There are evidence that oxidative stress and inflammation are involved in the pathogenesis of the age-related macular degeneration (AMD). The aim of this study was to analyze the antioxidant defense parameters and inflammatory markers in patients with exudative form of AMD (eAMD), their mutual correlations and association with the specific forms of AMD. The cross-sectional study, included 75 patients with the eAMD, 31 patients with the early form, and 87 aged-matched control subjects. Significantly lower SOD, TAS and albumin values and higher GR, CRP and IL-6 were found in the eAMD compared to the early form (<0.05). Significant negative correlations were found between GPx and fibrinogen ( = -0.254), TAS and IL-6 ( = -0.999) and positive correlations between uric acid and CRP ( = 0.292), IL-6 and uric acid ( = 0.398) in the eAMD. A significant association of CRP (OR: 1.16, 95% CI: 1.03-1.32, = 0.018), fibrinogen (OR: 2.21, 95% CI: 1.14-4.85, = 0.021), TAS (OR: 7.45, 95% CI: 3.97-14.35, = 0.0001), albumin (OR: 1.25, 95% CI: 1.11-1.41, = 0.0001) and uric acid (OR: 1.006, 95% CI: 1.00-1.02, = 0.003) was found with the eAMD. In conclusion it may be suggested, there is a significant impairment of antioxidant and inflammatory parameter levels in eAMD patients. In addition, significant association exists between the tested inflammatory markers and antioxidant parameters with late-eAMD.
有证据表明氧化应激和炎症参与了年龄相关性黄斑变性(AMD)的发病机制。本研究的目的是分析渗出性AMD(eAMD)患者的抗氧化防御参数和炎症标志物、它们之间的相互关系以及与AMD特定形式的关联。这项横断面研究纳入了75例eAMD患者、31例早期AMD患者和87例年龄匹配的对照受试者。与早期AMD相比,eAMD患者的超氧化物歧化酶(SOD)、总抗氧化能力(TAS)和白蛋白值显著降低,谷胱甘肽还原酶(GR)、C反应蛋白(CRP)和白细胞介素-6(IL-6)升高(<0.05)。在eAMD患者中,谷胱甘肽过氧化物酶(GPx)与纤维蛋白原之间存在显著负相关(r = -0.254),TAS与IL-6之间存在显著负相关(r = -0.999),尿酸与CRP之间存在显著正相关(r = 0.292),IL-6与尿酸之间存在显著正相关(r = 0.398)。CRP(比值比:1.16,95%置信区间:1.03 - 1.32,P = 0.018)、纤维蛋白原(比值比:2.21,95%置信区间:1.14 - 4.85,P = 0.021)、TAS(比值比:7.45,95%置信区间:3.97 - 14.35,P = 0.0001)、白蛋白(比值比:1.25,95%置信区间:1.11 - 1.41,P = 0.0001)和尿酸(比值比:1.006,95%置信区间:1.00 - 1.02,P = 0.003)与eAMD存在显著关联。总之,可以认为,eAMD患者的抗氧化和炎症参数水平存在显著损害。此外,所检测的炎症标志物和抗氧化参数与晚期eAMD之间存在显著关联。
