[Efficacy and safety of tenofovir amibufenamide in the treatment of patients over 65 years of age with chronic hepatitis B].

Objective: To investigate the efficacy and safety of tenofovir amibufenamide in patients over 65 years old with chronic hepatitis B and liver cirrhosis. Methods: We recruited 45 patients in Linyi People's Hospital with chronic hepatitis B and liver cirrhosis who were treated with TMF antiviral therapy for 48 weeks, compared the virologic response rate and HBV DNA decrease level at 12, 24 and 48 weeks, and the changes in hepatitis B surface antigen, alanine aminotransferase, glomerular filtration rate, creatinine, triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, serum phosphorus and blood lipids, and the changes in ALT normalization rate at 48 weeks. P<0.05 was statistically significant. Results: The age of the enrolled patients was 69.0 (67.0, 72.5) years. At 12, 24, and 48 weeks of treatment, the complete virological response rates were 32.4% (12/37), 70.0% (28/40), and 84.6% (33/39) respectively, and the level of HBV DNA decreased from baseline (P＜0.05). After 48 weeks of treatment, the level of HBsAg decreased (P<0.05), and there was no negative HBsAg conversion and seroconversion. After 48 weeks of treatment, the level of ALT decreased (P<0.05). At 48 weeks of treatment, the rates of ALT reverted to normality were 88.9% (16/18) and 70.4% (19/27), respectively. There was no significant difference in the levels of glomerular filtration rate, creatinine, phosphorus, triglycerides, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol estimated at baseline before and after treatment (P＞0.05), and no serious adverse events were observed. Conclusions: For patients over 65 years old with chronic hepatitis B and liver cirrhosis, TMF can significantly inhibit HBV DNA replication, and the ALT normalization rate is high and well tolerated.
