Refractory pancytopenia and megaloblastic anemia due to falciparum malaria.J Trop Pediatr. 2011 Aug; 57(4):283-5.JT
Anemia is a common complication in malarial infection. Direct destruction and ineffective erythropoesis does not adequately explain the cause of anemia in malaria. We present a case with refractory megaloblastic anemia with asymptomatic falciparum malaria. We hypothesize that promoter variants in the inducible nitric oxide synthase gene might be the cause of severe refractory megaloblastic anemia and pancytopenia in our patient. Malaria should always be kept in mind as a cause of anemia especially in endemic areas even if the child is asymptomatic or there is no demonstrable parasite on routine smear examination.
