Jd. Adachi et al., SALMON-CALCITONIN NASAL SPRAY IN THE PREVENTION OF CORTICOSTEROID-INDUCED OSTEOPOROSIS, British journal of rheumatology, 36(2), 1997, pp. 255-259
The objectives were to determine the efficacy and safety of nasal salm
on calcitonin 200 IU daily in the prevention of corticosteroid-induced
osteoporosis. A minimized, double-blind, placebo-controlled trial was
carried out in corticosteroid-treated patients with polymyalgia rheum
atica. The setting was a tertiary care university affiliated hospital
and a total of 31 patients were enrolled. The primary outcome measure
was the percentage change in bone mineral density of the lumbar spine
in the two treatment groups from baseline to 1 yr of follow-up. The me
an +/- S.D. bone mineral density of the lumbar spine in the calcitonin
-treated group decreased by 1.29 +/- 6.76% and in the placebo group by
4.95 +/- 3.50% after 12 months. The observed difference of 3.65 +/- 2
.10% between groups is statistically significant (P < 0.05). Nasal sal
mon calcitonin prevented loss of bone in the lumbar spine as measured
by dual-energy X-ray absorptiometry.
