Medical management of secondary hyperparathyroidism in chronic renal failure

Nephrol Dial Transplant. 2003 Jun:18 Suppl 3:iii2-8. doi: 10.1093/ndt/gfg1002.


Abnormalities in calcium and phosphorus metabolism are common, and metabolic bone disease develops often in patients with chronic renal failure (CRF). Effective clinical management includes measures to control phosphorus retention and prevent hyperphosphataemia, to maintain serum calcium concentrations within the normal range and to prevent excess parathyroid hormone (PTH) secretion by the judicious use of vitamin D sterols. Certain of these interventions appear to increase the risk of soft tissue and vascular calcification in patients with end-stage renal disease (ESRD), changes that may contribute to the development of cardiovascular disease. Current therapeutic approaches are thus being re-evaluated in an effort to limit these risks. Despite the importance of controlling phosphorus retention and preventing hyperphosphataemia in patients with CRF, current management strategies often are inadequate, particularly in those ingesting diets containing adequate amounts of protein. Results from clinical trials using daily haemodialysis strongly suggest that thrice-weekly haemodialysis regimens are only marginally adequate for achieving weekly phosphorus balance in many patients with ESRD. The safety of large oral doses of calcium as a phosphate-binding agent in patients with ESRD has also been questioned because excess amounts of calcium that are absorbed from the gastrointestinal tract may lead to ongoing calcium retention in those with little or no residual renal function. Arterial calcification and cardiac valve calcification are two serious complications that adversely affect cardiovascular haemodynamics. The use of large, often supraphysiological, doses of calcitriol or other vitamin D sterols to treat secondary hyperparathyroidism may aggravate hypercalcaemia and hyperphosphataemia, further increasing the risk of soft tissue and vascular calcification. Phosphate-binding agents that do not contain calcium, new vitamin D analogues and calcimimetic compounds offer new therapeutic alternatives for managing renal osteodystrophy. The integration of these novel agents into existing treatment regimens may provide safer and more effective methods for controlling secondary hyperparathyroidism and renal bone disease, while limiting the risks of soft tissue and vascular calcification in patients with CRF.
