Brief summary

The evaluation of efficacy is performed by laboratory monitoring of bone density and resorption markers and clinical monitoring of bone density improvement. This is a prospective, randomized, parallel group, single blind study of one year treatment with zoledronic acid every 6 months as compared to one year treatment with zoledronic acid every 3 months and to placebo every 3 months in patients with hemoglobin syndromes and risk of skeletal complications.

Design outcomes

Primary

MeasureTime frame
Bone density by means of bone densitometry with dual energy x-ray absorptiometry (DEXA) at three body sites (lumbar region, femoral head, wrist) prior to treatment initiation the start and at the end of treatment
N-telopeptide of type I collagen (NTx) levels, TRACP-5b, with ELISA, prior to the start of treatment initiation and every 3 or 6 months
Serum Bone alkaline phosphatase, Osteocalcin, OPG and S-RANKL with ELISA, prior to the start of treatment initiation, and every 3 or 6 months

Secondary

MeasureTime frame
Biochemistry (Ca, P, urea/creatinine, SGOT/SGPT, ALT, γGT), endocrine and cardiac test prior to the start of treatment initiation and at 6 and 12 month.
