| Research Abstract |
Ninety four children received living related liver transplantation (LRLT) from June 1990 to April 1994. It is well known that the large dose administration of immunosuppressant is accompanied by a high incidence of bacterial and viral infection and that steroids induce growth retardation. To reduce side effects and growth inhibition, we have been studying to minimized doges of immunosuppressants and develope optimal FK 506 dosing in LRLT.Steroids were withdrawn in 90% of recipients. A new protocol of FK 506 dosing was established with monitoring trough concentration using microparticle enzyme immunoassay method. It is sometimes said that the problem of immune reaction is not a crucial one to liver transplantation due to the liver's supposed to tolerance to immunity compared with heart and kidney transprantation. To evaluate the immunological role of the HLA class II matching between donor and recipient in LRLT, the postoperative clinical course was investigated. The matching of DRB1, DQB1 and DPB1 was revealed to have a beneficial effect in LRLT, while the matching of DQA1 was of a negative effect on graft function. The matching of HLAII should be reevaluated using reliable molecular method and deserve appropriate consideration in LRLT
