Transient Hyperammonemias in Infants with and without Organic Acidemia
Transient hyperammonemia of the newborn was first described in 1978 in 5 preterm infants1. During that period this disorder appeared in our experience to be the most common form of symptomatic neonatal hyperammonemia. More recently, we have not studied a patient with this disorder in more than 2 years, while the number of patients referred to us for diagnosis of hyperammonemia has increased. Whether these observations reflect a real changing incidence of the disorder remains to be determined.
