Predictors of Rejection in Pediatric Kidney Transplantation

The most common medication regimen in the United States includes the combination of corticosteroid (eg, prednisone), a calcineurin inhibitor (or CNI, most commonly tacrolimus), and an antimetabolite such as mycophenolate mofetil (MMF). Cyclosporine and azathioprine are less commonly used for maintenance immunosuppression Tacrolimus level is a main maintenance immunosuppressant in kidney transplantation .In the early days of posttransplant period, hematocrit concentrations are generally low and increase significantly as patient recovers. Because tacrolimus binds strongly to erythrocytes in systemic circulation, the effect of hematocrit on distribution of tacrolimus is important for the methods used to measure tacrolimus concentrations ,hematocrit correction could be a step towards improvement of tacrolimus dose individualization Thearputic drug monitoring of MPA has been proposed to optimize drug dosage avoiding potential hematologic and digestive side effects .MPA monitoring is generally based on the determination of the plasma MPA trough concentration (C0) .
