Background: ALS is an oxidative stress-related fastpaced
motor neuron disease for which there are no
accurate biomarkers of progression. This largely hampers
the development of therapeutics. Our aim was to test the
applicability of oxidation-reduction potential (ORP) of
cerebrospinal fluid (CSF) in ALS progression follow-up.
Methods: ORP was measured using RedoxSYS (Aytu
BioScience, Inc.) in CSF of 49 ALS patients (mean age
63 1.29 years; range 43-80 years; mean ALSFRSr score
37.47 0.90, range 21-48; m/f = 35/14) and 15 controls
(mean age 48.93 3.68 years, range 21-67 years; m/f =
10/5).
Results: Pearson correlation coefficient (R) between
ALSFRSr score and ORP was 0.27 (p = 0.06). R was
higher ( 0.45) when two outlier values were excluded
from the calculus. Importantly, ALS patients had significantly
higher mean ORP (ALS: 121.83 2.76mV;
controls: 111.14 2.94 mV; p = 0.033). The difference
was also significant for ORP normalized to age. Of note,
ORP is reciprocally p...roportional to the pro-oxidative
settings in biological samples.
Discussion: Increased ORP values in ALS patients
further confirm the role of oxidative stress in this
neurodegenerative disease. ORP might find application
as a biomarker for ALS progression/prognosis but further
measurements on a larger cohort is warranted.
