To assess the values of liver stiffness (LS) in patients with hepatitis B virus (HBV) chronic hepatitis and to compare them with those in patients with hepatitis C virus (HCV) chronic hepatitis.


The study included 140 patients with HBV chronic hepatitis, and 317 patients with HCV chronic hepatitis, in which LS was measured (FibroScan®-Echosens®) and liver biopsy was performed in the same session (assessed according to the Metavir score).


According to the Metavir score of the 140 HBV patients: one had F0, 32 had F1, 67 had F2, 33 had F3 and 7 had F4. Of the 317 HCV patients: 5 had F0, 34 had F1, 146 had F2, 93 had F3 and 39 had F4. For the same severity of fibrosis, the mean values of LS in HBV patients were similar to those in HCV patients: F1, 6.5 ± 1.9 kPa vs 5.8 ± 2.1 kPa (P = 0.0889); F2, 7.1 ± 2 kPa vs 6.9 ± 2.5 kPa (P = 0.3369); F3, 9.1 ± 3.6 kPa vs 9.9 ± 5 kPa (P = 0.7038); F4, 19.8 ± 8.6 kPa vs 17.3 ± 6.1 kPa (P = 0.6574). A significant direct correlation between LS measurements and fibrosis was found in HCV patients (Spearman's r = 0.578, P < 0.0001), as well as in HBV patients (r = 0.408, P < 0.0001). The correlation was more significant in HCV than in HBV patients (Fisher's Z-test, Z = 2.210, P = 0.0271).


In our group, the mean values of LS in patients with chronic B hepatitis were similar to those in patients with chronic HCV hepatitis, for the same stage of fibrosis. Also, LS was correlated with the severity of fibrosis both in HBV and HCV chronic hepatitis patients.
