-Cerebral malaria is commonly the severe form of malaria -However, other acute complications may occur
Our case illustrates an unusual severe presentation of malaria
A 43 years old Lebanese nun was admitted to the hospital for fever appearing one week later after her returning from Africa where she stayed 5 weeks in Gana.
The diagnosis of malaria due to Plasmodium falciparum was done based on blood films.
She was treated by Mefloquine(Lariam⁰) one dose 750mg PO then 500 mg 6 hours later and 250 mg 12 hours later.
After the end of the treatment and 2 days fever free, the patient had more again a high fever (40- 41⁰C), without any neurological symptoms or signs.
Parasitemia (of Plasmodium) searched on thick and thin blood film was absent.
An extended work-up for tropical and other ID was done . All was negative(TB,Brucella, Salmonella,HIV, HBV,BC,…). TEE and high speed 64 multibarett CT-Scan of the chest, abdomen and pelvis were normal(apart an hepatosplenomegaly).
During this period, the nun developed a pancytopenia , high ferritinemia(>2000 ng/ml), hypertriglyceridemia and high LDH.
A severe dyspnea due to ARDS (Acute Respiratory Distress Syndrome) has leaded us to use the mechanical ventilation.

After 3 days of ventilation and iv methylprednisolone (500 mg bolus over 3 days), the patient status recovered successfully.
ETIOLOGIES OF HEMOPHAGOCYTIC SYNDROME • Infections: • Virus: Herpes group • Bacteria: Mycobacteria • Parasites: Leishmania, Plasmodium • Cancer:non- Hodgkin lymphoma • Auto- immune disease: SLE, Still Disease, Juvenile arthritis • Drugs:anti- seizures, minocycline, glucopeptide, cotrimoxazole, … • Unkown • Larroche C and Mouthon L, Autoimmun Rev , 2004, 3: 69- 75
