Medical Care

Protein intake is restricted in patients with arginase deficiency. A carefully monitored diet plan is necessary.

Because severe hyperammonemia is unusual, the need for intravenous therapy or hemodialysis is unlikely. In the event that intravenous therapy or hemodialysis is required, the need to omit intravenous arginine from the treatment regimen should be obvious.

Long-term therapy rests on provision of a low-protein diet and, possibly, oral sodium benzoate or sodium phenylbutyrate. A metabolic disease expert should guide the treatment of this rare condition.

Compounds that comprise the urea cycle are sequentially numbered, beginning with carbamyl phosphate (1). At this step, the first waste nitrogen is incorporated into the cycle; N-acetylglutamate exerts its regulatory control on the mediating enzyme, carbamoyl phosphate synthetase (CPS), in this step. Compound 2 is citrulline, the product of condensation between carbamyl phosphate (1) and ornithine (8); the mediating enzyme is ornithine transcarbamylase. Compound 3 is aspartic acid, which is combined with citrulline to form argininosuccinic acid (ASA) (4); the reaction is mediated by ASA synthetase. Compound 5 is fumaric acid generated in the reaction that converts ASA to arginine (6), which is mediated by ASA lyase.
