    Summary
    This summary is machine-generated.

    Severe transient hyperammonemia in infants, a treatable disorder, affects large premature males. Aggressive treatment, including exchange transfusions, is crucial for survival and normal development.

    Area of Science:

    • Neonatology
    • Pediatric Gastroenterology
    • Metabolic Disorders

    Background:

    • Severe transient hyperammonemia is a critical infant disorder with an unknown cause.
    • Affected infants are often large prematures and male.
    • Birth asphyxia is frequently associated with this condition.

    Purpose of the Study:

    • To describe two infants with severe transient hyperammonemia.
    • To review the literature and summarize 49 cases.
    • To emphasize the need for aggressive treatment regardless of initial ammonia levels.

    Main Methods:

    • Literature review and case series analysis.
    • Summary of 49 cases of severe transient hyperammonemia.
    • Analysis of treatment modalities and outcomes.

    Main Results:

    • Large premature males were most commonly affected.
    • Peak plasma ammonium levels did not predict survival.
    • Exchange transfusions (ET) or ET with peritoneal dialysis resulted in an 83% survival rate.
    • 66% of survivors had normal follow-up examinations.

    Conclusions:

    • Aggressive therapy is essential for infants with severe transient hyperammonemia.
    • Exchange transfusions are an effective treatment modality.
    • Increased awareness and considering hemodialysis may further improve outcomes.
