Background
Etelcalcetide is the first intravenous calcimimetic authorized for the treatment of SHPT in haemodialysis (HD). It has proven to be effective in lowering parathyroid hormone (PTH), with an acceptable and comparable safety profile. There have only been a few reports regarding treatment of SHPT using etelcalcetide in clinical practice.
Methods
The aim of this deriptive study was to evaluate the results of using etelcalcetide in patients on HD with SHPT.
Results
Thirty patients on HD received etelcalcetide were enrolled (figure 1). The minimum observation period was 6 months. Fifteen (50%) were previously with cinacalcet (group 1) and 15 (50%) received etelcalcetide at onset (group 2). In global, serum PTH levels were significantly decreased at the end of follow up compared to baseline levels ( PTH pretreatment 784 +/- 707 (p 0.0077) vs PTH end of follow- up
671 +/- 680 (p 0.0077) ). When comparing both groups, we found a significant decrease of Ca, P and PTH in group 2. However, we only found significant decrease of Ca in group 1 (figure 2). The dosage of calcium binders (33.3% pretreatment vs 56.7% at the end of follow-up, p 0.054), non-calcium binders (40% pretreatment vs 63.3% at the end of follow-up, p 0.02) and vitamin D analogues (56,7% pretreatment vs 66,7% at the end of follow-up, p 0,3) were increased when etelcalcetide treatment was started. No changes were made in dialysate calcium concentration. Six patients, presented hypocalcemia (Ca < 7.5 mEq/l)
Conclusion
In our cohort, etelcalcetide has shown to be effective in reducing serum PTH. An increase in the use of vitamin D analogues, calcium binders and non-calcium binders has been observed, probably due to the hypocalcemia.
