  Purpose

This is a prospective, validation study of a extempore made tracer compared with a commercial. Studies with tracer have no medical effects but are used for studying human physiology, in this case pharmacokinetic variables of endogenous albumin distribution and turnover at different levels of inflammation.

  1. Primary Objective:

    - Do the extempore made tracer 123-iodine labeled albumin an commercially manufactured SERALB-125 give identical values of calculated blood plasma volume and capillary leakage measured as transcapillary escape rate of albumin?

  2. Secondary Objective:

    • How do three different measures of albumin turnover correlate in volunteers?
    • How do the pharmacokinetic parameters of endogenous albumin vary between the three study groups?

Primary Outcome Measures:
  • Transcapillary Escape Rate (TER)of Albumin [ Time Frame: 42 days ] [ Designated as safety issue: No ]
    Is the measured value for 123-I-HSA and 125I-HSA identical/equal regarded TER and plasma volume (PV)?


Secondary Outcome Measures:
  • Fractional catabolic rate (FCR) [ Time Frame: 42 days ] [ Designated as safety issue: No ]
    Non compartmental analysis (NCA) and AUC (time-conc) will be determine the pharmacokinetics like clearance, distribution volume and absolute catabolic rate


Other Outcome Measures:
  • plasma albumin turnover rate [ Time Frame: 42 days ] [ Designated as safety issue: No ]
    How well does the variables FSR, FCR1, FCR30 correlate? How does the pharmacokinetic parameters differ/varies between the three groups?
