Child with Phenylketonuria (PKU)

Marcie M. is an active 3 year old with blond hair and blue eyes. She is the only child in her family. At birth she weighed 5-1/2 lbs. After several feedings, a routine screening test for phenylketonuria was positive. She was retested at 2 weeks and again at 4 weeks. Each test was positive, blood phenylalanine was 30mg/dl and phenylpyruvic acid was identified in her urine.

With the diagnosis of PKU at age 2 weeks, she was started on Lofenalac year of life. She was seen at frequent intervals for phenylalanine measurements and formula adjustment. Her mother has been very careful in controlling her diet and making adjustments as indicated by her increased growth needs. Now, at this progress visit at age 3, she appears to be a healthy well-adjusted child. Her blood test reveals a phenylalanine level of 6 mg/dl. She weighs 35 lbs. and is 42” tall. She is well-nourished, alert and happy.

Marcie’s mother asked about the possibility of modifying her diet. Marcie has become interested in the different foods eaten by her playmates at the nursery school she attends and wants to eat like them. The children offer her foods that she should not eat. The pediatrician recommended Mrs. M find a very good nursery school where she can be confident that Marcie’s diet will be followed and her activity with her playmates monitored so that she will not get food she should not have.
