RESUMO
Detecting the association of genetic variants to the response of biological therapy represents an important advance in developing a personalized therapy. The aim of this work was to study the association of polymorphisms with an optimal response to tildrakizumab in patients with psoriasis in a real-life clinical practice. Ninety patients with plaque psoriasis recruited from-Spanish hospitals receiving tildrakizumab for at least 24 weeks were genotyped for 180 polymorphisms. Optimal response to tildrakizumab was evaluated by absolute PASI ≤1 at 6 and 12 months. Polymorphisms corrected for weight and disease duration with an FDR <0.15 were included in a multiple regression model. Sixty three percent of patients achieved an absolute PASI ≤1 at 6 months, while 71% did so after 12 months. Disease duration (>27 years) and weight (>76 kg) were associated with treatment response; after correcting by these factors, no association (FDR >0.15) was found for any polymorphism and response to tildrakizumab at 6 months. The analysis at 12 months identified the genotype GG for rs610604 (TNFAIP3), CT for rs9373839 (ATG5), and delCTGT/delCTGT for rs72167053 (PDE4D) as risk factors to not achieve an optimal response (PASI ≤1), while CT for rs708567 (IL17RC) was protective, independently of weight and disease duration (FDR <0.15). The final multivariable model at 12 months showed an AUC of 0.90 (95% CI 0.82 to -0.98). We identified a set of polymorphisms that could be helpful to identify psoriatic patients with an optimal response to tildrakizumab at 12 months in real-world practice conditions.

BACKGROUND: Prediction of the response to a biological treatment in psoriasis patients would allow efficient treatment allocation. OBJECTIVE: To identify polymorphisms associated with secukinumab response in psoriasis patients in a daily practice setting. METHODS: We studied 180 SNPs in patients with moderate-to-severe plaque psoriasis recruited from 15 Spanish hospitals. Treatment effectiveness was evaluated by absolute PASI ≤3 and ≤1 at 6 and 12 months. Individuals were genotyped using a custom Taqman array. Multiple logistic regression models were generated. Sensitivity, specificity and area under the curve (AUC) were analysed. RESULTS: A total of 173 patients were studied at 6 months, (67% achieved absolute PASI ≤ 3 and 65% PASI ≤ 1) and 162 at 12 months (75% achieved absolute PASI ≤ 3 and 64% PASI ≤ 1). Multivariable analysis showed the association of different sets of SNPs with the response to secukinumab. The model of absolute PASI≤3 at 6 months showed best values of sensitivity and specificity. Four SNPs were associated with the capability of achieving absolute PASI ≤ 3 at 6 months. rs1801274 (FCGR2A), rs2431697 (miR-146a) and rs10484554 (HLCw6) were identified as risk factors for failure to achieve absolute PASI≤3, while rs1051738 (PDE4A) was protective. AUC including these genotypes, weight of patients and history of biological therapy was 0.88 (95% CI 0.83-0.94), with a sensitivity of 48.6% and specificity of 95.7% to discriminate between both phenotypes. CONCLUSION: We have identified a series of polymorphisms associated with the response to secukinumab capable of predicting the potential response/non-response to this drug in patients with plaque psoriasis.

BACKGROUND: Atopic dermatitis (AD) is one of the most prevalent skin diseases, but there are numerous knowledge gaps surrounding the impact this disease has on quality of life (QoL), mental health, and out-of-pocket expenses involved in the management of AD. The available scientific evidence on the multidimensional burden of AD is usually based on studies with measures reported by patients themselves. METHODS: In this context, the MEASURE-AD trial was developed as a cross-sectional, multicenter, multinational trial using patient- and physician-reported measures to characterize the multidimensional burden of AD in adults with moderate-to-severe AD. RESULTS: This paper presents the results of the Spanish cohort. We found that Spanish adults with moderate-to-severe AD and high EASI score (21.1-72) had a significantly increased disease burden, high severity of symptoms such as itch and sleep disturbances, impaired mental health and QoL, higher use of health care resources, and more out-of-pocket expenses than patients with low EASI scores (0-7 or 7.1-21). CONCLUSIONS: This study provides information to better understand disease burden, and identify aspects to be improved in the management of AD.
RESUMO
INTRODUCTION: PRP is a rare entity of unknown etiopathogenesis. Lack of management guidelines makes it a challenge for clinicians. OBJECTIVE: To add our experience to increase evidence about PRP. METHODS: We performed a retrospective, descriptive and multicentric study of 65 patients with PRP, being the largest European case series of patients with PRP. RESULTS: PRP was more frequent in male patients with an average age of 51 years, but erythrodermic forms presented in older patients (average age 61 years). Six (75%) paediatric patients and ten (60%) non-erythrodermic adults controlled their disease with topical corticosteroids. On the contrary, 26 (68%) erythrodermic patients required biologic therapy as last and effective therapy line requiring an average of 6.5 months to achieve complete response. CONCLUSION: Our study showed a statistical difference in terms of outcome and response to treatment between children or patients with limited disease and patients who develop erythroderma.

BACKGROUND AND OBJECTIVE: A significant proportion of women of childbearing age have psoriasis. The aim of this study was to examine family planning concerns in this population. MATERIAL AND METHODS: Observational, descriptive, cross-sectional, multicenter study conducted between March 2020 and October 2021. We collected sociodemographic data and analyzed responses to a family planning questionnaire administered to women aged 18 to 45 years with plaque psoriasis who were candidates for systemic treatment. RESULTS: We studied 153 patients (mean [SD] age, 35.4 [8.0] years; mean disease duration, 16.7 years) being treated at 11 Spanish hospitals. Overall, 38.4% of women were considered to have moderate to severe psoriasis by their physicians; perceived severity ratings were significantly higher among women. Psoriasis affected the women's desire to become pregnant or led to their delaying pregnancy in 1 in 3 respondents. They were concerned that their condition might worsen if they had to discontinue or switch treatment or that the treatment might harm the baby. Approximately half of the women had not received family planning counseling from their physicians, and this was more likely to be the case among never-pregnant women. Women on biologic therapy (58.7%) had better psoriasis control and a better quality of life than women on other treatments. Their sexual health was also less affected. CONCLUSIONS: Women with psoriasis have numerous family planning concerns, which in some cases can lead them to delay pregnancy or affect their desire to become pregnant. Dermatologists need to receive better training regarding family planning in women with psoriasis so that they can provide their patients with more and better information.

INTRODUCTION: In 2017, the Spanish Academy of Dermatology and Venereology Psoriasis Working Group (PWG) designed the Minimal Disease Activity (MDA) criteria to determine the level of disease activity. We hereby present the results of an observational, cross-sectional, multicenter study of the nationwide application of these criteria. MATERIAL AND METHODS: We conducted a non-randomized sampling, stratified to achieve autonomic and provincial representation of consecutive patients with psoriasis (Ps) vulgaris without active arthritis. A total of 830 patients were included: 493 men (59.5%), with a mean age of 51.4 years (SD, 14.2), from all autonomous regions of Spain (except for Ceuta and Melilla) and 44 (88%) out of the 50 provinces. A questionnaire was obtained with demographic data, DLQI, subjective assessment-on a scale from 0 to 10-of itching, erythema, desquamation, visibility, and the patients' PASI and BSA. RESULTS: More than 50% failed to meet the MDA criteria (491; 59.2%), with significant differences being reported by region, sex, and age. Additionally, significant differences were reported based on the therapy used (P<.001). The use of biological therapies was associated with higher MDA compliance compared to other therapies (59.4% vs 23.3%). No differences were reported among various biological therapies. CONCLUSIONS: The overall rate of MDA compliance is low, with differences being based on geographic location, sex, age, and drug used, yet none of these factors separately justify them.
RESUMO
BACKGROUND: The past 5 years have seen a proliferation of new treatments for atopic dermatitis (AD). We analyzed recent drug survival data for cyclosporine in this setting. Because the Spanish National Healthcare system requires patients with AD to be treated with cyclosporine before they can be prescribed other systemic treatments, drug survival for cyclosporine may be shorter than in other diseases. MATERIAL AND METHOD: Multicenter, observational, prospective cohort study using data from the Spanish Atopic Dermatitis Registry (BIOBADATOP). Data from the Spanish Registry of Systemic Treatments in Psoriasis (BIOBADADERM) were used to create a comparison cohort. RESULTS: We analyzed data for 130 patients with AD treated with cyclosporine (median drug survival, 1 year). Median cyclosporine survival in the psoriasis comparison group (150 patients) was 0.37 years. Drug survival was significantly longer in AD than in psoriasis (P<.001). CONCLUSION: Drug survival of cyclosporine in the BIOBADATOP registry is similar to that described in other series of patients with AD and longer than that observed in the BIOBADADERM psoriasis registry.

BACKGROUND AND OBJECTIVE: Risankizumab - a humanized monoclonal antibody that targets the p19 subunit of IL-23 - has been recently approved to treat moderate-to-severe plaque psoriasis. Real-world data based on a representative pool of patients are currently lacking. OBJECTIVE: To assess the mid- and long-term safety and efficacy profile of risankizumab in patients with moderate-to-severe psoriasis in the routine clinical practice. METHODS: This was a retrospective and multicenter study of consecutive psoriatic patients on risankizumab from April 2020 through November 2022. The primary endpoint was the number of patients who achieved a 100% improvement in their Psoriasis Area and Severity Index (PASI) (PASI100) on week 52. RESULTS: A total of 510 patients, 198 (38.8%) women and 312 (61.2%) men were included in the study. The mean age was 51.7±14.4 years. A total of 227 (44.5%) study participants were obese (body mass index [BMI] >30kg/m2). The mean baseline PASI score was 11.4±7.2, and the rate of patients who achieved PASI100 on week 52, 67.0%. Throughout the study follow-up, 21%, 50.0%, 59.0%, and 66% of the patients achieved PASI100 on weeks 4, 16, 24, and 40, respectively. The number of patients who achieved a PASI ≤2 was greater in the group with a BMI ≤30kg/m2 on weeks 4 (P=.04), 16 (P=.001), and 52 (P=.002). A statistically significantly greater number of patients achieved PASI100 in the treatment-naïve group on weeks 16 and 52 (P=.001 each, respectively). On week 16 a significantly lower number of participants achieved PASI100 in the group with psoriatic arthropathy (P=.04). Among the overall study sample, 22 (4.3%) patients reported some type of adverse event and 20 (3.9%) discontinued treatment. CONCLUSIONS: Risankizumab proved to be a safe and effective therapy for patients with moderate-to-severe psoriasis in the routine clinical practice.
RESUMO
BACKGROUND: Several studies support the hypothesis that scabies is on the rise in Spain. There are also concerns about the possible development of resistance to treatment and an increase in atypical presentations. The aims of this study were to describe the demographic and clinical characteristics of patients with scabies seen by dermatologists in Spain, to identify the possible emergence of atypical forms of scabies, and to explore the frequency of treatment failures and associated risk factors. METHODS: We conducted an observational, cross-sectional, multicenter study of data collected prospectively in April and May 2023 using the CLINI-AEDVp platform created by the Spanish Academy of Dermatology and Venereology (AEDV). RESULTS: Participating dermatologists from 31 hospitals in 15 of Spain's autonomous communities recorded 186 cases of active scabies (51% in women) during the study period. A diagnostic certainty level of A, B or C as per the International Alliance for the Control of Scabies Consensus Criteria was required for diagnosis. Overall, 92% of patients had typical scabies and 66% had already been treated with a scabicide for the current episode. Of the treated patients, only 36% had received and completed adequate treatment (including the simultaneous treatment of all household members) and 50% had not received clear written recommendations. CONCLUSIONS: In a high proportion of the cases of scabies studied, the patient had already received treatment. In those cases, we observed several remediable shortcomings that could explain why some of these treatments had failed. Remedying these deficiencies should lead to better control of scabies and an improved assessment of the actual effectiveness of currently available scabicides.

BACKGROUND: Although the Spanish Ministry of Health prepares national therapeutic positioning reports (TPRs) and drug reimbursement policies, each of the country's 17 autonomous communities (ACs) is responsible for health care services and prescription requirements in its territory. The aim of the EQUIDAD study was to describe and explore potential differences in prescription requirements for new dermatology drugs across the autonomous communities. MATERIAL AND METHODS: Cross-sectional study conducted in April and May, 2023. Two dermatologists with management responsibilities from each autonomous community reported on territorial and more local prescription requirements for drugs covered by national TPRs issued between 2016 and 2022. RESULTS: Thirty-three researchers from 17 autonomous communities participated. The data submitted revealed between-community inequities in access to new drugs. Overall, 64.7% of the regions imposed additional prescription requirements to those mentioned in the TPRs for psoriasis. This percentage was lower for atopic dermatitis (35.3%) and melanoma (11.8%). The most common requirement for accessing a new drug was a previous prescription for another drug. Differences and additional requirements were also detected at the local level (i.e., differences between hospitals within the same autonomous community). CONCLUSIONS: Spain's autonomous communities have multiple regional and local prescription requirements that are not aligned with national TPR recommendations. These differences result in inequitable access to new drugs for both patients and practitioners across Spain.

Atopic dermatitis (AD) is a chronic or chronically recurrent Inflammatory dermatosis associated with multiple triggers that has a complex pathophysiological mechanism. It is characterized by a heterogeneous clinical expression, signs, and symptoms. Its etiology and pathogenesis are complex and are influenced by multiple immune-mediated factors. Treatment of AD can also be complex, given the high number of available drugs and multiple therapeutic targets. In this review, we summarize current literature on the efficacy and safety of topical and systemic drugs to treat moderate-to-severe AD. We begin with topical treatments such as corticosteroids and calcineurin inhibitors and subsequently address the latest systemic treatments, such as Janus kinase inhibitors (upadacitinib, baricitinib, abrocitinib, gusacitinib) and interleukin (IL) inhibitors, which have proven efficacious in AD, namely, dupilumab (IL-4 and IL-13), tralokinumab (IL-13), lebrikizumab (IL-13), and nemolizumab (IL-31). Given the large number of drugs available, we summarize the pivotal clinical trials for each drug, evaluate recent real-world experience in terms of safety and efficacy for purposes of compilation, and provide evidence to guide the optimal choice of therapy.

BACKGROUND AND OBJECTIVE: The data in clinical practice regarding the effectiveness and safety of brodalumab in psoriasis are scarce, especially at scalp and palmoplantar locations. The main objective was the percentage of patients achieving absolute PASI ≤3/ ≤1/ =0 for plaque psoriasis and the percentage of patients achieving an IGA 0-1/IGA 0 for the special locations at Week 52 of treatment. PATIENTS AND METHODS: Observational retrospective multicentre study in 28 Spanish Hospitals that included adult patients with plaque psoriasis treated with brodalumab, from September 2018 until March 2021. RESULTS: A total of 200 patients were included. The mean baseline PASI was 10.97 (±6.28) with a mean basal scalp (n = 58) and palmoplantar (n = 40) IGA of 2.10 (±0.97) and 2.15 (±1.26), respectively. At Week 52, 93.98%/75.90%/68.67% of patients reached an absolute PASI ≤3/ ≤1/ =0 in plaque psoriasis (n = 83), with a percentage of patients achieving scalp (n = 27) and palmoplantar (n = 19) IGA 0-1/IGA 0 of 96.3%/88.9% and 100%/88.9%, respectively. Fifteen per cent of patients reported any adverse events with candidiasis being the most reported (6%), but only 6% of the adverse events required the withdrawal. CONCLUSIONS: Brodalumab demonstrated high PASI and IGA responses and was well tolerated in clinical practice in plaque, scalp and palmoplantar psoriasis.

The advent of biosimilar drugs and their use in routine clinical practice has revolutionized the management of moderate to severe psoriasis and led to changes in the positioning of the existing molecules used to control this condition. Evidence from clinical trials complemented by real-world experience has helped to clarify concepts and has significantly changed the use and positioning of biologic agents in this setting. The present document is an update on the position of the Spanish Psoriasis Working Group regarding the use of biosimilar drugs, which takes into account this new situation.

BACKGROUND: Despite the large number of articles published on skin lesions related to COVID-19, clinicopathological correlation has not been performed consistently and immunohistochemistry to demonstrate spike 3 protein expression has not been validated through RT-PCR. MATERIAL AND METHODS: We compiled 69 cases of patients with confirmed COVID-19, where skin lesions were clinically and histopathologically studied. Immunohistochemistry (IHC) and RT-PCR was performed in skin biopsies. RESULTS: After a careful review of the cases, 15 were found to be dermatosis not related to COVID-19, while the rest of the lesions could be classified according to their clinical characteristics as vesicular (4), maculopapular eruptions (41), urticariform (9), livedo and necrosis (10) and pernio-like (5). Although histopathological features were similar to previously reported results, we found two previously unreported findings, maculopapular eruptions with squamous eccrine syringometaplasia and neutrophilic epitheliotropism. IHC showed in some cases endothelial and epidermal staining but RT-PCR was negative in all the tested cases. Thus, direct viral involvement could not be demonstrated. CONCLUSIONS: Despite presenting the largest series of confirmed COVID-19 patients with histopathologically studied skin manifestations, direct viral involvement was difficult to establish. Vasculopathic and urticariform lesions seem to be those more clearly related to the viral infection, despite IHC or RT-PCR negative results failed to demonstrate viral presence. These findings, as in other dermatological areas, highlight the need of a clinico-pathological correlation to increase knowledge about viral involvement in COVID-19 skin-related lesions.

Defining quality indicators is a key strategy for ensuring the quality and standardization of health care. The CUDERMA project, an initiative of the Spanish Academy of Dermatology and Venerology (AEDV), was undertaken to define quality indicators for the certification of specialized units in dermatology; the first 2 areas selected were psoriasis and dermato-oncology. The aim of this study was to reach a consensus on what should be assessed by the indicators used to certify psoriasis units. The structured process used to do this comprised a literature review to identify potential indicators, the selection of an initial set of indicators to be evaluated by a multidisciplinary group of experts and, finally, a Delphi consensus study. A panel of 39 dermatologists evaluated the selected indicators and classified them as either "essential" or "of excellence". Consensus was finally reached on 67 indicators, which will be standardized and used to develop the certification standard for psoriasis units.
