ABSTRACT
Objective To explore the relationship between the overexpression of P glycoprotein (P GP) multidrug resistance (MDR) gene in the epileptic patient's peripheral blood lymphocytes and the drug resistance of the intractable epilepsy Methods This is a prospective, observational study. First, the overexpression of P GP MDR in 85 epileptic patients' (M 39, F46,overage age 24 years) peripheral blood lymphocytes were investigated by using immunocytochemistry (ICT) or flow cytometer (FCE). Then, patients were given a single or a combining of two antiepilepstic drugs which they did not received before (including carbamazepine, valproic acid, phenobarbitone,phenytoin), when the single drug was not effective in observing the clinical efficacy Results In FCE study group, results showed that the 11 patients with overexpression of P GP MDR in the epileptic patient's peripheral blood lymphocytes became tolerant to antiepileptic drugs. Eighteen out of 32 patients without overexpression of P GP MDR are effective. In the ICT study group, it is effective that there are only 2 out of the 22 patients with overexpression of P GP MDR. Seven of 12 patients without overexpression of P GP MDR are effective Conclusion It is suggested that the overexpression of MDR in the intractable epileptic patient's peripheral blood lymphocytes might be a significant drug resistance marker. The sensibility of ICT method should be better than the FCE,though the latter may be more accurate.
