Urea Cycle Disorder
ثبت نشده
چکیده
RATIONALE. With no effective clearance system for ammonia, levels increase rapidly, resulting in cerebral edema with severe neurologic compromise. Dialysis is the only means of rapid removal of ammonia from blood in acute neonatal hyperammonemia, and hemodialysis is preferred over peritoneal dialysis because it is much more effective. If hemodialysis is not available, hemofiltration can be used, although ammonia removal may be slower.

Nonhepatic hyperammonemic encephalopathy due to undiagnosed urea cycle disorder.
Ornithine transcarbamoylase deficiency is the most common inherited urea cycle disorder. In adults, its phenotypes are diverse. In asymptomatic patients with late presentations, symptom onset is often associated with a precipitating factor. We present a case of a woman with urea cycle disorder diagnosed after an acute peptic ulcer bleed and fasting.
متن کاملLate-onset ornithine transcarbamylase deficiency: An under recognized cause of metabolic encephalopathy
INTRODUCTION Ornithine transcarbamylase deficiency is the most common inherited disorder of the urea cycle, has a variable phenotype, and is caused by mutations in the OTC gene. We report three cases of ornithine transcarbamylase deficiency to illustrate the late-onset presentation of this disorder and provide strategies for diagnosis and treatment. The patients were maternal first cousins, pre...
متن کاملA Newborn with Propionic Acidemia Mimicking Urea Cycle Defect
Neonatal-onset propionic acidemia is the most common form of disorder. A 9-days old new born admitted to our hospital with lethargy suggested urea cycle defect at first look due to lack of metabolic acidosis, normal ketone and anion gap in laboratory evaluations. The case mimicking urea cycle defect, which was diagnosed as neonatal-onset propionic acidemia by specific tests, was presented becau...
متن کاملMutation analysis of Indian patients with urea cycle defects.
Molecular testing for a specific metabolic disorder remains the gold standard due to its high specificity and sensitivity and possibility of accurate prenatal diagnosis. We report four cases of urea cycle defect where mutational analysis of the involved genes was performed and subsequently, prenatal diagnosis could be offered to one of the family.

A 4-year-old girl presented at our clinic with autistic-like symptoms, aggressivity and occasional hyperactivity. She had no history of neurologic or physical symptoms. Her condition was diagnosed as pervasive developmental disorder not otherwise specified, according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). She received pharmacologic...

We report a 50 hour old newborn with inborn urea cycle disorder and hyperammonia of 2320 umol/L. The pharmacological treatment of the first metabolic crisis was combined with venovenous hemodiafiltration and therapeutic hypothermia to rescue the patient from a life-threatening cerebral edema.
