To evaluate pentraxin3 (PTX3) levels in patients with neovascular age-related macular degeneration (N-ARMD) and to investigate its role as a predictive biomarker.
Thirty individuals with N-ARMD and 30 controls without N-ARMD were studied. Plasma concentrations of C-reactive protein (CRP) and PTX3 were measured in frozen samples using an enzyme-linked immunosorbent assay kit.
PTX3 concentration was 1341 ± 625 pg/mL (mean ± standard deviation) in N-ARMD patients, which was significantly higher than in control subjects (887 ± 478, p = 0.003). The mean CRP level was also significantly higher in N-ARMD (2121 ± 2300) than in control (748 ± 618, p = 0.004). Pearson's correlation analysis showed a significant positive correlation between PTX3 and CRP (r = 0.407, p = 0.002).
Our data support the role of chronic inflammation in the development of ARMD. They also show PTX3 may contribute to efforts to understand pathogenesis of N-ARMD.
评估新生血管性年龄相关性黄斑变性(N-ARMD)患者血清中五聚体蛋白3(PTX3)水平,并探讨其作为预测生物标志物的作用。
研究纳入30例N-ARMD患者和30例非N-ARMD对照者。采用酶联免疫吸附测定试剂盒检测冻存样本中C反应蛋白(CRP)和PTX3的血浆浓度。
N-ARMD患者PTX3浓度为1341±625 pg/mL(平均值±标准差),显著高于对照组(887±478,p = 0.003)。N-ARMD患者的平均CRP水平(2121±2300)也显著高于对照组(748±618,p = 0.004)。Pearson相关性分析显示PTX3与CRP之间存在显著正相关(r = 0.407,p = 0.002)。
我们的数据支持慢性炎症在年龄相关性黄斑变性发病中的作用。这些数据还表明PTX3可能有助于理解N-ARMD的发病机制。
