How might VLCAD deficiency be treated?

Management of VLCAD deficiency depends on the form of the condition present and the specific signs and symptoms in the affected individual. Options may include intravenous glucose as an energy source, treatment of heart rhythm abnormalities, and monitoring for rhabdomyolysis (breakdown of muscle fibers). Heart problems may be reversible with early, intensive supportive care and diet modifications. Individuals with severe forms of the condition are typically placed on a low-fat formula, with supplemental calories provided through medium-chain triglycerides (MCT). Acute rhabdomyolysis may be treated with hydration and alkalization of the urine (decreasing the amount of acid you take in) to protect kidney function and to prevent acute kidney failure. Affected individuals are generally advised to avoid fasting, myocardial irritation (such as cardiac catheterization), dehydration, and a high fat diet.[1]
