Abstract
Black water fever, also called malarial haemoglobinuria occurs exclusively with Plasmodium falciparum infection and is characterized by intravascular haemolysis with severe anaemia and intermittent passage of black coloured urine. It frequently leads to acute kidney injury (AKI) with increased morbidity and mortality. Although Sri Lanka has achieved remarkable success in eliminating malaria since 2016, still Sri Lanka gets malarial cases via overseas visitors from African countries and India. Here we report a case of black water fever complicated by AKI with a brief account of its pathophysiology.
