摘要

目的:抗精神病药物的治疗药物监测(TDM)有助于优化治疗方案,解释不良反应或无反应。治疗失败或不良反应的一个原因是由细胞色素P450药物代谢基因的遗传变异引起的。本研究的目的是评估CYP2D6多态性对CYP2D6代谢的抗精神病药物稳态血清浓度的影响,同时考虑与CYP2D6抑制剂共用药。方法:采集82例精神病患者血清和EDTA样本。在液-液萃取后,使用超高高效液相色谱-串联质谱(UHPLC-MS/MS)方法分析血清样本,以定量抗精神病药物。使用Luminex xTAG(R) CYP2D6 Kit v3 (Luminex Corporation)进行CYP2D6基因分型。通过计算活动评分(AS)将患者分为5个表型亚组:代谢不良者(PM;AS 0),中间代谢产物(IM;AS 0.5-1),活性较慢的广泛代谢物(EM-s;AS 1-1.5),具有快速活性的广泛代谢物(EM-f; AS 2), and ultra-rapid metabolizers (UM; AS >2). The influence of the phenotypes on the concentration-to-dose and metabolite-to-parent ratios was evaluated. RESULTS: Overall, 6.1 % UM (n = 5), 25.6 % EM-f (n = 21), 46.3 % EM-s (n = 38), 1.2 % EM-s/EM-f (n = 1), 6.1 % IM (n = 5), and 14.6 % PM (n = 12) were found, taking co-administration of strong and moderate CYP2D6 inhibitors into account (phenoconversion). It was demonstrated that CYP2D6 polymorphisms affect the serum concentrations of aripiprazole (n = 18), haloperidol (n = 11), risperidone (n = 20), and zuclopenthixol (n = 6), while no influence was seen on the paliperidone serum concentrations (n = 31). CONCLUSIONS: Even with a small number of patients per antipsychotic, the importance of CYP2D6 genotyping was still clearly stated. This study illustrates the high potential of combining TDM and CYP2D6 genotyping in clinical practice.
