ABSTRACT

Resumen El objetivo del estudio fue evaluar los aspectos clínicos y demográficos de los pacientes con esclerosis múltiple (EM) secundaria progresiva (EMSP) en los pacientes incluidos en el Registro Argentino de EM (RelevarEM, número de registro de Clinical Trials 03375177). RelevarEM es un registro longitudinal, estrictamente observacional, de pacientes con EM y trastornos del espectro de neuromielitis óptica. Los aspectos clínicos y demográficos fueron descriptos en pacientes con EMSP respecto a aquellos con EM recaída en remisión (EMRR). Se incluyeron 1723 pacientes con EM (1605, 93.2% EMRR y 118, 6.8%, EMSP). En el grupo con EMSP la mediana de edad fue de 53 (intervalo inter-cuartil [IIQ] 47-62) años, 67% eran mujeres, mediana de tiempo de evolución de enfermedad 19.5 (IIQ 14-26) años, EDSS (expanded disability status scale), 6.5 y 48.3% estaban en tratamiento para su EM. Solo el 23.7% con EMSP estaban trabajando activamente y el 86% tenía certificado de discapacidad. Un 35.6% con EMSP presentaron nuevas lesiones en resonancia magnética y 5% tuvo recaídas clínicas en los 12 meses previos al análisis, mostrando una actividad de la enfermedad significativamente menor respecto a la forma EMRR (p < 0.01).


Abstract The objective of the study was to describe the clinical and demographic aspects of patients with secondary progressive multiple sclerosis (SPMS) included in the Argentine MS Registry (RelevarEM, Clinical Trials registry number 03375177). RelevarEM is a longitudinal, strictly observational registry of patients with MS and neuromyelitis optica spectrum disorders. Clinical and demographic aspects were described in patients with SPMS and compared with relapsing remitting MS patients (RRMS). A total of 1723 patients with MS were included (1605, 93.2% RRMS and 118, 6.8%, SPMS). In SPMS, the median age was 53 (inter quartile range [IQR] 47-62) years, 67% were women, median disease duration of 19.5 (IQR 14-26) years, median EDSS (expanded disability status scale) 6.5 and 48.3% were under treatment for their MS. Only 23.7% of patients with SPMS were actively working and 86% had a disability certificate; 35.6% of patients with SPMS presented new lesions in MRI and 5% had clinical relapses during the past 12 months of the registry entry showing a significantly lower disease activity compared with RRMS (p < 0.01).

ABSTRACT

ABSTRACT Multiple sclerosis (MS) was always considered as a white matter inflammatory disease. Today, there is an important body of evidence that supports the hypothesis that gray matter involvement and the neurodegenerative mechanism are at least partially independent from inflammation. Gray matter atrophy develops faster than white matter atrophy, and predominates in the initial stages of the disease. The neurodegenerative mechanism creates permanent damage and correlates with physical and cognitive disability. In this review we describe the current available evidence regarding brain atrophy and its consequence in MS patients.


RESUMEN La esclerosis múltiple (EM) fue considerada históricamente como una enfermedad inflamatoria de la sustancia blanca. Hoy en día hay mucha evidencia que apoya, además, el compromiso de la sustancia gris y los mecanismos neurodegenerativos, que son al menos parcialmente independientes de la inflamación. La atrofia de la sustancia gris se desarrolla más rápido que la atrofia de la sustancia blanca y predomina en las etapas iniciales de la enfermedad. El mecanismo neurodegenerativo, crea un daño permanente y se correlacionaría con la discapacidad física y cognitiva del paciente. En esta revisión, se describe la evidencia disponible actual con respecto a la atrofia cerebral y su consecuencia en los pacientes con EM.
