Ix et al note a trough at 8 AM, with peaks at 4 AM and 4 PM. Serum phosphate levels follow a circadian rhythm, which must be considered when interpreting patient Therefore, when CKD develops and hyperphosphatemia ensues, the sole means of controlling it is limitation of intake. Because intestinal absorption of phosphate and phosphate content in a typical diet is high, maintenance of phosphate homeostasis is dependent on renal excretion of the ingested excess. The clinical condition most often requiring curtailment of ingestion is CKD. Įnhancement of renal excretion of phosphate: Hyperphosphatemia due to tumor lysis responds to enhancement of urinary losses through forced saline diuresis Recommendations, as approximately 40-60% of animal-based phosphate is absorbed, compared with 20-50% of plant-based phosphate, and that fresh and homemade foods are preferable to processed foods, which often contain inorganic phosphate additives.
Limitation of phosphate intake: Patients with chronic kidney disease (CKD) are advised to avoid foods that are especially high in phosphate high-phosphate foods include dairy products meats, nuts, and other high-protein foods processed foods and dark colas. Kidney Disease: Improving Global Outcomes (KDIGO) guidelines note that it is reasonable to consider phosphate source in making dietary Phosphate binders with no aluminum or calciumĭiagnosis of the cause in order to initiate specific therapy: For example, patients with hyperphosphatemia due to administration of liposomal amphotericin B who continue to require antifungal therapy may be switched to the amphotericin B lipid complex formulation, which contains less inorganic phosphate.
