    Background: Hypomagnesemia is a known predisposing condition for the appearance of digitalis toxicity. The detection of a genetic form of Mg urinary wasting with hypomagnesemia being caused by a mutation in the γ subunit (FXYD2) of the Na,K-ATPase, the pharmacological target of Digoxin, prompted us to investigate whether Digoxin administration increases urinary Mg excretion.

    Methods: Two groups of subjects, with rapid atrial fibrillation, received intravenous Digoxin (n = 9) or verapamil (n = 8), for heart rate control. Read More

    Digoxin and Hypermagnesuria.

    In a recent issue of Nephron, Abu-Amer et al.[1] reported the presence of hypermagnesuria in patients following acute intravenous administration of digoxin and suggested that the Na+/K+-ATPase γ-subunit, which is the pharmacological target of digoxin, can play a role in this process. Hypermagnesuria induced by digoxin may have important clinical consequences, particularly in the presence of inherited and acquired conditions associated with hypermagnesuria and hypomagnesemia.

    Background: Hungry bone syndrome is a well-established cause of postoperative hypocalcemia in thyrotoxicosis. To date, the incidence of hungry bone syndrome after total thyroidectomy is unclear. This prospective study examined the incidence of postthyroidectomy hungry bone syndrome and its correlation with preoperative bone mineral density. Read More

    A Nonredundant Role for the TRPM6 Channel in Neural Tube Closure.

    In humans, germline mutations in Trpm6 cause autosomal dominant hypomagnesemia with secondary hypocalcemia disorder. Loss of Trpm6 in mice also perturbs cellular magnesium homeostasis but additionally results in early embryonic lethality and neural tube closure defects. To define the mechanisms by which TRPM6 influences neural tube closure, we functionally characterized the role of TRPM6 during early embryogenesis in Xenopus laevis. Read More

    Deletion of claudin-10 rescues claudin-16-deficient mice from hypomagnesemia and hypercalciuria.

    The tight junction proteins claudin-10 and -16 are crucial for the paracellular reabsorption of cations along the thick ascending limb of Henle's loop in the kidney. In patients, mutations in CLDN16 cause familial hypomagnesemia with hypercalciuria and nephrocalcinosis, while mutations in CLDN10 impair kidney function. Mice lacking claudin-16 display magnesium and calcium wasting, whereas absence of claudin-10 results in hypermagnesemia and interstitial nephrocalcinosis. Read More
