Background:
The chronic inflammation associated with multiple sclerosis (MS) may lead to the upregulation of pentosidine.
Objectives:
This cross-sectional study compares plasma pentosidine levels among healthy controls (HCs) and patients with MS at different disease stages. The study also determines pentosidine's usefulness as a biomarker of MS disease activity and/or severity via its correlation with a number of indicators of MS disease.
Methods:
Pentosidine levels were analyzed in 98 MS patients and 43 HCs using reverse-phase high-pressure liquid chromatography with fluorescence detection.
Results:
Plasma pentosidine levels were significantly higher in MS patients when compared with HCs (p = 0.02). Patients on disease-modifying therapies (DMTs) had lower plasma pentosidine levels when compared with DMT-naïve patients (p = 0.01). Pentosidine plasma levels correlated with indicators of MS disease severity, including Extended Disability Status Scale (p = 0.03), MS Severity Scale (p = 0.01), and MS Functional Composite (p = 0.03). No correlation between pentosidine levels and age, rate of clinical relapse, and disease duration was observed.
Conclusions:
Our results suggest that pentosidine could be a novel, inflammatory biomarker in MS clinical practice. Longitudinal studies are warranted to determine any causal relationship between changes in plasma pentosidine levels and MS disease pathology. These studies may pave the way for use of advanced glycation end product (AGE) inhibitors and AGE-breaking agents as new therapeutic modalities in MS.
