Abstract :
[en] Thirty pagetic patients were treated for 6 months with a daily nasal application of 2 mg of synthetic human calcitonin (hCT). Serum alkaline phosphatases (SAP) and urinary hydroxyproline/creatinine ratio (OH/Cr), reflecting bone turnover, were significantly reduced from the first month of treatment (mean +/- SEM: SAP, -13.9 +/- 2.2%; OH/Cr, -22.2 +/- 5.8%; both P less than 0.01) and until the end of the 6-month course (mean +/- SEM: SAP, -29.7 +/- 4.6%; OH/Cr, -22.5 +/- 5.9%; both P less than 0.01). Nasal hCT was perfectly tolerated both locally and systemically. These results allow us to consider nasal hCT for long-term trials in metabolic bone diseases characterized by a relative increase of bone resorption.
