Treatment of severe hyperammonemia (serum ammonia levels greater than 1000 μmol/L) should begin with hemodialysis if it is otherwise medically appropriate and tolerated. [ 12 ] Continuous renal replacement therapy (CRRT) is a remarkably effective mode of therapy in neonatal hyperammonemia, particularly in severe cases of Urea cycle defects ...
The treatment goal for individuals affected with OTC deficiency is the avoidance of hyperammonemia. This can be accomplished through a strictly controlled low-protein diet, as well as preventative treatment with nitrogen scavenging agents such as sodium benzoate .
Carglumic acid, sold under the brand name Carbaglu among others, is used for the treatment of hyperammonaemia. [3] [6] [7] Carglumic acid is a carbamoyl phosphate synthetase 1 (CPS 1) activator.
Ornithine translocase deficiency, also called hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome, [1] is a rare autosomal recessive [2] urea cycle disorder affecting the enzyme ornithine translocase, which causes ammonia to accumulate in the blood, a condition called hyperammonemia.
A blood ammonia test is essential to uncover elevated ammonia levels (hyperammonemia), the classic sign of a urea cycle disorder. Resources on recognizing and testing for hyperammonemia are featured on the campaign website, checkammonia.com. Quickly diagnosing UCDs is critical.
Infusions with high-concentration glucose should also be avoided as it may exacerbate hyperammonemia. [40] [41] In serious cases where patients do not respond well to treatment, liver transplantation may be required as a final solution and has been shown to correct the metabolic disturbances caused by citrin deficiency. [42] [43] [44]
Sodium phenylbutyrate is taken orally or by nasogastric intubation as a tablet or powder, and tastes very salty and bitter. It treats urea cycle disorders, genetic diseases in which nitrogen waste builds up in the blood plasma as ammonia glutamine (a state called hyperammonemia) due to deficiences in the enzymes carbamoyl phosphate synthetase I, ornithine transcarbamylase, or argininosuccinic ...
