Abstract Background: HPLC is currently the preferred method for accurate measurement of mycophenolic acid (MPA). This study was designed to validate the Emit compared with HPLC in relation to clinical outcome measurements. Methods: Pediatric renal-transplant recipients (n = 50) on an immunosuppressive triple regimen consisting of cyclosporin A, prednisone, and mycophenolate mofetil (600 mg/m2 twice per day) were investigated in an open-label prospective study. Pharmacokinetic profiles over 12 h were obtained at 1 week, 3 weeks, 3 months, and 6 months posttransplant. Plasma MPA was measured by both reversed-phase HPLC and the Emit immunoassay. Results: There was an association between the risk of acute rejection episodes and low area under the curve values from t0 to t12h (AUC0–12) for MPA (MPA-AUC0–12) or predose concentrations of MPA derived from both HPLC and Emit measurements. According to ROC analysis, an AUC value of 33.8 mg · h/L for MPA from t0 to t12h (MPA-AUC0–12) determined by HPLC had a diagnostic sensitivity of 80% and a diagnostic specificity of 57%. The corresponding value of the Emit was 36.1 mg · h/L. For the predose concentration (MPA-c12), a concentration of 1.2 mg/L determined by HPLC and 1.4 mg/L determined by Emit gave a sensitivity of 80% and a specificity of 60%, respectively. There was no association of any pharmacokinetic variables derived from total MPA measurements with an increased risk of side effects related to mycophenolate mofetil. Conclusions: The Emit assay appears to have a comparable diagnostic efficacy to HPLC for assessing the risk of acute rejection in pediatric renal-transplant recipients. However, because of the cross-reactivity of the antibody used in the Emit assay with the active MPA acyl glucuronide metabolite, the decision thresholds for the Emit were higher than those calculated from HPLC measurements.

Abstract Background and Aims 2DR HLA mismatch indicates high immunological risk renal transplant. Induction therapy with rabbit Anti-thymocyte Globulin (r-ATG) and IL-2 Receptor Antagonist (IL-2RA) resulted in marked reduction of acute allograft rejection rate and improved graft survival. However, the outcomes in 2DR (HLA-DR) mismatched renal transplant recipients (RTRs) in the era tacrolimus-mycophenolate mofetil maintenance immunosuppression remains understudied. Method Using data from the United States organ procurement and transplantation network, all 2 DR mismatched RTRs with panel reactive antibodies <20% maintained on tacrolimus and mycophenolate mofetil immunotherapy between 2000 and 2017 were retrospectively reviewed. Data including age, sex, gender, ethnicity, functional status, diabetes, body mass index, cold ischemia time, number of previous transplants, panel reactive antibodies, donor type, donor age, HLA-mismatches, number of acute rejection episodes, induction therapies, maintenance immunotherapy, recipients and graft survival were collected. Based on induction therapies administered, RTRs were divided into 2 groups: (r-ATG) and IL-2RA groups. Poisson regression analysis was used to assess effect of induction therapies on acute rejection episodes. Cox hazard regression analysis was used to assess effect of different induction therapies on patient and graft survival Results 3379 patients received IL2-RA while 3677 patients received ATG for induction. There were no significant differences between both groups in terms of acute rejection episodes (95% CI ranges from 0.95 to 1.068, P=0.805), graft survival (95% CI: 0.91 - 1.06, P=0.712), or patient survival (95% CI: -0.949 - 1.12, P=0.43) . Conclusion This study revealed no significant difference in acute rejection episodes, patient or graft survival when utilizing ATG vs IL-2RA in 2DR HLA mismatched renal transplant recipients with PRA<20%, in the tacrolimus-based maintenance immunosuppression era. Therefore, IL2-RA is a safe induction therapy in this group of patients and non-inferior to –ATG induction therapy.
