to explore the aqueous cytokine profiles in nAMD patients before and after conbercept therapy.
aqueous levels of 17 cytokines were detected in 20 treatment-naïve nAMD eyes and 20 age- and sex-matched age-related cataract (ARC) eyes. All of the nAMD patients received three intravitreal injections of conbercept. The central macular thickness (CMT) and maximum retinal thickness-3 mm (MRT-3 mm) were measured by SD-OCT. Fundus fluorescein angiography (FA) was used to measure the greatest linear diameter (GLD).
Aqueous endoglin, endostatin, FGF-α, HGF, and thrombospondin-2 levels were significantly higher in the nAMD group than those in the ARC group, whether before or after two conbercept injections. In the nAMD group, baseline thrombospondin-2 was positively correlated with GLD. Baseline FGF-α, thrombospondin-2, and VEGF-A were positively correlated with MRT-3 mm. After two conbercept injections, endostatin levels were positively correlated with VEGF-A.
Endoglin, endostatin, FGF-α, HGF, and thrombospondin-2 may participate in the pathogenesis of nAMD.
探讨康柏西普治疗 nAMD 患者前后房水中细胞因子的变化。
本研究纳入了 20 例未经治疗的 nAMD 患者和 20 例年龄和性别匹配的年龄相关性白内障（ARC）患者。所有 nAMD 患者均接受了三次康柏西普玻璃体腔内注射。采用 SD-OCT 测量中心黄斑厚度（CMT）和最大视网膜厚度-3mm（MRT-3mm）。荧光素眼底血管造影（FA）用于测量最大线性直径（GLD）。
在接受或不接受两次康柏西普治疗后，nAMD 组房水中的内皮糖蛋白、内皮抑素、FGF-α、HGF 和血栓素-2 水平均显著高于 ARC 组。在 nAMD 组中，基线血栓素-2与 GLD 呈正相关。基线 FGF-α、血栓素-2 和 VEGF-A 与 MRT-3mm 呈正相关。在接受两次康柏西普治疗后，内皮抑素水平与 VEGF-A 呈正相关。
内皮糖蛋白、内皮抑素、FGF-α、HGF 和血栓素-2 可能参与了 nAMD 的发病机制。
