[Severe liver cytolysis could be a marker of the severity of hemorrhagic dengue: report of two cases].

We report two cases of severe dengue fever in persons returned from stays in endemic areas during the summer outbreak of 2010. Both presented a hemorrhagic syndrome associated with primary hemostasis disorders, neutropenia, and severe hepatic cytolysis without any hepatocellular insufficiency. Three days after hospitalization, the first patient's AST and ALT levels rose to 80 and 12 times the upper reference values respectively, and the second patient's to 12 and 7 times those values.
