BACKGROUND AND OBJECTIVES The aim of this study was to elucidate the role and identity of cytokines involved in febrile non-haemolytic red cell transfusion reactions (FNHTRs). MATERIALS AND METHODS Eighty-one patients experiencing transfusion reactions after receiving packed red blood cells (RBCs) were divided into three groups, as follows, based on the reaction experienced: FNHTRs (n = 60); chills without fever (n = 8); and allergic reaction with urticaria (n = 13). The concentrations of interleukin (IL)-1beta, IL-6, IL-8 and tumour necrosis factor (TNF)-alpha were measured in the packed transfused unit and patients' plasma by using enzyme immunoassays. Wilcoxon's matched-pairs signed test was used to compare the difference in cytokine levels in patients' plasma before and after transfusion. The Kruskal-Wallis test was used first, followed by the Mann-Whitney test, to compare the pretransfusion cytokine levels in patients' plasma between groups and to compare the cytokine levels in packed RBCs transfused to each group of patients. RESULTS The age of the implicated packed RBC was 11.5 +/- 5.7 days. Significant increases were observed in IL-6 (P < 0.001) and IL-8 (P < 0.001) patients' plasma levels, but not in IL-1beta or TNF-alpha levels, in those patients exhibiting FNHTR. No changes were observed in the patients' plasma samples of the other groups. Cytokine levels in the RBC concentrate supernatants were not appreciably elevated. CONCLUSIONS Transfusion of packed RBCs may significantly increase intravascular levels of IL-6 and IL-8 in patients with FNHTRs. |
