This study summarizes the overall experience of the first six years of CAPD treatment at one centre, during which time all patients (n = 124) were selected, trained, and treated in a uniform way. Patient selection was largely influenced by a high transplantation activity. The patients had a high mean age, 54 years at start of CAPD, and there was a high proportion of diabetics, 26%. Patient survival was 81% after two years and 60% after four years for all patients, and 100% after four years for non-diabetic patients < 50 years of age. Patient and technique survival was significantly superior in younger non-diabetics than in diabetics and in non-diabetics ≥ 60 years. Thirty-nine percent of transfers to other forms of dialysis were due to peritonitis. The main reason for a high early discontinuation rate was transplantation. The mean treatment time in hospital was 27.7 d per patient year, one-third of which was attributable to peritonitis. The risk of developing peritonitis within the first year on CAPD was 55%. During CAPD, serum urea remained unchanged, serum potassium, creatinine, and uric acid levels increased, and serum albumin levels decreased. These findings suggest that patients being treated with four 2 L exchanges Id, may not be sufficiently dialyzed as the residual renal function deteriorates, thereby increasing the risk of anorexia and subsequent malnutrition.

Technique Failure

BackgroundPeritoneal dialysis (PD) technique failure is high compared to hemodialysis (HD). There is a lack of data on the impact of duration of PD treatment on technique survival and on whether there is a difference in risk factors with respect to early and late failure. The aim of this study was to clarify these issues by performing a time-dependent analysis of PD technique and patient survival in a large cohort of incident PD patients.MethodsWe analyzed 709 incident PD patients participating in the Netherlands Cooperative Study on the Adequacy of Dialysis (NECOSAD), who started their treatment between 1997 and 2007. We compared technique and patient survival on PD in 4 periods of follow-up: within the first 3 months, and after 3 – 12 months, 12 – 24 months, and 24 – 36 months of treatment. Cox proportional hazards model was used to analyze survival on PD and technique failure. Risk factors were also identified by comparing patients that were transferred to HD with those that remained on PD. Incidence rates for every cause of dropout for each period of follow-up were calculated to establish their trends with respect to PD treatment duration.ResultsThere was a significant increase in transplantation rate after the first year of treatment. The rate of switching to HD was highest during the first 3 months and decreased afterward. One-, 2- and 3-year technique survival was 87%, 76%, and 66%, respectively. Age, diabetes, and cardiovascular disease appeared to be risk factors for death on PD or switch to HD: a 1-year increase in age was associated with a relative risk (RR) of PD failure of 1.04 [95% confidence interval (CI) 1.003 – 1.06]; for diabetes, RR of stopping PD after 3 months of treatment increased from 1.8 (95% CI 1.1 – 3) during the first year to 2.2 (95% CI 1.3 – 4) after the second year; cardiovascular disease had a major impact in the earliest period (RR 2.5, 95% CI 1.2 – 5) and had a stable influence further on (RR 2, 95% CI 1.1 – 3.5). Loss of 1 mL/minute residual glomerular filtration rate (rGFR) appeared to be a significant predictor of PD failure after 3 months of treatment, but within the first 2 years, RR was 1.1 (95% CI 1.04 – 1.25).ConclusionsIn The Netherlands, transplantation is a main reason to stop PD treatment. The incidence of PD technique failure is at its highest during the earliest months after treatment initiation and decreases later due to fewer catheter and abdominal complications as well as less influence of psychosocial factors. Risk factors for PD discontinuation are those responsible for patient survival: age, cardiovascular disease, diabetes, and rGFR.

Abstract Background and Aims Peritoneal dialysis (PD) is generally associated with a good survival rate and with great preservation of residual renal function (RRF). The various causes of technique failure are responsible for the relative short time staying in PD. Objectives: This study aimed to analyze the outcome and factors correlated with maintenance peritoneal dialysis (PD) to guide for improving prognosis. Method In a retrospective way we examined our PD-cohort concerning mortality, technique survival, peritonitis rate, and other complications. Results From 2005 to 2019 the number of PD patients who have been treated in PD program for more than 3 months was around 199 patient, 29.1% diabetics, mean age 53.3±15.03 years old and meantime in therapy 32.39± 27.34 months. The PD was seen as an alternative for younger patients in the transplant list and elderly patients with comorbidity. Around 7.5% of the PD patients were transplanted and 8.5 % of patients were transferred from HD due to vascular access failure. Around 88.9% of patients were on PD for more than 1 year, 37.7% from 3 up to 5 years and 19.8% percent of the patients have stayed on PD for more than 5 years. Cardiovascular mortality was the main cause of mortality with 53% of the cases. Higher comorbidity index, lower albumin levels, and lower residual renal function were the main risk factors for lower survival. The technical survival of patients was 92.3% during the first year, 79.5% and 69.6% in the second and the fifth year, respectively. There was not found a difference in technical survival between diabetics and nondiabetics patients. Ultrafiltration failure followed by peritonitis was the main reason for transfer patients with more than 24 months in therapy in hemodialysis probably linked with the no availability of icodextrin. Peritonitis rate was 1:41 patient months. Conclusion PD program in our center is organized based in the concept of integrated care in RRT. The outcome of our patients was at least comparable to those reported by larger registries Although we have done good progress in the prevention of infection the nonavailability of icodextrin is an important factor for a technical failure. RRF is an important factor and we need to be more focused to maintain it longer in the future.

The objective of this study was to evaluate the association of peritoneal membrane transport with technique and patient survival. In the Canada-USA prospective cohort study of adequacy of continuous ambulatory peritoneal dialysis (CAPD), a peritoneal equilibrium test (PET) was performed approximately 1 mo after initiation of dialysis; patients were defined as high (H), high average (HA), low average (LA), and low (L) transporters. The Cox proportional hazards method evaluated the association of technique and patient survival with independent variables (demographic and clinical variables, nutrition, adequacy, and transport status). Among 606 patients evaluated by PET, there were 41 L, 192 LA, 280 HA, and 93 H. The 2-yr technique survival probabilities were 94, 76, 72, and 68% for L, LA, HA, and H, respectively (P = 0.04). The 2-yr patient survival probabilities were 91, 80, 72, and 71% for L, LA, HA, and H, respectively (P = 0.11). The 2-yr probabilities of both patient and technique survival were 86, 61, 52, and 48% for L, LA, HA, and H, respectively (P = 0.006). The relative risk of either technique failure or death, compared to L, was 2.54 for LA, 3.39 for HA, and 4.00 for H. The mean drain volumes (liters) in the PET were 2.53, 2.45, 2.33, and 2.16 for L, LA, HA, and H, respectively (P < 0.001). After 1 mo CAPD treatment, the mean 24-h drain volumes (liters) were 9.38, 8.93, 8.59, and 8.22 for L, LA, HA, and H, respectively (P < 0.001); the mean 24-h peritoneal albumin losses (g) were 3.1, 3.9, 4.3, and 5.6 for L, LA, HA, and H, respectively (P < 0.001). The mean serum albumin values (g/L) were 37.8, 36.2, 33.8, and 32.8 for L, LA, HA, and H, respectively (P < 0.001). Among CAPD patients, higher peritoneal transport is associated with increased risk of either technique failure or death. The decreased drain volume, increased albumin loss, and decreased serum albumin concentration suggest volume overload and malnutrition as mechanisms. Use of nocturnal cycling peritoneal dialysis should be considered in H and HA transporters.

The Mean

During the first four years of the CAPD programs in Toronto, 409 patients completed CAPD training; of these 64 (15.7%) were diahetics. The mean age of the diabetics was 46.7 and of the non-diabetics 51.4 years. One and two-year survival rates were not significantly different between the two groups (93%-82% for the non-diabetics and 90%-72% for the diabetics}. The main cause of death was cardiovascular events, in both groups. During the first year on CAPD, diabetics were transplanted at a higher rate than non-diabetics (20% vs. 9%). The overall technique success rate, the rate of transfer to an alternative dialysis modality and the incidence of peritonitis were similar in the two groups. At least in the short -term, diabetics do well on CAPD. It is suggested that CAPD may be the dialysis modality of choice in diabetics with ESRD.

Abstract Background and Aims Diabetes in recent years is climbing up as the number one cause of chronic kidney disease (CKD). Clinical statistics suggest that Diabetics on peritoneal dialysis (PD) tend to have a poorer prognosis than others. Thus, the aim of this study is to determine the clinical outcomes and to evaluate the survival rates as well as the predictors of mortality among this group. Method It‘s a retrospective study carried out in the nephrology Department of Fattouma Bourguiba Hospital (Monastir, Tunisia) from 1990 to 2017 including 304 PD patients. We compared two groups: diabetic and non diabetic patients in term of survival and factors in correlation. Results A total of 110 diabetic versus 194 non diabetic patients were reported. The mean age of diabetic group was 55.14 ± 15 years with a sex ratio 2.33 (men/women). In addition to diabetes, comorbid diseases included hypertension (47.3%) and cardiopathy (32.7%). The mean Charlson score of diabetic group was 5.22±1.5 versus 2.72±1.23 in the other group. A total of 62.7% (n=69) of the patients performed PD with the help of another person mostly a member of the family. The PD modality often used was CAPD (71%). Only six patients made a compulsory choice to begin PD due to vascular access while sixty diabetics chose PD to maintain autonomy (54.5%). During the follow-up period, transfers to hemodialysis (40.9%) and death (53.6%) were the most common cause of withdrawal from PD. In total, 45 patients were transferred to hemodialysis because of infectious complications (31%), Ultrafiltration failure (31%), catheter dysfunction (27%), and psychological intolerance (11%). The death was unrelated to PD in 83% of cases mostly due to considerable burden of cardiovascular events (23 patients). The median survival of the diabetic patients was 15.8 years versus 20.8 years in non diabetic ones with significant difference between the 2 groups (p=0.0001). Diabetes was associated with worse prognosis (OR:147, p=0.0001). The median survival adjusted to the diabetes group was 180 months. Kaplan–Meier analysis showed that diabetes was associated with a significant increase in mortality (p=0.006). Global median survival of the technique was estimated to 68 months (95%, IC [47 ,90]), and it was correlated to the presence or the absence of diabetes. In fact, the technique survival among diabetic patients was estimated to 80% after 12 years and 25% after 20 years whereas, in the other group it approaches 90% and 35% respectively. Conclusion This study confirms the pejorative impact of diabetes in the technique and patient survival in DP. So, it stresses the importance of organizing appropriate care upstream to prevent the development of cardiovascular morbidities and infectious complications in DP.

Objective There is controversy whether increasing peritoneal clearance effectively substitutes for declining residual renal function. We studied the impact of renal and peritoneal clearances on outcome, controlling for comorbidity. Design Registry database. Settings Four dialysis centers. Patients Incident peritoneal dialysis patients. Methods Data were collected prospectively on 90 incident patients between 1991 and 1999. At the end of their first year on peritoneal dialysis, patients were divided into groups based on the first year's clearance results: group 1 ( n = 62) had weekly Kt/V greater than or equal to 2.0 and creatinine clearance (CCr/1.73 m2) greater than or equal to 60 L throughout the first year; group 2 ( n = 28) fell below these targets due to loss of residual renal function and then reached targets due to prescription change. Main Outcome Measures Patient and technique survival. Results Both groups were similar in baseline characteristics except age (57 years vs 49 years, p = 0.02) and initial albumin (34.4 g/L vs 37.5 g/L, p = 0.001). One-year patient survival after grouping was similar in both groups (86.3% vs 80.9%, p = 0.72). Cox proportional hazard model, controlling for comorbidity, did not show “group” to be a significant predictor of outcome ( p = 0.96). One-year technique survival after grouping was similar in both groups (77.3% vs 83.2%, log rank p = 0.89). For technique failure, Cox proportional hazard model showed peritonitis ( p = 0.004) to be the only significant predictor of worse outcome. Conclusions Peritoneal dialysis patients with improved clearances due to prescription changes had survival comparable to patients who never fell below target. This suggests that loss of residual renal function may be replaced by increasing peritoneal dialysis clearance. A large multicenter trial to study this important question further is needed.

Abstract. Dialysis adequacy has a major impact on the outcome of continuous ambulatory peritoneal dialysis (CAPD) patients. However, most studies on peritoneal dialysis adequacy have focused on patients with significant residual renal function. The present study examined the effect of dialysis adequacy on anuric CAPD patients. A single-center prospective observational study on 140 anuric CAPD patients was performed. These patients were followed for 22.0 ± 11.9 mo. Dialysis adequacy and nutritional indices, including Kt/V, creatinine clearance (CCr), protein equivalent nitrogen appearance, percentage of lean body mass, and serum albumin level were monitored. Clinical outcomes included actuarial patient survival, technique survival, and duration of hospitalization. In the study population, 64 were male, 36 (25.7%) were diabetic, and 59 (42.1%) were treated with 6 L exchanges per day. The body weight was 59.2 ± 10.2 kg. Average Kt/V was 1.72 ± 0.31, and CCr was 43.7 ± 11.5 L/wk per 1.73m2. Two-yr patient survival was 68.8%, and technique survival was 61.4%. Multivariate analysis showed that DM, duration of dialysis before enrollment, serum albumin, and index of dialysis adequacy (Kt/V or CCr) were independent factors of both patient survival and technique survival. It was estimated that for two patients who differed only in weekly Kt/V, a 0.1 higher value was associated with a 6% decrease in the RR of death (P < 0.05; 95% confidence interval, 0.92 to 0.99). Serum albumin and CCr were the only independent factors that predicted hospitalization. It was found that even when there is no residual renal function, higher dialysis dosage is associated with better actuarial patient survival, better technique survival, and shorter hospitalization. Dialysis adequacy has a significant impact on the clinical outcome of CAPD patients, and the beneficial effect is preserved in anuric patients as well as in an ethnic group that has a low overall mortality.

Independent Effects

Objective Previous studies show that peritoneal Kt/V is an independent predictor of survival in anuric patients receiving continuous ambulatory peritoneal dialysis (CAPD). We studied whether peritoneal Kt/V has the same effect in CAPD patients with residual renal function. Design Observational cohort study. Setting Single dialysis center in a university teaching hospital. Patients New and prevalent CAPD patients. Methods We examined the 5-year follow-up results of our prospective study previously reported ( Kidney Int 2000; 58:400–7). A total of 270 CAPD patients were followed for up to 6 years. Dialysis adequacy indices, residual renal function, and nutritional data were monitored. Outcome Measures Primary outcomes included mortality and technique failure. Peritoneal Kt/V rather than total Kt/V was used for multivariate survival analysis. Results Average duration of follow-up was 35.1 ± 22.0 months. Average peritoneal Kt/V throughout the study was 1.59 ± 0.37; median residual glomerular filtration rate (GFR) 0.82 mL/minute. Five-year actuarial patient survival was 41.5%, and technique survival was 23.1%. Multivariate analysis showed that sex, age, duration of dialysis, presence of diabetes, serum albumin, dialysate-to-plasma creatinine ratio at 24 hours, peritoneal Kt/V, residual GFR, and normalized protein nitrogen appearance were independent factors of both actuarial patient survival and technique survival. For every 0.1 unit higher peritoneal Kt/V, relative mortality risk was 0.94 (95% CI 0.89 – 0.99, p = 0.03). When prevalent and new CAPD cases were analyzed separately, peritoneal Kt/V predicted survival only for prevalent CAPD patients. Conclusion We conclude that, in prevalent CAPD patients with relatively low levels of peritoneal clearance and residual renal function, a higher peritoneal Kt/V is associated with better survival. Peritoneal clearance below 1.6 – 1.7 likely has a major detrimental effect on the clinical outcome of CAPD patients with little residual renal function.

Background: This retrospective cohort study compared patient survival and technique survival between patients on continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) using recent data at a single tertiary medical center in Taiwan. Methods: From medical records, we identified incident 459 CAPD patients and 266 APD patients on dialysis for at least 90 days and aged more than 18 years to estimate mortality and technique failure rates, and related hazard ratio (HR) and 95% confidence interval (CI) from 2007 to 2018. Results: There were more women (52.3%) in the CAPD group, whereas patients in the APD group were younger. Compared to CAPD patients, APD patients had a lower mortality rate (2.83 vs. 5.79 per 100 person-years) with an adjusted HR of 0.69 (95% CI = 0.47–1.02), and a lower technique failure rate (9.70 vs. 17.52 per 100 person-years) with an adjusted HR of 0.65 (95% CI = 0.51–0.83). Further subgroup analyses revealed that, compared to CAPD, APD was associated with a significant lower risk of technique failure in male patients, patients aged 50–65 years, diabetic patients, patients without cardiovascular disease (CVD), patients with higher peritoneal permeability, or patients initiating PD in an earlier era. Conclusions: The mortality risk was not significant between CAPD and APD patients. APD is associated with a lower risk of technique failure than CAPD, particularly for male patients, and patients aged 50–65 years, with diabetes, without CVD, with high or high average peritoneal permeability, or initiating PD in an earlier era.
