ABSTRACT
Objective To explore the serum levels of progestrone (Prog) and dehydroepiandrosterone sulfate(DHEAS),and the effect of sodium valproate(VPA) and lamotrigine(LTG) on the levels of Prog and DHEAS in infantile spasms.Methods A total of 36 cases of infantile spasms (spasms group) before treatment and 40 cases health infants(control group) were detected the serum Prog and DHEAS levels by electrochemiluminescence immunoassay,and were compared with 21 cases receiving monotherapy with VPA(VPA group),and 13 cases receiving therapy plus lamotrigine(LTG group) before and 4 months after treatment to observe the changes of sex hormone.Results There were no significant differences in Prog and log(DHEAS) (logarithmic transformation) levels between spasms group and control group (P ＞0.05).The serum Prog level of baby girls and baby boys were lower after treatment than those before treatment in VPA group respectively (t =2.603,3.146 ; P =0.003,0.008,respectively).The log (DHEAS) level of baby girls and baby boys were higher in LTG group after treatment than those before treatment respectively(t =3.185,2.663 ;P =0.007,0.041).Conclusion Infantile spasms would not influence the hormone metabolism,while VPA and LTG can influence the sex hormone.The hormone level should be monitored in the treatment.
ABSTRACT
Objective To investigate the association between multi-drug resistant 1 (MDR1) gene C3435T and T129C polymorphism with refractory epilepsy in children. Methods A total of 260 children including 60 refractory epilepsy, 100 drug-responsive epilepsy, and 100 healthy children were enrolled. The genotypes for MDR1 polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism analysis.The distribution of genotypes and allele frequencies of the three groups were compared. Results The distribution of TT/TC/CC genotypes and T/C allele frequencies of C3435T showed no signiifcant difference between drug-resistant patients and drug-responsive patients or normal control group (P>0.05). Drug-resistant patients were more likely to have the TC genotype and the C allele at T129C when compared with the drug-responsive patients and the normal control group (P<0.05). Conclusions T129C polymorphism of the MDR1 gene was associated with refractory epilepsy in children.
