Tenofovir alafenamide treatment may not worsen the lipid profile of chronic hepatitis B patients: A propensity score-matched analysis

ABSTRACT

Background/Aims@#Tenofovir alafenamide (TAF) has shown less favorable effect on lipids compared to tenofovir disoproxil fumarate (TDF) in clinical trials. However, data regarding these outcomes in patients with chronic hepatitis B (CHB) are scarce. Therefore, this study aimed to evaluate the effect of TAF on the lipid in patients with CHB. @*Methods@#A total of 237 TAF-treated CHB patients compared with TDF, inactive CHB, and non-hepatitis B virus (HBV)-infected control groups using propensity score matching (PSM). @*Results@#Following PSM, each analysis was conducted on cohorts via the matching of 70140 (TAFTDF), 8989 (TAFinactive CHB), 140560 (TAFnon-HBV infected control), and 3681,472 (TDFnon-HBV-infected control). A significant decrease in the total cholesterol (TC) level was noted at 48 weeks in the TDF group compared to the TAF group (176.3±32.9 vs. 156.7±27.7, P<0.001) and the non-HBV-infected control group (175.0±29.5 vs. 156.2±28.3, P<0.001). However, no significant change in TC was observed in the TAF group and inactive CHB or non-HBV-infected control groups at 48 weeks. For the subgroup analyses of TAF vs. non-HBV-infected control subjects and inactive CHB patients whose detailed lipid profile information were available, no between-group differences in TC, low-density lipoprotein (LDL)-cholesterol, highdensity lipoprotein (HDL)-cholesterol, TC/HDL ratio, and LDL/HDL ratio were observed at 48 weeks. @*Conclusions@#TDF seems to have a lipid-lowering effect compared to the non-HBV-infected control and TAF-treated groups. However, in real practice, TAF might not worsen the lipid profiles of subjects compared to non-HBV-infected controls and patients with inactive CHB.
