Tenofovir Disoproxil Fumarate Versus Entecavir: Effects on Lipid Profiles and Cardiovascular Outcomes in People Living With Chronic Hepatitis B

초록

While entecavir (ETV) and tenofovir disoproxil fumarate (TDF) effectively manage chronic hepatitis B, their long-term effects on lipid metabolism and cardiovascular outcomes remain unclear. This study compares the impact of ETV, TDF, and treatment-na & iuml;ve (control group) on hyperlipidemia and major adverse cardiac events (MACE) in people living with chronic hepatitis B (PLWHB). We used claim data from the South Korean National Health Insurance Service. Propensity score matching was used to account for confounding factors. The 5-year cumulative incidence of dyslipidemia was 7.10% for TDF, 12.17% for ETV, and 18.55% for the control group, with incidence rates per 1000 person-years of 14.5, 25.5, and 38.9, respectively. TDF showed a significantly lower risk of dyslipidemia compared to ETV (IRR: 0.56, p < 0.001) and the control group, which was confirmed in Cox regression analysis (HR: 0.392 vs. control, p < 0.001). For MACE, the 5-year cumulative incidence was 9.11% for TDF, 10.98% for ETV, and 12.32% for the control group, with incidence rates per 1000 person-years of 18.4, 22.5, and 24.8, respectively. TDF demonstrated a reduced risk compared to ETV (IRR: 0.817, p < 0.001), which was similarly supported by Cox regression analysis (HR: 0.728 vs. control, p < 0.001). In conclusion, TDF not only reduces the risk of hyperlipidemia but is also associated with a reduced risk of MACE compared to ETV or treatment-naive group in PLWHB.
