Background:
Multiple sclerosis (MS) is an immune-mediated demyelinating disorder of the central nervous system. The glycosphingolipid sulfatide, a lipid particularly enriched in the myelin sheath, has been shown to be involved the maintenance of this specific membrane structure. Sulfatide in cerebrospinal fluid (CSF) may reflect demyelination, a dominating feature of MS. We investigated the diagnostic utility of CSF sulfatide isoform levels to separate different courses or phenotypes of MS disease.
Material And Methods:
This was a mono-center, cross-sectional study of relapsing-remitting MS (RRMS) (n = 45) and progressive MS (PMS) (n = 42) patients (consisting of primary PMS (n = 17) and secondary PMS (n = 25)) and healthy controls (n = 19). In total, 20 sulfatide isoforms were measured in CSF by liquid chromatography-mass spectrometry.
Results:
CSF total sulfatide concentrations, as well as CSF sulfatide isoform distribution, did not differ across the study groups, and their levels were independent of disease course/phenotype, disease duration, time to conversion to secondary PMS, age, and disability in MS patients.
Conclusion:
CSF sulfatide isoforms lack diagnostic and prognostic utility as a biomarker for progressive MS.
Insights
Cerebrospinal fluid sulfatide isoforms do not help distinguish multiple sclerosis (MS) disease courses. Measuring these sulfatide levels in CSF is not a useful biomarker for diagnosing or predicting progression in MS.
Area of Science:
- Neuroimmunology
- Biochemistry
- Clinical Diagnostics
Background:
- Multiple sclerosis (MS) is an immune-mediated central nervous system disorder characterized by demyelination.
- Sulfatides, glycosphingolipids vital for myelin sheath structure, are found in cerebrospinal fluid (CSF).
- CSF sulfatide levels may indicate demyelination, a key feature of MS.
Purpose of the Study:
- To investigate the diagnostic utility of CSF sulfatide isoform levels.
- To differentiate between various multiple sclerosis disease courses and phenotypes.
Main Methods:
- A cross-sectional study involving patients with relapsing-remitting MS (RRMS), primary progressive MS (PMS), and secondary progressive MS (SPMS), alongside healthy controls.
- Quantification of 20 distinct sulfatide isoforms in CSF using liquid chromatography-mass spectrometry.
Main Results:
- No significant differences in total CSF sulfatide concentrations or isoform distribution were observed among the study groups.
- CSF sulfatide levels were found to be independent of MS disease course, duration, age, and disability.
- No correlation was found between CSF sulfatide levels and time to conversion to secondary progressive MS.
Conclusions:
- CSF sulfatide isoforms do not possess diagnostic or prognostic value for identifying progressive forms of MS.
- The current findings suggest that CSF sulfatides are not suitable biomarkers for differentiating MS phenotypes.
