Insights

Shear wave elastography (SWE) effectively predicts liver fibrosis in hepatitis C virus (HCV) patients, including those coinfected with HIV. Combining SWE with the FIB-4 score enhances accuracy for assessing liver fibrosis stages.

Area of Science:

  • Hepatology
  • Medical Imaging
  • Diagnostic Accuracy

Background:

  • Chronic hepatitis C virus (HCV) infection can lead to liver fibrosis.
  • Previous studies on shear wave elastography (SWE) for liver fibrosis assessment excluded HIV/HCV-coinfected patients.
  • Noninvasive methods are crucial for evaluating liver fibrosis in HCV patients.

Purpose of the Study:

  • To evaluate the diagnostic performance of SWE for liver fibrosis in HCV patients, including monoinfected and coinfected individuals.
  • To compare SWE's accuracy with liver biopsy as the reference standard.
  • To assess the utility of combining SWE with the FIB-4 score.

Main Methods:

  • Liver stiffness was measured using SWE in 80 patients with HCV undergoing liver biopsy (METAVIR staging).
  • Diagnostic performance was assessed using receiver operating characteristic (ROC) curves.
  • Cutoff values for different fibrosis stages were determined.

Main Results:

  • A significant correlation was found between liver stiffness and fibrosis stage (ρ = 0.685, P < .001).
  • High diagnostic accuracy was achieved for distinguishing various fibrosis stages (AUROCs up to 0.975).
  • No significant difference in liver stiffness was observed between monoinfected and coinfected patients, suggesting shared cutoff values.

Conclusions:

  • Liver SWE is an effective noninvasive tool for predicting liver fibrosis in HCV patients.
  • Monoinfected and coinfected patients can utilize the same SWE cutoff values.
  • Combining SWE with the FIB-4 score improves accuracy but may increase inconclusive results.
