Summary

The study aims to investigate the concept of computer based Phosphate Kinetic Modeling (PKM) in the hemodialysis patient population. This computerized algorithm model was developed as a tool to aid physicians in controlling a hemodialysis patient's phosphate level. Once a subject consents to participate in the study, the subject's dietary phosphate intake will be estimated by the modeling program and the appropriate dose of the phosphate binder calcium acetate (PhosLo) will be recommended accordingly. If necessary, the Ca++ concentration of the dialysate will be changed to remove any excess calcium absorbed as the result of an increase in the PhosLo prescription to control phosphorus.

PKM Algorithm

The subject's serum calcium and phosphorus values will be input into PKM in order to determine the required PhosLo prescription. The prescription is determined as the number of gelcaps per day that must be taken by the subject. If PKM determines the number of PhosLo gelcaps per day to be greater than or equal to the subject's current prescription, then PKM will calculate the current Ca++ and phosphate balance. Furthermore, the PKM algorithm will determine the additional number of PhosLo gelcaps needed to achieve neutral phosphate (P) balance with serum P reduced to 5.5 mg/dL. The PKM algorithm also calculates the total P intake between dialyses and along with ePCR also calculates a Phosphorus/Protein Ratio (PPR). This ratio ranges from 8 to 14 in dialysis patients following a renal diet.
