Severe neonatal nonketotic hyperglycinemia presents with immediate seizures and poor prognosis. This case highlights treatment resistance to sodium benzoate and dextromethorphan in a neonate with a high glycine index.

Area of Science:

  • Biochemistry
  • Neonatal Medicine
  • Genetics

Background:

  • Nonketotic hyperglycinemia (NKH) is a rare inherited metabolic disorder.
  • It is characterized by glycine accumulation in body fluids.
  • NKH typically presents with severe neurological symptoms and has a poor prognosis.

Observation:

  • A severe case of neonatal nonketotic hyperglycinemia is presented.
  • The neonate experienced immediate seizures post-birth.
  • A high glycine index of 0.38 was recorded.

Findings:

  • The patient exhibited intractable seizures, hypotonia, transient hyperammonemia, and metabolic acidosis.
  • Standard treatments, including sodium benzoate and dextromethorphan, were ineffective.
  • This suggests limited therapeutic options for severe neonatal NKH.

Related Experiment Videos

Implications:

  • This case underscores the variable and severe presentation of neonatal NKH.
  • It highlights the challenges in managing this condition and the need for novel therapeutic strategies.
  • Further research into the pathophysiology and treatment of NKH is warranted.
