The potential risks, including hyperphosphatemia and hypocalcemic coma should be kept in mind of primary care physician.

End-stage renal disease (ESRD) is a common disease encountered in clinical practice and is associated with increasing metabolic derangements through disease progression. Phosphate retention is one of the most common derangements and is associated with increased mortality. Hyperphosphatemia becomes increasingly prevalent as glomerular filtration rate decreases. Non-calcium phosphate-binding resi...

In untreated serum of three patients with multiple myeloma, concentrations of inorganic phosphate ranged from 130 to 270 mg/L as measured with a chromogenic assay based on the interaction of phosphate ion with ammonium molybdate in the presence of ferrous sulfate. There were no clinical features of hyperphosphatemia, and values for total calcium concentration in serum remained within normal lim...
