RESUMO

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 cambios significativos en el manejo y tratamiento de esta enfermedad, motivados no solo 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 la 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.

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.

RESUMO

Introducción: La esclerosis múltiple es una enfermedad neurológica crónica con numerosos tratamientos modificadores de la enfermedad disponibles, incluido el dimetilfumarato (DMF), una terapia de primera línea para la esclerosis múltiple remitente-recurrente. Aunque las tasas de discontinuación del DMF suelen ser bajas en los ensayos clínicos, la falta de adhesión al tratamiento se asocia con peores resultados clínicos. Evaluar la adhesión en el mundo real y los factores predictivos es fundamental para mejorar los resultados clínicos de los pacientes. Este estudio evaluó la adhesión al DMF durante 24 meses en una cohorte de pacientes tratados en un centro portugués. Pacientes y métodos: Estudio prospectivo no intervencionista, de un solo centro, con un seguimiento de 24 meses. El estudio incluyó a pacientes adultos con esclerosis múltiple remitente-recurrente tratados con DMF en la práctica clínica habitual. Se calculó la adhesión al DMF y se consideró que los pacientes eran adherentes si el valor estaba por encima del 80%. Se compararon variables clínicas y sociodemográficas entre grupos. Resultados: De los 80 pacientes incluidos, el 74% eran mujeres, con una edad media de 39 años y una edad media en el momento del diagnóstico de 32 años. Veintiséis pacientes no habían recibido tratamiento previo. La adhesión varió entre el 93, el 82 y el 87,5% a los 6, 12 y 24 meses, respectivamente. No se encontraron diferencias entre los pacientes que no habían recibido tratamiento previo y los que sí lo habían recibido. Conclusión: Este análisis en el mundo real mostró una adhesión significativa al tratamiento con DMF durante dos años por parte de los pacientes portugueses. No obstante, estos resultados deben interpretarse considerando los cambios sustanciales en las consultas externas y las diversas restricciones periódicas debidas a la pandemia de COVID-19, que afectaron en gran medida al seguimiento de los pacientes y a la recopilación de datos.(AU)


Introduction: Multiple sclerosis is a chronic neurological disease with numerous disease-modifying treatments available, including dimethyl fumarate (DMF), a first-line therapy for relapsing-remitting multiple sclerosis. Although rates of discontinuation of DMF are generally low in clinical trials, non-adherence to treatment is associated with poorer clinical outcomes. Assessing real-world adherence and predictive factors is critical to be able to improve clinical outcomes for patients. This study evaluated adherence to DMF over 24 months in a cohort of patients treated in a Portuguese healthcare centre. Patients and methods: A prospective, non-interventional, single-centre study with 24 months’ follow-up was conducted. The study included adult patients with relapsing-remitting multiple sclerosis treated with DMF in routine clinical practice. Adherence to DMF was calculated and patients were considered to have adhered if the value was above 80%. Clinical and socio-demographic variables were compared between groups. Results: Of the 80 patients included, 74% were women, with a mean age of 39 years and a mean age of 32 years at diagnosis. Twenty-six patients had not received any previous treatment. Adherence varied between 93, 82 and 87.5% at 6, 12 and 24 months, respectively. No differences were found between patients who had not received any prior treatment and those who had been treated. Conclusion: This real-world analysis showed significant adherence to DMF treatment by Portuguese patients over a period of two years. However, these results must be interpreted in the light of the substantial changes in outpatient consultations and the various periodic restrictions due to the COVID-19 pandemic, which had an important effect on patient follow-up and data collection.(AU)

RESUMO

Introducción: El Registro Andaluz de Embarazos en pacientes con esclerosis múltiple (EM) es el mayor registro español sobre EM y planificación familiar. Por primera vez se incluye información sobre la fertilidad de hombres con EM. También se analizan la influencia del uso de un tratamiento modificador de la enfermedad (TME) en la salud del feto o recién nacido y el impacto de la lactancia materna en la EM. Sujetos y métodos: Es un estudio observacional, prospectivo y multicéntrico. El reclutamiento de pacientes se hizo entre diciembre de 2018 y diciembre de 2020. El seguimiento de las mujeres tras el parto fue de un año. Se incluyó a 100 mujeres y 16 hombres, con un total de 103 recién nacidos. Resultados: La tasa anualizada de brotes de las mujeres con EM descendió durante el embarazo de forma significativa (de 0,23 a 0,065). Un 11,2% de los pacientes recurrieron a técnicas de reproducción asistida para conseguir la gestación. No se encontró relación entre el uso de un TME en la concepción y/o embarazo y el riesgo de aborto, prematuridad o bajo peso al nacer. El 54,2% de las mujeres con EM optaron por dar lactancia (el 26,7% de ellas usando un TME). Conclusiones: La EM no afecta a la fertilidad de los hombres. Tampoco influye en ésta, ni en la salud de sus hijos, el uso de un TME en el momento de la concepción. Las técnicas de reproducción asistida no impactaron negativamente en la evolución de la EM. La lactancia se impone como una práctica habitual entre las mujeres con EM y no se evidencian efectos positivos o negativos sobre la evolución de la enfermedad.(AU)


Introduction: The Andalusian Registry of Pregnancies in patients with multiple sclerosis is the largest Spanish registry on multiple sclerosis (MS) and family planning. For the first time, it includes information on the fertility of men with MS. The influence of the use of a disease-modifying treatment (DMT) on the health of the foetus/newborn and the impact of breastfeeding on MS are also analysed. Subjects and methods: This is a multicentre, prospective and observational study. Recruitment of patients took place between December 2018 and December 2020. Women were followed up for one year after delivery. Altogether 100 women and 16 men were included, with a total of 103 newborn infants. Results: The annualised relapse rate of the women with MS decreased significantly during pregnancy (from 0.23 to 0.065). A total of 11.2% of patients resorted to assisted reproductive techniques in order to conceive a child. No association was found between the use of a DMT at conception and/or pregnancy and the risk of miscarriage, prematurity or low birth weight. Over half the women with MS (54.2%) chose to breastfeed (26.7% of them while on a DMT). Conclusions: MS does not affect the fertility of men. Neither does the use of a DMT at the time of conception affect their fertility or their children’s health. Assisted reproductive techniques did not have a negative impact on the course of MS. Breastfeeding is a common practice among women with MS and there is no evidence of positive or negative effects on disease progression.(AU)

RESUMO

Resumen Introducción: Existe poca información local sobre el riesgo de infección grave por COVID-19 en pacientes con esclerosis múltiple (EM) que reciben tratamiento modificador de la enfermedad (DMT). El objetivo del estudio fue evaluar el impacto de la enfermedad por COVID-19 (gravedad y letalidad) en pacientes con EM que reciben DMT. Métodos: El estudio se realizó sobre una cohorte prospectiva de pacientes con EM. Se incluyeron 111 con EM y diagnóstico confirmado de COVID-19 tratados con DMT, seguidos hasta la resolución del COVID-19. Resultados: Un total de seis (5.4%; IC 95%: 2-11.4%) desarrollaron COVID-19 grave definido como requerimiento de internación en terapia intensiva o muerte, y tres fallecieron (tasa de letalidad cruda del 2.7%; IC 95%: 1.1-4.3%). La tasa de letalidad ajustada por edad fue del 1.5% (IC 95%: 0.6-2.4%). El factor que se asoció independientemente con COVID-19 grave fue la edad (OR 1.1; IC 1.0-1.3; p < 0.05) con una tendencia en la Escala del Estado de Incapacidad Ampliada (EDSS) ≥ 6(OR 6.2; IC 0.6-56.4; p = 0.10). Conclusión: La letalidad por COVID-19 en pacientes con EM es baja y la gravedad se asoció significativamente con la edad y mostró una tendencia con EDSS ≥ 6.


Abstract Introduction: There is limited local information on the risk of severe COVID-19 infection in patients with multiple sclerosis (MS) who are receiving disease-modifying treatments (DMT). The aim of the study was to assess the impact of COVID-19 disease (severity and lethality) in MS patients receiving DMT. Methods: The study was performed on a prospective cohort with EM. We included 111 patients with MS and a confirmed di agnosis of COVID-19 treated with DMT and followed up until the resolution of COVID-19. Results: A total of six patients (5.4%; 95% CI: 2-11.4%) developed severe COVID-19 defined as requiring hospitalization in intensive care unit or death and three died (crude case fatality rate of 2.7%; 95% CI: 1.1-4.3%). The age-adjusted case fatality rate was 1.5% (95% CI: 0.6-2.4%). The factor that was independently associated with severe COVID-19 was age (OR 1.1; CI 1.0-1.3; p < 0.05) with a trend in the Expanded Disability Status Scale (EDSS) ≥ 6 (OR 6.2; CI 0.6-56.4; p = 0.10). Conclusion: The lethality due to COVID-19 in MS patients is low, and severity was significantly associated with age and showed a trend with EDSS ≥ 6.

RESUMO

Introducción: La esclerosis múltiple afecta principalmente a mujeres en edad fértil, y el período de gestación y posparto es de especial interés por las peculiaridades que comporta en cuanto a evolución de la enfermedad y por las consecuencias terapéuticas que se derivan. En el período de lactancia materna (LM), la elección de la estrategia de tratamiento debe poner en una balanza, por un lado, los beneficios bien establecidos de la LM para el recién nacido y su madre y, por el otro, el perfil de seguridad y potenciales efectos adversos en el lactante derivados de la exposición a los fármacos modificadores de la enfermedad, por transferencia a través de leche materna. Desarrollo: Se realiza una revisión de la evidencia actual acerca de la seguridad de los fármacos modificadores de la enfermedad disponibles para el tratamiento de la esclerosis múltiple durante el período de LM, y se recogen datos de transferencia de los diferentes fármacos a la leche materna, así como los potenciales efectos adversos descritos en el lactante. Los fármacos considerados de primera elección durante este período son el interferón beta y el acetato de glatiramer. El resto de los fármacos modificadores de la enfermedad no están aceptados para su utilización en el período de LM por ficha técnica. Sin embargo, en los últimos años, se han publicado datos de estudios de práctica clínica y series de casos que indican que algunos de estos fármacos podrían utilizarse con seguridad durante este período. Conclusiones: Teniendo en cuenta los beneficios reconocidos de la LM para la salud tanto de la madre como del lactante, se debe recomendar la LM exclusiva a las pacientes con esclerosis múltiple siempre que sea posible. Es fundamental realizar una evaluación individualizada previa al embarazo y valorar las diferentes opciones de tratamiento en función de cada paciente.(AU)


Introduction: Multiple sclerosis mainly affects women of childbearing age, and the pregnancy and postpartum period is of special interest because of the peculiarities of the disease course and the therapeutic consequences that derive from it. During the period of breastfeeding (BF), the choice of treatment strategy must weigh up the well-established benefits of BF for both the newborn and the mother against the safety profile and potential adverse effects on the infant resulting from exposure to disease-modifying drugs transferred through breast milk. Development: The study reviews the current evidence on the safety of disease-modifying drugs available for the treatment of multiple sclerosis during the BF period, and gathers data on the transfer of the different drugs into breast milk, as well as the potential adverse effects described in the infant. The drugs of first choice during this period are interferon beta and glatiramer acetate. The rest of the disease modifying drugs are not accepted for use in the BF period according to their summary of product characteristics. However, in recent years, data from studies of clinical practice and case series have been published suggesting that some of these drugs could be used safely during this period. Conclusions: Given the recognised health benefits of BF for both mother and infant, exclusive breastfeeding is recommended whenever possible. It is essential to carry out an individualised assessment prior to pregnancy and to evaluate the different treatment options depending on each patient.(AU)

RESUMO

Introducción: El efecto de la infección por SARS-CoV-2 en los pacientes con esclerosis múltiple (EM) y la influencia de los tratamientos modificadores de la enfermedad (TME) es desconocida. Hasta el momento no se ha observado que los pacientes con EM tengan mayor riesgo de infección por COVID-19, ni peor curso evolutivo de la misma.MétodosEstudio descriptivo de pacientes con EM e infección por SARS-CoV-2 diagnosticada mediante PCR. Hemos analizado variables demográficas, clínicas, de laboratorio y de tratamiento en nuestra muestra. Se ha determinado la presencia de anticuerpos frente a SARS-CoV-2 en estos pacientes.ResultadosLa forma de esclerosis múltiple remitente recurrente (EMRR) fue la más frecuente en lo pacientes con EM e infección por COVID-19. El 10,2% presentó una evolución desfavorable, relacionada con una mayor edad y una Expanded Disability Status Scale (EDSS) más elevada. La seroprevalencia de anticuerpos frente a SARS-CoV-2 en nuestro estudio ha sido del 83,3%. El desarrollo de anticuerpos no está relacionado con el TME, la presencia de linfopenia u otros factores analizados.ConclusionesLa incidencia de COVID-19 ha sido ligeramente inferior a la de la población general de nuestra provincia. La evolución desfavorable se ha relacionado con una mayor edad y una puntuación elevada en la EDSS. El TME y la linfopenia no se han relacionado con el curso de la infección por COVID-19. La seroprevalencia es similar a la encontrada en población general con PCR positiva, sin poder determinar la influencia de los distintos TME. (AU)

RESUMO

Resumen La adherencia al tratamiento prescrito en enfermedades crónicas, como ocurre en la esclerosis múltiple (EM), es un factor crítico para una respuesta terapéutica exitosa. El objetivo de este estudio fue evaluar la asociación entre las variables demográficas y la adherencia al tratamiento en una población de pacientes con EM en Argentina. Se realizó un estudio de cohorte retrospectivo de pacientes con EM que recibieron tratamiento con medicamentos modificadores de la enfermedad, incluidos en la base de datos de dispensación de medicamentos del Programa Nacional de Atención Médica: PAMI (Programa Asistencia Médica Integral). La adherencia óptima se definió como una adquisición del fármaco superior al 80% durante un seguimiento de 9 meses. Se incluyó un total de 648 pacientes, edad media 55 años (RIC 46-64), 59.4% mujeres. La adherencia media al tratamiento fue del 67% (RIC 44-89) y la adherencia óptima se documentó solo en el 35.5% de los casos. La adherencia a los medicamentos inyectables fue 10% menor que la de los medicamentos orales (p = 0.0001) y el uso de marcas originales se asoció con una adherencia 7.4% mayor que los medicamentos genéricos (p = 0.001). En conclusión, la adherencia al tratamiento ha sido subóptima. En la región patagónica, el uso de inyectables y de medicamentos genéricos se asoció con una menor adherencia terapéutica. Estos datos son muy importantes para planificar programas socio-sanitarios que tengan como objetivo aumentar la adherencia terapéutica.


Abstract Adherence to prescribed treatment in chronic diseases, as occurs in multiple sclerosis (MS), is a critical factor for a successful therapeutic response. The objective of this study was to evaluate the association between demographic variables and adherence to treatment of the population of MS patients in Argentina. A retrospective cohort study of MS patients who received treatment with disease-modifying drugs, included in the drug dispensing database of the National Care Medical Program: PAMI (Programa Asistencia Médica Integral), was conducted. Optimal adherence was defined as an acquisition of the drug greater than 80% during a 9-month follow-up. A total of 648 patients were included, mean age 55 years (IQR 46-64), 59.4% women. The mean adherence to treatment was 67% (IQR 44-89) and optimal adherence was documented only in 35.5% of cases. Adherence to injectable medications was 10% lower than that of oral drugs (p = 0.0001) and the use of original brands was associated with 7.4% greater adherence than with generic drugs (p = 0.001). In conclusion, adherence to treatment has been suboptimal. In the Patagonian region, the use of injectables and generic drugs was associated with lower adherence to therapy. These data are very important in order to planning socio-sanitary programs that aim to increase therapeutic adherence.
