Abstract/OtherAbstract:
Abstract Rationale/objectives: Data are limited regarding the use of paricalcitol in calcitriol-resistant patients with secondary hyperparathyroidism (SHPT). We aimed to evaluate the effects of paricalcitol in calcitriol-resistant hemodialysis patients with SHPT. Methods: This is a 12-month, open-label, prospective study. Forty patients with calcitriol-resistant and/or calcitriol-intolerant SHPT were included. After a washout period, all patients converted to paricalcitol with a 1:3 conversion ratio. Serum calcium and phosphorus were monitored monthly, while serum intact parathyroid hormone (iPTH) once in every 3 months. Paricalcitol dose was reduced or discontinued in case of hypercalcemia and/or hyperphosphatemia. Pre- and posttreatment electrolyte and iPTH values were compared with Student's t-test and Wilcoxon signed-rank test, respectively. Main findings: Forty patients completed the study. Mean initiation dose of paricalcitol was 23 ± 7 μg/week. Mean serum calcium was 8.9 ± 0.8 mg/dL at baseline and 9.4 ± 0.7 mg/dL at study end (p = 0.07). Mean monthly serum phosphorus levels stayed stable. Paricalcitol was effective in reducing iPTH levels when compared with pretreatment values (747.9 ± 497.2 pg/mL, 307.3 ± 417.1 pg/mL, respectively; p < 0.001). Thirty-two patients had to discontinue intravenous (IV) paricalcitol at some time during their treatment. Main reasons for discontinuation were as follows: hyperphosphatemia (58%), hypercalcemia (25%), and iPTH < 150 pg/mL (17%). Principle conclusions: Paricalcitol was found to be effective in reducing iPTH levels in calcitriol-resistant patients with SHPT despite relatively frequent drug discontinuation rates.
