Can a UTI cause high ammonia levels?

Among patients with urinary tract infections, but without liver cirrhosis or portal hypertension, production by urea-splitting bacteria and the subsequent tubular reabsorption of ammonia, may result in hyperammonemic encephalopathy. A hyperammonemic state is characterized by an elevated level of ammonia in the blood.

Why does ammonia increase with liver failure?

The increase in blood ammonia in advanced liver disease is a consequence of impaired liver function and of shunting of blood around the liver. Muscle wasting, a common occurrence in these patients, also may contribute since muscle is an important site for extrahepatic ammonia removal.

Neurologic Care in Acute Liver Failure Ammonia is a neurotoxin and an osmotic agent; sustained ammonia levels of 150 to 200 µmol/L (255 to 340 µg/L) greatly increase intraneuronal osmolarity (through its metabolism to glutamine) and the risk for intracranial hypertension and encephalopathy.

There is no antidote for ammonia poisoning. Treatment consists of supportive measures. These include administration of humidified oxygen and bronchodilators and airway management; treatment of skin and eyes with copious irrigation; and dilution of ingested ammonia with milk or water.
