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.

[Pilot study of a new tool to optimise dopaminergic treatment in Parkinson's disease: the OPTIMIPARK questionnaire]. / Estudio piloto de una nueva herramienta para optimizar el tratamiento dopaminérgico en la enfermedad de Parkinson: el cuestionario OPTIMIPARK.

INTRODUCTION: Dopaminergic therapy is effective in Parkinson's disease (PD), but should be adjusted as neurodegeneration progresses. AIMS: The aim of this study was to develop a questionnaire (OPTIMIPARK) to assess the patient's dopaminergic status and assist the clinician in adjusting treatment. PATIENTS AND METHODS: The preliminary, self-administered version of OPTIMIPARK includes nine items that take into account motor and non-motor complications as well as disability. Each item is given a score between 0 and 2, and an overall score from 0 to 18 is obtained. Thirty patients completed the OPTIMIPARK questionnaire and an ad hoc questionnaire about it in a single-centre, observational pilot study. Feasibility, acceptability and preliminary agreement with clinical criteria were analysed. RESULTS: Thirty patients with PD (68.5 ± 7.5 years; range: 43-80 years) in Hoehn and Yahr stage I-III completed OPTIMIPARK (mean total score: 6.7 ± 4; range: 0-14) and the ad hoc questionnaire. Clinical decisions were classified as: 'no change', 'adjustments to conventional treatment' and 'surgical or continuous infusion therapy'. The total OPTIMIPARK scores (mean ± standard deviation) for each option were: 1.4 ± 1 (range: 0-3); 7 ± 2.8 (range: 2-11); and 10.8 ± 1.8 (range: 9-14). The 3/4 cut-off point classified 95.5% of patients as 'no change' versus 'adjustment to conventional treatment', and the 9/10 cut-off point discriminated 78.3% of patients from 'adjustment to conventional treatment' versus 'surgical or continuous infusion therapy', with a concordance (kappa and Lin coefficients) of 0.81. CONCLUSIONS: Although still pending a validation study, OPTIMIPARK may be a viable and useful questionnaire for clinical decision-making in the therapeutic adjustment of PD patients and the identification of candidates for advanced therapies.

TITLE: Estudio piloto de una nueva herramienta para optimizar el tratamiento dopaminérgico en la enfermedad de Parkinson: el cuestionario OPTIMIPARK.Introducción. La terapia dopaminérgica es eficaz en la enfermedad de Parkinson (EP), si bien debe ajustarse conforme progresa la neurodegeneración. Objetivos. Desarrollar un cuestionario (OPTIMIPARK) para valorar el estado dopaminérgico del paciente y ayudar al clínico en el ajuste del tratamiento. Pacientes y métodos. La versión preliminar, autoadministrada, de OPTIMIPARK incluye nueve ítems que tienen en cuenta complicaciones motoras y no motoras, así como la discapacidad. Cada ítem se valora de 0 a 2, y se obtiene una puntuación global de 0 a 18. Treinta pacientes contestaron el cuestionario OPTIMIPARK y un cuestionario ad hoc sobre éste en un estudio piloto unicéntrico y observacional. Se analizaron la viabilidad, la aceptabilidad y la concordancia preliminar con los criterios clínicos. Resultados. Treinta pacientes con EP (68,5 ± 7,5 años; rango: 43-80 años) en estadio de Hoehn and Yahr I-III completaron el OPTIMIPARK (media de la puntuación total: 6,7 ± 4; rango: 0-14) y el cuestionario ad hoc. Las decisiones clínicas se clasificaron como: 'sin cambios', 'ajustes en el tratamiento convencional' y 'terapia quirúrgica o de infusión continua'. Las puntuaciones totales de OPTIMIPARK (media ± desviación estándar) para cada opción fueron: 1,4 ± 1 (rango: 0-3); 7 ± 2,8 (rango: 2-11); y 10,8 ± 1,8 (rango: 9-14). El punto de corte 3/4 clasificó al 95,5% de los pacientes 'sin cambios' frente a 'ajustes del tratamiento convencional', y el corte 9/10 discriminó al 78,3% de los pacientes de 'ajuste del tratamiento convencional' frente a 'terapia quirúrgica o de infusión continua', con concordancia (coeficientes kappa y Lin) de 0,81. Conclusiones. Pendiente del estudio de validación, OPTIMIPARK puede ser un cuestionario viable y útil para la toma de decisiones clínicas en el ajuste terapéutico de pacientes con EP y la identificación de candidatos para terapias avanzadas.

[Clinical experience in the treatment of motor fluctuations in Parkinson's disease. Delphi consensus of a group of experts in movement disorders]. / Experiencia clínica en el tratamiento de las fluctuaciones motoras en la enfermedad de Parkinson. Consenso Delphi de un grupo de expertos en trastornos del movimiento.

INTRODUCTION: Motor fluctuations are one of the most common complications of Parkinson's disease and their treatment is still a complex matter. Therefore, from the Neurology Movement Disorders Group we present our clinical experience in the treatment of these complications, with the intention of it being useful in decision-making in daily clinical practice. DEVELOPMENT: Nineteen questions were developed based on a literature review and an open survey answered by members of this group. These issues were discussed in two phases, using the Delphi methodology. Considering the results of the survey, levodopa dose adjustment and dopamine agonists are the option with the best efficacy/tolerability ratio in the treatment of motor fluctuations. Rotigotine is useful in the motor fluctuations associated with gastroparesis, and intermittent subcutaneous apomorphine has positive effects in patients with unpredictable off periods. The most relevant adverse effect associated with dopamine agonists is impulse control disorder. Catechol-O-methyltransferase inhibitors are useful in the initial stages of motor fluctuations, especially in wearing off. Monoamine oxidase inhibitors are generally drugs that are well-tolerated and useful in motor fluctuations. If these measures are not effective, second-line treatments should be indicated on a case-by-case basis. CONCLUSION: The clinical profile of patients with Parkinson's disease is paramount in deciding the most appropriate therapy for the treatment of motor fluctuations.

TITLE: Experiencia clínica en el tratamiento de las fluctuaciones motoras en la enfermedad de Parkinson. Consenso Delphi de un grupo de expertos en trastornos del movimiento.Introducción. Las fluctuaciones motoras son una de las complicaciones más frecuentes en la enfermedad de Parkinson y su tratamiento sigue siendo complejo. Por ello, desde el Grupo de Trastornos del Movimiento de la Asociación Madrileña de Neurología presentamos nuestra experiencia clínica en el tratamiento de estas complicaciones, con la intención de que sea de utilidad en la toma de decisiones en la práctica clínica diaria. Desarrollo. Se elaboraron 19 preguntas a partir de una revisión bibliográfica y una encuesta abierta respondida por los miembros de dicho grupo. Dichas cuestiones se debatieron en dos fases, utilizando la metodología Delphi. Considerando los resultados de la encuesta, el ajuste de la dosis de levodopa y los agonistas dopaminérgicos son la opción con mejor relación eficacia/tolerabilidad en el tratamiento de las fluctuaciones motoras. La rotigotina es útil en las fluctuaciones motoras asociadas a gastroparesia, y la apomorfina subcutánea intermitente, en pacientes con off impredecible. El efecto adverso más relevante asociado a los agonistas dopaminérgicos es el trastorno del control de impulsos. Los inhibidores de la catecol-O-metiltransferasa son útiles en las fluctuaciones motoras de inicio, especialmente en el wearing off. Los inhibidores de la monoaminooxidasa son fármacos, en general, bien tolerados y útiles en las fluctuaciones motoras. En caso de que estas medidas no resulten eficaces, se deben indicar terapias de segunda línea de manera individualizada. Conclusión. El perfil clínico del paciente con enfermedad de Parkinson es primordial para decidir la terapia más adecuada en el tratamiento de las fluctuaciones motoras.

[Pharmacoeconomic study of the treatment of advanced Parkinson's disease]. / Estudio farmacoeconomico del tratamiento de la enfermedad de Parkinson avanzada.

INTRODUCTION: When oral or transdermal drug therapy in Parkinson's disease becomes less effective, there are three therapies using assisted devices that can reduce motor and non-motor complications: subcutaneous apomorphine infusion pump (SAIP), continuous levodopa/carbidopa duodenal infusion (LDI) and deep brain stimulation (DBS). AIM: Conduct a comparative pharmacoeconomic analysis of the use of SAIP, with LDI and DBS. As a secondary objective arises discuss the profile of the ideal candidate for each of the technicals. PATIENTS AND METHODS: Information on life years gained and quality adjusted life years (QALY) according to Hoehn and Yahr scale was obtained, as well as data on costs and resource use for each of the alternatives. The perspective of the analysis was the National Health System and the time horizon was 5 years for costs and patient´s lifetime for utilities. Outcome measures used were life years gained and QALYs, and incremental cost/utility ratio for comparison. RESULTS: Cost/utility ratio was obtained for each option: 31,956 euros/QALY for DBS, 38,249 euros/QALY for SAIP, and 75,206 euros/QALY for LDI. CONCLUSIONS: Our results allow us to add information about effectiveness of different treatments, as these are presented in gain of years lived in full health (QALY). Data obtained contribute to decision making that determine planning and management of each case, without forgetting patient and neurologist preferences, as well as budgetary limitations.

[Guide to the comprehensive treatment of spasticity]. / Guia del tratamiento integral de la espasticidad.

AIMS AND DEVELOPMENT: Spasticity is an important medical problem with a high rate of incidence both in childhood, mainly as a result of cerebral palsy, and in adults, which is frequently brought about by traumatic brain injuries, strokes and spinal cord injuries. Spasticity is part of upper motoneuron syndrome, which gives rise to important problems, such as limited joint movement, abnormal postures that can produce pain, impaired functional capacity, aesthetic or hygiene disorders, among others. It progresses naturally towards chronicity, accompanied by static phenomena due to alterations affecting the properties of soft tissues (elasticity, plasticity and viscosity). Numerous therapeutic options are available for the treatment of spasticity, including medication, physiotherapy, orthopaedic aid, surgery, and so forth. Moreover, treatment should be individualised and realistic, with goals that have been agreed between the patient or caregiver and the medical team. The aim of the following guide is to further our knowledge of this condition, its causes, epidemiology and progression, as well as to outline an approach that is both rational and global from the point of view of pharmacological, rehabilitation and surgical treatment. CONCLUSIONS: Spasticity is a complex problem that requires specialists (neurologist, rehabilitation doctor, occupational therapist, orthopaedic surgeon, general practitioner, etc.) to work as a team in order to achieve the goals set out when treatment is begun. Early treatment is important to avoid or reduce, as far as possible, the severe complications stemming from this condition.

Guía del tratamiento integral de la espasticidad / Guide to the comprehensive treatment of spasticity

Objetivos y desarrollo. La espasticidad constituye un problema médico de incidencia y trascendencia elevada tanto en la infancia, como consecuencia principalmente de la parálisis cerebral, como en adultos, ocasionada frecuentemente por traumatismos craneoencefálicos, ictus y lesión medular. La espasticidad forma parte del síndrome de motoneurona superior que ocasiona problemas importantes, como son: limitación articular, posturas anómalas que pueden generar dolor, alteraciónde la capacidad funcional, alteraciones estéticas o de higiene, entre otras. Su evolución natural es hacia la cronicidad, acompañada de fenómenos estáticos por alteraciones de las propiedades de los tejidos blandos (elasticidad, plasticidad y viscosidad).Las opciones terapéuticas de la espasticidad son múltiples: fármacos, fisioterapia, ayudas ortopédicas, cirugía, etc.Además, el tratamiento debe ser individualizado y realista, con unos objetivos consensuados entre el paciente o cuidador y el equipo médico. El objetivo de la siguiente guía es profundizar en el conocimiento de esta patología, sus causas, epidemiologíay evolución, así como aportar una forma racional y global de abordaje desde el punto de vista del tratamiento farmacológico, rehabilitador y quirúrgico. Conclusión. La espasticidad es un problema complejo que requiere un trabajo en equipo(neurólogo, rehabilitador, terapeuta ocupacional, cirujano ortopeda, médico de familia, etc.) para conseguir los objetivos que se fijan al principio de su tratamiento. Es importante el tratamiento precoz para evitar o reducir, en la medida de lo posible, las graves complicaciones que conlleva

[Guidelines for the treatment of child spasticity using botulinum toxin]. / Guía terapéutica de la espasticidad infantil con toxina botulínica.

AIMS: The introduction of botulinum toxin has been a significant step forward in the treatment of spasticity in children and is now considered to be the preferred treatment in focal spasticity. With the aim of optimising this therapeutic resource, a group of Spanish neurologists and specialists in rehabilitation have drawn up these therapeutic guidelines based on the currently available evidence on its use and indications, and on their own experience. DEVELOPMENT: Spasticity in childhood is mainly caused by infantile cerebral palsy. Its natural history is not favourable due to the negative effect of growth and it should be treated before permanent deformities in bones and joints appear. Treatment with botulinum toxin diminishes hyperactivity and muscle tone, and allows the muscle to grow longitudinally, which prevents permanent contractions. The advantages of botulinum toxin are obvious (ease of use and dosing, long-lasting effects, reversibility in case of adverse responses, and so forth) and outnumber by far the few drawbacks it offers. Before it can be used patients, treatment goals and the muscle areas to be treated must all be selected correctly and, at the same time, a tailored rehabilitation scheme must also be developed. The growing body of experience suggests that its early administration is effective in preventing or reducing the severe complications of spasticity. CONCLUSIONS: Botulinum toxin type A is very effective in the treatment of spasticity. These guidelines offer the well-documented experience gained from its use and our knowledge about its indications, effects and safety in clinical practice.

[Ropinirole in the treatment of Parkinson's disease: an update]. / Ropinirol en el tratamiento de la enfermedad de Parkinson: actualización.

INTRODUCTION: Ropinirole is a non-ergot dopaminergic agonist with a high affinity for D2 dopaminergic receptors which improves the symptoms of Parkinson's disease (PD) and delays the appearance of motor complications. It is different to the first generation of dopaminergic agonists in that, because it lacks an ergolinic structure, it does not have the side effects that usually appear with the use of this pharmacological group. DEVELOPMENT: Recent functional neuroimaging studies suggest a possible neuroprotector effect of the drug, although this aspect is still under discussion. The question as to when and how early treatment of PD must be started has been a controversial issue for many years now. Dopaminergic agonists have been used in monotherapy in patients with de novo disease with the intention of deferring treatment with levodopa and, in consequence, postponing the onset of the complications stemming from its use. Ropinirole has been evaluated in different studies both in monotherapy and as adjunctive therapy with levodopa. CONCLUSIONS: In the numerous clinical trials that were carried out, it would seem clear that ropinirole can be administered for years as sole early treatment for PD and that it offers a notable reduction in the appearance of dyskinesias. Given the linear dose-response relation it presents, the drug has a wide "therapeutic window" that allows the dosage to be increased as the disease progresses.

Ropinirol en el tratamiento de la enfermedad de Parkinson: actualización / Ropinirole in the treatment of Parkinson’s disease: an update

Introducción. El ropinirol es un agonista dopaminérgicono ergótico con alta afinidad por los receptores dopaminérgicos D2,que proporciona una mejoría sintomática de la enfermedad de Parkinson(EP) y retrasa la aparición de las complicaciones motoras. Se diferencia de la primera generación de agonistas dopaminérgicos en que, al carecer de estructura ergolínica, no presenta los efectos secundarios que aparecen con este grupo farmacológico. Desarrollo. Recientes estudios con neuroimagen funcional invocan un posible efecto neuroprotector del fármaco, aunque este aspecto es foco de discusión. Desde hace años, la pregunta de cuándo y cómo debe iniciarse el tratamiento de la EP precoz continúa siendo un motivo de controversia. Los agonistas dopaminérgicos se han utilizado en monoterapia en pacientes con enfermedad de novo con la intención de retrasar el tratamiento con levodopa y, consecuentemente, diferir el comienzo de las complicaciones derivadas de su uso. El ropinirol se ha evaluado en diferentes estudios, tanto en monoterapia como en terapia añadida a la levodopa. Conclusiones. En losmúltiples ensayos clínicos realizados, parece constatado que el ropinirol puede administrarse durante años como tratamiento único dela EP precoz y que reduce notablemente la aparición de discinesias. Dada una relación lineal dosis-respuesta, el fármaco dispone de una amplia 'reserva terapéutica' que permite aumentar la dosis a medida que progresa la enfermedad (AU)

[Guidelines for the treatment of spasticity in adults using Botulinum toxin]. / Guía terapéutica de la espasticidad del adulto con toxina botulínica.

AIMS: The introduction of Botulinum toxin type A (BTA) in the treatment of spasticity in adults was a large step forward in neurology and it is currently seen as the first choice treatment in focal spasticity. In an attempt to achieve the optimisation of this therapeutic resource, different clinical guidelines have been drawn up which include reviews of the evidence available about the indications and use of BTA. Spasticity is characterised by the presence of involuntary muscular hyperactivity that is often associated to pain, deformity and functional disability. From the clinical point of view, the advantages of BTA are obvious (ease of use and dosage determination, long lasting effects, reversibility should the response be inappropriate, etc.) and far outweigh its drawbacks. It can only be used after a proper selection of patients, of the therapeutic aims and of the muscular areas to be treated, and a tailor-made programme of rehabilitation must also be drawn up. Increasing experience in its use suggests that its early administration is effective in preventing or reducing the complications arising from spasticity. CONCLUSIONS: BTA is effective in the treatment of spasticity and plays a significant role if the clinical objectives involve functional aspects. At present a large amount of well-documented experience concerning its indications, effects and safety in clinical practice is already available.

Guía terapéutica de la espasticidad del adulto con toxina botulínica / Guidelines for the treatment of spasticity in adults using botulinum toxin

Objetivos. La introducción de la toxina botulínica A (TBA) en el tratamiento de la espasticidad en los adultos supuso un avance significativo en neurología; en la actualidad, se considera el tratamiento de elección en la espasticidad focal. Para conseguir la optimización de este recurso terapéutico, se han elaborado diferentes guías clínicas en las que se revisa la evidencia disponible sobre las indicaciones y el uso de la TBA. La espasticidad se caracteriza por la presencia de hiperactividad muscular involuntaria que, con frecuencia, se asocia a dolor, deformidad y discapacidad funcional. Las ventajas de la TBA son evidentes desde el punto de vista clínico (facilidad de uso y dosificación, larga duración del efecto, reversibilidad en caso de respuesta inadecuada, etc.) y superan ampliamente sus inconvenientes. Para su empleo se requiere una correcta selección de los pacientes, de los objetivos de tratamiento y de las áreas musculares a tratar y, finalmente, el desarrollo de un plan de rehabilitación personalizado. La creciente experiencia en su uso sugiere que su administración precoz es eficaz para evitar o reducir las complicaciones de la espasticidad. Conclusión. La TBA es efectiva en el tratamiento de la espasticidad y desempeña un papel evidente si los objetivos clínicos son funcionales. Actualmente, existe experiencia bien documentada sobre su uso y se conocen sus indicaciones, efectos y seguridad en la práctica clínica (AU)
