Abstract: Graft-versus-host disease (GVHD) is the major complication of allogeneic hematopoietic stem cell transplantation (HSCT), and cytokines are recognized as important mediators of GVHD. Polymorphisms in the regulatory regions of several cytokine genes have been associated with a number of immune diseases as well as organ transplant complications. In this study we have investigated the role of tumor necrosis factor-alpha(-308). interleukin (IL)-6(-174), IL-10(-1082, -819), (-592), Interferon-gamma(-874), and transforming growth factor-beta 1 (+869, +915) polymorphisms on HSCT outcome. Donor/recipient genotypes were analyzed by polymerase chain reaction with sequence specific primers (PCR-SSP). Although we have found a small number of low IL-6, a polymorphism at position -174 of the recipient and donor IL-6 gene was associated with the increased incidence of chronic GVHD. Therefore, this study emphasizes the probable potential role of genetic variability of donor and recipient in determining outcome after transplantation. (c) 2005 Elsevier Ltd. All rights reserved.
