Abstract:
Objective To investigate whether vitamin B complex supplements would reduce stroke-related disabili-ty in hyperhomocysteinemia (Hhcy) patients with recent ischemic stroke. Methods One thousand patients with brain infarc-tion and Hhcy were assigned to receive either a daily dose of vitamin B complex (treatment group, n=500) or not (control group, n=500) on the base of conventional secondary prevention medications for a period of 2 years. The neurological dys-function was assessed by National Institutes of Health Stroke Scale (NIHSS) and stroke disability was evaluated by Barthel Index (BI) score. High performance liquid chromatographic method with fluorescence detection was used for the determina-tion of total plasma homocysteine levels. After 2 years of follow-up, the patients in the treatment group, whose tHcy level was reduced by 3-μmol/L or more, was defined as the treatment subgroup. Results The homocysteine levels were significantly reduced after 3, 12 and 24-month treatment than those of control group (P＜0.05). A lower NIHSS scale was found at 12, 18 and 24-month in treatment group compared with that in control group (P＜0.05), no significant differences at other time points between two groups (P>0.05). For the BI score, there were no significant differences at any time points between two groups (P>0.05). After 2 years of vitamin B complex supplementation, there were lower NIHSS scale and higher BI scale in treatment subgroup than those of control group (P＜0.05). Conclusion The lower level of tHcy induced by vitamin B inter-vention may be beneficial to the improvement of neurological deficit in patients with ischemic stroke.
