Abstract
Abstract: Pediatric acute liver failure (pALF) poses a formidable clinical challenge characterized by rapid hepatocyte necrosis and pro-inflammatory events. The urgency of pALF necessitates advanced therapeutic modalities, prompting the exploration of high-volume plasma exchange (HVPE) as a sophisticated intervention. This case report delves into the intricate management of a 16-year-old female with hyperacute liver failure secondary to hepatitis A, highlighting the critical need for nuanced and multidisciplinary approaches. The case unfolds through a detailed description of symptoms, clinical decision-making, and the therapeutic journey. The management includes a calculated deferral of liver transplantation in favor of HVPE, with a focus on the rationale for choosing HVPE over continuous renal replacement therapy. Technical aspects of the procedure, such as blood volume calculations and procedural details, are meticulously outlined. Laboratory investigations track the patient’s progress, showcasing the profound impact of HVPE on clinical and laboratory recovery. The patient’s response to HVPE is evident in the comprehensive clinical and laboratory recovery observed after the intervention. The resolution of encephalopathy, successful extubation, and eventual discharge highlight the positive outcomes achieved through the judicious application of HVPE. However, the procedure is not without challenges, as the emergence of hypertension during the second and third cycles and a lone episode of seizure require swift and careful management. The management of pALF demands a sophisticated and multidimensional approach, especially when liver transplantation is not immediately feasible. This case report underscores the nuanced decision-making involved in selecting extracorporeal therapies, with a focus on the successful application of HVPE. HVPE, as recommended by the American Society for Apheresis, emerges as a promising intervention in the context of pALF, offering a viable option when liver transplantation is deferred due to advanced encephalopathy. The favorable outcomes and considerations of cost-effectiveness and procedural simplicity further accentuate the potential of HVPE as a cornerstone in the critical care of pediatric patients with acute liver failure.
