Background: The effect of pre-transplant dialysis
modality on early graft function is a matter of debate. Although some authors
deny the existence of a significant influence, others suggest that peritoneal
dialysis (PD) affects early graft function favorably, possibly by contributing
to a more physiologic water balance. In the present study, we evaluated the
influence of pre-transplant dialysis modality on early and late graft
function.
Patients and Methods: We studied 745 patients who
underwent a first renal transplantation during 1983–2006, comparing the
records of 44 PD patients [26 male; mean age: 26 ± 9 years (range:
8–56 years)] who received 36 living related and 8 cadaveric renal
transplantations with those of a control group of 44 consecutive hemodialysis
(HD) patients [26 male; mean age: 27 ± 11 years (range: 7–49
years)] for the index cases.
Results: The groups showed no significant differences
in donor type, human leukocyte antigen matching, immunosuppressive protocols,
and duration of dialysis. Also, neither group differed significantly with
regard to incidence of delayed graft function, acute tubular necrosis, wound
infection, systemic viral and bacterial infections, or acute rejection in the
early post-transplant period. In the late post-transplant period, incidences
of chronic rejection, graft failure, and malignancies were also similar.
During the follow-up period, 3 patients in the PD group experienced acute
rejection, 2 developed cytomegalovirus (CMV) disease, and 5 developed various
other infections. In the HD group, 4 patients experienced acute rejection, 1
developed CMV disease, and 8 experienced other infections. Five patients in
the PD group and one in the HD group died with functioning grafts (p
= 0.09). No differences were noted between the groups in the incidences of
post-transplant cardiovascular complications, malignancies, and diabetes
mellitus. In the PD group, 33 patients with functioning grafts are still being
followed, 6 have returned to dialysis, and 5 have died. In the HD group, 38
patients with functioning grafts are still being followed, 5 have returned to
dialysis, and 1 has died.
Conclusions: As a pre-transplant dialysis modality,
neither HD nor PD affects the outcome of renal transplantation.
