Abstract
BACKGROUND

Malaria-associated secondary hemophagocytic lymphohistiocytosis (HLH) is rare. Moreover, the literature on malaria-associated HLH is sparse, and there are no similar cases reported in China.

CASE SUMMARY

We report the case of a 29-year-old woman with unexplained intermittent fever who was admitted to our hospital due to an unclear diagnosis. The patient concealed her history of travel to Nigeria before onset. We made a diagnosis of malaria-associated secondary HLH. The treatment strategy for this patient included treatment of the inciting factor (artemether for 9 d followed by artemisinin for 5 d), the use of immunosuppressants (steroids, intravenous immunoglobulin) and supportive care. The patient was discharged in normal physical condition after 25 d of intensive care. No relapses were documented on follow-up at six months and 1 year.

CONCLUSION

Early diagnosis of the primary disease along with timely intervention and a multidisciplinary approach can help patients achieve a satisfactory outcome.

Core Tip: We found an unexpected association between malaria and hemophagocytic lymphohistiocytosis (HLH) in this case. Literature on malaria-associated HLH is sparse. There are no similar cases reported in China. In this case, we made the diagnosis based on HLH-2004 criteria and adopted new biomarkers to make the diagnosis of HLH. Through multidisciplinary treatment, the patient was discharged in normal physical condition. This case highlights the importance of early diagnosis and timely therapy of the primary disease to secondary HLH.
