摘要
目的探讨2型糖尿病患者血清γ-谷氨酰转肽酶(GGT)水平与糖尿病周围神经病变(DPP)的关系。方法随机选择2010年1月至2011年12月于南京军区总医院内分泌科就诊的159例2型糖尿病患者,检测身高、体重、空腹血糖(FBG)、糖化血红蛋白(HbAlc)、谷丙转氨酶(ALT)、谷草转氨酶(AST)、GGT、尿素氮(BUN)、肌酐(Cr)、血脂水平等数据。根据密西根评分系统及神经传导速度将患者分为有周围神经病变组(DPP组)和无周围神经病变组(无DPP组),其中DDP组患者82例,平均年龄(57±13)岁,无DPP组患者77例,平均年龄(56±12)岁。同时将患者按GGT水平分为:A组(GGT≤50U/L)、B组(GGT〉50U/L),其中A组115例,平均年龄(56±14)岁,B组44例,平均年龄(58±13)岁。样本均数比较采用t检验,采用多因素logistic回归分析DPP的危险因素。结果与无DPP组相比,DPP组患者体重[(69±13)比(66±9)kg,t=1.854,P〈0.05]、血清GGT[(32±25)比(18±9)U/L,t=4.310,P〈0.01]、ALT[(24±17)比(19±7)U/L,t=2.304,P〈0.05]、甘油三酯[(2.5±2.0)比(1.4±0.9)mmol/L,t=4.165,P〈0.01]、HbAlc[(9.4±3.0)%比(8.6±1.9)%,t=-1.727,P〈0.05]显著增高。A组患者ALT、AST显著低于B组[(16±11)比(34±17)U/L和(17±7)比(29±15)U/L;t=3.721、2.669,P〈0.05],同时A组患者的胫神经运动传导速度(MCV)、腓总神经运动传导速度(MCV)及腓总神经感觉传导速度(SCV)均优于B组[(45.4±5.0)比(40.3±5.6)m/s、(47.3±4.8)比(40.2±5.4)m/s和(48.4±5.1)比(41.3±9.7)m/s,t=4.031、4.110、4.006,P〈0.05]。对在DPP组和无DPP组间差异有统计学意义的5个指标与DPP再进行多因素logistic回归分析发现,只有血清GGT与DPP的发生显著相关(优势比为1.10,P〈0.05)。结论血清高GGT水平与2型糖尿病患者周围神经病变的发生存在一定相关性,是周围神经病变的可能危险因素。
Objective To evaluate the association between serum γ-glutamyl transferase(GGT) and diabetic peripheral polyneuropathy(DPP) in type 2 diabetics. Methods From January, 2010 to December, 2011, 159 cases of type 2 diabetics were enrolled randomly from the endocrine department of our hospital. Height, weight, fasting blood glucose (FBG), glycosylated hemoglobin( HbA1 c), alanine aminotransferase, aspartate aminotransferase, creatinine, blood urea nitrogen, blood fat were detected in all patients. Patients were divided into two groups( DPP, non-DPP) accordinging to Michigan Neuropathy Screening Instrument (MNSI) and nerve conduction velocity(NCV) examinations. There were 82 patients in the DPP group with a mean age of (57 ± 13 ) yrs ,77 patients in the non-DPP group with a mean age of (56 ± 12) yrs. All patients were also divided into two groups according to serum GGT level: group A ( GGT≤ 50 U/L) and group B ( GGT 〉 50U/L) , and there were 115 patients in group A ( mean age ( 56 ± 14) yrs) ,44 patients in group B (mean age (58 ± 13) yrs). T test was implied in the comparison of data between the two groups, and the risk factors of DPP were investigated with multiple logistic regression. Results The body weight ( (69 ± 13 )vs (66 ±9)kg, t =1.854, P〈0.05), serum GGT ((32±25) vs (18 ±9)U/L, t =4.310, P〈0.01), alanine aminotransferase ( (24 ± 17) vs (18 ±7)U/L, t =2. 304, P〈0. 05), triglyceride ( (2.5 ±2. 0) vs ( 1.4 ± 0. 9) mmol/L, t = 4. 165, P 〈 0. 01 ), glycosylated hemoglobin ( HbA1 c) ( (9.4 ± 3.0) % vs ( 8.6 ± 1.9) %, t = - 1. 727, P 〈 0.05) were higher in DPP group than those in non-DPP group. Serum alanine aminotransferase ,aspartate aminotransferase in patients of group A were significantly lower than those in patients of group B ( (16 ± 11 ) vs (34 ± 17)U/L and ( 17 ± 7 ) vs (29 ± 15 )U/L, t = 3.721, 2. 669, both P 〈 0. 05 ). The tibial nerve motor conduction velocity, common peroneal nerve and peroneal nerve sensory conduction velocity in group A were better than those in group B ( ( 45.4 ± 5.0 ) vs ( 40. 3 ± 5.6 ) m/s, (47.3±4.8) vs (40.2±5.4) m/s, and (48.4±5.1) vs (41.3 ±9.7)m/s, respectively; t =4.031, 4. 110, 4. 006, all P 〈 0. 05 ). Multiple logistic regression analysis implied that of the five significant variables between DPP group and non-DPP group, only serum GGT remained independently associated with the presence of DPP, which carried a relative risk with an odds ratio of 1.10 ( P 〈 0. 05 ). Conclusion It shows that increased level of serum GGT have important clinical implications in the presence of DPP, may be a risk factor of DPP in type 2 diabetes mellitus.
