Nutrition in critically ill children with acute kidney injury on continuous kidney replacement therapy: a 2023 executive summary. Nutrition 2024; 119:112272. [PMID: 38118382 DOI: 10.1016/j.nut.2023.112272] [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: 06/23/2023] [Revised: 10/04/2023] [Accepted: 10/21/2023] [Indexed: 12/22/2023]
Abstract
OBJECTIVES Nutrition plays a vital role in the outcome of critical illness in children, particularly those with acute kidney injury. Currently, there are no established guidelines for children with acute kidney injury treated with continuous kidney replacement therapy. Our objective was to create clinical practice points for nutritional assessment and management in critically ill children with acute kidney injury receiving continuous kidney replacement therapy. METHODS An electronic search using PubMed and an inclusive academic library search (including MEDLINE, Cochrane, and Embase databases) was conducted to find relevant English-language articles on nutrition therapy for children (<18 y of age) receiving continuous kidney replacement therapy. RESULTS The existing literature was reviewed by our work group, comprising pediatric nephrologists and experts in nutrition. The modified Delphi method was then used to develop a total of 45 clinical practice points. The best methods for nutritional assessment are discussed. Indirect calorimetry is the most reliable method of predicting resting energy expenditure in children on continuous kidney replacement therapy. Schofield equations can be used when indirect calorimetry is not available. The non-intentional calories contributed by continuous kidney replacement therapy should also be accounted for during caloric dosing. Protein supplementation should be increased to account for the proteins, peptides, and amino acids lost with continuous kidney replacement therapy. CONCLUSIONS Clinical practice points are provided on nutrition assessment, determining energy needs, and nutrient intake in children with acute kidney injury and on continuous kidney replacement therapy based on the existing literature and expert opinions of a multidisciplinary panel.

Abstract
BACKGROUND Nutrition plays a vital role in the outcome of critically ill children, particularly those with AKI. Currently, there are no established guidelines for children with AKI treated with continuous RRT (CRRT). A thorough understanding of the metabolic changes and nutritional challenges in AKI and CRRT is required. Our objective was to create clinical practice points for nutritional assessment and management in critically ill children with AKI receiving CRRT. METHODS PubMed, MEDLINE, Cochrane, and Embase databases were searched for articles related to the topic. Expertise of the authors and a consensus of the workgroup were additional sources of data in the article. Available articles on nutrition therapy in pediatric patients receiving CRRT through January 2023. RESULTS On the basis of the literature review, the current evidence base was examined by a panel of experts in pediatric nephrology and nutrition. The panel used the literature review as well as their expertise to formulate clinical practice points. The modified Delphi method was used to identify and refine clinical practice points. CONCLUSIONS Forty-four clinical practice points are provided on nutrition assessment, determining energy needs, and nutrient intake in children with AKI and on CRRT on the basis of the existing literature and expert opinions of a multidisciplinary panel.

Abstract
INTRODUCTION Herein, we aimed to discuss our experience in 16 newborn patients with Maple syrup urine disease (MSUD) who were treated with urgent renal replacement therapy (RRT). METHODS The patients underwent continuous veno-venous hemodiafiltration (CVVHDF) or peritoneal dialysis (PD) as renal replacement therapy. RESULTS Eleven (68.75%) patients underwent CVVHDF and five (31.25%) underwent peritoneal dialysis. The median leucine reduction rate per hour was 2.56%(1.75-7.6) in the CVVHDF group, 0.78%(0.54-1.83) in the PD group, and was significantly higher in the CVVHDF group (p = 0.001). Post-treatment plasma leucine levels were found to be 198 (20-721) μmol/L in the CVVHDF group and 600 (250-967) μmol/L in the PD group, and CVVHDF was found to be significantly lower (p = 0.08). Complications such as hypotension, electrolyte imbalance, and filter obstruction occurred in the CVVHDF group. CONCLUSION This study showed that CVVHDF is more effective than PD for rapidly eliminating elevated leucine levels caused by MSUD in the newborn and it is not associated with increased complication rates.

Abstract
OBJECTIVES Accurate management of metabolic decompensation in maple syrup urine disease (MSUD) has a crucial role, as acute attacks can cause neurological sequels and can be life threatening. Here, we aimed to evaluate effect of sodium phenylbutyrate (NaPBA) in acute management of MSUD attacks. METHODS Episodes with an initial plasma leucine (Leu) level above 750 µmoL/L and that require hospitalization due to clinical findings of Leu neurotoxicity and/or feeding difficulties were included to the study. Patients who had no molecular diagnosis and a regular follow-up were excluded. Clinical findings, laboratory results and therapy responses were reviewed, retrospectively. RESULTS Ten patients who experienced 19 distinct episodes of MSUD attacks were enrolled. Initial median Leu level was 901.67 (range 756-1989.11) and 33.9 µmoL/L (range 7.91-347.3 µmoL/L) at the end of therapy. None of our patients underwent extracorporeal toxin removal during the course of attack. In patients with serial plasma quantitative amino acid sampling, mean Leu reduction rate was calculated to be 529.68 ± 250.08 µmoL/L/day at the 24th h of treatment and 318.72 ± 191.52 µmoL/L/day at the 48th h of treatment. CONCLUSIONS This study is the first original study that investigates the effect of NaPBA in management of acute attacks of MSUD patients from Turkey. We suggest that NaPBA treatment in MSUD attacks can ameliorate clinical and biochemical findings. This therapeutic option should be considered especially in smaller centers without the toxin removal chance and for patients who were not appropriate for extracorporeal toxin removal like hemodynamic instability.

Eur J Pediatr 2019; 178:829-836. [PMID: 30895385 DOI: 10.1007/s00431-019-03361-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 02/23/2019] [Accepted: 03/04/2019] [Indexed: 12/31/2022]
Abstract
Several recent studies have reported that toxic metabolites accumulated in the body as a product of inborn errors of metabolism (IEM) are eliminated more rapidly with continuous venovenous hemodiafiltration (CVVHDF) than with peritoneal dialysis (PD). However, there is still uncertainty about the impacts of dialysis modalities on the short-term outcome. Here, it was aimed to investigate the effects of dialysis modalities on the short-term outcome. This retrospective study included 40 newborn infants who underwent PD (29 patients) or CVVHDF (11 patients) due to inborn errors of metabolism at a tertiary centre, between June 2013 and March 2018. The outcomes and the potential effects of the dialysis modality were evaluated. Of 40 patients, 21 were urea cycle defect, 14 were organic academia, and 5 were maple syrup urine disease. The median 50% reduction time of toxic metabolites were shorter in patients treated with CVVHDF (p < 0.05). Catheter blockage was the most common complication observed in PD group (24.1%), whereas in CVVHDF group hypotension and filter blockage were more common. There was no significant difference in mortality between dialysis groups (38% vs. 45.4%, p > 0.05). In patients with hyperammonaemia, duration of plasma ammonia > 200 μg/dL was the most important factor influencing mortality (OR 1.05, CI 1.01-1.09, p = 0.007).Conclusion: This study showed that CVVHDF is more efficient than PD to rapidly eliminate toxic metabolites caused by IEM in newborn infants, but not in improving survival. What is Known: •Toxic metabolites are eliminated more rapidly with CVVHDF than with PD. •Higher complication rates were reported with rigid peritoneal catheters in PD and catheter blockage in CVVHDF. What is New: •Prolonged duration of plasma ammonia levels above a safe limit (200 μg/dL) was associated with increased mortality. •Lower catheter-related complication rates may have been associated with the use of Tenckhoff catheters in PD and the use of right internal jugular vein in CVVHDF.

Continuous Renal Replacement Therapy with High Flow Rate Can Effectively, Safely, and Quickly Reduce Plasma Ammonia and Leucine Levels in Children. CHILDREN 2019; 6:children6040053. [PMID: 30987345 PMCID: PMC6518014 DOI: 10.3390/children6040053] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/12/2019] [Revised: 03/30/2019] [Accepted: 04/01/2019] [Indexed: 12/30/2022]
Abstract
Introduction: Peritoneal dialysis and continuous renal replacement therapy (CRRT) are the most frequently used treatment modalities for acute kidney injury. CRRT is currently being used for the treatment of several non-renal indications, such as congenital metabolic diseases. CRRT can efficiently remove toxic metabolites and reverse the neurological symptoms quickly. However, there is not enough data for CRRT in children with metabolic diseases. Therefore, we aimed a retrospective study to describe the use of CRRT in metabolic diseases and its associated efficacy, complications, and outcomes. Materials and Methods: We performed a retrospective analysis of the records of all patients admitted in the pediatric intensive care unit (PICU) for CRRT treatment. Results: Between December 2014 and November 2018, 97 patients were eligible for the present study. The age distribution was between 2 days and 17 years, with a mean of 3.77 ± 4.71 years. There were 13 (36.1%) newborn with metabolic diseases. The patients were divided into two groups: CRRT for metabolic diseases and others. There was a significant relationship between the groups, including age (p ≤ 0.001), weight (p = 0.028), blood flow rate (p ≤ 0.001); dialysate rate (p ≤ 0.001), and replacement rate (p ≤ 0.001). The leucine reduction rate was 3.88 ± 3.65 (% per hour). The ammonia reduction rate was 4.94 ± 5.05 in the urea cycle disorder group and 5.02 ± 4.54 in the organic acidemia group. The overall survival rate was 88.9% in metabolic diseases with CRRT. Conclusion: In particularly hemodynamically unstable patients, CRRT can effectively and quickly reduce plasma ammonia and leucine.

Abstract
BACKGROUND While Continuous Renal Replacement Therapy (CRRT) is a well established treatment modality for patients with acute kidney insufficiency (AKI), it is now also being used for the management of various illnesses such as acute metabolic disorders presenting with hyperammonemia and elevated leucine levels. Herein, we aimed to describe our experience with CRRT in treatment of acute decompensation of 14 patients with a diagnosis of metabolic disorder who has been admitted to our pediatric intensive care unit (PICU) in the last year. METHODS Patients who have had life threatening acute metabolic crisis due to various metabolic disorders and were treated with continuous renal replacement therapy (CRRT) were evaluated retrospectively. RESULTS Between November 2014 and December 2015, 14 patients were found to have received CRRT for various metabolic disorders in the PICU. Ten patients had hyperammonemia and four patients had elevated leucine levels. Nine patients were male and five were female. The age interval was between 2 days and 18 months, with a mean of 5.5 ± 7.4 months. The weight distribution was between 2.5 and 18 kg, with a mean of 7.3 ± 5.6 kg. Eleven patients received continuous veno-venous hemodiafiltration (CVVHDF), and 3 patients with MSUD received continuous veno-venous hemodialysis (CVVHD). All patients have received high throughput hemodialysis and hemofiltration. The dialyzate rate was set to be minimum 4042 ml/h/1.73 m2, and maximum 12,900 ml/h/1.73 m2. Hemofiltration was performed with a replacement rate of 40-76 ml/kg/h. The average CRRT duration was 16.6 ± 15.6 h. CONCLUSIONS We suggest that CRRT is an efficient method that can be used in hyperammonemia and elevated leucine levels which are metabolic emergencies.

Abstract
AIM Some inborn errors of metabolism induce metabolic encephalopathy through accumulation of neurotoxic metabolites. Rapid elimination of these metabolites by peritoneal or extracorporeal dialysis is crucial to prevent neuronal damage or death. In this retrospective study, we evaluated the outcomes of nine neonates with metabolic crisis treated with peritoneal dialysis. METHOD Six neonates with hyperammonemic coma (four with organic acidemias, two with urea cycle disorders) and three with leucine accumulation due to maple syrup urine disease (MSUD) were managed with peritoneal dialysis in conjunction with dietary and pharmacological therapy. RESULTS Three patients with organic acidemia survived. One of the patients was normal; others had moderate and severe neurological impairments. One neonate with organic acidemia and both neonates with urea cycle disorders died. Two of the three patients with MSUD survived without neurological impairment; the other had severe neurological damage and died at 9 months of age due to sepsis. CONCLUSION Theoretically, extracorporeal dialysis should be the first dialysis treatment of choice; however, this report demonstrates that peritoneal dialysis has a chance to prevent neurological damage in some patients. Therefore, in developing countries without extracorporeal dialysis opportunities, it can be still a life-saving procedure, if it is applied with skilled staff and standard procedures.

Abstract
BACKGROUND Infants with hyperammonemia can present with nonspecific findings so ordering an ammonia level requires a high index of suspicion. Renal replacement therapy (RRT) should be considered for ammonia concentrations of >400 μmol/L since medical therapy will not rapidly clear ammonia. However, the optimal RRT prescription for neonatal hyperammonemia remains unknown. Hemodialysis and continuous renal replacement therapy (CRRT) are both effective, with differing risks and benefits. CASE-DIAGNOSIS/TREATMENT We present the cases of two neonates with hyperammonemia who were later diagnosed with ornithine transcarbamylase deficiency and received high-dose CRRT. Using dialysis/replacement flow rates of 8,000 mL/h/1.73 m(2) (1,000 mL/h or fourfold higher than the typical rate used for acute kidney injury) the ammonia decreased to <400 μmol/L within 3 h of initiating CRRT and to <100 μmol/L within 10 h. CONCLUSIONS We propose a CRRT treatment algorithm to rapidly decrease the ammonia level using collaboration between the emergency department and departments of genetics, critical care, surgery/interventional radiology, and nephrology.
