BACKGROUND Lanthanum carbonate is a non-calcium phosphate binder that is effective for the treatment of hyperphosphatemia. However, it is unknown whether treatment with lanthanum affects survival. METHODS We retrospectively collected data on maintenance hemodialysis patients at 22 facilities (n = 2292) beginning in December 2008, a time point immediately prior to the commercial availability o...

The title compound, [La(C(7)H(3)O(6)S)(H(2)O)](n), forms a three-dimensional framework in which the asymmetric unit contains one La(III) atom, one 5-sulfosalicylate (2-oxido-4-sulfonatobenzoate) ligand and one coordinated water mol-ecule. The La(III) atom is coordinated by nine O atoms from three carboxyl-ate, three sulfonate and two hydroxyl groups, and one water mol-ecule, forming a distorted...

In the title complex, [La(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the La(III) ion is coordinated by one N and three O atoms from two pyrazine-2-carboxylate ligands, by four O atoms from two oxalate ligands and by two O atoms of two water molecules, displaying a distorted bicapped square-anti-prismatic geometry. The carboxyl-ate groups of pyrazine-2-carboxyl-ate and oxalate ligands link the l...

Single crystals of deca-lanthanum(III) dodeca-oxotellurate(IV), La10Te12O39, were obtained by reacting La2O3 and TeO2 in a CsCl flux. Its crystal structure can be viewed as a three-dimensional network of corner- and edge-sharing LaO8 polyhedra with Te(IV) atoms filling the inter-stitial sites. The Te(IV) atoms with their 5s (2) electron lone pairs distort the LaO8 polyhedra through variable Te-...

This method was developed for the determination of trace amounts of aluminum(III) in dialysis concentrates using atomic absorption spectrometry after coprecipitation with lanthanum phosphate. The analytical parameters that influenced the quantitative coprecipitation of analyte including amount of lanthanum, amount of phosfate, pH and duration time were optimized. The % recoveries of the analyte...

BACKGROUND Lanthanum carbonate (FOSRENOL®) is an effective, well-tolerated phosphate binder. The ability of lanthanum to reduce serum phosphorus levels to ≤5.5 mg/dL in patients with end-stage renal disease (ESRD) was assessed in a clinical practice setting. METHODS A 16-week, phase IV study enrolled 2763 patients at 223 US sites to evaluate the efficacy of lanthanum carbonate in controlling ...

In the title complex, di-aqua-(1H-imidazole-κN3)(nitrato-κ2O,O')bis-(4-oxo-pent-2-en-2-olato-κ2O,O')lanthanum(III), [La(C5H7O2)2(NO3)(C3H4N2)(H2O)2], the La atom is coordinated by eight O atoms of two acetyl-acetonate (acac) anions acting as bidentate ligands, two water mol-ecule as monodentate ligands, one nitrate anions as a bidentate ligand and one N atom of an imidazolate (ImH) molecule as ...
