The aim of this study was to determine the diagnostic and prognostic significance of ischemia modified albumin (IMA) levels in patients with Crimean-Congo hemorrhagic fever (CCHF). This retrospective study was conducted with patients with CCHF. IMA levels in patients with CCHF were determined using the rapid colorimetric method. IMA levels of CCHF patients were significantly higher compared with the control group (P = 0.0001). At an IMA cut-off point of 0.555 ABSU (absorbance units), sensitivity was 65.1%, specificity 82.5%, positive predictive values (PPV) 82.5%, and negative predictive values (NPV) 65.1%. IMA levels of patients with hemorrhage were significantly higher compared with patients without hemorrhage (P = 0.005). IMA has been validated as both a new and sensitive ischemia and oxidative stress biomarker. In addition to its diagnostic significance, IMA investigated in CCHF patients at time of arrival may be an important marker with its prognostic role in determining in the early stage whether the disease will follow a hemorrhagic course.
本研究旨在探讨缺血修饰白蛋白(IMA)水平在克里米亚-刚果出血热(CCHF)患者中的诊断和预后意义。这是一项回顾性研究,纳入了 CCHF 患者。采用快速比色法测定 CCHF 患者的 IMA 水平。CCHF 患者的 IMA 水平明显高于对照组(P=0.0001)。IMA 截断值为 0.555 ABSU(吸光度单位)时,灵敏度为 65.1%,特异性为 82.5%,阳性预测值(PPV)为 82.5%,阴性预测值(NPV)为 65.1%。有出血的患者的 IMA 水平明显高于无出血的患者(P=0.005)。IMA 已被验证为一种新的、敏感的缺血和氧化应激生物标志物。除了其诊断意义外,在 CCHF 患者到达时检测 IMA 可能是一个重要的标志物,其预后作用在于早期确定疾病是否会出现出血过程。
