Background:
Chitinase-3-like protein 1 (CHI3L1), secreted by immune cells, plays a key role in modulating immune responses. Syndecan-1 (SDC-1), a cell surface heparan sulfate proteoglycan, is involved in the regulation of inflammation. This study aimed to evaluate whether CHI3L1 and soluble SDC-1 (sSDC-1) act as potential diagnostic targets in patients with relapsing-remitting multiple sclerosis (RRMS).
Methods:
sSDC-1 and CHI3L1 levels were quantified using enzyme-linked immunosorbent assay (ELISA) in cerebrospinal fluid (CSF) samples collected from a cohort of 39 newly diagnosed patients with relapsing-remitting multiple sclerosis (RRMS) and 32 disease controls diagnosed with idiopathic intracranial hypertension (IIH).
Results:
No significant difference was observed in CSF sSDC-1 levels between the RRMS and IIH groups. However, CSF CHI3L1 levels were significantly lower in patients with RRMS compared to those with IIH.
Conclusion:
The present findings do not provide clear evidence supporting a diagnostic role for CSF levels of sSDC-1 or CHI3L1 in MS.
