Nonketotic hyperglycinemia presenting as pulmonary hypertensive vascular disease and fatal pulmonary edema in response to pulmonary vasodilator therapy.

ABSTRACT

The association of pulmonary hypertensive vascular disease with nonketotic hyperglycinemia is rare. We describe 5 infants diagnosed with nonketotic hyperglycinemia, in whom pulmonary hypertensive vascular disease was the main presenting feature, and who developed severe pulmonary edema in response to pulmonary vasodilators.
