The etiology of multiple sclerosis (MS), a chronic demyelinative disease-is unknown. The damage of
blood-brain barrier (BBB) vasculature is a characteristic of MS and Homocystein (Hcy) can damage BBB, then increase
in total Hcy may be important in MS pathogenesis. The aim of this study was to compare the serum level of total
Hcy in MS patients with control group.
Methods: In a case control stud y, serum level of total Hey measured in 35 MS patient and compared with 30 healthy
matched controls. All patients had definitive MS according to Poser criteria, without history of myocardial infarction,
stroke, neuropathy, transient ischemic attack, hornocystinuria Orrenal failure .
Results: The serum concentration of total homocystein was significantly higher in multiple sclerosis patients than
healthy controls . The mean total Hey level was 17.92± 6.9 mmol/lit in cases and 14.6±2.92 mmol/lit in controls
(P=0.013). .
.. Conclusion: Serum total Homocystein may have a role in MS pathogenesis and reduction of it should be studied
moreover.
