Advanced Parkinson's disease: clinical characteristics and treatment. Part II.

INTRODUCTION: Many patients who have had Parkinson's disease (PD) for several years will present severe motor fluctuations and dyskinesias which require more aggressive therapies. The different approaches which are now available include deep brain stimulation of the subthalamic nucleus or medial globus pallidus, subcutaneous infusion of apomorphine, and intestinal infusion of levodopa-carbidopa. OBJECTIVE: To define the indications and results for the 3 available therapies for advanced PD. DEVELOPMENT: Exhaustive review of the literature concerning the indications and results of deep brain stimulation, subcutaneous apomorphine infusion and duodenal infusion of levodopa/carbidopa gel to treat patients with advanced Parkinson disease. CONCLUSIONS: Although numerous studies have confirmed the efficacy of the 3 different therapies in advanced PD, there are no comparative studies that would allow us to define the best candidate for each technique.

[Advanced Parkinson's disease: clinical characteristics and treatment (part 1)]. / Enfermedad de Parkinson avanzada. Características clínicas y tratamiento (parte I).

INTRODUCTION: A large percentage of patients with Parkinson's disease (PD) develop motor fluctuations, dyskinesias, and severe non-motor symptoms within 3 to 5 years of starting dopaminergic therapy, and these motor complications are refractory to treatment. Several authors refer to this stage of the disease as advanced Parkinson's disease. OBJECTIVE: To define the clinical manifestations of advanced PD and the risk factors for reaching this stage of the disease. DEVELOPMENT: This consensus document has been prepared by using an exhaustive literature search and by discussion of the contents by an expert group on movement disorders of the Sociedad Española de Neurología (Spanish Neurology Society), coordinated by two of the authors (JK and MRL). CONCLUSIONS: Severe motor fluctuations and dyskinesias, axial motor symptoms resistant to levodopa, and cognitive decline are the main signs in the clinical phenotype of advanced PD.

Spanish expert consensus on the use of safinamide in Parkinson's disease.

Safinamide is a new add-on drug to levodopa for the treatment of Parkinson's disease (PD) with motor fluctuations. Due to the recent incorporation of safinamide into routine clinical practice, no post-authorisation phase IV studies on the safety of safinamide have been conducted to date. This study provides clinical management guidelines for safinamide based on the opinion of a group of experts in movement disorders. This project was developed in 2 phases: 16 local meetings in phase 1 and a national meeting in phase 2. The meetings followed a pre-established agenda. The present clinical practice guidelines are based on the main conclusions reached during the national meeting. The group concluded that safinamide is effective in reducing motor and non-motor fluctuations. PD patients with mild-to-moderate fluctuations benefit most from treatment, although the drug may also improve the clinical status of patients with advanced PD. The dose of other dopaminergic drugs may be reduced after introducing safinamide, which would contribute to reducing such adverse reactions as impulse control disorder. At doses higher than those usually prescribed, safinamide may also improve dyskinesia. The experts agreed that safinamide is well tolerated and causes few adverse reactions when compared with placebo.

La safinamida es un nuevo fármaco para el tratamiento de pacientes con enfermedad de Parkinson (EP) con fluctuaciones como tratamiento complementario a levodopa. Dado que por el momento aún no existen estudios de fase IV postautorización debido a la reciente incorporación de la safinamida a la práctica clínica habitual, el interés de este proyecto radica en el desarrollo de una guía de manejo clínico de la safinamida basada en las opiniones de expertos de trastornos del movimiento. Este proyecto se desarrolló en 2 fases: una primera fase que constó de 16 reuniones locales y una segunda fase que consistió en una reunión nacional. Dichas reuniones siguieron un guion de trabajo preestablecido. Tras la reunión nacional se recopilaron las principales conclusiones de los expertos, que han supuesto la base para redactar la presente guía clínica. Se concluyó que la safinamida es eficaz en la reducción de las fluctuaciones motoras y no motoras. Los pacientes con EP con fluctuaciones leves-moderadas son los que más se benefician del tratamiento, si bien el fármaco puede contribuir a mejorar diversos problemas clínicos en pacientes con EP avanzada. Se ha destacado la posibilidad de reducir la dosis de otros fármacos dopaminérgicos tras la introducción de la safinamida, lo cual contribuiría a reducir efectos adversos como el trastorno de control de impulsos. Se hipotetizó sobre el posible efecto de la safinamida sobre la mejoría de las discinesias a dosis más altas de las habitualmente utilizadas. Se ha consensuado que la safinamida es bien tolerada y presenta un perfil de efectos adversos favorable frente a placebo. (AU)

Enfermedad de Parkinson avanzada. Características clínicas y tratamiento. Parte I I / Advanced Parkinson's disease: Clinical characteristics and treatment. Part II

Introducción. Muchos de los pacientes con enfermedad de Parkinson (EP) presentan al cabo de varios años fluctuaciones y discinesias graves que requieren de terapias algo más agresivas como la estimulación cerebral profunda del núcleo subtalámico o globo pálido medial, la infusión continua de apomorfina y la infusión intestinal continua de levodopa-carbidopa. Objetivo: Establecer las indicaciones y resultados de las 3 técnicas disponibles en la actualidad para el tratamiento de la EP avanzada. Desarrollo: Revisión exhaustiva de los datos publicados en la literatura sobre las indicaciones y resultados de la estimulación cerebral profunda del núcleo subtalámico, infusión subcutánea de apomorfina e infusión intestinal continua de levodopa-carbidopa en pacientes con EP avanzada. Conclusiones: Aunque existen numerosos estudios que han descrito la eficacia de cada una de estas 3 técnicas, faltan estudios comparativos que permitan definir el candidato ideal para cada una de las técnicas (AU)

Enfermedad de Parkinson avanzada. Características clínicas y tratamiento (parte I) / Advanced Parkinson’s disease: Clinical characteristics and treatment (part 1)

Introducción: Un porcentaje importante de pacientes con enfermedad de Parkinson (EP) desarrollan complicaciones motoras en forma de fluctuaciones motoras, discinesias y síntomas no motores al cabo de 3-5 años del inicio del tratamiento que resultan de difícil control terapéutico. Esta fase de la enfermedad ha sido definida por algunos autores como fase avanzada de la EP. Objetivo: Definir las características clínicas y los factores de riesgo que condicionan que una EP evolucione a un estadio avanzado. Desarrollo: Este documento de consenso se ha realizado mediante una búsqueda bibliográfica exhaustiva y discusión de los contenidos llevadas a cabo por un grupo de expertos en trastornos del movimiento de la Sociedad Española de Neurología coordinados por dos de los autores (JK y MRL). Conclusiones: La presencia de fluctuaciones motoras y discinesias graves, síntomas motores axiales resistentes a la levodopa y síntomas no motores, como los trastornos cognitivos, representan las principales manifestaciones fenotípicas de una EP Avanzada (AU)
