277.85, Disorders of fatty acid oxidation
Initial signs/symptoms in the "early" and "childhood" types may include:
- poor feeding,
- behavior changes,
- extreme sleepiness,
- muscle weakness,
- lethargy, and
- lab findings:
- metabolic acidosis, and
If not treated promptly, patients may experience:
- difficulty breathing,
- muscle weakness with exertion,
- brain damage, and
"Adult" type symptoms may include:
- muscle breakdown,
- muscle aches,
- reddish-brown urine, and
- kidney failure.
- contact the family and evaluate the infant for poor feeding, lethargy, hypotonia, hepatomegaly, or cardiac problems;
- Provide emergency treatment/referral for symptoms of hypoglycemia, arrhythmia, or cardiac decompensation;
- To confirm the diagnosis, work with the following service(s): see all Newborn Screening Programs services providers (4) in our database;
- For evaluation and ongoing collaborative management, consult the following service(s): Division of Pediatric Medical Genetics, (801-581-8943); See also Services below;
- Educate the family regarding signs, symptoms, and the need for urgent care when the infant becomes ill (see VLCADD info for parents (STAR-G) for additional information);
- Assist with implementation of a low-fat, high carbohydrate diet;
- Oral L-carnitine and medium chain triglyceride (MCT) oil supplements may be indicated;
- Cornstarch supplements and avoidance of long chain fatty acids may also be indicated;
- For those identified after irreversible consequences, assist in management, particularly with developmental and educational interventions.
