Popis: BK polyoma virus associated nephropathy is increasingly recognized as an important cause of allograft dysfunction among renal transplant recipients. Herein we present the cases of two renal transplant recipients who developed progressive functional deterioration suspicious for BK polyoma virus involvement. One patient had been treated with mycophenolate mofetil (MMF), cyclosporine (CsA), and prednisolone (P), and the second patient with tacrolimus (Tac), MMF, and (P). Using quantitative real-time polymerase chain reactions for BK virus DNA, we monitored the content of BK virus in the blood to evaluate disease progression. The high BK virus load initially detected in the blood samples from these patients decreased in the patient who received MMF, CsA, and P after the reduction of immunosuppression, but not in the patient who was treated with Tac, MMF and P. In contrast to previous reports, our patients had not received treatment with anti-lymphocyte globulin (ALG) or monoclonal anti-CD3 antibody (OKT3) after transplantation. It is concluded that even in the absence of vigorous antirejection treatment, immunosuppressive therapy based on Tac and MMF may carry the risk of BK virus-associated nephropathy. Because BK virus specific antiviral therapy is not available, its course may be monitored by measuring the viral load in blood.
