ABSTRACT

INTRODUCTION: Fingolimod is a selective immunosuppressant that targets the S1P receptor, and is indicated in the treatment of aggressive relapsing-remitting multiple sclerosis (RRMS) and following treatment failure with first-order drugs. AIM: To investigate the safety and effectiveness of fingolimod under the conditions of routine clinical practice. PATIENTS AND METHODS: We conducted an observational study with prospective follow-up of patients with RRMS who received fingolimod from January 2011 until February 2014. Data assessed were the annualised relapse rate (ARR), disability measured by the Expanded Disability Status Scale (EDSS), magnetic resonance activity and the appearance of side effects. RESULTS: Our sample consisted of 122 patients, 79.5% of them females and with a mean age of 26.8 years. They were classified, according to the last treatment received, as being: naive (aggressive RRMS; n = 17), previous treatment failure (n = 67) and withdrawal of natalizumab due to risk of progressive multifocal leukoencephalopathy (n = 38). After a mean follow-up of 29.9 ± 15.9 months, the ARR and the appearance of new lesions with gadolinium enhancement were reduced in both the naive and the previous treatment failure groups. There were no differences between the various subgroups as regards the progression of EDSS or the time elapsed until the first attack or treatment failure. The risk of treatment failure is higher with a baseline EDSS > 3 (hazard ratio: 4.24; p = 0.001) and presence of IgM oligoclonal bands (hazard ratio: 2.45; p < 0.022). CONCLUSIONS: Fingolimod is an effective and well-tolerated drug under conditions of routine clinical practice. Having a baseline EDSS > 3 and IgM oligoclonal bands is predictive of a poor response to fingolimod.


TITLE: Tratamiento de la esclerosis multiple remitente recurrente con fingolimod en la practica clinica habitual.Introduccion. El fingolimod es un inmunosupresor selectivo dirigido contra el receptor SP-1, indicado en el tratamiento de la esclerosis multiple remitente recurrente (EMRR) agresiva y tras el fracaso del tratamiento con farmacos de primera linea. Objetivo. Investigar la seguridad y efectividad del fingolimod en condiciones de practica clinica habitual. Pacientes y metodos. Estudio observacional con seguimiento prospectivo de pacientes con EMRR que recibieron fingolimod desde enero de 2011 hasta febrero de 2014. Se evaluo la tasa anual de brotes (TAB), la discapacidad medida por la escala expandida del estado de discapacidad (EDSS), la actividad en la resonancia magnetica y la aparicion de efectos adversos. Resultados. Incluimos 122 pacientes, el 79,5% mujeres y con una edad media de 26,8 antilde;os. Se clasificaron segun el ultimo tratamiento recibido en: naive (EMRR agresiva; n = 17), fracaso a terapias previas (n = 67) y retirada de natalizumab por riesgo de leucoencefalopatia multifocal progresiva (n = 38). Tras un seguimiento medio de 29,9 ± 15,9 meses, se redujo de forma significativa la TAB y la aparicion de nuevas lesiones con realce de gadolinio en el grupo naive y el de fracaso a terapias previas. No ha habido diferencias en la evolucion de la EDSS ni en el tiempo hasta el primer brote o el fracaso terapeutico entre los diferentes subgrupos. El riesgo a fracaso terapeutico es mayor con la EDSS basal > 3 (hazard ratio: 4,24; p = 0,001) y presencia de bandas oligoclonales IgM (hazard ratio: 2,45; p < 0,022). Conclusiones. El fingolimod es un farmaco eficaz y seguro en la EMRR en condiciones de practica clinica habitual. Tener una EDSS basal > 3 y bandas oligoclonales IgM predice una mala respuesta al fingolimod.

ABSTRACT

Introducción: La neuromielitis óptica es un trastorno autoinmune, inflamatorio y desmielinizante del sistema nervioso central que afecta a la médula espinal y al nervio óptico, de carácter recurrente. Rituximab ha sido utilizado en el tratamiento de varias enfermedades neurológicas de probable naturaleza autoinmune o donde la inmunidad humoral estaba implicada. El objetivo de este estudio es evaluar la eficacia y seguridad de rituximab en el tratamiento de la neuromielitis óptica en un hospital terciario. Métodos: Estudio retrospectivo de pacientes con neuromielitis óptica tratadas con 2 infusiones de rituximab 1.000 mg separadas por 15 días, cada 6-8 meses. Se evaluó la puntuación EDSS, la existencia de brotes, el estado general, el recuento de CD19+, la presencia de anticuerpos anti-NMO y las reacciones adversas. Resultados: Se trataron 6 pacientes, todas mujeres (mediana de edad 46 años; rango 38-58). En 3 de ellas (50%) se detectó la presencia de anticuerpos anti-NMO. La EDSS basal fue de 4 (rango 2-5,5). Dos pacientes recibieron previamente algún fármaco inmumodulador. La mediana desde el primer brote hasta el tratamiento con rituximab fue de 3,7 años (rango 1,7-6,9); 2 pacientes presentaron alguna reacción adversa tras la primera infusión del fármaco. En cuanto a la respuesta, 4 pacientes no volvieron a tener brotes y su EDSS no progresó, en una paciente no se observó mejoría clínica y otra no pudo evaluarse. Conclusiones: El uso de rituximab en pacientes con neuromielitis óptica puede considerarse una alternativa terapéutica interesante, ya que no existen tratamientos autorizados para esta enfermedad. Son necesarios más estudios con rituximab para establecer el lugar de este fármaco en la terapéutica de la neuromielitis óptica


Introduction: Neuromyelitis optica is an inflammatory and usually relapsing demyelinating autoimmune disease of the central nervous system that targets the optic nerves and spinal cord. Rituximab has been used for different neurological diseases that are probably immune-mediated or involving humoural immunity. The objective of this study is to evaluate the efficacy and safety of rituximab as treatment for neuromyelitis optica in a tertiary hospital. Methods: Retrospective study of patients with neuromyelitis optica treated with rituximab 1000 mg on days 1 and 15, repeated every 6 to 8 months. We recorded EDSS score, relapse rate, overall condition, CD19+ count, presence of anti-NMO antibodies, and possible adverse reactions. Results: Six patients were treated; all were women with a median age of 46 years (range, 38-58). Anti-NMO antibodies were detected in 3 patients (50%). Baseline EDSS was 4 (range 2.0-5.5). Two patients had previously been treated with an immunomodulatory drug. Median time from the first rituximab infusion to first relapse was 3.7 years (range 1.7-6.9). Two patients had infusion reactions after the first dose of rituximab. Four patients remained relapse-free and their EDSS score did not progress during rituximab treatment, one patient showed no clinical improvement, and one patient could not be evaluated. Conclusion: Rituximab can be considered an attractive therapeutic alternative for patients with neuromyelitis optica as there are no approved treatments for this disease. Further studies with rituximab are needed to establish the role of this drug in treating neuromyelitis optica
