Liver tissue alterations other than fibrosis may have an impact on liver stiffness measurement. In this study we evaluated 18 patients without a previous clinical history of liver disease, consecutively admitted for acute viral hepatitis. In each patient, aminotransferase determination and liver stiffness measurement were performed on the same study day, at 3 different points: (1) peak increase in aminotransferase; (2) aminotransferase 50% or less of the peak; (3) aminotransferase levels ≤2× the upper limit of normal. In all patients, the degree of liver stiffness at the time of the peak increase in aminotransferases exceeded the cutoff values proposed for the prediction of significant fibrosis or cirrhosis. A progressive significant reduction in liver stiffness values was observed (P < 0.0001) in the follow‐up period in parallel with the reduction of aminotransferase levels (P < 0.0001). Moreover, a statistically significant, positive …
