Markers of potassium homeostasis in salt losing tubulopathies- associations with hyperaldosteronism and hypomagnesemia.

BMC Nephrol 2020 Jul 6;21(1):256. Epub 2020 Jul 6.

Division of Nephrology and Dialysis, Department of Medicine III, Medical University Vienna, Währinger Gürtel 18-20, A-1090, Vienna, Austria.

Background: Renal loss of potassium (K) and magnesium (Mg) in salt losing tubulopathies (SLT) leads to significantly reduced Quality of Life (QoL) and higher risks of cardiac arrhythmia. The normalization of K is currently the most widely accepted treatment target, however in even excellently designed RCTs the increase of K was only mild and rarely normalized. These findings question the role of K as the ideal marker of potassium homeostasis in SLT. Read More

[Bartter-Gitelman syndromes].

Nephrol Ther 2020 Jul 1. Epub 2020 Jul 1.

Département de génétique, hôpital européen Georges-Pompidou, 20, rue Leblanc, 75015 Paris, France; Centre de Référence de maladies rénales rares de l'enfant et de l'adulte (MARHEA), Paris, France.

Bartter-Gitelman syndromes are rare inherited autosomal recessive salt-losing tubulopathies characterized by severe and chronic hypokalemia associated with metabolic alkalosis and secondary hyperaldosteronism. Bartter syndrome results from a furosemide-like defect in sodium reabsorption in the Henle's loop leading to hypercalciuria and defect in urinary concentration capacity. The antenatal Bartter syndrome is defined by polyhydramnios and an infantile polyuria with severe dehydration whereas classic Bartter syndrome appears during childhood or adulthood. Read More

A Retrospective Clinical Investigation of the Safety and Adverse Effects of Pantoprazole in Hospitalized Ruminants.

Front Vet Sci 2020 17;7:97. Epub 2020 Mar 17.

Veterinary Diagnostic and Production Animal Medicine, College of Veterinary Medicine, Iowa State University, Ames, IA, United States.

Clinical safety data for the use of gastroprotectants in hospitalized ruminants is lacking. In human patients, multiple adverse effects are possible from the use of pantoprazole including hematologic and electrolyte abnormalities as well as anaphylaxis and edema. The medical records of all hospitalized cattle, goats, and sheep administered pantoprazole over an ~5-year period were retrospectively analyzed for adverse effects. Read More

Relation of Low Serum Magnesium to Mortality and Cardiac Allograft Vasculopathy Following Heart Transplantation.

Am J Cardiol 2020 May 5;125(10):1517-1523. Epub 2020 Mar 5.

Heart Transplantation Unit, Leviev Cardiothoracic and Vascular Center, Sheba Medical Center, Israel; Sackler School of Medicine, Tel Aviv University, Israel. Electronic address:

Hypomagnesemia is commonly observed in heart transplant (HT) recipients receiving calcineurin inhibitors. Since low serum magnesium (s-Mg) has been implicated in the progression of atherosclerosis, potentially leading to worsening coronary heart disease, arrhythmias and sudden death, we investigated the association between s-Mg and HT outcomes. Between 2002 and 2017, 150 HT patients assessed for s-Mg were divided into high (≥1. Read More

Claudins in Renal Physiology and Pathology.

Genes (Basel) 2020 03 10;11(3). Epub 2020 Mar 10.

Centre de Recherche des Cordeliers, INSERM, Sorbonne Université, Université de Paris, F-75006 Paris, France.

Claudins are integral proteins expressed at the tight junctions of epithelial and endothelial cells. In the mammalian kidney, every tubular segment express a specific set of claudins that give to that segment unique properties regarding permeability and selectivity of the paracellular pathway. So far, 3 claudins (10b, 16 and 19) have been causally traced to rare human syndromes: variants of cause HELIX syndrome and variants of or cause familial hypomagnesemia with hypercalciuria and nephrocalcinosis.
