Iron deficiency and anemia remain significant health problems worldwide. These may he associated with developmental delay and poor mental development. A source of exogenous iron, is therefore, advisable after four to five months of age for breast-fed babies. Artificially-fed infants should be given iron-fortified formula from birth.
Peters C - - 1996
Erythropoietin, the primary stimulator of erythropoiesis, represents an important potential therapy for the anemia of prematurity. Enhancement of the therapeutic benefit of recombinant human erythropoietin (rhEp) in very-low-birth-weight infants will require a better understanding of rhEp's pharmacodynamic effects including its interaction with iron in stimulating erythropoiesis. The purpose of this ...

Neonatal liver (storage) but not heart (nonstorage) tissue iron concentrations were reduced by 60% at autopsy in 15 newborn infants who had gestations complicated by uteroplacental insufficiency because of maternal hypertension or Potter syndrome. The hepatic iron reductions in term and preterm infants, and with either antecedent condition, were similar.
Zlotkin S H - - 1995
Due to limited erythropoiesis, iron needs for the premature infant during the first 2 months of life are low. With the potential for increased use of erythropoietin in the preterm infant, iron requirements may become markedly higher. The ability of the preterm infant to absorb iron, therefore, becomes crucial. Previous ...

Animal experimentation has shown that early iron deficiency irreversibly affects brain iron content and distribution, resulting in neutransmitter and behavioural alterations. Even though extrapolation of animal data is often misleading, iron-deficiency anaemia has been consistently shown to be associated with psychomotor delays in infancy. The areas most involved are language ...
Abrams S A - - 1994
The optimal evaluation of iron metabolism requires the administration of two isotopes of iron. However, high-precision measurement of isotopic ratios from blood samples obtained after administration of two stable isotopes of iron to human subjects has not previously been reported. Using a cation-exchange system to isolate iron from blood samples, ...
