INTRODUCTION: A growing body of evidence shows that genetics plays a vital role in the development and progression of retinopathy of prematurity (ROP). Perinatal inflammation is also considered an important risk factor of ROP. Therefore, understanding the interplay of genetics and susceptibility to inflammation might shed light on the pathogenesis of ROP and make its screening and treatment more effective in preventing visual impairment in premature infants.
MATERIAL AND METHODS: This study investigated the correlation of inflammation-associated gene polymorphisms: IL-1β +3953 C>T, IL-1RN VNTR 86 bp, IL-6 -174 G>C, IL-6 -596 G>A, and TNF-α -308 G>A as well as demographic and clinical characteristics of ROP in preterm infants (n = 90).
RESULTS: Our results demonstrate that IL-1RN rs2234663 1/1 genotype prevails in infants with ROP that regresses without intervention, when compared to those requiring laser photocoagulation/anti-VEGF injection (p = 0.031). Genotype 2/2 of IL-1RN occurs more frequently in children with severe ROP (28.6%) than in the group in which ROP regressed spontaneously (4.0%). The analysis revealed also differences between the genotypes of IL-1RN in ROP patients with intrauterine infection and in patients who had ROP without intrauterine infection; however, this was not statistically significant. Other studied polymorphisms were not associated with ROP development or its progression.
CONCLUSIONS: These results suggest that different genotypes of IL-1RN might have an impact on the course of ROP. Genotype 2/2 of IL-1RN gene may predispose to ROP progression.
