Hypercalcemic and hypocalcemic disorders: diagnosis and treatment.
Current concepts concerning the mechanisms, diagnosis and means of treatment of a number of the major causes of hypercalcemia and hypocalcemia are reviewed. In particular, the role of abnormalities in metabolism of vitamin D including (1) excessive hepatic production of 25-hydroxyvitamin D (vitamin D intoxication), (2) increased production of 1 alpha, 25-dihydroxyvitamin D (hyperparathyroidism and sarcoidosis), (3) impaired production of 1 alpha, 25-dihydroxyvitamin D (hypoparathyroidism, renal failure, vitamin-D-dependent rickets type I, pseudohypoparathyroidism) and (4) resistance to 1 alpha, 25-dihydroxyvitamin D; the use of vitamin D and its metabolites therapeutically is discussed.
