Serum analyte pattern characteristic of fulminant hepatic failure.
Fulminant hepatic failure (FHF) is a poorly understood condition in which total liver failure occurs and is thought to be caused by a variety of conditions including Reye's syndrome, hepatitis, drug overdoses, and vascular insufficiency. While this condition is an uncommon one, it carries with it a high fatality rate and must therefore be diagnosed as rapidly as possible. Six patients have been observed over a two-year period with biopsy and/or autopsy-confirmed FHF: one with acute hepatitis B-delta; three with histories of alcoholism, two of them with cirrhosis; one with acute tylenol overdose; and one with hepatic vascular insufficiency. All of these patients, except one, exhibited a rapid, fatal downhill course after onset of symptoms. In all of these patients, a consistent elevation was observed in serum levels of aspartate aminotransferase (AST) or serum glutamate oxaloacetate transaminase (SGOT) and alanine aminotransferase (ALT) or serum glutamate pyruvate transaminase (SGPT) such that the ratio of AST to ALT was significantly greater than 1 and in serum levels of ammonia. Other liver function tests were found to be abnormal but not in so consistent a pattern, although total protein and albumin were found to be significantly decreased in all of these patients. The stereotypical elevation of the transaminases with high AST-to-ALT ratios and the rise in ammonia appear to characterize this life-threatening illness most reliably.
