    • 摘要: Objective To evaluate the correlation and difference of reversed phase high performance liquid chromatography (RP-HPLC) and fluorescence polarization immunoassay (FPIA) on determining serum concentration of carbamazepine.Methods Fifty serum samples were collected,both RP-HPLC and FPIA methods were employed to determine the concentration of carbamazepine.The results were analyzed by paired t test,Bland-Altman and Deming regression methods,respectively.Results The results of measuring 50 samples by the two methods showed that FPIA datas were significantly higher than RP-HPLC datas,and there was statistically significant difference(P<0.05) and poorer consistency between two methods;There was good correlation between carbamazepine concentrations determined by the two methods.Deming regression equation was CFPIA=1.195 3 CRP-HPLC-0.144 0,and Pearson correlation coefficient was 0.968 5.Conclusion Clinicians should pay more attention to the difference of carbamazepine concentration determination by different methods when carbamazepine individualized dosage regimen was adjusted according to therapeutic drug monitoring.%目的 比较反相高效液相色谱(RP-HPLC)法与荧光偏振免疫(FPIA)法测定血浆卡马西平浓度的差异性和相关性.方法 收集卡马西平血浆样本50例,分别采用RP-HPLC和FPIA进行测定,采用配对t检验比较两者均数的差异;Bland-Altman进行一致性分析;Deming回归法进行相关性分析.结果 FPIA法的测定结果高于RP-HPLC法,两种测定方法均数之间差异有统计学意义(P<0.05),一致性较差;Deming回归分析显示两种方法之间存在良好的相关性,回归方程为:CFPIA=1.195 3CRP-HPLC-0.144 0,Pearson相关系数为0.968 5.结论 在制定卡马西平个体化给药方案时应充分考虑不同检测方法的影响,正确解读检测结果,提高个体化用药水平.

    • 摘要: Objective: To establish an HPLC and LC-MS/MS method for determining vancomycin in human serum and to compare with FPIA. Methods: Serum samples for HPLC were extracted by sedimentation with 10% perchloric acid. The chromatographic column of NovaPak C18 was used and the column temperature was kept at 35°C. The mobile phase was composed of KH2PO4 buffer solution-methanol (85∶15, v/v, pH=3.2), the flow rate was 1 mL·min-1 and the UV detection was performed at 230 nm. Serum samples for LC-MS/MS were precipitated by acetonitrile and the supernatants were used. The separations were performed on an Agilent Eclipse XDB-C18 analytical column (100 mm×2.1 mm, 3.5μm) at 40°C with the mobile phase composed of water (0.1% formic acid)-acetonitrile (90∶10, v/v) at a flow rate of 0.2 mL· min-1. ESI was used which was performed in the multiple reaction monitoring mode (MRM) using target ions m/z 725.0→144.0 (vancomycin) and m/z 718.5→144.0 (IS). Then the HPLC and LC-MS/MS methods were used to determine 95 clinical samples comparing with FPIA. Results: The linear range of the two methods were 0.4~96 and 1.2~96μg·mL-1, respectively, with LLOQ at 0.4 and 1.2μg·mL-1. The intra-and inter-day RSD were within 15%. The HPLC and LC-MS/MS methods strongly correlated with FPIA without significant differences. Conclusion: The HPLC and LC-MS/MS methods we established were rapid, sensitive, precise and reliable for the determination of vancomycin in human serum, which can be applied in the study of human vancomycin pharmacokinetics and the practice of therapeutic drug monitoring.%目的:建立HPLC法和液相色谱-串联质谱(LC-MS/MS)法检测人血浆中万古霉素的浓度,并分别与FPIA法进行比较。方法:HPLC法:100μL血浆样品加入等体积10%的高氯酸沉淀,振荡离心后取上清液进样。采用Agilent Eclipse XDB-C18(250 mm×4.6 mm,5μm),柱温为35°C,流动相为0.05 mol·L-1 KH2PO4(pH=3.2)-甲醇(74∶26,v/v),流速为1 mL·min-1,检测波长为230 nm。 LC-MS/MS法:100μL血浆样品用300μL乙腈沉淀,振荡离心后取上清液进样。色谱柱为Agilent Eclipse XDB-C18(100 mm ×2.1 mm,3.5μm),柱温为40°C,流动相为水(含0.1%甲酸)-乙腈(90∶10,v/v),流速为0.20 mL·min-1。采用电喷雾化离子源(ESI),多离子反应模式(MRM)检测,万古霉素和内标去甲万古霉素的监测离子对分别为m/z 725.0→144.0和718.5→144.0。采用建立的HPLC法和LC-MS/MS法测定95份临床样本,并与FPIA法进行相关性和测定方法的偏倚分析。结果:HPLC法和LC-MS/MS法测定万古霉素的线性范围分别为1.2~96μg·mL-1和0.4~96μg·mL-1,低、中、高三种浓度质控品日内和日间相对标准差(RSD)均<15%。两种方法与FPIA法有很强的相关性(r=0.9621,P<0.0001和r=0.9466,P<0.0001),无明显偏倚。结论:建立的HPLC和LC-MS/MS法快速、灵敏、准确,样本测定结果与FPIA法无显著差异,适用于万古霉素的常规血药浓度监测及人体药物代谢动力学研究。
