Abstract
Serial recordings of multimodal sensory (visual, acoustic and somatosensory) evoked potentials were made in 19 relapsing-remitting Multiple Sclerosis patients enrolled in a clinical trial designed to evaluate the efficacy of dexamethasone versus high-and low-dose methylprednisolone in acute multiple sclerosis bouts. Electrophysiological and clinical evaluations were performed at the onset of therapy and until 6 months after the end of treatment. Using an arbitrary Evoked Potentials score that takes into account both latency and waveform alterations, we found a positive correlation between evoked potentials and clinical disability scores. Furthermore, different electrophysiological profiles were detected in the three therapeutic subgroups. Evoked potentials may be useful for monitoring acute Multiple Sclerosis bouts and evaluating the effect of therapy.
Sommario
I potenziali evocati visivi, acustici e somatosensoriali sono stati monitorati in 19 pazienti affetti da Sclerosi Multipla, inclusi in un trial clinico volto alla valutazione dell' efficacia del desametazone e di basse e alte dosi di metilprednisolone nel trattamento delle riaccensioni della malattia. La valutazione clinica ed elettrofisiologica veniva effttuata all'inizio e alla fine del trattamento (a 15 giorni) e a 3 e 6 mesi dopo la sospensione. Utilizzando una scala arbitraria elettrofisiologica che prendeva in considerazione sia le alterazioni di latenza che di morfologia, abbiamo riscontrato una correlazione positiva tra punteggio elettrofisiologico e disabilità clinica. Inoltre differenti profili elettrofisiologici erano osservati nei tre sottogruppi terapeutici. Lo studio dei potenziali evocati appare utile nel monitoraggio delle riaccensioni della malattia e nella valutazione dell' effetto della terapia.
