: The age-related macular degeneration (AMD) pathophysiology is multifactorial, as it consists of interactions between aging, genetic, and environmental factors. We aimed to determine a relationship between AMD and the genes controlling lipid metabolism, and to assess its association with treatment results. The purpose was to find the rs1883025 and rs2108622 gene polymorphisms in patients with exudative AMD (eAMD) treated with anti-VEGF. : The study enroled 104 patients with eAMD and 201 healthy persons in a control group. The genotyping of rs1883025 and rs2108622 was performed using the RT-PCR method. The best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were measured before anti-VEGF therapy, then at three and six months during the therapy, using optical coherence tomography (OCT). The patients were grouped to responders and non-responders according to the changes in BCVA and CRT. : The T allele at rs1883025 was more frequent in non-responder eAMD patients compared to responder eAMD patients (41.7% vs. 21.1%; = 0.009). The analysis of rs2108622 gene polymorphism did not reveal any differences in the distribution of C/C, C/T, and T/T genotypes between the eAMD group and the control group (56.35%, 39.78%, and 3.87% in the eAMD group and 53.33%, 39.05% and 7.62% in the control group, respectively, = 0.286). The comparison of CRT and BCVA between the rs2108622 genotypes revealed statistically significant differences: CRT was thicker for the CC carriers than for those with CT and TT genotypes ( = 0.030). : The rs1883025 T allele was found to play a more significant role in non-responder eAMD patients compared to responder eAMD patients. The rs2108622 genotypes revealed statistically significant differences: CRT was thicker for the CC carriers than for those with CT and TT genotypes.
: 年龄相关性黄斑变性 (AMD) 的发病机制是多因素的,因为它包括衰老、遗传和环境因素之间的相互作用。我们旨在确定 AMD 与控制脂质代谢的基因之间的关系,并评估其与治疗结果的关联。目的是在接受抗血管内皮生长因子 (VEGF) 治疗的渗出性 AMD (eAMD) 患者中发现 rs1883025 和 rs2108622 基因多态性。 : 该研究纳入了 104 例 eAMD 患者和 201 名健康对照者。使用 RT-PCR 方法对 rs1883025 和 rs2108622 进行基因分型。在接受抗 VEGF 治疗前、治疗后 3 个月和 6 个月,使用光学相干断层扫描 (OCT) 测量最佳矫正视力 (BCVA) 和中心视网膜厚度 (CRT)。根据 BCVA 和 CRT 的变化,将患者分为应答者和无应答者。 : rs1883025 的 T 等位基因在无应答 eAMD 患者中比在应答 eAMD 患者中更为常见(41.7%比 21.1%; = 0.009)。rs2108622 基因多态性分析未显示 eAMD 组与对照组之间 C/C、C/T 和 T/T 基因型的分布有任何差异(eAMD 组分别为 56.35%、39.78%和 3.87%,对照组分别为 53.33%、39.05%和 7.62%, = 0.286)。rs2108622 基因型的 CRT 和 BCVA 比较显示有统计学差异:CC 携带者的 CRT 比 CT 和 TT 基因型携带者更厚( = 0.030)。 : rs1883025 T 等位基因在无应答 eAMD 患者中比在应答 eAMD 患者中发挥更重要的作用。rs2108622 基因型显示有统计学差异:CC 携带者的 CRT 比 CT 和 TT 基因型携带者更厚。
