BACKGROUND The efficacy and safety profile of tenofovir amibufenamide(TMF)in chronic hepatitis B(CHB)patients is not well-established.AIM To compare the efficacy and safety of TMF and tenofovir alafenamide(TAF)over a 48-wk period in patients with CHB.METHODS A total of 215 subjects meeting the inclusion criteria were enrolled and divided into two groups:TMF group(n=106)and the TAF group(n=109).The study included a comparison of virological response(VR):Undetectable hepatitis B virus DNA levels,alanine transaminase(ALT)normalization rates,renal function parameters,and blood lipid profiles.RESULTS At 24 and 48 wk,VR rates for the TMF group were 53.57%and 78.57%,respectively,compared with 48.31%and 78.65%for the TAF group(P>0.05).The VR rates were also similar in both groups among patients with low-level viremia,both hepatitis B e antigen(HBeAg)-positive and HBeAg-negative subgroups.The TMF cohort showed ALT normalization and renal safety profiles similar to the TAF group.There was a notable increase in total cholesterol levels in the TAF group(P=0.045),which was not observed in the TMF group(P>0.05).In patients with liver cirrhosis,both groups exhibited comparable VR and ALT normalization rates and renal safety profiles.However,the fibrosis 4 score at 48 wk showed a significant reduction in the TAF group as compared to the TMF group within the liver cirrhosis subgroup.CONCLUSION Our study found TMF is as effective as TAF in treating CHB and has a comparable safety profile.However,TAF may be associated with worsening lipid profiles.
