Lista de comprobación para la atención farmacéutica del paciente con enfermedad pulmonar intersticial (CheckEPID): un consenso basado en el método Delphi / Checklist for Pharmaceutical Care of the Patient with interstitial lung disease (CheckEPID): A Delphi-based consensus

Objetivo desarrollar una lista de comprobación para facilitar la atención farmacéutica al paciente con enfermedad pulmonar intersticial que requieren o están en tratamiento con antifibróticos. Método 5 especialistas en farmacia hospitalaria desarrollaron un listado inicial de 37 ítems divididos en 4 bloques: 1) primera visita del paciente, que incluía datos generales del paciente y datos del primer tratamiento; 2) visitas de seguimiento, valorando aspectos del seguimiento del tratamiento con nintedanib o pirfenidona; 3) telefarmacia, consistente en la evaluación de la inclusión de pacientes en un programa de este tipo, evolución de la enfermedad e identificación del contacto con el servicio de farmacia y 4) tratamiento no farmacológico e información al paciente. Para decidir su potencial inclusión en el listado de comprobación se realizaron 2 rondas del Delphi en las que los panelistas tenían que valorar de cada ítem propuesto su grado de acuerdo con su «utilidad», que fue el criterio determinante para su inclusión y su «aplicabilidad». Resultados se contactó con 48 farmacéuticos hospitalarios, 30 (63%) aceptaron por escrito participar, 28 (58%) completaron la primera ronda del Delphi y 27 (56%) completaron la segunda ronda. Después de la primera ronda el cuestionario se modificó y quedó constituido por 40 ítems. De los 40 ítems evaluados tras las 2 rondas del Delphi, hubo 2 que, basados en la utilidad, los participantes del Delphi no alcanzaron el consenso para su inclusión en el listado: el referido a «Antecedentes de intervención quirúrgica, específicamente cirugía abdominal en las últimas 4 semanas» (finalmente mantenido en el listado por su implicación en la indicación de nintedanib) y el de realizar recomendaciones sobre «Relajación». En 2 de los ítems no se alcanzó consenso sobre su aplicabilidad: «Estratificación del paciente según el modelo del paciente crónico de la SEFH» y «Recogida de resultados comunicados por el paciente».

[Translated article] Checklist for the pharmaceutical care of patients with interstitial lung disease (CheckEPID): A Delphi-based consensus.

OBJECTIVE: To develop a checklist to facilitate pharmaceutical care for patients with interstitial lung disease who require or are undergoing treatment with antifibrotic drugs. METHOD: Five hospital pharmacists developed an initial list of 37 items divided into 4 blocks: (1) First visit, which included general patient data and data from the first treatment; (2) follow-up visits, assessing aspects of the follow-up of the treatment with nintedanib or pirfenidone; (3) telepharmacy, consisting of the evaluation of the inclusion of patients in a program of this type, course of the disease, and identification of the contact with the pharmacy service; (4) non-pharmacological treatment and patient information. To decide its potential inclusion in the checklist, 2 rounds of the Delphi were carried out in which the panelists had to assess the degree of agreement of each proposed item according to its "utility", which was the determining criterion for its inclusion, and its "applicability". RESULTS: Forty-eight hospital pharmacists were contacted, 30 (63%) agreed in writing to participate, 28 (58%) completed the first round of the Delphi, and 27 (56%) completed the second round. After the first round of the Delphi, the questionnaire was amended and comprised 40 items. Of the 40 items evaluated after the 2 rounds of the Delphi, there were 2 that, based on utility, the participants did not reach consensus for inclusion in the checklist: the one referring to "History of surgical intervention, specifically abdominal surgery in the last 4 weeks" (finally kept on the checklist due to its involvement in the indication of nintedanib) and to make recommendations on "Relaxation". No consensus was reached on their applicability for 2 of the items: "Patient stratification according to the Spanish Society of Hospital Pharmacy (SEFH) chronic patient model" and "Collection of Results Reported by the Patient". CONCLUSIONS: The management of patients with ILD and/or pulmonary fibrosis is complex and requires a multidisciplinary approach where the hospital pharmacist plays a key role, especially, although not only, in monitoring drug treatment. We believe that this checklist can contribute from pharmaceutical care to improving the integrated care of patients with ILD who require or are undergoing treatment with antifibrotic drugs.

[Sleep disorders related to HIV treatment.] / Trastornos en la calidad del sueño asociados a los inhibidores de la integrasa en el tratamiento del VIH.

OBJECTIVE: HIV Clinical Guidelines have positioned integrase inhibitors recently as first-line treatment. However, two of these drugs have also been associated with adverse side effects on the central nervous system, especially with sleep disturbances. The objective was to analyse the influence of bictegravir and dolutegravir on the sleep quality in HIV patients. METHODS: An observational, cross-sectional study was carried out between December 2020 and January 2021 in HIV patients attended in a pharmacy care clinic. Demographic and adherence variables were collected. Sleep quality was measured using the Pittsburgh questionnaire or PSQI. We classified patients into two groups: patients with bictegravir or dolutegravir in their treatment (study group) and the rest (control group). The influence of the variables collected on the PSQI result was analysed using the Chi-Square test for categorical variables and the student t-test or Mann-Whitney U test for continuous variables. RESULTS: One hundred and nineteen patients were included. 64% in the study group and 67% in the control group suffered from sleep disorders according to the PSQI questionnaire (p=0.788). Neither were statistical differences found when the different components of sleep were analysed between the two groups. CONCLUSIONS: A high percentage of patients, regardless of whether their treatment includes bictegravir or dolutegravir, have problems with their sleep quality. We didn't find a correlation between sleep quality and treatment with bictegravir or dolutegravir compared to the other treatments.

OBJETIVO: Los inhibidores de la integrasa se han posicionado recientemente en todas las Guías Clínicas de VIH como tratamiento antirretroviral de primera línea para el VIH. Sin embargo, dos de estos fármacos se han asociado también a efectos adversos a nivel del sistema nervioso central, concretamente con alteraciones del sueño. El objetivo del trabajo fue analizar la influencia de bictegravir y dolutegravir en la calidad del sueño en personas que viven con VIH (PVIH). METODOS: Se realizó un estudio observacional y transversal entre los meses de diciembre de 2020 y enero de 2021 en las PVIH de las consultas de atención farmacéutica del hospital. Se recogieron variables demográficas y de adherencia. La calidad del sueño se midió mediante el Cuestionario de Pittsburgh o PSQI. Las PVIH se clasificaron en 2 grupos: el grupo estudio, constituido por participantes con bictegravir o dolutegravir en su tratamiento, y el grupo control, integrado por el resto de PVIH. Se analizó la influencia de las variables recogidas sobre el resultado del PSQI mediante la prueba de chi cuadrado/odds ratio para variables categóricas y el de t de Student o U de Mann Whitney para variables continuas. RESULTADOS: Se incluyeron 119 PVIH, de las cuales un 64% en el grupo estudio y un 67% en el grupo control sufrían trastornos del sueño según el PSQI (p=0,788). Tampoco hubo diferencias estadísticamente significativas cuando se compararon los diferentes componentes del sueño entre los dos grupos. CONCLUSIONES: Un elevado porcentaje de PVIH, independientemente de si el TAR incluye bictegravir o dolutegravir, tienen problemas relacionados con la calidad del sueño. No se encuentra correlación entre la calidad del sueño y el tratamiento con bictegravir o dolutegravir comparado con el resto de tratamientos.

Prevalencia de la infección por el VHC en un área sanitaria de Madrid: el primer paso para la microeliminación / Prevalence of HCV infection in a health area of Madrid (Spain): The first step towards microelimination

OBJETIVO: Estimar la prevalencia de la infección por VHC en la población general de un área sanitaria a través de una intervención en Atención Primaria, diferenciando entre nuevos diagnósticos e infecciones previamente diagnosticadas pero no tratadas. MÉTODOS: Se seleccionaron participantes mediante un cuestionario de evaluación de riesgo, realizando un test rápido a todos aquellos con alguna respuesta afirmativa y a todos los mayores de 50 años. Las pruebas positivas se confirmaron en el laboratorio mediante determinación de anticuerpos frente al VHC por enzimoinmunoensayo de micropartículas quimioluminiscente y determinación de la viremia. RESULTADOS: Del total de 7.991 participantes, el 36,2% presentó cuestionario de riesgo para VHC. Se realizaron 4.717 test, encontrando una proporción de anti-VHC de 0,65% en la población cribada, quedando en 0,46% de infecciones activas. El 51,9% de las personas con test positivo tenían un diagnóstico previo conocido pero no habían recibido tratamiento, por no ser conscientes de ello o no encontrarse vinculados al sistema sanitario, y el 19,2% tuvo un resultado positivo por primera vez. La prevalencia de infección oculta fue mayor en hombres, mayores de 50 años, y personas procedentes de Europa del Este. CONCLUSIÓN: Encontramos una prevalencia de infecciones activas superior a la descrita recientemente a nivel nacional, y con mayor porcentaje de pacientes nuevamente diagnosticados que en trabajos similares en otras áreas. Estas diferencias justifican la necesidad de realizar evaluaciones locales de la prevalencia de infección por VHC en cada una de las áreas de salud donde se plantee implementar y monitorizar un programa de microeliminación

OBJECTIVE: To estimate the prevalence of HCV infection in the general population of a health area through an intervention in Primary Care, differentiating between new diagnoses and infections previously diagnosed but not treated. METHODS: Participants were selected through a risk assessment questionnaire, with all those who gave at least one affirmative answer and all those over 50 years of age undergoing a rapid test. Positive tests were confirmed in the lab by determination of anti-HCV antibodies by chemiluminescent microparticle immunoassay and determination of viraemia. RESULTS: Of the 7,991 participants, 36.2% presented a positive HCV risk questionnaire. 4,717 tests were performed, finding an anti-HCV percentage of 0.65% in the screened population, with 0.46% of active infections. Among the individuals with a positive test result, 51.9% had a known prior diagnosis but had not received treatment, because they were not aware of it or were not linked to the health system, and 19.2% had a positive result for the first time. The prevalence of hidden infection was higher in men, those over 50 years of age and people from Eastern Europe. CONCLUSION: We found a prevalence of active infections higher than recently described nationwide, and a higher percentage of newly diagnosed infections than recent similar studies in other areas. These differences justify the need to perform local assessments of the prevalence of HCV infection in each of the health areas where it is planned to implement and monitor a microelimination programme

Satisfaction and knowledge among patients with HIV after switching from tenofovir to tenofovir alafenamide in regimens containing emtricitabine and rilpivirine / [Grado de satisfacción y conocimiento de pacientes positivos para HIV ante el cambio de tenofovir a tenofovir-alafenamida en tratamientos con emtricitabina y rilpivirina].

Introduction: Satisfaction and knowledge among patients with HIV after switching from tenofovir to tenofovir/alafenamide remain unexplored. Given that both parameters are associated with better health outcomes it is relevant to measure them in patients during routine clinical practice. Objective: To evaluate the degree of knowledge and satisfaction in patients who had their antiretroviral regimen switched from rilpivirine (RPV)/emtricitabine (FTC)/TDF to RPV/FTC/TAF. Materials and methods: We conducted a prospective study in a third-level hospital between September, 2018, and November, 2018. We included patients who had previously been treated with RPV/FTC/TDF and collected their RPV/FTC/TAF treatment in the second visit. A 5-point Likert-type agreement/disagreement scale was used to assess satisfaction and knowledge regarding the medication switch. Results: We included 116 patients in the study of whom 75% were satisfied and 64% had a high-level of knowledge. Young patients were less satisfied with the way in which the change was explained (p=0.0487). Concerning the new medication, the patients were better informed about its renal (85% of them) and bone benefits (82%) than about its adverse effects on the lipid profile (40%). Conclusions: The patients were generally satisfied with the change in medication and well nformed about the dosage and advantages of TAF over TDF, but less well informed about the possible adverse effects of TAF.

Introducción. La satisfacción y el conocimiento del cambio de tenofovir por tenofovir-alafenamida en pacientes con HIV no se han estudiado aún. Estos dos parámetros se relacionan con mejores resultados en salud y, por lo tanto, es importante medirlos durante la práctica clínica habitual. Objetivo. Evaluar el grado de conocimiento y satisfacción de los pacientes positivos para HIV ante el cambio de tratamiento antirretroviral con rilpivirina, emtricitabina y tenofovir (RPV-FTC-TDF) por rilpivirina, emtricitabina y tenofovir-alafenamida (RPV-FTC-TAF). Materiales y métodos. Se llevó a cabo un estudio prospectivo en un hospital de tercer nivel entre los meses de septiembre y noviembre de 2018. Se incluyeron pacientes previamente tratados con RPV-FTC-TDF que acudían por segunda vez a consulta para recibir el tratamiento con RPV-FTC-TAF. La satisfacción y el grado de conocimiento se analizaron mediante nueve preguntas, usando una escala de tipo Likert de 5 puntos para evaluar el grado de acuerdo. Resultados. Se incluyeron 116 pacientes en el estudio. El 75 % de ellos se mostró satisfecho con el cambio y se consideró que el 64 % conocía lo que implicaba. Los pacientes jóvenes se mostraron menos satisfechos con el modo en que se les explicó el cambio (p=0,0487). Los pacientes estaban mejor informados sobre las ventajas renales (85 % de conocimiento) y óseas (82 %) de la nueva medicación, que sobre sus inconvenientes para el perfil lipídico (40 %). Conclusiones. En general, los pacientes se mostraron satisfechos con el cambio de medicación y conocían la posología del medicamento y las ventajas de la tenofovir-alafenamida frente al tenofovir, pero no sus posibles efectos adversos.

Interacciones de cobicistat y ritonavir en pacientes con VIH y sus consecuencias clínicas / Interactions of cobicistat and ritonavir in patients with HIV and its clinical consequences

INTRODUCCIÓN: La prescripción de tratamiento antirretroviral (TAR) que contiene potenciadores farmacocinéticos como ritonavir y cobicistat es frecuente. El objetivo de este estudio fue analizar las interacciones potenciales del TAR que incluyen estas moléculas en su formulación con la medicación domiciliaria del paciente, así como el manejo clínico de aquellas potencialmente graves. MÉTODOS: Estudio prospectivo en la consulta de atención farmacéutica de un hospital de tercer nivel entre enero y diciembre de 2018. Se incluyeron en el estudio aquellos pacientes VIH + con un TAR que contuviera cobicistat o ritonavir. Se analizaron las interacciones potenciales entre el TAR y la medicación concomitante en tres bases de datos (Micromedex(R), Drugs.com y Liverpool), se detallaron las intervenciones realizadas, y se analizaron las reacciones adversas encontradas. RESULTADOS: Se incluyeron 968 pacientes con un total de 2.148 prescripciones (274 principios activos diferentes). Se realizaron un total de 86 intervenciones relativas a interacciones potenciales en los pacientes. Las más frecuentes fueron sustituciones de tratamientos corticoideos, supensiones de tratamiento y monitorizaciones más estrechas. Se analizaron un total de doce sospechas de reacción adversa. El grado de concordancia en la clasificación de la gravedad de las interacciones para cobicistat y ritonavir fue buena entre las tres bases de datos. Resultó destacable Micromedex(R) como la más completa por tener más principios activos registrados. CONCLUSIÓN: Las interacciones entre el TAR con potenciadores farmacocinéticos en su composición y la medicación concomitante es frecuente y requiere de una importante variedad de intervenciones. El chequeo de interacciones en distintas bases de datos es recomendable ya que pueden ocasionar reacciones adversas a medicamentos

INTRODUCTION: The prescription of antiretroviral treatment (ART) that contains pharmacokinetic enhancers such as ritonavir and cobicistat is frequent. The objective of this stdy was to analyze the potential interactions of ART that include these molecules in their formulation with the patient's home medication, as well as the clinical management of those potentially serious. METHODS: Prospective study conducted in the pharmacy care clinic of a third level hospital between January and December of 2018. Those HIV+patients with an ART containing cobicistat or ritonavir were included in the study. Potential interactions between ART and concomitant medication were analysed in three databases (Micromedex(R), Drugs.com and Liverpool), the interventions carried out were detailed, and adverse drug reactions analysed. RESULTS: 968 patients were included with a total of 2,148 prescriptions (274 different medications). A total of 86 interventions were performed regarding potential interactions in patients. The most frequent were substitutions of corticoid treatments, treatment suspensions and closer monitoring of treatments. A total of possible adverse drug reactions were analysed. The degree of agreement in the severity classification of the interactions for cobicistat and ritonavir was good among the three databases. It was remarkable Micromedex(R) as the most complete because it has more registered medications. CONCLUSIÓN: The interactions between ART with pharmacokinetic enhancers in its composition and concomitant medication is frequent and requires a significant variety of interventions. The check of interactions in different databases is recommended since they can cause adverse drug reactions

Usability and Acceptability of a Comprehensive HIV and Other Sexually Transmitted Infections Prevention App.

The Preparadxs app was designed to enhace the prevention of the HIV and other sexually transmitted infections transmission through the empowerment of the user. The purpose of this study is to determine the usability and perception about the app among real users. In this prospective cross-sectional study all app end-users were asked to answer the System Usability Scale and question regarding app capability to reduce sexually transmitted infections in the future. Influence of several variables (gender identity, educational level and digital native condition) was explored. A total of 69 users answered the survey during study period. Most of them were male and had university studies. Final usability score was 80,8 points which means a good, near excellent usability. No differences in usability scores were observed regarding to gender identity, native condition or educational level. Most users were strongly agree (56,5%) or agree (28,9%) with app potential to reduce the incidence of HIV and other STIs in the future.

[Adherence to entecavir for chronic hepatitis B and correlation with effectiveness]. / Relación entre adherencia a entecavir y efectividad en pacientes con hepatitis B crónica.

PURPOSE: to evaluate adherence of patients with chronic hepatitis B initiated on entecavir as first-line treatment and to correlate adherence with effectiveness. METHODS: observational retrospective study performed between January 2007 and June 2013. Patients treated with entecavir for at least one year were included. A patient was considered to be adherent if median adherence was ≥ 95%. Virological response (HBV DNA < 20UI/ml by Polymerase Chain Reaction), biochemical response (normalized level of alanine amino transferase [AAT]) and serological response (loss of hepatitis B surface antigen [HBsAg]) was assessed at month 12. RESULTS: 85 patients were included. The median adherence rate was 94.2 (SD 12.8)%. 85.7% of the adherent patients achieved a virological response in contrast with 71.4% of the nonadherent patients (OR:2,40; IC95%:0,60-9,54;p = 0,19). 87.9% of the adherent patients and 85.7% of the nonadherent patients showed normalized level of AAT (OR:1,21; IC95%:0,22- 6,60;p = 0,56). Two adherent patients showed clearance of hepatitis B surface antigen. CONCLUSION: the median adherence is not high. Nonadherent patients have a trend towards a higher rate of virological failure so it is necessary to promote improved adherence to treatment.

Objetivo: evaluar la adherencia de pacientes con hepatitis B cronica que inician tratamiento con entecavir como primera linea, y relacionarla con la efectividad. Métodos: estudio observacional retrospectivo realizado entre enero de 2007 y junio de 2013. Se incluyeron pacientes tratados con entecavir al menos durante un ano. Se considero un paciente adherente si la adherencia media era ≥ 95%. Se evaluo la respuesta virologica (ADN VHB < 20UI/ml mediante la reaccion en cadena de la polimerasa), bioquimica (normalizacion de alanina aminotranferasa [AAT]) y serologica (perdida del antigeno de superficie [HBsAg]) a los 12 meses. Resultados: se incluyeron 85 pacientes. La adherencia media fue 94,2 (DE 12,8)%. El 85,7% de los pacientes adherentes lograron respuesta virologica vs. el 71,4% de los de no adherentes (OR:2,40; IC95%:0,60­9,54; p=0,19). El 87,9% de los pacientes adherentes y el 85,7% de los no adherentes normalizaron niveles de AAT (OR:1,21; IC95%:0,22- 6,60; p=0,56). Solo dos pacientes adherentes mostraron perdida del HBsAg. Conclusión: la adherencia media no es alta. Los pacientes sin adherencia presentan una mayor tendencia al fracaso virologico, por lo que es necesario fomentar una mejora en la adherencia a los tratamientos.

Purpose: to evaluate adherence of patients with chronic hepatitis B initiated on entecavir as first-line treatment and to correlate adherence with effectiveness. Methods: observational retrospective study performed between January 2007 and June 2013. Patients treated with entecavir for at least one year were included. A patient was considered to be adherent if median adherence was ≥ 95%. Virological response (HBV DNA < 20UI/ml by Polymerase Chain Reaction), biochemical response (normalized level of alanine amino transferase [AAT]) and serological response (loss of hepatitis B surface antigen [HBsAg]) was assessed at month 12. Results: 85 patients were included. The median adherence rate was 94.2 (SD 12.8)%. 85.7% of the adherent patients achieved a virological response in contrast with 71.4% of the nonadherent patients (OR:2,40; IC95%:0,60–9,54;p = 0,19). 87.9% of the adherent patients and 85.7% of the nonadherent patients showed normalized level of AAT (OR:1,21; IC95%:0,22- 6,60;p = 0,56). Two adherent patients showed clearance of hepatitis B surface antigen. Conclusion: the median adherence is not high. Nonadherent patients have a trend towards a higher rate of virological failure so it is necessary to promote improved adherence to treatment (AU)
