GPT and Decreased liver function: Prior studies suggest that infants with severe NE are 13 times more likely to have elevated liver enzymes.39 In line with the literature, our study demonstrated a high rate of liver dysfunction in both the mild and moderate/severe groups (45% vs. 67% respectively) with association between the severity of NE based on the Sarnat score and liver dysfunction (AST r = 0.032, ALT r = 0.089 p = 0.022).
