Treatment using direct-acting antivirals provides high rates of sustained virologic response and a favorable safety profile for patients with chronic hepatitis C virus infection. However, data on the efficacy of direct-acting antivirals in kidney transplant recipients are still limited.
To evaluate the safety and efficacy of fixed-dose sofosbuvir/ledipasvir combination in kidney transplant recipients.
Retrospective, observational, single-center study.
Data of 29 kidney transplant recipients who received a fixed-dose safety and efficacy of fixed-dose sofosbuvir/ledipasvir combination for 12 or 24 weeks with or without ribavirin were analyzed. The primary outcome was SVR12, which was defined as undetectable HCV-RNA levels 12 weeks after the treatment. Secondary outcomes were graft function, proteinuria, and calcineurin inhibitor trough level variability.
The predominant hepatitis C virus genotype was 1b (n = 19, 65.6%). All patients achieved SVR12. No graft failures nor deaths were reported during the study period. Throughout and after the treatment, the levels of aspartate aminotransferase [21 (range: 18-29.5) to 16 (range: 14-20) U/l, < 0.001] and alanine aminotransferase [22 (range: 15-34) to 14 (range: 12-17.5) U/l, < 0.001] improved significantly, unlike bilirubin, hemoglobin, and platelet levels. Renal function remained stable. Dose adjustments for calcineurin inhibitors were required. Serious adverse events were not observed.
Safety and efficacy of fixed-dose sofosbuvir/ledipasvir combination was effective and safe in kidney transplant recipients with hepatitis C virus. However, cautious monitoring of trough levels of calcineurin inhibitorss is needed due to potential drug-drug interactions during the treatment episode.
