20.500.12556/RUL-186771 Inflammation and oxidative stress gene variability in retinal detachment patients with and without proliferative vitreoretinopathy This study investigated the association between certain genetic variations and the risk of developing proliferative vitreoretinopathy (PVR) after surgery. The study was conducted on 192 patients with primary rhegmatogenous retinal detachment (RRD) who underwent 3-port pars plana vitrectomy (PPV). The distribution of single nucleotide polymorphisms (SNPs) located in genes involved in inflammation and oxidative stress associated with PVR pathways were analyzed among patients with and without postoperative PVR grade C1 or higher. A total of 7 defined SNPs of 5 genes were selected for genotyping: rs4880 (SOD2); rs1001179 (CAT); rs1050450 (GPX1); rs1143623, rs16944, rs1071676 (IL1B); rs2910164 (MIR146A) using competitive allele-specific polymerase chain reaction. The association of SNPs with PVR risk was evaluated using logistic regression. Furthermore, the possible association of SNPs with postoperative clinical parameters was evaluated using nonparametric tests. The difference between two genotype frequencies between patients with or without PVR grade C1 or higher was found to be statistically significant: SOD2 rs4880 and IL1B rs1071676. Carriers of at least one polymorphic IL1B rs1071676 GG allele appeared to have better postoperative best-corrected visual acuity only in patients without PVR (p = 0.070). Our study suggests that certain genetic variations may play a role in the development of PVR after surgery. These findings may have important implications for identifying patients at higher risk for PVR and developing new treatments. rhegmatogenous retinal detachment proliferative vitreoretinopathy single nucleotide polymorphism true false true Angleški jezik Ni določen Članek v reviji 2026-09-05 08:19:11 2026-09-10 07:55:54 2026-09-11 04:28:06 0000-00-00 00:00:00 2023 0 0 12 str. iss. 4 Vol. 14 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 61 2073-4425 10.3390/genes14040804 175039235 RAZ_Lumi_Xhevat_2023.pdf RAZ_Lumi_Xhevat_2023.pdf 1 AC184F23E22653EA51C253C720AA1617 c8a5cc663a8fa40827ec044e95ae05e2bfc7f0b99e2eb0571e15e62c2a0fb156 e7c7ef45-acdc-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246851 https://www.mdpi.com/2073-4425/14/4/804 1 b51ea4d4-a8f1-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246142 Medicinska fakulteta 0 0 0
