摘要:

目的 建立基于同位素稀释液相色谱串联质谱法(ID LC-MS/MS)的血清奥卡西平(OXC)、10-羟基卡马西平(MHD)候选参考测量程序,并进行性能评估。方法 分别以OXC-2H4、MHD-2H4 为内标,采用蛋白沉淀法(PPT)对样本进行前处理。色谱采用Phenomenex Kinetex F5色谱柱,流动相为0.1%甲酸水-0.1%甲酸甲醇,梯度洗脱;质谱采用正离子多反应监测(MRM)模式。对方法的线性、定量限(LOQ)、基质效应、正确度、精密度、稳定性、不确定度进行评估,并与临床实验室常规检测系统(LC-MS/MS)进行比较。结果 ID LC-MS/MS测定血清OXC、MHD的线性范围为0.02~50.00 μg·mL-1,定量限为0.015 μg·mL-1。OXC的相对基质效应为-2.09%~2.12%,加标回收率为100.00%~101.62%。MHD的相对基质效应为-0.87%~2.99%,加标回收率为101.39%~102.08%。OXC和MHD的批内、批间变异系数(CV)均<3%,相对扩展不确定度≤2.57%。2种方法检测血清OXC、MHD的结果具有良好的相关性。采用经候选参考测量程序校准后的常规检测系统检测2024年全国血清治疗药物监测室间质量评价计划5个浓度血清样本,偏倚为0.00%~3.64%。结论 成功建立了基于ID LC-MS/MS的血清OXC、MHD候选参考测量程序,可用于OXC、MHD药物浓度监测(TDM)项目的标准化。

Abstract:

Objective To establish a candidate reference measurement procedure for serum oxcarbazepine (OXC) and 10-hydroxy carbamazepine (MHD) using isotope dilution liquid chromatography-tandem mass spectrometry (ID LC-MS/MS),and to evaluate its performance. Methods The samples were pre-treated using protein precipitation (PPT) with OXC-2H4 and MHD-2H4 as internal standards. The chromatography used a Phenomenex Kinetex F5 column,with a mobile phase of 0.1% formic acid water -0.1% formic acid methanol and gradient elution;the mass spectrometry used positive ion multiple reaction monitoring (MRM) mode. The linearity,limit of quantification (LOQ),matrix effect,accuracy,precision,stability and uncertainty of the method were evaluated,which was compared with the routine determination system (LC-MS/MS) in clinical laboratories. Results The linear range of ID LC-MS/MS for serum OXC and MHD was 0.02-50.00 μg·mL-1,and the LOQ was 0.015 μg·mL-1. The relative matrix effect of OXC was -2.09%-2.12%,and the recovery rate was 100.00%-101.62%. The relative matrix effect of MHD was -0.87%-2.99%,and the recovery rate was 101.39%-102.08%. The within-run and between-run coefficients of variation(CV)of OXC and MHD were both <3%. The relative expanded uncertainty was ≤2.57%. The results of the 2 methods for determining serum OXC and MHD had good correlation. Using the routine determination system calibrated by the candidate reference measurement procedure to determine 5 serum samples with different concentrations from the 2024 National Serum Therapeutic Drug Monitoring Inter-laboratory Quality Evaluation Program,the deviation was 0.00%-3.64%. Conclusions A candidate reference measurement procedure for serum OXC and MHD based on ID LC-MS/MS was successfully established,which can be used for the standardization of OXC and MHD therapeutic drug monitoring (TDM) projects.
