277.85, Disorders of fatty acid oxidation
Initial symptoms/signs may include:
- poor feeding,
- lethargy progressing to coma,
- lab findings:
- hyperammonemia, and
Subsequent symptoms/signs may include:
- liver dysfunction,
- encephalopathy, and
- sudden death.
- Contact the family and evaluate the infant for related symptoms
- Provide emergency treatment/referral for symptoms of hypoglycemia, lethargy, feeding problems
- To confirm the diagnosis, work with the following service(s): Utah Newborn Screening Program, (801-584-8256); See also Services below
- For evaluation and ongoing collaborative management, consult the following service(s): Medical Genetics, (801-231-3599); See also Services below
- Educate the family regarding signs, symptoms, the need for frequent feedings, and the need for urgent care when the infant becomes ill (see MCADD info for parents (STAR-G) for additional information); provide an "emergency" letter guiding caregivers in the appropriate response to acute illness (and an MedicAlert bracelet for older kids and adults)
- Frequent, low fat, high carbohydrate meals and snacks may be indicated for affected children
- Glucose may be indicated during hypoglycemic episodes
- Oral L-carnitine may be recommended for some children
- For those identified after irreversible consequences, assist in management, particularly with developmental and educational interventions
- See also the Diagnosis Module on MCADD
