Primary hyperparathyroidism and renal osteodystrophy

Abstract

Primary hyperparathyroidism is a common condition infrequently complicated by renal stones and overt bone disease. Most cases are asymptomatic or have vague, nonspecific symptoms. There is considerable debate as to whether mild or asymptomatic cases should be managed surgically or conservatively. Important chromosomal abnormalities have now been demonstrated in some parathyroid adenomas. Renal osteodystrophy remains a difficult condition to treat once it is fully established. The use of vitamin D metabolites in the early stages of renal failure and the maintenance of a normal serum calcium and phosphate appear to prevent the development of secondary hyperparathyroidism. Further studies are required to ascertain the optimum way of using vitamin D metabolites and how best to reduce serum phosphorus.
