Objective To investigated the influence of the CYP2C9 polymorphism on lipid profile and blood concentration in epileptic children with VPA. Methods This study collected the information of healthy children and epilepsy children who were treated with VPA in the First Affiliated Hospital of Putian University during June, 2018 to March, 2021. The serum lipids of 184 cases were collected and compared between epilepsy group before and after treatment with VPA with the control group. The polymorphism of CYP2C9 gene in children with epilepsy was detected, and lipid and VPA concentration were compared after classification. Results There was no significant difference in lipid between the control group and the epilepsy group before treatment (P>0.05); The TC, HDL, LDL, TC/HDL, LDL/HDL were statistically different in VPA treatment group from the control group (P<0.05), and there were statistical differences in TG, LDL, TC/HDL, LDL/HDL between the trial group before the initiation and VPA treatment (P<0.05); There is no correlation between VPA blood concentration and lipid (P>0.05). VPA concentration, TC, HDL, LDL, TC/HDL and LDL/HDL in CYP2C9 wild-type were statistically different from heterozygous mutant. Conculsions CYP2C9 polymorphism and long-term use of VPA caused the changes in serum lipid levels in epilepsy children.
Objective To study the correlation of changes in liver function during long-term treatment with sodium valproate (VPA) in children with epilepsy in Putian, and to explore individualized administration to improve the compliance of children with medication. Methods The blood concentration of VPA and related biochemical test data of 350 children with epilepsy from June 1, 2018 to March 1, 2021 were collected in our hospital. According to the results of VPA blood concentration, they were classified as low Blood concentration group (<50 μg/mL), therapeutic blood concentration group (50 ~ 100 μg/mL) and high blood concentration group (>100 μg/mL). Results There was no significant difference in liver function indexes between the VPA treatment group and the control group (P>0.05). There were significant differences in liver function ALT, AST, AST/ALT, TBIL and DBIL among the groups of VPA blood concentration range (P<0.05). The abnormal incidence of liver function indexes of high blood drug concentration was lower in the concentration group and higher in the treatment concentration group, and there were differences (P<0.05). Conclusion Abnormal liver function in the high blood drug concentration treatment groupis quite common, and the dose of the drug should be adjusted in time to avoid liver damage caused by the VPA.
