Summary
Citrullinemia, a urea cycle disorder, was diagnosed in a neonate with severe symptoms. Prompt treatment involving protein restriction and nitrogen waste management improved the infant's condition, highlighting the importance of early diagnosis for long-term outcomes.
Area of Science:
- Biochemistry
- Pediatrics
- Genetics
Background:
- Inborn errors of urea synthesis are rare genetic disorders affecting nitrogen metabolism.
- Citrullinemia is a specific urea cycle disorder characterized by elevated blood citrulline levels.
Observation:
- A four-day-old neonate presented with feeding difficulties, temperature instability, convulsions, and coma.
- Diagnosis of citrullinemia was established based on clinical presentation.
Findings:
- Treatment included protein restriction, exchange transfusions, arginine supplementation, and sodium benzoate for waste nitrogen excretion.
- The neonate achieved a stable clinical and biochemical condition post-treatment.
Implications:
- Early diagnosis and intervention are crucial for improving survival and long-term prognosis in neonates with urea cycle disorders.
- While survival can be prolonged, psychomotor retardation may persist, emphasizing the need for ongoing management and support.
