Abstract
Refractory congestive heart failure (RCHF) is a common complication in the natural history of advanced heart failure. Peritoneal dialysis (PD) is a possible alternative in those patients, but studies are scarce, and mostly with small samples. We conducted this meta-analysis to evaluate the effects of PD in patients with RCHF. Articles published before July 2020 in the following databases: PubMed, Web of Science, and CENTRAL. Mean differences (MD) and 95% confidence intervals (CIs) were computed to generate a pooled effect size with a random effects model. We also assessed heterogeneity, risk of bias, publication bias, and quality of evidence. Twenty observational studies (n = 769) were included, with a "before and after intervention" design. PD was associated with a significant reduction in NYHA functional class (MD -1.37, 95% CI -0.78 to -1.96) and length of hospitalisation (MD -34.8, 95% CI -20.6 to -48.9 days/patient/year), a small but significant increase in left ventricular ejection fraction (MD 4.3, 95%CI 1.9 to 6.8%) and a non-significant change in glomerular filtration rate (MD -3.0, 95% CI -6.0 to 0 mL/min/1.73m2). Heterogeneity among studies was significant and overall risk of bias was rated from moderate to critical. No significant publication bias was found, and the overall quality of evidence was very low for all outcomes. PD in patients with RCHF improved functional class, length of hospitalisation, and ventricular functional, and had no impact in renal function. Further randomised clinical trials are warranted to confirm our results that showed some limitations.

A Single-Center Retrospective Study on the Initiation of Peritoneal Dialysis in Patients With Cardiorenal Syndrome and Subsequent Hospitalizations. Can J Kidney Health Dis 2020; 7:2054358120979239. [PMID: 33343912 PMCID: PMC7731593 DOI: 10.1177/2054358120979239] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Accepted: 10/29/2020] [Indexed: 11/17/2022] Open
Abstract
Background: Inotropic dependence and diuretic resistance in patients with cardiorenal syndrome (CRS) lead to frequent hospitalizations and are associated with high mortality. Starting peritoneal dialysis (PD) acutely (within 2 weeks of a heart failure hospitalization) offers effective volume removal without hemodynamic compromise in this population. There is little data on this approach in the North American literature. Objective: To determine whether volume-overloaded patients with CRS on maximal doses of diuretic therapy had reduced hospitalization for heart failure following PD initiation. Design: Retrospective cohort study. Setting: Academic hospital network (University Health Network, Toronto, Ontario). Patients: Patients with CRS receiving a bedside catheter and starting PD within 2 weeks of insertion at the University Health Network from January 1, 2013, to December 31, 2018. Methods and measurements: Data for heart failure–related hospitalizations and length of stay 6 months before and after PD initiation were collected. Patients who died, switched to hemodialysis, or were transferred to another facility within 6 months of starting PD were excluded from the analysis. Results: We identified 31 patients with CRS who had a bedside PD catheter inserted. The average age of patients was 66.0 ± 13.0 years. There were 7 (22.6%) deaths and 4 (12.9%) transfers to other programs or hemodialysis within 6 months of catheter insertion. After exclusion, we analyzed hospitalization and length of stay data for 20 patients. The hospitalization rate 6 months before PD initiation was 6.9 admissions per 1000 patient-days. This decreased to 2.5 admissions per 1000 patient-days after PD initiation. In addition, there was also a significant reduction in the average length of stay per hospitalization (24.1-3.9 days; P = .001). Limitations: Our study did not assess the severity of heart failure symptoms using a standardized functional classification system. We did not assess quality of life and illness intrusiveness scores before and after starting dialysis, nor did we capture non–heart-failure-related hospitalizations or external admissions at other hospital sites. We limited eligibility to clinically stable patients with no prior major abdominal surgical history in a single Canadian PD program using bedside ultrasound approach for catheter insertions by experienced nephrologists and included a small number of patients. Conclusions: Volume-overloaded patients with CRS receiving maximal diuretic therapy have lower hospitalization rates and shorter stays after initiation of PD. The development of a bedside PD catheter insertion program and close collaboration between nephrology and cardiology services may facilitate acute start dialysis in this population.

Abstract
Despite many medical and socioeconomic advantages, peritoneal dialysis (PD) is an underutilized dialysis modality that in most countries is used by only 5%-20% of dialysis patients, while the vast majority are treated with in-center hemodialysis. Several factors may explain this paradox, such as lack of experience and infrastructure for training and monitoring of PD patients, organizational issues, overcapacity of hemodialysis facilities, and lack of economic incentives for dialysis centers to use PD instead of HD. In addition, medical conditions that are perceived (rightly or wrongly) as contraindications to PD represent barriers for the use of PD because of their purported potential negative impact on clinical outcomes in patients starting PD. While there are few absolute contraindications to PD, high age, comorbidities such as diabetes mellitus, obesity, polycystic kidney disease, heart failure, and previous history of abdominal surgery and renal allograft failure, may be seen (rightly or wrongly) as relative contraindications and thus barriers to initiation of PD. In this brief review, we discuss how the presence of these conditions may influence the strategy of selecting patients for PD, focusing on measures that can be taken to overcome potential problems.

Usefulness of Peritoneal Ultrafiltration in Patients with Diuretic Resistant Heart Failure without End-Stage Renal Disease. Cardiorenal Med 2020; 10:429-439. [PMID: 33022682 DOI: 10.1159/000510249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Accepted: 05/11/2020] [Indexed: 11/19/2022] Open
Abstract
AIM This study aimed to explore the role of peritoneal ultrafiltration (UF) in cardiorenal syndrome (CRS) patients for fluid and metabolic control. BACKGROUND Peritoneal UF is safely and efficiently used for the management of CRS. It has been shown to provide efficient UF in hypervolemic patients. METHODS Thirty (20 males and 10 females) CRS patients were treated by peritoneal dialysis (PD) and UF. The baseline data of the patients (demographics, causes of heart failure, the presence of pacemaker or implantable cardioverter-defibrillator, the need for extracorporeal UF or paracentesis or thoracentesis, comorbidity, drugs, left ventricular ejection fraction [LVEF] and pulmonary artery systolic pressure [PAPs], pericardial effusion, physical examination, body weight, NYHA class, dialysis regime, urine output, N-terminal pro-B-type natriuretic peptide [NT-proBNP] level, hemoglobin, estimated glomerular filtration rate [eGFR], and other routine biochemical determinations) were recorded at the onset, every 6 months, and then annually. Echocardiograms were performed at baseline and after 6 and 12 months. The time points of complications associated with PD, the need for hemodialysis, the day of death, and causes of death were documented. RESULTS Mean age was 69 ± 8 years (range 49-84 years). The average PD duration was 18.25 ± 14.87 months. According to the CKD-EPI, initial mean GFR was 34.34 ± 11.9 mL/min/1.73 m2 (range 16.57-59.0), and this increased to 45.48 ± 26.04, 45.10 ± 28.58, and 41.10 ± 25.68 mL/min/1.73 m2 in the third, sixth, and twelfth months, respectively. There was a significant increase in the first 3 months and a significant decrease between the third and twelfth months (respectively, p = 0.018 and p = 0.043). There was no difference in eGFR levels between baseline and the end of the first year (p = 0.217). In the first 3 months, there was a significant decline in urea levels to 79.38 ± 36.65 from 109.92 ± 42.44 mg/dL and this was maintained until the end of the first year of PD therapy (after 3 months, p = 0.002; after 1 year, p = 0.024). However, there was no significant change in creatinine levels within the first year (p = 0.312). There was a significant increase in hemoglobin level up to the end of the first year of PD (after 3 months, p = 0.000; after 12 months, p = 0.013). There was a marked decrease in NT-proBNP levels in the first 6 months (p = 0.011). Functional capacity (according to NYHA classification) improved in all patients by the third month of PD treatment (p < 0.001). This early improvement was maintained in many patients during the following 12 months (p < 0.001). There was a marked decrease in NT-proBNP levels in the first 6 months (p = 0.011). At the end of the first year, there was an approximate 15% reduction in NT-proBNP levels (p = 0.647). Hospitalizations decreased to 6 ± 15 days/patient-year (range 18-122 days) from 62 ± 24 days/patient-year (p = 0.000). CONCLUSION Peritoneal UF is a treatment method that maintains renal function and electrolyte balance, improves cardiac function, and reduces hospitalizations in CRS patients. We observed that this treatment significantly increased functional capacity and quality of life and significantly reduced hospital admissions.

Abstract
Cardiorenal syndrome (CRS) is a multi-organ disease, encompassing heart, kidney and vascular system dysfunction. CRS is a worldwide problem, with high morbidity, mortality, and inflicts a significant burden on the health care system. The pathophysiology is complex, involving interactions between neurohormones, inflammatory processes, oxidative stress and metabolic derangements. Therapies remain inadequate, mainly comprising symptomatic care with minimal prospect of full recovery. Challenges include limiting the contradictory effects of multi-organ targeted drug prescriptions and continuous monitoring of volume overload. Novel strategies such as multi-organ transplantation and innovative dialysis modalities have been considered but lack evidence in the CRS context. The adjunct use of pharmaceuticals targeting alternative pathways showing positive results in preclinical models also warrants further validation in the clinic. In recent years, studies have identified the involvement of gut dysbiosis, uraemic toxin accumulation, sphingolipid imbalance and other unconventional contributors, which has encouraged a shift in the paradigm of CRS therapy.
