Abstract

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.
