Abstract
BACKGROUND: Concerns have been raised regarding changes in lipid profiles among patients with chronic hepatitis B (CHB) during tenofovir alafenamide fumarate (TAF) treatment. We aimed to evaluate the effect of TAF treatment on the lipid profiles of patients with CHB. METHODS: A total of 430 patients with CHB from three hospitals were retrospectively included, including 158 patients treated with TAF and 272 patients treated with tenofovir disoproxil fumarate (TDF). RESULTS: In this multicenter cohort, the cumulative incidence of dyslipidemia was notably higher in the TAF group than in the TDF group (P < 0.001). After TAF treatment, a significant elevation was observed in triglyceride (TG) levels (from 0.83 mmol/L to 1.02 mmol/L, P < 0.001) and total cholesterol (TC) levels (from 4.16 mmol/L to 4.32 mmol/L, P < 0.001). Similar changes in TG and TC levels were observed in the TAF group after propensity score matching (PSM). The TG levels (from 0.83 mmol/L to 1.04 mmol/L, P < 0.001) and TC levels (from 4.16 mmol/L to 4.38 mmol/L, P < 0.001) were both increased significantly compared to the baseline levels in the PSM cohort of patients treated with TAF. TAF treatment was independently associated with elevated TG levels (HR = 2.800, 95% CI: 1.334-5.876, P = 0.006) and TC levels (HR = 9.045, 95% CI: 3.836-21.328, P < 0.001). CONCLUSIONS: Compared with TDF treatment, TAF treatment was associated with dyslipidemia in patients with CHB. Close monitoring of lipid profiles is needed in patients with CHB who received TAF treatment.
