Equidad; Fármacos; Dermatitis atópicaEquity; Drugs; Atopic dermatitisEquitat; Medicaments; Dermatitis atòpicaAntecedentes 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.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

Erythroderma: A clinical study of 97 cases

BACKGROUND: Erythroderma is a rare skin disorder that may be caused by a variety of underlying dermatoses, infections, systemic diseases and drugs. METHODS: We reviewed the clinical, laboratory and biopsy material of 97 patients diagnosed with erythroderma who were treated in our department over a 6-year period (1996 through 2002). RESULTS: The male-female ratio was 1.85:1. The mean age at diagnosis was 46.2 years. The most common causative factors were dermatoses (59.7%), followed by drug reactions (21.6%), malignancies (11.3%) and idiopathic causes (7.2%). Carbamazepine was the most common drug (57.1%). The best clinicopathologic correlation was found in cutaneous T-cell lymphoma and pityriasis rubra pilaris related erythroderma. Apart from scaling and erythema that were present in all patients, pruritus was the most common finding (97.5%), followed by fever (33.6%), lymphadenopathy (21.3%), edema (14.4%) and hyperkeratosis (7.2%). CONCLUSION: This study outlines that underlying etiologic factors of erythroderma may show geographic variations. Our series had a high percentage of erythroderma secondary to preexisting dermatoses and a low percentage of idiopathic cases. There was no HIV-infected patient among our series based on multiple serum antibody tests. The clinical features of erythroderma were identical, irrespective of the etiology. The onset of the disease was usually insidious except in drug-induced erythroderma, where it was acute. The group associated with the best prognosis was that related to drugs

Clinical Practice Guideline on Melanoma From the Spanish Academy of Dermatology and Venereology (AEDV)

El diagnóstico y tratamiento del melanoma en atención especializada es un campo en el que se han producido numerosos cambios. El objetivo de esta guía es ofrecer a los dermatólogos españoles una referencia para resolver las dudas clínicas más frecuentes basándose en la evidencia actual. Para la realización de esta guía se escogió a miembros del Grupo Español de Dermato-Oncología y Cirugía con experiencia en el tratamiento de estos tumores y con interés en participar en la elaboración de la guía. Se hizo una adaptación de las guías de práctica clínica existentes mediante el método ADAPTE: inicialmente se resumió el proceso de atención y se elaboraron las preguntas clínicas relevantes. Se seleccionaron las guías mejor puntuadas mediante el instrumento AGREE II, realizando la búsqueda de las respuestas en dichas guías y elaborando las recomendaciones. Finalmente se sometió la guía a revisión externa. La guía se estructuró a partir de 21 preguntas clínicas que fueron seleccionadas por su relevancia, dado que se centran en aspectos que pueden plantear decisiones difíciles en el manejo del melanoma, y se han respondido empleando la evidencia obtenida de las mejores guías existentes. Entre las limitaciones de esta guía merece reseñarse que la evidencia es escasa para responder a algunas preguntas. En algunos aspectos el cambio es rápido y exige una actualización frecuente de la guía. Esta guía responde a preguntas habituales sobre el manejo del melanoma en la práctica clínica diaria, sirviendo a los dermatólogos como referencia en la toma de decisiones, siempre teniendo presente los recursos y preferencias del paciente

Mechanisms of local immunosuppression in cutaneous melanoma

Cutaneous melanoma is highly immunogenic, yet primary melanomas and metastases develop successfully in otherwise immunocompetent patients. To investigate the local immunosuppressive microenvironment, we examined the presence of suppressor T lymphocytes and tolerising dendritic cells (DCs), the expression of immunosuppressive cytokines (IL-10, TGFβ1 and TGFβ2) and the enzyme indoleamine 2,3-dioxygenase (IDO) using qRT–PCR and immunohistochemistry in primary skin melanomas, negative and positive sentinel lymph nodes (SLN), and lymph nodes with advanced metastases. Our results indicate that tolerogenic DCs and suppressor T lymphocytes are present in melanoma at all stages of disease progression. They express transforming growth factor β receptor 1 (TGFβR1), and are therefore susceptible to TGFβ1 and TGFβ2 specifically expressed by primary melanoma. We found that expression of IDO and interleukin 10 (IL-10) increased with melanoma progression, with the highest concentration in positive SLN. We suggest that negative SLN contain immunosuppressive cells and cytokines, due to preconditioning by tolerogenic DCs migrating from the primary melanoma site to the SLN. In primary melanoma, TGFβ2 is likely to render peripheral DCs tolerogenic, while in lymph nodes IDO and TGFβ1 may have a major effect. This mechanism of tumour-associated immunosuppression may inhibit the immune response to the tumour and may explain the discrepancy between the induction of systemic immunity by anti-melanoma vaccines and their poor performance in the clinic

Effects of tranexamic acid on death, disability, vascular occlusive events and other morbidities in patients with acute traumatic brain injury (CRASH-3): a randomised, placebo-controlled trial

Background Tranexamic acid reduces surgical bleeding and decreases mortality in patients with traumatic extracranial bleeding. Intracranial bleeding is common after traumatic brain injury (TBI) and can cause brain herniation and death. We aimed to assess the effects of tranexamic acid in patients with TBI. Methods This randomised, placebo-controlled trial was done in 175 hospitals in 29 countries. Adults with TBI who were within 3 h of injury, had a Glasgow Coma Scale (GCS) score of 12 or lower or any intracranial bleeding on CT scan, and no major extracranial bleeding were eligible. The time window for eligibility was originally 8 h but in 2016 the protocol was changed to limit recruitment to patients within 3 h of injury. This change was made blind to the trial data, in response to external evidence suggesting that delayed treatment is unlikely to be effective. We randomly assigned (1:1) patients to receive tranexamic acid (loading dose 1 g over 10 min then infusion of 1 g over 8 h) or matching placebo. Patients were assigned by selecting a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was head injury-related death in hospital within 28 days of injury in patients treated within 3 h of injury. We prespecified a sensitivity analysis that excluded patients with a GCS score of 3 and those with bilateral unreactive pupils at baseline. All analyses were done by intention to treat. This trial was registered with ISRCTN (ISRCTN15088122), ClinicalTrials.gov (NCT01402882), EudraCT (2011-003669-14), and the Pan African Clinical Trial Registry (PACTR20121000441277). Results Between July 20, 2012, and Jan 31, 2019, we randomly allocated 12 737 patients with TBI to receive tranexamic acid (6406 [50·3%] or placebo [6331 [49·7%], of whom 9202 (72·2%) patients were treated within 3 h of injury. Among patients treated within 3 h of injury, the risk of head injury-related death was 18·5% in the tranexamic acid group versus 19·8% in the placebo group (855 vs 892 events; risk ratio [RR] 0·94 [95% CI 0·86-1·02]). In the prespecified sensitivity analysis that excluded patients with a GCS score of 3 or bilateral unreactive pupils at baseline, the risk of head injury-related death was 12·5% in the tranexamic acid group versus 14·0% in the placebo group (485 vs 525 events; RR 0·89 [95% CI 0·80-1·00]). The risk of head injury-related death reduced with tranexamic acid in patients with mild-to-moderate head injury (RR 0·78 [95% CI 0·64-0·95]) but not in patients with severe head injury (0·99 [95% CI 0·91-1·07]; p value for heterogeneity 0·030). Early treatment was more effective than was later treatment in patients with mild and moderate head injury (p=0·005) but time to treatment had no obvious effect in patients with severe head injury (p=0·73). The risk of vascular occlusive events was similar in the tranexamic acid and placebo groups (RR 0·98 (0·74-1·28). The risk of seizures was also similar between groups (1·09 [95% CI 0·90-1·33]). Interpretation Our results show that tranexamic acid is safe in patients with TBI and that treatment within 3 h of injury reduces head injury-related death. Patients should be treated as soon as possible after injury.
