About this trial

This is an interventional prevention trial for Metabolic Bone Disease focused on measuring transplant related disorders, liver transplant, transplant related bone disease

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion criteria

  • First time liver transplant candidates deemed too early for liver transplant
  • 24 hour urine Creatinine clearance of > 40 mg/dl. However bone turnover markers (beta CTx and P1NP) will be measured only in those with creatinine clearance >60mg/dl

Exclusion criteria

  • Patients with prior solid organ transplantation
  • Liver/kidney combination will be excluded
  • Patients with 24 hr. urine creatinine clearance < 40mL/minute
  • Patients who have been on osteoporosis medications - Bisphosphonates [Fosamax (Alendronate), Actonel (Risedronate), Boniva (Ibandronate), or Reclast (Zoledronic acid)] Teriparatide (Forteo), Abaloparatide (Tymlos), Denosumab (Prolia), within the past 5 years
  • Use of other systemic medications that can effect bone remodeling including sex hormone replacement therapy (estrogen or testosterone), calcitonin, androgen deprivation therapy, aromatase inhibitors, or SERMS in the past 6 months
  • Underlying disease that significantly impacts bone metabolism such as primary hyperparathyroidism, hyperthyroidism, Paget's disease of bone, fibrous dysplasia, or malignancies with skeletal metastases

Sites / Locations

  • Mayo Clinic in Florida

Arms of the Study

Arm 1

Arm Type

Arm Label

Vertebral fracture assessment

Arm Description

Study participants undergoing evaluation for liver transplant and deemed to early for transplant will receive standard of care bone mineral density and vertebral fracture assessment..

Outcomes

Primary Outcome Measures

Incident of clinical fractures validated by spine x-ray or other imaging (vertebral fracture assessment -VFA)
Proportion of participants experiencing a clinical fracture validated by x-ray or other imaging (VFA) as compared to standard of care ( Spine X-ray)

Secondary Outcome Measures

Changes in bone mineral density by dual x-ray absorptiometry
Bone mineral density changes seen in end stage liver disease in (grams/cm2) at baseline and 12 months
Percent changes from baseline to 12 months estimation of bone strength derived from finite element analysis
Bone strength measurements derived from finite element assessment changes from baseline to 12 months and correlation with clinical and radiographic risk of fracture
Changes in bone turnover markers in end stage liver disease
Bone turnover markers (Beta CTX, P1NP) percent changes from baseline to 12 months

8. Arms, Groups, and Interventions

Arm Title
Vertebral fracture assessment
Arm Type
Other
Arm Description
Study participants undergoing evaluation for liver transplant and deemed to early for transplant will receive standard of care bone mineral density and vertebral fracture assessment..
Intervention Type
Diagnostic Test
Intervention Name(s)
Dual x-ray absorptiometry
Other Intervention Name(s)
DEXA, Bone mineral density
Intervention Description
DEXA is a means of measuring bone mineral density (BMD) using spectral imaging. Two X-ray beams, with different energy levels, are aimed at the bones. Soft tissue absorption is subtracted out, then the bone mineral density (BMD) can be determined from the absorption of each beam by bone.
Intervention Type
Other
Intervention Name(s)
Vertebral Fracture Assessment
Intervention Description
Lumbar/thoracic spine x-ray and labs assessed for bone turnover markers.
