The Efficacy and Outcomes of Renal Replacement Therapy in Pediatric Metabolic Disorders

OpenAlex English

Background/Objectives: This study aims to evaluate the efficacy and outcomes of renal replacement therapy (RRT) in pediatric patients with metabolic diseases, specifically focusing on the impact of hemodialysis (HD) and peritoneal dialysis (PD) on clinical parameters, toxin reduction, and long-term survival. Methods: This retrospective study included 10 pediatric patients (eight females and two males) treated at a pediatric nephrology department between 2020 and 2023. Patients diagnosed with metabolic disorders, including maple syrup urine disease (MSUD), methylmalonic acidemia (MMA), and glycogen storage disease (GSD), underwent RRT. Clinical data, demographic information, and biochemical parameters were collected and analyzed. Results: Among the patients, 50% were diagnosed with MSUD, 30% with MMA, and 20% with GSD. RRT, including HD and PD, was administered to manage acute metabolic crises. HD was particularly effective in rapidly reducing toxic metabolite levels. Patients treated with HD showed significant reductions in leucine and ammonium levels, with median reductions of 94.5% and 86%, respectively. Overall, 60% of the patients demonstrated long-term survival, highlighting the critical role of RRT in managing metabolic crises. In conclusion, RRT, including HD and PD, is crucial in managing pediatric metabolic disorders by effectively reducing toxic metabolite levels and improving clinical outcomes. Conclusions: The results of this study are consistent with previous research, highlighting the critical role of RRT in the acute management of metabolic crises and supporting its adoption as a standard treatment method.
