Abstract
Acute liver failure in children. Experience of a liver transplant center Background: Acute liver failure (ALF) in childhood is defined as biochemical evidence of liver injury, absence of known chronic liver disease and coagulopathy not corrected by vitamin K administration, with INR greater than 1.5 if the patient has encephalopathy or greater than 2.0 if the patient does not have encephalopathy. Objective: Report the experience of a single liver transplant center (LT) in the treatment of 8 children with ALF and review the literature. Method: Retrospective review of clinical charts of patients with ALF. Results: The median age was 8 years-old (range 0-11), three females. Five patients underwent LT. Two patients died, one of them LT. The etiologies were 4 undetermined, 1 autoimmune, 1 Wilson Disease, 1 Parvovirus and 1 chronic graft rejection. All grafts were from cadaver donor, 3 of them reduced. Two out of five patients with encephalopathy grade III-IV died. The one year survival rate was 75%. Conclusions: Children with ALF should be treated in experienced centers with facilities for liver transplant. Transplantation should be offered only if the underlying disease is treatable by liver replacement and if transplant prognosis is better than that of the underlying disease.
