Abstract
Background. This prospective, randomized, controlled trial compared the progression of vascular and cardiac valve calcification in 360 prevalent adult hemodialysis patients with secondary hyperparathyroidism treated with either cinacalcet plus low-dose vitamin D sterols or flexible doses of vitamin D sterols alone.
Methods. Eligible subjects were on hemodialysis for ≥ 3 months with parathyroid hormone (PTH) > 300 pg/mL or PTH 150–300 pg/mL with calcium–phosphorus product > 50 mg2/dL2 while receiving vitamin D. All subjects received calcium-based phosphate binders. Coronary artery calcification (CAC) and aorta and cardiac valve calcium scores were determined both by Agatston and volume scoring using multi-detector computed tomography. Subjects with Agatston CAC scores ≥ 30 were randomized to cinacalcet (30–180 mg/day) plus low-dose calcitriol or vitamin D analog (≤ 2 μg paricalcitol equivalent/dialysis), or flexible vitamin D therapy. The primary end point was percentage change in Agatston CAC score from baseline to Week 52.
Results. Median (P10, P90) Agatston CAC scores increased 24% (− 22%, 119%) in the cinacalcet group and 31% (− 9%, 179%) in the flexible vitamin D group (P = 0.073). Corresponding changes in volume CAC scores were 22% (− 12%, 105%) and 30% (− 6%, 133%; P = 0.009). Increases in calcification scores were consistently less in the aorta, aortic valve and mitral valve among subjects treated with cinacalcet plus low-dose vitamin D sterols, and the differences between groups were significant at the aortic valve.
Conclusions. In hemodialysis patients with moderate to severe secondary hyperparathyroidism, cinacalcet plus low-dose vitamin D sterols may attenuate vascular and cardiac valve calcification.
