The Calcium-sensing receptor (CaSR) has only a PTH-dependent role in the acute response of renal phosphatetransporters to phosphate intake
Am J Physiol Renal Physiol. 2024 Mar 28. doi: 10.1152/ajprenal.00009.2024. Online ahead of print.ABSTRACTThe kidney controls systemic inorganic phosphate (Pi) levels by adapting reabsorption to Pi intake. Renal Pi reabsorption is mostly mediated by sodium-phosphate cotransporters NaPi-IIa (SLC34A1) and NaPi-IIc (SLC34A3) which are tightly controlled by various hormones including parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23). PTH and FGF23 rise in response to Pi intake and decrease NaPi-IIa and NaPi-IIc brush border membrane abundance enhancing phosphaturia. Phosphaturia and transporter regulation occur ...

Identification and characterization of a novel CASR mutation causing familial hypocalciuric hypercalcemia
ConclusionThis novel CASR I554N mutation causing FHH attenuates CASR stability, its binding affinity with Ca2+, and the response to eCa2+ corrected by therapeutic calcimimetics. (Source: Frontiers in Endocrinology)

Comparative efficacy of sodium thiosulfate, bisphosphonates, and cinacalcet for the treatment of vascular calcification in patients with haemodialysis: a systematic review and network meta-analysis
Up to now, there is no unequivocal intervention to mitigate vascular calcification (VC) in patients with hemodialysis. This network meta-analysis aimed to systematically evaluate the clinical efficacy of sodiu... (Source: BMC Nephrology)

The authors reply
In podocyte-specific calcium-sensing receptor knockout mice, we recently demonstrated a role of calcium-sensing receptor signaling in control of glomerular disease and the therapeutic potential of calcimimetics.1,2 Off-label therapy with cinacalcet together with oral calcium in 4 children with nephrotic syndrome was well tolerated, reduced proteinuria by up to 96%, and resolved edema. Early viral infection –related relapses, however, suggested that the effect of calcium-sensing receptor stimulation was counteracted by additional immunologic triggers. (Source: Kidney International)

Cinacalcet in focal segmental glomerular sclerosis: a case report
We read with interest the article by M ühlig et al.,1 recently published in Kidney International. Drug-resistant focal segmental glomerular sclerosis is an open issue, and these patients often rapidly progress to end-stage renal disease.2 In such a setting, any potential new drug is welcome.3 The authors demonstrated that calcium-sensi ng receptor knockout mice manifest up to 3 times proteinuria with respect to wild-type mice when treated with adriamycin. Moreover, the administration of cinacalcet to wild-type mice significantly reduced proteinuria in this model. (Source: Kidney International)

Chronic Cinacalcet improves skin flap survival in rats: the suggested role of the nitric oxide pathway
Naunyn Schmiedebergs Arch Pharmacol. 2024 Jan 6. doi: 10.1007/s00210-023-02922-7. Online ahead of print.ABSTRACTCinacalcet is a calcimimetic medicine that has been used to treat secondary hyperparathyroidism and parathyroid cancer. Various studies have proposed the positive role of calcium and its receptor in skin wound healing. Furthermore, Cinacalcet interacts with other skin repair-related mechanisms, including inflammation and nitric oxide pathways. The present study evaluated the effect of Cinacalcet on the random-pattern skin flap survival. Eighty-four Wistar male rats were used. Multiple doses of Cinacalcet (30, 3, ...

< em > GCM2 < /em > p.Tyr394Ser variant in Ashkenazi Israeli patients with suspected familial isolated hyperparathyroidism
CONCLUSION: In contrast to previous observations, the GCM2 p.Tyr394Ser variant-associated phenotype may be mild in AJ with FIHP, sometimes mimicking FHH. Because surgery may be curative, surgeons should be aware of the possibility of multiple gland diseases in these patients. The clinical spectrum and clinical utility of screening for this variant warrant further investigation.PMID:38130397 | PMC:PMC10733520 | DOI:10.3389/fendo.2023.1254156 (Source: Atherosclerosis)

Treatment of Hypercalcemic Hyperparathyroidism After Kidney Transplantation Is Associated With Improved Allograft Survival
CONCLUSIONS: This study demonstrates that treatment of hypercalcemic tertiary HPT post-KT is associated with improved allograft survival. Although these findings are not specific to hypercalcemia of malignancy, they do demonstrate the negative impact of hypercalcemic tertiary HPT on kidney function. Hypercalcemic HPT should be screened and aggressively treated post-KT.PMID:38006197 | DOI:10.1093/oncolo/oyad314 (Source: The Oncologist)
