It is important for patients with MADD to strictly avoid fasting to prevent hypoglycemia and crises of metabolic acidosis; for this reason, infants and small children should eat frequent meals. Patients with MADD can experience life-threatening metabolic crises precipitated by common childhood illnesses or other stresses on the body, so avoidance of such stresses is critical. Patients may be advised to follow a diet low in fat and protein and high in carbohydrates, particularly in severe cases. Depending on the subtype, riboflavin (100-400 mg/day), coenzyme Q10 (CoQ10), L-carnitine, or glycine supplements may be used to help restore energy production. Some small, uncontrolled studies have reported that racemic salts of beta-hydroxybutyrate were helpful in patients with moderately severe disease; further research is needed.
