| TITLE： | Influential factors of voriconazole trough concentration and AUC in pediatric patients with thalassemia undergoing hematopoietic stem cell transplantation |
| 摘要： | 目的 分析地中海贫血患儿造血干细胞移植（HSCT）术后伏立康唑（VRZ）谷浓度（cmin）和药时曲线下面积（AUC）的影响因素。方法选择2021年1月至2024年1月于我院接受HSCT并使用VRZ预防或治疗侵袭性真菌感染的地中海贫血患儿60例，采用高效液相色谱法测定VRZ的血药浓度并计算AUC；采用多元线性回归分析影响VRZcmin、AUC的独立因素。结果共得到60例患儿的120例次VRZcmin，26例患儿的27例次VRZAUC。VRZcmin的中位浓度是0.31mg/L，其中0.5～5mg/L有46例次（38.33%），＞5mg/L有2例次（1.67%），＜0.5mg/L有72例次（60.00%）；VRZAUC的中位数是11.68mg·h/L。患儿体重、HSCT术后时间、淋巴细胞计数以及是否合用苯妥英钠、他克莫司、环孢素对VRZcmin有显著影响（P＜0.05）；淋巴细胞计数和是否合用苯妥英钠对VRZAUC有显著影响（P＜0.05）。结论患儿体重、HSCT术后时间、淋巴细胞计数以及是否合用苯妥英钠、他克莫司、环孢素是影响VRZcmin的独立因素，淋巴细胞计数、是否合用苯妥英钠是影响VRZAUC的独立因素。 |
| ABSTRACT： | OBJECTIVE To analyze the influential factors on trough concentration （cmin） and area under the drug concentration time curve （AUC） of voriconazole （VRZ） in pediatric patients with thalassemia undergoing hematopoietic stem cell transplantation （HSCT）. METHODS A total of 60 pediatric patients with thalassemia undergoing HSCT who used VRZ for prevention or treatment of invasive fungal infection were collected in our hospital from January 2021 to January 2024. The plasma concentration of VRZ was measured by high-performance liquid chromatography and the AUC was calculated. The factors affecting cmin and AUC of VRZ were analyzed using multiple linear regression. RESULTS A total of 120 cases of VRZ cmin in 60 pediatric patients was obtained and 27 cases of VRZ AUC in 26 pediatric patients were obtained. The median concentration of VRZ cmin was 0.31 mg/L； 46 cases had a cmin in 0.5-5 mg/L（ 38.33%）， 2 cases had a cmin＞5 mg/L（ 1.67%）， and 72 cases had a cmin＜0.5 mg/L. The median AUC of VRZ was 11.68 mg·h/L. The patient’s body weight， HSCT postoperative days， lymphocyte count， and combined use of phenytoin sodium， tacrolimus or cyclosporine had significant effects on VRZ cmin （P＜0.05）. Lymphocyte count and combined use of phenytoin sodium had significant effects on VRZ AUC （P＜0.05）. CONCLUSIONS The body weight， HSCT postoperative days， lymphocyte count， and combined use of phenytoin sodium， tacrolimus or cyclosporine are independent factors affecting VRZ cmin. Lymphocyte count and combined use of phenytoin sodium are independent factors affecting VRZ AUC. |
