Rare case of self-limiting haemolysis associated with Dengue fever in a Sri Lankan female – case report

Abstract

A 61-year old female with dengue haemorrhagic fever developed anaemia and rising transaminase levels on the 6th day of illness. She was found to have haemolysis with a negative direct antiglobulin test (DAT), and no red cell fragmentation. She recovered with supportive care. Haemolysis with associated Haemolytic uraemic syndrome (HUS), Disseminated intravascular coagulation (DIC) and cold Auto-immune haemolytic anaemia (AIHA) is reported previously; DAT negative haemolytic anaemia associated with dengue fever has not. This case suggests a need for further studies on other immune mechanisms that can lead to haemolysis with dengue fever.
