¿Se ha producido un cambio en la etiología del ictus isquémico en las últimas décadas? Análisis y comparación de una base de datos de ictus actual frente a las históricas / Has the aetiology of ischaemic stroke changed in the past decades? Analysis and comparison of data from current and historical stroke databases

OBJETIVOS: Comprobar si han existido variaciones en la etiología del ictus isquémico en los últimos años e investigar las posibles causas que lo justifiquen. PACIENTES Y MÉTODOS: Análisis de los antecedentes epidemiológicos y factores de riesgo vascular de los pacientes diagnosticados de ictus isquémico en el Complejo Hospitalario Universitario de Albacete (CHUA) entre 2009 y 2014. La clasificación etiológica del ictus isquémico se realizó según los criterios TOAST. Se compararon los resultados con los de la clásica Stroke Data Bank (SDB) y se contrastaron ambas series con otros registros hospitalarios publicados en el periodo que las separa. RESULTADOS: Se analiza a 1.664 pacientes, 58% varones, mediana de edad 74 años. Según la clasificación etiológica los resultados obtenidos son (CHUA/SDB): aterotrombóticos (12%/9%), lacunares (13%/25%), cardioembólicos (32%/19%), causa infrecuente (3%/4%) e indeterminados (40%/44%). El 63% de los pacientes del CHUA era mayor de 70 años, en la SDB solo el 42% superaba esa edad. En ambos registros el subtipo cardioembólico era más prevalente en mayores de 70 años. La HTA no tratada era más frecuente en la SDB (SDB = 31% vs. CHUA = 10%). El análisis de otras bases de datos muestra una tendencia progresiva a escala mundial al aumento en la prevalencia del ictus cardioembólico. CONCLUSIONES: Nuestro estudio muestra tanto en nuestro centro como a escala mundial una disminución del porcentaje de ictus lacunares y un aumento del de cardioembólicos respecto a la SDB. Estas diferencias pudieran justificarse por el envejecimiento de los pacientes, el mejor control de la HTA actualmente y mayor capacidad para detectar arritmias cardioembólicas en las Unidades de Ictus

OBJECTIVES: We aimed to determine whether the aetiology of ischaemic stroke has changed in recent years and, if so, to ascertain the possible reasons for these changes. PATIENTS AND METHODS: We analysed the epidemiological history and vascular risk factors of all patients diagnosed with ischaemic stroke at Complejo Hospitalario Universitario de Albacete (CHUA) from 2009 to 2014. Ischaemic stroke subtypes were established using the TOAST criteria. Our results were compared to data from the classic Stroke Data Bank (SDB); in addition, both series were compared to those of other hospital databases covering the period between the two. RESULTS: We analysed 1664 patients (58% were men) with a mean age of 74 years. Stroke aetiology in both series (CHUA, SDB) was as follows: atherosclerosis (12%, 9%), small-vessel occlusion (13%, 25%), cardioembolism (32%, 19%), stroke of other determined aetiology (3%, 4%), and stroke of undetermined aetiology (40%, 44%). Sixty-three percent of the patients from the CHUA and 42% of the patients from the SDB were older than 70 years. Cardioembolic strokes were more prevalent in patients older than 70 years in both series. Untreated hypertension was more frequent in the SDB (SDB = 31% vs CHUA = 10%). The analysis of other databases shows that the prevalence of cardioembolic stroke is increasing worldwide. CONCLUSIONS: Our data show that the prevalence of lacunar strokes is decreasing worldwide whereas cardioembolic strokes are increasingly more frequent in both our hospital and other series compared to the SDB. These differences may be explained by population ageing and the improvements in management of hypertension and detection of cardioembolic arrhythmias in stroke units

Assessment of efficacy and safety of eslicarbazepine acetate for the treatment of trigeminal neuralgia.

BACKGROUND: Antiepileptic drugs are the first-line treatment for trigeminal neuralgia (TN). Carbamazepine and oxcarbazepine are the most studied with well-known efficacy. Eslicarbazepine acetate is a third-generation antiepileptic drug that has not previously been evaluated for the treatment of TN. We aim to assess the efficacy, tolerability and safety of eslicarbazepine for TN. DESIGN AND METHODS: Retrospective, open-label, multicentric, intention-to-treat study. We included patients older than 18 years who met the ICHD-3 beta diagnostic criteria for TN. We evaluated the variation of intensity and frequency of pain paroxysms before and after treatment with eslicarbazepine. Secondary objectives assessed were tolerability and safety of eslicarbazepine. RESULTS: Eighteen patients were included, 15 women, mean age 65.2 years old, mean follow-up 21.1 months. The mean number of drugs tested before eslicarbazepine was 2; 10 patients used eslicarbazepine as monotherapy. After the treatment with ESL, the median of pain intensity improved from 9.5 to 2.5 (p < 0.001) and the median of pain paroxysms frequency improved from 70 episodes per week to 0.37 (p < 0.001). Responder rate was 88.9%; 44.4% became asymptomatic after treatment. Sixty-one per cent of patients presented some adverse event; four patients discontinued eslicarbazepine for this reason. Despite this, 16 patients (88.9%) noticed a good subjective tolerance to eslicarbazepine. The retention rate at 6 months was 77.8% and at 12 months 61.1%. CONCLUSIONS: Our study supports the hypothesis that eslicarbazepine acetate is an effective, safe and well-tolerated treatment for the treatment of TN. Further studies are warranted to corroborate these results. SIGNIFICANCE: Eslicarbazepine acetate has shown to be an effective, safe and well-tolerated drug for TN. This is the first study that evaluated the efficacy of this drug on TN in humans.
