A comparison of transplant outcomes in peritoneal and hemodialysis patients.

♦ BACKGROUND: It remains unclear whether post-transplant outcomes differ according to the pre-transplant dialysis modality (peritoneal dialysis [PD] versus hemodialysis [HD]). We performed a meta-analysis of studies that assessed either post-transplant mortality, graft survival, or delayed graft function (DGF) in both PD and HD patients. ♦ METHODS: Two independent authors searched English-language literature from January 1, 1980, through August 31, 2014, national conference proceedings, and reference lists. We used combinations of terms related to dialysis (hemodialysis, peritoneal dialysis, or renal replacement therapy), kidney transplant, and outcomes. Studies were included if they measured any of the 3 post-transplant study outcomes in both pre-transplant HD and PD. ♦ RESULTS: A total of 16 studies were included in the final analysis. Of these, 6 studies reported adjusted hazard ratio for mortality, pooled adjusted risk ratio: 0.89 (95% confidence interval [CI] 0.82 - 0.97) in favor of PD (p = 0.006). The same 6 studies reported adjusted hazard ratio for graft survival, pooled adjusted risk ratio: 0.97 (95% CI 0.92 - 1.01, p = 0.16). A total of 13 studies reported unadjusted DGF. Pooled odds ratio: 0.5 (95% CI 0.41 - 0.63) in favor of PD (p < 0.005). Significant heterogeneity observed for all outcomes: I2 = 72.7%, I2 = 59.9%, and I2 = 66.8%, respectively. ♦ CONCLUSIONS: Based on these results, pre-transplant PD is associated with better post-transplant survival than HD. Pre-transplant PD was also associated with decreased risk for DGF compared with HD, although these results were unadjusted. There was no significant difference in graft survival between pre-transplant HD and PD. These results suggest that PD may be the preferred dialysis modality for patients expected to receive a transplant.

Association of Pre-Transplant Dialysis Modality and Post-Transplant Outcomes: A Meta-Analysis.

The population of patients with end stage renal disease (ESRD) is increasing, lengthening waiting lists for kidney transplantation. Majority of the patients are not able to receive a kidney transplant in timely manner even though it is well established that patient survival and quality of life after kidney transplantation is far better when compared to being on dialysis. A large number of patients who desire a kidney transplant ultimately end up needing some form of dialysis therapy. Most of incident ESRD patients choose hemodialysis (HD) over peritoneal dialysis (PD) as the modality of choice in the United States, even though studies have favored PD as a better choice of pre-transplant dialysis modality than HD. PD is largely underutilized in the United States due to variety of reasons. As a part of the decision making process, patients are often educated how the choice regarding modality of dialysis would fit into their life but it is not clear and not usually discussed, how it can affect eventual kidney transplantation in the future. In this article we would like to discuss ESRD demographics and outcomes, modality of dialysis and kidney transplant related events. We have summarized the data comparing PD and HD as the modality of dialysis and its impact on allograft and recipient outcomes after kidney transplantation.

Choice of dialysis modality prior to kidney transplantation: Does it matter?

Background: Peritoneal dialysis (PD) and hemodialysis (HD) have been considered the 2 standard pre-transplant dialysis modalities in patients awaiting kidney transplantation. However, the impact of pretransplant dialysis on the short- and long-term post-transplant outcomes remains controversial. Methods: We searched PubMed, EMBASE and the Cochrane central register of controlled trials for this review. Twelve studies were identified by strict screening for the meta-analysis. Results: We found that pretransplant PD patients had a significantly lower incidence of delayed graft function than HD patients, with an OR 0.67 (95% CI 0.62-0.72, p Conclusions: We found that PD was a better choice of pretransplant dialysis modality than HD.

A Comparison of Transplant Outcomes in Peritoneal and Hemodialysis Patients: A Meta-Analysis.

Objective Most patients with uraemia must undergo chronic dialysis while awaiting kidney transplantation; however, the role of the pretransplant dialysis modality on the outcomes of kidney transplantation remains obscure. The objective of this study was to clarify the associations between the pretransplant dialysis modality, namely haemodialysis (HD) or peritoneal dialysis (PD), and the development of post-transplant de novo diseases, allograft failure and all-cause mortality for kidney-transplant recipients. Design Retrospective nationwide cohort study. Setting Data retrieved from the Taiwan National Health Insurance Research Database. Participants The National Health Insurance database was explored for patients who received kidney transplantation in Taiwan during 1998–2011 and underwent dialysis >90 days before transplantation. Outcome measures The pretransplant characteristics, complications during kidney transplantation and post-transplant outcomes were statistically analysed and compared between the HD and PD groups. Cox regression analysis was used to evaluate the HR of the dialysis modality on graft failure and all-cause mortality. The primary outcomes were long-term post-transplant death-censored allograft failure and all-cause mortality started after 90 days of kidney transplantation until the end of follow-up. The secondary outcomes were events during kidney transplantation and post-transplant de novo diseases adjusted by propensity score in log-binomial model. Results There were 1812 patients included in our cohort, among which 1209 (66.7%) and 603 (33.3%) recipients received pretransplant HD and PD, respectively. Recipients with chronic HD were generally older and male, had higher risks of developing post-transplant de novo ischaemic heart disease, tuberculosis and hepatitis C after adjustment. Pretransplant HD contributed to higher graft failure in the multivariate analysis (HR 1.38, p Conclusions Pretransplant HD contributed to higher risks of death-censored allograft failure after kidney transplantation when compared with PD.

Impact of the pretransplant dialysis modality on kidney transplantation outcomes: a nationwide cohort study

Kidney transplantation is the best option for the treatment of end-stage renal disease in terms of survival and quality of life. These results can be influenced by the pretransplant dialysis modality. The aim of this study was to evaluate whether the pretransplantation dialysis modality influences patient and allograft survival beyond 10 years and examine the potential risk factors associated with the outcomes. We conducted an observational, retrospective, single-center clinical study that included 236 patients [118 undergoing peritoneal dialysis (PD) and 118 undergoing hemodialysis (HD)] who proceeded to transplantation during the period December 1990–2002. Donor and recipient data were collected from our hospital’s clinical registries. The follow-up period extended to the patient’s death, the loss of the allograft, or loss to follow-up. The end date of the study was set at March 2012. In the multivariate analysis, the long-term patient survival rate was higher for the PD group than for the HD group [HR = 2.62 (1.01–6.8); p = 0.04]; however, the allograft survival rate was not significantly different between the two groups [HR = 0.68 (0.41–1.10); p = 0.12]. Pretransplantation dialysis modality is associated with long-term patient survival, with outcomes favoring peritoneal dialysis over hemodialysis. However, the pretransplant dialysis modality does not influence long-term graft loss risk.
