Antepartum Ornithine Transcarbamylase Deficiency
نویسندگان
چکیده
Ornithine transcarbamylase deficiency (OTCD) is the most common type urea cycle enzyme deficiencies. This syndrome results from a deficiency of the mitochondrial enzyme ornithine transcarbamylase, which catalyzes the conversion of ornithine and carbamoyl phosphate to citrullin. Our case was a 28-year-old female diagnosed with OTCD following neurocognitive deficit during her first pregnancy. Although hyperammonemia was suspected as the cause of the patient's mental changes, there was no evidence of chronic liver disease. Plasma amino acid and urine organic acid analysis revealed OTCD. After combined modality treatment with arginine, sodium benzoate and hemodialysis, the patient's plasma ammonia level stabilized and her mental status returned to normal. At last she recovered without any damage left.

Under recognition of late onset ornithine transcarbamylase deficiency.
Late onset ornithine transcarbamylase deficiency (McKusick 311250) is reported in four Finnish patients, two boys and two heterozygous girls. The subtle onset and course of ornithine transcarbamylase deficiency emphasises the need for plasma ammonia and amino acid measurements in clinical situations suggesting a disorder of this nature.

Human ornithine transcarbamylase is a trimer with 46% amino acid sequence homology to the catalytic subunit of E coli aspartate transcarbamylase. Secondary structure predictions, distributions of hydrophilic and hydrophobic regions, and the pattern of conserved residues suggest that the three dimensional structures of the two proteins are likely to be similar. A three dimensional model of ornit...
متن کاملHyperammonemic coma due to parenteral nutrition in a woman with heterozygous ornithine transcarbamylase deficiency.
Ornithine transcarbamylase deficiency is an X-linked disorder of the urea cycle that can cause hyperammonemic encephalopathy in hemizygous males and heterozygous females. Affected females typically limit protein intake in their diet. This case report describes a 36-year-old woman with ulcerative colitis who went into hyperammonemic coma after administration of total parenteral nutrition. A simi...

BACKGROUND Neurological complications following bariatric surgery are rare. Whereas nutritional deficiencies are the most common cause of neurological symptoms, the unmasking of previously subclinical metabolic disorders can also lead to significant morbidity. OBJECTIVE To characterize the clinical presentation, serum biochemical fluctuations, and functional enzymatic analysis of a case of fu...
متن کاملSevere ornithine transcarbamylase deficiency. Two and a half years' survival with normal development.
The clinical course and management of a boy with severe ornithine transcarbamylase deficiency are described. In addition to treatment with sodium benzoate and amino acid keto analogues, mannitol may be useful in hyperammonaemia and nocturnal gavage feeding aids maintenance treatment.
