U.O. e Sezione di Nefrologia, Brescia DIALISI PERITONEALE E TRAPIANTO Mister Chairmen, Dear Colleagues, I’d like to thank the Organizing Committee for inviting me to talk in this very important and historical Course. Claudio has asked me to talk about “TRANSPLANTATION OUTCOME IN PATIENTS ON PD and HD” Giovanni Cancarini U.O. e Sezione di Nefrologia, Brescia

pre-operation – operation – post-operation Tx pre-operation – operation – post-operation HD necessità di seduta HD prima dell’intervento per: - distanza da dialisi precedente - iperkaliemia - Prolunga il tempo d’ischemia fredda - Espone a bioincompatibilità An advantage for PD patients consists on the fact that they are always ready for the transplant operation, they need only flushing out the peritoneal fluid. HD patients generally need to be dialyzed, for three-four hours before the operation and this could increase the cold ischemia time. PD: pazienti sempre pronti per il Tx (salvo intercorrente peritonite o ESI)

Also in the study of Bleyer there is a significant difference, However, it must be defined the role of a so little difference on clinical results (two hours in the first study and less than half an hour in the Bleyer study.

TX in PD vs. TX in HD In the past, some Nephrologists and Surgeons had a negative attitude towards Peritoneal Dialysis as a dialytic modality before kidney transplantatio . This opinion was probably based more on impression than on scientific data, even though, during the ‘80s and the beginning of the ‘90s PD was suggested in some papers as a “risk factor in renal transplantation”. Later, many papers did a methodologically correct approach to this topic, but their results did not fully agree; e.g., Passalacqua et al. strongly pointed out an advantage for patients receiving HD before K-Tx. On the contrary, Vanholder at al. considered PD as a first choice therapy, as a pre-transplantation therapeutic modality.

TX in PD - il passato - (Guillou PJ, et al. Br J Surg. 1984; 71:878) 1984 CAPD: a risk factor in renal transplantation? (Guillou PJ, et al. Br J Surg. 1984; 71:878) 1999 Our data strongly suggest an advantage for patients receiving HD just before transplantation with significant decreases in rate of infections, rates of rejection, and length of hospital stay. (Passalacqua Jo-A, et al. Transplantation 1999; 68:535) … peritoneal dialysis should be considered as a first choice for pre-transplantation therapeutic modality (Vanholder R, et al. Am. J. Kidney Dis. 1999; 33:934) In the past, some Nephrologists and Surgeons had a negative attitude towards Peritoneal Dialysis as a dialytic modality before kidney transplantatio .

PROBABILITY TO BE TRANSPLANTED HD (219,240 patients) vs PROBABILITY TO BE TRANSPLANTED HD (219,240 patients) vs. PD (33,162 patients) (patients starting therapy for ESRD between 1995-1998) PD (p<0.001) HD On the other hand, there is the observation of Snyder on the Medicare and Medicaid transplanted patients in the period 1995-1998. After five years, the 32% of PD patients had been transplanted against only the 16% on HD. After adjustments were made for the differences between PD and HD patients, the relative probability of receiving a kidney transplant was about 40% greater for PD than for HD patients. Those Authors conclude that ”There may be a perception among patients and their physicians that peritoneal dialysis is the treatment of choice for transplant candidates. … transplant candidates were more likely to be placed on PD than HD.” Relative likelihood of receiving a kidney transplant was 1.39 times greater for PD than for HD patients. There may be a perception among patients and their physician that PD is the treatment of choice for transplant candidates. …. transplant candidates were more likely to be placed on PD than HD. (Snyder JJ et al. Kidney Int. 2002; 62:1423-1430)

Characteristics of patients on waiting list according to the ESRD treatment modality The French Collaborative Group found that PD patients on waiting list were younger, with an higher percentage of women, a lower prevalence of diabetes. It is very interesting to note that, at the time of registration, PD patients had spent 11 months on dialysis versus about 20 months of those on HD. This could bring to hypothesize that the physicians involved in PD programs are more efficient in enrolling their patients in the waiting list. Chalem Y et al. Kidney Int. 2005; 67:2448-2453

IMMEDIATO POST-TRAPIANTO About the short term outcome

RITARDATA RIPRESA FUNZIONALE DP vs. HD PD HD 16% 31% p<0,05 Delayed graft function could depend on many factors related to donor (e.g.: age, non-heart-beating donor, clinical status just before operation), kidney (e.g.: cold ischemia time, difficulty in perfusion), recipient (fluid, vascular and cardiac status, ability to metabolize immunosuppressive drugs) and kind of immunosuppressive therapy . DGF could depend on either acute tubular necrosis or acute rejection which could be easily differentiated only when renal biopsy is done; unfortunately, many papers report all those data together. In our center the probability of delayed graft function is about twice in HD patients. Sezione Trapianto di Rene - Nefrologia Brescia

In the most of these papers the ratio of delayed graft function between HD and PD is about 2. The reason for this beneficial effect of PD is not completely understood, but many authors claim the more expanded extracellular volume in PD patients, as the possible cause.

The percentages of graft lost as a result of thrombosis were 3,4 in PD and only 1,9 in HD. In the multivariate analysis, PD plays a significant role, by increasing the risk of thrombosis of about 50%. The authors conclude that, since pretransplant PD is associated with an increased risk of graft thrombosis, special precautions should be undertaken in pediatric renal transplant patients who have received PD, especially infants and young children.

The first line in that of patients transplanted after a very short course on PD (less than 2 weeks); the last line refers to patient on dialysis for more than 5 years. You can se that duration of dialysis has a negative effect both on graft and patient survival. (Goldfarb-Rumyantzev A, et al. NDT 2005; 20: 167–175

That can potentially be explained by the fact that predictors of the graft survival (e.g. oxidative stress, loss of residual renal function, aberrant T, B cell and cytokine production [20]) might be peaking at 1 year. Additional factors affecting recipient survival (e.g. cardiovascular calcification) continue to accumulate after 1 year of dialysis therapy. Since dialysis for up to 6 months does not appear to affect graft survival adversely, these results suggest that patients who have uraemic symptoms should not defer dialysis while waiting for kidney transplant. While the time on the waiting list is still associated with the graft and recipient outcome, duration of pretransplant ESRD is a better predictor of the graft and recipient survival. 0,9 0,92 0,8 1-2 yrs 2-3 yrs 3-5 yrs >5 yrs time on dialysis (drawn from data by: Goldfarb-Rumyantzev A, et al.
