Summary
Elevated homocysteine is common in multiple sclerosis (MS) patients, regardless of disease course. This increase appears unrelated to immune factors, oxidative stress, or vitamin deficiencies.
Area of Science:
- Neuroscience
- Immunology
- Metabolic Disorders
Background:
- Homocysteine is implicated in neurodegenerative disorders.
- Elevated plasma homocysteine is observed in multiple sclerosis (MS) patients.
Purpose of the Study:
- Investigate elevated plasma homocysteine levels in MS.
- Determine the role of homocysteine in MS disease course.
- Explore underlying mechanisms for increased homocysteine in MS.
Main Methods:
- Compared plasma homocysteine levels in 88 MS patients and 57 healthy controls.
- Analyzed homocysteine levels across MS clinical subtypes (benign, secondary progressive, primary progressive).
- Measured serum vitamins B6, B12, folate, inflammatory markers (IL-12, TNF-alpha), nitric oxide production, and oxidative stress markers.
Main Results:
- MS patients exhibited significantly higher plasma homocysteine (13.8 µmol/l) than controls (10.1 µmol/l).
- No significant differences in homocysteine levels were found between MS clinical subtypes.
- Homocysteine levels did not correlate with vitamin status, inflammatory markers, nitric oxide, or oxidative stress in MS patients.
Conclusions:
- Elevated plasma homocysteine is present in both benign and progressive MS.
- The elevation of homocysteine in MS is not linked to immune activation, oxidative stress, or deficiencies in vitamins B6, B12, or folate.
