BACKGROUND/AIM: Results show that oxidative stress is a pathophysiologic factor for alopecia areata (AA); however, the markers used can be confounding. Thus, we aimed to investigate the role of oxidative stress in the pathogenesis of AA through an evaluation of ischemia-modified albumin (IMA); other markers of the oxidant/antioxidant system, such as SOD, CAT, GSH-ST, and MDA; and contributing clinical risk factors.
The usefulness of IMA as a new marker for oxidative stress was compared with that of other markers and evaluated in patients with AA.
The mean serum level of IMA was of higher statistical significance in AA patients than in the control group (IMA: 0.57 ± 0.01 vs. 0.52 ± 0.02 ΔABSU, P < 0.0001). IMA (P = 0.03, OR = 25.8, 95% CI = 1.4–482.7) was found to be an independent predictor of oxidative stress in patients with AA. Increased severity of AA was found as an independent risk factor for IMA.
Long-lasting disease, male sex, >1 site of involvement of disease, and increased severity of disease were correlated with increased oxidation. Presence of AA, male sex, and severe disease were determined to be independent risk factors for antioxidant and oxidant systems. IMA has great potential as a biomarker of oxidative stress in AA when compared to other studied biomarkers.
背景/目的:研究结果表明氧化应激是斑秃(AA)的病理生理因素;然而,所用的标志物可能存在混杂因素。因此,我们旨在通过评估缺血修饰白蛋白(IMA);其他氧化应激标志物,如 SOD、CAT、GSH-ST 和 MDA;以及相关的临床危险因素,来研究氧化应激在 AA 发病机制中的作用。
将 IMA 作为氧化应激的新标志物的有用性与其他标志物进行比较,并在 AA 患者中进行评估。
AA 患者的平均血清 IMA 水平明显高于对照组(IMA:0.57±0.01 对 0.52±0.02ΔABSU,P<0.0001)。IMA(P=0.03,OR=25.8,95%CI=1.4–482.7)被发现是 AA 患者氧化应激的独立预测因子。AA 的严重程度增加被认为是 IMA 的独立危险因素。
疾病持续时间长、男性、疾病累及部位>1 个和疾病严重程度增加与氧化增加相关。AA 的存在、男性和严重疾病被确定为抗氧化和氧化系统的独立危险因素。与其他研究的生物标志物相比,IMA 作为 AA 氧化应激的生物标志物具有很大的潜力。
