Since its beginning, graft rejection remains the key problem of solid organ transplantation. This reaction of the recipient's immune system against mismatched antigens of the transplanted organ causes graft damage and consequently loss of its function. Rejection involves cellular (lymphocyte mediated) and humoral (antibody mediated) mechanisms. Among the genetic factors which may have a prognostic value in rejection risk evaluation are the Human Leukocyte Antigens (HLA) genotype, the Killer Immunoglobuline-like Receptor (KIR) gene repertoir, cytokine and other gene polymorphisms. These factors could be screened for before transplantation to find the best possible combination of genetic characteristics of the donor and recipient and to reveal patients with "risky" genotypes, who may need more intensive immunosuppression and more careful post-transplant follow-up. Molecular factors, such as HLA and non-HLA antibodies, soluble CD30 molecule (sCD30), Hepatocyte Growth Factor (HGF) and other cytokines, measured before and/or after transplantation in the recipient's blood may be helpful for rejection risk estimation and may also be used as post-transplant rejection onset markers. In our study, we focused on some of the above mentioned factors. We found that ethnicity plays a significant role in the...
