Abstract

This study aims to describe the distribution characteristics of voriconazole (VRC) plasma trough concentrations (Ctrough) in patients with liver dysfunction, identify factors influencing VRC Ctrough, and provide recommendations for the use of VRC in this population. We retrospectively collected medical records of hospitalized patients with liver dysfunction who used VRC and underwent therapeutic drug monitoring (TDM) at the First Hospital of Changsha. The severity of liver dysfunction was assessed by the Child-Pugh (CP) score. Multiple linear regression was employed to explore factors affecting VRC Ctrough in these patients. A total of 147 Ctrough from 102 patients with liver dysfunction were analyzed. Patients were categorized into a control group (n = 40), CP-A (n = 39), CP-B (n = 11), and CP-C group (n = 12). The initial probability of target attainment of Ctrough was 70.6%, with 6.9% of patients obtaining subtherapeutic Ctrough and 22.5% obtaining supertherapeutic Ctrough. The initial Ctrough in CP-A and B were 5.05 (0.64-9.57) mg/L and 5.37 (0.26-10.01) mg/L, respectively, significantly higher than the control group (P = 0.021 and P = 0.010). The proportion of VRC Ctrough of >5.5 mg/L in CP-A and B was 33.3% and 45.5%, respectively. Multiple linear regression analysis revealed that factors such as age ≥70 years, CP class, C-reactive protein (CRP), and direct bilirubin were significantly related to the initial VRC Ctrough. Among all measurements, patients with severe inflammation (CRP >100 mg/L), aged ≥70 years, and albumin levels of <30 or <25 g/L had significantly higher VRC Ctrough. The treatment success rate of VRC was 69.6% (71 of 102), and the rate of VRC-related adverse drug reactions was 29.4% (30 of 102). The recommended half-maintenance dose may lead to elevated VRC Ctrough in patients with CP-A and CP-B. TDM is essential for patients with advanced age, severe infections, or hypoalbuminemia to prevent excessive VRC trough levels.

肝功能异常患者的治疗药物监测和伏立康唑的安全性。
本研究旨在描述肝功能异常患者体内伏立康唑(VRC)血浆谷浓度(Ctrough)的分布特征,确定影响伏立康唑Ctrough的因素,并为该人群使用伏立康唑提供建议。我们回顾性地收集了在长沙市第一医院住院的肝功能异常患者的病历,这些患者使用了 VRC 并接受了治疗药物监测(TDM)。肝功能异常的严重程度通过Child-Pugh(CP)评分进行评估。采用多元线性回归探讨影响这些患者 VRC Ctrough 的因素。共分析了 102 名肝功能异常患者的 147 个 Ctrough。患者被分为对照组(40 人)、CP-A 组(39 人)、CP-B 组(11 人)和 CP-C 组(12 人)。最初达到目标 Ctrough 的概率为 70.6%,其中 6.9% 的患者获得了亚治疗 Ctrough,22.5% 的患者获得了超治疗 Ctrough。CP-A 组和 B 组的初始 Ctrough 分别为 5.05 (0.64-9.57) mg/L 和 5.37 (0.26-10.01) mg/L,明显高于对照组(P = 0.021 和 P = 0.010)。CP-A 组和 B 组 VRC Ctrough >5.5 mg/L 的比例分别为 33.3% 和 45.5%。多元线性回归分析显示,年龄≥70 岁、CP 分级、C 反应蛋白(CRP)和直接胆红素等因素与初始 VRC Ctrough 显著相关。在所有测量指标中,炎症严重(CRP>100 mg/L)、年龄≥70 岁、白蛋白水平低于 Ctrough 的患者的治疗成功率最高。VRC 的治疗成功率为 69.6%(102 例中有 71 例),与 VRC 相关的药物不良反应发生率为 29.4%(102 例中有 30 例)。推荐的半维持剂量可能会导致 CP-A 和 CP-B 患者的 VRC Ctrough 升高。对于高龄、严重感染或低白蛋白血症患者,TDM 对防止 VRC 谷值水平过高至关重要。
