PURPOSE: To examine the relationship between the intake of sugar inositol, serum inositol levels, and ROP in three groups of low birthweight infants receiving feedings containing various concentrations of inositol.
METHODS: Infants with a birthweight <1500 g, with severe lung disease, were eligible for the study when they began enteral feedings. Infant formulas contained three different inositol concentrations: 2500, 710, and 242 micromol/L. Serum inositol concentrations were averaged over specific time intervals. A logistic regression model was used to investigate the confounding effect of duration of mechanical ventilation and oxygen therapy, birthweight, Apgar score, and serum inositol concentration on development of ROP.
RESULTS: Infants receiving high inositol formula and with higher serum inositol concentrations at birth and after 30 days had a statistically significant lower incidence of severe ROP than those receiving the lower inositol formula and with lower serum concentrations (P<.05). The effective serum inositol concentration (EC90) associated with lesser disease was >215 micromol/L. By logistic regression, the odds of developing severe ROP were greater among infants with low serum inositol concentration (odds ratio=4.7, 95% confidence interval 0.90-24.8, P=.017).
CONCLUSION: Inositol supplementation may help prevent the most severe form of ROP.
