Transient nonketotic hyperglycinemia in an asphyxiated patient with pyridoxine-dependent seizures.

ABSTRACT

An asphyxiated neonate with pyridoxine-dependent seizures and associated transient nonketotic hyperglycinemia is reported. Frequent seizures and their resultant hypoxic-ischemic insult may have led to the elevation of the cerebrospinal fluid glycine level in this patient. Early diagnosis and treatment of pyridoxine-dependent seizures is essential for an improved neurologic outcome.
