Abstract
Background
Special diet with restricted branched-chain-amino-acids used for treating maple syrup urine disease can lead to specific amino acid deficiencies.
Case characteristics
We report a neonate who developed skin lesions due to isoleucine deficiency while using specialised formula.
Intervention/Outcome
Feeds were supplemented with expressed breast milk. This caused biochemical and clinical improvement with resolution of skin lesions.
Message
Breast milk is a valuable and necessary adjunct to specialized formula in maple syrup urine disease to prevent specific amino acid deficiency in the neonatal period.
