塔克罗利斯 (Tac) 度/剂量 (C/D) 比率可以预测移植后的功能. 通过较低的C/D比率识别的快速代谢者,显示功能较差,表明潜在的毒性.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 药理学 药理学是指药理学的学科.
- 移植 移植 移植 移植
背景情况:
- 塔克罗利木斯 (Tac) 是一种氨酸抑制剂,具有可变的口服吸收和第一通代谢.
- 由于其狭窄的治疗窗口,由于个体的变化,需要对治疗药物进行监测.
- 评估Tac代谢率对于优化免疫抑制和患者的治疗结果至关重要.
研究的目的:
- 通过度/剂量 (C/D) 比率定义的Tacrolimus (Tac) 代谢率与移植后 (RTx) 功能之间的关联.
- 确定Tac C/D比是否可以作为RTx患者毒性早期指标.
主要方法:
- 40名RTx患者的回顾性观察性研究.
- 移植后1,3,6和12个月分析了塔克罗利斯 (Tac) 剂量和血液水平,以计算C/D比率.
- 患者被分为快速 (<1.05 ng/mL x 1/mg) 或慢 (>1.05 ng/mL x 1/mg) 的Tac代谢器. 血清肌素水平进行了比较,并与C/D比率相关.
主要成果:
- 快速的塔克罗利马斯 (Tac) 代谢剂显著增加了血清肌素水平 (P < 0.05).
- 在Tac C/D比率和血清肌水平之间观察到显著的相关性.
- 三个月后接受器运行特征 (ROC) 分析显示,用于识别快速代谢者的面积为0.925 (P < 0.01).
结论:
- 塔克罗利斯 (Tac) 度/剂量 (C/D) 比率是评估移植后 (RTx) 功能的一个有价值的工具.
- 塔克C/D比可以作为早期诊断标记,预测RTx接受者的毒性发展.
- 通过C/D比率监测Tac代谢有助于优化免疫抑制疗法和预防损伤.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
