BACKGROUND Taiwan has a high prevalence of hepatitis B virus (HBV) infection. HBV-related end-stage liver disease is the leading cause of liver transplantation (LT). Tenofovir alafenamide (TAF) is a recently approved agent for the treatment of chronic HBV infection that improves renal profiles compared with tenofovir disoproxil fumarate (TDF) in phase III trials. This study aimed to assess the outcomes of TAF treatment in LT recipients. MATERIAL AND METHODS This retrospective study analyzed 17 LT recipients who underwent treatment with TDF and TAF. Changes in baseline renal function were compared. RESULTS Seventeen LT recipients received TDF for ≥48 weeks and were switched to TAF. During TDF treatment, estimated glomerular filtration rate (eGFR) (using the Modification of Diet in Renal Disease [MDRD] formula) decreased significantly at weeks 24 and 48. At week 48, only 2 patients (11.8%) displayed improved renal function, whereas the other patients showed decreased eGFR ranging from 5.48% to 62.84%. After switching to TAF, the median eGFR increased by 3.01% at week 24 and decreased by 0.31% at week 48. Seven patients (47%) showed improved renal function at week 48 after TAF treatment. CONCLUSIONS Switching from TDF to TAF was associated with fewer short-term renal impairment while maintaining the antiviral efficacy in LT recipients.
