Abstract Background and Aims The burden of elderly patients initiating dialysis regimens is increasing around the world due to rising life expectancies. However, little is known regarding the results of elderly patients treated with peritoneal dialysis (PD). 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 This is a retrospective descriptive study performed in the PD unit in Monastir - Tunisia from 1990 till december 2017. All patients aged ≥ 65 years were included. The epidemiological and clinico-biological data as well as the complications were collected. Overall and technique survival rates were analyzed. Results Of the total 304 patients who began PD during the study period, 55 met our inclusion criteria. The prevalence of elderly patients was 18.1%. The mean age was 73 ± 5 years (65-86) with a male predominance (65.5%). Our patients were diabetic, hypertensive and cardiac in 45%, 64% and 33% respectively. Histories of hemodialysis necessity prior to PD use were present in 43.6 % of the patients. PD exchanges were performed by a member of the family in for 87.3% of cases and they often choose the CAPD (80%). Peritonitis rate was 17.92 patient-months. During the follow-up period, transfers to hemodialysis (15 patients) and death (39 patients) were the most common causes of withdrawal from PD. Frequent peritonitis, ultrafiltration failure warranted transfers to hemodialysis in 27% and 40% respectively. Causes of death were mostly not related to PD (87.2%) and they included cardiovascular events (28.2%), sepsis (20.5%) as well as neoplasma (15.4%). The mean patient survival time was 16.4 years versus 23.3 years in the other group. The survival rates were 96%, 93.5%, 86.9% and 76.6% at 1, 3, 5 and 10 years after peritoneal dialysis initiation, respectively. Advanced age (p 0.04) and occurrence of peritonitis (p 0.02) were predictors of mortality. The mean technique survival duration was 48.6±2.7 months. The technique survival rates were 78%, 62.6%, 53.5% and 41% at 1, 2, 3 and 4 years, respectively. Peritonitis was the primordial predictor of technique survival. Conclusion Mortality among elderly patients seems to be higher in our study. Infectious complications and cardiovascular events were the main causes of death. Advanced age and occurence of peritonitis represented the main predictive factors of mortality.

♦ Background Recently, more elderly patients who are independent or able to live at home with the support of family are opting for continuous ambulatory peritoneal dialysis (CAPD). At the end of 2005, the annual statistical survey conducted by the Japanese Society for Dialysis Therapy indicated that the mean age of patients at initiation of dialysis treatment is 66.2 years. Only 3.6% of the overall end-stage renal disease population were treated with CAPD, and this small number of elderly patients was treated with CAPD despite the many merits of peritoneal dialysis (PD) for the elderly. In the present study, we reviewed our experience with patients 65 years of age and older at the start of PD and the results from two multicenter studies on PD treatment in elderly patients in Japan. ♦ Patients and Methods Study 1: Of 313 PD patients at Okayama Saiseikai General Hospital between January 1991 and June 2006, 166 patients 65 years of age and older were studied. The characteristics of these elderly PD patients were reviewed to determine which elderly patients can continue PD for more than 5 years, and what the causes of death and the effects of icodextrin were in elderly PD patients. Study 2: A multicenter study of 421 patients introduced to PD from April 2000 to December 2004 in Japan was carried out by the Japanese Society for Elderly Patients on Peritoneal Dialysis to retrospectively analyze patient survival and technique survival and to find factors that have the potential to influence prognosis in these patients. Study 3: A review of the PD management and nursing-care insurance system (long-term care insurance) targeted patients 65 years of age and older who were initiated onto PD from January 2000 to June 2002 at 82 centers in Japan. The review found 765 patients under the age of 65 years (62.6%), and 458 patients 65 years of age and over (37.4%). Data on 409 elderly PD patients from 73 centers were analyzed. ♦ Results Study 1: In 166 elderly patients, 27 (16.3%; 18 women, 9 men) continued PD for more than 5 years at our hospital. The original disease was chronic glomerulonephritis in 21 patients, diabetic nephropathy in 2 patients, nephrosclerosis in 2 patients, and polycystic kidney disease in 2 patients. The causes of death in the elderly PD patients at our hospital were heart failure (20.3%), cerebrovascular disease (17.7%), myocardial infarction (15.2%), debilitation (12.7%), peritonitis (7.6%), and pneumonia (3.8%). We observed significant differences in ultrafiltration, body weight, sodium, chloride, red blood cells, and hematocrit after using icodextrin in 14 elderly PD patients. Also, use of icodextrin in the daytime helps the family supporting an elderly member on PD by reducing the number of exchanges. Study 2: The average age of 421 patients in 37 hospitals throughout Japan was 76.4 years. Women accounted for 41% of all patients. The average modified (exclusive of factors of aging) Charlson comorbidity index (CCI) was 3.7. The modified CCI was an important factor not only in patient survival but also in technique survival. Patient survival was significantly different for the three modified CCI groups (CCI < 3, 3 ≤ CCI < 5, 5 ≤ CCI). Factors that influenced patient survival included patient choice of modality, modified CCI, exchanges performed by family members, and age at the start of PD. Factors that influenced technique survival included patient choice of modality, modified CCI, and exchanges performed by family members. Age at the start of PD was not a significant factor influencing technique survival. Study 3: Most elderly PD patients were living with family; 7% were living alone. At the start of PD, 24% of elderly PD patients were covered by nursing-care insurance, including 11% of young elderly patients (65 – 74 years of age), 35% of old elderly patients (75 – 84 years of age), and 29% of very old elderly patients (85 years of age or older). Patients 75 years of age or older were covered by nursing-care insurance more frequently than were patients under 75 years of age. Nevertheless, at the start of dialysis, fewer than 10% of elderly patients were using nursing-care insurance for PD. ♦ Conclusions In elderly patients, PD has good outcomes, especially in nondiabetic patients, in patients with few comorbidities, and in patients managing PD by themselves. In introducing dialysis in elderly patients, PD should be the treatment of choice. A more secure support system should be established to allow the elderly to choose PD treatment.

Objective We have collected data on pediatric patients less than 16 years of age from the National Registry of Chronic Peritoneal Dialysis (PD). We present our experience with this population. Design The database details the patient numbers, age, outcome, cause of death, reason for terminating PD therapy, type of PD therapy, peritonitis, and catheter survival. Patients Of 807 patients, 70 patients (8.7%) were under 1 year of age, and 268 patients (33.2%) were under 6 years of age, clearly indicating that PD was the treatment of choice in young children. The duration on PD was 5 years or more in 200 patients (24.8%), which showed an increase in long-term PD patients from 11% in 1991. Patients on automated PD (APD) increased to 75% in 1997 from 9% in 1991. Results The outcomes for the total patient population of 807 as of the end of 1997 is: 253 patients (31.4%) were being successfully treated with PD, 87 patients (10.8%) died, 238 patients (29.5%) received a kidney transplant, and 121 (15.0%) were transferred to hemodialysis. The patient survival rate was 91% in 3 years and 86% in 5 years. The technique survival rate was 83% in 3 years and 71% in 5 years. The rate of peritonitis was 1 episode per 30 patient -months. The mean catheter duration was 2.25 years. Conclusion The patient and technique survival rates, the peritonitis rate, and the catheter survival improved recently. However, these data were worse in younger children (less than 6 years of age), indicating that extra-careful management is needed for this young age group.

ObjectivesWe aimed to evaluate clinical outcomes and identify the predictors of mortality in elderly patients undergoing continuous ambulatory peritoneal dialysis (CAPD).MethodsThis retrospective cohort study included all incident CAPD patients treated at our center from 2006 to 2009. Demographic and clinical data on initiation of CAPD and clinical events during the study period were collected. Survival probabilities were generated using the Kaplan–Meier method, and risk factors for mortality were evaluated using Cox proportional hazards models.ResultsOf 805 patients on CAPD, the elderly group (≥65 years; mean age: 71.3 ± 4.3 years) consisted of 148 patients, and the younger group (<65 years; mean age: 43.1 ± 12.2years) consisted of 657 patients. The 1-, 2-, 3-, and 5-year patient survival rates were 97%, 92%, 88%, and 73% for the younger group, and 79%, 67%, 56%, and 30% for elderly group. The patient survival rates were significantly lower for the elderly group than for the younger group ( p = 0.000). However, technique survival did not significantly differ between the groups ( p = 0.559). In the patients overall, the independent predictors of death were old age ( p = 0.003), diabetes ( p = 0.000), cardiovascular disease ( p = 0.006), lower hemoglobin ( p = 0.010), and lower serum albumin ( p = 0.024). Mortality in the elderly patients was associated with advanced age [relative risk (RR): 1.088; 95% confidence interval (CI): 1.027 to 1.153; p = 0.004], diabetes (RR: 2.064; 95% CI: 1.236 to 3.445; p = 0.006), and lower serum albumin (RR: 0.940; 95% CI: 0.897 to 0.985; p = 0.010).ConclusionsThe elderly patients on CAPD experienced technique survival comparable with that of younger patients, but their patient survival was lower. In elderly patients, mortality was determined predominantly by greater age, diabetes, and lower serum albumin. Our results indicate that chronic peritoneal dialysis is a viable dialysis option for elderly patients with end-stage renal disease. Better management of hypoalbuminemia and comorbid conditions might improve survival in elderly PD patients.

Objective Few data are available about elderly patients on peritoneal dialysis (PD). In the present study, we reviewed our experience with patients aged 70 years or more at the start of peritoneal dialysis (PD). Design This retrospective study was conducted at a single center in Japan. Patients and Methods Of 222 patients managed using PD at our hospital between 1991 and 2001 (including 219 cases of PD first), 150 patients were aged under 70 years and 72 patients were 70 years of age or older. For the two groups of patients, we determined clinical data, erythropoietin and PD prescriptions, reasons for selecting PD (elderly patients only), urine and ultrafiltration volumes, comprehensive functional assessment, quality of life (QOL), comorbidity, technique survival rate, and causes of death. Results Serum creatinine, serum β2-microglobulin, total dose of erythropoietin (EPO) needed to maintain hematocrit at 30%, number of continuous ambulatory peritoneal dialysis (CAPD) exchanges, and total volume of dialysis solution prescribed were significantly lower in the elderly patients as compared with patients aged under 70 years. The main reasons for starting PD in elderly patients at our hospital were advanced age (57%), patient's choice (25%), and cardiovascular complications (9%). Residual renal function was well maintained in CAPD patients aged 70 years or more as compared with patients aged under 70 years. Ultrafiltration volume was lower in the elderly CAPD patients. Scores on the Revised Hasegawa Dementia Scale, the Physical Self-Maintenance Scale, and the Instrumental Activities of Daily Living scale were significantly higher in CAPD patients than in hemodialysis patients. Subjective assessment using a linear analog scale showed a high QOL score in the elderly patients for overall feelings of well-being, mood, and anxiety. At the time of dialysis introduction, the major existing disorders in patients over 80 years of age were mostly cardiovascular disorders such as heart failure, myocardial infarction, serious arrhythmia, and cerebrovascular disease. The median technique survival in patients aged 70 years or more was 31.5 months. The main causes of death in elderly PD patients were heart failure (35.7%), peritonitis (14.3%), and cerebrovascular disease (11.9%). Conclusion Peritoneal dialysis should be considered the treatment method of choice when introducing dialysis in elderly patients.

Abstract Background and Aims The prevalence of obesity has increased over the past decade in patients with End Stage Kidney Disease (ESKD). Obesity at the initiation of peritoneal dialysis (PD) was reported to adversely affect clinical outcomes. However, there are few studies on the prognostic relevance of weight gain after PD. Method We reviewed the change in body weight of 954 consecutive PD patients from the initiation of dialysis to 2 years after they remained on PD. Clinical outcomes including patient survival, technique survival, and peritonitis rate in the subsequent two years were reviewed. Results The mean age was 60.3 ± 12.2 years; 535 patients (56.1%) were men and 504 (52.8%) had diabetes. After the first 2 years on PD, the average change in body weight was 1.2± 5.1 kg; their body weight was 63.0 ± 13.3 kg; body mass index (BMI) 24.4 ± 4.4 kg/m2. The patient survival rates in the subsequent two years were 64.9%, 75.0%, and 78.9% (log rank test, p = 0.008) for patients with weight loss ≥3 kg during the first 2 years of PD weight change between -3 and +3 kg, and weight gain ≥3 kg, respectively. The corresponding technique survival rates in the subsequent two years were 93.1%, 90.1%, 91.3%, respectively (p = 0.110), and the peritonitis rates were 0.7±1.5, 0.6±1.7, and 0.6±1.1 episodes per patient-year, respectively (p = 0.3). When the actual BMI after the first 2 years of PD was categorized into underweight, normal weight, marginal overweight, overweight, and obesity groups, the patient survival rates in the subsequent two years were 77.3%, 75.2%, 73.3%, 74.3%, and 75.9%, respectively (p= 0.005), and technique survival 98.0%, 91.9%, 88.0%, 92.8%, and 81.0%, respectively (p= 0.001). After adjusting for confounding clinical factors by multivariate Cox regression models, weight gain ≥ 3kg during the first 2 years of PD was an independent protective factor for technique failure (adjusted hazard ratio [AHR] 0.049; 95% confidence interval [CI] 0.004-0.554, p = 0.015), but was an adverse predictor of patient survival (AHR 2.338, 95%CI 1.149-4.757, p = 0.019). In contrast, weight loss ≥ 3kg during the first 2 years of PD did not predict subsequent patient or technique survival. Conclusion Weight gain during the first 2 years of PD confers a significant risk of subsequent mortality but appears to be associated with a lower risk of technique failure. The mechanism of this discordant risk prediction deserves further study.

BackgroundPeritoneal dialysis (PD) is developing rapidly in China, but because there are not enough well-trained PD doctors and nurses in more rural areas, this expansion is occurring mainly in larger cities. To address this imbalance, our center established a PD satellite center program across Guangdong Province, with the aim of extending the use and improving the quality of PD.MethodsSun Yat-sen University PD center is responsible for running the satellite program. The PD satellite centers are selected using specific criteria. The full-time PD physicians and nurses in the satellite centers accept a unified training program and treatment practices, and their clinical outcomes are carefully followed by our center.ResultsThe program began in January 2008, and there are now 12 PD centers from which 26 doctors and 32 nurses received PD training. Several hundred patients are now receiving PD through this program. The total number of PD patients treated by our center and the satellites increased to 1860 from 1010. The number treated in the satellite units increased to 1165 from 601. The annual dropout rate fell to 17.6% from 28.2%, and the average peritonitis incidence fell from 1 episode in 39.4 patient–months to 1 episode in 46.2 patient–months. The 1-year patient and technique survival rates increased to 84.2% from 82.0% and to 93% from 88.7% respectively.ConclusionsOur PD satellite center program is a good model for increasing the use and improving the quality of PD in rural areas. We plan to expand this program to other parts of southern China.

Background Peripheral artery disease (PAD) is highly prevalent among patients in end-stage renal disease. The ankle–brachial index (ABI) is believed to be highly correlated with the subclinical PAD of lower extremities but little is known about the associated risk factors and outcome for PAD and ABI in patients on peritoneal dialysis (PD). Methods We performed a cohort study of 153 patients from a single center receiving stable PD for more than 3 months. These patients were screened for subclinical PAD using the ABI measurement. The ABI was measured and a ratio of <0.9 was considered abnormal. Clinical outcomes included actuarial patient and technique survival in this study. Results 30 patients were classified into a subclinical PAD group. The prevalence of PAD (subclinical and overt) in our PD center was 19.61% (30/153). Advanced age, preexisting diabetes, preexisting cardiovascular and/or cerebrovascular disease (CVD), lower renal Kt/V urea, lower renal creatinine clearance (WCrCl), lower serum albumin level, and higher serum triglyceride level were risk factors for PAD in our PD center. Bivariate analysis showed that ABI was positively correlated with residual renal Kt/V urea and WCrCl, but was not correlated with peritoneal Kt/V urea and WCrCl. Patient and technique survival rates were significantly lower in the low ABI group than in the normal ABI group. Conclusions ABI is highly correlated with advanced age, preexisting diabetes, preexisting CVD, serum albumin, serum triglyceride, and residual renal clearance in PD patients. Also, lower ABI is independently associated with a high risk of patient mortality and PD technique failure.

Background There are no Taiwanese publications and only a few Asian publications on the long-term outcome of peritoneal dialysis (PD) patients. The aim of this study was to evaluate the outcome of PD patients in Taiwan during a 7-year follow-up period. Patients and Methods This study enrolled 67 patients (23 males, mean age 46.2 ± 14.5 years) on maintenance PD. We administered the Short-Form questionnaire on 30 September 1998 and recorded major events and outcomes until 30 September 2005. We compared differences in initial parameters between groups categorized by PD patient survival and PD technique survival. Causes of mortality and transfer to hemodialysis were determined. PD patient and PD technique survival rates were measured and risk factors for patient mortality and PD technique failure were analyzed. Results Those in patient survival or PD technique survival groups had lower mean age ( p < 0.001 and 0.018 respectively) and higher serum albumin level ( p = 0.015 and 0.041 respectively) compared to those that died or failed PD. The 7-year patient survival rate was 77% and the PD technique survival rate was 58%. The independent predictors for PD technique failure included lower Mental Component Summary scores [hazard ratio (HR) = 0.85, p = 0.031] and diabetes mellitus (HR = 4.63, p < 0.001), whereas lower serum albumin level (HR = 0.22, p = 0.031), lower Physical Component Summary scores (HR = 0.67, p = 0.047), and presence of diabetes mellitus (HR = 5.123, p = 0.009) were the independent predictors for patient mortality. Conclusion For our PD patients, both patient and technique survival rates are good. Better glycemic control, adequate nutrition, and enhancement of health-related quality of life are all of potential prognostic benefit.

BACKGROUND The pediatric peritoneal dialysis (PD) program in Cipto Mangunkusumo Hospital, Indonesia was started in 2014. However, there has been no published data on the patients’ outcome. This study was aimed to report the characteristics and outcomes of a continuous ambulatory peritoneal dialysis (CAPD) program for children. METHODS This retrospective study was conducted in Cipto Mangunkusumo Hospital as a national referral hospital. Data were collected from medical records of patients aged ≤18 years with end-stage renal disease who underwent CAPD in 2014–2019. The baseline characteristics, PD-related infection rate, as well as patient and technique survivals were analyzed. RESULTS Out of 60 patients who underwent CAPD, 36 (60%) were boys on the age range of 4 months–18 years. The mean follow-up duration was 12 (95% confidence interval [CI] = 9.4–15.3) months. The number of PD related infections increased along with the growing number of patients on CAPD. The peritonitis rate was 0.42 episodes per year at risk, and the most common etiology was alpha-hemolytic Streptococcus (5/24, [20.8%]). The 1- and 3-year technique survival rates were 60.3% (95% CI = 44.5–72.9) and 43.9% (95% CI = 23.2–62.9). The 1- and 3-year patient survival rates were 69.6% (95% CI = 52.5–81.5) and 58% (95% CI = 31.2–77.5). CONCLUSIONS In this unit, CAPD could be performed in children as young as 4 months of age. The peritonitis rate was relatively low which was likely caused by skin-derived microorganisms. Both technique survival and patient survival were also relatively low.
