Relationship between Multidrug Resistance Gene ABCB1 C3435T Gene Polymorphism and Serum Concentration of Levetiracetam in Children with Epilepsy in Xinjiang / 中国药学杂志

ABSTRACT

OBJECTIVEP: To explore the relationship between multidrug resistance gene ABCB1 C3435T gene polymorphism and serum concentration, clinical efficacy and adverse reactions of levetiracetam (LEV) in children with epilepsy in Xinjiang. METHODS: The serum concentration of 116 children with epilepsy of in Xinjiang were collected and determined by oral LEV. The ABCB1 C3435T genotype was detected by polymerase chain reaction-fluorescence staining in situ hybridization. The correlation between ABCB1 C3435T gene polymorphism and serum concentration, clinical efficacy and adverse reactions was analyzed. RESULTS: The C and T allele frequencies of ABCB1 C3435T in children were significantly different (χ2=12.520, P0.05). The clinical effective rate of CT type was higher than that of CC type and TT type, and the incidence of adverse reactions of TT type was higher than that of CC type and CT type. There were significant differences in clinical efficacy and adverse reactions among CC type, CT type and TT type (χ2=12.870,P<0.01; χ2=19.292, P<0.01). CONCLUSION: ABCB1 C3435T gene polymorphism may has a effect on the serum concentration, clinical efficacy and adverse reactions of LEV in children with epilepsy in Xinjiang.
