Consensus statement on the use of alemtuzumab in daily clinical practice in Spain.

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.

Review of the novelties presented at the 29th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (I).

The most relevant data presented at the 29th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), held in October 2013 in Denmark, were summarised at the sixth edition of the Post-ECTRIMS Expert Meeting, held in Madrid in October 2013, resulting in this review, to be published in three parts. This first part of the Post-ECTRIMS review presents an update on gender differences in multiple sclerosis (MS) as well as new evidence on the impact of sex hormones on the disease. We should consider that there is still much to discover with regard to the genetic components of the disease. Similarly, possible infections and lifestyle habits are added as triggers of the known environmental risk factors for MS. The interaction between genetics and the environment has been increasingly implicated as a cause of susceptibility to MS. With regard to the mechanisms of inflammation, axo-glial proteins, instead of myelin proteins, may be the early antigenic targets, and B cells have been implicated in the production of cytokines toxic to oligodendrocytes. Chitinase 3-like 1 (CHI3L1) is validated as a prognostic marker of conversion to MS, and immunoglobulin M oligoclonal bands and L-selectin could be incorporated as possible measures of the risk stratification strategy in patients treated with natalizumab.

TITLE: Revision de las novedades presentadas en el XXIX Congreso del Comite Europeo para el Tratamiento e Investigacion en Esclerosis Multiple (ECTRIMS) (I).Los datos mas relevantes presentados en la XXIX edicion del Congreso del Comite Europeo para el Tratamiento e Investigacion en Esclerosis Multiple (ECTRIMS), celebrado en octubre de 2013 en Dinamarca, se han resumido en la sexta edicion de la Reunion de Expertos Post-ECTRIMS celebrada en Madrid en octubre de 2013, fruto de la cual nace esta revision, que se publica en tres partes. Esta primera parte de la revision Post-ECTRIMS presenta una vision actualizada de las diferencias de genero en la esclerosis multiple (EM), asi como las nuevas evidencias sobre el impacto de las hormonas sexuales en la enfermedad. Podemos asumir que aun queda mucho por descubrir con relacion al componente genetico de la enfermedad. De la misma manera, a los ya conocidos factores ambientales de riesgo para la EM se unen posibles infecciones y habitos de vida como desencadenantes. La interaccion entre la genetica y el ambiente cada vez cobra mas fuerza como causa de susceptibilidad a la EM. En cuanto a los mecanismos de inflamacion, las proteinas del complejo axoglial pueden ser las dianas antigenicas iniciales en lugar de las proteinas de mielina, y las celulas B se han visto implicadas en la produccion de citocinas toxicas para los oligodendrocitos. La quitinasa 3-like 1 se valida como marcador pronostico de conversion a EM, y las bandas oligoclonales de inmunoglobulina M y la L-selectina podrian incorporarse como posibles medidas dentro de la estrategia de estratificacion del riesgo en pacientes tratados con natalizumab.

Review of the novelties presented at the 28th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (II).

The most relevant data presented at the 28th edition of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) held in October 2012 in France have been summarised in the fifth edition of the Post-ECTRIMS Expert Meeting held in Madrid in October 2012. This review is the result of the meeting, which is being published in three parts. This second part of the Post-ECTRIMS review discusses the biology of recovery and remyelination in multiple sclerosis (MS) as well as the different repair and endogenous and exogenous remyelination strategies currently being evaluated based on the fact that resident microglia and oligodendroglial progenitor cells have been implicated in the remyelination process. This review also discusses the current state and future use of biomarkers in MS and proposes as markers of neurodegeneration the following: T2 lesion volume and brain atrophy using MRI and the loss of the ganglion cell layer as assessed by optical coherence tomography. A greater future utility for double inversion recovery (DIR) sequences is proposed to correlate cognitive impairment with MS impairment, given its higher diagnostic yield in locating and defining cortical lesions. The availability of novel biomarkers in the future requires strict validation. In this context, this paper proposes possible areas of action to improve the current situation and also presents the latest research results in identifying potential candidates with useful diagnostic characteristics, prognostic characteristics, treatment responses, and safety procedures.

En esta segunda parte de la revision Post-ECTRIMS se analiza la biologia de la recuperacion y remielinizacion en la esclerosis multiple (EM), y se discuten las diferentes estrategias de reparacion y remielinizacion endogena y exogena que actualmente estan siendo evaluadas, sobre la base de que la microglia residente y las celulas precursoras de oligodendrocitos se han visto implicadas en el proceso de remielinizacion. Asimismo, se expone el estado actual y uso futuro de los biomarcadores en EM, y se proponen como marcadores de neurodegeneracion el volumen lesional en T2 y la atrofia cerebral mediante resonancia magnetica, asi como la perdida de capa de celulas ganglionares mediante tomografia de coherencia optica. Se plantea una mayor utilidad futura de las secuencias DIR para correlacionar las alteraciones cognitivas con las alteraciones de la EM, dado su mayor rendimiento diagnostico en localizar y definir lesiones corticales. La disponibilidad de nuevos biomarcadores en un futuro requiere una validacion estricta. En este sentido, se plantean posibles areas de actuacion dirigidas a mejorar la situacion actual, y ademas se presentan los resultados de las investigaciones mas recientes en la identificacion de posibles candidatos con utilidad diagnostica, pronostica, de respuesta al tratamiento y de seguridad.

Estudio observacional multicéntrico español de primeros episodios sugestivos de esclerosis múltiple: cohorte PREM / Spanish multi-centre observational study of the fi rst attacks suggestive of multiple sclerosis: the PREM cohort

Introducción. Estudios recientes han demostrado la necesidad de optimizar el manejo de los pacientes tras un primer brote sugerente de esclerosis múltiple (EM). Nuestro objetivo es comprobar si los resultados de seguimiento de estos estudios son reproducibles en un contexto multicéntrico español. Pacientes y métodos. El estudio PREM (estudio multicéntrico español prospectivo observacional a 24 meses) incluyó a pacientes en los tres primeros meses tras un primer brote sugerente de EM con al menos dos lesiones típicas en una resonancia magnética. Se obtuvo la Expanded Disability Status Scale (EDSS) y se valoró la presencia de brotes basalmente y a los 3, 6, 9, 12, 18 y 24 meses; se realizó una resonancia magnética basalmente y a los 6 y 24 meses, para el cálculo del volumen cerebral y de volúmenes lesionales (T1, T2 y T1 tras la administración de gadolinio). Se valoraron los criterios de McDonald y Poser durante el seguimiento. Un subgrupo de pacientes fue seguido hasta completar cuatro años. Resultados. Se incluyó a 110 pacientes (un 67% mujeres) de edad media de 30,2 años; 22 pacientes abandonaron prematuramente el estudio. Un 19% y un 45% de pacientes cumplían criterios de Poser a los 6 meses y 24 meses, respectivamente; un 63% y un 71% en el caso de los criterios de McDonald. La EDSS descendió signifi cativamente (–0,94; p < 0,001) y se observó desarrollo de atrofi a (–1,2%; p < 0,001) a los 24 meses. Conclusión. Los resultados de seguimiento de pacientes con primeros brotes sugerentes de EM en un contexto multicéntrico español son superponibles a los de los ensayos clínicos internacionales realizados en estos pacientes (AU)

Introduction. Recent studies have shown the need to optimise the management of patients after a fi rst attack suggestive of multiple sclerosis (MS). Our aim is to determine whether the results from follow-ups in these studies are reproducible within a Spanish multi-centre context. Patients and methods. The PREM study (observational prospective Spanish multi-centre study at 24 months) included patients in the fi rst three months following a fi rst event suggestive of MS with at least two typical lesions in a magnetic resonance scan. The Expanded Disability Status Scale (EDSS) was obtained and the presence of attacks was evaluated basally and at 3, 6, 9, 12, 18 and 24 months; a magnetic resonance scan was performed basally and at 6 and 24 months so as to be able to calculate the brain volume and the volumes of the lesions (T1, T2 and T1 after administering gadolinium). McDonald and Poser criteria were evaluated during the follow-up. A subgroup of patients was followed up for a total eriod of four years. Results. Altogether 110 patients (67% females) with a mean age of 30.2 years were included in the study; 22 patients dropped out of the study before it fi nished. Poser criteria were met by 19% and 45% of patients at 6 months and 24 months, respectively; 63% and 71% satisfi ed McDonald criteria. The EDSS decreased signifi cantly (–0.94; p < 0.001) and development of atrophy was observed (–1.2%; p < 0.001) at 24 months. Conclusions. Results of the follow-up of patients with fi rst attacks suggestive of MS within a Spanish multi-centre context are wholly comparable with those from international clinical trials performed in these patients (AU)

El diagnóstico precoz de esclerosis múltiple en urgencias: una necesidad con importantes implicaciones terapéuticas / Early diagnosis of multiple sclerosis in the emergency department: necessary for its important therapeutic implications

Numerosos estudios internacionales han concluido que los pacientes que inician el tratamiento para la esclerosis múltiple (EM) en las fases tempranas de la enfermedad experimentan una notable reducción en el número e intensidad de los brotes y, como consecuencia, tienen mayor probabilidad de permanecer durante más tiempo activos e independientes. Así pues, podemos afirmar que la detección precoz de la EM puede resultar el método más efectivo para combatir esta enfermedad degenerativa, que actualmente afecta en España a unas 40.000 personas. La primera fuente de diagnóstico de estos pacientes es el servicio de urgencias de los hospitales y representa casi un tercio de los diagnosticados de EM. En este contexto, los urgenciólogos cobran especial relevancia y deben ser capaces de sospechar que un paciente sin clínica previa neurológica puede presentar un primer brote de EM. En esta revisión se muestran las claves para poder detectar a estos enfermos lo antes posible, para evitar así demoras que puedan causar una pérdida de los efectos beneficiosos de los tratamientos actualmente disponibles (AU)

Numerous international studies have shown that patients who start treatment for multiple sclerosis (MS) early havemarkedly fewer outbreaks and the episodes are less intense. Consequently, they are likely to stay active and independentlonger. We might say that early detection of MS is the most effective way to fight this degenerative disease, which presently affects some 40 000 persons in Spain. Hospital emergency departments are often the first place MS is recognized, and nearly a third of all MS diagnoses are made there. Emergency physicians therefore play an importantrole and should be able to suspect the debut of this disease in patients without a prior history of neurological symptoms. This review discusses the keys for identifying MS as early as possible to avoid delays that may diminish the effectiveness of currently available treatments (AU)

[Review of the novelties presented at the 26th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) (II)]. / Revision de las novedades presentadas en el XXVI Congreso del Comite Europeo para el Tratamiento e Investigacion en Esclerosis Multiple (ECTRIMS) (II).

The new insights presented at European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), held in the city of Gothenburg, Sweden, in October 2010, have been summarized at the third edition of Post-ECTRIMS meeting held in Madrid in November 2010. Encouraging findings from the 5-years follow up extension from PreCISe study confirm the benefit of early treatment with glatiramer acetate in patients with clinically isolated syndromes (CIS) against the conversion to clinically definitive multiple sclerosis and cerebral atrophy with an adequate safety and tolerability. Regarding treatment decision with escalation or induction therapy, different strategies have been proposed depending on to the characteristics of the individual patient with CIS. Findings from several of the reported studies have revealed the favorable role of combined therapy on relapse rate but not on magnetic resonance parameters in patients with recurrent-remittent multiple sclerosis. Novel therapies such as alemtuzumab, daclizumab ofatutumab or ocrelizumab have shown promising findings regarding efficacy. Nevertheless, safety findings for these emerging therapies have detected some severe adverse events, the main ones being potentially fatal opportunistic infections such as progressive multifocal leukoencephalopathy (PML) caused by JC virus, mainly linked to natalizumab treatment. In this regard, clinicians will face the assessment of he benefit-risk ratio when deciding on the adequate treatment for each patient in the clinical setting. In this regard, determination of antibodies to JC virus by a novel two-step enzyme-linked immunosorbent assay (ELISA) could provide clinicians with a useful tool to stratify PML risk in patients. Regarding non pharmacologic therapies, behavioral intervention has emerged as an effective therapy in the treatment of depression in multiple sclerosis, showing additional benefits on fatigue, disability and adherence to treatment.
