Effects of Cerebrospinal Fluid AMPA Receptor Levels on the Clinical Efficacy of Lamotrigine in the Treatment of Epilepsy

Abstract

Background ：Epilepsy is one of great health burden in the world, deeply effects epilepsy population’s mental and physical health,some can totally recover through effective treatment, while some others are difficult to recover even have life risks when seizure attacks. In that case,we explore the effects of cerebrospinal fluid AMPA receptor levels on the clinical efficacy of lamotrigine in the treatment of epilepsy.We believe our work might have an implication in the treatment of epilepsy. Methods ：The 70 cases of epilepsy in our hospital were diagnosed and selected in this study from December 2016 to October 2018; The AMPA receptor content of patients in cerebrospinal fluid were determined by enzyme linked immunosorbent assay; The patients were paired into high AMPA group (n=34) and low AMPA group (n=36) according to the median value at 4.08 ng/ml. Clinical efficacy and the incidence of adverse reactions were compared between two groups. Results ：Before treatment, there was no significant difference in seizure frequency between the two groups (P>0.05); After treatment for 6 months and 12 months, the seizure frequencies of the two groups were gradually reduced (P<0.05); Moreover, the number of seizures in the low AMPA group were significantly less than those in the high AMPA group (P<0.05); The response rate of high AMPA group was 79.41%, which was significantly lower than that in the low group AMPA (χ2=6.055, P=0.048); The improvement on the efficiency of electroencephalogram in the high AMPA group was 67.65%, which was significantly lower than that in the low AMPA group (χ2=4.686, P=0.030); However, there was no significant on the incidence of adverse reactions between two groups (χ2=0.202, P=0.653). Conclusions： AMPA receptor plays an important role in the development of epilepsy and the low AMPA receptor level patients were more efficacies to the treatment of lamotrigine.
