Albumin has an oxidized form, known as non-mercaptalbumin (HNA), which reflects systemic oxidative stress. The association between serum HNA levels and diabetic complications are yet to be reported. In this cross-sectional study, we investigated 164 diabetic subjects to assess the correlation between HNA% (the proportion in the total albumin) and various clinical parameters. HNA% was significantly associated with the severity of multiple complications including neuropathy (23.3 ± 4.1% vs 26.2 ± 5.1%) and nephropathy (24.1 ± 3.9%, 24.6 ± 4.2%, 28.5 ± 6.1%, 31.3 ± 5.7%, 37.8 ± 2.9%, stage 1/2/3/4/5, respectively). These findings highlight the universal importance of oxidative stress, indicating HNA% potential as a versatile marker of the severity of diabetic complications.
白蛋白有一种氧化形式，称为非巯基白蛋白（HNA），它反映全身氧化应激。血清HNA水平与糖尿病并发症之间的关联尚未见报道。在这项横断面研究中，我们调查了164名糖尿病患者，以评估HNA%（在总白蛋白中的比例）与各种临床参数之间的相关性。HNA%与多种并发症的严重程度显著相关，包括神经病变（分别为23.3±4.1%和26.2±5.1%）和肾病（分别为24.1±3.9%、24.6±4.2%、28.5±6.1%、31.3±5.7%、37.8±2.9%，1/2/3/4/5期）。这些发现突出了氧化应激的普遍重要性，表明HNA%有可能作为糖尿病并发症严重程度的通用标志物。
