Long-term immunosuppression for prevention of nonviral disease recurrence.

The choice of immunosuppressive regime used after liver transplantation depends on many factors, which should include the effect of disease recurrence; recurrence of disease after liver transplantation may be affected by the degree and type of immunosuppression used and recurrent disease may affect patient and graft survival. For autoimmune diseases, recurrence of primary biliary cirrhosis develops sooner and more rapidly in those on tacrolimus compared with cyclosporine, but graft loss from recurrent disease is uncommon; recurrence rates of primary sclerosing cholangitis is unaffected by immunosuppressive regimes and recurrence of autoimmune hepatitis may be reduced by prescription of corticosteroids. Whether the immunosuppressive regime affects the pattern of hepatocellular carcinoma recurrence is uncertain. It is probable that the use of calcineurin inhibitor does not have a significant effect and inhibitors of TOR may have an anti-cancer effect, but this still has to be shown clinically. Most metabolic diseases are not affected by the choice of immunosuppression, although recurrence of sarcoidosis may be prevented by corticosteroids.
