Purpose
To investigate the association of hepatic and renal parameters with the development of retinopathy of prematurity (ROP) in premature infants with a gestational age ≤ 32 weeks.
Methods
Medical records of 240 preterm infants were reviewed retrospectively, 85 of them were grouped as type 1, type 2 ROP, and control group. The 4th week hepatic and renal function test results of the groups, on the day of their first ROP examinations, were compared for the risk of development of ROP and the development of type 1 ROP.
Results
In this study, 12, 35, and 38 infants were enrolled in the type 1, type 2 ROP, and control group, respectively. The average gestational age and birth weight were higher; however, the duration of oxygen treatment was lower in the control group (p < 0.001). The blood glucose level was significantly higher in the type 1 ROP group than in the other groups (p = 0.023). The mean of total serum bilirubin of the type 1 ROP group was significantly lower than those of the type 2 ROP and control group (p = 0.032). Proteinuria was present in 85.7% of preterms with treatment-requiring ROP and proteinuria increased the risk of ROP by 3.9 times (OR with 95% CI 3.9 (1.19–12.75), p = 0.042).
Conclusion
We found significantly higher blood glucose and lower total bilirubin level in the type 1 ROP group. Moreover, our findings suggest that proteinuria may not be only a comorbidity factor but also related to a higher frequency of ROP and type 1 ROP in preterm infants.
