Hemorrhagic Versus Ischemic Risk in Patients with Atrial Fibrillation on Hemodialysis

Abstract Background Hemodialysis (HD) patients with atrial fibrillation (AF) have a particularly high risk of stroke and bleeding, but no high-quality evidence-based recommendations exist to properly manage these patients. Objectives We aim to evaluate the ischemic versus the hemorrhagic risk in a HD population with AF. Methods We selected incident patients that started hemodialysis between 2011 and 2015. All patients that had AF before HD, or developed AF during the follow-up, were included. Both CHA2DS2 -VASC and HAS-BLED scores were calculated at the time of beginning of HD or AF diagnosis and correlated with the outcomes using a logistic regression model. The outcomes were hemorrhagic events, ischemic events and death related to any of these events. A p-value < 0.05 was set as statistically significant. Results Forty-six patients were included. Most of them had had AF before they started hemodialysis. Twenty-two patients were on oral anticoagulation (OAC). There was no significant difference between the incidence of ischemic and hemorrhagic events, regardless of the use of OAC. Previous stroke, transient ischemic attack, and thromboembolic event significantly increased the risk of an ischemic event (OR 6.78, p=0.028). Conclusions In this population, we did not observe any difference between the incidence of ischemic and hemorrhagic events, which was also true in patients with OAC. Therefore, the benefit of OAC in such patients remains questionable. However, patients with previous stroke, transient ischemic attack, or thromboembolic event seem to have a higher risk of new ischemic events and might benefit from anticoagulation.

Risk of Bleeding after Transcatheter Aortic Valve Replacement: impact of Preoperative Antithrombotic Regimens

Abstract Introduction: Bleeding after transcatheter aortic valve replacement (TAVR) has a negative impact on the outcome of the procedure. Risk factors for bleeding vary widely in the literature, and the impact of preoperative antithrombotic agents has not been fully established. The objectives of our study were to assess bleeding after TAVR as defined by the Valve Academic Research Consortium-2 (VARC-2), identify its risk factors, and correlate with antithrombotic treatment in addition to its effect on procedural mortality. Methods: The study included 374 patients who underwent TAVR from 2009 to 2018. We grouped the patients into four groups according to the VARC-2 definition of bleeding. Group 1 included patients without bleeding (n=265), group 2 with minor bleeding (n=22), group 3 with major bleeding (n=61), and group 4 with life-threatening bleeding (n=26). The median age was 78 (25th-75th percentiles: 71-82), and 226 (60.4%) were male. The median EuroSCORE was 3.4 (2-6.3), and there was no difference among groups (P=0.886). The TAVR approach was transfemoral (90.9%), transapical (5.6%), and trans-subclavian (1.9%). Results: Predictors of bleeding were stroke (OR: 2.465; P=0.024) and kidney failure (OR: 2.060; P=0.046). Preoperative single and dual antiplatelet therapy did not increase the risk of bleeding (P=0.163 and 0.1, respectively). Thirty-day mortality occurred in 14 patients (3.7%), and was significantly higher in patients with life-threatening bleeding (n=8 [30.8%]; P<0.001). Conclusion: Bleeding after TAVR is common and can be predicted based on preprocedural comorbidities. Preprocedural antithrombotic therapy did not affect bleeding after TAVR in our population.

Advancing in the understanding of coagulopathy during hemorrhagic shock: From the triad to the deadly pentad / Avanzando en el entendimiento de la coagulopatía durante el choque hemorrágico: de la tríada a la pentada mortal

Abstract The deadly triad concept represented a dogma in the definition of poor outcomes and death associated with major bleeding in trauma. This model of end-stage disease was then rapidly transferred to other major bleeding scenarios. However, and notwithstanding the fact that it represented a severe scenario, the original triad fails to establish a sequence, which would be relevant when defining the objectives during the initial treatment of severe bleeding. Likewise, this model admits only one scenario where all the conditions shall co-exist, knowing that each one of them contributes with a different risk burden. Based on a structured review, we propose a pentad model that includes a natural pattern of events occurring with hypoxemia as the main trigger for the development of hypocalcemia, hyperglycemia, acidosis and hypothermia, as surrogates of multi-organ impairment. This severity model of major bleeding considers coagulopathy as a result of the failure to restore the initial components of damage.

Resumen El concepto de la tríada mortal significó un dogma en la definición de malos desenlaces y muerte asociados al sangrado mayor en trauma. Este modelo de afectación terminal fue luego rápidamente trasladado a otros escenarios de sangrado mayor. Sin embargo y a pesar de significar un escenario de gravedad, la tríada original falla en adjudicar una secuencialidad, lo cual sería importante a la hora de definir los objetivos durante el tratamiento inicial de la hemorragia grave. De igual forma, solo admite un único escenario en donde deben coexistir todas las condiciones, cuando se sabe que cada una atribuye una carga diferencial de riesgo. A partir de una revisión estructurada proponemos un modelo de pentada que incluye un patrón natural de eventos que se implantan sobre la hipoxemia como principal detonante para el desarrollo de hipocalcemia, hiperglucemia, acidosis e hipotermia como representantes del deterioro en múltiples sistemas. Este modelo de gravedad del sangrado mayor culmina con la coagulopatía como resultante de la falla en la resolución de los demás componentes previos.

Resumen Introducción: Los medicamentos antiulcerosos son utilizados frecuentemente en pacientes hospitalizados, sin embargo, a menudo este uso no está indicado. Objetivo: Describir la frecuencia de prescripción e indicación de medicamentos para prevenir el sangrado gastrointestinal en pacientes hospitalizados. Materiales y métodos: Estudio de corte trasversal, descriptivo, prospectivo del servicio de Medicina Interna de la Sociedad de Cirugía de Bogotá- Hospital de San José de Bogotá, Colombia. Se excluyeron pacientes con diagnóstico de sangrado gastrointestinal o antecedente de alergia a los medicamentos antiulcerosos. Se recolectaron datos demográficos, así como fármacos prescritos. Se determinó si la indicación del fármaco era adecuada y se identificó el tipo de error de prescripción. Resultados: Se incluyeron 179 pacientes, 102 (57%) mujeres. Promedio de edad de 61,3 años (±20,2). El principal diagnóstico de ingreso fue enfermedad infecciosa 76 (42,4%). Del total de pacientes, 165 (92,17%) recibieron medicamento para prevención del sangrado gastrointestinal. La indicación fue adecuada en 75 pacientes (41,89%). El error más frecuente fue el uso en pacientes de bajo riesgo de sangrado, 101 (97,1%). Conclusión: Un alto porcentaje de los pacientes recibió medicación para la prevención del sangrado gastrointestinal. En aproximadamente la mitad de estos no estaba indicada.

Abstract Introduction: Anti-ulcer medications are frequently used in hospitalized patients, yet their use is not usually indicated. Objective: To describe the frequency of prescription and indication of medications to prevent gastrointestinal bleeding in hospitalized patients. Materials and methods: A cross-sectional, descriptive, prospective study was carried out in the Internal Medicine service of the Surgery Society of Bogota-San Jose Hospital of Bogota (Colombia). Excluded patients were those with either a gastrointestinal bleeding diagnosis or a history of allergy to anti-ulcer medications. Demographic data and information regarding prescribed medications were collected. It was determined whether the medicine indication was adequate and the type of prescription error was identified. Results: 179 patients were included in the study, 57% (102) of which were women. The average age was 61.3 (±20.2) years old. Infectious disease was the main admission diagnosis (76; 42.4%). A 92.17% (165) of the total number of patients received medications to prevent gastrointestinal bleeding. This indication was adequate for 75 (41.89%) patients. The most frequent error was their use in bleeding low-risk patients (101; 97.1%). Conclusion: A high percentage of patients received medication to prevent gastrointestinal bleeding. However, in about half of these patients it was not indicated.

Resumen El accidente cerebrovascular (ACV) constituye la principal causa de discapacidad de origen neuro- lógico en los adultos mayores a 40 años y la cuarta causa de muerte en Argentina. En los últimos diez años las publicaciones indexadas relacionadas al tratamiento del ACV isquémico fueron más numerosas que las de ACV hemorrágico. El objetivo de este material es proporcionar recomendaciones locales y actualiza- das del abordaje de pacientes con hematoma intraparenquimatoso espontáneo durante la internación. Para la redacción de este manuscrito se convocó a especialistas en esta enfermedad que conformaron grupos de trabajo. Se plantearon 10 tópicos centrales expresados como epidemiologia, atención inicial, imágenes, tratamiento de la presión arterial, reversión de antitrombóticos, indicación de cirugía, profilaxis anticonvulsivante, pronóstico, prevención de complicaciones y reinicio de antitrombóticos. De cada tópico se plantearon mediante preguntas PICO los interrogantes más frecuentes de la práctica diaria. Luego de una revisión sistemática de la literatura, se generaron recomendaciones evaluadas mediante sistema GRADE y consensuadas entre autores y pacientes.

Abstract Stroke is the leading cause of neurological disability in people over 40 years of age and the fourth leading cause of death in Argentina. In the last ten years, the indexed publications related to the treatment of ischemic stroke were more numerous than those of hemorrhagic stroke. The objective of this material is to provide local and updated recommendations for the management of patients with spontaneous intracere- bral hemorrhage during hospitalization. For the writing of this manuscript, diferent specialists were convened to form working groups. Ten central topics expressed as epidemiology, initial care, imaging, blood pressure treatment, reversal of antithrombotics, indication for surgery, seizure prophylaxis, prognosis, prevention of complications and resumption of antithrombotics were raised. For each topic, the most frequent questions of daily practice were raised through PICO questions. After a systematic review of the literature, recommendations were generated, evaluated using the GRADE system and agreed between authors and patients.

Effect of patellar resurfacing surgery on bleeding in total knee arthroplasty

SUMMARY OBJECTIVE: Postoperative bleeding is one of the most important factors affecting clinical and functional results in total knee arthroplasty. Therefore, many studies have been conducted on bleeding in arthroplasty patients. However, there are very few reports investigating the effect of patellar surface replacement on bleeding in knee arthroplasty. We, therefore, aimed to investigate the effect of patellar surface replacement on postoperative bleeding. METHODS: In this retrospective study, 30 with patellar resurfacing were compared with 39 without patellar resurfacing among patients who had undergone total knee replacement due to primary osteoarthritis. Demographic data, amount of transfusion, preoperative and postoperative hemoglobin and hematocrit values, and total, visible, and hidden blood loss values were recorded. RESULTS: No statistical difference was found between the two groups in terms of demographic values. There was no significant difference between the groups in terms of the amount of blood in the drain, total blood loss, hidden blood loss, and blood transfusion in patients who had and had not undergone patellar resurfacing. A positive significant correlation was found between postoperative drainage volume and total blood loss. CONCLUSION: Patellar component application in patients who had undergone total knee arthroplasty does not change the blood loss of the patients.

Este experimento usando anestesia bloques general y local de los nervios de la córnea y alrededor de la base del cuerno con naylon pinza de sutura de la piel, asociados con la ligadura de la vena y la arteria cornual fue eficiente que reduce el tiempo quirúrgico el campo y la promoción de una prevención temprana sangrado que es común para este procedimiento.(AU)

Qualidade da Anticoagulação Oral em Pacientes com Fibrilação Atrial em um Hospital Terciário no Brasil / Quality of Oral Anticoagulation in Atrial Fibrillation Patients at a Tertiary Hospital in Brazil

Resumo Fundamento A fibrilação atrial (FA) afeta de 0,5% a 2,0% da população geral e geralmente está associada a doenças estruturais cardíacas, comprometimento hemodinâmico e complicações tromboembólicas. A anticoagulação oral previne eventos tromboembólicos e é monitorada pela razão normalizada internacional (RNI). Objetivos Avaliar a estabilidade do RNI em pacientes com FA não valvar tratados com anticoagulante varfarina, avaliar complicações tromboembólicas ou hemorrágicas e identificar o grupo com risco mais alto de eventos tromboembólicos ou hemorrágicos. Métodos Dados de prontuários médicos de 203 pacientes atendidos em um hospital terciário no Brasil foram analisados e o tempo de intervalo terapêutico (TTR) foi calculado usando-se o método Rosendaal. Em seguida possíveis fatores que influenciam o TTR foram analisados e a relação entre TTR e eventos tromboembólicos ou hemorrágicos foi calculada. O nível de significância foi 5%. Resultados O TTR médio foi 52,2%. Pacientes com instabilidade de RNI na fase de adaptação tinham um TTR médio mais baixo (46,8%) do que aqueles sem instabilidade (53,9%). Entre os pacientes estudados, 6,9% sofreram eventos hemorrágicos e 8,4% tiveram um acidente vascular cerebral. O grupo com risco mais alto de acidente vascular cerebral e sangramento era composto de pacientes com instabilidade de RNI na fase de adaptação. Conclusões A qualidade da anticoagulação nesse hospital terciário no Brasil é semelhante à de centros de países em desenvolvimento. Pacientes com instabilidade de RNI maior na fase de adaptação evoluíram para um TTR médio mais baixo durante o acompanhamento, tinham uma chance de acidente vascular cerebral 4,94 vezes maior e uma chance de sangramento 3,35 vezes maior. Portanto, para esse grupo de pacientes, individualizar a escolha de tratamento anticoagulante seria recomendado, considerando-se a relação custo-benefício.

Abstract Background Atrial fibrillation (AF) affects 0.5% to 2.0% of the general population and is usually associated with cardiac structural diseases, hemodynamic damage, and thromboembolic complications. Oral anticoagulation prevents thromboembolic events and is monitored by the international normalized ratio (INR). Objectives To evaluate INR stability in nonvalvular AF patients treated with warfarin anticoagulation, to evaluate thromboembolic or hemorrhagic complications, and to identify the group at higher risk for thromboembolic or hemorrhagic events. Methods Data from the medical records of 203 patients who received medical care at a tertiary hospital in Brazil were reviewed, and the time in therapeutic range (TTR) was calculated using the Rosendaal method. The possible TTR influencing factors were then analyzed, and the relationship between the TTR and thromboembolic or hemorrhagic events was calculated. The level of significance was 5%. Results The mean TTR was 52.2%. Patients with INR instability in the adaptation phase had a lower mean TTR (46.8%) than those without instability (53.9%). Among the studied patients, 6.9% suffered hemorrhagic events, and 8.4% had a stroke. The higher risk group for stroke and bleeding consisted of patients with INR instability in the adaptation phase. Conclusions The quality of anticoagulation in this tertiary hospital in Brazil is similar to that in centers in developing countries. Patients with greater INR instability in the adaptation phase evolved to a lower mean TTR during follow-up, had a 4.94-fold greater chance of stroke, and had a 3.35-fold greater chance of bleeding. Thus, for this patient group, individualizing the choice of anticoagulation therapy would be advised, considering the cost-benefit ratio.

Cola de cianoacrilato para varizes gastroesofágicas: uma única experiência central no norte da Índia / Cyanoacrylate glue for gastroesophageal varices: a single centre experience from north india

ABSTRACT Background: In natural history of cirrhosis, variceal bleeding is one of the earliest decompensations to happen, and, if adequately managed, survival is improved. Gastric varices have challenges in management due to their location, size and propensity to bleed. The N-butyl 2-cyanoacrylate (NBC) glue application has emerged as definitive therapy in bleeding gastric varices. Here we present our experience with use of NBC in management of gastric and difficult cases of esophageal varices. Methods: A total of 75 patients underwent NBC glue application for varices which included 69 patients with gastric varices and six patients with esophageal varices. All the procedures were done with flexible endoscope and sclerotherapy needle after due precautionary measures. Results: Hemostasis was varices in all patients after endotherapy. The average quantity of glue used was 2.75±0.95 mL. Complete obliteration with single session of NBC application was achieved in 55 patients. Re-bleeding occurred in five patients within 5 days of index event. 20 patients had in-hospital mortality but none was related to gastrointestinal bleeding. 6-week all-cause mortality was 26 (35%). Conclusion: Glue therapy with NBC is a life saving therapy in patients with bleeding gastric varices and esophageal varices not amenable to endoscopic variceal ligation or sclerotherapy.

RESUMO Contexto: Na história natural da cirrose, o sangramento de varizes é uma das primeiras descompensações a acontecer e, se adequadamente controlada, a sobrevivência é melhorada. Varizes gástricas têm desafios na sua gestão devido à sua localização, tamanho e propensão a sangrar. A aplicação de cola N butil 2-cianoacrilato (NBC) surgiu como terapia definitiva em varizes gástricas sangrantes. Apresentamos nossa experiência com o uso da NBC na gestão de casos gástricos e difíceis de varizes esofágicas. Métodos: Um total de 75 pacientes foram submetidos à aplicação de cola NBC para varizes que incluiu 69 pacientes com varizes gástricas e seis pacientes com varizes de esôfago. Todos os procedimentos foram feitos com endoscópio flexível e agulha de escleroterapia após as devidas medidas de precaução. Resultados: A hemostasia foi alcançada em todos os pacientes após a endoterapia. A quantidade média de cola utilizada foi de 2,75+0,95 mL. A obliteração completa com sessão única de aplicação da NBC foi alcançada em 55 pacientes. O reexame ocorreu em cinco pacientes dentro de 5 dias após o evento de índice. 20 pacientes tiveram mortalidade hospitalar, mas nenhum foi relacionado com o sangramento gastrointestinal. A mortalidade após 6 semanas foi de 26 (35%). Conclusão: A terapia de cola com a NBC é uma terapia que salva vidas em pacientes com varizes gástricas hemorrágicas e varizes esofágicas não condizíveis à ligadura endoscópica ou escleroterapia.

Pacientes com HSA aneurismática sobreviventes apresentaram menores idades, escore SAPS III, escalas neurológicas e tempo de VM, maiores escores de ECG, na admissão e na alta da UTI e maior tempo de internação hospitalar que os não sobreviventes. Os pacientes sobreviventes apresentaram melhor funcionalidade que os não sobreviventes na admissão, e, evoluíram com melhora funcional da admissão até a alta da UTI.

Introduction. Rehabilitation has recently been discussed in patients with subarachnoid hemorrhage (SAH) caused by a ruptured aneurysm. Objective. To compare clinical and functional outcomes of surviving and non-surviving patients with aneurysmal SAH in a neurosurgical ICU. Methods. This is a retrospective documentary study. Medical records of patients with SAH admitted to the neurosurgical ICU of a teaching hospital between July 2014 and July 2019 were analyzed. Data were divided according to the outcomes into survivors group (SG) and non-survivors group (NG). Results. 103 patients were analyzed, 72% female, mean age 55 years, 62% had high ICU outcome. The SG had significantly lower age, SAPS III score, Fisher and Hunt-Hess scales and time on mechanical ventilation (MV) than the NG, in addition, they had a Glasgow Coma Scale (GCS), on admission and discharge from the ICU and length of hospital stay, significantly higher (p≤0.05) than NG. The SG showed significantly higher functionality (p≤0.05) than the NG on admission and a significant increase (p≤0.05) in functionality between admission and discharge from the ICU. Conclusion. Surviving patients with aneurysmal SAH had lower age, SAPS III score, neurological scales and time on MV, higher GCS scores at ICU admission and discharge, and longer hospital stay than non-survivors. Surviving patients had better functionality than non-survivors on admission, and, evolved with functional improvement from admission to discharge from the ICU.

Complicaciones ORL severas por mononucleosis infecciosa en adolescentes sanos: 2 casos clínicos y revisión de la literatura / ENT severe complications of infectious mononucleosis in healthy adolescents: report of two cases and literature review

Resumen La mononucleosis infecciosa (MI) es un cuadro clínico generalmente benigno y autolimitado en la infancia y adolescencia debido a la primoinfección del virus de Epstein-Barr caracterizado por la triada de faringitis, fiebre y adenopatías. El riesgo de complicaciones aumenta con la edad y la inmunosupresión, siendo las complicaciones letales más frecuentes las asociadas a rotura esplénica, alteraciones neurológicas y obstrucción de la vía aérea por el aumento del tamaño amigdalar. Los abscesos cervicales asociados a MI son poco frecuentes, siendo mayoritariamente periamigdalinos e intraamigdalares. Presentamos dos casos quirúrgicos de abscesos cervicales profundos de gran tamaño con afectación retrofaríngea y parafaríngea en adolescentes sanos de corta edad (14 y 15 años), sin ningún tipo de inmunosupresión o factores de riesgo, uno de ellos asociado además, a una relevante hemorragia amigdalar espontanea, condición no descrita previamente en la literatura en relación a MI en un paciente tan joven.

Abstract Infectious mononucleosis (MI) is a generally benign and self-limited condition in childhood and adolescence due to the primary EBV infection characterized by the triad of pharyngitis, fever, and lymphadenopathies. The risk of complications increases with age and immunosuppression. The most frequent fatal complications are those associated with splenic rupture, neurological alterations, and airway obstruction due to increased tonsillar size. Cervical abscesses associated with MI are rare, being mostly peritonsillar and intra-tonsil. We present two surgical cases of big deep cervical abscesses with retropharyngeal and parapharyngeal involvement in healthy very young adolescents (14 and 15 years old), without any type of immunosuppression or risk factors, one of them associated with a clinically relevant spontaneous tonsillar bleeding, which had not been described in the literature associated with MI in such young patient.

Manejo de hemorragia posamigdalectomía en Chile / Treatment of post tonsillectomy bleeding in Chile

Resumen Introducción: La amigdalectomía es una de las cirugías más frecuentes en la población pediátrica. Aunque se considera una cirugía sencilla y segura, no está exenta de riesgos, siendo el principal la hemorragia posoperatoria. Objetivo: Evaluar el manejo de la hemorragia posamigdalectomía en otorrinolaringólogos en Chile. Material y Método: Se realizó un estudio transversal descriptivo sobre la experiencia y manejo de hemorragias posamigdalectomía mediante una encuesta difundida a socios activos de la Sociedad Chilena de Otorrinolaringología, Medicina y Cirugía de Cabeza y Cuello (SOCHIORL). Resultados: Se recopilaron respuestas de 102 de los 348 socios. El 97% ha presentado esta complicación. La medida inicial ante una hemorragia tardía fuera de una unidad de otorrinolaringología es derivar al servicio de urgencias en el 88% de los casos. En urgencia, la indicación más frecuente es administrar ácido tranexámico endovenoso en un 80%. En el caso de hemorragia sin estigmas de sangrado actual, un 68% indica alta con control precoz. Si se evidencian coágulos en la fosa amigdalina, el 72% indica hospitalización para observación. Si se evidencia sangrado activo, el 94% indica hospitalización y revisión de hemostasia en pabellón. Conclusión: Los resultados a nivel nacional, según este estudio, son concordantes con la literatura mundial. El manejo en el servicio de urgencia se basa en la experiencia del tratante. Respecto a los distintos escenarios clínicos, se recomienda hospitalización en caso de evidenciar coágulos y manejo en pabellón en la presencia de sangrado activo. El manejo es variable en pacientes sin hallazgos al examen físico.

Abstract Introduction: Tonsillectomy is one of the most frequent surgeries in the pediatric population. Although it is considered a simple and safe surgery, it has associated risks, the main one being postoperative bleeding. Aim: Evaluate the management of post-tonsillectomy hemorrhage in otorhinolaryngologists practicing in Chile. Material and Method: A descriptive cross-sectional study was carried out on the experience and management of post-tonsillectomy hemorrhage through a survey distributed to active members of the Sociedad Chilena de Otorrinolaringología, Medicina y Cirugía de Cabeza y Cuello (SOCHIORL). Results: Responses were collected from 102 out of 348 active members, of which 97% have presented this complication. The initial measure in a late hemorrhage occurring outside of an otolaryngology unit is referral to the emergency department in 88% of cases. In the emergency room, the most frequent management is to administer intravenous tranexamic acid in 80%. In the case of hemorrhage without trace of current bleeding, 68% discharge with early control. If clots are evident in the tonsillar fossa, 72% admit for observation. If there is evidence of active bleeding, 94% admit and perform revision surgery. Conclusion: Results of this study are consistent with international literature. Management in the emergency department is based on the experience of the treating physician and different clinical scenarios. Hospitalization is recommended when clots are observed, revision surgery when evidence of active bleeding and, in patients with no findings at the moment of the evaluation, management is variable.

Evaluación del Orbit Bleeding Risk Score como predictor de sangrado mayor en pacientes con síndrome coronario agudo / Evaluation of the Orbit Bleeding Risk Score as Predictor of Major Bleeding in Patients with Acute Coronary Syndrome

RESUMEN Introducción: El sangrado mayor es la complicación más importante del tratamiento antitrombótico en el síndrome coronario agudo (SCA), y se asocia a mayor mortalidad. Evaluar el riesgo de sangrado es un desafío. La utilidad del Orbit Bleeding score (ORBIT) para evaluar el riesgo de sangrado en SCA ha sido poco estudiada. Objetivo: Evaluar al ORBIT como predictor de sangrado mayor en pacientes internados por SCA en los que se decide la anticoagulación como parte de la estrategia antitrombótica. Materiales y métodos: Se incluyeron en forma retrospectiva pacientes internados en dos unidades coronarias con diagnóstico de SCA que recibieron anticoagulación como parte de la terapia antitrombótica. A todos se les calcularon los scores CRUSADE, ACTION-GWTG y ORBIT con los datos clínicos del ingreso. Se analizo el punto primario de sangrado mayor, definido como una clasificación de BARC 3 o 5. Resultados: Se incluyeron 762 pacientes. El sangrado mayor se presentó en el 3.4%. En el análisis univariado los tres scores fueron predictores de sangrado mayor, mientras que en el multivariado sólo el ORBIT fue predictor independiente de sangrado mayor, con OR 2,46, IC95% 1,61-3,97, p <0,001. El área bajo la curva ROC fue de 0,70, 0,68 y 0,80 para los scores ACTIONGWTG, CRUSADE y ORBIT, respectivamente. El ORBIT presento una mayor área bajo la curva que el CRUSADE (p = 0,03) sin diferencias significativas con el ACTION-GWTG (p = 0,06) Conclusiones: El ORBIT fue el único predictor independiente de sangrado mayor, con una mejor capacidad de discriminación que el CRUSADE, y tendencia a mejor capacidad que el ACTION-GWTG.

ABSTRACT Background: Major bleeding is the most important complication of antithrombotic treatment in acute coronary syndrome (ACS) and is associated with higher mortality. Assessing the risk of bleeding is a challenge. The usefulness of the Orbit Bleeding Score (ORBIT) to assess the risk of bleeding in ACS has been scarcely studied. Objective: The aim of this study was to evaluate the ORBIT score as a predictor of major bleeding in patients hospitalized for ACS in whom anticoagulation is decided as part of the antithrombotic strategy. Methods: Patients admitted to two coronary care units with diagnosis of ACS who received anticoagulation as part of the antithrombotic therapy were retrospectively included in the study. The CRUSADE, ACTION-GWTG and ORBIT scores were calculated using the admission clinical data. The primary endpoint was major bleeding, defined as BARC 3 or 5 classification. Results: The study included 762 patients. Major bleeding occurred in 3.4% of cases. In the univariate analysis, the three scores were predictors of major bleeding, while in the multivariate analysis only the ORBIT score was an independent predictor of major bleeding (OR: 2.46, 95% CI 1.61-3.97, p <0.001). The area under the ROC curve was 0.70, 0.68 and 0.80 for the ACTION-GWTG, CRUSADE and ORBIT scores, respectively. The ORBIT score presented a higher area under the curve than the CRUSADE score (p=0.03) but without significant difference with the ACTION-GWTG score (p=0.06) Conclusions: The ORBIT score was the only independent predictor of major bleeding, presenting a better discrimination capacity than the CRUSADE score and a tendency to better capacity than the ACTION-GWTG score.

El dilema de la anticoagulación en pacientes con fibrilación auricular y enfermedad renal crónica de grado 5 / The dilemma of anticoagulation in patients with atrial fibrillation and stage 5 chronic kidney disease

Resumen No hay evidencia sólida acerca de la eficacia y la seguridad de la anticoagulación en pacientes con fibrilación auricular no valvular y enfermedad renal crónica de grado 5, porque esta población ha sido excluida de los grandes ensayos clínicos controlados. La decisión de anticoagular en este escenario ha estado supeditada a los resultados de estudios observacionales con warfarina, algunos reportando un aumento en la incidencia de sangrado y ataque cerebrovascular con la anticoagulación, y a los de una cohorte retrospectiva con apixabán que encontró una reducción significativa del riesgo de sangrado mayor comparado con warfarina, y en el subgrupo de pacientes con dosis estándar de apixabán, además, una disminución del riesgo de ataque cerebrovascular. Evidencia reciente sugiere que, en pacientes con fibrilación auricular en hemodiálisis, la anticoagulación con apixabán no reduce los eventos cerebrovasculares, pero sí se asocia con mayor incidencia de sangrado en comparación con la no anticoagulación. En este artículo se hace una revisión narrativa de la literatura y se propone un algoritmo para el abordaje del paciente con fibrilación auricular no valvular y enfermedad renal crónica de grado 5.

Abstract Currently, there is no solid evidence regarding safety and efficacy of anticoagulation therapy in patients with non-valvular atrial fibrillation and stage 5 chronic kidney disease, as this population has been excluded from randomized controlled clinical trials. The decision to start anticoagulation in such setting has been based in results of observational studies with warfarin, some reporting an increase incidence of both bleeding and stroke, and with apixaban which was associated with a significant reduction in bleeding, stroke and death risk, compared to warfarin. Recent evidence suggests that, in patients with atrial fibrillation on hemodialysis, anticoagulation with apixaban does not reduce the incidence of stroke, but it is associated with a higher bleeding rate compared to no therapy at all. A narrative review of the literature was performed and a therapeutic approach is proposed for anticoagulation in patients with non-valvular atrial fibrillation and stage 5 chronic kidney disease.
