Background: The path of success of kidney transplantation reflects the accuracy of immunological risk assessment and the choice of the correct induction and maintenance immunosuppression to avoid acute kidney rejection.

Methods: We performed multicentre prospective analysis consisting of patients after kidney transplantation with 12-month follow-up. The aim of the study was to stratify the immunological risk based on the presence of risk factors using different induction immunosuppressive protocols.

Results: 152 kidney transplant recipients were included, 100 males (66.4 %). We divided patients according to induction immunosuppression: no induction (n = 19), induction with basiliximab (n = 60), induction with ATG cumulative does 3.5 mg/kg (n = 42) and 6 mg/kg (n = 31). In our study, we demonstrated a shorter survival of patients without induction immunosuppression. In basiliximab group duration of dialysis ≥ 3 years (P = 0.0191), cold ischaemia time ≥ 1020 minutes or expected delayed graft function (P < 0.0001) are independent risk factors for graft loss (P = 0.0097).

Conclusions: Risk of no induction immunosuppression significantly exceeds the risks associated with its administration and is desirable even in patients with low immunological risk. Induction immunosuppression should be tailored individually from patient to patient.
