Abstract
The present study investigates the relationship between diabetes metabolic control represented by levels of HbA1c, early glycation products-(fructosamine (FAM)), serum-advanced glycation end products (s-AGEs), lipoperoxidation products (LPO), advanced oxidation protein products (AOPP) and circulating TGF-β in young patients with DM1. The study group consisted of 79 patients with DM1 (8-18 years). 31 healthy children were used as control (1-16 years). Baseline characteristics of patients were compared by Student's t-test and nonparametric Mann-Whitney test (Statdirect), respectively. The correlations between the measured parameters were examined using Pearson correlation coefficient r and Spearman's rank test, respectively. A P value < 0.05 was considered as statistically significant. HbA1c was measured by LPLC, s-AGEs spectrofluorimetrically, LPO and AOPP spectrophotometrically and TGF-β by ELISA. Our results showed that parameters of glycation and oxidation are significantly higher in patients with DM1 than in healthy control. The level of serum TGF-β was significantly higher in diabetics in comparison with control: 7.1(3.6; 12.6) versus 1.6(0.8; 3.9) ng/mL. TGF-β significantly correlated with age and duration of DM1. There was not found any significant relation between TGF-β and parameres of glycation and oxidation. However, these results do not exclude the association between TGF-β and the onset of diabetic complications.
本研究探讨了以HbA1c、早期糖基化产物-(果糖胺(FAM))、血清晚期糖基化终产物(s-AGEs)、脂质过氧化产物(LPO)、晚期氧化蛋白产物(AOPP)水平为代表的糖尿病代谢控制与年轻DM1患者循环TGF-β之间的关系。研究组包括79例DM1患者(8-18岁)。31名健康儿童(1 ~ 16岁)作为对照。分别采用学生t检验和非参数Mann-Whitney检验(Statdirect)比较患者的基线特征。测量参数之间的相关性分别采用Pearson相关系数r和Spearman秩检验。P值< 0.05为有统计学意义。采用LPLC、s-AGEs分光光度法测定糖化血红蛋白,采用LPO、AOPP分光光度法测定糖化血红蛋白,ELISA法测定TGF-β。我们的研究结果表明,DM1患者的糖基化和氧化参数明显高于健康对照。糖尿病患者血清TGF-β水平显著高于对照组:7.1(3.6;12.6) vs . 1.6(0.8;3.9 ng / mL。TGF-β与DM1年龄、病程显著相关。TGF-β与糖基化和氧化参数之间无显著相关性。然而,这些结果并不能排除TGF-β与糖尿病并发症发生之间的关联。
