Abstract
OBJECTIVES It remains unclear whether posttransplant outcomes differ according to the pretransplant dialysis modality (peritoneal dialysis vs hemodialysis). Our aim was to assess posttransplant outcomes in patients with different predialysis modalities. MATERIALS AND METHODS Two thousand two hundred fifty-eight kidney recipients following up in Hamed Alessa Organ transplant center in Kuwait were included and divided into two groups according to pre-transplant dialysis modality: Group 1: those who received hemodialysis (HD) and group 2: those with peritoneal dialysis (PD). Demographics, pretransplant and posttransplant comorbidities, and patient and graft outcomes were studied. RESULTS There were 1956 patients on hemodialysis, and 302 patients were on peritoneal dialysis. Most were male patients (1456 vs 802 female patients), with comparable mean age (P = .34). Chronic glomerulonephritis and diabetic nephropathy represented the most common original kidney disease before transplant (27.6% and 21.4%, respectively), with higher prevalence of glomerulonephritis in group 1 and diabetic nephropathy in group 2 (P = .001). The 2 groups were comparable with regard to immunosuppression (induction and maintenance) (P > .05). Posttransplant diabetes and hypertension were significantly higher in the hemodialysis group (P = .004 and P = 003, respectively). There was no significant difference between the 2 groups with regard to the graft outcome (P = .86). However, patient survival was significantly higher in the hemodialysis group (81.2% vs 64.4%). CONCLUSIONS Compared with peritoneal dialysis, pretransplant hemodialysis is associated with better posttransplant patient survival despite no difference in the graft outcome. Diabetes-related complications could be attributed to such outcomes.

Abstract
BACKGROUND The impact of dialysis modality before kidney transplantation (hemodialysis or peritoneal dialysis) on outcomes is not clear. In this study we retrospectively analyzed the impact of dialysis modality on posttransplant follow-up. METHODS To minimize donor bias, a paired kidney analysis was applied. One hundred thirty-three pairs of peritoneal dialysis (PD) and hemodialysis (HD) patients were transplanted at our center between 1994 and 2016. Those who received kidneys from the same donor were included in the study. HD patients were significantly older (44 vs 48 years), but the Charlson Comorbidity Index was similar (3.12 vs 3.46) in both groups. The groups did not differ significantly with respect to immunosuppressive protocols and number of mismatches (2.96 vs 2.95). RESULTS One-year patient (98% vs 96%) and graft (90% vs 93%) survival was similar in the PD and HD patient groups. The Kaplan-Meier curves of the patients and graft survival did not differ significantly. Delayed graft function (DGF) and acute rejection (AR) occurred significantly more often in the HD recipients. Graft vessel thrombosis resulting in graft loss occurred in 9 PD (6.7%) and 4 HD (3%) patients (P > .05). Serum creatinine concentration and estimated glomerular filtration rate (using the Modification of Diet in Renal Disease guidelines) showed no difference at 1 month, 1 year, and at final visit. On multivariate analysis, factors significantly associated with graft loss were graft vessel thrombosis, DGF, and graft function 1 month after transplantation. On univariate analysis, age, coronary heart disease, and graft loss were associated with death. Among these factors, only coronary heart disease (model 1) and graft loss were significant predictors of death on multivariate analysis. CONCLUSION The long-term outcome for renal transplantation is similar in patients with PD and HD. These groups differ in some aspects, however, such as susceptibility to vascular thrombosis in PD patients, and to DGF and AR in HD patients.

Abstract
Previous studies have reported contradictory results regarding the effect of pre-transplant dialysis modality on the outcomes after kidney transplantation (KT). To minimize the confounding effect of donor-related variables, we performed a donor-matched retrospective comparison of 160 patients that received only one modality of pre-transplant dialysis (peritoneal dialysis [PD] and hemodialysis [HD] in 80 patients each) and that subsequently underwent KT at our center between January 1990 and December 2007. Cox regression models were used to evaluate the association between pre-transplant dialysis modality and primary study outcomes (death-censored graft survival and patient survival). To control for imbalances in recipient-related baseline characteristics, we performed additional adjustments for the propensity score (PS) for receiving pre-transplant PD (versus HD). There were no significant differences according to pre-transplant dialysis modality in death-censored graft survival (PS-adjusted hazard ratio [aHR]: 0.65; 95% confidence interval [95% CI]: 0.25-1.68) or patient survival (aHR: 0.58; 95% CI: 0.13-2.68). There were no differences in 10-year graft function or in the incidence of post-transplant complications either, except for a higher risk of lymphocele in patients undergoing PD (odds ratio: 4.31; 95% CI: 1.15-16.21). In conclusion, pre-transplant dialysis modality in KT recipients does not impact short- or long-term graft outcomes or patient survival.

Abstract
BACKGROUND Previous studies have found inconsistent associations between pre-transplant dialysis modality and subsequent post-transplant survival. We aimed to examine this relationship using the instrumental variable method and to compare the results with standard Cox regression. METHODS We included 29 088 patients (age >20 years) from 16 European national or regional renal registries who received a first kidney transplant between 1 January 1999 and 31 December 2008 and were on dialysis before transplantation for a period between 90 days and 10 years. Standard multivariable Cox regression examined the association of individually assigned pre-transplant dialysis modality with post-transplant patient and graft survival. To decrease confounding-by-indication through unmeasured factors, we applied the instrumental variable method that used the case-mix adjusted centre percentage of peritoneal dialysis (PD) as predictor variable. RESULTS Standard analyses adjusted for age, sex, primary renal disease, donor type, duration of dialysis, year of transplantation and country suggested that PD before transplantation was associated with better patient [hazard ratio, HR (95% CI) = 0.83 (0.76-0.91)] and graft survival (HR (95% CI) 0.90 (0.84-0.96)) when compared with haemodialysis (HD). In contrast, the instrumental variable analysis showed that a 10% increase in the case-mix adjusted centre percentage of patients on PD was neither associated with post-transplant patient survival [HR (95% CI = 1.00 (0.97-1.04)] nor with graft survival [HR (95% CI) = 1.01 (0.98-1.04)]. CONCLUSIONS The instrumental variable method failed to confirm the associations found in standard Cox regression between pre-transplant dialysis modality and patient and graft survival after transplantation. The lack of association in instrumental variable analysis may be due to better control of residual confounding.

Abstract
Background. In previous reports with a majority of Caucasian patients, peritoneal dialysis (PD) before kidney transplantation has been associated with poor outcomes and higher rates of graft thrombosis and infectious complications than hemodialysis (HD). We report our experience on the outcomes of prerenal transplant peritoneal dialysis in predominantly (73%) African American patient population.
Methods. A retrospective data analysis of 401 kidney transplants performed at our center from 2000 to 2006 was performed. Adult recipients with at least three months of pretransplant HD or PD were included.
Results. There were 339 patients on HD and 62 patients on PD. There was no difference in graft (P = 0.51) and patient survival (P = 0.52) at 1, 3, and 5-years. Patients on HD were more likely to experience delayed graft function than PD (38.8% versus 17.7%, P < 0.005). There was no difference in the incidence of vascular thrombosis or posttransplant infectious complications. When only the African American patients in the two groups were compared, there were no differences in graft or patient survival.
Conclusions. Pretransplant peritoneal dialysis is associated with excellent patient and renal allograft outcomes in African Americans and does not predispose them to an increased risk of infectious or thrombotic complications.

Abstract
Encapsulating peritoneal sclerosis (EPS) is a severe complication of peritoneal dialysis (PD) and may present after kidney transplantation, a condition known as posttransplantation EPS. The prevalence and impact of posttransplantation EPS on survival after kidney transplantation is unknown. From January 1, 1996 until July 1, 2007, 1241 PD patients were transplanted. Thirty-eight cases of posttransplantation EPS (3%) were identified from the Dutch multicenter EPS study. In EPS patients the mean pretransplant dialysis duration was longer than in the controls (71.4 ± 37.5 months vs. 34.7 ± 25.5, p < 0.0001). The majority of EPS cases were observed within the first 2 years after transplantation, but some cases appeared many years after transplantation. Two hundred and one (16.2%) patients died after transplantation, of which 17 were EPS patients. After infection (23.9%), cardiovascular disease (21.9%) and malignancy (10.9%), EPS (8.5%) was the fourth known cause of death after transplantation. Kaplan-Meier analysis showed a significant decreased survival for transplanted patients with posttransplantation EPS compared to transplanted patients without EPS. In conclusion, posttransplantation EPS is rare but carries a high mortality. A prolonged clinical vigilance and a high index of suspicion for the diagnosis are warranted, specifically in PD patients with a relatively long cumulative pretransplant duration of PD.

Abstract
Several studies have yielded conflicting results regarding morbidity and mortality in peritoneal dialysis (PD) and hemodialysis (HD) patients. We performed a retrospective analysis in end-stage renal disease (ESRD) patients in our department, who were equally distributed between HD and PD, in order to compare 5-year survival probabilities and hospitalization rates in the two modalities. Of the total 94 new ESRD patients who initiated dialysis in our department from January 1995 to December 2000, 48 were allocated to PD and 46 to HD. All patients were followed up for five years. There were no significant differences regarding demographics and serious co-morbidities upon dialysis initiation between HD and PD patients. Unadjusted 5-year survival probability in as-treated analysis was higher in PD patients (0.79 vs 0.6, p=0.04), whereas there was no significant difference in intent-to-treat analysis between HD and PD patients (p=0.5). Hospitalization rates were similar in both modalities. Despite the small number of patients included in our study, it seems that when HD and PD are both available in one department they have equivalent results regarding morbidity and mortality rates. Therefore we suggest that, when possible, PD and HD should be equally offered to all ESRD patients.
