摘要:

文题释义:

超高效液相色谱-串联质谱法:是一种将超高效液相色谱的高效分离能力与串联质谱的高灵敏度、高选择性检测能力相结合的分析技术。相比传统高效液相色谱法,超高效液相色谱法使用更小粒径(< 2 μm)的色谱柱填料,可在更高压力下工作,分析时间缩短3-10倍,灵敏度提高2-5倍。
万古霉素血药浓度:万古霉素是时间依赖性抗生素,其疗效与血药浓度超过最低抑菌浓度的时间相关。临床主要监测谷浓度(下次给药前30 min的血药浓度),是评价疗效和安全性的关键指标。对于骨科感染等严重感染,推荐谷浓度维持在10-20 μg/mL,既能保证疗效又能降低肾毒性风险。谷浓度< 10 μg/mL易产生耐药,> 20 μg/mL肾毒性明显增加。

摘要
背景:万古霉素作为治疗耐甲氧西林金黄色葡萄球菌感染的一线药物,在骨科围术期预防和治疗感染中应用广泛,但其治疗窗窄、个体差异大的特点使得血药浓度监测成为确保疗效和安全性的关键。
目的:建立超高效液相色谱-串联质谱测定血浆中万古霉素浓度的方法,并探讨血药浓度变化与临床疗效及急性肾功能损害的相关性。
方法:选择2020年1月至2022年5月在北京积水潭医院贵州医院住院的200例骨科感染患者,采用超高效液相色谱-串联质谱法测定万古霉素血药浓度,监测肾功能指标(血肌酐、尿素氮),分析万古霉素不同血药浓度水平患者的临床疗效和急性肾功能损害发生情况。
结果与结论:①建立的超高效液相色谱-串联质谱方法线性范围为0.5-120.0 μg/mL(R²=0.997),日内相对标准偏差为4.82%-6.57%,日间相对标准偏差为10.2%-12.3%,准确度为97.3%-106%;②万古霉素血药浓度10-20 μg/mL组临床有效率(82%)显著高于< 10 μg/mL组(67%)(P < 0.05);③万古霉素血药谷浓度> 20 μg/mL组肾功能损害发生率(35.0%)显著高于10-20 μg/mL组(16.0%)和< 10 μg/mL组(6.7%)(P < 0.05);④提示建立的超高效液相色谱-串联质谱方法灵敏准确,可用于临床万古霉素血药浓度监测;维持万古霉素血药浓度在10-20 μg/mL范围内可获得最佳临床疗效并降低肾毒性风险,血药浓度监测对指导个体化给药具有重要意义。

Abstract: BACKGROUND: Vancomycin is widely used as a first-line drug for treating methicillin-resistant Staphylococcus aureus infections in orthopedic perioperative infection prevention and treatment. However, its narrow therapeutic window and large individual differences make blood drug concentration monitoring crucial for ensuring efficacy and safety.
OBJECTIVE: To establish the ultra-performance liquid chromatography-tandem mass spectrometry method to determine the concentration of vancomycin in plasma, and explore the correlation of blood drug concentration changes with clinical efficacy and acute renal impairment.
METHODS: Totally 200 orthopedic patients with bone infection who were hospitalized in Beijing Jishuitan Hospital Guizhou Hospital from January 2020 to May 2022 were selected. Blood drug concentration was measured by ultra-performance liquid chromatography-tandem mass spectrometry. Renal function indexes (blood creatinine and urea nitrogen) were monitored, and the clinical efficacy and acute renal impairment of patients with different blood drug concentration levels were analyzed. 
RESULTS AND CONCLUSION: (1) The established ultra-performance liquid chromatography-tandem mass spectrometry method showed a linear range of 0.5-120.0 μg/mL (R²=0.997), with an intra-day relative standard deviation of 4.82%-6.57%, an inter-day relative standard deviation of 10.2%-12.3%, and an accuracy of 97.3%-106%. (2) The clinical effective rate in the group with a blood drug concentration of 10-20 μg/mL (82%) was significantly higher than that in the group with a blood drug concentration of < 10 μg/mL (67%) (P < 0.05). (3) The incidence of renal function impairment in the group with a trough blood drug concentration of > 20 μg/mL (35.0%) was significantly higher than that in the 10-20 μg/mL group (16.0%) and the < 10 μg/mL group (6.7%) (P < 0.05). (4) It is suggested that the established ultra-performance liquid chromatography-tandem mass spectrometry method is sensitive and accurate, and can be used for clinical monitoring of vancomycin blood concentration. Maintaining the blood drug concentration within the range of 10-20 μg/mL can achieve the best clinical efficacy and reduce the risk of nephrotoxicity. Monitoring blood drug concentration is of great significance for guiding individualized drug administration.
