Sustained biochemical effects of short treatment of Paget's disease of bone with dichloromethylene diphosphonate. 1983

M C Chapuy, and S A Charhon, and P J Meunier

The relationship between duration of treatment and biochemical parameters reflecting antiosteoclastic activity was studied in 26 patients with Paget's disease of bone receiving Cl2MDP 1600 mg/day. Six months after initiation of therapy, the reduction in total urinary hydroxyproline was not different in patients treated for 1, 3, 5, or 6 months. This remission lasted 1 year for all groups. In contrast, the longest treatment induced the greatest reduction in serum alkaline phosphatase. One year after the initiation of therapy, this reduction was sustained, whereas a slight relapse was noted in other groups. From these findings, it appears that a rapid bone load with oral Cl2MDP can induce a long-lasting reduction in bone resorption excess.

D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
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.

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.
