ABSTRACT
OBJECTIVE:
Liver stiffness measurements (LSMs) and controlled attenuation parameters (CAPs) obtained using vibration-controlled transient elastography (VCTE) are recognized non-invasive methods of assessing liver histology. The usefulness of CAP for predicting liver-related events (LREs hepatocellular carcinoma, decompensation, bleeding varices) is not well understood worldwide. Our aim was to re-evaluate the cutoff values of LSM/CAP in Japan and to examine whether LSM/CAP can predict LRE.METHODS:
Japanese NAFLD patients (n = 403) who underwent both liver biopsy and VCTE were enrolled. We determined optimal cutoff values of LSM/CAP diagnoses for fibrosis stage and steatosis grade and investigated their clinical outcome based on LSM/CAP values.RESULTS:
The LSM cutoff values for F1 to F4 are 7.1, 7.9, 10.0 and 20.2 kPa, and the CAP cutoff values for S1 to S3 are 230, 282 and 320 dB/m. During a median follow-up of 2.7 y (range 0.0-12.5 y), 11 patients developed LREs. The incidence of LREs in the LSM Hi (≥8.7) group was significantly higher than that in the LSM Lo (<8.7) group (p = 0.003), and the incidence in the CAP Lo (<295) group was higher than that in CAP Hi (≥295) group (p = 0.018). Considering LSM and CAP together, the risk of LRE was higher in the LSM Hi CAP Lo group than in the LSM Hi CAP Hi group (p = 0.03).CONCLUSION:
We set LSM/CAP cutoff values to diagnose liver fibrosis and steatosis in Japan. Our study determined that NAFLD patients with high LSM and low CAP values are at high risk for LREs.Palabras clave
