在这项研究中,我们比较了增殖性糖尿病视网膜病变(PDR)患者与非PDR患者的玻璃体细胞因子谱。PDR发病机制中涉及的新型细胞因子的鉴定提供了候选治疗靶点,这些靶点可以单独存在或与糖尿病视网膜病变管理中的当前疗法协同作用。收集了74例因各种玻璃体视网膜疾病接受玻璃体切除术的患者的未稀释玻璃体液标本。对每个标本中的一组36种神经炎性细胞因子进行定量免疫测定,并进行评估以确定PDR(n = 35)和非PDR(n = 39)患者之间的差异。与非PDR患者相比,PDR患者玻璃体中的白细胞介素-8(IL-8)、IL-15、IL-16、血管内皮生长因子(VEGF)、VEGF-D、C-反应蛋白(CRP)、血清淀粉样蛋白-A(SAA)和细胞内粘附分子-1(ICAM 1)的水平显著升高(p < 0.05)。我们报告了PDR患者玻璃体液中IL-15和IL-16的新增加,以及预期的VEGF。此外,我们证实了先前已描述的PDR患者玻璃体中ICAM-1、VCAM-1、SAA、IL-8和CRP的升高。
In this study, we compare the vitreous cytokine profile in patients with proliferative diabetic retinopathy (PDR) to that of patients without PDR. The identification of novel cytokines involved in the pathogenesis of PDR provides candidate therapeutic targets that may stand alone or work synergistically with current therapies in the management of diabetic retinopathy. Undiluted vitreous humor specimens were collected from 74 patients undergoing vitrectomy for various vitreoretinal disorders. Quantitative immunoassay was performed for a panel of 36 neuroinflammatory cytokines in each specimen and assessed to identify differences between PDR (n = 35) and non-PDR (n = 39) patients. Levels of interleukin-8 (IL-8), IL-15, IL-16, vascular endothelial growth factor (VEGF), VEGF-D, c-reactive protein (CRP), serum amyloid-A (SAA), and intracellular adhesion molecule-1 (ICAM1) were significantly increased in the vitreous of PDR patients compared to non-PDR patients (p < 0.05). We report novel increases in IL-15 and IL-16, in addition to the expected VEGF, in the human vitreous humor of patients with PDR. Additionally, we confirm the elevation of ICAM-1, VCAM-1, SAA, IL-8 and CRP in the vitreous of patients with PDR, which has previously been described.
