Abstract
ObjectiveEdaravone is utilized in intra-cerebral hemorrhage (ICH) patients for years, while personalized variances were observed in clinic. To explore the precision medicine strategy for Edaravone, this study investigated the association between genetic polymorphisms and Edaravone efficacy in ICH patients. MethodsWe genotyped 7 SNPs in 4 potential genes, including COL4A2, TNF, WNK2 and IL6, from the peripheral blood of 217 ICH patients with or without Edaravone utilizations. PLINK and SPSS were utilized for association tests, Student's t tests, Mann-Whitney U tests and Chi-square tests. ResultsRs1800796 (C>G) in IL6 (OR: 0.41, 95 % CI: 0.18-0.94, p-value = 0.03) and rs16936752 (G>T) in WNK2 (OR: 0.28, 95 % CI: 0.09-0.88, p-value = 0.02) were found to be significantly associated with Edaravone efficacy. The association of rs1800796 and rs16936752 were found to be different in patients with or without smoking habit, alcohol drinking habit, hypertension history and hyperlipemia history were found to be different. Both of these two SNPs were found to be associated with the concentration of high-density lipoprotein cholesterol (HDL) in ICH patients. ConclusionsThe IL6 rs1800796 and the WNK2 rs16936752 could be useful biomarkers for prognosis prediction during Edaravone treatment. These SNPs should be considered in the personalized medicine strategy for Edaravone in the future.
