Ammonia Levels and Hepatic Encephalopathy in Patients with Known Chronic Liver Disease.

J Hosp Med. 2017 Aug;12(8):659-661

Authors: Ninan J, Feldman L

Abstract
Ammonia is predominantly generated in the gut by intestinal bacteria and enzymes and detoxified primarily in the liver. Since the 1930s, ammonia has been identified as the principal culprit in hepatic encephalopathy (HE). Many physicians utilize serum ammonia to diagnose, assess severity, and determine the resolution of HE in patients with chronic liver disease (CLD) despite research showing that ammonia levels are unhelpful in all of these clinical circumstances. HE in patients with CLD is a clinical diagnosis of exclusion that should not be based on ammonia levels.

One thought on “Ammonia Levels and Hepatic Encephalopathy in Patients with Known Chronic Liver Disease.

  1. So true! Additionally, I had a patient with hx ‘elevated ammonia levels’ and family wanted that fixed. No confusion or hx liver disease.
