Abstract

Introduction: Treatment of multiple sclerosis is based on the administration of the disease modifying drugs (DMD), used to slow the natural course of the disease.

Aim: To assess the degree of compliance of Spanish neurologists with 2010 Spanish Neurology Society (SEN) treatment guidelines.

Patients and methods: Observational, retrospective and multicenter study of 218 adult patients with at least five years of disease evolution and under treatment with DMD. Data on their past/current management was obtained from their medical records and descriptively compared to SEN recommendations.

Results: According to SEN 2010 guidelines, 82% of patients had an adequate clinical response and 18% had an inadequate clinical response to their current DMD; 94% and 92%, respectively, maintained that treatment. Patients in which inadequate clinical response did not motivate a change in the current DMD more frequently had higher disability decline and higher number of relapses during previous treatments, and longer treatment duration with their current DMD. Regarding the sequence of DMDs used, 48% of patients initiated first-line treatment with interferon beta-1a administered through subcutaneous (29%) or intramuscular injections (19%), followed by interferon beta-1b, and glatiramer acetate. Some patients received second-line treatments as second/third option (15% and 28% respectively), but these treatments (mostly natalizumab) were only widespread from fourth treatment onwards.

Conclusions: In accordance with SEN 2010 guidelines, the majority of patients from the study had an adequate clinical response. A high percentage of patients with an inadequate clinical response remained with their current treatment. An explanation to this phenomenon could be found in the chronic, complex and variable nature of multiple sclerosis.

Title: Cumplimiento de las guias de la Sociedad Española de Neurologia en el tratamiento de los pacientes con esclerosis multiple.

Introduccion. El tratamiento de la esclerosis multiple se basa en la administracion de farmacos modificadores de la enfermedad (FAME), utilizados para frenar el curso natural de la enfermedad. Objetivo. Evaluar el grado de cumplimiento de las guias terapeuticas de la Sociedad Española de Neurologia (SEN) de 2010 por parte de los neurologos. Pacientes y metodos. Estudio observacional, retrospectivo y multicentrico de 218 pacientes adultos con esclerosis multiple de al menos cinco años de evolucion y en tratamiento con FAME. Los datos se obtuvieron de la historia clinica y se compararon con las recomendaciones de la SEN. Resultados. Segun las guias de la SEN de 2010, el 82% de los pacientes presentaba respuesta clinica adecuada, y el 18%, respuesta clinica inadecuada al FAME actual; el 94% y 92%, respectivamente, mantuvieron ese tratamiento. Los pacientes en los que la respuesta clinica inadecuada no origino un cambio del FAME actual llevaban en tratamiento mas tiempo y experimentaron con mayor frecuencia progresion de su discapacidad e incremento del numero de brotes. El 48% de los pacientes inicio tratamiento de primera linea con interferon beta-1a, administrado por via subcutanea (29%) o intramuscular (19%), seguido de interferon beta-1b y acetato de glatiramero. Algunos pacientes recibieron tratamientos de segunda linea como segunda/tercera opcion (15% y 28%, respectivamente), pero el uso de estos tratamientos (especialmente natalizumab) solo se generalizo a partir de la cuarta linea de tratamiento. Conclusiones. De acuerdo con las guias de la SEN de 2010, la mayoria de los pacientes tuvo una respuesta clinica adecuada. Un elevado porcentaje de pacientes con respuesta clinica inadecuada continuo con el tratamiento actual.
