Real-life impact of tenofovir disoproxil fumarate and entecavir therapy on lipid profile, glucose, and uric acid in chronic hepatitis B patients.

Abstract

The impact of long-term nucleos(t)ide analogs treatment on host metabolism is a concern. Hence, we conducted this study to compare the effect of entecavir (ETV) and tenofovir disoproxil fumarate (TDF) on metabolic parameters among chronic hepatitis B(CHB) patients.In this real-life retrospective study, 2030 CHB outpatients treated with ETV or TDF at Nanfang Hospital, China, were included. For treatment-naïve patients, pretreatment and semiannual metabolic parameters were collected. For treatment-experienced patients, metabolic parameters were collected at the first visit. Propensity score matching (PSM) was used to balance the effects of potential confounding factors.Among 122 treatment-naïve patients and 1908 treatment-experienced patients, ETV-treated patients were older with a higher percentage of metabolic syndrome. After PSM, the characteristics were comparable between the two groups. For treatment-naïve patients, four lipid parameters, including total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein, and triglyceride levels showed a decreasing trend during the 42-month TDF treatment, while they remained relatively stable or increased during ETV treatment. At Month 30, the levels of TC and LDL among TDF-treated patients were significantly lower than those among ETV-treated patients (TC: 4.7 mmol/L vs. 3.9 mmol/L, p = 0.004; LDL: 3.0 mmol/L vs. 2.4 mmol/L, p = 0.009). For treatment-experienced patients, we also observed lower levels of lipid parameters in patients with different durations of TDF treatment. The levels of glucose and uric acid were similar among ETV- and TDF-treated patients.TDF has a lipid-lowering effect in CHB patients, which provides a basis for the selection of antiviral drugs for aging CHB patients.
