Autoimmune Hemolysis Anemia After Dihydroartemisinin and Piperaquine for Uncomplicated Plasmodium Falciparum Malaria
Abstract BackgroundMalaria is still an endemic disease in Africa with many imported cases in Europe. The standard treatment is intravenous artesunate for severe malaria and oral artemisinin-based combination therapy (ACT) for uncomplicated malaria. Delayed hemolytic anemia (DHA) after intravenous artesunate has been extensively described and guidelines recommend a biological monitoring until one month after the end of the treatment. The link with an autoimmune process is unsure. Nevertheless, cases with positive direct antiglobulin test (DAT) have been reported. Conversely, DHA is not recognized as an adverse effect of oral ACT. Previously, only two cases of DHA occurring after oral ACT without intravenous artesunate administration have been reported. Case presentationWe report the case of a 42 year old man returning from Togo. He was treated with dihydroartemisinin / piperaquine combination for an uncomplicated Plasmodium falciparum malaria. Nine days after the end of the treatment he developed hemolytic anemia with positive DAT. Eventually, the patient recovered after corticotherapy. ConclusionThis is the first case report of autoimmune hemolytic anemia after treatment with dihydroartemisinin and piperaquine..
