Abstract

OBJECTIVE:

To explore whether early or late and presumed or definite neonatal bacteremia are associated with an increased risk of severe retinopathy of prematurity (ROP).

METHODS:

We evaluated 1059 infants born before week 28 of gestation for ROP. Infants were classified as having early (postnatal week 1) or late (weeks 2-4) definite (culture-proven) or presumed (antibiotics taken for >72 hours despite negative blood culture results) bacteremia. Severe ROP was defined as stage 3 to 5, zone 1, prethreshold/threshold, or plus disease. We used time-oriented risk models to adjust for confounders.

RESULTS:

In univariable, but not multivariable, analysis, newborns with presumed early bacteremia were at increased risk for plus disease (odds ratio [OR], 1.7; 95% CI, 1.1-2.7), and those with definite early bacteremia were at increased risk for stage 3 to 5 disease (1.9; 1.1-3.2). Infants who had presumed or definite late bacteremia were at increased risk for all 4 indicators of severe ROP in univariable analysis. In multivariable analysis, newborns with presumed late bacteremia were at increased risk for prethreshold/threshold ROP (OR, 1.8; 95% CI, 1.02-3.2), and those with definite late bacteremia were at increased risk for prethreshold/threshold ROP (1.8; 1.1-2.9) and plus disease (1.8; 1.05-2.9).

CONCLUSIONS:

Definite late neonatal bacteremia seems to be an independent risk factor for prethreshold/threshold ROP and plus disease, and presumed late bacteremia seems to be related to prethreshold/threshold ROP.
