Cytokines and soluble tumour necrosis factor I receptor levels during pretransplant conditioning in allogeneic stem-cell transplantation

We investigated a broad range of cytokines in plasma samples drawn daily immediately before start of pretransplant conditioning and during the conditioning. The presented data indicate that single-day measurements of inflammatory cytokines during conditioning may lead to unreliable conclusions concerning their prognostic significance. However, serial quantitation of soluble tumour necrosis factor receptor I (sTNFRI) is more likely to reflect the degree of inflammatory activation induced by pretransplant conditioning.
