ABSTRACT

This study was designed to investigate the relationship between variants of matrix metalloproteinases (MMP-1 rs179975, MMP-9 rs17576 and rs17577), their tissue inhibitors (TIMP-1 rs4898, TIMP-2 rs2277698 and rs55743137) and the development of retinopathy of prematurity (ROP) in infants from the Polish population. A cohort of 100 premature infants (47% female) was enrolled, including 50 ROP cases and 50 no-ROP controls. Patients with ROP were divided into those with spontaneous remission and those requiring treatment. A positive association between MMP-1 rs179975 1G deletion allele and ROP was observed in the log-additive model (OR = 5.01; p = 0.048). Furthermore, female neonates were observed to have a negative association between the TIMP-1 rs4898C allele and the occurrence of ROP and ROP requiring treatment (codominant models with respective p-values < 0.05 and 0.043). Two and three loci interactions between MMP-1 rs1799750 and TIMP1rs4989 (p = 0.015), as well as MMP-1 rs1799750, MMP-9 rs17576 and TIMP-1 rs4989 (p = 0.0003) variants influencing the ROP risk were also observed. In conclusion, these findings suggest a potential role of MMPs and TIMPs genetic variations in the development of ROP in the Polish population. Further studies using a larger group of premature infants will be required for validation.

ABSTRACT

The aim of this study was to investigate the association between selected polymorphisms of nitric oxide synthetase (eNOS) and endothelin-1 (EDN-1) with the occurrence and progression of retinopathy of prematurity (ROP). A prospective study was conducted on 90 preterm infants (44 female), comparing 39 cases with ROP and 51 controls without ROP. Patients who developed ROP were further divided into two subgroups-those with spontaneous regression of the disease and those with ROP requiring treatment. We found that preterm infants with TT genotype eNOS 894G > T had a 12.8-fold higher risk of developing ROP requiring treatment (p = 0.02). Our results showed that allele T of eNOS894G > T polymorphism was significantly more prevalent in ROP patients requiring treatment (p = 0.029). We also investigated preterm infants with TC genotype eNOS - 786 T > C and found an 8.8-fold higher risk developing of ROP requiring treatment (p = 0.021). Our results didn't show any association between EDN-1 5665G > T polymorphism and ROP development. The eNOS polymorphisms appears to influence incidence of ROP requiring treatment in preterm infants. Future research on single nucleotide polymorphisms may provide important information about the pathogenetic mechanisms underlying the development of ROP.
