[Research progress of graft-versus-host disease after liver transplantation]

Graft-versus-host disease (GVHD) is an uncommon but fatal complication of orthotopic liver transplantation (OLT). The pathogenesis and mechanism of GVHD after OLT remains unclear and the treatment is therefore largely empirical. The prevention of GVHD including avoidance of closely matched human leukocyte antigen donors and old-age recipients is of particular importance because effective treatment is lacking. To reduce immunosuppressants combined with high dose of methylprednisolone and IL-2 receptor antibodies can be applied as a reasonable regime.
