Quantitative Visualization of Lanthanum Accumulation in Lanthanum Carbonate-Administered Human Stomach Tissues Using Mass Spectrometry Imaging

Lanthanum carbonate

Encephalopathy caused by lanthanum carbonate

Lanthanum carbonate is a nonaluminum, noncalcium phosphate-binding agent, which is widely used in patients with end-stage chronic kidney disease. Until now, no significant side-effects have been described for the clinical use of lanthanum carbonate, and there are no available clinical data regarding its tissue stores. Here we report the case of a 59-year-old patient who was admitted with confus...

Possibility of lanthanum absorption in the stomach

Lanthanum carbonate (LC) is an orally administered phosphate binder. Its absorption is generally thought to be minimal. We report here the case of an 81-year-old woman who underwent subtotal gastrectomy for gastric cancer after receiving hemodialysis for 1 year and taking LC for 7 months. Lanthanum phosphate compounds were found histologically in the gastric mucosa and a regional lymph node and...

Pharmacology of the Phosphate Binder, Lanthanum Carbonate

Studies were conducted to compare the phosphate-binding efficacy of lanthanum carbonate directly with other clinically used phosphate binders and to evaluate any potential adverse pharmacology. To examine the phosphate-binding efficacy, rats with normal renal function and chronic renal failure received lanthanum carbonate, aluminum hydroxide, calcium carbonate, or sevelamer hydrochloride in sev...

Calciphylaxis responsive to lanthanum carbonate (FOSRENOL) therapy.

Calciphylaxis is a rare and debilitating vasculopathy predominantly seen in patients with renal failure. The proposed mechanism of injury is active vascular calcification with associated elevated parathyroid hormone, hypercalcemia, or hyperphosphatemia. With improved pharmacologic agents including non-calcium containing phosphate binders, vitamin D analogues, calcimimetics, and bisphosphonates,...
