Title
(EN) BIOMARKERS FOR IDENTIFYING RELAPSES IN MULTIPLE SCLEROSIS
(FR) BIOMARQUEURS POUR L'IDENTIFICATION DES RECHUTES DANS LA SCLÉROSE EN PLAQUES
Abstract
(EN) The present invention includes a method of predicting and/or treating a recurrence of MS treating a patient with multiple sclerosis, the method comprising: obtaining a hematopoietic cell sample from a patient suspected of having a recurrence of multiple sclerosis (MS), wherein the patient was in relapse for MS; determining the number of CD19+, CD24+, CD38+ transitional B cells in the hematopoietic cell sample, and a level of expression of neurofilament light (NFL) and interleukin-1β (IL-1β), which is predictive of a recurrence of MS; and treating the MS patient with recurrence until there is an increase in CD19+, CD24+, CD38+ transitional B cells and/or a decrease in a level of expression of NFL and interleukin-1β (IL-1β) when compared to an untreated MS control sample, an unresponsive MS control sample, or an MS patient with long-term stable disease sample.
(FR) La présente invention concerne une méthode de prédiction et/ou de traitement d'une rechute de SEP chez un patient atteint de sclérose en plaques, la méthode comprenant les étapes consistant à : prélever un échantillon de cellules hématopoïétiques chez un patient chez lequel on soupçonne une rechute de sclérose en plaques (SEP), le patient subissant une poussée de SEP; déterminer le nombre de lymphocytes B transitoires CD19+, CD24+, CD38+ dans l'échantillon de cellules hématopoïétiques, et un niveau d'expression de protéines légères de neurofilaments (NFL) et d'interleukine-1β (IL-1β), qui est révélateur d'une rechute de la sclérose en plaques; et traiter le patient atteint de SEP présentant une rechute jusqu'à augmentation des lymphocytes B transitoires CD19+, CD24+, CD38+ et/ou diminution du niveau d'expression des NFL et de l'interleukine-1β (IL-1β) par comparaison avec un échantillon témoin SEP non traité, un échantillon SEP témoin non réactif, ou un échantillon d'un patient souffrant d'une SEP stabilisée depuis longtemps.
