Evaluation of the Relationship Between Concentrations of Tacrolimus Metabolites, 13-O-Demethyl Tacrolimus and 15-O-Demethyl Tacrolimus, and Clinical and Biochemical Parameters in Kidney Transplant Recipients

Our data may reflect 13-DMT accumulation in liver dysfunction and higher Tac clearance in anemia. However, these results may suggest that 13-DMT/Tac ratio is a marker of myelotoxicity and hepatotoxicity. Further studies should be carried out to determine whether monitoring of 13-DMT could be beneficial in minimizing the adverse effects.
