Hyperhomocysteinemia, folateo and B12 vitamin in Iranian patients with acute ischemic stroke

Abstract

BACKGROUND: The objective of this study was to evaluate the association of some factors such
as serum levels of homocysteine, folate and B12 vitamin with stroke in acute ischemic stroke
patients.
METHODS: In this case control study, serum levels of homocysteine, folate and B12 vitamin in
93 patients with acute ischemic stroke admitted to Imam Khomeini Hospital between
September 2008 and January 2010, and 93 healthy controls were measured. Cerebrovascular
risk factors including age, sex, hypertension, hyperlipidemia, smoking, diabetes mellitus,
alcohol consumption, coronary artery disease and obesity were recorded. The results were
compared between the case and control groups.
RESULTS: The mean ± standard deviation (SD) of fasting total homocysteine (tHcy) level in
acute ischemic stroke patients was 20.58 ± 19.6 0mol/L, which was significantly higher than
that of control group being 14.11 ± 9.5 0mol/L (P = 0.002). 39 (41.9%) stroke cases and 25
(26.8%) controls had hyperhomocysteinemia. There were no significant relationships between
tHcy, folate and B12 vitamin levels with the above mentioned cerebrovascular risk factors except
for smoking (p> 0.05). No significant difference in B12 vitamin and folate levels between
patients and healthy controls were detected (P> 0.05).
CONCLUSION: Hyperhomocysteinemia is common in Iranian patients with acute ischemic
stroke and might play a role as an independent risk factor in stroke.
