Renal effects of calcitonin and parathyroid extract in man: Studies in hypoparathyroidism
AUTOR(ES)
Haas, Heinrich G.
RESUMO
To clarify the controversial renal action of calcitonin (CT) and a possible interrelationship between CT and parathyroid hormone, eight patients with untreated surgical hypoparathyroidism were studied. Various calcitonins, i.e. extracted porcine, synthetic porcine, synthetic human, and synthetic salmon CT in doses of 150 Medical Research Council U or 1.5 mg were infused over a 3 hr period. Subsequently, six of the same subjects received 500 USP U parathyroid extract (PTE) (Eli Lilly & Co., Indianapolis, Ind.) in 3 hr and later a combination of CT and PTE. In addition, two patients were given an infusion of ammonium phosphate with the aim of producting a phosphaturia of comparable degree as seen after CT and PTE, thus differentiating hormonal from nonhormonal influences on cation excretion. A protocol of serial clearance (C) studies using the patients as their own controls was followed. Serum and urinary inorganic phosphate (P), calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), and creatinine (Cr) were determined and the clearance values calculated.
