Abstract

Background: Liver stiffness measurement (LSM) can assess liver fibrosis in patients with chronic hepatitis B (CHB). We evaluated whether LSM can be used to assess changes in liver fibrosis during antiviral treatment using nucleos(t)ide analogs in patients with CHB. Methods: We recruited 41 patients with CHB who had significant liver fibrosis, normal or slightly elevated serum alanine aminotransferase (ALT) levels (≤2 × upper limit of normal), and detectable serum hepatitis B virus DNA before antiviral treatment. Patients in Group 1 (n = 23) and Group 2 (n = 18) underwent follow-up LSM after antiviral treatment for 1 and 2 years, respectively. Results: The mean age, ALT and LSM value of all patients (34 men and 7 women) before antiviral treatment were 46.6 ± 9.5 years, 40.6 ± 17.2 IU/L and 12.9 ± 8.6 kPa, respectively. Hepatitis B e antigen (HBeAg) was detected in 31 patients (75.6%). Fibrosis stage was F2 in 12 (29.3%), F3 in 6 (14.6%) and F4 in 23 (56.1%) patients. After antiviral treatment, LSM values and DNA positivity decreased significantly as compared to baseline (P = 0.018 and P < 0.001 in Group 1; P = 0.017 and P < 0.001 in Group 2, respectively), whereas ALT levels were unchanged (P = 0.063 in Group 1; P = 0.082 in Group 2). Conclusions: Our preliminary data suggest that LSM can be used to assess liver fibrosis regression after antiviral treatment using nucleos(t)ide analogs in patients with CHB.
