RUFINO HERNANDEZ, J. Margarita et al. Induction treatment by combining immunoglobulins, plasmapheresis and rituximab in hypersensitive patients receiving cadaveric renal allograft. Nefrología (Madr.) [online]. 2010, vol.30, n.2, pp.252-257. ISSN 1989-2284.

In our Universitary Hospital of Canarias we iniciated in May 2008 a induction therapy protocol for sensitized patients receiving cadaveric renal graft using intravenous immunoglobulins, plasmapheresis and rituximab plus immunosuppression with prednisone, tacrolimus and mycophenolate mofetil. We present the results of four patients. Everyone had anti-HLA antibodies rate (PRA by CDC) more than 75%, were on a waiting list during 4 to 17 years and follow-up time was 10-14 months after transplantation. Patient and graft survival in this period was 100%. Only one patient suffered a humoral acute rejection and another one cellular rejection, in both cases reversible with treatment. During the first year, no evidence of de novo donor-specific antibodies was detected. All patients had significantly reduced the CD19+ cells percentage after infusion of rituximab. Neurological symptoms suggestive of progressive multifocal leukoencephalopathy or serious viral infections after transplantation have not been observed. Additionally, no immediate side effects were observed after administration of medication. In summary, induction therapy by combining immunoglobulin, plasmapheresis and rituximab in hypersensitive patients allows the realization of deceased kidney transplantation with good results in the short and medium-term without serious side effects. It remains to know whether this success will continue in the long term.
