[Fulminant course of falciparum malaria].

METHODS

A 57-year-old white man had been travelling in Kenya for vacation until 14 days before admission. Due to apprehension about side effects, the patient had refused any malaria prophylaxis. Ten days before admission he developed low grade temperatures and suffered from pain in the limbs, from nausea and vomiting. A new episode of tachyarrhythmia was diagnosed two days before admission and was treated by his general practitioner. Finally he was admitted to our hospital because of high temperatures, chills and progressive clinical deterioration. Autopsy revealed prominent congestion of liver, spleen and cerebral vessels as well as subdural and subarachnoidal hemorrhage.

METHODS

In both thin and thick peripheral blood smears Plasmodium parasites were demonstrated in approximately 30% of the eryhthrocytes and the diagnosis of Plasmodium falciparum was immediately confirmed by an immunological test.

METHODS

Due to the fulminant clinical and neurological deterioration with progressive hypoxaemia, the patient required ventilator therapy already one hour after admission. Therapy with chinine and doxycycline was initiated and exchange transfusion was considered. However, due to hyperkalaemia and cardiac arrest, the patient died 4 hours after admission due to parasitic hemolysis.

CONCLUSIONS

Severe Plasmodium falciparum infection in non-immunized patients is a medical emergency and requires immediate diagnosis and treatment. Malaria should always be considered in the differential diagnosis in persons who have travelled to endemic areas and presenting not only with temperatures, but also with non-specific clinical signs, like cardiac arrhythmias. Although never entirely effective, chemoprophylaxis is highly recommended.
