[en] The calcium-sensing receptor (CaSR) has been implicated in the ischemia/ reperfusion (I/R) cascade in heart, liver and brain. Renal I/R occurs at the time of transplantation (Tx), with a deleterious impact on early graft function. Here, we retrospectively investigated if the use of cinacalcet, a CaSR agonist, in kidney transplant recipients (KTR) influences early graft recovery. All KTR from 2007 to 2012 in our Academic Hospital were prospectively included in a database. Patients actively treated with cinacalcet on the day of Tx were retrospectively identified from this database and matched with controls on (i) type of donor (living [LD], deceased after brain or circulatory death [DCD]); (ii) cold ischemic time (CIT) ` 1 h; (iii) residual diuresis (` 500 ml); and (iv) donor age (` 5 years). Delayed graft function (DGF) was defined as dialysis requirement after Tx. Baseline characteristics were compared between groups with student’s t-test or Chi-2 as appropriate. The endpoint was the percentage of DGF in both groups. Among 337 KTR, 36 (10.7%) were treated with cinacalcet at Tx. Control group included 61 patients. Characteristics of patients and donors are summarized in the table. DGF occurred in 42 and 23% of cinacalcet-treated and control groups, respectively (p = 0.05). These retro- spective observations suggest that CaSR activation at the time of Tx impairs early graft recovery.
