Study Notes
Inherited Metabolic Disorders
- Most inherited metabolic disorders are associated with severe clinical illness, which often appears soon after birth.
- Symptoms may include intellectual disability and severe neurologic involvement.
- Diagnosis of a specific disorder can be difficult, and treatment may be uncertain.
Prenatal Diagnosis and Newborn Screening
- Prenatal diagnosis is available for many metabolic disorders, but it requires identification of a family at risk.
- Family risk is usually identified only after the birth of an affected child.
- Effective newborn screening programs, advanced diagnostic techniques, and treatment modalities have improved outcomes for many infants.
Identifying Infants at Risk
- Infants suspected of having a metabolic disorder should be referred to centers with expertise in treating these disorders.
- Warning signs include:
- Afebrile for no apparent reason
- Lethargy
- Vomiting
- Respiratory distress
- Seizures
Initial Assessment
- Initial assessment should include:
- Blood gas measurements
- Electrolyte values
- Glucose and ammonia tests
- Urine test for ketones
Advances in Newborn Screening
- Advances in newborn screening technology offer opportunities for:
- Earlier diagnosis
- Prevention of neurologic crisis
- Improved intellectual and physical outcomes
- Tandem mass spectrometry techniques in newborn screening laboratories can detect:
- A broader range of metabolic disorders
- Identification of the disorder
