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...
متن کاملOrthotopic liver transplantation for ornithine transcarbamylase deficiency with hyperammonemic encephalopathy.
Ornithine transcarbamylase (OTC) deficiency is an X chromosome-linked disorder causing hyperammonemic encephalopathy with a very poor prognosis. We describe here two patients with OTC deficiency, one a late on-set female patient (case 1) and the other a neonatal-onset male patient (case 2), who were successfully treated with orthotopic liver transplantation (OLTx). The OTC activity in the excis...
متن کاملFatal hyperammonaemia due to late-onset ornithine transcarbamylase deficiency.
In this case report we describe a 67-year-old male, admitted to the ICU with pneumonia who unexpectedly developed a fatal coma due to hyperammonaemia. At postmortem the diagnosis late-onset ornithine transcarbamylase deficiency was made. The non-specific clinical presentation, the rapid deterioration and incidentally the fatal outcome all underline the importance of recognition and knowledge of...
متن کاملOrnithine Transcarbamylase Deficiency
Accumulation of ammonia in body tissues most commonly occurs in hepatic failure. However, it may also result from a specific deficiency of an enzyme of the urea cycle (Fig., 1). Severe hyperammonaemia has been reported with deficiencies of carbamyl phosphate synthetase (Freeman et al., 1964) and ornithine transcarbamylase (Russell et al., 1962; Levin and Russell, 1967). Some increase in blood a...
