Acute liver failure is associated with mortality of around 50%. The aim of the present studies was to examine the circulatory and metabolic state of the splanchnic region in acute liver failure. This had not been studied previously and it could be expected that improved understanding of the pathophysiology of acute liver failure could lead to improved therapy. ⋯ Exchange of ammonia in muscle tissue was studied in 7 patients with acute liver failure and muscle tissue seems to play a major role in ammonia detoxification in acute liver failure. Treatment with high-volume plasmapheresis decreased arterial ammonia, which was likely due to increased urea production or stimulation of glutamine synthesis in muscle tissue. These findings add to our understanding of the pathophysiology and have implications for the management of acute liver failure.
