Initial signs/symptoms in the early and childhood types may include:
- Poor feeding
- Behavior changes
- Extreme sleepiness
- Muscle weakness
- Lab findings:
- Metabolic acidosis
- Difficulty breathing
- Muscle weakness with exertion
- Brain damage
- Muscle breakdown with exercise or prolonged fasting
- Muscle aches
- Reddish-brown urine
- Kidney failure
- Contact the family and evaluate the infant for poor feeding, lethargy, hypotonia, hepatomegaly, or cardiac problems.
- Recommend frequent feeding (every 3 to 4 hours in infants), including at night.
- Provide emergency treatment and referral for symptoms of hypoglycemia, arrhythmia, or cardiac decompensation.
- Confirm the diagnosis, work with the following service(s): we currently have no Newborn Screening Programs service providers listed, please search our Services database for related services.
- Evaluate and continue ongoing collaborative management, consult the following service(s): we currently have no Pediatric Genetics service providers listed, please search our Services database for related services.
- Educate the family about signs, symptoms, and the need for urgent care if the infant becomes ill (see VLCADD - Information for Parents (STAR-G) for additional information).
- Assist with implementation of a low-fat diet supplemented with medium chain triglycerides if necessary.
- Consider oral L-carnitine and medium chain triglyceride (MCT) oil supplements.
- Assist in management of irreversible consequences as necessary, particularly with developmental and educational interventions.
- See the Portal’s diagnosis and management module for VLCADD.
