Abstract:
Blood transfusion immunomodulatory effects are reported in many clinical situations. Underlying mechanisms, especially the difference between autologous and allogeneic blood transfusion, are still unclear. Therefore, patients with curative surgery for colorectal cancer were randomized to an autologous blood group (autoG) donating blood preop or to an allogenic blood group (alloG). From 24 patients, blood was taken before blood donation, prior to surgery and at day 3 and 8 postop. Using a fluorescence-cytotoxicity assay, NK and LAK activity were determinated. Blood of 56 patients was drawn preop. and at day 7 postop.; sIL-2R, TNF-alpha, sTNF-alphaR, IL-10 and specific IgG following tetanus-toxoid vaccination were measured by ELISA. After similar decline of NK and LAK activity from surgery to day 3 in both groups (p=0.028/0.012), which doubled to day 8 in alloG,in contrast in autoG recovery from day 3 to 8 in was observed. Both groups postop. showed increase of sIL-2R, TNF-alpha (p=0.01), sTNF-alphaR (p=0.02) and tetanus-IgG. Increase in autoG (deltaTNFalpha=4.9 U/ml) was higher than in alloG (2.0 U/ml), whereas sTNF-alphaR and tetanus-IgG were higher in alloG. sTNF-alphaR acts competitively to TNF-alpha, what might explain the reduced TNF-alpha effect in alloG. Patients of alloG showed postop. Ten-fold increase of IL-10 compared to autoG (p=0.019).These findings indicate immunomodulatory potential of blood donation best explained by the hypothesis of Th1/Th2 shift of pre-Th-cells: Allog. blood transfusion might induce Th2 response, whereas autol transfusion might create Th1 type, which is seen to be more beneficial to patients' course after cancer surgery.
