Hyperphosphatemia

Aka: Hyperphosphatemia, High Serum Phosphorus
  1. Causes
    1. Renal Failure
    2. Dehydration
    3. Addison's Disease
    4. Hypervitaminosis D
    5. Hypoparathyroid
    6. Magnesium Deficiency
    7. Milk-Alkali Syndrome
    8. Transfusions
    9. Hemolysis
    10. Sarcoidosis
    11. Bone metastases
    12. Myelogenous Leukemia
  2. Evaluation: Renal Failure
    1. Chronic Renal Failure
      1. Increased phosphate when GFR falls below 20 ml/min
      2. Usually Phosphate in 5-10 mg/dl range
    2. Acute Renal Failure
      1. Especially in oliguric or hypercatabolic forms
      2. Highest in:
        1. Myoglobinuric Acute Tubular Necrosis
        2. Surgery
        3. Trauma
  3. Evaluation: Normal Renal Function
    1. Check Urinary phosphate excretion (Urine pHosphate)
    2. Increased Urine pHosphate: over 1500 mg/dl
      1. Endogenous source
        1. Cytotoxins
        2. Rhabdomyolysis
        3. Malignant hyperpyrexia (Fever)
      2. Exogenous source
        1. Laxative Abuse
        2. Enemas
        3. Phosphate (Oral, IV, or Poisoning)
    3. Normal Urine pHosphate: Under 1500mg/dl
      1. Increased reabsorption
        1. Hyperparathyroidism
        2. Menopause
        3. Extracellular Fluid Volume contraction
        4. Tumoral calcinosis
  4. Management
    1. Antacid binding gel: Aluminum hydroxide (AlternaGel)
      1. Dose 600 mg/5 ml, 5 ml qid with meals and at bedtime
    2. Low Phosphate diet

Hyperphosphatemia (disorder) (C0085681)

Definition (NCI) Abnormally high level of phosphate in the blood.
Definition (MSH) A condition of abnormally high level of PHOSPHATES in the blood, usually significantly above the normal range of 0.84-1.58 mmol per liter of serum.
