The last consensus statement of the Spanish Society of Neurology’s Demyelinating Diseases Study Group on the treatment of multiple sclerosis (MS) was issued in 2016. Although many of the positions taken remain valid, there have been significant changes in the management and treatment of MS, both due to the approval of new drugs with different action mechanisms and due to the evolution of previously fixed concepts. This has enabled new approaches to specific situations such as pregnancy and vaccination, and the inclusion of new variables in clinical decision-making, such as the early use of high-efficacy disease-modifying therapies (DMT), consideration of the patient’s perspective, and the use of such novel technologies as remote monitoring.In the light of these changes, this updated consensus statement, developed according to the Delphi method, seeks to reflect the new paradigm in the management of patients with MS, based on the available scientific evidence and the clinical expertise of the participants.The most significant recommendations are that immunomodulatory DMT be started in patients with radiologically isolated syndrome with persistent radiological activity, that patient perspectives be considered, and that the term “lines of therapy” no longer be used in the classification of DMTs (> 90% consensus). Following diagnosis of MS, the first DMT should be selected according to the presence/absence of factors of poor prognosis (whether epidemiological, clinical, radiological, or biomarkers) for the occurrence of new relapses or progression of disability; high-efficacy DMTs may be considered from disease onset. Resumen: El último documento de consenso del Grupo de Estudio de Enfermedades Desmielinizantes de la Sociedad Española de Neurología sobre el tratamiento de la esclerosis múltiple (EM) data del año 2016. Aunque muchas consideraciones continúan todavía vigentes, desde entonces se han producido significativos cambios en el manejo y tratamiento de esta enfermedad motivados no sólo por la aprobación de nuevos fármacos con diferentes mecanismos de acción, sino también por la evolución de conceptos otrora consolidados. Esto ha permitido abordar situaciones especiales como el embarazo y la vacunación desde otra perspectiva e incluir nuevas variables en la toma de decisiones en práctica clínica, como plantear tratamiento modificador de la enfermedad (TME) de alta eficacia en fases tempranas, considerar la perspectiva del paciente y utilizar nuevas tecnologías como monitorización remota.Estos cambios han motivado la presente actualización del consenso mediante metodología Delphi, con el objetivo de reflejar el nuevo paradigma de manejo del paciente con EM basándose en la evidencia científica y experiencia clínica de los participantes.Entre las principales conclusiones destacan como recomendaciones: iniciar TME inmunomodulador en el síndrome radiológico aislado con actividad radiológica persistente, evaluar la perspectiva del paciente y abandonar la terminología “líneas de tratamiento” en la clasificación de los TME (consenso mayor del 90%). Tras el diagnóstico de EM, la elección del primer TME debería considerar la presencia/ausencia de factores de mal pronóstico (epidemiológicos, clínicos, radiológicos y biomarcadores) para la aparición de nuevos brotes o progresión de discapacidad, pudiendo plantear desde el inicio TME de alta eficacia.

Introduction: Neuromyelitis optica spectrum disorders (NMOSD) are immune-mediated inflammatory disorders of the central nervous system involving astrocytes, B lymphocytes, anti-aquaporin 4, and such inflammatory mediators as interleukin-6. Several immunosuppressants are used in their treatment. Tocilizumab, an interleukin-6 receptor antagonist, may be a treatment option. Method: We performed an observational, retrospective study analysing parameters of effectiveness (annualised relapse rate, disability, and radiological progression) and safety of tocilizumab in patients with NMOSD in whom previous immunosuppressant treatment had failed. We aimed to evaluate the effectiveness and safety of tocilizumab in clinical practice in patients with NMOSD not responding to other immunosuppressants. Results: Five patients with NMOSD were analysed. Sixty percent of patients were women; mean age at diagnosis was 50 ± 5.3 years and mean progression time was 4.5 ± 3.6 years. Previously administered immunosuppressants were rituximab (in all 5), cyclophosphamide (2), and azathioprine (1). Mean time of exposure to tocilizumab was 2.3 ± 1 years. Mean annualised relapse rate was 1.8 ± 1.3 in the year prior to the introduction of tocilizumab and 0.2 ± 0.4 the year after (P
