Abstract:
Objective To investigate the relationship between MTHFR C677T gene polymorphism and peripheral edema after intracerebral hemorrhage.Methods Two hundred and sixteen patients with hypertensive intracerebral hemorrhage were divided into edema enlargement group and edema non-enlargement group according to whether cerebral edema enlargement occurred.Clinical data of the patients were collected,and the MTHFR C677T genotype was detected.Results The level of homocysteine(Hey),vascular endothelial growth factor(VEGF)level at 72 h after admission,blood loss and incidence of venous thrombosis of lower extremity in edema enlargement group were significantly increased than those in edema non-enlargement group(P＜0.05-0.01).The frequency of TT genotype of MTHFR C677T in edema enlargement group was significantly higher than that of CT genotype,and the frequency of CT genotype was significantly higher than that of the frequency of CC genotype(all P＜0.05).There were significant differences in MTHFR C677T genotype and allele frequency between edema enlargement group and edema non-enlargement group(X2=70.668,P＜0.001;x2=84.139,P＜0.001).Multivariate Logistic regression analysis showed that VEGF level at 72 h after admission,MTHFR C677T CT genotype and TT genotype were independent risk factors for cerebral hemorrhage edema enlargement(OR=1.013,95％CI:1.007-1.019,P＜0.001;OR=5.534,95％CI:2.426-12.625,P＜0.001;OR=33.088,95％CI:9.012-121.479,P＜0.001).After adjusting for other factors,the OR of MTHFR C677CT to MTHFR C677CC was 5.53(95％CI:2.426-12.625,P＜0.05),and the OR of MTHFR C677TT to MTHFR C677CC was 33.09(95％CI:9.012-121.479,P＜0.05).The edema growth rate of TT genotype,CT genotype and CC genotype at MTHFR C677T site was significantly different(F=3.204,P=0.044).There was no significant difference in VEGF level among TT genotype,CT genotype and CC genotype of MTHFR C677T site at admission(F=0.978,P=0.379),but there was significant difference in VEGF level at 72 h after admission(F=5.819,P=0.007).Conclusion MTHFR C677T gene polymorphism is associated with secondary edema enlargement after intracerebral hemorrhage.
