Abstract

Dengue has emerged as an important arboviral disease with significant impact on the disease burden in population residing in tropical countries. Dengue is spread by the bite of Aedes mosquito. The virus seems to have some hepatotoxic effects. Affliction of liver in form of derangements in the liver function tests is common and may include mild elevations in serum bilirubin, elevated transaminases and derangements in serum albumin. Although asymptomatic in most cases, clinical manifestations like jaundice, and acute liver failure (ALF) may occasionally complicate the clinical picture. Indeed, dengue has been implicated as an important cause of ALF in endemic countries. The present review focuses on the hepatic manifestations and the pathogenesis of the liver injury in dengue.

Keywords: Dengue, Liver, Viral hepatitis, Acute liver failure, Transaminases, Bilirubin

Core tip: Dengue is an important cause of febrile illness in the tropical countries. It may affect the liver but the hepatic involvement is usually asymptomatic. However it is recognized as an important cause of acute hepatic failure in endemic counties. Dengue must be considered as a differential in the evaluation of acute hepatic failure and as an acute precipitant in patients presenting with acute on chronic liver failure.
