RESUMO
INTRODUCTION: Alemtuzumab is a highly effective drug approved by the European Medicines Agency as a disease-modifying drug for the treatment of relapsing-remitting multiple sclerosis. OBJECTIVE: A consensus document was drafted on the management of alemtuzumab in routine clinical practice in Spain. DEVELOPMENT: A group of multiple sclerosis specialists reviewed articles addressing treatment with alemtuzumab in patients with multiple sclerosis and published before December 2017. The included studies assessed the drug's efficacy, effectiveness, and safety; screening for infections and vaccination; and administration and monitoring aspects. The initial proposed recommendations were developed by a coordinating group and based on the available evidence and their clinical experience. The consensus process was carried out in 2 stages, with the initial threshold percentage for group agreement established at 80%. The final document with all the recommendations agreed by the working group was submitted for external review and the comments received were considered by the coordinating group. CONCLUSION: The present document is intended to be used as a tool for optimising the management of alemtuzumab in routine clinical practice.

RESUMO
INTRODUCTION: Progressive neuronal and axonal loss are considered the main causes of disability in patients with multiple sclerosis (MS). The disease frequently involves the visual system; the accessibility of the system for several functional and structural tests has made it a model for the in vivo study of MS pathogenesis. Orbital ultrasound is a non-invasive technique that enables various structures of the orbit, including the optic nerve, to be evaluated in real time. MATERIAL AND METHODS: We conducted an observational, ambispective study of MS patients. Disease progression data were collected. Orbital ultrasound was performed on all patients, with power set according to the 'as low as reasonably achievable' (ALARA) principle. Optical coherence tomography (OCT) data were also collected for those patients who underwent the procedure. Statistical analysis was conducted using SPSS version 22.0. RESULTS: Disease progression was significantly correlated with ultrasound findings (P=.041 for the right eye and P=.037 for the left eye) and with Expanded Disability Status Scale (EDSS) score at the end of the follow-up period (P=.07 for the right eye and P=.043 for the left eye). No statistically significant differences were found with relation to relapses or other clinical variables. DISCUSSION: Ultrasound measurement of optic nerve diameter constitutes a useful, predictive factor for the evaluation of patients with MS. Smaller diameters are associated with poor clinical progression and greater disability (measured by EDSS).

Introducción: Alemtuzumab es un fármaco de alta eficacia aprobado por la Agencia Europea de Medicamentos como tratamiento modificador de la enfermedad en pacientes con esclerosis múltiple remitente recurrente.ObjetivoElaborar un documento de consenso sobre el manejo de alemtuzumab en la práctica clínica habitual, que sea de aplicación en el ámbito español.DesarrolloUn grupo de expertos en esclerosis múltiple revisó las publicaciones disponibles hasta diciembre de 2017, de tratamiento con alemtuzumab y esclerosis múltiple. Se incluyeron trabajos sobre eficacia, efectividad y seguridad, despistaje de infecciones y vacunación, administración y monitorización. La propuesta inicial de recomendaciones fue desarrollada por un grupo coordinador con base en la evidencia disponible y en su experiencia clínica. El proceso de consenso se llevó a cabo en 2 etapas; se estableció como porcentaje inicial de acuerdo grupal el 80%. El documento final con todas las recomendaciones acordadas por el grupo de trabajo se sometió a revisión externa y los comentarios recibidos fueron considerados por el grupo coordinador.ConclusionesEl documento aportado pretende ser una herramienta útil para facilitar el manejo del fármaco en condiciones de práctica clínica habitual.

Introducción: La pérdida neuronal/axonal progresiva se considera la causa más importante de discapacidad neurológica en la esclerosis múltiple (EM). El sistema visual está frecuentemente afectado en esta enfermedad y su accesibilidad a test funcionales y estructurales ha permitido que se convierta en un modelo para estudiar in vivo la patogenia de la EM. La ecografía orbitaria permite evaluar, de forma no invasiva y en tiempo real, las diversas estructuras de la órbita, incluido el nervio óptico.Material y métodosSe ha llevado a cabo un estudio observacional ambispectivo en pacientes con EM recogiéndose datos evolutivos de la enfermedad. La ecografía orbitaria se realizó en todos los pacientes según el principio de mínima potencia necesaria (ALARA). También se recogieron los datos de tomografía de coherencia óptica (OCT) en aquellos que tenían realizadas ambas pruebas. El estudio estadístico se efectuó con el programa SPSS 22.0.ResultadosSe encontraron correlaciones estadísticamente significativas entre las medidas ecográficas y la progresión de la enfermedad (p = 0,041 para el ojo derecho y p = 0,037 para el ojo izquierdo), y la Expanded Disability Status Scale (EDSS) final en el seguimiento (p = 0,07 para el ojo derecho y p = 0,043 para el ojo izquierdo). No fue así para los datos referentes a brotes y a otras variables clínicas.DiscusiónLa medición del diámetro del nervio óptico por ecografía podría utilizarse como medida predictiva en la evolución de la EM, ya que la disminución del mismo se asocia con progresión clínica y mayor discapacidad, medidas con la EDSS.
