The controversial data related to oxidative stress status in patients with chronic idiopathic urticaria (CIU) have been reported. Therefore, the present study was aimed to contribute to this debate by determining oxidative stress markers along with some trace element levels in patients with CIU.
Twenty-five patients with CIU (10 males, 15 females) and 36 healthy controls were enrolled into the study. Erythrocyte lipid peroxidation status, scavenger enzyme activities and trace element levels were determined.
While erythrocyte MDA levels, erythrocyte GSH- Px activities and erythrocyte Zn levels showed no differences between the patient and control groups, a statistically significant decrease and increase were observed in erythrocyte CuZn-SOD activities and Cu levels, respectively, in the CIU patients when compared to those of the controls (p < 0.001 for both of them).
In conclusion, an oxidative burden which can be relieved by some preserved antioxidant mechanisms seems to be present in patients with CIU even if they are clinically stable and it may probably have a role in the pathogenesis.
已有关于慢性特发性荨麻疹(CIU)患者氧化应激状态的争议性数据报道。因此,本研究旨在通过测定CIU患者的氧化应激标志物以及一些微量元素水平,为这一争论提供参考。
本研究纳入了25例CIU患者(10例男性,15例女性)和36例健康对照者。测定了红细胞脂质过氧化状态、清除酶活性和微量元素水平。
患者组和对照组的红细胞丙二醛(MDA)水平、红细胞谷胱甘肽过氧化物酶(GSH-Px)活性和红细胞锌水平无差异,但与对照组相比,CIU患者的红细胞铜锌超氧化物歧化酶(CuZn-SOD)活性和铜水平分别出现了统计学上的显著降低和升高(两者p均<0.001)。
总之,即使CIU患者临床症状稳定,其体内似乎仍存在可通过某些保留的抗氧化机制缓解的氧化负担,这可能在其发病机制中起作用。
