Although administration of tacrolimus, whether by the enteric, sublingual, or continuous intravenous routes, has some limitations, twice-daily bolus intravenous tacrolimus administration has been shown to be beneficial in optimizing efficacy and safety after lung transplantation. However, at present, the duration of bolus intravenous tacrolimus administration is limited, and the effects of prolonged bolus intravenous tacrolimus administration remain unknown. Our study was aimed at assessing the safety and efficacy of prolonged twice-daily bolus intravenous tacrolimus administration in the early phase after lung transplantation.
MATERIAL AND METHODS: We retrospectively investigated the data of 62 recipients of lung transplantation who had received twice-daily bolus intravenous administration of tacrolimus, followed by oral tacrolimus, after lung transplantation at our institution between January 2011 and October 2015.
RESULTS: The median duration of bolus intravenous tacrolimus administration was 19 days (4–72 days). The target trough level was achieved in 89% of the patients by day 3. Acute kidney injury occurred in 27% of the patients during bolus intravenous tacrolimus. Two patients (3%) had neurotoxicity, necessitating discontinuation of tacrolimus. Suspected acute rejection requiring steroid pulse therapy occurred in 21% of patients during the follow-up period. Eight patients (13%) developed chronic lung allograft dysfunction during the follow-up period. The 1-year and 5-year survival rates after lung transplantation were 95% and 76%, respectively.
CONCLUSIONS: These results suggest that prolonged bolus intravenous tacrolimus administration in the early phase after lung transplantation is a safe and effective alternative to enteric, sublingual, or continuous intravenous administration.
