Background Tenofovir disoproxil fumarate (TDF) is frequently used for treatment of and prophylaxis against reactivation of hepatitis B virus (HBV) after liver transplant (LT). Because TDF can lead to renal impairment and a decrease in bone mineral density (BMD), the prodrug tenofovir alafenamide (TAF) may be considered a viable alternative with fewer adverse effects. Only limited information is available about the use of TAF for LT recipients. We report a European single‐center experience with TAF as treatment for LT patients. Methods This retrospective analysis involved 29 LT recipients receiving standard immunosuppressants (mainly calcineurin inhibitors). Demographic and clinical data were documented at baseline upon switch to TAF and at various time points thereafter. Results None of the patients experienced HBV reactivation after the switch to TAF. Liver and renal function remained stable. Drug levels of immunosuppressive agents did not change significantly after the switch. After 1 year, 22 patients were still taking TAF; two patients had been lost to follow‐up; one patient had died; and four patients had discontinued therapy because of TAF‐related adverse effects. No serious adverse effects were reported. Conclusions Tenofovir alafenamide exhibits high antiviral efficacy and a good safety profile for LT recipients. Still, the safety and tolerability of TAF for organ transplant patients should be evaluated in larger cohorts.
