Lithium hypercalcemia mechanism
Web11 feb. 2024 · Hypercalcemia develops when the entry of calcium into the serum surpasses its urinary excretion or skeletal deposition. It occurs in the setting of excessive bone resorption, accelerated gastrointestinal absorption, or reduced renal excretion of calcium. Web1 mrt. 2016 · Hypercalcemia was identified a mean 5.2 years (median, 3.9 years) after thiazide initiation (range, 4 days to 33 years). The average highest serum calcium was 10.72 mg/dL [2.67 mmol/L] (range, 10.2 to 12.5 mg/dL [2.5–3.1 mmol/L]). Most subjects were treated with thiazides for hypertension (94%).

The reversible decrease in glomerular filtration rate in severe hypercalcemia is thought to be mediated in part by direct renal vasoconstriction. This has been shown in a study comparing renal blood flow and glomerular filtration rates in hypercalcemic and normocalcemic rats [ 3 ].
WebThe mechanism by which lithium causes hyperparathyroidism is unclear. The parathyroid glands regulate calcium homeostasis through the actions of their hormone PTH.
