Differential Intraoperative Effect of Liver Transplant in Different Inborn Errors of Metabolism.

Liver transplant (LT) is a therapeutic option for a growing number of inborn errors of metabolism (IEM), including some disorders not confined to the liver. Clinical advantages of LT in maple syrup urine disease (MSUD), methylmalonic acidemia (MMA), and argininosuccinic aciduria (ASA) have been reported. However, no information on the early metabolic effect of LT after portal reperfusion is available in these disorders.

Differential response to renal replacement therapy in neonatal-onset inborn errors of metabolism.

Severe urea cycle defects (UCD), organic acidemias (OA) and maple syrup urine disease (MSUD) are life-threatening disorders presenting in the first days of life. Renal replacement therapy (RRT) is an emergency option in affected newborns, mostly performed as ultima ratio. We report our 10-year experience using emergency RRT in newborns with UCD, OA and MSUD.
