The study aimed to evaluate the pre-treatment and post-treatment oxidant capacity, antioxidant capacity and S100B protein levels in cases of diabetic ketoacidosis (DKA).
The study included 49 pediatric patients diagnosed with DKA and a control group comprising 49 healthy children. Blood samples were obtained after confirmation of the DKA diagnosis and also after treatment. S100B, total oxidant (TOL) and total antioxidant levels (TAL) were measured and the oxidative stress index (OSI) was calculated.
When the pre-treatment and post-treatment values of patients with DKA were compared with those of the healthy control group, the S100B level, TOL, TAL and OSI were found to be significantly higher in the diabetes group (p<0.001). Pre-treatment TOL and TAL were also significantly higher than post-treatment levels (p<0.001), while no statistically significant difference was found in the S100B levels or the OSI (p>0.05).
We believe that long-term exposure to high blood glucose concentrations leads to an increase in TOL in patients with DKA and that the neurotransmitter changes that develop in response to this exposure lead to an increase in S100B levels, which is an indicator of neuronal damage.
本研究旨在评估糖尿病酮症酸中毒(DKA)患者治疗前和治疗后的氧化能力、抗氧化能力及S100B蛋白水平。
本研究纳入了49例诊断为DKA的儿科患者以及由49名健康儿童组成的对照组。在确诊DKA后及治疗后采集血样。检测S100B、总氧化剂(TOL)和总抗氧化水平(TAL),并计算氧化应激指数(OSI)。
将DKA患者治疗前和治疗后的数值与健康对照组进行比较时,发现糖尿病组的S100B水平、TOL、TAL和OSI显著更高(p<0.001)。治疗前的TOL和TAL也显著高于治疗后水平(p<0.001),而S100B水平或OSI未发现统计学上的显著差异(p>0.05)。
我们认为,长期暴露于高血糖浓度会导致DKA患者的TOL升高,并且由此暴露引发的神经递质变化会导致S100B水平升高,S100B是神经元损伤的一个指标。
