Formation of antibodies to synthetic human calcitonin during treatment of Paget's disease. 1979

F M Dietrich, and J A Fischer, and O L Bijvoet

Low-titre antibodies to synthetic human calcitonin (hCT) were detected in a 69-year-old woman suffering from Paget's disease who was treated for 16 months with hCT and the diphosphonate EHDP. Levels of antibody were highest between 10 and 18 months after commencement of therapy, slowly decreased after completion of treatment and were later no longer measurable. There was no immunological response to a single re-injection of hCT 14 months after discontinuation of therapy. Formation of antibodies to hCT in man is a very rare event, this being the first recorded case of an immune response to synthetic human calcitonin, whereas synthetic salmon calcitonin induces an immune response in a high percentage (up to 78%) of the patients treated with this hormone.

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.

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.

D004164	Diphosphonates	Organic compounds which contain P-C-P bonds, where P stands for phosphonates or phosphonic acids. These compounds affect calcium metabolism. They inhibit ectopic calcification and slow down bone resorption and bone turnover. Technetium complexes of diphosphonates have been used successfully as bone scanning agents.

D000906	Antibodies	Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).
