PURPOSE
To determine the role tear lymphotoxin-α (LT-α) in chronic ocular graft-versus-host disease (oGVHD).
METHODS
Twenty-two chronic oGVHD and 17 control tear samples were collected, and commercial test strips were used to detect LT-α concentrations. Concentration differences between patients with and without oGVHD were determined via Mann-Whitney U test. The correlation between LT-α levels and ophthalmic parameters was analyzed using Spearman's test.
RESULTS
The concentration of LT-α was significantly lower in oGVHD patients than in controls. LT-α levels were significantly correlated with OSDI, NIH eye score, T-BUT, and CFS among all participants. ROC analysis revealed that the area under the curve of LT-α was 0.847, and the cutoff value for chronic oGVHD diagnosis was 0.203 ng/mL.
CONCLUSION
Our study revealed the significant decrease of tear LT-α in oGVHD, and suggested LT-α as a promising marker for chronic oGVHD diagnosis.
目的
确定泪液淋巴毒素-α（LT-α）在慢性眼移植物抗宿主病（oGVHD）中的作用。
方法
收集 22 例慢性 oGVHD 和 17 例对照的泪液样本，并使用商业检测条检测 LT-α浓度。通过 Mann-Whitney U 检验确定 oGVHD 患者和无 oGVHD 患者之间的浓度差异。使用 Spearman 检验分析 LT-α 水平与眼科参数之间的相关性。
结果
oGVHD 患者的 LT-α 浓度明显低于对照组。在所有参与者中，LT-α 水平与 OSDI、NIH 眼评分、T-BUT 和 CFS 均呈显著相关。ROC 分析显示，LT-α 的曲线下面积为 0.847，慢性 oGVHD 诊断的截断值为 0.203ng/mL。
结论
本研究揭示了 oGVHD 患者泪液 LT-α 的显著降低，并提示 LT-α 可能成为诊断慢性 oGVHD 的有前途的标志物。
