Abstract
To explore the therapeutic effectiveness of tenofovir alafenamide (TAF) and tenofovir disoproxil fumarate (TDF) on the treatment for chronic hepatitis B (CHB). Retrospectively analyzing 241 cases of chronic hepatitis B patients admitted to our hospital from January 2020 to December 2021, they were divided into a TAF group of 180 cases and a TDF group of 61 cases. The liver function, serum virus markers, clinical efficacy, adverse reactions and cost-effectiveness ratio (CER) analysis of 2 groups were compared. Two groups of patients had no statistically significant difference in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBIL) before treatment. After treatment, the levels of ALT, AST and TBIL were lower than before treatment in both groups (P < .05), but the inter-group difference was not statistically significant (P > .05). After treatment, Hepatitis B surface antigen (HBsAg) conversion rate and Hepatitis B virus DNA (HBV-DNA) conversion rate in the 2 groups had no statistically significant difference. After treatment, the difference in total clinical cure rate between the 2 groups has no statistical significance (P > .05), adverse reactions rate of TAF group was lower than that of TDF group (P < .05). The drug cost median of TAF group was higher than that of TDF (P < .05), but Cost-effectiveness analysis showed the CER of TAF group was similar of TDF group. TAF or TDF therapy can both improve liver function and promote recovery in patients with CHB, achieving the goal of treatment. TAF have more cost but have similar CER to TDF. Moreover, TAF therapy has a higher safety profile.
