Association Between Serum 25-Hydroxyvitamin D and Bone Metabolism in Patients on Hemodialysis: Tokai Dialysis Cohort Study (KIDNEY WEEK 2025) - "Patients with higher serum 25(OH)D levels were more likely to be female; were less likely to have diabetes, a history of cerebral infarction, or peripheral arterial disease; had higher serum albumin and creatinine levels; and were more frequently prescribed lanthanum carbonate and active vitamin D. There was no association between 25(OH)D levels and serum calcium, phosphorus, or intact parathyroid hormone (PTH) levels...These findings suggest that vitamin D deficiency has at most a limited impact on bone metabolism in patients undergoing hemodialysis. Further studies are needed to clarify the role of 25(OH)D in bone metabolism in kidney failure."

Oxylanthanum Carbonate Achieves Serum Phosphate Control with Significantly Lower Pill Burden in Patients with Hyperphosphatemia on Dialysis (KIDNEY WEEK 2025) - "Pretrial PB included sevelamer carbonate, calcium acetate, ferric citrate, and sucroferric oxyhydroxide. Combined with previously presented safety data, these findings suggest that OLC is safe, effective, and well-tolerated. Its small, easy-to-swallow formulation may be a welcome choice for pts with HP."

Comparative Phosphate-Lowering Effects of Tenapanor in Combination with Different Phosphate Binders in Patients on Hemodialysis: A Prospective Pilot Study (KIDNEY WEEK 2025) - "Methods In this prospective study, 55 HD patients were stratified into five groups based on their baseline phosphate binder (PB) use: PB-naïve, calcium-based binders, iron-based binders (ferric citrate), lanthanum carbonate, and polymer-based binders. Although the exact mechanism remains unclear, it is hypothesized that iron-based binders such as ferric citrate may alter intestinal pH—potentially affecting the local action of tenapanor. These preliminary results highlight the importance of binder selection in maximizing tenapanor efficacy and warrant further mechanistic and clinical studies."

Lanthanum Carbonate-Induced Gastritis Presenting with Melena in a Patient with End Stage Renal Disease (ACG 2025) - "A trial of omeprazole twice daily provides no relief. In patients with unexplained upper GI symptoms or melena on lanthanum therapy, it is important to consider biopsy even in the setting of normal endoscopy. Discontinuation of lanthanum carbonate and switching to alternative binders often leads to symptom resolution."

Crystalline Colitis: A Rare Adverse Effect of Sevelamer Therapy (ACG 2025) - "Home medications included sevelamer carbonate dosed at 2400mg three times daily...Given the presence of sevelamer crystals, the medication was discontinued and replaced with lanthanum carbonate. Sevelamer-induced colitis should be considered in dialysis patients presenting with unexplained colitis, especially when infectious and ischemic causes have been ruled out...Delayed recognition may lead to unnecessary treatments, prolonged symptoms, and increased morbidity. Early identification and discontinuation of sevelamer, with substitution by an alternative phosphate binder, are essential for symptom resolution and prevention of further gastrointestinal injury.Figure: Images A, B, C: Diffuse, severe inflammation found in the proximal transverse colon during colonoscopy."

Lanthanum carbonate does not reduce urinary oxalate excretion in hyperoxaluric kidney stone formers (ERA 2025) - "Short-term treatment with LaCa at doses up to 1500 mg did not reduce urinary oxalate excretion in kidney stone formers with idiopathic hyperoxaluria. Urinary phosphate excretion decreased slightly without effect on serum phosphate levels. LaCa in its current formulation is not a good treatment for the reduction of urinary oxalate excretion in kidney stone formers with idiopathic hyperoxaluria."

Tenapanor administration combined with phosphate binders provides synergistic phosphate lowering effect (ERA 2025) - "Six types of P binders had been used in Group Ad (sevelamer hydrochloride, bixalomer, calcium carbonate, ferric citrate, sucroferric oxyhydroxide hydrate and lanthanum carbonate hydrate). Oral administration of tenapanor significantly reduced P adsorption and improved serum P level in patients undergoing HD either when it was administrated alone or adding on P binders. This P absorption reduction effect of tenapanor was greatly enhanced when it was added on P binders. The mechanism of this synergistic effect would be an important research question."

Gastric Mucosal Calcinosis Case Study: A Diagnosis to Consider in People with Kidney Failure and Gastrointestinal Symptoms?

There is no prevalence, or outcome, data reported for gastric mucosal calcinosis; it may be underdiagnosed. The calciphylaxis rare disease registry, and UK renal registry, may offer an opportunity to undertake research to better understand the disease process, risk factors and prevalence."
