[Alzemon: a prospective follow-up study of eslicarbazepine acetate monotherapy in patients with newly diagnosed epilepsy]. / Alzemon: estudio de seguimiento prospectivo del acetato de eslicarbacepina en monoterapia en pacientes con epilepsia de diagnóstico reciente.

INTRODUCTION: Eslicarbazepine acetate is a novel sodium channel blocker for use in the treatment of focal onset seizures. Prospective studies on its effectiveness in monotherapy in patients with newly diagnosed partial epilepsy in routine clinical practice are scarce. AIM: To evaluate the effectiveness of eslicarbazepine as initial monotherapy in patients with newly diagnosed partial epilepsy in routine clinical practice. PATIENTS AND METHODS: A prospective, multicentre, post-authorisation study. Patients with newly diagnosed partial epilepsy aged 18 years or older without previous treatment were included. The efficacy variables were: percentage of seizure-free patients, responders and reduction in monthly frequency of seizures. The safety variables analyse the 12-month retention rate and the occurrence of adverse effects. RESULTS: Fifty-three patients were included. The retention rate was 77.4%. At the end of the observation period, 83% of patients were seizure-free and 92.5% had reduced their baseline frequency by 50% or more. In addition, 68% of the patients reported some adverse effect and 7.5% of them dropped out of the study for this reason. The effectiveness analysis of the subgroup of patients aged 65 years or more showed no differences with respect to the overall population. CONCLUSION: Eslicarbazepine monotherapy in patients with newly diagnosed partial epilepsy, both in the general population and in the population over 65 years old, is effective and safe in routine clinical practice.

TITLE: Alzemon: estudio de seguimiento prospectivo del acetato de eslicarbacepina en monoterapia en pacientes con epilepsia de diagnóstico reciente.Introducción. El acetato de eslicarbacepina es un nuevo bloqueante de los canales de sodio en el tratamiento de las crisis de inicio focal. Los estudios prospectivos sobre su efectividad en monoterapia en pacientes con epilepsia parcial de reciente diagnóstico en la práctica clínica habitual son escasos. Objetivo. Evaluar la efectividad de la eslicarbacepina en monoterapia de inicio en pacientes con epilepsia parcial de reciente diagnóstico en la práctica clínica habitual. Pacientes y métodos. Estudio postautorización prospectivo y multicéntrico. Se incluyó a pacientes con epilepsia parcial de reciente diagnóstico de 18 años o más sin tratamiento previo. Las variables de eficacia fueron: porcentaje de pacientes libres de crisis, respondedores y reducción en la frecuencia mensual de crisis. Las variables de seguridad analizan la tasa de retención a los 12 meses y la aparición de efectos adversos. Resultados. Se incluyó a 53 pacientes. La tasa de retención fue del 77,4%. Al final del período de observación, el 83% de los pacientes se encontraba libre de crisis y el 92,5% había reducido en un 50% o más su frecuencia basal. El 68% de los pacientes notificó algún efecto adverso y el 7,5% de ellos abandonó el estudio por este motivo. El análisis de efectividad del subgrupo de 65 años o más no mostró diferencias respecto a la población global. Conclusión. La eslicarbacepina en monoterapia en pacientes con epilepsia parcial de reciente diagnóstico, tanto en la población general como en la población de más de 65 años, es eficaz y segura en la práctica clínica habitual.

EARLY-ESLI study: Long-term experience with eslicarbazepine acetate after first monotherapy failure.

PURPOSE: Evaluate real-life experience with eslicarbazepine acetate (ESL) after first monotherapy failure in a large series of patients with focal epilepsy. METHOD: Multicentre, retrospective, 1-year, observational study in patients older than 18 years, with focal epilepsy, who had failed first antiepileptic drug monotherapy and who received ESL. Data from clinical records were analysed at baseline, 3, 6 and 12 months to assess effectiveness and tolerability. RESULTS: Eslicarbazepine acetate was initiated in 253 patients. The 1-year retention rate was 92.9%, and the final median dose of ESL was 800 mg. At 12 months, 62.3% of patients had been seizure free for 6 months; 37.3% had been seizure free for 1 year. During follow-up, 31.6% of the patients reported ESL-related adverse events (AEs), most commonly somnolence (8.7%) and dizziness (5.1%), and 3.6% discontinued due to AEs. Hyponatraemia was observed in seven patients (2.8%). After starting ESL, 137 patients (54.2%) withdrew the prior monotherapy and converted to ESL monotherapy; 75.9% were seizure free, 87.6% were responders, 4.4% worsened, and 23.4% reported ESL-related AEs. CONCLUSION: Use of ESL after first monotherapy failure was associated with an optimal seizure control and tolerability profile. Over half of patients were converted to ESL monotherapy during follow-up.

[Nutritional support in chylothorax secondary to lymphoma]. / Soporte nutricional en el quilotórax secundario a linfoma.

Chylothorax is a well-known, albeit infrequent, complication in certain neoplasias including lymphomas. The continuing loss of chyle leads to a profound deterioration in patients' nutritional and immunological status, prevented only by appropriate early nutritional support. There is currently some dispute over its handling, particularly with regard to the most appropriate type of nutritional support and the suitability of conservative treatment versus surgery. The present paper describes the case of a 41-year-old patient diagnosed as having secondary chylothorax following B-cell lymphoma where mixed nutritional support (fat-free enteral nutrition by mouth and total parenteral nutrition) was given, followed by talc pleurodesis, with optimal results. There is a review of the literature and a discussion of the most controversial aspects of its management.

[Pramipexol: a new dopaminergic agonist for the treatment of Parkinson disease]. / Pramipexol: un nuevo agonista dopaminérgico para el tratamiento de la enfermedad de Parkinson.

Pramipexol is a novel nonergot dopamine agonist which has high selectivity for intereacting with dopamine D2 receptors (especially with D3 receptor subtype). It has been effective in early Parkinson's disease as monotherapy and as adjunctive therapy with L-dopa in advanced stages of the disease. Clinical improvement can be observed after 3 or 4 weeks of treatment. The adverse events profile of pramipexol is similar, in general, to that of other dopamine receptor agonists, although it can be foreseen that pramipexol should not induce side effects related to the ergot chemical structure such as eritromelalgia, distal vasospasm, retroperitoneal fibrosis or pleural effusions. Nevertheless, the potential advantages of this promising dopamine agonist should be tested in well-designed prospective comparative studies with other available ergot and nonergot dopamine agonists.

Risk factors for levodopa-induced dyskinesias in Parkinson's disease.

To identify putative risk factors for levodopa-induced dyskinesias we studied the effect of several clinical variables on the occurrence of dyskinesias in a series of 168 consecutive patients with Parkinson's disease treated for at least 6 months with levodopa. Of these, 108 (64%) developed dyskinesias after a mean duration of levodopa treatment of 51.4 +/- 43.3 months. Patients tended to suffer dyskinesias on the side of the body first affected by Parkinson's disease. The overall probability of developing dyskinesias increased with levodopa treatment duration, about 10% per year during the first 7 years. Univariate and multivariate logistic regression analysis identified the age at onset of Parkinson's disease (OR 0.923; 95% CI 0.883-0.964) and the initial levodopa dose (mean dose of the first 6 months of treatment; OR 1.004; 95% CI 1.002-1.006) as the main independent predictors. Survival curves showed that onset of Parkinson's disease at age 50 years or before (logrank, P < 0.05) and initial levodopa treatment with more than 600 mg/day (logrank, P < 0.05) were associated with a higher risk for the appearance of dyskinesias.
