Background
Major Causes
- Increased phosphate intake (Vitamin D, laxative abuse)
- Increased renal reabsorption (Hypoparathyroidism)
- Decreased excretion (Renal failure)
- Transcellular shifts (Tumor lysis syndrome, Rhabdomyolysis)
Clinical Features
- Fatigue
- Shortness of breath
- Anorexia
- Nausea
- Vomiting
- Insomnia
Differential Diagnosis
- Calciphylaxis
- Vitamin D intoxication
- Tumor lysis syndrome
- Laxative (Phospho-soda) abuse
- Rhabdomyolysis
- Hypoparathyroidism
- Pseudohypoparathyroidism
- Multiple myeloma
Evaluation
- >4.5mg/dL[1]
Labs
Symptoms usually related to associated renal failure, hypocalcemia or hypomagnesemia
- Metabolic Panel (with calcium, Magnesium, and Phosphorus)
Management
Hyperphosphatemia treatment
- Treat the underlying cause
- Restrict calcium phosphate intake
- IV Normal Saline (if normal renal fx)
- Acetazolamide (500mg IV q6hr) - if normal renal function
- Phosphate Binder - Aluminum hydroxide (50-150mg/kg PO q4-6h) - limited effect
- Dialysis if refractory
Disposition
