Re: Ever heard of a baby being allergic to BM?

from a google search for pku and breastmilk. possible but rare. hth!


The initials "PKU" stand for phenylketonuria. This is an extremely rare genetic disorder where a person has a deficiency in the liver enzyme phenylalanine hydroxylase. This enzyme is necessary to metabolize the amino acid phenylalanine which is found in most foods. If a baby cannot metabolize the large amounts of phenylalanine found in breast milk and most formulas, metabolites will accumulate in the blood. If this disorder remains undetected and untreated, infants may experience tremors, seizures, eczema, hypopigmentation, hyperactivity and a failure to grow and develop at a normal rate. By six months of age, the untreated infant with PKU may begin to show signs of mental retardation and could eventually have an IQ of less than 50.

When an infant is tested soon after birth and is found to have PKU, proper treatment can prevent the development of these serious complications. The treatment involves a very restrictive diet low in phenylalanine. This diet should be implemented as soon as the PKU disorder is detected to achieve the optimum outcome. Since an infant with PKU cannot metabolize breast milk or regular formulas, he must be given a special formula such as "Lofenalac" which is specifically designed for babies with PKU. As the child grows older and begins eating other foods, the parents must carefully calculate and strictly limit the amount of phenylalanine in his diet. This is a difficult diet to follow because phenylalanine is found in very large quantities in high protein foods and in varying amounts in most other foods.

Fortunately, the incidence of this disorder is only 1 in 10,000 to 12,000 births.
