The Effect of Rituximab on the Development of Anti-Donor Antibodies

Completed · Not applicable

Conditions studied: Renal Transplant Rejection

In brief

The aim of the study is to find out if Rituximab, which is an antibody against specific white cells involved in rejection, when combined with standard anti-rejection treatment can more effectively reverse the rejection process. Our hypothesis is that with acute rejection there is activation of B cells and the subsequent development of anti-donor antibodies that ultimately lead to graft loss. More effective therapy targeted at B cells may abort the development of anti-HLA antibodies, prevent renal injury and have a favorable effect on long-term graft outcome.
