Summary

Loss of bone mass is a common complication in patients with end-stage-renal failure, both before and particularly after transplantation. In addition to standard underlying therapy with calcium and active vitamin D, we will study the effect of ibandronate (a bisphosphonate) versus placebo on bone mineral density as well as incidence of fracture rates after kidney transplantation.We also wish to study whether any prevented bone loss will also lead to reduced cardiovascular disease. Patients will be followed for 12 months after transplantation, and the ibandronate treatment is one injection every 3 months.

Detailed description

Demographic, medical history, previous and current medication, as well as baseline measurements of Bone Mineral Density (BMD), laboratory efficacy and safety variables as well as Quality-of-Life scores will be undertaken in the period from 1 week prior to transplantation until 1 week after transplantation. In this period, any existing fractures will be determined using traditional x-ray of the thoraco-lumbar columna. Renal graft functioning as well as transplantation complications will be followed tightly, and calcium supplementation as well as active vitamin D (calcitriol) will be administered together with the standard immunosuppressive regimen. As soon as patients have recovered from transplantation, and renal functioning is considered sufficiently stable, and no later than 28 days after the transplantation, qualified patients will be randomised to receive either ibandronate or placebo, stratified by gender. Bone mineral density and most of the clinical data and laboratory tests will then be followed until 12 months after transplantation as described in the attached flowchart (section 11.1), with hospital visits for administration of study drugs and follow-up of at 13, 26, 39 and 52 weeks after transplantation. Furthermore, all the patients will be followed prospectively from the time of transplantation and for ten years with regard to cardiovascular events. Data concerning cardiovascular events will be collected from the Norwegian renal registry for the whole study population in the follow up period of about 10 years.
