Pediatric Acute Liver Failure: Current Perspectives
Keywords:

It is well known that acute liver failure (ALF) in children is rare but potentially a
life-threatening disorder. Its true incidence in the pediatric population is undetermined but is
responsible for 10-15% of all pediatric liver transplantations.1
Unlike adults, a specific cause
of pediatric ALF is not identified in almost half of the cases,2
and the etiology is classified as
indeterminate in 18-47% of all patients.1
The etiology is important because the survival rate and
need for liver transplantation vary depending on the diagnosis. Spontaneous recovery is better
in children with toxic etiology and worst for those with indeterminate or other causes.1,2 There
is no specific treatment for most ALF cases, and the mainstay of medical care is to minimize
complications and to limit additional morbidity.3
ALF can be associated with rapidly progressive multiorgan failure and high mortality rates. One of the leading causes of death is cerebral
edema and intracranial hypertension (ICH), responsible for about 20-25% of all deaths.3
From
that perspective, it is desirable to develop new therapies/technologies for diagnostic investigation and interventions.
