Prospective Clinical Trial Comparing Two Immunosuppressive Regimens, Tacrolimus and Mycophenolate Mofetil Versus Everolimus and Low-Dose Cyclosporine, in De Novo Renal Transplant Recipients: Results at 6 Months Follow-up
Objective: The aim of this study in renal transplant recipients was to compare a tacrolimus plus mycophenolate mofetil (MMF) immunosuppressive regimen with a combination of low dose of cyclosporine and everolimus. Patients and Methods: Sixty consecutive patients were prospectively assigned to receive tacrolimus and MMF (TAC; n = 30) or everolimus and low-dose cyclosporine (EVL; n = 30). Tacrolimus was dosed seeking a trough blood level of 8 to 10 ng/mL by month 3 and 5 to 8 ng/mL thereafter. Everolimus was dosed seeking a trough blood level of 3 to 8 ng/mL by day 7. Cyclosporine was dosed aiming at a C2 blood level of 350 to 700 ng/mL in the first week and 150 to 400 ng/mL thereafter. All patients received induction with basiliximab and maintenance treatment with corticosteroids. Results: At 6-months follow-up, patient survival rates (TAC 100% vs EVL 100%) and graft survival rates (TAC 96.7% vs EVL 93.3%) were not significantly different between the groups. Patients in the EVL group showed more acute rejection episodes, but serum creatinine concentrations and creatinine clearances were not significantly different from the TAC group. Among the observed side effects, hypercholesterolemia was significantly higher in the EVL group (total cholesterol: TAC 206 \ub1 38 vs EVL 250 \ub1 55 mg/dL; P < .003). Conclusions: This study showed that the immunosuppressive association of tacrolimus and MMF produced similar acute rejection episodes, graft survivals, and renal function at 6 months after renal transplantation compared with an immunosuppressive combination of everolimus and low-dose cyclosporine. Dyslipidemia was significantly greater among patients who received everolimus. \ua9 2009 Elsevier Inc. All rights reserved
Cardiovascular Risk Profile in Kidney Transplant Recipients Treated With Two Immunosuppressive Regimens: Tacrolimus and Mycophenolate Mofetil Versus Everolimus and Low-Dose Cyclosporine
Objective: The aim of this prospective study was to compare the cardiovascular risk (CVR) profile in patients treated with 2 different immunosuppressive regimens: tacrolimus and mycophenolate mofetil (TAC) compared with everolimus and low-dose cyclosporine (EVL). Patients and Methods: Sixty consecutive renal transplant recipients prospectively assigned to TAC (n = 30) or to EVL (n = 30) were followed for 6 months. TAC group immunosuppression consisted of basiliximab, tacrolimus, mycophenolate mofetil (MMF), and steroid. EVL group immunosuppression consisted of basiliximab, everolimus, and low doses of cyclosporine and steroid. Main CVR factors analyzed were: hypertension, dyslipidemia, posttransplant diabetes mellitus, and weight gain. Results: Six months posttransplantation, patients in the EVL group showed significantly higher mean serum cholesterol (P < .003) and serum triglyceride levels (P < .027), as well as a greater number of patients were receiving statin treatment (P < .05). Mean systolic blood pressure, mean diastolic blood pressure, number of patients treated for hypertension, number of antihypertensive medications prescribed per patient, posttransplant weight gain, and posttransplant diabetes mellitus were not significantly different among the EVL and TAC groups after 1, 3, and 6 months posttransplantation. Conclusions: This study showed that at 6 months posttransplantation, patients on EVL displayed significantly greater dyslipidemia with respect to the TAC group. A longer follow-up will be necessary to discover whether the presence of everolimus in the immunosuppressive regimen provides significant benefits for the CVR of renal transplant recipients. \ua9 2009
Increased cancer risk in patients undergoing dialysis: A population-based cohort study in North-Eastern Italy
Background: In southern Europe, the risk of cancer in patients with end-stage kidney disease receiving dialysis has not been well quantified. The aim of this study was to assess the overall pattern of risk for de novo malignancies (DNMs) among dialysis patients in the Friuli Venezia Giulia region, north-eastern Italy. Methods: A population-based cohort study among 3407 dialysis patients was conducted through a record linkage between local healthcare databases and the cancer registry (1998-2013). Person-years (PYs) were calculated from 30 days after the date of first dialysis to the date of DNM diagnosis, kidney transplant, death, last follow-up or December 31, 2013, whichever came first. The risk of DNM, as compared to the general population, was estimated using standardized incidence ratios (SIRs) and 95% confidence intervals (CIs). Results: During 10,798 PYs, 357 DNMs were diagnosed in 330 dialysis patients. A higher than expected risk of 1.3-fold was found for all DNMs combined (95% CI: 1.15-1.43). The risk was particularly high in younger dialysis patients (SIR = 1.88, 95% CI: 1.42-2.45 for age 40-59 years), and it decreased with age. Moreover, significantly increased DNM risks emerged during the first 3 years since dialysis initiation, especially within the first year (SIR = 8.52, 95% CI: 6.89-10.41). Elevated excess risks were observed for kidney (SIR = 3.18; 95% CI: 2.06-4.69), skin non-melanoma (SIR = 1.81, 95% CI: 1.46-2.22), oral cavity (SIR = 2.42, 95% CI: 1.36-4.00), and Kaposi's sarcoma (SIR = 10.29, 95% CI: 1.25-37.16). Conclusions: The elevated risk for DNM herein documented suggest the need to implement a targeted approach to cancer prevention and control in dialysis patients
Risk of de novo cancers after transplantation: results from a cohort of 7217 kidney transplant recipients, Italy 1997-2009
To assess incidence and risk factors for de novo cancers (DNCs) after kidney transplant (KT), we carried out a cohort investigation in 15 Italian KT centres. Seven thousand two-hundred seventeen KT recipients (64.2% men), transplanted between 1997 and 2007 and followed-up until 2009, represented the study group. Person years (PY) were computed from 30 days after transplant to cancer diagnosis, death, return to dialysis or to study closure. The number of observed DNCs was compared to that expected in the general population of Italy through standardised incidence ratios (SIR) and 95% confidence intervals (CI). To identify risk factors, incidence rate ratios (IRR) were computed. Three-hundred ninety five DNCs were diagnosed during 39.598PYs, with Kaposi's sarcoma (KS), post-transplant lymphoproliferative disorders (PTLD), particularly non-Hodgkin' lymphoma (NHL), lung, kidney and prostate as the most common types. The overall IR was 9.98/1.000PY, with a 1.7-fold augmented SIR (95% CI: 1.6-1.9). SIRs were particularly elevated for KS (135), lip (9.4), kidney carcinoma (4.9), NHL (4.5) and mesothelioma (4.2). KT recipients born in Southern Italy were at reduced risk of kidney cancer and solid tumors, though at a higher KS risk, than those born in Northern Italy. Use of mTOR inhibitors (mTORi) exerted, for all cancers combined, a 46% significantly reduced risk (95% CI: 0.4-0.7). Our study findings confirmed, in Italy, the increased risks for cancer following KT, and they also suggested a possible protective effect of mTORi in reducing the frequency of post transplant cancers
