Symptomatic zinc deficiency in breast-fed premature infants.
We report two breast-fed premature infants who developed transient symptomatic zinc deficiency with scaly erythema of cheeks and napkin area, 9-13 weeks after birth. Serum zinc concentrations were 3.6 and 4.8 mumols/l, and the lesions healed rapidly in response to oral zinc supplements. Both mothers had low breast-milk zinc levels (2.3 and 3.2 mumols/l at 21 and 15 weeks respectively). The infants were both initially misdiagnosed as having eczema and infection. Premature infants are in negative zinc balance and though the additional factor of a low maternal breast milk zinc concentration may be necessary to provoke symptoms, rashes developing in such infants in the months following premature birth should raise the suspicion of zinc deficiency.
