Forty-two liver transplant recipients and their respective donors were studied, providing a total of 148 posttransplantation serum samples. DC was assessed with real-time quantitative polymerase chain reaction (qPCR) to detect polymorphic markers. DC did not decrease with time post-transplantation and was higher in child recipients versus adults and in recipients of deceased donor liver transplants versus recipients of live donor liver transplants. Higher levels of DC were detected in Rh-positive blood group donors, in O blood group recipients versus A blood group recipients, and in recipients with hepatitis C virus versus recipients with alcoholic cirrhosis. High DC was associated with patients with organ damage due to recurrent disease and rejection. Stable, high levels of DC, in the absence of other major clinical events, may thus be a marker of transplantation tolerance, and this knowledge may help to tailor immunosuppressive treatment. In conclusion, qPCR is a useful technique for DC follow-up in liver transplantation, although the evolution of DC levels should be analyzed in accordance with the clinical outcome of the patient.
