To investigate whether ischemia-modified albumin (IMA) is reliable for early diagnosing symptomatic lacunar infarction (SLI) in type 2 diabetics.
Ninety-seven consecutive diabetic patients, 47 with SLI, and 45 healthy controls were enrolled. Serum IMA and plasma total homocysteine (tHcy) were measured on an autoanalyzer and evaluated in distinguishing SLI.
Serum IMA levels were 97.35 ± 5.25 U/L in the healthy control group, 103.26 ± 7.43 U/L in the non-SLI group, and 139.84 ± 20.00 U/L in the SLI group. Plasma tHcy levels were 8.08 ± 1.82 μmol/L, 11.31 ± 3.03 μmol/L, and 13.10 ± 3.67 μmol/L, respectively. The differences in IMA and tHcy levels were statistically significant for all groups (p<0.05). Receiver operating characteristic curve analyses revealed the areas under curve were 0.866 for IMA and 0.352 for tHcy.
This study indicates that IMA was significantly elevated in the acute phase of SLI and more sensitive than tHcy in distinguishing SLI.
探讨缺血修饰白蛋白(IMA)是否可用于诊断 2 型糖尿病患者症状性腔隙性梗死(SLI)。
连续纳入 97 例糖尿病患者,其中 47 例为 SLI 患者,45 例为健康对照者。使用自动分析仪检测血清 IMA 和血浆总同型半胱氨酸(tHcy),并评估其在 SLI 中的鉴别诊断价值。
健康对照组血清 IMA 水平为 97.35 ± 5.25 U/L,非 SLI 组为 103.26 ± 7.43 U/L,SLI 组为 139.84 ± 20.00 U/L。血浆 tHcy 水平分别为 8.08 ± 1.82 μmol/L、11.31 ± 3.03 μmol/L 和 13.10 ± 3.67 μmol/L。各组间 IMA 和 tHcy 水平差异均有统计学意义(p<0.05)。受试者工作特征曲线分析显示,IMA 的曲线下面积为 0.866,tHcy 的曲线下面积为 0.352。
本研究表明,IMA 在 SLI 急性期显著升高,且在鉴别 SLI 方面比 tHcy 更敏感。
