Study type | Interventional |
Organ transplant recipients are known to suffer from bone loss and subsequent fractures after the transplant operation with the most rapid bone loss occurring within the first 3-12 months. Guidelines for prevention and treatment of this serious complication are only written by individual medical societies interested in each organ (separate kidney from liver or heart transplants management) and they are based on studies done with limited medications choices. The majority of studies are done with the use of bisphosphonates, and there are very limited, or no data, on the effect of other medications used for Osteoporosis, including the use of denosumab. This study will focus on the evaluation of the efficacy and safety of denosumab 60mg use early (within first 3 months) after Liver Transplantation in the management of bone loss and prevention of fragility fractures. Different tests will be used to study the effect of the medication on the skeleton, including imaging studies as well as specific labwork.
