinued dupilumab treatment before the target treatment period. A significant improvement in EASI, NRS itch, NRS sleep loss and CDLQI was observed after 16 weeks of treatment with dupilumab. This outcome was better than that observed in clinical trials. Dupilumab resulted effective in all AD phenotypes, especially in diffuse eczema. Twenty-eight (20.1%) patients reported adverse events, conjunctivitis and flushing being the most frequent. None of patients discontinued dupilumab due to adverse event. CONCLUSIONS: Dupilumab in adolescent AD showed excellent effectiveness at week 16 with consistent improvement of all clinical scores. Moreover, dupilumab showed a good safety profile also in this COVID-19 pandemic era.

Patch test informed consent form: position statement by European Academy of Dermatology and Venereology Task Force on Contact Dermatitis.

BACKGROUND: To our knowledge, an international consensus is lacking regarding the development of an adequate informed consent form for a patch test (PT) and the information that should be included in such document. OBJECTIVES: The aim of the study was to reach a consensus on the specific points that need to be addressed in a PT consent form. METHODS: A Delphi survey, comprising 2 rounds and 1 final discussion, was used to gather and analyse data, which was conducted over the Internet. Each statement that reached a consensus with the respondents (9 expert dermatologists from Europe) was defined as a median consensus score (MED) of ≥7 and agreement among panelists as an interquartile range (IQR) of ≤3. All study participants were members of the EADV task force on contact dermatitis. RESULTS: The expert panel addressed several topics that should be included in an informed consent form for a PT: introduction, preparation for PT, testing procedure, allowed activities, adverse events and additional authorizations. CONCLUSIONS: Our results assess recommendations regarding points to be contained in an informed consent form for a PR. Future actions towards standardization and harmonization of this specific consent form are needed.

Position statement: The need for EU legislation to require disclosure and labelling of the composition of medical devices.

BACKGROUND: In recent years, skin reactions secondary to the use of medical devices (MD), such as allergic contact dermatitis have increasingly been observed (e.g. to continuous blood sugar monitoring systems, insulin pumps, wound dressings, medical gloves, etc.): this is regarded as a developing epidemic. Lack of labelling of the composition of MD, as well as frequent lack of cooperation of manufacturers to disclose this relevant information, even when contacted by the clinician for the individual case of an established adverse reaction, significantly impede patient care. OBJECTIVES: To advocate for full ingredient labelling in the implementation of EU regulation for MD. METHODS: This position paper reviews the scientific literature, the current regulatory framework adopted for MD to date, and the likely impact, including some costs data in case of the absence of such labelling. RESULTS: Efforts made by several scientific teams, who are trying to identify the culprit of such adverse effects, either via asking for cooperation from companies, or using costly chemical analyses of MD, can only partly, and with considerable delay, compensate for the absence of meaningful information on the composition of MD; hence, patient management is compromised. Indeed, without knowing the chemical substances present, physicians are unable to inform patients about which substances they should avoid, and which alternative MD may be suitable/tolerated. CONCLUSION: There is an urgent need for full and accurate labelling of the chemical composition of MD in contact with the human body.

Certolizumab for the treatment of psoriasis and psoriatic arthritis: a real-world multicentre Italian study.

BACKGROUND: Certolizumab, a pegylated tumour necrosis factor-α inhibitor, reduced disease activity in randomized trials of patients with psoriasis and psoriatic arthritis. Real-life data are missing. OBJECTIVE: To confirm the effectiveness and safety of certolizumab in patients with psoriasis and psoriatic arthritis in routine clinical practice. METHODS: In this retrospective study involving 11 Italian sites, patients with psoriasis and psoriatic arthritis received subcutaneous certolizumab (400 mg loading dose at 0, 2 and 4 weeks, followed by 200 mg every 2 weeks) for up to 52 weeks. Primary outcomes included mean change from baseline in Psoriasis Area and Severity Index (PASI) and modified Nail Psoriasis Severity Index (mNAPSI) scores, and the proportion of patients achieving a 75%, 90% or 100% reduction in PASI score. Other endpoints included Disease Activity Score computed on 44 joints correlated with the erythrocyte sedimentation rate during the first hour (DAS44-ESR), Tender Joint Count (TJC), Swollen Joint Count (SJC), pain [visual analogue scale (VAS) score], inflammatory markers and quality of life (QOL). RESULTS: In the study were enrolled 153 patients (mean age: 55 years). Certolizumab reduced the mean PASI score from baseline by 4.45, 6.30 and 7.58 at weeks 12, 24 and 52, respectively (P < 0.001 for all). At weeks 24 and 52, 69.6% and 83.3% of patients had a PASI score ≤3. DAS44-ESR, TJC, SJC and mNAPSI scores, and pain VAS were also all significantly improved from baseline at each time point. C-reactive protein levels decreased during treatment, being significant at week 24. On multivariate analysis, psoriasis duration, baseline PASI, mNAPSI and pain VAS scores were found to be predictive of the improvement in PASI score at week 12. CONCLUSION: Certolizumab displayed also in the real-life encouraging results in both psoriasis and psoriatic arthritis patients.

A new T helper 17 cytokine in hidradenitis suppurativa: antimicrobial and proinflammatory role of interleukin-26.

BACKGROUND: Interleukin (IL)-26 is a signature T helper 17 cytokine described as a proinflammatory and antimicrobial mediator. So far, IL-26 has been reported in several immune-mediated inflammatory diseases, but its involvement in inflammatory skin disorders is poorly known. OBJECTIVES: To investigate the role of IL-26 in hidradenitis suppurativa (HS), through its involvement in antimicrobial activity. METHODS: IL-26 was assessed in patients with HS through gene expression and protein analysis at skin and circulating levels. Ex vivo HS organ skin cultures, together with IL-26 antibody treatment, were performed to determine the IL-26 activity. Peripheral blood mononuclear cells (PBMCs) from patients with HS and healthy controls were either silenced or not with IL-26 small interfering (si)RNA in order to measure its antimicrobial, cytotoxic and phagocytic activities against Staphylococcus aureus. RESULTS: Firstly, we observed that IL-26 is able to modulate the proinflammatory response at the immune cell level. IL-26 was increased in the plasma of patients with HS compared with healthy controls. Subsequently, we explored the bactericidal, cytotoxic and phagocytic activities of PBMCs against S. aureus in patients with HS and healthy controls. These activities were lower in patients with HS than in controls. Remarkably, the killing activities were reduced when healthy control PBMCs were transfected with IL-26 siRNA. However, the transfection did not affect the killing activity of HS PBMCs, supporting the idea that IL-26 lacks efficacy in HS. CONCLUSIONS: Our findings suggest that infection susceptibility in HS might be related to IL-26. Although the role of bacteria remains controversial in HS, this paper supports that there is a defect of antimicrobial response in these patients. What's already known about this topic? Interleukin (IL)-26 is a T helper 17 cytokine described as an antimicrobial and proinflammatory mediator. IL-26 has been reported in immune-mediated inflammatory diseases, but its involvement in inflammatory skin disorders remains unclear. Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder characterized by deficiency of IL-20 and IL-22 (a close homologue of IL-26), which causes antimicrobial peptide pauperization leading to severe and recurrent skin infections. What does this study add? IL-26 plasma levels are higher in patients with HS than in healthy control individuals. The antimicrobial activity of IL-26 might be ineffective in patients with HS. What is the translational message? Cutaneous antimicrobial incompetence in HS could be related to IL-26.

Psoriasis and skin pain: real-life effectiveness of calcipotriol plus betamethasone dipropionate in aerosol foam formulation.

BACKGROUND/OBJECTIVE: Although 40% of psoriasis patients reported skin pain, this symptom is often underestimated. A new formula of calcipotriol plus betamethasone dipropionate (Cal/BD) has been recently approved for psoriasis treatment. Therefore, we aimed to evaluate the efficacy of Cal/BD aerosol foam on skin pain of patients with plaque psoriasis. METHODS: A real-life 4-week prospective, open study on Cal/BD aerosol foam (not compared to vehicle or emollient cream) was performed in adult psoriasis patients attending three Dermatology units located in Campania region, Italy, between March and October 2018. Inclusion criteria were a history of skin pain over the last week and psoriatic involvement of the palmar area. Before (t0) and after a course of once daily application of Cal/BD aerosol foam for 4 weeks (t1), the following items were evaluated: Psoriasis Area and Severity Index (PASI), Physician Global Assessment (PGA) index of target plaque on palmar region, subjective skin pain features through Pain Qualities Assessment Scale questionnaire and skin pain threshold measured by pressure digital algometer at palmar psoriatic plaques. RESULTS: Seventy-five patients (43 male, mean age of 43.2 years) were enrolled. After 4 weeks of therapy with Cal/BD aerosol foam, a significant improvement in both PASI (mean: 6.5 ± 2.1 at t0 vs. 2.3 ± 1.6 at t1) and palmar plaques PGA (mean: 3.6 at t0 vs. 1.7 at t1) was observed (P < 0.001). The mean intensity score of skin pain decreased from 7.6 to 1.3 (P < 0.001); among skin pain qualities, intense, sensible, aching and unpleasant showed the highest rate of reduction (t0-t1: 6.3, 6.3, 6.1 and 5.8, respectively). Pain threshold of palmar skin lesions increased at t1. CONCLUSIONS: Our real-life study suggested that Cal/BD aerosol foam may represent a valid topical anti-psoriatic treatment, not only improving skin lesions, but also relieving cutaneous pain, thus contributing to ameliorate patients' quality of life.

The role of the dermatologist in the immune-mediated/allergic diseases - position statement of the EADV task force on contact dermatitis, EADV task force on occupational skin diseases, UEMS-EBDV subcommission allergology and European Dermatology Forum.

BACKGROUND: The members of the Task Force on Contact Dermatitis and the Task Force on Occupational Dermatoses of the European Academy of Dermatology and Venereology (EADV), of the European Dermatology Forum (EDF), and the members of the UEMS Section of Dermatology-Venereology (UEMS-EBDV) we want to vindicate the fundamental role that the specialist in Dermatology has in the diagnosis and management of Immuno-mediated /allergic Diseases. OBJECTIVE: In disagreement with the blueprint paper of the UEMS section of Allergology (2013), in which dermatologists are excluded from one of their core activities it was decided to write this consensus paper. DISCUSSION: The skin occupies a crucial place in the broad spectrum of allergic diseases; there is no other organ with such a multitude of different clinical conditions mediated by so many pathogenetic immune mechanisms. Subsequently, dermatologists play a fundamental role in the management of immune-mediated diseases including among others contact dermatitis, atopic dermatitis, urticaria and angioedema or cutaneous adverse drug, food and arthropod reactions. The essential role of dermatology in the diagnostic, therapeutic and preventive management of immune mediated /allergic diseases which is crucial for patient management is justified from both the academic and professional point of view. CONCLUSION: Based on the best care of the patient with cutaneous immune allergic disease a multidisciplinary approach is desirable and the dermatologist has a pivotal role in patient management. Be so good and no one will not ignore you, dermatologist. Ideally Dermatology should be governed according the following Henry Ford statement: "Arriving together is the beginning; keeping together is progress; working together is success."

Rational ideation and empiric validation of an innovative digital dermographic tester.

BACKGROUND: Dermographism is a condition characterized by a weal response to a combination of pressure and traction on skin surface, and its diagnosis is based on medical history, clinical criteria and provocation test. The Dermographic Tester® , a pen-sized tool containing a spring-loaded blunt tip, is the most widely used instrument for the provocation test, and it exerts increasing pressures on the skin surface according to an arbitrary units (AU) scale. Analysing the mechanism of function and trying to convert the AUs to SI units (g/mm2 ), we found that this instrument had some defects and limits that would compromise a true and repeatable quantification of the weal response threshold. Consequently, we decided to develop a new instrument, the Digital Dermographic Tester (DDT), which is engineered with an inside force sensor to implement features lacking in the current tools, in the hope of enhancing the precision of the provocation test. AIM: To validate the effectiveness and accuracy of the DDT. METHODS: We tested the DDT on 213 participants purposely sampled to obtain three groups, each with a different pattern of reaction to mechanical stimuli. Based on anamnestic, diagnostic and symptomatic criteria, patients were divided into dermographic urticaria (DU), spontaneous urticaria (SU) and healthy control (HC) groups. The DDT was used to apply 12 levels of pressure to the skin surface, and a frequency distribution of positive reactions was displayed for each group. RESULTS: A force of 36-40 g/mm2 appropriately differentiated physiological from pathological conditions with high sensitivity and specificity. CONCLUSIONS: The DDT was found to be capable of differentiating patients with DU patients from those with SU and from HCs, and was able to precisely identify the weal elicitation threshold.

Polymorphic light eruption and IL-1 family members: any difference with allergic contact dermatitis?

Polymorphic light eruption (PLE) is described as a delayed-type hypersensitivity reaction (DTHR) toward a de novo light-induced antigen, yet to be identified. In effect, the inflammatory pathways of PLE and allergic contact dermatitis (ACD) share common patterns in terms of the mediators involved from the innate and adaptive immune system participating in the DTHR. As we have previously highlighted the role of interleukin (IL)-1 family members in ACD, we hypothesised that the same mediators could have similar functions in PLE. Our research aimed to assess the expression of certain IL-1family members in PLE patients vs. controls, and to compare it with ACD. The study population comprised 17 patients with PLE, 5 affected by ACD and 10 healthy controls in the same age range. Lesional and healthy skin samples were collected respectively from patients and donors. IL-36α, IL-36ß, IL-36γ, IL-36 receptor antagonist (Ra), IL-1ß, IL-33 gene and protein expressions were evaluated through RT-PCR and immunohistochemistry. Circulating proteins in the PLE patients were analysed by using western blot. The IL-36γ gene expression was significantly increased in PLE lesions compared to that in healthy controls and ACD lesions (***p < 0.001; ##p < 0.01 respectively), whereas the other analyzed ILs were more expressed in ACD. Immunohistochemical analysis revealed that IL-36α and IL-36γ protein levels were increased in PLE lesions compared to those of the healthy samples (***p < 0.001). Furthermore the IL-36γ plasma level was increased in PLE patients vs. controls (*p < 0.05). Our findings indicate that the IL-1 family pro-inflammatory members are increased in PLE with distinct differences from those in ACD, in particular with regard to IL-36γ mRNA regulation. Their role as activators of the local, and perhaps systemic, immune response, or as inhibitors of the immune tolerance machinery, needs further investigation.

European Surveillance System on Contact Allergies (ESSCA): results with the European baseline series, 2013/14.

BACKGROUND: Contact allergy is a common condition and can severely interfere with daily life or professional activities. Due to changes in exposures, such as introduction of new substances, new products or formulations and regulatory intervention, the spectrum of contact sensitization changes. OBJECTIVE: To evaluate the current spectrum of contact allergy to allergens present in the European baseline series (EBS) across Europe. METHODS: Retrospective analysis of data collected by the European Surveillance System on Contact Allergies (ESSCA, www.essca-dc.org) in consecutively patch-tested patients, 2013/14, in 46 departments in 12 European countries. RESULTS: Altogether, 31 689 patients were included in the analysis. Compared to a similar analysis in 2004, the prevalence of contact allergy to methylisothiazolinone went up to around 20% in several departments. In comparison, contact allergy to the metals nickel, cobalt and chromium remained largely stable, at 18.1%, 5.9% and 3.2%, respectively, similar to mostly unchanged prevalence with fragrance mix I, II and Myroxylon pereirae (balsam of Peru) at 7.3%, 3.8% and 5.3%, respectively. In the subgroup of departments diagnosing (mainly) patients with occupational contact dermatitis, the prevalence of work-related contact allergies such as epoxy resin or rubber additives was found to be increased, compared to general dermatology departments. CONCLUSION: Continuous surveillance of contact allergy based on network data offers the identification of time trends or persisting problems, and thus enables focussing in-depth research (subgroup analyses, exposure analysis) on areas where it is needed.

Understanding the role of haptoglobin in psoriasis: effects of ultraviolet B.

BACKGROUND: Haptoglobin (Hp) is one of the acute phase proteins, whose main function is to bind free haemoglobin (Hb) and transport it to the liver for degradation and iron recycling. In addition to its role as an Hb scavenger, Hp has been shown to behave as an anti-inflammatory, antioxidant and angiogenic factor. We previously investigated the role of Hp in the pathogenesis of psoriasis, and found that it displays some structural modifications that might be associated with protein function in the disease. Phototherapy is an efficacious treatment for psoriasis, although the biological mechanisms by which phototherapy improves psoriasis are still unclear. AIM: To investigate the effects of ultraviolet (UV)B on Hp to clarify the role of Hp in psoriasis. METHODS: Expression of the genes encoding Hp, interleukin (IL)-6 and IL-10 was assessed in UVB-irradiated and unirradiated HaCaT cells. The biological significance of Hp modulation of UVB treatment was confirmed by ELISA and Western blotting. The Hp gene and protein expression in the skin of patients with psoriasis was also investigated. RESULTS: In vitro results showed that UVB modulated IL-6 and IL-10 gene expression and Hp gene and protein expression in HaCaT cells. The in vivo data also showed that Hp levels were increased in the skin of patients with psoriasis compared with healthy controls. CONCLUSIONS: UVB irradiation was able to modulate Hp production in immortalized keratinocytes. The higher levels of Hp in vivo in both lesional and nonlesional skin suggest that it might have a role in the pathogenesis of the disease.
