Abstract

Purpose: The purpose of this study was to evaluate the effect of UGT1A4 and UGT2B7 polymorphisms on the plasma concentration of lamotrigine in Chinese patients with bipolar disorder.

Methods: A total of 104 patients were included in this study. Steady-state plasma lamotrigine concentrations were determined in each patient after at least 21 days of continuous treatment with a set dose of the drug. Lamotrigine plasma concentrations were ascertained using ultra-performance liquid chromatography. Simultaneously, plasma samples were used for patient genotyping.

Results: The age, sex, BMI, daily lamotrigine dose, plasma lamotrigine concentration, and lamotrigine concentration/dose ratio of patients exhibited significant differences, and these were associated with differences in the genotype [ UGT1A4 -142T>G and UGT2B7 -161C>T ( P  < 0.05)]. Patients with the GG and GT genotypes in UGT1A4 -142T>G had significantly higher lamotrigine concentration/dose values (1.6 ± 1.1 and 1.7 ± 0.5 μg/ml per mg/kg) than those with the TT genotype (1.4 ± 1.1 μg/ml per mg/kg). Likewise, patients with the UGT2B7 -161C>T TT genotype had significantly higher lamotrigine concentration/dose values (1.6 ± 1.1 μg/ml per mg/kg) than those with the CC genotype (1.3 ± 1.3 μg/ml per mg/kg). Multiple linear regression analysis showed that sex, lamotrigine dose, UGT1A4 -142T>G, and UGT2B7 -161C>T were the most important factors influencing lamotrigine pharmacokinetics ( P  < 0.001).

Conclusion: The study results suggest that the UGT1A4 -142T>G and UGT2B7 -161C>T polymorphisms affect lamotrigine plasma concentrations in patients with bipolar disorder.

UGT1A4 和 UGT2B7 多态性对双相情感障碍患者拉莫三嗪血浆浓度的影响。
目的:本研究旨在评估 UGT1A4 和 UGT2B7 多态性对中国双相情感障碍患者拉莫三嗪血浆浓度的影响:本研究共纳入104例患者。方法:本研究共纳入 104 例患者,每例患者在接受至少 21 天的固定剂量拉莫三嗪连续治疗后,测定其血浆中拉莫三嗪的稳态浓度。拉莫三嗪的血浆浓度采用超高效液相色谱法测定。同时,血浆样本还用于患者基因分型:结果:患者的年龄、性别、体重指数、每日拉莫三嗪剂量、血浆拉莫三嗪浓度和拉莫三嗪浓度/剂量比均存在显著差异,这些差异与基因型的不同有关[UGT1A4 -142T>G和UGT2B7 -161C>T(P G的拉莫三嗪浓度/剂量值明显更高(1.6 ± 1.1 和 1.7 ± 0.5 μg/ml per mg/kg)。同样,UGT2B7 -161C>T TT 基因型患者的拉莫三嗪浓度/剂量值(每 mg/kg 1.6 ± 1.1 μg/ml)也明显高于 CC 基因型患者(每 mg/kg 1.3 ± 1.3 μg/ml)。多元线性回归分析表明,性别、拉莫三嗪剂量、UGT1A4 -142T>G和UGT2B7 -161C>T是影响拉莫三嗪药代动力学的最重要因素(P 结论:UGT1A4 -142T>G和UGT2B7 -161C>T是影响拉莫三嗪药代动力学的最重要因素:研究结果表明,UGT1A4 -142T>G和UGT2B7 -161C>T多态性会影响双相情感障碍患者的拉莫三嗪血浆浓度。
