Which condition is indicated by an elevation in both ALT and AST in lab findings?

An elevation in both alanine aminotransferase (ALT) and aspartate aminotransferase (AST) is primarily indicative of liver conditions, as these enzymes are found in high concentrations in the liver. In the context of non-alcoholic steatohepatitis (NASH), the liver is subjected to inflammation and damage due to the accumulation of fat, leading to significantly elevated ALT and AST levels.

In NASH, the ALT levels are often higher than AST levels, but both can still be elevated. This follows the pattern of liver cell injury associated with this condition, distinguishing it from other liver-related conditions.

This elevated enzyme activity suggests hepatocellular injury, which is characteristic of NASH, reflecting the balance of liver damage and fatty infiltration. Other options may present with elevation of these enzymes, but the specific context of fatty liver disease and its association with metabolic syndromes clearly aligns with NASH as the correct condition represented by the lab findings of elevated ALT and AST levels.
