Insights
Continuous Renal Replacement Therapy (CRRT) effectively manages metabolic emergencies like hyperammonemia and high leucine levels in pediatric patients. This study highlights CRRT
Area of Science:
- Pediatric Critical Care Medicine
- Nephrology
- Metabolic Disorders
Background:
- Continuous Renal Replacement Therapy (CRRT) is established for acute kidney insufficiency (AKI).
- Emerging use of CRRT in managing acute metabolic disorders, including hyperammonemia and elevated leucine levels.
- Study focuses on CRRT application in a pediatric intensive care unit (PICU) setting.
Purpose of the Study:
- To describe the experience with CRRT in treating acute decompensation of pediatric patients with metabolic disorders.
- To evaluate the efficacy of CRRT in managing hyperammonemia and elevated leucine levels.
- To report on the application of CRRT in a PICU over a one-year period.
Main Methods:
- Retrospective evaluation of pediatric patients treated with CRRT for acute metabolic crisis.
- Analysis of 14 patients admitted to the PICU between November 2014 and December 2015.
- Inclusion of patients with hyperammonemia and elevated leucine levels due to various metabolic disorders.
Main Results:
- 14 pediatric patients received CRRT for metabolic disorders.
- 10 patients had hyperammonemia, and 4 had elevated leucine levels.
- CRRT modalities included continuous veno-venous hemodiafiltration (CVVHDF) and continuous veno-venous hemodialysis (CVVHD) with high throughput settings.
Conclusions:
- CRRT is an efficient treatment for metabolic emergencies such as hyperammonemia and elevated leucine levels.
- The study supports the use of CRRT in managing severe metabolic decompensation in pediatric patients.
- CRRT demonstrates effectiveness in addressing life-threatening metabolic crises.
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.
