The calculation of treatment delivered to PD patients requires the collection of PD effluent, plasma and urine samples. 125I-Iothalamate plasma disappearance, which eliminates the need for PD effluent collections, was tested as an alternate method to measure the weekly PD treatment delivered. Two protocols were designed. In protocol A, a 35 microCi dose of 125I-Iothalamate was injected in three subjects and allowed to equilibrate. A plasma sample was taken and patients returned on both of the following two days with timed labeled effluent bags and a 24-hour urine collection for each day. The timed PD effluent and 24-hour urine collections were measured for 125I-Iothalamate, urea and creatinine concentrations. 125I-Iothalamate and urea clearances were strongly correlated for both PD (R2 = 0.76, n = 24) and renal (R2 = 0.92, n = 6) clearances. In protocol B, thirteen subjects were given a 35 microCi injection of 125I-Iothalamate. A blood sample was taken one hour post injection and a second blood sample taken on day five. Kt/V were calculated from the 125I-Iothalamate plasma disappearance curve and compared to weekly Kt/V values extrapolated from one day's collections (Traditional Method). The comparison of Kt/V values found by 125I-Iothalamate Method vs. the "Traditional Method" yielded R2 = 0.79, n = 13. In conclusion, the plasma disappearance of 125I-Iothalamate is an alternate method of determining weekly Kt/V, over an extended period of time, which eliminates the need for PD effluent collections.
