Effervescent Calcium Magnesium Citrate to Prevent Mineral Metabolism and Renal Complications of Chronic Proton Pump Inhibitor Therapy
University of Texas Southwestern Medical Center
Summary
Proton pump inhibitors (PPIs) are widely used for the control of gastric ulcer-gastritis, erosive esophagitis (gastroesophageal reflux disease), peptic ulcer disease (duodenal ulcer), and heartburn. Despite their efficacy, their use has been implicated in possibly causing fragility fractures (osteoporosis), hypomagnesemia (magnesium deficiency) and increased risk of chronic kidney disease (CKD). The current trial represents the investigators ongoing effort to discern whether these complications could be averted by effervescent calcium magnesium citrate (EffCaMgCit).
Description
In the current proposal, the investigators wish to conduct a 1-year treatment trial, directed at obtaining more definitive evidence that EffCaMgCit overcomes all three complications of PPI. Aim 1. To test the hypothesis that EffCaMgCit would prevent/treat osteoporosis, by suppressing parathyroid function and bone resorption, thereby stabilizing bone mineral density (BMD). The critical endpoint will be overall change in BMD T-Score and Z-Score from baseline to the end of study. Secondary endpoints will be the change in serum PTH and C-terminal telopeptide (CTX). Aim 2. To test the hypothesis…
