Aims: The pan-European ECHO observational study evaluated cinacalcet in adult dialysis patients with secondary hyperparathyroidism (SHPT) in "real-world" clinical practice. A sub-analysis compared data for 7 European countries/country clusters: Austria, CEE (Czech Republic and Slovakia), France, Italy, Netherlands, Nordics (Denmark, Finland, Norway, and Sweden), and the UK/Ireland.
Methods: Data on serum intact parathyroid hormone (iPTH), phosphorous, calcium, as well as the usage of cinacalcet, active vitamin D analogues and phosphate binders were compared.
Results: 1,865 patients (mean age 58 years) were enrolled: median baseline iPTH levels ranged from 605 pg/ml in Austria to 954 pg/ml in the UK/Ireland. After ~1 year of cinacalcet, median iPTH reductions from baseline ranged from 38% in the UK/Ireland to 58% in the Netherlands. The proportion of patients achieving NKF/K-DOQITM iPTH targets (150 - 300 pg/ml) at Month 12 ranged from 14% in the UK/Ireland to 40% in CEE. In general, use of sevelamer decreased, while use of calcium-based phosphate binders increased, during cinacalcet treatment. Vitamin D changes were more variable.
Conclusion: The iPTH level at which cinacalcet is initiated in clinical practice differs considerably among different countries: where cinacalcet was started at a lower iPTH level this resulted in better achievement of serum iPTH targets.
