Immunoreactive vasopressin in end stage renal failure.
Patients with end stage renal failure have been shown to have higher basal concentrations of plasma arginine vasopressin than subjects with normal renal function. Immunoreactive vasopressin was detected in plasma from patients with severe chronic renal failure and a healthy subject at an elution volume identical to that previously determined with synthetic vasopressin. Assay of all fractions yielded identical chromatograms in the renal failure and healthy control groups. We conclude that the plasma immunoreactive vasopressin in end stage renal failure plasma coelutes with synthetic vasopressin and that the elevated concentrations found in these patients are not due to non-specific depression of binding in the vasopressin radioimmunoassay by circulating substances in renal failure.
