Two-year reduction of panel reactive human leukocyte antigen antibodies in children receiving mycophenolate mofetil after valved allograft placement.
Allografts used in the repair of congenital heart defects in children induce a persistent broad HLA antibody response. We have previously shown that a 3-month course of mycophenolic mofetil (MMF) significantly reduces the HLA class I antibody response to valved allograft implantation in children. The purpose of this study was to determine if this reduction in HLA antibody persists after discontinuation of MMF. We conducted follow-up (mean 2 +/- 0.5 years) of seven patients who had received allograft placement for repair of congenital heart defects. These patients received 3 months of immunosuppression with MMF following allograft implantation. When compared to historical controls, patients who received MMF following surgery showed a significantly decreased HLA class I antibody response at 2 years postimplantation. This study demonstrates the ability to persistently alter the HLA class I antibody response using 3 months of MMF following allograft implantation in children.
