Pediatric liver transplantation for acute liver failure

Area of Science:

• Hepatology
• Transplant Surgery
• Pediatric Gastroenterology

Background:

• Acute liver failure (ALF) necessitates liver transplantation (LT) for survival in non-recovering patients.
• Timely diagnosis and referral to transplant centers are critical for successful ALF management.
• Low organ donation rates pose challenges for timely LT in some regions.

Purpose of the Study:

• To evaluate the outcomes of pediatric patients undergoing liver transplantation for acute liver failure.
• To assess the feasibility of rapid donor preparation in a low organ donation setting.

Main Methods:

• Retrospective review of 12 pediatric ALF patients who underwent LT over a 3-year period.
• Analysis of transplant indications, graft types, patient demographics, and post-transplant outcomes.
• Evaluation of donor preparation time, including liver tissue biopsy.

Main Results:

• Common indications included hepatitis A, non-A, non-E hepatitis, autoimmune hepatitis, Wilson's disease, mushroom poisoning, and toxic hepatitis.
• All patients initially recovered from hepatic coma post-transplant.
• Survival rates were high, with 9 of 12 patients healthy at follow-up (2-46 months).
• Two early deaths occurred due to ARDS and sepsis; one patient died after retransplantation for chronic rejection.
• Donor preparation time was reduced to approximately 4 hours.

Conclusions:

• Liver transplantation is a life-saving intervention for pediatric acute liver failure.
• Efficient donor preparation protocols can facilitate timely LT, even in resource-limited settings.
• Despite challenges, successful outcomes are achievable with prompt surgical intervention.
