Prolonged artificial liver support in a child with fulminant hepatic failure
1Division of intensive and Critical Care Medicine, Kumamoto University School of Medicine, Japan.
Insights
This study highlights a successful combined treatment using plasma exchange and continuous hemodiafiltration for a child with fulminant hepatic failure awaiting liver transplantation. This artificial liver support sustained the patient for 54 days, maintaining vital functions.
Area of Science:
- Hepatology and Transplant Surgery
- Critical Care Medicine
- Biomaterials Science
Background:
- Liver transplantation from brain-dead donors is not yet established in Japan.
- Fulminant hepatic failure (FHF) presents a critical challenge requiring urgent liver support.
- Existing artificial liver support systems have limitations in sustaining patients long-term.
Observation:
- A pediatric patient with FHF was managed with combined plasma exchange (PE) and continuous hemodiafiltration (CHDF).
- A high-performance polymethylmethacrylate (PMMA) membrane was utilized in the CHDF circuit.
- The combined therapy successfully sustained the patient for 54 days prior to living-donor liver transplantation.
Findings:
- The combined PE and CHDF treatment effectively maintained blood coagulation parameters.
- The therapy also appeared to preserve the patient's level of consciousness.
- This approach served as a crucial bridge to transplantation in a challenging clinical scenario.
Implications:
- The combined PE and CHDF technique shows promise as a life-sustaining measure for pediatric FHF patients awaiting liver transplantation.
- Further research is warranted to optimize artificial liver support systems for improved outcomes.
- This clinical experience provides valuable insights for managing critical liver failure in regions with limited organ donor options.
Abstract:
In Japan, liver transplantation from brain dead donors has not yet started. The authors present the first report of a clinical experience with a child with fulminant hepatic failure in whom the combined treatment of plasma exchange and continuous hemodiafiltration using a high-performance polymethylmethacrylate membrane was used successfully to sustain life for a period of as long as 54 days before liver transplantation from a living donor could be performed. The combination of plasma exchange and continuous hemodiafiltration appeared to maintain blood coagulation and level of consciousness effectively. Although the combined use of plasma exchange and continuous hemodiafiltration is still unsatisfactory as an artificial liver support, the authors suggest that this technique may be useful to support the life of a child who awaits liver transplantation.
