What triggers rhabdomyolysis in CPT2 deficiency?

Prolonged exercise (>30-60 min), prolonged fasting, fever, cold exposure, and anesthesia can all trigger rhabdomyolysis in CPT2; the adult myopathic form is the most common FAO disorder presenting in adulthood.

What CK level indicates high AKI risk from rhabdomyolysis?

CK >15,000-20,000 IU/L requires aggressive IV fluid hydration; CK >50,000 IU/L warrants hospitalization with high-volume saline infusion to prevent myoglobinuric acute kidney injury.

Is dietary fat restriction needed in adult CPT2 myopathic form?

Moderate reduction in long-chain fat and addition of MCT oil; pre-exercise carbohydrate loading is most effective; complete fat restriction is not practical or necessary in the myopathic form.

Can patients with CPT2 take statins?

Statins inhibit the same coenzyme A pathway used by CPT2 for fatty acid transport; combined with CPT2 deficiency, statin myopathy risk is elevated; statins should be used with extreme caution if at all.

Is there a neonatal form of CPT2 deficiency?

The severe neonatal form has hypoketotic hypoglycemia, cardiomyopathy, liver disease, renal cystic dysplasia, and neuronal migration defects; it is usually lethal in infancy. The myopathic adult form is entirely different in presentation.
