Endogenous interleukin 1 receptor antagonist during human bone marrow transplantation: increased levels during graft-versus-host disease, during infectious complications, and after immunoglobulin therapy.

Abstract：

:In order to understand in more detail the role of endogenous interleukin 1 receptor antagonist (IL-1ra) during bone marrow transplantation, IL-1ra serum levels of 28 patients undergoing allogeneic (n=25) or autologous (n=3) bone marrow transplantation were measured with a commercially available ELISA. In addition, the impact of intravenous immunoglobulin (IVIG) was evaluated by analyzing IL-1ra serum levels before and 2, 5, and 24 hr after IVIG infusion. IL-1ra measurements revealed a nadir of circulating IL-1ra levels 3-5 days after bone marrow transplantation, with an increase during conditioning and hematological reconstitution. Circulating IL-1ra levels were significantly increased in patients with cytomegalovirus (CMV) disease, CMV reactivation, graft-versus-host disease (GVHD), or fever of unknown origin, when compared with time-matched controls without complications. Highest levels were observed in patients with CMV disease (1922+/-388 pg/ml), followed by patients with CMV reactivation (1575+/-435 pg/ml) and GVHD (1178+/-317 pg/ml). The magnitude of IL-1ra increase in GVHD was related to disease severity. Patients with grade III-IV GVHD developed higher IL-1ra levels than did patients with grade I-II GVHD. Lower but still significantly elevated IL-1ra levels were observed during fever of unknown origin (384+/-87 pg/ml). An increase of IL-1ra serum levels followed the administration of IVIG before transplantation and after hematopoietic reconstitution, but not during aplasia, pointing to the important role of hematopoietic cells in the production of IL-1ra. In conclusion, we show that IL-1ra release is related to conditioning regimen, hematopoietic reconstitution, complications of infectious and alloimmune etiology after bone marrow transplantation, and exogenously administered IVIG.
