Consensus of Spanish Society of Hospital Pharmacy on optimal medication therapy management of atopic dermatitis / Consenso de la Sociedad Española de Farmacia Hospitalaria en manejo fármacoterapéutico óptimo de la dermatitis atópica

Aim: This study's aims are: 1) To use the Delphi method to determine the level of consensus among hospital pharmacists (HPs) as regards the factors involved in the current approach to patients with atopic dermatitis (AD); 2) To identify potential areas for improvement in hospital pharmacy in terms of dealing with patients with severe AD; and 3) To contribute to adequate pharmaceutical care for patients with AD by drawing up recommendations. Methods: A two-round Delphi survey with participation from HPs from all over Spain. Three theme-based blocks were set out: 1) AD; 2) Management of patients with severe AD in the Hospital Pharmacy setting; and 3) Unmet needs (pathology, patient, treatment and management). Results: The 42 HPs participating reached a consensus in recognising the impact of severe AD on the patients suffering from it, the need to encourage adherence and the recommendations to use scales that take into account the patient's quality of life and indicators of the patient's experience. It has also been demonstrated that it is worthwhile evaluating the results in real clinical practice in consensus with other specialists from the multidisciplinary team. Finally, it is advisable to use drugs that have demonstrated long-term effectiveness and safety for patients with severe AD, given the disease's chronic nature. Conclusions: This Delphi consensus highlights the impact of severe AD on patients, the importance of a multidisciplinary and holistic approach, in which HP play a major role. It also highlights the importance of increased access to new drugs to improve health outcomes. (AU)

Objetivos: Los objetivos de este estudio son: 1) Determinar, mediante el método Delphi, el grado de consenso existente entre los farmacéuticos de hospital (FH) en cuanto a los factores que intervienen en el abordaje actual de los pacientes con dermatitis atópica (DA); 2) Identificar posibles áreas de mejora en la farmacia hospitalaria en cuanto al abordaje de los pacientes con DA grave; y 3) Contribuir a una adecuada atención farmacéutica a los pacientes con DA mediante la elaboración de recomendaciones. Método: Una encuesta Delphi con participación de FHs de toda España. Se establecieron tres bloques temáticos: 1) DA; 2) Manejo de pacientes con DA grave desde Farmacia Hospitalaria; y 3) Necesidades no cubiertas (patología, paciente, tratamiento y manejo). Resultados: Los 42 FHs participantes llegaron a un consenso en el reconocimiento del impacto de la DA grave en los pacientes, la necesidad de fomentar la adherencia y las recomendaciones de utilizar escalas que tengan en cuenta la calidad de vida del paciente e indicadores de la experiencia. También se muestra la conveniencia de evaluar los resultados en la práctica clínica real en consenso con otros especialistas del equipo multidisciplinar. Por último, es aconsejable utilizar fármacos que hayan demostrado eficacia y seguridad a largo plazo para los pacientes con DA grave, dado el carácter crónico de la enfermedad. Conclusiones: Este consenso Delphi pone de manifiesto el impacto de la DA grave en los pacientes, la importancia del abordaje multidisciplinar y holístico, en el que el FH juega un papel de gran importancia. También se resalta la importancia de un mayor acceso a nuevos fármacos que permitan mejorar resultados en salud. (AU)

[Translated article] Biological and immunosuppressive medications in pregnancy, breastfeeding and fertility in immune mediated diseases.

OBJECTIVE: The objective of this review is to gather the available evidence on the different drugs used in immune-mediated inflammatory diseases in pregnancy, lactation, their influence on female and male fertility, advice on discontinuation before conception and to help in routine clinical practice for better patient advice on family planning. METHODS: A bibliographic search was carried out, where published articles (review studies, observational studies and case series) in English or Spanish until April 2020 that analyzed the management of pregnancy, lactation and/or fertility in patients on treatment in immune-mediated diseases were selected. RESULTS: A total of 95 references were selected and the information on each drug was synthesized in tables. Drugs contraindicated in pregnancy are topical retinoids, pimecrolimus, cyclooxygenase 2 inhibitors, methotrexate, mycophenolate mofetil, leflunomide, acitretin, and thiopurines. The lack of data advises against the use of apremilast, tofacitinib, baricitinib, anakinra, abatacept, tocilizumab and the new biologicals. Topical salicylates, paracetamol, ultraviolet therapy and hydroxychloroquine treatment are safe, and anti-TNF biological therapy are considered low risk, with certolizumab being the drug of choice throughout pregnancy and lactation. Most are compatible with paternal exposure except for sulfasalazine, mycophenolate and leflunomide, for which suspension of treatment prior to conception is recommended, and cyclosporine with dose requirements of less than 2 mg/kg/day. CONCLUSIONS: In this context of chronic treatments with teratogenic potential, it is necessary to highlight the importance of pregnancy planning to select the safest drug. Given the quality of the available data, it is still necessary to continuously update the information, as well as to promote observational studies of cohorts of pregnant patients and men of childbearing age, including prospective studies, in order to generate more scientific evidence.

Medicamentos inmunosupresores y biológicos en el embarazo, la lactancia y la fertilidad en enfermedades inmunomediadas / Biological and immunosuppressive medications in pregnancy, breastfeeding and fertility in immune mediated diseases

Objetivo: El objetivo de esta revisión es reunir la evidencia disponible de los diferentes medicamentos utilizados en las enfermedades inflamatorias inmunomediadas en la gestación y lactancia, su influencia en la fertilidad femenina y masculina, consejos sobre su suspensión antes de la concepción y servir de ayuda en la práctica clínica habitual para un mejor consejo al paciente en la planificación familiar.Métodose realizó una búsqueda bibliográfica, donde se seleccionaron los artículos publicados (estudios de revisión, observacionales y series de casos) en lengua inglesa o española hasta abril de 2020 que analizaban el manejo del embarazo, la lactancia y/o la fertilidad en pacientes con tratamientos utilizados en las enfermedades inflamatorias inmunomediadas de dermatología, reumatología y digestivas.Resultadosse seleccionaron un total de 95 referencias y se sintetizó la información de cada medicamento en tablas. Los fármacos contraindicados en el embarazo son los retinoides tópicos, pimecrolimus, inhibidores de la ciclooxigenasa 2, metotrexato, micofenolato de mofetilo, leflunomida, acitretina y tiopurinas. La falta de datos desaconseja el uso de apremilast, tofacitinib, baricitinib, anakinra, abatacept, tocilizumab y los nuevos biológicos. Mientras que son seguros los salicilatos y los emolientes tópicos, el paracetamol, la terapia ultravioleta, la hidroxicloroquina y en la terapia biológica los anti-TNF se consideran de bajo riesgo, siendo el certolizumab el de elección durante todo el embarazo y la lactancia. La mayoría son compatibles con la exposición paterna, excepto algunos como la sulfasalazina, micofenolato y leflunomida, que se recomienda la suspensión del tratamiento previa a la concepción, y la ciclosporina con requerimientos de dosis inferiores a 2 mg/kg/día.

Incidence of COVID-19 in patients under chronic treatment with hydroxychloroquine.

OBJECTIVE: To analyze the incidence of Covid-19 in patients who are chronic users of hydroxychloroquine. PATIENTS AND METHODS: Cross-sectional retrospective observational multicenter study in health areas and districts from Castilla La-Mancha and Andalucia. Of the 4451 participants included in the first recruitment, 3817 with valid data were selected. The main variable of the study is the presence or absence of Covid-19 infection by clinical, serological or polymerase chain reaction diagnosis. Sociodemographic and clinical variables and treatment and concomitant comorbidities were recorded. RESULTS: 169 (4,45%) patients had Covid-19 infection, of which 12 (7.1 %) died and 32 (18.9%) required hospital admission. Previous respiratory pathology was related to Covid-19 infection (P < .05). Maculopathy appears in 5.3% of patients and is significantly related to the dose of hydroxychloroquine consumed (P < .05). CONCLUSION: There is no relationship between chronic use of hydroxychloroquine and the incidence of Covid-19.

OBJETIVO: Analizar la incidencia de la enfermedad del coronavirus 19 (COVID-19) en pacientes consumidores crónicos de hidroxicloroquina. PACIENTES Y MÉTODOS: Estudio multicéntrico observacional retrospectivo transversal en Áreas de Salud de Castilla La-Mancha y distritos sanitarios de Andalucía. De los 4.451 participantes incluidos en el primer reclutamiento se seleccionaron 3.817 sujetos con datos válidos. La variable principal del estudio ha sido la presencia o ausencia de infección por la COVID-19 por diagnóstico clínico, serológico o por reacción en cadena de la polimerasa. Se registraron variables sociodemográficas, clínicas y tratamientos y comorbilidades concomitantes. RESULTADOS: Ciento sesenta y nueve (4,45%) pacientes presentaron infección por la COVID-19, de los cuales fallecieron 12 (7,1%) y 32 (18,9%) requirieron ingreso hospitalario. La enfermedad respiratoria previa se relacionó con la infección por la COVID-19 (p < 0,05). La maculopatía aparece en un 5,3% de los pacientes y está relacionada significativamente con la dosis de hidroxicloroquina consumida (p < 0,05). CONCLUSIÓN: No existe relación entre consumo crónico de hidroxicloroquina e incidencia de la COVID-19.

Standardization and Chemical Characterization of Intravenous Therapy in Adult Patients: A Step Further in Medication Safety.

BACKGROUND: Intravenous drug administration is associated with potential complications, such as phlebitis. The physiochemical characteristics of the infusate play a very important role in some of these problems. AIM: The aim of this study was to standardize the dilutions of intravenous drugs most commonly used in hospitalized adult patients and to characterize their pH, osmolarity and cytotoxic nature to better guide the selection of the most appropriate vascular access. METHODS: The project was conducted in three phases: (i) standardization of intravenous therapy, which was conducted using a modified double-round Delphi method; (ii) characterization of the dilutions agreed on in the previous phase by means of determining the osmolarity and pH of each of the agreed concentrations, and recording the vesicant nature based on the information in literature; and (iii) algorithm proposal for selecting the most appropriate vascular access, taking into account the information gathered in the previous phases. RESULTS: In total, 112 drugs were standardized and 307 different admixtures were assessed for pH, osmolarity and vesicant nature. Of these, 123 admixtures (40%), had osmolarity values >600 mOsm/L, pH < 4 or > 9, or were classified as vesicants. In these cases, selection of the most suitable route of infusion and vascular access device is crucial to minimize the risk of phlebitis-type complications. CONCLUSIONS: Increasing safety of intravenous therapy should be a priority in the healthcare settings. Knowing the characteristics of drugs to assess the risk involved in their administration related to their physicochemical nature may be useful to guide decision making regarding the most appropriate vascular access and devices.

Targeted Therapies for Eosinophilic Gastrointestinal Disorders.

The growing recognition of eosinophilic gastrointestinal disorders has revealed the limitations of current treatment (mainly based on dietary modification and corticosteroids), and include refractoriness, high recurrence rates, and the need for long-term therapy. Research efforts, mainly in eosinophilic esophagitis (EoE), have unveiled essential pathophysiological mechanisms leading to these disorders, which bear some similarities to those of atopic manifestations and are shared by eosinophilic gastroenteritis (EGE) and eosinophilic colitis (EC). Novel targeted therapies, some imported from bronchial asthma and atopic dermatitis, are currently being assessed in EoE. The most promising are monoclonal antibodies, including those targeting interleukin (IL)-13 (cendakimab) and IL-4 (dupilumab), with phase 3 trials currently ongoing. The potential of anti-integrin therapy (vedolizumab) and Siglec-8 blockers (antolimab) in EGE are also promising. Non-biological therapies for eosinophilic gut disorders, which include preventing the activation of Janus kinase (JAK)-signal transducer and activator of transcription (STAT) and chemoattractant receptor expressed on T helper 2 cells (CRTH2) signaling pathways, and other potential targets that deserve investigation in eosinophilic gut disorders, are reviewed.

Objetivo: Describir los dispositivos para la obtención de Plasma Rico en Plaquetas (PRP) mediante la revisión de los productos existentes en España, teniendo en consideración las aportaciones de la Agencia Española de Medicamentos y Productos Sanitarios (AEMPS) y los grupos de trabajo de Productos Sanitarios (GPS), Farmacotecnia y Hemoderivados de la Sociedad Española de Farmacia Hospitalaria (SEFH). Método: Se realizaron tres búsquedas independientes sobre dispositivos de fraccionamiento de plasma. Se contactó con los proveedores y se estableció una reunión con cada uno de ellos. Se revisaron las características de cada dispositivo mediante una demostración del proceso de fraccionamiento virtual y se elaboró una tabla de comparación de kits. Los dispositivos se clasificaron como Técnica cerrada y Técnica abierta de acuerdo al informe del comité técnico de inspección de la AEMPS. Resultados: Se localizaron diez dispositivos: ACP®; Angel®, Cascade®, Endoret®, GPS®, Magellan®, Minos®, Ortho-pras®, Smart-prepr® y Tricell®, pudiendo conocer de forma detallada el funcionamiento en siete de ellos. Sin embargo, de Cascade®, Magellan® y Smart-prepr® no se consiguió información suficiente. Conclusión: La revisión permitió conocer los principales dispositivos de extracción de PRP disponibles con marcado CE y sus características diferenciales; sin embargo, para garantizar la cali dad del producto final es crucial poner atención en el propio proceso de extracción y administración del PRP. El Servicio de Farmacia debe implicarse en su selección por la estrecha relación que mantiene con la calidad del medicamento elaborado. El trabajo conjunto con la AEMPS permitirá definir de forma más específica el proceso correcto de elaboración (AU)

Técnicas de obtención del plasma rico en plaquetas y su empleo en terapéutica osteoinductora / Methods to obtain platelet-rich plasma and osteoinductive therapeutic use

Introducción: El Plasma Rico en Plaquetas (PRP) es un plasma autólogo con una cifra de plaquetas superior a la del plasma basal, por haber sido sometido a algún proceso de extracción y concentración. El empleo del PRP como osteoinductor es conflictivo dado que, no existen estudios clínicos rigurosos que permita extraer conclusiones firmes respecto a su utilidad. Objetivo: Proporcionar información sobre las técnicas de obtención del PRP, las consideraciones legales sobre su obtención y empleo, el mecanismo de acción molecular, así como la evidencia disponible sobre su seguridad y tolerancia. Resultado: El PRP se obtiene de forma manual, mediante 'técnica abierta', o mediante kits desechables con 'técnica cerrada', siendo estos últimos productos sanitarios clasificados como IIa. La Agencia Española de Medicamentos y Productos Sanitarios (AEMPS) considera el PRP como medicamento, estableciendo unos requisitos mínimos para garantizar su seguridad, trazabilidad, farmacovigiliancia e información. El PRP, por su elevado contenido en factores de crecimiento, reúne cualidades para ser un potente papel osteoinductor, capaz de acelerar la consolidación de fracturas o de osteointegrar rápida y eficientemente distintos tipos de implantes óseos. La tolerancia a la infiltración es generalmente buena, aunque hay que tener en cuenta su elevado potencial angiogénico. Conclusiones: El PRP, dadas las características de producción y aplicación, es considerado por la AEMPS como un medicamento de dispensación bajo prescripción médica restringida, por lo que los servicios de farmacia hospitalaria deberían, cuando menos, supervisar su gestión y manipulación (AU)

Introduction: Platelet-Rich Plasma (PRP) is autologous plasma with higher concentration of platelet than basal level, because of an extracting and concentration process. PRP therapeutical use, as osteinductor role, is a controversial issue, due to there are no clinical studies with rigorous design and no firm conclusions can be drawn regarding its uses. Propose: To provide information about methods to obtain PRP, legal considerations about its extraction and use, molecular mechanism of action, as well as available evidence about security and tolerance. Results: PRP can be obtained by manual procedures (opened technique) or disposable kits (closed technique), the latter being medical devices classified as type IIa. AEMPS considers PRP as a drug, establishing some minimum requirements to guarantee safety, traceability, pharmacovigilance and information. PRP provides ideal qualities to play a powerful osteoinductor role to speed up fracture healing or to produce an efficiently and quickly osseointegration of different bone implants, due to the high growth factors content. Infiltration tolerance is generally good, however, it has to be taken into account its great angiogenical potential. Conclusions: In view of its production and application characteristics, PRP is considered as a drug on restricted medical prescription by the AEMPS, so pharmacy department must, at least, supervise its management and handling (AU)
