    Abstract

    The purpose of this study was to characterize cytokine responses during conditioning in patients undergoing allogeneic stem cell transplantation (SCT) with the aim to identify which markers that may reliably reflect inflammatory activity during conditioning. We investigated inflammatory and anti-inflammatory mediators in plasma samples drawn daily during the conditioning of 20 patients. Soluble tumour necrosis factor alpha receptor I (sTNFRI) increased during the conditioning reflecting the type of conditioning given. Antithymocyte globulin (ATG) was the most potent inducer of sTNFRI (288% increase (median) P=0.002), followed by VP-16 (184%, P=0.03), cyclophosphamide (129%, P=0.03) and total body irradiation (148%, P=0.0005). Administration of i.v. busulfan (Busilvex; BU) was not associated with significant changes in sTNFRI levels. At day 0 (the day of stem cell infusion) the sTNFRI levels were not only elevated compared with baseline (188% increase), P
