  Purpose
Patients with a terminal chronic liver disease have a disordered bone metabolism resulting in a higher risk of falling ill with osteoporosis. Although liver transplantation restores liver function, immunosuppressive therapy (especially corticosteroids) after transplantation increases again the risk of osteoporosis and bone fragility. Zoledronate, a bisphosphonate, slows down the destruction of bone. The purpose of this study is to determine whether bisphosphonates are effective in the prevention of osteoporosis following immunosuppressive therapy after liver transplantation.

Primary Outcome Measures:
  • first bone fracture or death within 24 months after liver transplantation

Secondary Outcome Measures:

  • serum biochemical bone markers (osteocalcin, alkaline phosphatase, parathyroid hormone)
  • histomorphometric measurements of transiliacal bone biopsies (intraoperative, 6 months post-transplant)

Estimated Enrollment: 96
Study Start Date: April 2002
