Secondary hyperparathyroidism is a common complication of chronic kidney disease. The elevated serum intact parathyroid hormone, phosphorus, calcium and calcium x phosphorus product have been independently associated with an increased relative risk of mortality. The standard therapy for secondary hyperparathyroidism, including active vitamin D analogues and phosphate binders, is often insufficient to allow patients to achieve the recommended Kidney Disease Outcomes Quality Initiative targets for bone and mineral metabolism. Randomised controlled phase III clinical studies in chronic kidney disease patients with secondary hyperparathyroidism have shown that cinacalcet treatment increases the proportion of patients achieving the recommended Kidney Disease Outcomes Quality Initiative targets for intact parathyroid hormone, phosphorus, calcium and calcium x phosphorus product. Aims: This observational multicentre study aims to evaluate cinacalcet’s ability to achieve and maintain Kidney Disease Outcomes Quality Initiative targets in a population with secondary hyperparathyroidism on chronic haemodialysis in Portugal.
