pyruvate carboxylase deficiency disease/プロリン

The devastating nature of a pyruvate carboxylase deficiency is underscored by the uniformly fatal outcome of the neonatal (French) type and the severely disabling and ultimately fatal outcome of the infantile (North American) type. We report a 7-y-old girl with metabolic and biochemical features of

Amino acids were measured in several regions of autopsied brain from an infant who died with congenital lactic acidosis due to pyruvate carboxylase deficiency (McKusick 26615), as well as in cerebrospinal fluid (CSF) and plasma of four living infants with this disorder. Glutamine content was greatly

A patient with severe pyruvate carboxylase deficiency presented at age 11 weeks with metabolic decompensation after routine immunization. She was comatose, had severe lactic acidemia (22 mM) and ketosis, low aspartate and glutamate, elevated citrulline and proline, and mild hyperammonemia. Head

OBJECTIVE Pyruvate carboxylase (PC) deficiency is a rare metabolic disease. Recently, therapeutic possibilities have been introduced. We aimed to report the largest series of the B type of PC deficiency, focusing on some neurological aspects that have not yet been documented. METHODS We

Two unrelated Canadian Indian infants presented with metabolic acidosis. Lactate, pyruvate, glutamic acid, proline and alanine were greatly elevated in plasma. Urinary excretion of alpha-ketoglutarate and pyruvate was increased. Pyruvate carboxylase activity was very low in skin fibroblasts and

A 10 month old female infant was evaluated for severe lactic acidosis. Clinically she was well nourished and had a substantial amount of adipose tissue despite recurrent episodes of acidosis. Her psychomotor development was retarded, her movements were dystonic and generalized seizures punctuated
