Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Identification of the mechanisms by which bone contributes to urine citrate could lead to alternative explanations for and approaches to hypocitraturia. This proposal to explore the role of bone in urine citrate addresses the mission of the CMMCR to discover new mechanisms and innovative therapies for diseases of mineral metabolism. The results will be used to apply for extramural funding to further examine the nonrenal regulation of UCit. Hypothesis: Serum citrate is a function of bone citrate formation dependent on both bone mass and bone turnover. 20 subjects with osteoporosis naïve to treatment will be identified to examine bone parameters that correlate with ΔUcit/Δk. Use of potent anti-osteoporotic therapies to increase the likelihood of identifying significant bone turnover and BMD correlations with ΔUcit/Uk will take place in this study. Plan to achieve the following aim: * Correlate ∆ Ucit/∆k in response to acute KCit load with: 1. Bone turnover marker at baseline 2. BMD at baseline 3. Change in bone turnover markers at 1 month and 6 months with each osteoporosis treatment modality (anti-resorptive agents such as Zoledronic acid or Denosumab, or the Anabolic agent Romosozumab) 4. Change in bone mineral density at 6 with each osteoporosis treatment modality (anti-resorptive agents such as Zoledronic acid or Denosumab, or the Anabolic agent Romosozumab)
