Comparison of patients using lamivudine, entecavir, and tenofovir according to liver fibrosis markers fibrosis-4 and aspartate aminotransferase-to-platelet ratio index scores.

Objectives: It was intended to assess the efficacy of lamivudine, entecavir, and tenofovir regimens in the management of chronic hepatitis B (CHB) guided by Fibrosis-4 (FIB-4) and aspartate aminotransferase-to-platelet ratio index (APRI) scores.

Materials And Methods: Our study was conducted on patients who applied to the hepatitis outpatient clinic between 2008 and 2015 retrospectively. Lamivudine, entecavir, and tenofovir regimens used in the practice of CHB cases were compared by measuring noninvasive FIB tests.

Results: Entirely 199 patients involved in the research were evaluated in three treatment arms; 48 used lamivudine, 46 used entecavir, and 105 used tenofovir. Similar statistical characteristics were observed between research arms regarding age, gender, and alanine aminotransferase normalization by years (P > 0.05). Totally 5 (13.5%) of patients developed Hepatitis B e antigen (HBeAg) seroconversion among 36 HBeAg positivity, and similar statistical features were seen by comparing the groups (P > 0.05). In the entecavir and tenofovir arms, a significant decrease was seen in FIB-4, and APRI index values in the 1st year of treatment (P < 0.001). At the graph curve, a plateau was observed in the APRI test after the 1 year, and a plateau was observed in the FIB-4 test after the 2 year.

Conclusion: Consistent with the study outcome, when we consider FIB regression, tenofovir and entecavir regimens were found more effective than lamivudine. In addition, entecavir was more effective than the other two drugs after the 1 year.
