Long-term treatment of Paget's disease of bone with salmon calcitonin.
|
| Abstract |
Twenty-eight patients with symptomatic Paget's disease of bone were treated with synthetic salmon calcitonin for periods of 9 to 42 months (average, 23 months). Serum alkaline phosphatase concentration and urinary hydroxyproline excretion, which had been elevated before treatment, were decreased by calcitonin treatment in all patients, and some decrease was sustained in 23 in association with variable decreases in pain, heat and stiffness of major joints. Improvement was sustained further in approximately half of these patients; the other half had partial return of symptoms. Calcium absorption was increased in 9 of 10 patients studied; the increase did not correlate with plasma concentrations of parathyroid hormone. The mean endogenous fecal calcium excretion was decreased significantly but there was no significant change in mean urinary calcium excretion. Mean accretion rate of calcium to bone, studied in 10 patients, was decreased by 35% after 6 months of treatment and by a further 23% 1 year later. There was no consistent effect of calcitonin treatment on bone mineral mass. No serious adverse effects of treatment such as allergic reactions were observed. Calcitonin appears to be effective initially in most patients with Paget's disease of bone, but with long-term treatment resistance may be acquired.
