Non-valvular atrial fibrillation in patients on peritoneal dialysis, prevalence, treatment and professionals involved.

Atrial fibrillation is the most frequent chronic arrhythmia in patients with chronic kidney disease. Oral anticoagulation with vitamin K antagonists and now direct oral anticoagulants have been and are the fundamental pillars for the prevention of thromboembolic events. However, there are no randomized clinical trials on the risk-benefit profile of oral anticoagulation in patients with chronic kidney disease stage 5 on peritoneal dialysis and there is little evidence in the literature in this population. The objective of our study was to know the prevalence, treatment and professionals involved in the management of atrial fibrillation in peritoneal dialysis patients. For this purpose, we performed a descriptive analysis through a survey sent to different peritoneal dialysis units in Spain. A total of 1,403 patients on peritoneal dialysis were included in the study, of whom 186 (13.2%) had non-valvular atrial fibrillation. In addition, the assessment of the scores of thromboembolic and bleeding risks for the indication of oral anticoagulation was mainly carried out by the cardiologist (60% of the units), as well as its prescription (cardiologist 47% or in consensus with the nephrologist 43%). In summary, patients on peritoneal dialysis have a remarkable prevalence of non-valvular atrial fibrillation. Patients frequently receive oral anticoagulation with vitamin K antagonists, as well as direct oral anticoagulants. The data obtained regarding the scores used for the assessment of thromboembolic and bleeding risk, treatment and involvement by Nephrology indicates that there is a need for training and involvement of the nephrologist in this pathology.

Fibrilación auricular no valvular en pacientes en diálisis peritoneal: prevalencia, tratamiento y profesionales implicados / Non-valvular atrial fibrillation in patients on peritoneal dialysis: prevalence, treatment and professionals involved

La fibrilación auricular (FA) es la arritmia crónica más frecuente en pacientes con enfermedad renal crónica (ERC). La anticoagulación oral con antagonistas de la vitamina K (AVK) y actualmente los anticoagulantes orales de acción directa (ACOD) han sido el pilar fundamental para la prevención de eventos tromboembólicos. Sin embargo, no existen ensayos clínicos aleatorizados de su perfil riesgo-beneficio en pacientes con ERC estadio 5 en diálisis peritoneal (DP) y son pocas las evidencias en la literatura sobre esta población. El objetivo del estudio fue conocer la prevalencia, tratamiento y profesionales implicados en el manejo de la FA en DP en nuestro entorno mediante el análisis descriptivo de una encuesta enviada a diferentes unidades de DP de España. Se incluyeron en el estudio 1.403 pacientes en programa de DP, de los cuales 186 (13,2%) presentaban FA no valvular (FANV). Además, observamos que la valoración de los scores para el inicio del tratamiento anticoagulante la realizaba mayoritariamente el cardiólogo (60% de los centros), así como la prescripción de anticoagulación (cardiólogo 47% o en conjunto con el nefrólogo 43%). En conclusión, los pacientes en DP presentan una notable prevalencia de FANV. Reciben frecuentemente anticoagulación oral (ACO) con AVK, así como con ACOD. Los datos obtenidos respecto a las escalas utilizadas para la valoración de riesgo tromboembólico y de sangrado, tratamiento e implicación por parte de Nefrología indican que existe una necesidad de formación e involucramiento del nefrólogo en esta patología.(AU)

Situación actual de los anticoagulantes orales de acción directa en atención primaria de España. Posicionamiento de SEMERGEN en 2023 / Current situation of direct oral anticoagulants in primary care in Spain: Positioning of SEMERGEN in 2023

La anticoagulación oral es clave para disminuir el riesgo de ictus en la fibrilación auricular. Aunque clásicamente los antagonistas de la vitaminaK (AVK) se han empleado para este fin, han sido ampliamente superados por los anticoagulantes orales de acción directa (ACOD), como lo demuestran las evidencias provenientes de los ensayos clínicos, estudios de vida real y poblacionales. De hecho, todas las guías de práctica clínica recomiendan su uso de manera preferencial sobre los AVK. Sin embargo, en España la prescripción de los ACOD está subordinada a un visado de inspección que recoge las condiciones clínicas definidas en el Informe de Posicionamiento Terapéutico de la Agencia Española del Medicamento, y que todavía impone importantes restricciones a su uso, limitando los beneficios del empleo de los ACOD en los pacientes con fibrilación auricular (FA), y generando además inequidades entre las diferentes comunidades autónomas. De hecho, el empleo de los ACOD en España es muy inferior a los países de nuestro entorno. Esto ha provocado que en otros países ha disminuido la incidencia de ictus isquémico a nivel poblacional, junto con una reducción del coste por paciente con FA, pero en España este descenso ha sido discreto. Por todo ello, y en aras de la sostenibilidad del sistema sanitario, pedimos la eliminación del visado para que los ACOD se puedan prescribir de acuerdo a las recomendaciones realizadas por las guías. Además, también apostamos por el refuerzo de la formación y de las decisiones consensuadas con el paciente, siendo el médico de familia un actor clave en la protección del paciente con FA.(AU)

Oral anticoagulation is the key to reduce the risk of stroke in atrial fibrillation. Although vitaminK antagonists (VKA) have classically been used for this purpose, they have been largely overcome by direct oral anticoagulants (DOAC), as demonstrated by evidence from clinical trials, real-life and population studies. In fact, all clinical practice guidelines recommend their use preferentially over VKA. However, in Spain the prescription of DOAC is subordinated to an inspection visa that includes the clinical conditions defined in the Therapeutic Positioning Report of the Spanish Medicines Agency, and that still imposes important restrictions on their use, limiting the benefits of using DOACs in patients with atrial fibrillation (AF), and also generating inequalities between the different autonomous communities. In fact, the use of DOAC in Spain is much lower than that observed in neighboring countries. This has made that while in other countries the incidence of ischemic stroke has decreased at the population level, along with a reduction in the cost per patient with AF, in Spain this decrease has been modest. For all these reasons, and for assuring the sustainability of the health care system, we ask for the elimination of the visa so that DOAC can be prescribed according to the recommendations made by the guidelines. In addition, we are also committed to reinforce medical education and decisions made by consensus with the patient, with the primary care physician acquiring a key role in the protection of the patient with AF.(AU)

Evidence of the association between increased use of direct oral anticoagulants and a reduction in the rate of atrial fibrillation-related stroke and major bleeding at the population level (2012–2019) / Evidencia a nivel poblacional de la asociación entre el aumento del uso de anticoagulantes orales directos y una reducción de la incidencia de ictus y hemorragias mayores relacionados con fibrilación auricular (2012-2019)

Background: The introduction of direct-acting oral anticoagulants (DOACs) has shown to decrease atrial fibrillation (AF)-related stroke and bleeding rates in clinical studies, but there is no certain evidence about their effects at the population level. Our aim was to assess changes in AF-related stroke and major bleeding rates between 2012 and 2019 in Andalusia (Spain), and the association between DOACs use and events rates at the population level. Methods: All patients with an AF diagnosis from 2012 to 2019 were identified using the Andalusian Health Population Base, that provides clinical information on all Andalusian people. Annual ischemic and hemorrhagic stroke, major bleeding rates, and used antithrombotic treatments were determined. Marginal hazard ratios (HR) were calculated for each treatment. Results: A total of 95,085 patients with an AF diagnosis were identified. Mean age was 76.1±10.2 years (49.7% women). An increase in the use of DOACs was observed throughout the study period in both males and females (p<0.001). The annual rate of ischemic stroke decreased by one third, while that of hemorrhagic stroke and major bleeding decreased 2–3-fold from 2012 to 2019. Marginal HR was lower than 0.50 for DOACs compared to VKA for all ischemic or hemorrhagic events. Conclusions: In this contemporary population-based study using clinical and administrative databases in Andalusia, a significant reduction in the incidence of AF-related ischemic and hemorrhagic stroke and major bleeding was observed between 2012 and 2019. The increased use of DOACs seems to be associated with this reduction.(AU)

Introducción: La introducción de los anticoagulantes orales de acción directa (ACOD) ha demostrado disminuir las tasas de accidentes cerebrovasculares y hemorragias relacionados con fibrilación auricular (FA) en estudios clínicos, pero no hay tanta evidencia sobre sus efectos a nivel poblacional. Nuestro objetivo fue evaluar los cambios en la incidencia de ictus y hemorragias mayores relacionados con FA entre 2012 y 2019 en Andalucía (España), y estudiar la asociación entre el uso de ACOD y estos eventos a nivel poblacional. Métodos: Se incluyeron pacientes con diagnóstico de FA entre los años 2012 y 2019 en la Base de Población Sanitaria de Andalucía, que proporciona información clínica de todos los andaluces. Se determinaron los accidentes cerebrovasculares isquémicos y hemorrágicos anuales, las tasas de sangrado mayor y los tratamientos antitrombóticos utilizados. Se estimaron los hazard ratio para cada tratamiento. Resultados: Se identificaron un total de 95.085 pacientes con diagnóstico de FA. La edad media fue de 76,1±10,2 años (49,7% mujeres). Se observó un aumento en el uso de ACOD a lo largo del período de estudio, tanto en varones como en mujeres (p<0,001). La tasa anual de ictus isquémico disminuyó en un tercio, mientras que la de ictus hemorrágico y hemorragia mayor se redujo de 2 a 3 veces entre 2012 y 2019. Los hazard ratio fueron inferiores a 0,50 para los ACOD en comparación con los antivitamina K para todos los eventos isquémicos o hemorrágicos. Conclusiones: En este estudio poblacional contemporáneo, se observó, utilizando bases de datos clínicas y administrativas de Andalucía, una reducción significativa en la incidencia de ictus isquémico y hemorrágico, y hemorragia mayor relacionados con FA entre los años 2012 y 2019. El mayor uso de ACOD parece estar asociado con esta reducción.(AU)

Manejo odontológico del paciente en tratamiento de anticoagulante oral sometido a cirugía oral: una revisión narrativa / Stomatological management of anticoagulated patients undergoing oral surgery: a narrative review

Resumen Los pacientes que se encuentran bajo tratamiento de anticoagulantes orales, presentan alteraciones en distintas etapas de la hemostasia, lo que conlleva a tener implicancias y consideraciones médico/quirúrgicas durante su atención. En la actualidad, no existe un consenso en relación con el manejo odontológico de estos pacientes que serán sometidos a procedimientos quirúrgicos, llevando a protocolos clínicos que siguen diversas posturas, como la de disminuir la ingesta farmacológica del anticoagulante, sustituir con heparina y la de mantener el tratamiento bajo control. Objetivo Establecer el manejo estomatológico del paciente que se encuentra en tratamiento de anticoagulante oral mediante una revisión profunda de la literatura Materiales y método Se realizó una búsqueda de revisión bibliográfica manualmente de artículos indexados a las bases de datos de PUBMED y EBSCO que correspondiesen a las palabras "cirugía bucal", "anticoagulantes", "atención dental" y "hemorragia oral". En cuanto a los criterios de inclusión, se consideraron revisiones bibliográficas, estudios observacionales, ensayos clínicos, guías, revisiones sistemáticas y metaanálisis publicados entre noviembre de 2005 y 2022, en idiomas inglés o español. Conclusiones Existen múltiples protocolos para la atención del paciente anticoagulado que será sometido bajo procedimiento de cirugía oral menor. Es importante considerar el anticoagulante utilizado, motivo, control de este, el procedimiento a realizar en el paciente y medidas hemostáticas tanto intra como postoperatorias por realizar, tras analizar lo anterior, se advierte que disminuir la ingesta del fármaco para realizar el procedimiento, puede ser más perjudicial al paciente como al clínico, por lo tanto se sugiere mantener el tratamiento antitrombótico y realizar un correcto manejo médico/quirúrgico.

Abstract Patients undertaking oral anticoagulant treatment may experience alterations in different stages of hemostasis, which lead to medical/surgical implications and considerations during their care. Currently, there is no consensus regarding the dental management of these patients, as they go through surgical procedures. This leads to clinical protocols that follow numerous approaches, such as reducing the pharmacological intake of the anticoagulant, replacing it with heparin, and maintaining the controlled treatment. Objective: To establish the stomatological management of the patient undergoing oral anticoagulant treatment through an in depth review of the literature. Materials and Method: A manual bibliographic review search of articles indexed to the PUBMED and EBSCO databases corresponding to the words "oral surgery", "oral bleeding", "anticoagulants" and "dental management" was performed. Regarding the inclusion criteria: bibliographic reviews, observational studies, clinical trials, guidelines, systematic reviews, and meta-analyses published between November 2005 and 2022, in English or Spanish, were considered. Conclusion: There are multiple protocols for the care of the anticoagulated patient who will undergo a minor oral surgery procedure. It is important to reflect on the anticoagulant used, the reason for it, its supervision, the surgical procedure that will be undertaken by the patient, and both intraoperative and postoperative hemostatic measures to be implemented. After analyzing the above, it is noted that reducing the intake of the drug to perform the surgical procedure may be harmful to the patient and to the clinician, therefore it is suggested to maintain the antithrombotic treatment and carry out a correct medical/surgical management.

Manejo perioperatorio de medicación anticoagulante y antiagregante antiplaquetaria en radiología intervencionista / Perioperative management of anticoagulants and antiplatelets agents in interventional radiology

Resumen El número de personas en tratamiento con fármacos anticoagulantes o antiplaquetarios está en crecimiento constante debido al aumento de la supervivencia de los pacientes con fibrilación auricular, válvulas cardiacas mecánicas o que han sufrido un evento isquémico o trombótico agudo. Cuando estos pacientes necesitan un procedimiento radiológico intervencionista que acarrea riesgo de sangrado, es necesario analizar el riesgo trombótico del paciente al interrumpir la medicación frente al riesgo hemorrágico del procedimiento para tomar la decisión más adecuada en cada caso. Por tanto, es una decisión individualizada y supone un desafío para los/as radiólogos/as que realicen estas técnicas. Nuestro objetivo en esta revisión es mostrar las recomendaciones actuales sobre el manejo perioperatorio de la medicación anticoagulante y antiplaquetaria, adaptada al intervencionismo radiológico.

Abstract The number of people treated with anticoagulant or antiplatelet agents is constantly growing due to the increased survival of patients with atrial fibrillation, mechanical cardiac valves or who have suffered an acute thrombotic or ischemic event. When these patients need an interventional radiological procedure that carries a risk of bleeding, it is necessary to analyze the thrombotic risk of the patient when interrupting the medication against the hemorrhagic risk of the procedure, to make the most appropriate decision in each case. Therefore, it is an individualized decision, and it is a challenge for radiologists who perform these techniques. Our goal in this review is to update the current recommendations on the perioperative management of anticoagulant and antiplatelet agents, adapted to the radiological interventionism.

ACOD frente a AVK en pacientes con fibrilación auricular y bioprótesis: revisión sistemática y metanálisis / DOAC versus VKA in patients with atrial fibrillation and bioprosthetic valves: a systematic review and meta-analysis

Introducción y objetivos: Los anticoagulantes orales directos (ACOD) se han mostrado eficaces y seguros en pacientes con fibrilación auricular; sin embargo, los pacientes con FA y bioprótesis están infrarrepresentados en los ensayos clínicos, por lo que la evidencia en este grupo es menor. Nuestro objetivo fue analizar la seguridad y eficacia de los ACODs en esta población revisando la información existente en la literatura. Métodos: Se realizó una búsqueda y revisión sistemática con los ensayos clínicos aleatorizados y estudios observacionales comparativos desde 2017 a enero de 2022, que comparasen ACODs y antagonistas de vitamina K (AVK) en pacientes con FA y bioprótesis. Se utilizó la hazard ratio al 95% del intervalo de confianza para comparar ambos grupos en términos de mortalidad total y cardiovascular, ictus/embolia sistémica y hemorragia mayor. Se realizó un metanálisis combinando los resultados de los estudios incluidos. Resultados: Se incluyeron 12 estudios (un total de 30.283 pacientes). Los ACODs se asociaron a una reducción significativa del 9% de la mortalidad total (HR=0,91; IC95%, 0,85-0,97; p=0,0068; I2=8%), sin diferencias significativas en el riesgo de ictus/embolismo sistémico (HR=0,87; IC95%, 0,67-1,14; p=0,29; I2=45%) o hemorragia mayor (HR=0,82; IC95%, 0,67-1,00; p=0,054; I2=48.7%). Conclusiones: En pacientes con FA portadores de bioprótesis, los ACODs podrían asociarse a una reducción de la mortalidad total sin reducción de eficacia en la prevención de ictus/embolia sistémica o aumento del riesgo de hemorragia mayor.(AU)

Introduction and objectives: Direct oral anticoagulant (DOAC) therapy has been shown to be safe and effective in patients with atrial fibrillation (AF). However, outcomes in AF patients with bioprosthetic valves are unclear, as this population has been underrepresented in clinical trials. The aim of this study was to assess the safety and efficacy of DOACs in this population based on the existing published literature. Methods: A systematic search and review were conducted to identify randomized clinical trials and comparative observational studies published from 2017 to January 2022 that compared DOACs and vitamin K antagonists (VKAs) in AF patients with bioprosthetic valves. Hazard ratios (HR) were collected to compare the 2 treatments in terms of cardiovascular and all-cause mortality, stroke/systemic embolism, and major bleeding. A meta-analysis combining the results was performed. Results: We included 12 studies (30 283 patients). DOACs and VKAs were compared based on HRs at the 95% confidence interval. DOAC therapy was associated with a significant 9% reduction in all-cause mortality (HR, 0.91; 95%CI, 0.85-0.97; P=.0068; I2=8%), with no significant differences in the risk of stroke/systemic embolism (HR, 0.87; 95%CI, 0.67-1.14; P=.29; I2=45%) or major bleeding (HR, 0.82; 95%CI, 0.67-1.00; P=.054; I2=48.7%). Conclusions: DOAC therapy in AF patients with bioprosthetic valves may be associated with a significant reduction in all-cause mortality, with no reduction in the efficacy of stroke/systemic embolism prevention or increase in major bleeding risk.(AU)

Invasive fungal rhinosinusitis associated with COVID-19: Course changes and prognosis predictors / Rinosinusitis fúngica invasiva asociada con COVID-19: cambios clínicos y predictores de pronóstico

Background This study aimed to analyze the behavior of acute invasive fungal rhinosinusitis (AIFRS) associated with COVID-19 infection as there has been an increase in the rate of AIFRS cases in the last two years, and many reports connected this rising with the COVID-19 infection. We studied most factors that may impact the prognosis as a trial to find the most affecting factors to improve the outcomes. Methods It was a retrospective observational study that included cases from four tertiary referral institutions between November 2020 to February 2022. We included sixty-six patients who suffered from AIFRS associated with confirmed COVID-19. We observed the prognosis of all included patients with a six-month follow-up. We correlated the prognosis with many factors, such as demographic data, medical conditions, blood investigations, the features of fungal infections, and management. Results Forty-two patients (64%) survived after the AIFRS associated with COVID-19, and twenty-two patients (36%) died. High doses of corticosteroids with prolonged use were the main factors that affected the behavior of the AIFRS associated with COVID-19. HbA1c was a good predictor of the prognosis; a level less than 9.35% may indicate survival with 87.5% sensitivity. Conclusions According to this multi-center study, the mortality of the AIFRS associated with COVID-19 was high. The behavior was affected by glycemic control, the type of fungal species, and the type of antifungal therapy. Early surgical debridement, a combination of Amphotericin B with Voriconazole, and anticoagulants helped improve the prognosis. (AU)

Antecedentes Durante el periodo de la pandemia de COVID19, ha habido un aumento en la tasa de casos de rinosinusitis fúngica invasiva aguda (RSFIA), siendo cada vez más evidente la asociación entre ambas entidades. EL objetivo de este estudio ha sido analizar la evolución de los pacientes con rinosinusitis fúngica invasiva aguda asociado con la infección por COVID-19, analizando los factores determinantes en la evolución y pronóstico de la enfermedad. Métodos Fue un estudio observacional retrospectivo que incluyó casos de cuatro instituciones de referencia de tercer nivel entre noviembre de 2020 y febrero de 2022. Se incluyeron sesenta y seis pacientes que padecían RSFIA asociado a COVID-19 confirmado. Observamos el pronóstico de todos los pacientes incluidos con un seguimiento de seis meses. Correlacionamos el pronóstico con muchos factores, como los datos demográficos, las condiciones médicas, las investigaciones de sangre, las características de las infecciones fúngicas y el manejo. Resultados Cuarenta y dos pacientes (64%) sobrevivieron después de la RSFIA asociada a COVID-19, y veintidós pacientes (36%) fallecieron. Las dosis altas de corticoides con uso prolongado fueron los principales factores que afectaron el comportamiento de la RSFIA asociada a la COVID-19. HbA1c fue un buen predictor del pronóstico; un nivel inferior al 9,35 % puede indicar supervivencia con una sensibilidad del 87.5%. Conclusiones Según este estudio multicéntrico, la mortalidad de la RSFIA asociada a la COVID-19 fue alta. El comportamiento se vio afectado por el control glucémico, el tipo de especie fúngica y el tipo de terapia antifúngica. El desbridamiento quirúrgico temprano, una combinación de Amphotericin B con Voriconazole y anticoagulantes ayudaron a mejorar el pronóstico. (AU)

Outcomes of recurrent stroke in patients with atrial fibrillation according to presumed etiology / Desfecho de AVC recorrente em pacientes com fibrilação atrial de acordo com etiologia presumida

Abstract Background Atrial fibrillation (AF) is a potent risk factor for stroke. The presence of competing etiologies can modify disease outcomes and demand different treatment strategies. Objective The primary purpose of the study was to examine the differences in outcomes for patients with AF admitted with a recurrent stroke, stratified according to the presumed etiology of the stroke. Methods We analyzed AF patients admitted for a recurrent ischemic stroke in an academic comprehensive stroke center. Recurrent strokes were categorized as "Cardioembolic", meaning AF without any competing mechanism, versus "Undetermined" etiology due to competing mechanisms. We used logistic regression to test the association between recurrent stroke etiology and favorable outcome (discharge home), after accounting for important covariates. Results We included 230 patients, with a mean age 76.9 (SD ± 11.3), 52.2% male, median National Institute of Health Stroke Scale (NIHSS) score of 7 (IQR 2-16). Patients with cardioembolic stroke (65.2%) had higher median NIHSS 8.5 (3-18) versus 3 (1-8) and were more likely to be treated with reperfusion therapies. The favorable outcome was reached by 64 patients (27.8%), and in-hospital mortality was 15.2% overall. After adjustment, there was no difference in outcome between patients with cardioembolic versus undetermined stroke etiology (odds ratio for discharge home: 1.41; 95% CI: 0.65-3.15). Conclusions In this single-center sample of AF patients with history of stroke, there was no difference in discharge outcomes between those with cardioembolic and those with undetermined stroke etiology. This question warrants examination in larger samples to better understand the importance of the stroke mechanism and secondary prophylaxis.

Resumo Antecedentes Fibrilação atrial (FA) é um fator de risco importante para AVC. A presença de mecanismos concorrentes para o AVC pode modificar o desfecho e demandar estratégias de tratamento diferentes. Objetivo O objetivo primário do estudo foi examinar diferenças no desfecho de pacientes com FA admitidos por um AVC recorrente, sendo estratificados de acordo com a etiologia presumida do AVC. Métodos Nós analisamos pacientes com FA admitidos por conta de AVC recorrente em um centro acadêmico terciário de AVC. Os casos de AVC recorrentes foram classificados como "Cardioembólicos", sendo FA sem outros mecanismos alternativos, versus aqueles de etiologia "Indeterminada" por conta de mecanismos concorrentes. Foi usada regressão logística para testar a associação entre a etiologia do AVC recorrente e desfecho favorável (alta direto para casa) após controle para covariáveis importantes. Resultados Nós incluímos 230 pacientes, com uma idade média 76,9 anos (DP ± 11.3), 52.2% homens, com um escore mediano do National Institute of Health Stroke Scale (NIHSS) de 7 (IIQ 2-16). Pacientes com AVC cardioembólicos (65,2%) tiveram um escore de NIHSS mediano mais alto 8,5 (3-18) versus 3 (1-8), e com maior chance de tratamento com terapias de reperfusão. O desfecho favorável ocorreu em 64 pacientes (27,8%) e a mortalidade institucional foi de 15,2% no total. Após ajustes, não encontramos diferença no desfecho entre pacientes com AVC cardioembólico versus AVC de etiologia indeterminada (odds ratio para alta para casa: 1,41; 95% IC: 0,65-3,15). Conclusões Nessa amostra de pacientes com FA e história de AVC recorrente de centro único, não houve diferença no desfecho de alta entre aqueles com AVC cardioembólico e aqueles com etiologia indeterminada. Essa questão deve ser examinada em amostras maiores para melhor compreender a importância do mecanismo do AVC e a profilaxia secundária.

Patrones y resultados del cambio de anticoagulantes orales directos en la fibrilación auricular no valvular: experiencia en la práctica clínica en España / Patterns and outcomes of switching direct oral anticoagulants in non-valvular atrial fibrillation: A real-world experience from Spain

Objetivos El objetivo consistía en evaluar un programa de gestión de anticoagulantes orales directos (ACOD) en pacientes con fibrilación auricular no valvular (FANV) según sus perfiles, idoneidad de la dosis, patrones de cambio de tratamiento, efectividad y seguridad Se trató de un estudio observacional, prospectivo y longitudinal en una cohorte de pacientes atendidos en la práctica clínica cotidiana en un hospital regional español con un plan de seguimiento de 3 años para pacientes que iniciaron el tratamiento con dabigatrán, rivaroxabán o apixabán entre enero de 2012 y diciembre de 2016. Métodos Se analizaron 490 episodios de tratamiento (apixabán 2,5mg, 9,4%; apixabán 5mg, 21,4%; dabigatrán 75mg, 0,6%; dabigatrán 110mg, 12,4%; dabigatrán 150mg, 19,8%; rivaroxabán 15mg, 17,8%; rivaroxabán 20mg, 18,6%) en 445 pacientes. En el 13,6% de los pacientes tratados con dabigatrán, el 9,7% de los tratados con rivaroxabán y el 3,9% de los tratados con apixabán se cambió a otros ACOD o se modificó la dosis. Resultados El ACOD al que se cambió con mayor frecuencia fue el apixabán. Los motivos más frecuentes para cambiar de tratamiento fueron toxicidad (23,8%), hemorragia (21,4%) y deterioro renal (16,7%). En el 23,8% de los episodios se constató una inadecuación de la dosis. Las tasas de ictus y accidentes isquémicos transitorios (AIT) fueron de 1,64 y 0,54 eventos/100 años/paciente, respectivamente, mientras que las de hemorragias importantes, no importantes, pero clínicamente relevantes (NICR) e intracraneales fueron de 2,4, 5 y 0,5 eventos/100 años/paciente, respectivamente. Las hemorragias digestivas y genitourinarias fueron el tipo más frecuente de eventos hemorrágicos. En el análisis multifactorial, el ictus previo y la edad fueron factores predictivos independientes de ictus/AIT. El uso concomitante de antiagregantes plaquetarios, el sexo masculino y la edad fueron factores predictivos independientes de eventos hemorrágicos (AU)

Aims The aim is to evaluate a management program for direct oral anticoagulants (DOACs) in non-valvular atrial fibrillation (NVAF) patients according to their profiles, appropriateness of dosing, patterns of crossover, effectiveness and safety. This is an observational and longitudinal prospective study in a cohort of patients attended in daily clinical practice in a regional hospital in Spain with 3-year a follow-up plan for patients initiating dabigatran, rivaroxaban or apixaban between Jan/2012 and Dec/2016. Methods We analyzed 490 episodes of treatment (apixaban 2.5, 9.4%; apixaban 5, 21.4%; dabigatran 75, 0.6%; dabigatran 110, 12.4%; dabigatran 150, 19.8%; rivaroxaban 15, 17.8% and rivaroxaban 20, 18.6%) in 445 patients. 13.6% of patients on dabigatran, 9.7% on rivaroxaban, and 3.9% on apixaban switched to other DOACs or changed dosing. Results Apixaban was the most frequent DOAC switched to. The most frequent reasons for switching were toxicity (23.8%), bleeding (21.4%) and renal deterioration (16.7%). Inappropriateness of dose was found in 23.8% of episodes. Rates of stroke/transient ischemic attack (TIA) were 1.64/0.54 events/100 patients-years, while rates of major, clinically relevant non-major (CRNM) bleeding and intracranial bleeding were 2.4, 5, and 0.5 events/100 patients-years. Gastrointestinal and genitourinary bleeding were the most common type of bleeding events (BE). On multivariable analysis, prior stroke and age were independent predictors of stroke/TIA. Concurrent platelet inhibitors, male gender and age were independent predictors of BE. Conclusion This study complements the scant data available on the use of DOACs in NVAF patients in Spain, confirming a good safety and effectiveness profil (AU)

Perspectiva neurológica en la elección del anticoagulante oral directo para la prevención del accidente cerebrovascular en fibrilación auricular / Neurological perspective in the choice of direct oral an ticoagulants for prevention of stroke in atrial fibrillation

Resumen La fibrilación auricular no valvular (FA) es la arritmia con potencial embolígeno más prevalente y una de las principales y crecientes causas de accidente cerebrovas cular isquémico (ACVi). El principal objetivo del uso de la anticoagulación en pacientes con FA es la prevención del ACVi. Hasta hace poco tiempo, la anticoagulación con antagonistas de la vitamina K (AVKs) era la única opción disponible. Los anticoagulantes orales directos (DOACs) como el inhibidor directo de la trombina, dabigatrán, o los inhibidores directos del factor Xa, rivaroxabán, apixa bán y edoxabán, tienen un perfil de efectividad/seguridad más favorable en comparación con los AVKs. No existen estudios que comparen la efectividad de los DOACs entre sí. La elección del DOAC depende de múltiples factores específicos del paciente, preferencias del médico, costos y accesibilidad. Entre 1-2% de los pacientes correctamente tratados con un DOAC intercurre con un ACVi cada año. La posibilidad de contar con un agente reversor debería ser tenida en cuenta al momento de la elección del DOAC, especialmente por el riesgo residual de ocurrencia de ACVi. En la actualidad, en nuestro país solo el dabigatrán cuenta con un agente reversor disponible y lo convierte en el único DOAC que no contraindica el uso de trombolisis intraveno sa con rtPA. Esta situación debería ser considerada en el momento de la elección del DOAC para la prevención de eventos tromboembólicos en pacientes con FA.

Abstract Non-valvular atrial fibrillation (AF) is the most preva lent arrhythmia with high embolic potential, and one of the main and growing causes of stroke. The main objec tive of anticoagulation in patients with AF is prevention of stroke. Until recently, anticoagulation with vitamin K antagonists (VKAs) was the only available option. Direct oral anticoagulants (DOACs), such as the direct thrombin inhibitor dabigatran, or the direct factor Xa inhibitors rivaroxaban, apixaban, and edoxaban, have a more favor able effectiveness/safety profile compared to VKAs. There are no studies comparing the efficacy of DOACs with each other. The choice of a DOAC arose from patient car achterictis, physician preferences, cost, and accessibility. Between 1-2% of patients correctly treated with a DOAC experience a stroke each year. The possibility of having a reversal agent should be taken into account when choos ing a DOAC, especially due to the residual risk of stroke occurrences even under DOACs. Currently, in our country only dabigatran has a reversing agent available, making it the only DOAC that does not contraindicate the use of intravenous thrombolysis. This should be taken into account when choosing the DOAC for the prevention of thromboembolic events in patients with AF.

[Direct-acting oral anticoagulants in antiphospholipid syndrome: A systematic review]. / Anticoagulantes de acción directa en el síndrome antifosfolípido. Revisión sistemática.

The objective of the systematic review is to analyze the efficacy of direct-acting oral anticoagulants (DOAC) in the prophylaxis of thrombosis in antiphospholipid syndrome (APS). We searched for clinical trials, cohort studies and meta-analyses published from January 1, 2012 to September 30, 2022. Articles that analyzed the efficacy of DOAC in the prevention of thrombosis recurrence, with or without comparison with antivitamin K (VKA) drugs, were selected. DOACs, specifically rivaroxaban and apixaban, were significantly less effective than VKAs in preventing recurrence of thrombosis in patients with APS and prior arterial thrombosis or the concomitant presence of two or three different antiphospholipid antibodies. The proportion of patients with severe bleeding as side effect are similar in those treated with DOAC and with VKA. The results argue against the use of DOAC in the treatment of patients with thrombotic APS.

Spontaneous pulmonary hematoma in patients with COVID-19.

The disease caused by Sars-Cov-2 (Covid-19) has become a worldwide pandemic and consequently a public health problem. Multiple complications associated with Covid-19 have been described, including coagulation abnormalities. Although the infection is known to induce a prothrombotic state, hemorrhagic complications have also been reported in patients with Covid-19, especially in anticoagulated patients. We present two cases of spontaneous pulmonary hematoma in patients with Covid-19 undergoing anticoagulant treatment. We aim to describe this complication, which although uncommon, should be taken into account in anticoagulated patients with Covid-19.

Anticoagulación en enfermedad renal crónica G4-5 en una red de hospitales de Bogotá

Contexto: la anticoagulación en pacientes con enfermedad renal crónica es un reto terapéutico debido a que la evidencia médica es escasa y los beneficios son discutibles, además, el riesgo de sangrado en estos pacientes es mayor. Objetivo: describir los pacientes con enfermedad renal G4-5 que recibieron terapia anticoagulante oral durante por lo menos tres meses en la Subred Centro Oriente de Bogotá. Metodología: estudio analítico de pacientes con enfermedad renal crónica G4-5 en un hospital de referencia entre enero del 2018 y diciembre del 2021, en el cual se analizaron variables sociodemográficas, clínicas y se realizó una regresión logística sobre los anticoagulantes y la frecuencia de eventos (hemorrágicos o embólicos). Resultados: se evaluó a 75 pacientes con diagnóstico de enfermedad renal crónica G4-5 anticoagulados, donde el anticoagulante más usado fue warfarina (76 %), seguido de apixabán (16 %) y rivaroxabán (8 %). El sangrado mayor se presentó con warfarina (8,47 %), apixabán (10%) y rivaroxabán (16,6 %). No se encontraron diferencias significativas entre el sangrado mayor con warfarina (OR: 2,8; IC 95 %: 0,46-16,9; p = 0,262) y rivaroxabán (OR: 1,86; IC 95 %: 0,18-18,7; p = 0,596), además, el sangrado no mayor y clínicamente relevante fue del 28,9 % con warfarina. Solo se presentó una complicación trombótica en un paciente que recibió rivaroxabán. Conclusiones: en los pacientes con enfermedad renal G4-5 que recibieron warfarina y los anticoagulantes orales directos no se encontraron diferencias significativas en cuanto a la presentación de sangrado mayor y no mayor, clínicamente relevantes.

Background: Anticoagulation in patients with chronic kidney disease is a therapeutic challenge since the medical evidence is scarce and the benefits are debatable since the risk of bleeding in these patients is greater. Purpose: To describe patients with G4-5 kidney disease who received oral anticoagulant therapy for at least 3 months in the central-eastern subnetwork of Bogotá. Methodology: Analytical study of patients with G4-5 chronic kidney disease, in a reference hospital between January 2018 and December 2021, in which sociodemographic and clinical variables were analyzed, and a logistic regression was performed on anticoagulants and the frequency of events (hemorrhagic or embolic). Results: 75 anticoagulated patients diagnosed with G4-5 chronic kidney disease were evaluated. The most commonly used anticoagulant was warfarin (76%), apixaban (16%), and rivaroxaban (8%). Major bleeding occurred with warfarin (8.47%), apixaban (10%), and rivaroxaban (16.6%). There are no significant differences between major bleeding with warfarin (OR: 2.8; 95% CI: 0.46;16.9; p= 0.262), and rivaroxaban (OR: 1.86; 95% CI: 0.18;18.7; p=0.596). Clinically relevant non-major bleeding was 28.9% with warfarin. A thrombotic complication only occurred in one patient who received rivaroxaban. Conclusions: In patients with G4-5 kidney disease who received warfarin and direct oral anticoagulants, no significant differences were found in terms of the presentation of clinically relevant major and non-major bleeding.

Describing the Oral Health of Warfarin Users. A Short Report

Aim: To describe the burden of oral diseases and of self-reported periodontal disease of patients under Oral Anticoagulation Therapy (OAT) with warfarin. Methods: A cross-sectional study was conducted. Validated questionnaires assessed self-reported periodontal disease and demographic variables. After calibration (Kappa > 0.80), an examiner evaluated dental caries and the need for dental prostheses. Statistical analysis involved proportions and measures of central tendency. Results: The sample consisted of 158 individuals, with a mean age of 58.8 years (SD = 12.1), of which 62.7% of the participants were women. The average DMFT (Decayed, Missing, and Filled Teeth) index was 22.9 (SD = 7.6), with the missing component being the highest (Mean = 16.23). The use of maxillary prosthesis (53.2%) was higher than mandibular (32.3%). The need for mandibular prosthesis reached 66.5%. The percentage of participants that referred gum disease, tooth migration, and tooth mobility was 29.6%, 37.4%, and 30.4%, respectively. Conclusions: The burden of oral diseases among individuals undergoing OAT is worrisome.

Objetivo: Describir la carga de enfermedades bucales y la enfermedad periodontal autorreportada de pacientes en tratamiento con anticoagulación oral con warfarina. Métodos: Se realizó un estudio transversal. Los cuestionarios validados evaluaron la enfermedad periodontal autoinformada y las variables demográficas. Después de la calibración (Kappa> 0.80), un examinador evaluó la caries dental y la necesidad de prótesis dentales. El análisis estadístico involucró proporciones y medidas de tendencia central. Resultados: La muestra estuvo formada por 158 individuos, con una edad media de 58.8 años (DE = 12.1), de los cuales el 62.7% de los participantes eran mujeres. El índice CPOD promedio fue de 22.9 (DE = 7.6), siendo el componente perdido el que más contribuyó al índice (Media = 16.23). El uso de prótesis maxilar (53.2%) fue mayor que el de prótesis mandibular (32.3%). La necesidad de prótesis mandibular alcanzó el 66.5%. El porcentaje de participantes que informaron enfermedad de las encías, migración de los dientes y movilidad de los dientes fue del 29.6%, 37.4% y 30.4%, respectivamente. Conclusiones: Las enfermedades bucales y la necesidad de rehabilitación oral entre los individuos sometidos a anticoagulación oral con warfarina fue motivo de preocupación.

Hematoma pulmonar espontáneo en pacientes con COVID-19 / Spontaneous pulmonary hematoma in patients with COVID-19

La enfermedad causada por SARS-CoV-2 (Covid-19) se ha convertido en una pandemia mundial y en consecuencia en un problema de salud pública. Se han descrito múltiples complicaciones asociadas a la COVID-19, entre ellas alteraciones de la coagulación. Si bien es conocido que la infección induce un estado protrombótico, también se han descrito complicaciones hemorrágicas en estos pacientes, sobre todo en pacientes anticoagulados. Presentamos dos casos de hematoma pulmonar espontáneo en pacientes con neumonía COVID-19 y terapia anticoagulante. Nuestro objetivo es describir esta complicación, que, aunque poco frecuente, conviene tener en cuenta en pacientes anticoagulados y con COVID-19 concomitante (AU)
