摘要:

目的: 检测并分析患者神经与精神用药相关药物基因多态性,探讨神经与精神用药基因检测的临床价值,为精准用药提供依据。方法: 使用基质辅助激光解吸电离飞行时间质谱(MALDI-TOF-MS)技术,对安徽医科大学第二附属医院心理与睡眠医学科2024年2月至2024年9月入院的36例患者进行神经与精神类药物相关基因检测,并对相关药物代谢酶基因(CYP2D6和CYP2C19)和作用靶点基因(FKBP5、SACM1L、MDGA2、HTR1A和HTR2A)多态性进行分析。根据基因多态性结果,进行精准用药分析。结果: 36例患者中,药物代谢酶基因CPY2D6*4基因突变频率最低,为0.00%,CYP2C19*2基因突变的频率最高,为44.4%;相关药物作用靶点基因多态性中,MDGA2的AC基因型频率最高(38.3%),SACM1L的GG基因型频率最高(63.8%),FKBP5的GG基因型频率最高(61.1%),HTR1A的CG和GG基因型频率最高(均为47.2%),HTR2A的GG基因型频率最高(55.6%);CYP2D6*10/*10型和CYP2C19*2/*2型患者的药物代谢/清除可能降低,建议降低药量,定期进行血药浓度监测。结论: 神经与精神用药基因多态性与患者对相关药物的反应性密切相关,根据神经与精神用药基因检测结果为患者提供精准用药指导具有临床应用价值。

Abstract:

AIM: To detect and analyze the polymorphism of related drug genes in patients treated with neurological and psychiatric drugs, and to explore the clinical value of gene detection for neurological and psychiatric drugs, so as to provide basis for precision drug use. METHODS: Stroma-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was employed to detect genes related to neurological and psychiatric drugs in 36 patients admitted to the department of psychology and sleep medicine at the second affiliated hospital of Anhui medical university between February 2024 and September 2024. The polymorphisms of drug-metabolizing enzyme genes (CYP2D6 and CYP2C19) and target genes (FKBP5, SACM1L, MDGA2, HTR1A, and HTR2A) were analyzed. Based on the results of gene polymorphism, precision drug use analysis was conducted. RESULTS: Among the 36 patients, the mutation frequency of the CYP2D6*4 gene was the lowest at 0.00%, while that of the CYP2C19*2 gene was the highest at 44.4%. Regarding drug target gene polymorphisms, the AC genotype of MDGA2 had the highest frequency at 38.3%, the GG genotype of SACM1L was the most frequent at 63.8%, and the GG genotype of FKBP5 was prevalent at 61.1%. Additionally, the CG and GG genotypes of HTR1A both had the highest frequencies at 47.2%, and the GG genotype of HTR2A was the most common at 55.6%. For patients with the CYP2D6*10/*10 and CYP2C19*2/*2 genotypes, drug metabolism and clearance may be reduced. It is recommended to lower the dose and regularly monitor blood drug concentration in these patients. CONCLUSION: The polymorphism of genes related to neurological and psychotropic drugs is closely linked to patients' responses to these medications. Providing precision medication guidance based on genetic testing results for these drugs holds significant clinical value.
