ABSTRACT

OBJECTIVE:

To determine if the presence of oligoclonal bands (OB) at early stages of multiple sclerosis was associated with higher brain atrophy, when compared with patients without OB.

METHODS:

Relapsing-remitting multiple sclerosis (RRMS) patients with less than two years of disease onset and OB detection in cerebrospinal fluid (CSF) were included. SIENAX was used for total brain volume (TBV), gray matter volume (GMV), and white matter volume (WMV).

RESULTS:

Forty patients were included, 29 had positive IgG-OB. No differences were found between positive and negative patients in gender, expanded disability status scale (EDSS), treatment received, and T2/T1 lesion load. TBV in positive IgG-OB patients was 1.5 mm³ x 10(6) compared with 1.64 mm³ x 10(6) in the negative ones (p=0.02). GMV was 0.51 mm³ x 10(6) in positive IgG-OB compared with 0.62 mm³ x 10(6) in negative ones (p=0.002). No differences in WMV (p=0.09) were seen.

CONCLUSIONS:

IgG-OB in the CSF was related to neurodegeneration magnetic resonance (MR) markers in early RRMS.
RESUMEN

OBJETIVO:

Evaluar si la presencia de bandas oligoclonales (BO) en líquido cefalorraquídeo (LCR) de pacientes con esclerosis múltiple recaídaremisión (EMRR) se asociaba con mayor atrofia cerebral al inicio de la enfermedad.

MÉTODOS:

Pacientes con EMRR con menos que dos años del inicio de la enfermedad y en quiénes se realizó la búsqueda de IgG-BO en LCR fueron incluidos. SIENAX fue usado para la medición del volumen cerebral total (VCT), volumen de substancia gris (VSG) y volumen de sustancia blanca (VSB).

RESULTADOS:

Cuarenta pacientes fueron incluidos, 29 tenían IgG-BO positivo. No fueron encontradas diferencias entre pacientes positivos y negativos en género, expanded disability status scale (EDSS), tratamiento recibido y carga lesional en resonancia magnética. El VCT en pacientes IgG-BO positivos fue de 1,5 mm³ x 10(6) versus 1,64 mm³ x 10(6) en BO negativo (p=0,02). El VSG fue 0,51 mm³ x 10(6) BO positivo versus 0,62 mm³ x 10(6) BO negativo (p=0,002). No fueron encontradas diferencias en VSB (p=0,09).

CONCLUSIONES:

La presencia de IgG-BO en el LCR se asoció con signos de neurodegeneración temprana en este estudio.
