Early Liver Transplantation for Neonatal-Onset Methylmalonic Acidemia.
With conventional dietary treatment, the clinical course of methylmalonic acidemia due to cobalamin-unresponsive methylmalonyl-CoA mutase (MCM) deficiency is characterized by the persistent risk of recurrent life-threatening decompensation episodes with metabolic acidosis, hyperammonemia, and coma. Liver transplant has been proposed as an alternative treatment and anecdotally attempted in the l...
متن کاملMethylmalonic acidemia with the unusual complication of severe hyperglycemia.
We describe a case of neonatal methylmalonic acidemia with the unusual complication of severe, insulin-resistant hyperglycemia. Methylmalonic acidemia, an inherited metabolic disease affecting the catabolism of propionic acid, is manifested by persistent metabolic acidosis, urinary excretion of large amounts of methylmalonic acid, and occasionally by hypoglycemia. Severe and persistent metaboli...
متن کاملMethylmalonic acidemia
The authors provide an overview of the hereditary methylmalonic acidemias, a group of metabolic disorders with varied clinical presentations. This includes the most severe form of L-methylmalonyl-CoA mutase deficiency, termed mut(o) methylmalonic acidemia, which, together with the less severe deficiencies of L-methylmalonyl-CoA mutase, are the most common causes of methylmalonic acidemia. They ...
متن کاملMethylmalonic Acidemia.
Methylmalonic Acidemia (MMA) is an inborn error of metabolism that results in accumulation of methylmalonic acid in blood and increased excretion in urine. The effects of MMA vary from mild to life threatening and it usually presents in early infancy. Affected infants can have vomiting, dehydration, hypotonia, developmental delay and failure to thrive. The emergency treatment of the newborn wit...
متن کاملOptic neuropathy in methylmalonic acidemia and propionic acidemia.
BACKGROUND Methylmalonic acidemia (MMA) and propionic acidemia (PA) are rare hereditary disorders of protein metabolism, manifesting early in life with ketoacidosis and encephalopathy and often resulting in chronic complications. Optic neuropathy (ON) has been increasingly recognised in both conditions, mostly through isolated case reports or small cases series. We here report the clinical feat...
