The Study of Urinary Biomarkers in Patients With Hypomagnesemia

In this pilot exploratory study, we aim to examine extracellular vesicles (EVs) as biomarkers in urine from up to 15 patients, with up to 10 samples per patient among the patients with a history of hypomagnesemia.

EffCaMgCit to Prevent Mineral Metabolism and Renal Complications of Chronic PPI Therapy

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).

Magnesium Deficiency In Patients Hospitalized in Internal Medicine Wards

Hypomagnesemia is a common entity in the inpatient and outpatient setting. in previous retrospective study hypomagnesemic patients have higher mortality and longer hospitalization. whether hypomagnesemia is merely a marker of poor prognosis, or whether replacing it can improve outcomes is unclear. The current standard of care is to discharge these patients without workup or further treatment, even if patients had received intravenous therapy while hospitalized. The investigator wish to examine prospectively whether giving replacement therapy affects mortality, length of hospital stay and overall well-being. In order to replete intracellular levels and replete magnesium stores, magnesium should be given for several months.

Intracellular Magnesium and Heart Failure

Low magnesium levels are surprisingly common in those with a heart condition known as HFpEF, where the heart pumps well but is too rigid to fill properly with blood. While routine blood tests can check magnesium levels, they don't tell us how much magnesium is actually inside the heart and muscle cells, where it's vital for energy and overall function. Our research aims to get a clearer picture by looking directly at the magnesium inside these cells and understanding its role in the body's energy production and usage. We're also interested in how magnesium levels affect symptoms and the body's handling of sugar. We're using advanced medical imaging techniques, like heart magnetic resonance imaging (MRI) and other heart and muscle function tests, at rest and when the heart is working hard to help answer these questions. We'll compare the magnesium levels inside the cells before and after giving a supplement of magnesium to see if this can make a difference in how the heart and muscles work.
