Early Calculation of the Tacrolimus Concentration-to-Dose Ratio Does Not Predict Outcomes after Renal Transplantation
K. Schütte-Nütgen, I. Bartmann, B. Suwelack, S. Reuter
Department of Internal Medicine D, University Hospital Münster, Münster, Germany
*Purpose: There is emerging interest in the concentration-to-dose (C/D) ratio of tacrolimus (Tac) as it is linked to outcomes after renal transplantation (RTx). Recently, we…

Protective Effect of Fucoidan Against Tacrolimus-Induced Nephrotoxicity in LLC-PK1 Cells
H. J. Jang
Surgery, University of Ulsan, Gangneung Asan Hospital, Gangneung, Korea, Republic of
*Purpose: Tacrolimus (FK506) is an immunosuppressant agent that is frequently used to prevent rejection of solid organs upon transplant. However, nephrotoxicity due to apoptosis and…
