摘要
目的:探讨大剂量甲氨蝶呤应用于血液系统疾病中的血药浓度与患者病理生理状态的关系,发现影响药物体内消除的因素,为甲氨蝶呤群体药动学研究提供线索。并统计不良反应,为临床安全应用大剂量甲氨蝶呤提供依据。方法:收集2014年1月至2016年2月共1 050例甲氨蝶呤血药浓度监测结果,全面收集病例信息,分析血药浓度与年龄、体重指数、给药剂量、输注时间、肝肾功能、尿量、尿pH、白蛋白等因素的关系,并汇总分析不良反应发生情况。结果:1 050例甲氨蝶呤血药浓度的检测结果中,停药后20h血药浓度651例(占62.00%)<1.0μmol·L^(-1),312例(占29.71%)在1~5μmol·L^(-1),87例(占8.29%)≥5.0μmol·L^(-1)。结论:患者的年龄、体质量指数、给药剂量、输注时间、尿量、总胆红素水平、肌酐清除率以及白蛋白水平对血药浓度分布的影响具有统计学意义,而丙氨酸氨基转移酶水平、尿p H值对于血药浓度分布的影响没有统计学显著性。
Objective: To study the relationship between serum methotrexate concentration and pathophysiological status during high--dose methotrexate treatment for hematological diseases. To provide evidences for population pharmacokinetics study by analyzing the influences of drug elimination, with offering the clinic with adverse reactions statistics. Methods: Data of 1 050 serum methotrexate concentration and the details of cases from Jan.2014 to Feb.2016 were collected. The relationship between serum methotrexate concentration and factors was analyzed, such as age, BWI, dose, infusion lasting time, hepatic and renal function, urine volume, urine pH, serum albumin level, and adverse reactions. Results: Among 1050 cases of Methotrexate serum concentrations, 651(62.00%) within 〈1.0μmol·L^-1, 312(29.71%)within 1-5μmol·L^-1, 87(8.29%) whithin ≥ 5.0μmol·L^-1. Conclusion: Age, BMI, doses, infusion lasting time, urine volume, Tbil, CrC1, and ALB levels had significant effects on methotrexate serum concentrations, while effects of ALT levels, urine pH showed no statistically significance.
