Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Randomised trial comparing the impact of two different phosphate binders (lanthanum carbonate vs calcium carbonate) on vascular calcification and arterial stiffness in haemodialysis patients over 18 months. Group 1 will receive lanthanum carbonate 750mg three times daily, increasing to max 3750mg daily, and Group 2 will receive calcium carbonate 1500mg three times daily (with equivalent 600mg caclium tds), with increase to max 9 tablets daily, aiming for serum phosphate <1.7 in both groups. Both medications will be administered orally and with meals.
