Treatment of Paget's disease of bone with porcine calcitonin: clinical and metabolic responses. 1975

J A Kanis, and K Fitzpatrick, and J A Strong

The clinical and metabolic responses of 12 patients with painful Paget's disease have been assessed before, during and after an 18-day course of treatment with purified porcine calcitonin, 160 MRC units i.m. daily. The indices of response included relief from pain, changes in concentration of serum alkaline phosphatase, calcium, magnesium, electrolytes and plasma inorganic phosphate; balance studies of calcium, phosphate, magnesium and in some cases sodium and potassium were undertaken. Urinary excretion of hydroxyproline was also measured. Remission of pain was complete in 11 of 15 courses of treatment. Coexistent osteoarthrosis was considered to be responsible where remission was incomplete. The mean duration of remission of pain was 12 months. Three patients who received a second course of treatment achieved further remission of pain. Side effects were not troublesome. Serum levels of alkaline phosphatase decreased to 67 per cent of the initial reading and the degree of suppression depended on the initial alkaline phosphatase activity. Urinary hydroxyproline correlated closely with the activity of serum alkaline phosphatase before, during and after treatment. The ratio of serum alkaline phosphatase:hydroxyproline excretion rose at the start and at the termination of treatment. Retention of calcium and inorganic phosphate occurred during the early phase of treatment only. Withdrawal of treatment resulted in a rebound retention of calcium and inorganic phosphate. The degree of calcium retention after treatment correlated with the level of plasma inorganic phosphate prevailing before treatment. The efficacy of these short courses of calcitonin are discussed and the metabolic observations related to theories of bone remodelling at a cellular and hormonal level.

UI	MeSH Term	Description	Entries
D008274	Magnesium	A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009584	Nitrogen	An element with the atomic symbol N, atomic number 7, and atomic weight [14.00643; 14.00728]. Nitrogen exists as a diatomic gas and makes up about 78% of the earth's atmosphere by volume. It is a constituent of proteins and nucleic acids and found in all living cells.
D010001	Osteitis Deformans	A disease marked by repeated episodes of increased bone resorption followed by excessive attempts at repair, resulting in weakened, deformed bones of increased mass. The resultant architecture of the bone assumes a mosaic pattern in which the fibers take on a haphazard pattern instead of the normal parallel symmetry.

D010281	Parathyroid Hormone	A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.

D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D001861	Bone Regeneration	Renewal or repair of lost bone tissue. It excludes BONY CALLUS formed after BONE FRACTURES but not yet replaced by hard bone.	Osteoconduction,Bone Regenerations,Regeneration, Bone,Regenerations, Bone
D002116	Calcitonin	A peptide hormone that lowers calcium concentration in the blood. In humans, it is released by thyroid cells and acts to decrease the formation and absorptive activity of osteoclasts. Its role in regulating plasma calcium is much greater in children and in certain diseases than in normal adults.
