Leigh's necrotizing encephalopathy with pyruvate carboxylase deficiency. 1983

E F Gilbert, and S Arya, and R Chun

Infants with subacute necrotizing encephalopathy or Leigh's encephalopathy usually are first examined before the age of 2 years with degenerative neurologic disease with variable clinical appearance. Necrotizing lesions of the CNS occur with special predilection of the gray matter. Biochemical defects of thiamine triphosphate associated with an inhibitor of the enzyme thiamine pyrophosphate-adenosine triphosphate phosphoryltransferase and deficiency of the enzyme pyruvate carboxylase have been found. Progressive neurologic deterioration and death occurred in an infant with pyruvate carboxylase deficiency. Pathologic studies showed extensive necrotizing areas of the gray matter, mamillary bodies, and midbrain and basal ganglia. Biochemical studies on the liver confirmed a deficiency of pyruvate carboxylase.

UI	MeSH Term	Description	Entries
D007223	Infant	A child between 1 and 23 months of age.	Infants
D009336	Necrosis	The death of cells in an organ or tissue due to disease, injury or failure of the blood supply.
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D001927	Brain Diseases	Pathologic conditions affecting the BRAIN, which is composed of the intracranial components of the CENTRAL NERVOUS SYSTEM. This includes (but is not limited to) the CEREBRAL CORTEX; intracranial white matter; BASAL GANGLIA; THALAMUS; HYPOTHALAMUS; BRAIN STEM; and CEREBELLUM.

D015324	Pyruvate Carboxylase Deficiency Disease	An autosomal recessive metabolic disorder caused by absent or decreased PYRUVATE CARBOXYLASE activity, the enzyme that regulates gluconeogenesis, lipogenesis, and neurotransmitter synthesis. Clinical manifestations include lactic acidosis, seizures, respiratory distress, marked psychomotor delay, periodic HYPOGLYCEMIA, and hypotonia. The clinical course may be similar to LEIGH DISEASE.
