Brief Summary

This study explores the relationship between iron deficiency and neurological outcome of extremely premature infants. Premature birth occurs during a critical period of brain development and maturation, and before adequate transfer of iron across the placenta. Nutrition has a significant impact on ultimate outcome of survivors of prematurity. One of the biomarkers of nutrition in the premature infant is iron, and iron supplementation is essential for growth and brain development at low gestational age. As a result, the Committee on Nutrition of the American Academy of Pediatrics (AAP) recommends daily oral iron supplementation, of at least 2-4 mg/kg/day from 2 weeks of age, to prevent iron deficiency in extremely premature infants. Nevertheless, studies have shown that even with this regular care dose of iron, started from 2 weeks of age, a significant number of premature infants will still develop iron-deficiency. Our hypothesis states that starting high dose iron supplementation early will improve neurological development and outcome in extremely premature infants (those born at less than 28 weeks gestational age). This study will provide data showing whether individualized iron supplementation using higher doses of iron, started earlier (after the first week of life) when guided by periodic screening of their body's iron status with ferritin levels, will mitigate iron deficiency and promote improved neurodevelopmental outcome in this vulnerable infant population.

Outcome Measures

Primary Outcomes (1)

  • Neurodevelopmental outcome in participants

    ND impairment (NDI): defined as the presence of any of the following: Bayley Scales of Development III Motor Standard Score, Language or Cognitive Standard Score \< 70 (severe, 2 standard deviations (SD) below mean) or \< 85 (moderate, 1 SD below mean)

    22-26 months corrected age

Secondary Outcomes (4)

  • Iron insufficiency as assessed by ferritin level (ng/mL)

    At discharge or 40 weeks corrected age (whichever occurs first), up to 16 weeks

  • Iron insufficiency as assessed by hemoglobin level (g/dL)

    At discharge or 40 weeks corrected age (whichever occurs first), up to 16 weeks

  • Iron insufficiency as assessed by reticulocyte hemoglobin equivalent (Ret-He, pg)

    At discharge or 40 weeks corrected age (whichever occurs first), up to 16 weeks

  • Iron insufficiency as assessed by reticulocyte count (%)

    At discharge or 40 weeks corrected age (whichever occurs first), up to 16 weeks

Other Outcomes (2)

  • Assess whether measurement of ferritin (ng/mL) or hemoglobin (g/dL) is superior in guiding intervention of iron-insufficiency

    Throughout hospitalization, up to 16 weeks

  • Assess whether measurement of ferritin (ng/mL) or reticulocyte count (%) is superior in guiding intervention of iron-insufficiency

    Throughout hospitalization, up to 16 weeks

Study Arms (2)

Standard iron dose

ACTIVE COMPARATOR

Iron supplementation of 4mg/kg/day will start when infant is on full enteral feedings of 120-150mL/kg/day and at least two weeks old. Iron dosing will be adjusted for weight at weekly intervals to maintain dosing at 4mg/kg/day.

Drug: Iron Sulfate

Early, high-dose iron

EXPERIMENTAL

Iron supplementation will start at 3mg/kg/day when infant is on enteral feeds of 60mL/kg/day and at least one week old, then increased to 6mg/kg/day when enteral feeds are at 100mL/kg/day. Iron dosing will be adjusted to maintain ferritin level of 70-400ng/mL. At 36 weeks corrected age, iron supplementation will be adjusted to the dose routinely used for preterm infants.

Drug: Iron Sulfate
