ABSTRACT

Introducción Los fármacos biológicos inhibidores del factor de necrosis tumoral (TNF) alfa son usados para tratar diferentes enfermedades inflamatorias. A pesar de su adecuado perfil de seguridad, se han descrito reacciones paradójicas asociadas a estos tratamientos. Material y método Se ha realizado una revisión retrospectiva de los pacientes en tratamiento con un anti-TNF que hubiesen presentado una reacción paradójica con afectación cutánea visitados en el Servicio de Dermatología del Hospital Universitari Parc Taulí de Sabadell. Resultados Registramos 30 pacientes en tratamiento con un anti-TNF que desarrollaron un efecto adverso cutáneo inmunomediado en forma de psoriasis (90%), alopecia (6,7%) o dermatitis neutrofílica (3,3%). Adalimumab fue el fármaco más implicado (56,7%), seguido de infliximab (40%). La morfología de la reacción psoriasiforme más descrita es la generalizada en placas (62,9%), seguida de la pustulosis palmo-plantar (37%). El 43,3% de los pacientes mantuvieron el anti-TNF, y de ellos el 92,3% obtuvieron una resolución total y parcial. De los 5 pacientes que iniciaron otro anti-TNF, ninguno obtuvo una resolución total. De los 8 pacientes que cambiaron a un tratamiento biológico diferente al anti-TNF, el 62,5% obtuvieron una resolución total o parcial. Discusión La aparición de una reacción paradójica no siempre obliga al cambio de tratamiento biológico, puesto que se ha observado la resolución de las lesiones cutáneas con un tratamiento tópico y/o sistémico adicional en más de la mitad de los pacientes, sin necesidad de suspender el anti-TNF. Si la afectación es grave, se debe plantear el cambio de tratamiento biológico, siendo más eficaz iniciar un fármaco dirigido a una diana terapéutica distinta al anti-TNF (AU)


Background Tumor necrosis factor α (TNF) inhibitors are used to treat different inflammatory diseases. Although these biologics have an adequate safety profile, they have been associated with paradoxical reactions. Material and methods Retrospective review of patients on TNF inhibitor therapy who developed a paradoxical skin reaction and were seen at the dermatology department of Hospital Universitari Parc Taulí in Sabadell, Spain. Results We collected data on 30 patients under treatment with a TNF inhibitor who developed an immune-mediated skin reaction in the form of psoriasis (90%), alopecia (6.7%), or neutrophilic dermatitis (3.3%). The most common drugs involved were adalimumab (56.7%) and infliximab (40%). Psoriasiform reactions mostly manifested as generalized plaques (62.9%) or palmoplantar pustulosis (37%). Thirteen patients (43.3%) continued on the same TNF inhibitor and 12 of them (92.3%) achieved partial or complete resolution of lesions. Five patients were switched to a different TNF inhibitor, but none of them achieved complete resolution. Eight patients were switched to a biologic with a different target, and 5 of them (62.5%) achieved partial or complete resolution. Conclusions Paradoxical reactions during TNF inhibitor therapy do not always require a change of treatment. In our series, the addition of a topical and/or systemic treatment resolved the skin lesions in more than half of the patients, and switching to a drug with a different target was more effective. A change of strategy should be contemplated in more serious cases (AU)

ABSTRACT

Introducción: La atención urgente en atención primaria es un ámbito clave del sistema sanitario, señalándose como un estresor importante el estar expuestos a recibir reclamaciones por responsabilidad profesional. El objetivo fue analizar las reclamaciones por responsabilidad profesional en la asistencia urgente de especialistas en medicina familiar y comunitaria y sus principales características en nuestro entorno.MétodosAnálisis descriptivo/retrospectivo de las reclamaciones contra especialistas de medicina familiar y comunitaria entre 1986 y 2015.ResultadosSe analizaron 224 reclamaciones, todas ellas resueltas, motivadas por error o retraso diagnóstico (122-54,5%), problemas de accesibilidad en la atención médica (48-21,4%), errores en el tratamiento (29-12,9%) y errores en la emisión de documentos (25-11,1%). En 147 (65,6%) se trataba de asistencia urgente y en 77 (34,3%) programada. La vía de interposición fue judicial en el 71,4%. En 6 casos (2,6%) la resolución implicó una indemnización, tratándose de 3 casos de asistencia urgente y 3 de programada.ConclusiónSe confirma el riesgo muy bajo de reclamación y de indemnización, no habiéndose hallado diferencias entre asistencia urgente y programada. Debe insistirse en aspectos de seguridad clínica, enfatizando en el error diagnóstico. (AU)


Introduction: Urgent assistance in primary care is a key area of the health system, being as an important stressor to be claimed for professional liability. The objective was to analyze the professional liability in primary care emergencies of specialists of family and community medicine and their main characteristics in our environment.MethodsRetrospective descriptive analysis of claims against General Practitioners between 1986 to 2015 was performed.Results224 claims, all resolved, were analyzed, due to error or diagnostic delay (122-54.5%), accessibility problems in medical care (48-21.4%), treatment errors (29-12.9%) and errors in the issuance of documents (25-11.1%). In 147 (65.6%) it was urgent assistance and in 77 (34.3%) scheduled. The way of interposition was judicial in 71.4%. In 6 cases (2.6%) the resolution involved compensation in 3 cases of urgent assistance and 3 of scheduled.ConclusionThe very low risk of claim and compensation payment is confirmed, with no differences found between urgent and scheduled assistance. Clinical safety aspects should be emphasized, especially in the diagnostic error. (AU)

ABSTRACT

BACKGROUND: Methotrexate (MTX) is frequently used in the treatment of moderate-to-severe psoriasis, however, there is limited data on health-related quality-of-life (HRQoL), psoriasis clinical outcomes and hepatic fibrosis in MTX-treated patients in routine clinical practice. OBJECTIVES: To investigate the impact of moderate-to-severe psoriasis in MTX-treated patients in Spain regarding to HRQoL, psoriasis clinical data and risk of hepatic fibrosis. METHODS: Observational, non-interventional, cross-sectional, retrospective, multicentre study, performed in Spain in moderate-to-severe plaque psoriasis patients treated with MTX > 16 weeks prior to inclusion. RESULTS: Despite ongoing treatment, 17.1% of 457 evaluable patients reported moderate-to-extreme impact on HRQoL (DLQI > 5); 21.4% BSA > 5 and 35.2% moderate-to-severe pruritus (VAS ≥ 4). Persistent severe psoriasis (PASI ≥ 10 and/or DLQI ≥ 10) was observed in 10.7%. Hepatic steatosis was identified in 64.1% of patients (HSI ≥ 36) and 37.2% of the patients were at-risk of advanced fibrosis which was associated to the MTX treatment duration. CONCLUSIONS: The study identified unmet needs in moderate-to-severe plaque psoriasis patients treated with MTX, revealing a significant proportion of sub-optimally controlled patients in terms of HRQoL and different domains of the disease. This study also found patients at-risk of advanced fibrosis, with evidence suggesting a correlation between longer exposures to MTX and higher risk of advanced fibrosis.

ABSTRACT

Objetivo: Establecer recomendaciones para conocer, identificar y manejar las necesidades psicológicas y emocionales de los pacientes con enfermedades inflamatorias crónicas dermatológicas en la práctica clínica habitual. Métodos: En una reunión de grupo nominal con expertos dermatólogos y psicólogos, se realizó una discusión guiada sobre las necesidades psicológicas y emocionales de estos pacientes, cómo abordarlas, y cuáles serían los criterios de derivación apropiados. A partir de todo ello, con la ayuda de un grupo focal de pacientes y de una revisión de la literatura, se preparó un documento matriz con las recomendaciones para su discusión, así como una encuesta tipo Delphi para evaluar el grado de acuerdo con las mismas, que se hizo extensiva a más dermatólogos y psicólogos. Resultados: Se establecieron 10 recomendaciones que podrían resumirse en las siguientes: explore la esfera psicológica de los pacientes con preguntas abiertas tanto en el momento del diagnóstico como durante el curso de la enfermedad. Dele explicaciones claras adaptadas a sus preocupaciones e infórmele de la existencia de asociaciones de pacientes. Explore si existen síntomas de ansiedad y depresión, y si se confirman mediantes una puntuación de 11 o más en la Hospital Anxiety and Depression Scale (HADS), valore una derivación a un especialista en salud mental. En las visitas, genere un clima de confianza, empatice con el paciente, consensúe con él los objetivos y opciones terapéuticas, y motívele para conseguir una buena adherencia. Conclusiones: Estas recomendaciones pueden servir a los profesionales sanitarios para que aborden de forma abierta y natural aspectos psicológicos y emocionales del paciente en la consulta diaria


Objective: To establish recommendations to determine, identify, and manage the psychological and emotional needs of patients with chronic inflammatory skin diseases in clinical practice. Methods: A guided discussion was held at meeting of a nominal group of expert dermatologists and psychologists on the psychological and emotional needs of patients with chronic inflammatory skin diseases, how to manage these cases, and which referral criteria to employ. Based on the results of the discussion, and with the aid of a patient focus group and a review of the literature, a master document was drawn up with recommendations for discussion. A Delphi survey was circulated among a larger group of dermatologists and psychologists to assess the level of agreement with the recommendations. Results: Ten recommendations were established and can be summarized as follows: explore the psychological sphere of the patients with open questions at the time of diagnosis and during the course of the disease; provide patients with clear explanations that address their concerns and inform them of the existence of patient associations; investigate symptoms of anxiety and depression and, if confirmed by means of a Hospital Anxiety and Depression score (HADS) of 11 or greater, consider referral to a mental-health specialist; and, during visits, create a climate of trust, empathize with patients, agree goals and treatment options with them, and motivate them to adhere to those treatments. Conclusions: These recommendations may help health care professionals address psychological and emotional aspects of their patients in daily clinical practice

ABSTRACT

BACKGROUND: Ixekizumab (anti-IL17A) is effective as treatment for moderate-to-severe plaque psoriasis, but real-life data on effectiveness and safety are currently very limited. OBJECTIVE: To evaluate the efficacy and safety of ixekizumab in a cohort of real-life plaque psoriasis patients. METHODS: Retrospective chart review of 100 patients with moderate-to-severe plaque psoriasis treated with ixekizumab at seven Spanish dermatological centres. RESULTS: According to the as observed analysis, the percentage of patients achieving a 75% and 90% of reduction from the baseline score of Psoriasis Area and Severity Index (PASI) was 87.5%-50.0% at week 12-16; 88.3%-58.4% at week 24 and 82.9%-58.5% at week 52, respectively. The mean ± standard deviation (SD) score of PASI at baseline was 12.9 ± 9.2, and it declined rapidly after ixekizumab administration to 1.9 ± 4.0 (P < 0.001) at week 12-16 and was maintained at 1.7 ± 4.1 and 1.8 ± 2.9 at week 24 and 52, respectively. Ixekizumab response was not affected by clinical variables like body mass index, disease duration or the presence of psoriatic arthritis. However, the bio-naive group showed significantly higher PASI 75 response rate at week 12-16 compared to patients previously exposed to biologic agents (P = 0.037). Twenty-six (26%) patients experienced adverse events (AEs) during the follow-up period, being most of them of mild-to-moderate intensity. The most common AE was local reaction at the site of injection (14/26; 53.8%). At the end of the observational period, 15 (15%) patients discontinued ixekizumab treatment due to limited clinical improvement (n = 11), adverse events (n = 3) or lost to follow-up (n = 1) within a mean ± SD time of 6.0 ± 3.9 months. CONCLUSION: The present study illustrates the initial experience with ixekizumab in real-world clinical practice confirming its usefulness and safety in the management of plaque psoriasis patients.

ABSTRACT

The demand for real-time monitoring of cell functions and cell conditions has dramatically increased with the emergence of organ-on-a-chip (OOC) systems. However, the incorporation of co-cultures and microfluidic channels in OOC systems increases their biological complexity and therefore makes the analysis and monitoring of analytical parameters inside the device more difficult. In this work, we present an approach to integrate multiple sensors in an extremely thin, porous and delicate membrane inside a liver-on-a-chip device. Specifically, three electrochemical dissolved oxygen (DO) sensors were inkjet-printed along the microfluidic channel allowing local online monitoring of oxygen concentrations. This approach demonstrates the existence of an oxygen gradient up to 17.5% for rat hepatocytes and 32.5% for human hepatocytes along the bottom channel. Such gradients are considered crucial for the appearance of zonation of the liver. Inkjet printing (IJP) was the selected technology as it allows drop on demand material deposition compatible with delicate substrates, as used in this study, which cannot withstand temperatures higher than 130 °C. For the deposition of uniform gold and silver conductive inks on the porous membrane, a primer layer using SU-8 dielectric material was used to seal the porosity of the membrane at defined areas, with the aim of building a uniform sensor device. As a proof-of-concept, experiments with cell cultures of primary human and rat hepatocytes were performed, and oxygen consumption rate was stimulated with carbonyl-cyanide-4-(trifluoromethoxy)phenylhydrazone (FCCP), accelerating the basal respiration of 0.23 ± 0.07 nmol s-1/106 cells up to 5.95 ± 0.67 nmol s-1/106 cells s for rat cells and the basal respiration of 0.17 ± 0.10 nmol s-1/106 cells by up to 10.62 ± 1.15 nmol s-1/106 cells for human cells, with higher oxygen consumption of the cells seeded at the outflow zone. These results demonstrate that the approach of printing sensors inside an OOC has tremendous potential because IJP is a feasible technique for the integration of different sensors for evaluating metabolic activity of cells, and overcomes one of the major challenges still remaining on how to tap the full potential of OOC systems.

ABSTRACT

ANTECEDENTES: En situaciones clínicas difíciles de psoriasis moderada y grave la información sobre las estrategias terapéuticas más adecuadas es insuficiente. MATERIAL Y MÉTODOS: Se plantearon 5 escenarios: psoriasis pediátrica, infecciones en pacientes tratados con biológicos, localizaciones difíciles, supervivencia de las terapias biológicas e impacto en la calidad de vida, identificando aquellas cuestiones en las que la evidencia era controvertida o insuficiente. Tras la discusión con un grupo de dermatólogos expertos en el manejo de la psoriasis moderada-grave, se llevó a cabo un cuestionario que fue implementado según la metodología Delphi. RESULTADOS: Se alcanzó el consenso en 66 de los 93 ítems finales planteados (70,9%) (49 en el acuerdo, 17 en el desacuerdo). Se acordó la conveniencia de incorporar la evaluación del índice de masa corporal, las comorbilidades metabólicas y la medición de la calidad de vida en el seguimiento de la psoriasis infantil. En este grupo de edad, el metotrexato y el etanercept se consideraron las mejores opciones de tratamiento sistémico y biológico, respectivamente. Aunque la evidencia científica se interpretó como heterogénea y de difícil extrapolación, se consensuó que la individualización y la flexibilidad en las dosis, el tratamiento continuo y las combinaciones terapéuticas incrementaban la supervivencia del fármaco. Se acordó la conveniencia de incorporar el índice de calidad de vida en dermatología como marcador de eficacia terapéutica y en la toma de decisiones en la práctica clínica. CONCLUSIONES: La opinión estructurada de los expertos contribuye en la toma de decisiones en aquellos aspectos en los que la información disponible es incompleta o contradictoria


BACKGROUND: There is insufficient information on how best to treat moderate to severe psoriasis in difficult clinical circumstances. MATERIAL AND METHODS: We considered 5 areas where there is conflicting or insufficient evidence: pediatric psoriasis, risk of infection in patients being treated with biologics, psoriasis in difficult locations, biologic drug survival, and impact of disease on quality of life. Following discussion of the issues by an expert panel of dermatologists specialized in the management of psoriasis, participants answered a questionnaire survey according to the Delphi method. RESULTS: Consensus was reached on 66 (70.9%) of the 93 items analyzed; the experts agreed with 49 statements and disagreed with 17. It was agreed that body mass index, metabolic comorbidities, and quality of life should be monitored in children with psoriasis. The experts also agreed that the most appropriate systemic treatment for this age group was methotrexate, while the most appropriate biologic treatment was etanercept. Although it was recognized that the available evidence was inconsistent and difficult to extrapolate, the panel agreed that biologic drug survival could be increased by flexible, individualized dosing regimens, continuous treatment, and combination therapies. Finally, consensus was reached on using the Dermatology Quality of Life Index to assess treatment effectiveness and aid decision-making in clinical practice. CONCLUSIONS: The structured opinion of experts guides decision-making regarding aspects of clinical practice for which there is incomplete or conflicting information

ABSTRACT

INTRODUCCIÓN: Las asociaciones de pacientes son un elemento más del sistema sanitario, sin embargo en España se desconoce la funcionalidad y el respaldo que tienen según sus propios asociados. OBJETIVO: Estudiar la funcionalidad de la principal asociación española de pacientes y familiares afectados por la psoriasis según sus propios socios. MATERIAL Y MÉTODOS: Estudio mediante un cuestionario autoadministrado a una muestra de socios y/o simpatizantes (población total = 26.349 personas). Se estudió la credibilidad, confianza y satisfacción y se comparó con otros agentes sanitarios. El cuestionario de funcionalidad se analizó con un modelo de Rasch, y se examinó si había diferencias entre grupos de participantes con la prueba de ANOVA. RESULTADOS: Participaron 746 socios y/o simpatizantes (tasa de respuesta 2,83%). La credibilidad de la asociación se situó tras la de los especialistas que tratan la psoriasis. El respaldo medio a la función de la asociación fue notable (7,53 en una escala de 0 a 10). Según los socios las funciones mejor puntuadas se relacionaban con acciones colectivas para sensibilizar a la sociedad sobre el problema de la psoriasis, en cambio, tuvieron una menor valoración las acciones relacionadas con los servicios de atención personalizada. Solo hubo diferencias significativas (p < 0,05) en el respaldo a la asociación en función del nivel académico de los participantes. CONCLUSIONES: Las asociaciones son unas instituciones que contribuyen a la difusión de información de la enfermedad, que cuidan y representan a los pacientes. Los profesionales de salud e instituciones deberían tenerlas en cuenta para afrontar la psoriasis y diseñar políticas de salud efectivas


INTRODUCTION: Patient associations form part of health care systems, but little is known about how their members' view the functionality of these associations and whether they endorse their goals and activities. OBJECTIVE: To study how the members of the leading Spanish association of patients with psoriasis and their relatives view the group's functioning. MATERIAL AND METHODS: Survey study using a self-administered questionnaire answered by members of the association (total membership, 26 349 persons). The credibility of the association and respondents' confidence in and satisfaction with it were studied and compared with their attitudes toward other agents in the health care system. A Rasch model was used to analyze respondents' ranking of functions. Analysis of variance was used to study between-group differences. RESULTS: A total of 746 members participated (response rate 2.83%). The association's credibility was rated in second place, after that of specialists who treat psoriasis. Support for the association functions was good (7.53 on a scale of 0 to 10). The function the members rated highest was the raising of societal awareness of psoriasis and its problems. Rated lowest were functions related to personal services for members. Educational level was the only participant factor associated with significant differences in evaluations (P < .05). CONCLUSIONS: The psoriasis association contributes by disseminating information about the disease and patient care, and it serves to represent patients.

ABSTRACT

INTRODUCTION: Patient associations form part of health care systems, but little is known about how their members' view the functionality of these associations and whether they endorse their goals and activities. OBJECTIVE: To study how the members of the leading Spanish association of patients with psoriasis and their relatives view the group's functioning. MATERIAL AND METHODS: Survey study using a self-administered questionnaire answered by members of the association (total membership, 26 349 persons). The credibility of the association and respondents' confidence in and satisfaction with it were studied and compared with their attitudes toward other agents in the health care system. A Rasch model was used to analyze respondents' ranking of functions. Analysis of variance was used to study between-group differences. RESULTS: A total of 746 members participated (response rate 2.83%). The association's credibility was rated in second place, after that of specialists who treat psoriasis. Support for the association functions was good (7.53 on a scale of 0 to 10). The function the members rated highest was the raising of societal awareness of psoriasis and its problems. Rated lowest were functions related to personal services for members. Educational level was the only participant factor associated with significant differences in evaluations (P<.05). CONCLUSIONS: The psoriasis association contributes by disseminating information about the disease and patient care, and it serves to represent patients. Health professionals and institutions should take the association into account in their efforts to deal with the disease and in designing effective policies.

ABSTRACT

BACKGROUND: There is insufficient information on how best to treat moderate to severe psoriasis in difficult clinical circumstances. MATERIAL AND METHODS: We considered 5 areas where there is conflicting or insufficient evidence: pediatric psoriasis, risk of infection in patients being treated with biologics, psoriasis in difficult locations, biologic drug survival, and impact of disease on quality of life. Following discussion of the issues by an expert panel of dermatologists specialized in the management of psoriasis, participants answered a questionnaire survey according to the Delphi method. RESULTS: Consensus was reached on 66 (70.9%) of the 93 items analyzed; the experts agreed with 49 statements and disagreed with 17. It was agreed that body mass index, metabolic comorbidities, and quality of life should be monitored in children with psoriasis. The experts also agreed that the most appropriate systemic treatment for this age group was methotrexate, while the most appropriate biologic treatment was etanercept. Although it was recognized that the available evidence was inconsistent and difficult to extrapolate, the panel agreed that biologic drug survival could be increased by flexible, individualized dosing regimens, continuous treatment, and combination therapies. Finally, consensus was reached on using the Dermatology Quality of Life Index to assess treatment effectiveness and aid decision-making in clinical practice. CONCLUSIONS: The structured opinion of experts guides decision-making regarding aspects of clinical practice for which there is incomplete or conflicting information.

ABSTRACT

Metotrexato (MTX) es el fármaco sistémico convencional más empleado en el tratamiento de la psoriasis. A pesar de que la experiencia en su uso se remonta a más de 50 años, todavía existen aspectos en el manejo clínico poco estandarizados o conocidos. Bajo esta premisa, un grupo de 15 expertos participó en una conferencia de consenso en la que, a partir de una revisión sistemática y 2 rondas de validación previas, se validaron recomendaciones categorizadas por nivel de evidencia y grado de recomendación sobre el uso de MTX en la psoriasis. La elección de MTX en el tratamiento de la psoriasis moderada grave requiere la evaluación previa de la idoneidad del fármaco, incluyendo estado de vacunación, cribado de tuberculosis y gestación. La dosis recomendada de inicio es de 10-20mg/semana si el paciente no presenta factores de riesgo, con una dosis terapéutica de 15mg/semana para la mayoría de pacientes y máxima de 20mg/semana. La mayor parte de pacientes que respondan al tratamiento mostrarán mejoría antes de las 8 semanas. Es preferible la administración parenteral de MTX cuando exista riesgo de error en la pauta de administración, incumplimiento, intolerancia gastrointestinal o respuesta insuficiente a dosis plenas por vía oral. Los métodos no invasivos son preferibles para la monitorización de la hepatotoxicidad. El tratamiento con MTX representa una buena opción en pacientes con antecedentes oncológicos, mientras que no se recomienda en pacientes portadores crónicos de virus de la hepatitisB o seropositivos para el virus de la inmunodeficiencia humana (VIH+)


Methotrexate (MTX) is the most frequently used conventional systemic drug in the treatment of psoriasis. Despite over 50 years of experience in this setting, certain aspects of the use of this drug in clinical practice are still little standardized and poorly understood. For this reason, a group of 15 experts took part in a consensus development conference to achieve consensus on a series of recommendations on the use of MTX in psoriasis. The guidelines, which were developed on the basis of a systematic review of the literature, were validated by 2 rounds of voting and categorized by level of evidence and grade of recommendation. Before MTX can be used to treat moderate to severe psoriasis, the patient must be evaluated to assess the suitability of the treatment, including consideration of vaccination status and screening for tuberculosis and pregnancy. The recommended starting dose for a patient with no risk factors is 10 to 20mg/wk, the therapeutic dose for most patients is 15mg/wk, and the maximum dose is 20mg/wk. Most patients who respond to treatment will show improvement within 8weeks. Parenteral administration of MTX is desirable when there is a risk of erroroneous dosing, nonadherence, gastrointestinal intolerance, or inadequate response to the therapeutic dose taken orally. Noninvasive methods are preferred for monitoring hepatotoxicity. MTX is a good treatment option for patients with a history of cancer, but is not recommended in patients with chronic hepatitisB infection or individuals who are seropositive for human immunodeficiency virus
