Correlations between plasma strontium concentration, components of calcium and phosphate metabolism and renal function in type 2 diabetes mellitus

Abstract: We found an independent inverse association between eGFR and plasma Sr concentration and an independent association between plasma Sr concentration and plasma FGF23 concentration, a marker of deranged calcium and phosphate metabolism. Further research is needed to determine the mechanisms behind these associations and the impact of an elevation in plasma Sr concentration on bone mineralization and calcification.

“…That Sr is also excessively reabsorbed across the renal tubular epithelium is a sound hypothesis, albeit not documented. Subsequently, patients with HELIX syndrome may have a higher than normal serum Sr concentration, all the more so since serum Sr level increases when GFR decreases 82 . Thus, a higher serum Sr level may result in a higher deposition of Sr in bone and tooth.…”

“…It is much lower than normal glomerular filtration rate, indicating that Sr excreted in urine is only a tiny fraction of filtered Sr: therefore, most of Sr filtered at the glomerulus is reabsorbed along the renal tubule, as Ca and Mg are. 82,83 Patients with HELIX syndrome have very low urinary calcium and magnesium excretion in urine, despite normal serum Ca and high serum Mg levels, indicative of increased tubular Ca and Mg reabsorption. 32 That Sr is also excessively reabsorbed across the renal tubular epithelium is a sound hypothesis, albeit not documented.…”

“…Fibroblast growth factor-23 (FGF-23) is a hormone that plays an important role in vitamin D and phosphate homeostasis [ 77 ]. In patients with T2DM and CKD, increased serum FGF-23 levels were associated with macroalbuminuria and creatinine levels [ 77 , 78 , 79 , 80 ]. In addition, serum FGF-23 levels predicted an increased risk for DKD progression [ 81 ].…”

“…For example, researchers suggested that serum strontium was associated with an increased risk of renal insufficiency ( 13 , 14 ). Besides, serum strontium has been proven to be negatively related to the estimated glomerular filtration rate (eGFR) in the diabetic population ( 15 ). Another study showed that patients with high serum strontium were at an increased risk for acute kidney injury after cardiac surgery ( 16 ).…”
