Abstract:
OBJECTIVE To provide a reference for the dose adjustment of tacrolimus in patients who underwent lung transplantation after combined use of voriconazole. METHODS The clinical data of lung transplantation patients who used voriconazole and tacrolimus in our hospital from January 2020 to December 2022 were collected retrospectively. The effects of voriconazole on the valley concentration， daily dose and standardized blood concentration of tacrolimus were analyzed by using SPSS 21.0 software； multiple linear regression analysis was conducted for the factors that may affect the standardized blood concentration of tacrolimus. RESULTS A total of 153 lung transplantation patients were included. After the combination of voriconazole， the average daily dose of tacrolimus decreased from 3.37 mg to 0.76 mg， and valley concentration and standardized blood concentration were increased significantly （P＜0.000 1）. The average daily dose of voriconazole was negatively correlated with the standardized blood drug concentration of tacrolimus （P＝0.000 1，r＝－0.224）. The valley concentration of voriconazole was positively correlated with valley concentration （P＜0.000 1，r＝0.316） and standardized blood concentration （P＜0.000 1，r＝ 0.249） of tacrolimus. After combination with voriconazole， the standardized blood drug concentration of patients who underwent single lung transplantation was significantly higher than those who underwent double lung transplantation， and the standardized blood concentration of tacrolimus after oral administration of voriconazole was significantly higher than after intravenous drip of voriconazole （P＜0.05）. Most liver and kidney function indicators showed no significant changes. The results of multiple factor regression analysis showed that the valley concentration of voriconazole had a significant impact on the standardized blood concentration of tacrolimus （P＜0.001）. CONCLUSIONS The valley concentration of voriconazole has greatest influence on the blood concentration and dose adjustment of tacrolimus， which is an independent influencing factor. In clinical practice， the dose of tacrolimus should be reduced in combination with voriconazole， and therapeutic drug monitoring should be conducted for both drugs.
