Plasma interleukin 2 receptor levels in renal allograft recipients.
Shed/soluble interleukin 2 receptor (IL2R) was measured by an enzyme-linked immunosorbent assay (ELISA) in serial samples of plasma from 32 patients with renal allografts. Patients on chronic dialysis (pretransplant) had elevated IL2R levels which fell toward normal after transplantation. Patients with acute rejection and viral infection had significantly higher levels of plasma IL2R than did patients with stable renal function or with cyclosporine nephrotoxicity (all P less than 0.005). Acute renal failure from other causes (renal artery stenosis, hemolytic-uremic syndrome) did not have a comparable rise in IL2R. The assay of shed/soluble IL2R may have diagnostic value in the clinical management of allograft recipients, a possibility that deserves further clinical evaluation.
