文摘

Liver biopsy is the gold standard to determine the severity of hepatic fibrosis despite its risk and invasiveness. The aspartate aminotransferase/platelet ratio index (APRI) could noninvasively predict the severity of hepatic fibrosis in chronic hepatitis C (CHC) patients. Whether fibrosis index based on four factors (FIB-4) could better predict the severity of hepatic fibrosis than APRI in CHC patients remains inconclusive.

Methods

This retrospective study enrolled 1473 CHC patients (784 men and 689 women) with liver biopsy and clinical data including age, aspartate aminotransferase, alanine aminotransferase, and platelet count. FIB-4 and APRI were calculated with a formula using the four clinical parameters. Hepatic fibrosis was staged using the Metavir classification system.

Results

The areas under the receiver operating characteristics of FIB-4 for the diagnosis of significant fibrosis (≥ F2), advanced fibrosis (≥ F3), and cirrhosis (F4) were 0.816 [95% confidence interval (CI), 0.795–0.836], 0.827 (95% CI, 0.806–0.849), and 0.849 (95% CI, 0.830–0.867), respectively, compared with those of APRI—0.799 (95% CI, 0.778–0.819), 0.791 (95% CI, 0.770–0.812), and 0.802 (95% CI, 0.781–0.922). In addition, the areas under the receiver operating characteristics of FIB-4 were significantly greater than those of APRI for patients with advanced fibrosis and cirrhosis, respectively (p < 0.0001).

Conclusion

FIB-4 could predict hepatic fibrosis in CHC patients. By adding two parameters (age and alanine aminotransferase), FIB-4 better predicts advanced fibrosis and cirrhosis than APRI in CHC patients.
