摘要
Acute liver failure(ALF)is a rare cause of liver-related mortality worldwide,with an estimated annual global incidence of more than one million cases.While drug-induced liver injury,including acetaminophen toxicity,is the leading cause of ALF in the Western world,viral infections remain a significant cause of ALF and the most common cause in many developing nations.Given the high mortality rates associated with ALF,healthcare providers should be aware of the broad range of viral infections that have been implicated to enable early diagnosis,rapid treatment initiation when possible,and optimal management,which may include liver transplantation.This review aims to provide a summary of viral causes of ALF,diagnostic approaches,treatment options,and expected outcomes.
