277.85, disorders of fatty acid oxidation
E71.311, medium chain acyl CoA dehydrogenase deficiency
Initial symptoms/signs may include:
- Poor feeding
- Lethargy progressing to coma
- Lab findings:
- Elevated ALT and AST
- Liver dysfunction
- Sudden death
- Contact the family and evaluate the infant for related symptoms.
- Provide emergency treatment and referral for symptoms of hypoglycemia, lethargy, and feeding problems.
- Make sure the child eats at regular intervals (every 3 to 4 hours) and formula is available to the family in case breastfeeding becomes insufficient.
- Confirm the diagnosis, work with the following service(s): see all Newborn Screening Programs services providers (1) in our database.
- Evaluate and continue ongoing collaborative management, consult the following service(s): Pediatric Medical Genetics, (801-213-3599); See also Services below.
- Educate the family about signs, symptoms, the need for frequent feedings, and the need for urgent care if 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 a medical ID bracelet for older kids and adults.
- Consider a heart-healthy diet for affected children after 1 year of age.
- Consider oral L-carnitine, which may be recommended in case of deficiency.
- Assist in management of irreversible consequences as necessary, particularly with developmental and educational interventions.
- See the Portal’s diagnosis and management module for MCADD.
