Liver Stiffness Measurement Interpretation

Clinical Significance by Disease Etiology

• The American Gastroenterological Association (AGA) recommends a cutoff of 12.5 kPa for diagnosing cirrhosis in patients with hepatitis C, and a value of 6.02 kPa is significantly below this threshold, suggesting absence of cirrhosis in HCV patients 1, 2
• In chronic hepatitis B, the AGA suggests a cutoff of 11.0 kPa to detect cirrhosis, and a measurement of 6.02 kPa is well below this threshold, indicating absence of cirrhosis in HBV patients 3
• For alcoholic liver disease, a cutoff of 12.5 kPa is used to diagnose cirrhosis, and at 6.02 kPa, this value suggests minimal to no fibrosis in patients with alcoholic liver disease 4, 5, 6
• In autoimmune hepatitis patients achieving biochemical remission, an average liver stiffness of 6.4 ± 3.2 kPa has been observed, and a value of 6.02 kPa is consistent with well-controlled disease in autoimmune hepatitis patients 7

Reliability and Interpretation Considerations

• When interpreting liver stiffness measurements, it is essential to consider the clinical context, laboratory values, and imaging findings, as recommended by the American Gastroenterological Association (AGA) 1
