This study was designed to evaluate whether paricalcitol was more effective than nutritional vitamin D for controlling SHPT in de novo kidney allograft recipients. This was a 6-month, investigator-initiated, multicenter, open-label, randomized clinical trial. Patients with pretransplantation iPTH between 250 and 600 pg/ml and calcium 110 pg/ml at 6 months. Secondary endpoints were bone mineral metabolism, renal function, and allograft protocol biopsies. The primary outcome occurred in 19.6% of patients in the PAR group and 36.2% of patients in the CAL group (P = 0.07). However, there was a higher percentage of patients with iPTH  Both PAR and CAL reduced iPTH, but PAR was associated with a higher proportion of patients with iPTH  YR 2017 FD 2017-09-28 LK https://hdl.handle.net/10668/25186 UL https://hdl.handle.net/10668/25186 LA en DS RISalud RD Apr 7, 2025
