Conditions osteoporosis, liver transplantation
Treatment zoledronate
Sponsor Medical University of Vienna
Start date April 2002
Trial size 96 participants
Trial identifier NCT00302484, LTX-BISPHO-01


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.
