Introduction This study was carried out to examine whether or not elderly patients on peritoneal dialysis (PD) had an increased risk of peritonitis. Methods This was a retrospective cohort study based on data from the French Language Peritoneal Dialysis Registry. We analyzed 8,396 incident patients starting PD between January 2003 and December 2010. The end of the observation period was 31 December 2012. Patients were separated into 2 age groups: up to 75 and over of 75 years old. Results Among 8,396 patients starting dialysis there were 3,173 patients older than 75. When using a Cox model, no association was found between age greater than 75 years and increased risk of peritonitis (hazard ratio [HR]: 0.97 [0.88 – 1.07]). Diabetes (HR: 1.14 [1.01 – 1.28] and continuous ambulatory PD (HR: 1.13 [1.04 – 1.23]) were significantly associated with a higher risk of peritoneal infection whereas nurse-assisted PD was associated with a lower risk of peritonitis (HR: 0.85 [0.78 – 0.94]. In the analysis restricted to the 3,840 self-care PD patients, there was no association between age older than 75 years and risk of peritonitis. Conclusion The risk of peritonitis is not increased in elderly patients on PD in a country where assisted PD is available.

Assisted Peritoneal Dialysis

Background: Patients on peritoneal dialysis (PD) can be assisted by a nurse or a family member and treated either by automated PD (APD) or continuous ambulatory PD (CAPD). The aim of this study was to evaluate the effect of PD modality and type of assistance on the risk of transfer to haemodialysis (HD) and on the peritonitis risk in assisted PD patients. Method: This was a retrospective study based on data from the French Language PD Registry. All adults starting assisted PD in France between 2006 and 2015 were included. Events of interest were transfer to HD, peritonitis and death. Cox regression models were used for statistical analysis. Results: Among the 12,144 incident patients who started PD in France during the study period, 6,167 were assisted. There were 5,060 nurse-assisted and 1,095 family-assisted PD patients. Overall, 5,171 were treated by CAPD and 996 by APD. In multivariate analysis, CAPD, compared to APD, was not associated with the risk of transfer to HD (cause specific hazard ratios [cs-HR] 0.96 [95% CI 0.84–1.09]). Patients on nurse-assisted PD had a lower risk of transfer to HD than family assisted PD patients (cs-HR 0.85 [95% CI 0.75–0.97]). Neither PD modality nor type of assistance were associated with peritonitis risk. Conclusions: In assisted PD, technique survival was not associated with PD modality. Nurse-assisted patients had a lower risk of transfer to HD than family assisted patients. Peritonitis risk was not influenced either by PD modality, or by type of assistance. Both APD and CAPD should be offered to assisted-PD patients.

IntroductionThis study was carried out to investigate the center effect on the risk of peritoneal dialysis (PD) failure within the first 6 months of therapy using a multilevel approach.MethodsThis was a retrospective cohort study based on data from the French Language Peritoneal Dialysis Registry. We analyzed 5,406 incident patients starting PD between January 2008 and December 2012 in 128 PD centers. The end of the observation period was December 31, 2013.ResultsOf the 5,406 patients, 415 stopped PD within the first 6 months. There was a significant heterogeneity between centers (variance of the random effect: 0.10). Only 3% of the variance of the event of interest was attributable to differences between centers. At the individual level, only treatment before PD (odds ratio [OR]: 1.93 for hemodialysis and OR: 2.29 for renal transplantation) and underlying nephropathy ( p < 0.01) were associated with early PD failure. At the center level, only center experience was associated (OR: 0.78) with the risk of PD failure. Center effect accounted for 52% of the disparities between centers.ConclusionCenter effect on early PD failure is significant. Center experience is associated with a lower risk of transfer to hemodialysis.

Assisted Peritoneal Dialysis

End-stage renal disease (ESRD) is common in the elderly population, and renal replacement therapy (RRT) is often required. However, in this particular subgroup of patients, the choice between hemodialysis (HD) and peritoneal dialysis (PD) is often not an easy decision to make. Published literature has adequately demonstrated that PD prevalence is significantly less than HD across all patient age groups despite several advantages. We also know that elderly patients are less likely to complete a PD assessment, due to both medical and social barriers. Additionally, elderly patients are often reluctant to go ahead with PD despite being eligible PD candidates, mainly due to the fear of performing self-therapy. Recently, many new assisted PD (asPD) programs have cropped up in several countries. The main aim of these programs is to overcome barriers to PD and to promote PD utilization among elderly and non-self-sufficient patients. Although asPD has proven to be associated with good clinical results, there still remain concerns about its greater use. In this review, we will first describe an ideal asPD model and then enumerate examples of strategies and outcomes associated with successful asPD programs worldwide.

ObjectivesTo characterise trends in self-poisoning and psychotropic medicine use in young Australians.DesignPopulation-based retrospective cohort study.SettingCalls taken by the New South Wales and Victorian Poisons Information Centres (2006–2016, accounting for 70% of Australian poisoning calls); medicine dispensings in the 10% sample of Australian Pharmaceutical Benefits Scheme data (July 2012 to June 2016).ParticipantsPeople aged 5–19 years.Main outcome measuresYearly trends in intentional poisoning exposure calls, substances taken in intentional poisonings, a prevalence of psychotropic use (dispensing of antidepressants, antipsychotics, benzodiazepines and medicines for attention deficit hyperactivity disorder (ADHD)).ResultsThere were 33 501 intentional poisonings in people aged 5–19 years, with an increase of 8.39% per year (95% CI 6.08% to 10.74%, p<0.0001), with a 98% increase overall, 2006–2016. This effect was driven by increased poisonings in those born after 1997, suggesting a birth cohort effect. Females outnumbered males 3:1. Substances most commonly taken in self-poisonings were paracetamol, ibuprofen, fluoxetine, ethanol, quetiapine, paracetamol/opioid combinations, sertraline and escitalopram. Psychotropic dispensing also increased, with selective serotonin reuptake inhibitors (SSRIs) increasing 40% and 35% July 2012 to June 2016 in those aged 5–14 and 15–19, respectively. Fluoxetine was the most dispensed SSRI. Antipsychotics increased by 13% and 10%, while ADHD medication dispensing increased by 16% and 10%, in those aged 5–14 and 15–19, respectively. Conversely, dispensing of benzodiazepines to these age groups decreased by 4% and 5%, respectively.ConclusionsOur results signal a generation that is increasingly engaging in self-harm and is increasingly prescribed psychotropic medications. These findings indicate growing mental distress in this cohort. Since people who self-harm are at increased risk of suicide later in life, these results may foretell future increases in suicide rates in Australia.

Abstract Context: GH deficiency is common in childhood cancer survivors. In a previous report, although we did not find an increase in the risk of disease recurrence in survivors treated with GH, GH-treated survivors did have an increased risk of developing a second neoplasm (SN) (rate ratio, 3.21). Objective: In this analysis, we have reassessed the risk of GH-treated survivors developing an SN after an additional 32 months of follow-up. Design and Setting: We conducted a retrospective cohort multicenter study. Patients: Among a total of 14,108 survivors who were enrolled in the Childhood Cancer Survivor Study, a retrospective cohort of 5-yr survivors of childhood cancer, we identified 361 who were treated with GH. Main Outcome: We assessed the risk of developing an SN. Results: During the extended follow-up, five new SN developed in survivors treated with GH, for a total of 20 SN, all solid tumors. Using a time-dependent Cox model, the rate ratio of GH-treated survivors developing an SN, compared with non-GH-treated survivors, was 2.15 (95% confidence interval, 1.3–3.5; P &lt; 0.002). Meningiomas were the most common SN (n = 9) among the GH-treated group. Conclusion: Although cancer survivors treated with GH appear to have an increased risk of developing SN compared with survivors not so treated, the elevation of risk due to GH use appears to diminish with increasing length of follow-up. Continued surveillance is essential.

Abstract Abstract 3802 Background and Aim: The impact of the CA on prognosis and transformation into acute myeloid leukemia among pts with low and int-1 risk MDS is not known. The aims of the study were to assess the impact of CA on the natural history of pts with lower risk MDS and to identify factors associated with its development. Methods: We reviewed 721 pts clinical records of low and intermediate risk MDS pts from 2000–2010 and conducted a retrospective analysis of all pts with at least two consecutive cytogenetic analysis (365 patients, 51%). The acquisition of CA was defined by structural change or gain in at least 2 metaphases and loss in 3 metaphases, or otherwise confirmed by FISH. Cox proportional hazards regression models were fit to assess the association between transformation-free survival (TFS) or overall survival (OS) and pt characteristics. The acquisition of CA was fitted in the Cox model as a time-dependent covariate. The association between the acquisition of CA and pt characteristics was assessed through univariate and multiple logistic regression models. Results: CA was detected in 107 pts (29%) after a median follow-up of 34 months (mos). CA was observed in a median number of 4 metaphases (range, 2–30). At diagnosis, 21% and 79% of pts who acquired CA were low-and int-1risk MDS; 50% were diploid, 22% harbored chromosome 5 /7 abnormalities. At the time of acquisition of CA, the median percentage of bone marrow blasts was 4% (range, 0% to 89%), the median WBC, hemoglobin and platelets were 3.1 × 109/L, 9.5 g/dL, and 65 × 109/L, respectively; pts were low, int-1, int-2, and high-risk MDS in 3%, 42%, 26%, 29%, respectively. The median TFS and OS were 31 (95% CI: 27– 37) and 34 (95% CI: 30 – 44) mos respectively. Assessing CA as time-dependent covariate, patients with CA had a worse TFS and OS, with a median TFS and OS of 16 and 18 mos compared to 56 and 60 mos, respectively in pts without CA. Based on the multivariable Cox model and after adjusting for effects of all other covariates, pts who had acquired CA had an increased risk of transformation (HR=1.46; p-value = 0.01) or death (HR=1.50; p-value = 0.01). By multivariate analysis, female pts with prior chemotherapy had an increased risk of developing CA (OR= 5.26; p-value <0.0001). 96 pts had history of previous malignancy treated with chemotherapy +/− radiation therapy. Of those, 34 (35%) patients acquired CA. Median time from previous chemotherapy to the acquisition of CA was 61 mos (range, 11 to 180). Pts previously treated who did not acquire CA had similar outcomes to those who had never been treated and did not develop CA, while those who did develop CA whether they were previously treated or not had worse TFS and OS. Conclusion: CA occurs at a rate of 29% of pts with lower risk MDS, more common among pts with previously treated malignancy, and has a significant impact on TFS and OS, possibly reflecting genomic instability in the natural history of MDS.

BackgroundFew studies specifically investigating elderly patients on peritoneal dialysis (PD) have been conducted and great uncertainty remains on the factors involved in the vital prognosis. The objective of this study was to describe our population of patients aged 75 years or older at the time PD was initiated and to study their survival in terms of the relevant nephro-geriatric criteria inventoried at the beginning of treatment.MethodsWe retrospectively analyzed the data of all the elderly patients that began first-line PD in our center between 1 January 1997 and 31 July 2006 ( n = 112).ResultsMean duration of survival on PD was 19.6 ± 13.9 months; by the end of the study 87 patients had died and 7 had been transferred to hemodialysis. The Cox model multivariate analysis of survival allowed us to select 5 independent predictive variables that had a considerable impact on survival: absence of nephrologic care before dialysis, associated comorbidities (Charlson Comorbidity Index), loss of physical and/or mental autonomy (AGGIR group), and polymedication. Above and beyond the weight of these clinical variables, institutionalization or, more generally, social isolation was a determining factor for the duration of survival in PD.ConclusionAny patient considered for peritoneal dialysis should be evaluated by a multidisciplinary team in collaboration with geriatric specialists for both the overall medical situation and the social and family environment.

Background Studies in hemodialysis patients suggest that hyponatremia is associated with increased mortality. However, results from peritoneal dialysis (PD) patients are discordant. We wished to establish whether there was an association between serum sodium and mortality risk in PD patients. Methods We analyzed 3,108 PD patients enrolled at day 90 of renal replacement therapy (RRT) into the UK Renal Registry (UKRR) data base with available serum sodium measurements (in 3 groups: ≤ 137, 138 - 140, ≥ 141 mmol/L) who were then followed up until death or the censoring date (31 December 2012). Analysis used Cox-regression with adjustment for age, sex, year of starting RRT, primary renal disease, serum albumin, smoking, and comorbidities. Results Unadjusted mortality rates were 118.6/1,000 person-years (py), 83.4/1,000 py, and 83.5/1,000 py for the lowest, middle, and highest serum sodium tertiles, respectively. After adjustment for covariates, patients in the lowest serum sodium group had almost 50% increased risk of dying compared with those with the highest serum sodium (hazard ratio [HR] 1.49, confidence interval [CI]:1.28 - 1.74), with a graded association between serum sodium and mortality. The association of serum sodium with mortality varied by age (p interaction < 0.001), and whilst this association attenuated after adjustment for confounding variables in the older age groups (55 - 64, and > 65 years), it remained in the younger age group of 18 - 54 years (HR 2.24 [1.36 – 3.70] in the lowest compared with the highest sodium tertile). Conclusions Lower serum sodium concentrations at the start of RRT in PD patients are associated with increased risk of mortality. Whilst this association may well be due to confounding in the older age groups, the persistent strong association between hyponatremia and mortality in the younger age group after adjustment for the available confounders suggests that prospective studies are required to assess whether active intervention to maintain serum sodium changes outcomes.

ObjectivesTo investigate the complications and survival of elderly patients with end-stage renal disease (ESRD) who received urgent-start peritoneal dialysis (USPD) or urgent-start haemodialysis (USHD), and to explore the value of peritoneal dialysis (PD) as the emergent dialysis method for elderly patients with ESRD.DesignRetrospective cohort study.SettingTwo tertiary care hospitals in Shanghai, China.ParticipantsChinese patients (n=542) >65 years of age with estimated glomerular filtration rate ≤15 mL/min/m2who received urgent-start dialysis between 1 January 2005 and 31 December 2015, and with at least 3 months of treatment. Patients who converted to other dialysis methods, regardless of the initial dialysis method, were excluded, as well as those with comorbidities that could significantly affect their dialysis outcomes.Primary and secondary outcome measuresDialysis-related complications and survival were compared. Patients were followed until death, stopped PD, transfer to other dialysis centres, loss to follow-up or 31 December 2016.ResultsThere were 309 patients in the USPD group and 233 in the USHD group. The rate of dialysis-related complications within 30 days after catheter implantation was significantly lower in the USPD group compared with the USHD group (4.5% vs 10.7%, p=0.031). The 6-month and 1, 2 and 3-year survival rates were 95.3%, 91.4%, 86.6% and 64.8% in the USPD group, and 92.2%, 85.7%, 70.2% and 57.8% in the USHD group, respectively (p=0.023). The multivariable Cox regression analysis showed that USHD (HR=2.220, 95% CI 1.298 to 3.790; p=0.004), age (HR=1.025, 95% CI 1.013 to 1.043, p<0.001) and hypokalaemia (HR=0.678, 95% CI 0.487 to 0.970; p=0.032) were independently associated with death.ConclusionsUSPD was associated with slightly better survival compared with USHD. USPD was associated with fewer complications and better survival than USHD in elderly patients with ESRD.
