RESUMO

Objetivos: Analizar los factores relacionados con el uso de digoxina en urgencias en pacientes con insuficiencia cardiaca aguda (ICA) y el impacto pronóstico a corto plazo. Método: Se incluyeron pacientes diagnosticados de ICA en 45 servicios de urgencias españoles sin tratamiento crónico con digoxina, los cuales se dividieron según recibiesen digoxina endovenosa en urgencias o no. Se recogieron 51 variables relativas al paciente o al episodio de descompensación y se investigó el perfil del paciente tratado con digoxina en urgencias. Como variables evolutivas se investigaron la necesidad de ingreso, la estancia en urgencias prolongada (> 24 horas) en dados de alta y la hospitalización prolongada (> 7 días) en ingresados, y la mortalidad intrahospitalaria y a 30 días por cualquier causa. Se analizó si el tratamiento con digoxina se asoció a diferencias evolutivas, de forma cruda y ajustada a las características del paciente y el episodio de ICA. Resultados: Se analizaron 15.549 pacientes (mediana = 83 años, mujeres = 55%), de los que 1.430 (9,2%) fueron tratados con digoxina. La digoxina se utilizó más en mujeres, pacientes jóvenes, en mejor clase funcional de la New York Heart Association (NYHA), pero con descompensaciones más graves y, sobre todo, cuando existía una fibrilación auricular (FA) con respuesta ventricular rápida como desencadenante. Se hospitalizó el 75,4% de pacientes (más frecuente en tratados con digoxina; 81,6% vs 74,8%, p < 0,001), tuvo estancia prolongada en urgencias el 38,3% (52,9% vs 37,2%, p < 0,001), hospitalización prolongada el 48,1% (49,3% vs 47,9%, p = 0,385), mortalidad intrahospitalaria el 7,2% (6,9% vs 7,2%, p = 0,712) y a 30 días el 9,7% (9,3% vs 9,7%, p = 0,625). El modelo ajustado mostró que el uso de digoxina en urgencias sólo se asoció con estancia prolongada en urgencias (OR = 1,883, IC 95% = 1,359-2,608), pero no con la necesidad de ingreso, hospitalización prolongada o mortalidad.

Objectives: To analyze factors related to the use of digoxin to treat patients with acute heart failure (AHF) in emergency departments (EDs) and the impact of digoxin treatment on short-term outcomes. Methods: We included patients diagnosed with AHF in 45 Spanish EDs. The patients, who were not undergoing long-term treatment for heart failure, were classified according to whether or not they were given intravenous digoxin in the ED. Fifty-one patient or cardiac decompensation episode variables were recorded to profile ED patients treated with digoxin. Outcome variables studied were the need for hospital admission, prolonged stay in the ED (> 24 hours) for discharged patients, prolonged hospitalization (> 7 days) for admitted patients, and all-cause in-hospital or 30-day mortality. The associations between digoxin treatment and the outcomes were studied with odds ratios (ORs) adjusted for patient and AHF episode characteristics. Results: Data for 15 549 patients (median age, 83 years; 55% women) were analyzed; 1430 (9.2%) were treated with digoxin. Digoxin was used more often in women, young patients, and those with better New York Heart Association (NYHA) classifications but more severe cardiac decompensation, especially if the trigger was atrial fibrillation with rapid ventricular response. Admissions were ordered for 75.4% of the patients overall (81.6% of digoxin-treated patients vs 74.8% of nontreated patients; P < .001). The ED stay was prolonged in 38.3% of patients discharged from the ED (52.9% of digoxin-treated patients vs 37.2% of nontreated patients; P < .001). The duration of hospital stay was prolonged in 48.1% (digoxin-treated, 49.3% vs 47.9%; P = .385). In-hospital mortality was 7.2% overall (6.9% vs 7.2%, P= .712), and 30-day mortality was 9.7% (9.3% vs 9.7%, P = .625). ED use of digoxin was associated with a prolonged stay in the department (adjusted OR, 1.883; 95% CI, 1.359-2.608) but not with hospitalization or mortality. (AU)

RESUMO

OBJECTIVES: To analyze factors related to the use of digoxin to treat patients with acute heart failure (AHF) in emergency departments (EDs) and the impact of digoxin treatment on short-term outcomes. MATERIAL AND METHODS: We included patients diagnosed with AHF in 45 Spanish EDs. The patients, who were not undergoing long-term treatment for heart failure, were classified according to whether or not they were given intravenous digoxin in the ED. Fifty-one patient or cardiac decompensation episode variables were recorded to profile ED patients treated with digoxin. Outcome variables studied were the need for hospital admission, prolonged stay in the ED (> 24 hours) for discharged patients, prolonged hospitalization (> 7 days) for admitted patients, and all-cause in-hospital or 30-day mortality. The associations between digoxin treatment and the outcomes were studied with odds ratios (ORs) adjusted for patient and AHF episode characteristics. RESULTS: Data for 15 549 patients (median age, 83 years; 55% women) were analyzed; 1430 (9.2%) were treated with digoxin. Digoxin was used more often in women, young patients, and those with better New York Heart Association (NYHA) classifications but more severe cardiac decompensation, especially if the trigger was atrial fibrillation with rapid ventricular response. Admissions were ordered for 75.4% of the patients overall (81.6% of digoxin-treated patients vs 74.8% of nontreated patients; P .001). The ED stay was prolonged in 38.3% of patients discharged from the ED (52.9% of digoxin-treated patients vs 37.2% of nontreated patients; P .001). The duration of hospital stay was prolonged in 48.1% (digoxin-treated, 49.3% vs 47.9%; P = .385). In-hospital mortality was 7.2% overall (6.9% vs 7.2%, P= .712), and 30-day mortality was 9.7% (9.3% vs 9.7%, P = .625). ED use of digoxin was associated with a prolonged stay in the department (adjusted OR, 1.883; 95% CI, 1.359-2.608) but not with hospitalization or mortality. CONCLUSION: Digoxin continues to be used in one out of ten ED patients who are not already on long-term treatment with the drug. Digoxin use is associated with cardiac decompensation triggered by atrial fibrillation with rapid ventricular response, younger age, women, and patients with better initial NYHA function status but possibly more severe decompensation. Digoxin use leads to a longer ED stay but is safe, as it is not associated with need for admission, prolonged hospitalization, or short-term mortality.

CONCLUSIONES: La digoxina continúa utilizándose en uno de cada 10 pacientes con ICA atendidos en urgencias que no utilizaban este fármaco de manera habitual. Su uso se relaciona con un paciente cuya ICA ha sido descompensada por una FA con respuesta ventricular rápida, más joven y más frecuentemente mujer, en mejor clase funcional de la NYHA basal y con una descompensación posiblemente más grave. El uso de digoxina conlleva una estancia en urgencias más prolongada, pero su uso es seguro, pues no se asocia a la necesidad de ingreso, hospitalización prolongada o mortalidad a corto plazo.

RESUMO

Objetivos Analizar los factores relacionados con el tratamiento crónico inadecuado con digoxina, y si esta inadecuación impacta en la evolución a corto plazo. Método Se incluyeron pacientes diagnosticados de insuficiencia cardiaca aguda (ICA) en tratamiento crónico con digoxina, y se clasificaron como con tratamiento indicado o no indicado, investigándose los factores asociados a este hecho, y si se asociaba a mortalidad intrahospitalaria a 30 días, estancia hospitalaria prolongada (>7 días) y evento adverso combinado (reconsulta a urgencias, hospitalización por ICA o muerte por cualquier causa) durante los 30 días postalta. Resultados Se analizaron 2.366 pacientes en tratamiento crónico con digoxina (mediana=83 años, mujeres=61%): adecuado en 1.373 casos (58,0%), inadecuado en 993 (42,0%). La inadecuación se asoció con mayor edad, menor comorbilidad, menor tratamiento con betabloqueantes e IECA, mejor función ventricular y peor índice de Barthel. La mortalidad intrahospitalaria y a 30 días fue mayor en pacientes con tratamiento inadecuado (9,9 versus 7,6%, p=0,05; y 12,6 versus 9,1%, p<0,001; respectivamente); no hubo diferencias en estancia prolongada (35,7 versus 33,8%) ni en eventos adversos posalta (32,9 versus 31,8%). Ajustando las diferencias basales y del episodio de descompensación, el tratamiento crónico inadecuado con digoxina no se asoció con ningún resultado, con odds ratio de 1,31 (IC 95%: 0,85-2,03) para mortalidad intrahospitalaria, 1,29 (0,74-2,25) para mortalidad a 30 días; 1,07 (0,82-1,40) para estancia prolongada y 0,88 (0,65-1,19) para evento adverso posalta. Conclusión Existe un perfil de paciente que recibe de forma inadecuada tratamiento crónico con digoxina, si bien ello no se asocia con resultados adversos a corto plazo durante los episodios de ICA (AU)


Objectives To analyze the factors related to inadequate chronic treatment with digoxin and whether the inadequacy of treatment has an impact on short-term outcome. Method Patients diagnosed with AHF who were in chronic treatment with digoxin were selected. Digoxin treatment was classified as adequate or inadequate. We investigated factors associated to inadequacy and whether such inadequacy was associated with in-hospital and 30-day mortality, prolonged hospital stay (>7 days) and combined adverse event (re-consultation to the ED or hospitalization for AHF or death from any cause) during the 30 days after discharge. Results We analyzed 2366 patients on chronic digoxin treatment (median age=83 years, women=61%), which was considered adequate in 1373 cases (58.0%) and inadequate in 993 (42.0%). The inadequacy was associated with older age, less comorbidity, less treatment with beta-blockers and renin–angiotensin inhibitors, better ventricular function, and worse Barthel index. In-hospital and 30-day mortality was higher in patients with inadequate digoxin treatment (9.9% vs. 7.6%, p=0.05; and 12.6% vs. 9.1%, p<0.001, respectively). No differences were recorded in prolonged stay (35.7% vs. 33.8%) or post-discharge adverse events (32.9% vs. 31.8%). In the model adjusted for baseline and decompensation episode differences, inadequate treatment with digoxin was not significantly associated with any outcome, with an odds ratio of 1.31 (95% CI=0.85-2.03) for in-hospital mortality; 1.29 (0.74-2.25) for 30-day mortality; 1.07 (0.82-1.40) for prolonged stay; and 0.88 (0.65-1.19) for post-discharge adverse event. Conclusion There is a profile of patients with AHF who inadequately receive digoxin, although this inadequateness for chronic digitalis treatment was not associated with short-term adverse outcomes (AU)

RESUMO

OBJECTIVES: Digoxin toxicity accounts for a small percentage of poisonings attended by emergency departments. This study aimed to describe differences between acute and chronic digoxin toxicity and assess the use of digoxin-specific antibody fragments (digoxin-Fab) as an antidote. MATERIAL AND METHODS: Retrospective, observational, multicenter study in 15 hospital emergency departments in 8 Spanish autonomous communities in 7 years. We collected patient, clinical and treatment variables, and discharge destination. Patients were classified according to whether toxicity was acute or chronic and whether digoxin-Fab was administered or not. RESULTS: Twenty-seven acute and 631 chronic digoxin poisonings were attended. The mean (SD) patient age was 83.9 (7.9) years, and 76.9% were women. Patients with acute toxicity were younger (80.0 [12] years) than those with chronic toxicity (84.1 [7.7] years) (P .038), and accidental poisoning was less common (in 85.2% vs 100% in chronic toxicity; P .001). Cases of acute toxicity were also more serious (Poison Severity Score (29.6% vs 12.5% in chronic toxicity; P .001). Thirty-four patients were treated with digoxin-Fab (5.4%). These patients were younger (78.7 [11.5] years vs 84.2 (7.6) years), their toxicity was more often acute (in 20.6% vs 3.2% in chronic toxicity), more had attempted suicide (8.8% vs 0.2% with chronic toxicity), and more had severe symptoms (50% vs 11.2%) (P .001, all comparisons). Hospital admission was required for 76.1%. Overall, mortality was 11.4%. CONCLUSION: Chronic toxicity accounts for most digoxin poisoning cases, and most patients are women. Acute toxicity is more serious. Patients who required digoxin-Fab have more severe poisoning. Such patients usually have acute toxicity, and attempted suicide is more often the reason for the emergency.


OBJETIVO: Las intoxicaciones por digoxina representan un pequeño porcentaje de las intoxicaciones atendidas en urgencias. El objetivo de este estudio fue describir las diferencias entre intoxicaciones agudas y crónicas y evaluar la administración de su antídoto específico: los anticuerpos antidigoxina (AcAD). METODO: Estudio retrospectivo, observacional y multicéntrico en 15 servicios de urgencias hospitalarios de 8 comunidades autónomas durante 7 años. Se recogieron datos de filiación, clínica, tratamiento y destino al alta. Los pacientes se dividieron según era la intoxicación aguda o crónica y según recibían o no AcAD. RESULTADOS: Se recogieron 27 intoxicaciones agudas y 631 crónicas. La edad media fue de 83,9 (7,9) años, y el 76,9% eran mujeres. Los pacientes con intoxicación aguda tenían menor edad media (80,0 (12) vs 84,1 (7,7) años; p 0,038), y porcentaje de causa accidental (85,2% vs 100%; p 0,001) y mayor gravedad en la escala Poison Severity Score (29,6% vs 12,5%; p 0,001). Treinta y cuatro pacientes recibieron AcAD (5,4%) y constituyen un grupo de menor edad [78,7 (11,5) vs 84,2 (7,6); p 0,001], con mayor porcentaje de intoxicaciones agudas (20,6% vs 3,2%), intencionalidad suicida (8,8% vs 0,2%) y gravedad (50% vs 11,2%, p 0,001 en todas las comparaciones). El 76,1% precisó ingreso. La mortalidad fue del 11,4%. CONCLUSIONES: Las intoxicaciones por digoxina suelen ser crónicas y predominan en mujeres. Las intoxicaciones agudas son de mayor gravedad. Los pacientes que precisaron administración de AcAD tenían intoxicaciones más graves y mayor porcentaje de intoxicaciones agudas y con intencionalidad suicida.

RESUMO

Objetivo: Resumir la literatura disponible sobre los estudios de farmacocinética poblacional de digoxina en pacientes de edad avanzada e identificar los cambios fisiopatológicos en esta subpoblación, que conllevanimplicaciones clínicas en la farmacocinética de la digoxina.Método: Se realizó una revisión sistemática de los estudios de farmacocinética poblacional en pacientes ancianos que recibían digoxina.Se utilizaron PubMed, ISI Web of Science, SCOPUS y Science Directpara identificar los artículos con los descriptores (“Digoxin”[Mesh]) AND(“Pharmacokinetics”[Mesh]) AND (“Aged”[Mesh] OR “Elderly”[Mesh]),seguido de una búsqueda manual.Resultados: Se encontraron y revisaron nueve estudios, cinco de loscuales de desarrollaron en pacientes asiáticos. Se utilizó NONMEMpara el análisis farmacocinético de los niveles plasmáticos de la digoxina, mayoritariamente descrita como un modelo monocompartimental.Conclusiones: Los pacientes ancianos presentan cambios fisiopatológicos con gran influencia en la farmacocinética de muchos fármacos. Lascovariables con un mayor impacto en la farmacocinética de la digoxinadeben tenerse en cuenta al ajustar la dosis de este medicamento enpacientes de edad avanzada con el fin de lograr beneficios óptimospara la salud y prevenir posibles efectos adversos en esta subpoblación. (AU)


Objective: To resume the available literature about digoxin populationpharmacokinetic studies in elderly patients. To identify the pathophysiological changes in this subpopulation with clinical implications on digoxinpharmacokinetics.Method: A systematic review was performed regarding the population pharmacokinetic studies in elderly patients receiving digoxin. PubMed, ISI Web of Science, SCOPUS and Science Direct were usedto identify the articles with the descriptors (“Digoxin”[Mesh]) AND(“Pharmacokinetics”[Mesh]) AND (“Aged”[Mesh] OR “Elderly”[Mesh]),followed by a manual search.Results: Nine studies were found and reviewed, five of them carriedout in Asian patients. NONMEM was used for pharmacokinetic analysisof digoxin blood levels, being mostly described by a one-compartmentmodel. Serum creatinine, body weight and concomitant administration ofcalcium channel blockers are the covariates that most frequently influencedigoxin pharmacokinetics in elderly patients.Conclusions: Elderly people present pathophysiological changes withinfluence on the pharmacokinetics of many drugs. The covariates withmost influence on digoxin pharmacokinetics should be considered whenadjusting this drug dosage in elder patients to achieve optimum healthbenefits and prevent possible side effects.

RESUMO

Introducción: La digoxina se caracteriza por estrecho margen terapéutico que hace dificultosa su dosificación y sea necesaria una monitorización de sus niveles séricos. Esto se hace más complejo en pacientes con nefropatía crónica que precisan de un mayor ajuste de dosis.Desarrollo de la experiencia:Presentamos el caso de una mujer de 88 años admitida en nuestra unidad en tratamiento con digoxina oral por insuficiencia cardiaca crónica con pauta de 1 comprimido diario con descanso los fines de semana, que presenta mal control de síntomas y niveles séricos de digoxina infraterapéuticos en controles. Al cambiar la formulación a jarabe oral pediátrico (Lanacordin® 0,05mg/mL) se consiguió un mejor nivel de los niveles del fármaco y del control de síntomas.Conclusiones:La utilización de la digoxina en jarabe oral puede ser una alternativa a la formulación con comprimidos, sobre todo en pacientes en los que el control de los niveles del fármaco puede resultar complejo por sus comorbilidades. (AU)


Introduction: Digoxin is characterized by narrow therapeutic margin which makes its dosing difficult and monitoring of its serum levels necessary. This becomes more complex in patients with chronic nephropathy who require a greater dose adjustment.Development of the experience:We present the case of an 88-year-old woman admitted to our unit under treatment with oral digoxin for chronic heart failure with a regimen of 1 tablet daily with rest at weekends, who presented poor symptom control and subtherapeutic serum digoxin levels in controls. Changing the formulation to pediatric oral syrup (Lanacordin® 0.05mg/mL) resulted in better drug levels and symptom control.Conclusions:The use of digoxin in oral syrup may be an alternative to tablet formulation, especially in patients in whom drug level control may be complex due to their comorbidities.

En situaciones de riesgo vital asociadas a una intoxicación digitálica están indicados los fragmentos de unión al antígeno (Fab) antidigoxina cuya eliminación es mayoritariamente renal. Las alteraciones cardiacas asociadas a esta intoxicación pueden traducirse en oligoanuria. Dado que ni la digoxina, ni los complejos Fab-digoxina pueden eliminarse por hemofiltración o hemodiálisis, la presencia de insuficiencia renal es una limitación importante para el tratamiento de pacientes con intoxicación digitálica con Fab antidigoxina. Se describe el caso de una paciente con insuficiencia renal e intoxicación digitálica a la que se le administran en 2 ocasiones Fab antidigoxina. A las 61 horas de la primera administración se observó un rebote en los niveles de digoxina. Esta misma situación se repitió a las 38 horas de la segunda administración del antídoto. Encontramos una correlación entre el estado clínico de la paciente y las determinaciones analíticas, lo que sugiere que, tras las dos administraciones del antídoto, se produjo un efecto rebote.

Anti-digoxin antigen-binding fragments (Fab) are indicated in life-threatening situations associated with digitalis toxicity. The elimination of anti-digoxin Fab occurs through the renal route. The cardiac alterations associated with this toxicity translate into oligoanuria. Since neither digoxin nor Fab-digoxin complexes can be removed by hemofiltration or hemodialysis, the presence of renal failure is an important limitation for the treatment with anti-digoxin Fab of patients with digitalis toxicity. The case of a patient with renal insufficiency and digitalis toxicity is described, who were administered Fab antidigoxin on 2 occasions. At 61 hours after the first administration, a rebound effect in digoxin levels was observed. This same situation was repeated 38 hours after the second administration of the antidote. We found a correlation between the patient’s clinical status and the analytical determinations, which suggests that, after the two administrations of the antidote, there was a rebound effect.(AU)

RESUMO

El posaconazol es un inhibidor de la glicoproteína P (P-gp), un transportador dependiente del ATP que desempeña un papel importante en la absorción, distribución y eliminación de múltiples medicamentos. Varios estudios in vitro han demostrado que la digoxina es un sustrato de la P-gp, por lo que su administración concomitante puede dar lugar a un aumento de la absorción intestinal y/o a una disminución de la depuración renal, con el consiguiente riesgo de toxicidad digitálica. Se presenta el caso clínico de una intoxicación digitálica como consecuencia de la interacción entre posaconazol y digoxina en un paciente con fibrilación auricular, insuficiencia cardiaca y múltiples episodios de pancitopenia postquimioterapia por leucemia mieloide aguda. El paciente tuvo que ser hospitalizado por bradicardia de 30 l.p.m. Ambos medicamentos fueron suspendidos de inmediato y el paciente se recuperó sin incidencias. (AU)


Posaconazole is an inhibitor of glycoprotein P (P-gp), an ATP-dependent transporter with a role in drug absorption, distribution and elimination. Several in vitro studies have shown that digoxin is a substrate of P-gp, so concomitant administration may result in increased intestinal absorption and/or decreased renal clearance, with a consequent risk of digitalic toxicity. The clinical case of digitalis intoxication as a consequence of the interaction between posaconazole and digoxin in a patient with atrial fibrillation, congestic heart failure and multiple episodes of post chemotherapy pancytopenia due to acute myeloid leukemia is weighed. The patient had to be hospitalized for bradicardia of 30 l.p.m. Both medicines were immediately suspended and the patient recovered without major issues. (AU)

RESUMO

INTRODUCTION AND OBJECTIVES: Ivabradine is an inhibitor of the If channel, the main determinant of the pacemaker function of the sinus node. The drug has been approved for the treatment of angina and heart failure. There is some evidence of its role as an inhibitor of atrial-ventricular node (AVN) conduction. The aim of the BRAKE-AF project is to assess ivabradine use for rate control in atrial fibrillation (AF). METHODS: A multicenter, randomized, parallel, open-label, noninferiority phase III clinical trial will be conducted to compare ivabradine vs digoxin in 232 patients with uncontrolled permanent AF despite beta-blockers or calcium channel blockers. The primary efficacy endpoint is the reduction in daytime heart rate measured by 24-hour Holter monitoring at 3 months. This clinical trial will be supported by an electrophysiological study of the effect of ivabradine on the action potential of the human AVN. To do this, an experimental model will be used with Chinese hamster ovarium cells transfected with the DNA encoding the expression of the t channels involved in this action potential and recording of the ionic currents with patch clamp techniques. RESULTS: New data will be obtained on the effect of ivabradine on the human AVN and its safety and efficacy in patients with permanent AF. CONCLUSIONS: The results of the BRAKE-AF project might allow inclusion of ivabradine within the limited arsenal of drugs currently available for rate control in AF.

RESUMO

OBJECTIVES: Digoxin poisoning is a frequent reason for seeking emergency care. This study aimed to assess mortality related to digoxin poisoning. MATERIAL AND METHODS: Descriptive observational study of digoxin poisonings attended in the emergency departments of 4 hospitals in Catalonia from 2013 through 2015. We gathered data relevant to the poisonings and recorded immediate and 30-day mortality. Factors possibly related to mortality were explored. RESULTS: A total of 171 digoxin poisonings were attended. Seven (4.1%) were acute and 164 (95.9%) were chronic. The immediate and 30-day mortality rates were 6.4% and 13.4%, respectively. Bivariate analysis did not identify factors related to immediate mortality. However, the variables more often associated with 30-day mortality in this analysis were acute poisoning (after which 13% died vs 2.7% of those with chronic poisoning, P=.05), suicide attempts (8.7% of whom died vs 0.7%, P=.048), more compromised renal function (21.7% vs 9.5%, P=.037), fewer neurologic symptoms (4.3% vs 17.8% with more symptoms, P=.005), higher mean digoxin concentrations (4.7 mg/dL in those who died vs 3.7 mg/dL, P=.027), and a lower Barthel index (mean [SD] 49.1 [33.4] in those who died vs 70.3 [28.5]; P=.006). Logistic regression analysis identified serum digoxin concentration to be independently associated with immediate mortality. A lower Barthel index was associated with 30-day mortality. CONCLUSION: Immediate mortality is related to a high digoxin concentration in serum, and 30-day mortality to a low Barthel index.


OBJETIVO: La intoxicación digitálica es un motivo frecuente de consulta en los servicios de urgencias hospitalarios (SUH). El objetivo de este estudio es conocer la mortalidad asociada a dicha intoxicación. METODO: Estudio descriptivo y observacional de las intoxicaciones digitálicas atendidas en los SUH de 4 hospitales de Cataluña durante los años 2013-15. Se recogieron datos relativos a la intoxicación, la mortalidad inmediata y a los 30 días. Se analizó la existencia de posibles factores asociados a la mortalidad. RESULTADOS: Se registraron 171 intoxicaciones digitálicas. Siete eran agudas (4,1%) y 164 (95,9%) crónicas. La mortalidad inmediata fue del 6,4% y a los 30 días fue del 13,4%. El análisis binario no identificó ningún factor relacionado con la mortalidad inmediata. En cuanto a la mortalidad a 30 días, los pacientes que fallecieron tenían con mayor frecuencia una intoxicación aguda (13% vs 2,7%; p = 0,05), había más intoxicaciones con intencionalidad suicida (8,7% vs 0,7%; p = 0,048), más afectación renal (21,7% vs 9,5%; p = 0,037), menos sintomatología neurológica (4,3% vs 17,8%; p = 0,005), mayor digoxinemia (4,7 mg/dl vs 3,7 mg/dl; p = 0,027) y menor puntuación en el índice de Barthel (IB) (49,1 (33,4) vs 70,3 (28,5); p = 0,006). El análisis de regresión logística identificó la digoxinemia como un factor independiente de mortalidad inmediata y la puntuación en el IB en la mortalidad a 30 días. CONCLUSIONES: La digoxinemia se relaciona con la mortalidad inmediata y el IB se relaciona con la mortalidad a 30 días.

RESUMO

A taquicardia fetal ocorre em 0,4-0,6% de todas as gestações. Das taquiarritmias fetais sustentadas, o flutter atrial é a segunda mais comum. Quando não tratada corretamente, causa insuficiência cardíaca fetal e pode ser necessária a interrupção precoce da gestação. O diagnóstico das taquiarritmias é feito, principalmente, pela ecocardiografiaintraútero. O tratamento de primeira escolha é a administração oral materna de digoxina. Caso não haja resposta adequada ou o feto evolua com hidropisia, é necessário associar outro antiarrítmico como sotalol ou amiodarona. Neste relato, iniciou-se com digoxina; e, em função da ausência de resposta, foi associada propafenona. Sotalol ou amiodarona não foram usados devido à bradicardia e à hipotensão materna.


Fetal tachycardia occurs in 0.4 - 0.6% of all pregnancies. Out of the sustained fetal tachyarrhythmias, the atrial flutter is the second most common. It causes fetal heart failure when not properly treated, and early pregnancy interruption may be required. The diagnosis of tachyarrhythmias is mainly achieved by intra-uterus echocardiography. The first choice treatment is the maternal oral administration of digoxin. The association with other antiarrhythmics such as sotalol or amiodarone is needed if there is no response to digoxin or if the fetus evolves with dropsy. In this case report, the treatment began with digoxin and because there was no response, it was associated with propafenone. Sotalol or amiodarone were not used due to maternal bradycardia and hypotension.

RESUMO

INTRODUCTION AND OBJECTIVES: We aimed to assess and compare the effect of digoxin on clinical outcomes in patients with atrial fibrillation vs those under beta-blockers or none of these drugs. METHODS: AFBAR is a prospective registry study carried out by a team of primary care physicians (n=777 patients). Primary endpoints were survival, survival free of admission due to any cause, and survival free of admission due to cardiovascular causes. The mean follow up was 2.9 years. Four groups were analyzed: patients receiving digoxin, beta-blockers, or digoxin plus beta-blockers, and patients receiving none of these drugs. RESULTS: Overall, 212 patients (27.28%) received digoxin as the only heart control strategy, 184 received beta-blockers (23.68%), 58 (7.46%) were administered both, and 323 (41.57%) received none of these drugs. Digoxin was not associated with all-cause mortality (estimated hazard ratio=1.42; 95% confidence interval, 0.77-2.60; P=.2), admission due to any cause (estimated hazard ratio=1.03; 95% confidence interval, 0.710-1.498; P=.8), or admission due to cardiovascular causes (estimated hazard ratio=1.193; 95% confidence interval, 0.725-1.965; P=.4). No association was found between digoxin use and all-cause mortality, admission due to any cause, or admission due to cardiovascular causes in patients without heart failure. There was no interaction between digoxin use and sex in all-cause mortality or in survival free of admission due to any cause. However, an association was found between sex and admission due to cardiovascular causes. CONCLUSIONS: Digoxin was not associated with increased all-cause mortality, survival free of admission due to any cause, or admission due to cardiovascular causes, regardless of underlying heart failure.

RESUMO

Digitalis purpurea L. es una de las principales fuentes de cardenólidos tales como digoxina y digitoxina. Estos fármacos son ampliamente usados en la disfunción cardíaca y para regular las arritmias del corazón. El presente trabajo se realizó con el objetivo de estudiar el efecto de tres elicitores en el cultivo de brotes de Digitalis purpurea var. Roter Berggold para incrementar la producción in vitro de cardenólidos. La elicitación es una estrategia para incrementar la producción de biomasa y metabolitos secundarios en el cultivo in vitro. Los elicitores evaluados fueron ChitoPlant (0,001; 0,01; 0,1 g.L-1); SilioPlant (0,01; 0,1; 1,0 g.L-1) y Jasmonato de metilo (60, 80 y 100 µM), descritos por primera vez para el incremento de cardenólidos. Se demostró que la elicitación es una estrategia viable para el incremento de cardenólidos en brotes de D. purpurea. El ChitoPlant®, redujo la altura sin afectación en el resto de las variables morfológicas evaluadas. Además indujo un incremento significativo en el contenido de cardenólidos. El SilioPlant® (0,01 g.L-1) no provocó afectaciones en la biomasa e incrementó significativamente la síntesis de cardenólidos en los brotes en 3,6 y 6,9 veces el contenido de digoxina y digitoxina respectivamente. La elicitación con el jasmonato de metilo provocó una reducción de la biomasa. Los contenidos de digoxina y digitoxina se incrementaron ligera y significativamente con 80 y 100 µM de jasmonato de metilo respectivamente. El mejor resultado integral se obtuvo con 0,01 g.L-1 de SilioPlant, el cual indujo la mayor producción neta de cardenólidos por frasco de cultivo (4,72 µg digoxina y 88,27 µg digitoxina).


Digitalis purpurea L. is one of the main sources of cardenolides such as digitoxin and digoxin. These drugs are widely used to strengthen cardiac diffusion and to regulate heart rhythm. The aim of this study was to evaluate the influence of three elicitors on shoots of Digitalis purpurea var. Roter Berggold in semisolid media in order to increase cardenolides biosynthesis. Elicitation is a strategy to increase biomass and secondary metabolites production on in vitro cultures. The elicitors evaluated were ChitoPlant (0,001; 0,01; 0,1 g.L-1); SilioPlant (0,01; 0,1; 1,0 g.L-1) and Methyl jasmonate (60, 80, 100 µM), which are reported here to induce cardenolide production for first time. Elicitation resulted an effective strategy to increase cardenolide production on D. purpurea shoot cultures. ChitoPlant induced a decrease in shoots length, but had no effect on the rest of morphological parameters evaluated. As well, ChitoPlant increased cardenolide content. SilioPlant (0,01 g.L-1) did not affect biomass production and at the same time, increased in 3,6-fold and 6,9-fold digoxin and digitoxin content respectively. Elicitation with Methyl jasmonate resulted in decreased biomass production. Digoxin and digitoxin content was slight and significantly increased by Methyl jasmonate 80 and 100 µM respectively. The best integral result was reached with 0,01 g.L-1 of SilioPlant, which induced the highest net yields per culture flask (4,72 µg of digoxin and 88,27 µg of digitoxin).

RESUMO

Introducción: la electrocardiografía fetal constituye la prueba de oro para el diagnóstico de las arritmias en la vida posnatal, algo difícil de lograr en la vida prenatal incluso con la ecografía prenatal de alta resolución. Las taquiarritmias supraventriculares son las que se manifiestan con frecuencias cardíacas superiores a 180 latidos por min y pueden asociarse a mortalidad fetal en un tercio de los casos, sobre todo cuando se asocia a hidropesía fetal o cuando se establece por más de 15 días. El tratamiento permite la reversión de la arritmia o el control ventricular en el menor tiempo posible.Objetivos: comprobar la respuesta intraútero de la taquiarritmia al tratamiento farmacológico.Métodos: se realizó un estudio descriptivo prospectivo observacional de un universo de 24 fetos con el diagnóstico de taquiarritmia fetal que se diagnosticaron y atendieron en el Departamento Provincial de Genética de La Habana y en el Hospital Ginecobstétrico Ramón González Coro entre los años 2003 y 2012.Resultados: las taquiarritmias se observaron en 24 fetos (40,6 por ciento). Las madres menores 30 años fueron las más representadas en el grupo de mujeres del estudio, unido al índice de masa corporal sobrepeso y específicamente las pacientes nulíparas. Casi la mitad de la muestra no requirió tratamiento farmacológico (45,8 por ciento) todas con el diagnóstico ecocardiográfico de extrasístoles y sola una con compromiso orgánico del corazón.Conclusiones: la flecainida se utilizó, en la cuarta parte de la muestra y mostró una resolutividad de 83,3 por ciento en los fetos intraútero. La sobrevida de los fetos tratados farmacológicamente por vía oral fue 100 por ciento(AU)


Introduction: fetal electrocardiography is the gold standard for diagnosis of arrhythmias in postnatal life. This is difficult to achieve in prenatal life even with high-resolution prenatal ultrasound. Supraventricular tachyarrhythmias are manifested with heart rates above 180 beats per min and may be associated with fetal death in one third of cases, especially when associated with fetal hydrops or when it is set for over 15 days. Treatment allows the reversal of ventricular arrhythmia or control in the shortest possible time. Objective: to test tachyarrhythmia in uterus response to drug treatment. Methods: an observational prospective descriptive study was conducted in a universe of 24 fetuses with the diagnosis of fetal tachyarrhythmia that were diagnosed and treated at the Provincial Department of Genetics, Havana and at the Ramón González Coro Maternal Hospital from 2003 to 2012. Results: tachyarrhythmias were observed in 24 fetuses 40.6 percent. Mothers younger than 30 were the most represented in this study group, together with BMI overweight and nulliparous patients specifically. Almost half of the sample did not require drug 45.8 percent treatment, all with extrasystoles echocardiographic diagnosis and only one with organic heart involvement. Conclusions: flecainide was used in a quarter of the sample and showed 83.3 percent resoluteness of fetuses in uterus. Survival of fetuses pharmacologically orally treated was 100 percent(AU)
