The aim of this study is to characterize and evaluate risk factors of polyomavirus nephropathy (PVN) including the impact of three immunosuppressive regimens.
Polyomavirus nephropathy (PVN) is an emerging cause of renal transplant loss. Until now the risk factors of PVN are poorly understood. Tacrolimus (Tacr) and mycophenolate mofetil (MMF) are thought to be associated with a higher risk of developing PVN. However, the way in which Tacr or MMF might enhance the susceptibility for PVN remains largely unknown. In this prospective study we will analyze whether differences in immune-reactivity patterns (Th1, Th2, B cell and monocyte responses, sCD30, immunoregulatory antibodies) of renal transplant patients induced by different immunosuppressive regimens (cyclosporine A [CsA]/MMF, Tacr/MMF, Tacr/MMF with conversion to Tacr/Everolimus [ERL]) or by cytokine promoter gene polymorphisms may account for the different risks of developing PVN.
Comparison(s): renal transplant recipients stratified according to their relative immunological risk (group 1: low risk (primary recipients without pre-immunization [PRA < 5%]); group 2: moderate risk (group 2a: primary recipients with low pre-immunization [PRA 6-20%]; group 2b: re-transplanted patients); group 3: very high risk (re-transplanted patients with a history of vascular rejection or recipients of a first graft with high pre-immunization [PRA > 20%]) randomized to be treated with one of three immunosuppressive regimens (CsA/MMF, Tacr/MMF, Tacr/MMF with subsequent conversion to Tacr/ERL).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 1 | Active Comparator | Immunosuppression with Ciclosporin and Mycophenolate-mofetil; Ciclosporin treatment being started at the latest at day 4 after transplantation with 7 mg/kg body weight daily administered every 8 hours until the target trough level of 300 µg/l was reached. Then it was administered twice daily with daily monitoring of trough levels. The target trough level was lowered to 200 µg/l 1 month after transplantation. Thereafter dosage and target trough levels were adjusted at the investigators discretion. Mycophenolate-mofetil was started previous to transplantation procedure with a starting dosage of 3 g/day administered twice daily. Once ciclosporin was entered into the therapy-scheme Mycophenolate-mofetil dosage was reduced to 2 g/daily. The therapy was controlled by measuring of trough levels with a target trough level exceeding 1 µg/ml. The dosage was adjusted at the investigators discretion. |
|
| 2 | Active Comparator | Immunosuppression with Tacrolimus and Mycophenolate-mofetil Mycophenolate-mofetil was started previous to transplantation procedure with a starting dosage of 3 g/day administered twice daily. Once tacrolimus was entered into the therapy-scheme Mycophenolate-mofetil dosage was reduced to 2 g/daily. The therapy was controlled by measuring of trough levels with a target trough level exceeding 1 µg/ml. The dosage was adjusted to clinical signs of overimmunosuppression (infections) or intolerance (mainly gastrointestinal side effects) or rejections. |

| 3 | Active Comparator | Immunosuppression with Tacrolimus and Mycophenolate-mofetil with change from Mycophenolate-mofetil to Everolimus after completion of posttransplant wound healing |
