Haemophagocytic Syndrome in a 19-Year-Old Male with Plasmodium falciparum Malaria

Objectives: Infectious agents triggering haemophagocytic lymphohistiocytosis (HLH) primarily involve the herpes virus group. We report a case of HLH precipitated by Plasmodium falciparum. Materials and methods: Clinical and laboratory findings in a patient presenting with fever were collected. After confirmation of acute malaria, anti-malarial treatment was administered. Results: Despite initial favourable evolution, the patient developed fever again together with a worsening of the haematological parameters and increased ferritin levels. A bone marrow biopsy confirmed the diagnosis of HLH. Conclusion: This case illustrates that HLH should be considered in the differential diagnosis of acute malaria in patients with persisting fever and pancytopenia.
