摘要:

摘  要 目的:探讨TCF7L2基因多态性与肾移植后糖尿病(PTDM)的相关性。方法:采用实时荧光定量PCR法检测97例PTDM患者(PTDM组)和301例未发生PTDM的肾移植患者(对照组)的TCF7L2基因 rs290487的基因型,采用 logistic 回归分析该基因多态性与PTDM的相关性。结果:PTDM组和对照组患者rs290487的基因型分布差异具有统计学意义(P<0.05)。用性别、移植时年龄、体重和BMI等危险因素进行校正后,rs290487的CC基因型携带者在肾移植术后发生PTDM的风险是TT基因型携带者的2.300倍(OR=2.300,95% CI :1.196-4.425,P = 0.013);CC+CT基因型携带者在肾移植术后发生PTDM的风险是TT基因型携带者的1.935倍(OR=1.935,95% CI :1.141-3.281,P=0.014)。结论:TCF7L2基因rs290487的多态是中国肾移植受者发生PTDM的独立危险因素。

Abstract:

ABSTRACT  Objective: To investigate the relationship of trascription factor 7 type 2 (TCF7L2) gene polymorphism with the risk of PTDM in Chinese renal allograft recipients. Methodology: A total of three hundred ninety eight unrelated renal allograft recipients without prior diabetes (97 patients with PTDM and 301 patients without PTDM) were genotyped for the presence of TCF7L2 gene rs290487 polymorphism by real-time fluorescence polymerase chain reaction (real-time PCR). Logistic regression method was used to identify risk factors for PTDM development and calculate the odds ratio (OR). Results: The genotype distributions of rs290487 were significantly different between the PTDM patients and controls (P <0.05). The effect of genotype remained significant (CC vs TT, OR=2.300, 95% CI : 1.196-4.425, P = 0.013; CC+CT vs TT, OR=1.935, 95% CI: 1.141-3.281, P =0.014) after adjustments for age, sex, body weight and body mass index (BMI). Conclusions: The C-allele in rs290487 of TCF7L2 is the independent risk factors of PTDM in Chinese renal allograft recipients.
