Abstract
BACKGROUND AND AIMS: The effect of tenofovir amibufenamide (TMF) on blood lipid profiles in patients with chronic hepatitis B (CHB) remains unclear. This study aimed to explore whether TMF affects blood lipids during 48 weeks in patients with CHB. METHODS: A total of 91 patients with CHB undergoing TMF treatment for 48 weeks were divided into two groups: Lipid Normal (n = 42) and Lipid Abnormal (n = 49), based on baseline blood lipid levels. Lipid indices, virological responses, and biochemical indicators were compared between the two groups. Clinical observations were further verified through in vitro experiments. RESULTS: After an average follow-up of 373 ± 121 days, lipid indices in all 91 patients had not significantly changed compared with baseline (total cholesterol: 4.67 vs. 4.69 mmol/L, P = 0.2499; triglycerides: 1.08 vs. 1.04 mmol/L, P = 0.4457; high-density lipoprotein cholesterol: 1.25 vs. 1.25 mmol/L, P = 0.3063; low-density lipoprotein cholesterol: 3.03 vs. 3.02 mmol/L, P = 0.5765). Subgroup comparisons showed lipid indices remained stable. Among treatment-naïve patients (n = 82), complete viral suppression rates were 23.2%, 59.8%, 70.7%, and 86.6% at four, 12, 24, and 48 weeks, respectively. Cellular experiments revealed that TMF did not promote lipid metabolism in primary hepatocytes and AML12 cells. CONCLUSIONS: Regardless of baseline blood lipid characteristics, 48 weeks of antiviral treatment with TMF in patients with CHB had no significant lipid-raising effect.
