[PMID: 38504636 DOI: 10.1111/hdi.13147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 02/29/2024] [Accepted: 03/04/2024] [Indexed: 03/21/2024]
Abstract
BACKGROUND Dialysis disequilibrium syndrome (DDS) is a rare but significant concern in adult and pediatric patients undergoing dialysis initiation with advanced uremia or if done after an interval. It is imperative to gain insights into the epidemiological patterns, pathophysiological mechanisms, and preventive strategies aimed at averting the onset of this ailment. DESIGN Prospective observational quality improvement initiative cohort study. SETTING AND PARTICIPANTS A prospective single-center study involving 50 pediatric patients under 18 years recently diagnosed with chronic kidney disease stage V with blood urea ≥200 mg/dL, admitted to our tertiary care center for dialysis initiation from January 2017 to October 2023. QUALITY IMPROVEMENT PLAN A standardized protocol was developed and followed for hemodialysis in pediatric patients with advanced uremia. This protocol included measures such as lower urea reduction ratios (targeted at 20%-30%) with shorter dialysis sessions and linear dialysate sodium profiling. Prophylactic administration of mannitol and 25% dextrose was also done to prevent the incidence of dialysis disequilibrium syndrome. MEASURES Incidence of dialysis disequilibrium syndrome and severe dialysis disequilibrium syndrome, mortality, urea reduction ratios (URRs), neurological outcome at discharge, and development of complications such as infection and hypotension. Long-term outcomes were assessed at the 1-year follow-up including adherence to dialysis, renal transplantation, death, and loss to follow-up. RESULTS The median serum creatinine and urea levels at presentation were 7.93 and 224 mg/dL, respectively. A total of 20% of patients had neurological symptoms attributable to advanced uremia at the time of presentation. The incidence of dialysis disequilibrium syndrome was 4% (n = 2) with severe dialysis disequilibrium syndrome only 2% (n = 1). Overall mortality was 8% (n = 4) but none of the deaths were attributed to dialysis disequilibrium syndrome. The mean urea reduction ratios for the first, second, and third dialysis sessions were 23.45%, 34.56%, and 33.50%, respectively. The patients with dialysis disequilibrium syndrome were discharged with normal neurological status. Long-term outcomes showed 88% adherence to dialysis and 38% renal transplantation. LIMITATIONS This study is characterized by a single-center design, nonrandomized approach, and limited sample size. CONCLUSIONS Our structured protocol served as a framework for standardizing procedures contributing to low incidence rates of dialysis disequilibrium syndrome.

Dialysis disequilibrium syndrome (DDS) in pediatric patients on dialysis: systematic review and clinical practice recommendations. Pediatr Nephrol 2022; 37:263-274. [PMID: 34609583 DOI: 10.1007/s00467-021-05242-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 07/12/2021] [Accepted: 07/13/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND AND OBJECTIVES Dialysis disequilibrium syndrome (DDS) is a rare neurological complication, most commonly affecting patients undergoing new initiation of hemodialysis (HD), but can also be seen in patients receiving chronic dialysis who miss regular treatments, patients having acute kidney injury (AKI), and in those treated with continuous kidney replacement therapy (CKRT) or peritoneal dialysis (PD). Although the pathogenesis is not well understood, DDS is likely a result of multiple physiological abnormalities. In this systematic review, we provide a synopsis of the data available on DDS that allow for a clear picture of its pathogenesis, preventive measures, and focus on effective management strategies. METHODS We conducted a literature search on PubMed/Medline and Embase from January 1960 to January 2021. Studies were included if the patient developed DDS irrespective of age and gender. A summary table was used to summarize the data from individual studies and included study type, population group, age group, sample size, patient characteristics, blood and dialysate flow rate, and overall outcome. A descriptive analysis calculating the frequency of population size, symptoms, and various treatments was performed using R software version 3.1.0. RESULTS A total of 49 studies (321 samples) were identified and analyzed. Out of the included 49 studies, a total of 48 studies reported the presence of DSS among patients (1 study reported based on number of dialysis and therefore was not considered for analysis). Among these 48 studies, 74.3% (226/304) patients were reported to have DSS. The most common symptoms were nausea (25.2%), headache (24.8%), vomiting (23.9%), muscle cramps (18.1%), affected level of consciousness (8.8%), confusion (4.4%), and seizure (4.9%) among the 226 DDS patients. Furthermore, 12 studies decided to switch from HD to alternative dialysis modalities including continuous venovenous hemofiltration/hemodiafiltration (CVVH/CVVHDF) or PD which reported no DDS symptoms. CONCLUSION Early recognition and timely prevention are crucial for DDS patients. We have provided comprehensive clinical practice points for pediatric, adolescent, and young adult populations. However, it is essential to recognize that DDS was reported more frequently in the early dialysis era, as there was a lack of advanced dialysis technology and limited resources.

Abstract
In the last three decades, significant advances have been made in the care of children requiring renal replacement therapy (RRT). The move from the use of only hemodialysis and peritoneal dialysis to continuous venovenous hemofiltration with or without dialysis (continuous renal replacement therapy, CRRT) has become a mainstay in many intensive care units. The move to CRRT is the result of greater clinical experience as well as advances in equipment, solutions, vascular access, and anticoagulation. CRRT is the mainstay of dialysis in pediatric intensive care unit (PICU) for critically ill children who often have hemodynamic compromise. The advantages of this modality include the ability to promote both solute and fluid clearance in a slow continuous manner. Though data exist suggesting that approximately 25% of children in any PICU may have some degree of renal insufficiency, the true need for RRT is approximately 4% of PICU admissions. This article will review the history as well as the progress being made in the provision of this care in children.

Regional citrate anticoagulation for continuous renal replacement therapy in children. Pediatr Nephrol 2017; 32:703-711. [PMID: 27896442 DOI: 10.1007/s00467-016-3544-9] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2016] [Revised: 10/24/2016] [Accepted: 10/27/2016] [Indexed: 12/29/2022]
Abstract
BACKGROUND Anticoagulation of the continuous renal replacement therapy (CRRT) circuit is an important technical aspect of this medical procedure. Most studies evaluating the efficacy and safety of citrate use have been carried out in adults, and little evidence is available for the pediatric patient population. The aim of this study was to compare regional citrate anticoagulation versus systemic heparin anticoagulation in terms of the lifetime of hemofilters in a pediatric population receiving CRRT at a pediatric center in Bogota, Colombia. METHODS This was an analytical, observational, retrospective cohort study in which we assessed the survival of 150 hemofilters (citrate group 80 hemofilters, heparin group 70 hemofilters) used in a total of 3442 hours of CCRT (citrate group 2248 h, heparin group 1194 h). Hemofilter survival was estimated beginning at placement and continuing until filter replacement due to clotting or high trans-membrane pressures. RESULTS Hemofilter survival was higher in the citrate group than in the heparin group (72 vs. 18 h; p <0.0001). Bivariate analysis showed that the hemofilter coagulation risk was significantly increased when heparin was used, regardless of hemofilter size and pump flow (hazard ratio 3.70, standard error 0.82, 95% confidence interval 2.39-5.72; p <0.00001). CONCLUSIONS Regional citrate anticoagulation could be more effective than heparin systemic anticoagulation in terms of prolonging the hemofilter lifetime in patients with acute renal injury who require CRRT.

Abstract
OBJECTIVE To provide the pediatric intensivist an in-depth understanding of citrate as regional anticoagulant during continuous renal replacement therapy. DATA SOURCES AND DATA SELECTION We searched the PubMed.gov database using the initial key words: citrate anticoagulation [title] AND continuous; citrate [title] AND pediatric AND continuous; prospective pediatric renal replacement AND citrate; and regional citrate anticoagulation. Additional searchers were performed using EMBASE, CINAHL, and SCOPUS with similar keywords and limits. Further articles were gathered from bibliographic references of relevant studies and reviews. Only articles published in English were reviewed. DATA EXTRACTION AND DATA SYNTHESIS In the pediatric population, there are no prospective interventional or randomized studies comparing regional versus systemic anticoagulation. However, there are 11 (retrospective and prospective observational studies) in the pediatric population using citrate anticoagulation. These studies have shown that regional citrate anticoagulation in the pediatric population can be effective, provide equivalent circuit survival, and decrease bleeding compared with heparin anticoagulation. In the adult population, there are six prospective randomized controlled trials comparing the efficacy of regional citrate anticoagulation versus heparin. Two systematic reviews with meta-analysis of these six trials have been performed. The adult data on the use of regional citrate anticoagulation during continuous renal replacement therapy show a decreased risk of bleeding and at the least equivalent circuit survival as compared to heparin. Current pediatric and adult studies support regional citrate anticoagulation as an effective alternative to systemic heparin anticoagulation in most patient populations. CONCLUSIONS Continuous renal replacement therapy is the most common modality of renal replacement in the critical care setting. Regional anticoagulation is an ideal option in a critically ill child after recent surgery or with coagulopathy. Therefore, regional citrate anticoagulation in the pediatric critical care population requiring renal replacement therapy is commonly employed. Complications of citrate anticoagulation can be avoided with a greater understanding of the properties and clearance of citrate. Continued reporting of observational data and the development of prospective multicenter trials using citrate anticoagulation are needed to ensure safe and standardized care in the pediatric population.

Abstract
This article provides the bedside clinician an overview of the unique renal complications that are seen commonly in the pediatric intensive care unit. These sections are purposely succinct to give a quick guide to the clinician for the care of these children. We have identified four major areas that should result in discussion and cooperative care between intensive care physicians and nephrologists for the care of these children: (1) hypertension, (2) chronic kidney failure, (3) acute kidney injury, and (4) renal replacement therapy.
