V. Douzdjian et al., GRAFT OUTCOME IN CADAVER RENAL-TRANSPLANTS TREATED WITH FULL-DOSE CYCLOSPORINE INDUCTION WITHOUT ANTIBODY, IRRESPECTIVE OF GRAFT FUNCTION, Clinical transplantation, 11(4), 1997, pp. 294-298
Cyclosporine (CSA) induction has been shown to prolong delayed graft f
unction which in turn may compromise graft outcome. In this study we r
eport our experience with full-dose CSA induction without antibody tre
atment irrespective of graft function and stress the importance of ach
ieving therapeutic CSA levels in the early post-transplant period. The
records of 293 first cadaver renal transplant recipients who were tra
nsplanted between January 1992 and December 1995 were reviewed. Patien
ts were divided into those who had immediate graft function (IGE n=197
) and the ones who had delayed graft function (DGF, n=96). Twenty-six
(13%) patients in the IGF group and 27 (28%) patients in the DGF group
experienced at least one episode of acute rejection (AR), (P=0.002).
Patient and graft survival rates at 1, 2 and 5 yr were similar in the
IGF and DGF groups. Cox regression analysis revealed that the absence
of both DGF and AR was independently associated with a 0.44 times lowe
r risk of graft failure (P=0.06), whereas AR without DGF was associate
d with a 1.9 times increased risk of graft failure (P=0.02). DGF, with
or without AR, did not affect the risk of graft failure. Logistic reg
ression analysis showed that DGF was associated with a 3.6 times highe
r risk of AR (P=0.003). A non-traumatic cause of donor death and prese
rvation time > 24 h were associated with 1.9 and 2.4 times higher risk
s of DGF (P=0.1, P=0.08), whereas female donor gender reduced the risk
of DGF by 0.6 (P=0.1). In conclusion, our results suggest that full-d
ose CSA induction with achievement of therapeutic target levels in the
early post-transplant period is associated with an acceptable graft o
utcome. Graft outcome was not compromised by delayed function, whereas
acute rejection was an independent predictor of graft failure.
