Recrudescence of Plasmodium falciparum malaria 5 years after treatment in an HIV migrant: a case report with a peculiar presentation

Abstract

In the last two decades, several cases of delayed-onset malaria in migrants from endemic areas were reported. The decrease of acquired immunity over time, often enhanced by immune suppression, represents a possible underlying mechanism for recrudescence. Here we describe a case of Plasmodium falciparum malaria occurring five years after exposure in a patient infected with human immunodeficiency virus, originating from Ivory Coast. Peculiarly, bilateral subsegmental pulmonary SUMMARY embolism in the absence of deep venous thrombosis was also detected, requiring anticoagulant therapy. Treatment with dihydroartemisinin/piperaquine was followed by clearance of trophozoites and the patient was discharged home.
