Real-World clinical, psychosocial and financial burden of atopic dermatitis: results from the Spanish cohort of the MEASURE-AD trial. / Carga clínica, psicosocial y económica de la dermatitis atópica en vida real: resultados de la cohorte española del estudio MEASURE-AD.

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.

Patient-reported outcome measures for assessing atopic dermatitis in clinical practice. / Medidas de resultados comunicados por el paciente para evaluar la dermatitis atópica.

Atopic dermatitis is a chronic skin condition that affects up to 20% of children and 10% of adults worldwide. Due to the high burden of dermatological signs and symptoms, atopic dermatitis has a significant impact on the quality of life of patients and their families. In the absence of objective measures to accurately assess severity and symptom burden, patient-reported outcome measures are essential to monitor the impact and progression of the disease, as well as the efficacy of treatments. Although there are currently no standardised guidelines for their use in clinical practice, there are some initiatives, such as the Harmonise Outcome Measures for Eczema and Vivir con Dermatitis Atópica, that can provide guidance. As healthcare systems move towards value-based healthcare models, patient-reported measures are becoming increasingly important for incorporating the patient perspective and improving the quality of healthcare services. The use of these measures can help monitor disease activity and guide treatment decisions. This article discusses the impact of atopic dermatitis and describes the patient-reported outcome measures commonly used in atopic dermatitis and the recommendations of the initiatives that have selected a core set of measures to best assess atopic dermatitis in clinical practice. Considering the recommendations of these initiatives and based on our experience in clinical practice, we propose the use of the Dermatology Life Quality Index to assess the impact of the disease on quality of life, the Patient-Oriented Eczema Measure to assess symptom severity, and the Numerical Rating Scale or the Visual Analogue Scale to measure itch intensity. To systematize the administration of these measures and to integrate them into hospital information systems and medical records, we emphasise the importance of telemedicine platforms that allow the electronic administration of these instruments.

Supervivencia de la ciclosporina en el tratamiento de la dermatitis atópica moderada-grave: Registro Español de Dermatitis Atópica (BIOBADATOP) / Drug Survival in Cyclosporine Treatment for Moderate to Severe Atopic Dermatitis: Analysis of the Spanish Atopic Dermatitis Registry (BIOBADATOP)

Antecedentes: Debido a la eclosión en el último quinquenio de nuevas alternativas terapéuticas para la dermatitis atópica (DA), nos planteamos estudiar la supervivencia actual de la ciclosporina (CsA) en esta patología. La CsA, como paso necesario solicitado por el Sistema Nacional de Salud de España para la autorización de otros tratamientos sistémicos, podría presentar una supervivencia menor que en otras enfermedades. Material y método: Estudio multicéntrico, observacional, de cohortes prospectivo para el que se recogieron pacientes incluidos en el Registro Español de Dermatitis Atópica (BIOBADATOP). Como cohorte de comparación se emplearon los datos del Registro Español de tratamientos sistémicos en Psoriasis (BIOBADADERM). Resultados: Se incluyeron 130 pacientes diagnosticados de DA que habían recibido CsA (mediana de supervivencia de CsA: 1 año). En el grupo comparador se incluyeron 150 pacientes psoriásicos que habían recibido CsA (mediana de supervivencia: 0,37 años). Observamos una mayor supervivencia de la CsA en los pacientes con DA en comparación con los pacientes psoriásicos (p<0,001). Conclusión: La supervivencia de la CsA en BIOBADATOP es similar a la descrita en otras series de pacientes con DA, y superior a la observada en los pacientes con psoriasis en el registro BIOBADADERM.(AU)

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.(AU)

Recommendations on the Use of Moisturizing Products Prepared by Spanish Dermatologists Using the Delphi Method. / Recomendaciones sobre el uso de productos hidratantes elaboradas por dermatólogos españoles mediante el método Delphi.

BACKGROUND AND OBJECTIVE: Moisturizing products are widely used in conditions affecting skin hydration. However, the lack of scientific evidence leads to discrepancies and great variability in the recommendations used by different health professionals. The aim of this consensus document is to generate recommendations based on the evidence and experience of dermatologists to unify and facilitate the use of moisturizing products in the routine clinical practice. MATERIALS AND METHODS: A 49-statement questionnaire on moisturizing products was prepared and, then, arranged in 5 blocks: 1) concept; 2) characteristics, 3) frequency and quantity, 4) product use and areas of application, and 5) special populations. Twenty-two expert dermatologists in the management of patients with eczema answered to the survey using a 2-round Delphi methodology (adding an item on the 2nd round). RESULTS: Consensus was reached on 27 statements (54%), most (n=23) via agreement. The highest level of agreement was reached in the blocks on quantity, product use and areas of application (77.8%), followed by the blocks on characteristics (73%) and frequency (62.5%). Regarding the blocks on concept and special populations, the level of consensus on the items proposed was 37.5% and 10%, respectively. Consensus on the use of emollients for xeroderma (71%) was higher vs atopic dermatitis (64%) and inflamed skin (33.3%). CONCLUSIONS: Consensus recommendations can help all prescribers and improve the available evidence regarding their use.

Condicionantes de acceso a nuevos medicamentos dermatológicos en España: resultados del proyecto EQUIDAD / Requirements for Accessing New Dermatology Drugs in Spain: Results of the EQUIDAD Study

Antecedentes: En España, aunque el Ministerio de Sanidad elabora el informe de posicionamiento terapéutico (IPT) y las condiciones de reembolso de los fármacos, las Comunidades Autónomas (CC. AA.) gestionan los servicios de salud y deciden sobre las condiciones de prescripción en su ámbito territorial. El objetivo del estudio EQUIDAD fue describir los condicionantes para la prescripción de los nuevos fármacos en Dermatología en las CC. AA. y sus posibles diferencias. Material y métodos: Estudio transversal realizado en abril-mayo del 2023. Dos dermatólogos con responsabilidades directivas de cada Comunidad Autónoma (C. A.) informaron sobre los condicionantes autonómicos y locales en la prescripción de los fármacos cuyo IPT para el tratamiento de enfermedades dermatológicas fue publicado en los años 2016-2022. Los datos fueron recogidos mediante un cuestionario online. Resultados: Un total de 33 investigadores de 17 CC. AA. participaron en el estudio. Se observaron inequidades entre CC. AA. para el acceso a los nuevos fármacos. Existieron condicionantes autonómicos adicionales al IPT en psoriasis en el 64,7% de las CC. AA., siendo este porcentaje menor en dermatitis atópica (35,3%) o melanoma (11,8%). El más frecuente fue el requisito de un orden de prescripción previo para el uso del fármaco. En algunas CC. AA. se detectaron además variaciones y condicionantes locales (diferencias entre centros de una misma C. A.). Conclusiones: Existe una multiplicidad de criterios tanto a nivel autonómico como local que añade restricciones adicionales a las establecidas por los IPT y que plantean una situación de inequidad entre los pacientes y los profesionales de las diferentes CC. AA. en el acceso a los nuevos fármacos. (AU)

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. (AU)

Efficacy and Safety of Dupilumab for the Treatment of Severe Atopic Dermatitis in Clinical Practice: A Single Center Experience / Eficacia y seguridad de dupilumab para el tratamiento de la dermatitis atópica grave en la práctica clínica: experiencia en un centro terciario

Background Dupilumab is a new targeted therapy for severe atopic dermatitis (AD) with limited real-world evidence. Objective Explore our experience with dupilumab for AD in clinical practice at a tertiary care center. Material and method Unicentric observational retrospective study including adult and pediatric patients with severe AD receiving dupilumab between December 2017 and December 2021. The Eczema Area and Severity Index (EASI) score, Pruritus Numerical Rating Scale (P-NRS) and Sleep disturbance Numerical Rating Scale (S-NRS) were recovered to assess severity and response. Results Fifty-nine patients received dupilumab: 52, 48, 26 and 13 patients reached 6, 12, 24 and 36 months of treatment, respectively. The EASI-75 response rates were 94.2%, 95.8%, 92.3% and 100% at months 6, 12, 24 and 36. The EASI-90 response rates were 63.5%, 72.9%, 84.6% and 92.3% at months 6, 12, 24 and 36. The EASI <7 response rates were 92.3%, 91.7%, 88.5% and 100% at months 6, 12, 24 and 36. The P-NRS ≥4 reduction rates were 86%, 87.5%, 92.3% and 100% at months 6, 12, 24 and 36. The S-NRS ≥4 reduction rates were 82.7%, 85.4%, 100% and 100% at months 6, 12, 24 and 36. Adverse events were mild and occurred in 20.3% of patients, all of them adults. Conclusion Our findings support dupilumab's favorable efficacy and tolerability profile in clinical practice. Dupilumab offers a rapid and sustained response, regardless of combined therapy. Longer follow-ups are still required to adequately assess its performance (AU)

Toward Precision Medicine in Atopic Dermatitis Using Molecular-Based Approaches / Hacia una medicina de precisión en la Dermatitis Atópica mediante el uso de enfoques moleculares

Atopic dermatitis is the most common chronic inflammatory skin disorder, affecting up to 20% of children and 10% of adults in developed countries. The pathophysiology of atopic dermatitis is complex and involves a strong genetic predisposition and T-cell driven inflammation. Although our understanding of the pathology and drivers of this disease has improved in recent years, there are still knowledge gaps in the immune pathways involved. Therefore, advances in new omics technologies in atopic dermatitis will play a key role in understanding the pathogenesis of this burden disease and could develop preventive strategies and personalized treatment strategies. In this review, we discuss the latest developments in genetics, transcriptomics, epigenomics, proteomics, and metagenomics and understand how integrating multiple omics datasets will identify potential biomarkers and uncover nets of associations between several molecular levels (AU)

La dermatitis atópica es el trastorno inflamatorio de la piel crónico más común. Afecta hasta a 20% de los niños y a 10% de los adultos en países desarrollados. La fisiopatología de la dermatitis atópica es compleja e implica una fuerte predisposición genética e inflamación impulsada por células T. Aunque nuestra comprensión de la patología y las causas de esta enfermedad ha mejorado en los últimos años, aún existen lagunas de conocimiento en las vías inmunológicas involucradas.

[Translated article] Requirements for Accessing New Dermatology Drugs in Spain: Results of the EQUIDAD Study.

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.

Drug Survival in Cyclosporine Treatment for Moderate to Severe Atopic Dermatitis: Analysis of the Spanish Atopic Dermatitis Registry (BIOBADATOP). / Supervivencia de la ciclosporina en el tratamiento de la dermatitis atópica moderada-grave: Registro Español de Dermatitis Atópica (BIOBADATOP).

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.

Requirements for Accessing New Dermatology Drugs in Spain: Results of the EQUIDAD Study. / Condicionantes de acceso a nuevos medicamentos dermatológicos en España: resultados del proyecto EQUIDAD.

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.

Efficacy and Safety of Dupilumab for the Treatment of Severe Atopic Dermatitis in Clinical Practice: A Single Center Experience. / [Artículo traducido]Eficacia y seguridad de dupilumab para el tratamiento de la dermatitis atópica grave en la práctica clínica: experiencia en un centro terciario.

BACKGROUND: Dupilumab is a new targeted therapy for severe atopic dermatitis (AD) with limited real-world evidence. OBJECTIVE: Explore our experience with dupilumab for AD in clinical practice at a tertiary care center. MATERIAL AND METHOD: Unicentric observational retrospective study including adult and pediatric patients with severe AD receiving dupilumab between December 2017 and December 2021. The Eczema Area and Severity Index (EASI) score, Pruritus Numerical Rating Scale (P-NRS) and Sleep disturbance Numerical Rating Scale (S-NRS) were recovered to assess severity and response. RESULTS: Fifty-nine patients received dupilumab: 52, 48, 26 and 13 patients reached 6, 12, 24 and 36 months of treatment, respectively. The EASI-75 response rates were 94.2%, 95.8%, 92.3% and 100% at months 6, 12, 24 and 36. The EASI-90 response rates were 63.5%, 72.9%, 84.6% and 92.3% at months 6, 12, 24 and 36. The EASI <7 response rates were 92.3%, 91.7%, 88.5% and 100% at months 6, 12, 24 and 36. The P-NRS ≥4 reduction rates were 86%, 87.5%, 92.3% and 100% at months 6, 12, 24 and 36. The S-NRS ≥4 reduction rates were 82.7%, 85.4%, 100% and 100% at months 6, 12, 24 and 36. Adverse events were mild and occurred in 20.3% of patients, all of them adults. CONCLUSION: Our findings support dupilumab's favorable efficacy and tolerability profile in clinical practice. Dupilumab offers a rapid and sustained response, regardless of combined therapy. Longer follow-ups are still required to adequately assess its performance.
