Consensus statement of the Spanish Society of Neurology on the treatment of multiple sclerosis and holistic patient management in 2023.

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.

¿Rombencefalomielitis aguda recurrente del adulto o neuromielitis óptica? A propósito de un caso / Recurrent acute rhombencephalomyelitis in an adult or neuromyelitis optica? Presentation of a case

Introducción: La falta de criterios homogéneos aceptados para la definición de algunas de las patologías desmielinizantes dificulta la caracterización diagnóstica limitando la reproducibilidad de los resultados y las recomendaciones terapéuticas. Especialmente controvertidas son las formas de encefalomielitis recurrentes (EAD-RR) y otras formas infrecuentes de neuromielitis óptica (NMO).Objetivo: Describimos la evolución clínico-radiológica de un caso de EAD-RR del adulto versus NMO, seguida durante 9 años. Paciente y métodos: La paciente debutó con síntomas severos de rombencefalomielitis y la resonancia magnética (RM) craneal y medular mostraron lesiones extensas, con captación de gadolinio en el tronco encefálico y de la médula, acorde con los síntomas clínicos de la paciente. Se excluyó etiología infecciosa, el índice IgG fue normal y fueron negativos los anticuerpos para NMO. Tras tratamiento con corticoides por vía intravenosa y plasmaféresis la recuperación del episodio fue excelente. Durante el seguimiento ha presentado 7 recurrencias, preferentemente medulares, con buena recuperación, que reproducen con severidad variable los mismos síntomas. Desde el inicio ha recibido tratamiento inmunosupresor. Conclusiones: Nuestro caso comparte características clínicas con EAD-RR y NMO e ilustra que, pese a los criterios vigentes, la caracterización diagnóstica de estas entidades no es fácil (AU)

Introduction: The lack of accepted homogeneous criteria for the definition of some demyelinating diseases makes diagnostic characterization difficult and limits data interpretation and therapeutic recommendations. Recurrent encephalomyelitis (ADE-R) along with borderline cases of neuromyelitis optica (NMO) are especially controversial. Objective:To describe the clinical and radiological evolution of an adult-onset ADE-R versus NMO case throughout 9 years of follow-up. Patient and methods: Our patient presented with severe symptoms of rhombencephalomyelitis and the cranial and spinal magnetic resonance imaging (MRI) showed large lesions, with gadolinium enhancement in brainstem and spinal cord, correlating with the clinical picture. Infectious aetiology was excluded, IgG index was normal and NMO antibodies were negative. After treatment with intravenous corticosteroids and plasmapheresis, there was excellent recovery in the acute phase. During follow-up, seven relapses have occurred, mainly in the spinal cord, with good recovery and the same symptomatology, albeit with different severity. Immunosuppressive treatment was introduced since the beginning.Conclusions: Our case shares common features of both ADE-R and NMO, illustrating that diagnostic characterization is not easy in spite of current criteria (AU)
