Paricalcitol vs. cinacalcet for secondary hyperparathyroidism in chronic kidney disease: A meta-analysis
Paricalcitol and cinacalcet have been recommended to reduce parathyroid hormone (PTH) levels for patients with secondary hyperparathyroidism (SHPT) and chronic kidney disease (CKD), and they are able to reduce the risk of hypercalcemia and hyperphosphatemia. However, to date, it has remained uncertain which is the better drug. The aim of the present meta-analysis was to evaluate the effects on PTH, calcium and phosphorus metabolism between the two drugs. The PubMed, the Cochrane Library and Embase databases were searched from inception to June 1, 2019 and eligible studies comparing paricalcitol and cinacalcet for SHPT were included. Data were analysed using Review Manager version 5.3. A total of 7 trials from six articles, comprising 456 patients in the paricalcitol group and 412 patients in the cinacalcet group, were included in the meta-analysis. There were no differences in PTH levels [mean difference (MD): 71.82, 95% CI: -185.20-328.85, P=0.58] and phosphorus levels (standard MD: 0.59, 95% CI: -0.82-2.00, P=0.41). The calcium levels in the paricalcitol group were significantly higher than those in the cinacalcet group (MD: 1.10, 95% CI: 0.92-1.28, P<0.05). In conclusion, paricalcitol and cinacalcet exhibited no difference in their efficacy to control of PTH levels, as they were similarly effective in decreasing the PTH levels. They also had comparable efficacy in the management of phosphorus levels. However, cinacalcet produced a significantly greater reduction in serum calcium levels. More large multicentre randomized controlled trials are necessary to confirm the conclusions of the present analysis.
