Hemoglobinuric bilious fever as a presentation of severe acute Plasmodium falciparum malaria

Abstract

Introduction: Hemoglobinuric bilious fever is one of the complications of severe malaria, infrequently notified, characterized by an acute intravascular hemolysis, massive in occasions, that leads to homoglobinuria and, finally to an acute renal lesion.

Objective: To describe a case of hemoglobinuric bilious fever as clinical presentation of severe acute malaria.

Clinical case: Male patient from a malaria-endemic area with a history of recurrent events of malaria, who, on the third day after receiving antimalarial chemoprophylaxis with mefloquine, presented with malaise, marked asthenia, fatigue, nausea, vomiting, diffuse abdominal pain, and scanty and dark urine emission, described by the patient as “Coca-Cola” like. Hemoglobinuric bilious fever was diagnosed as clinical presentation of severe acute malaria of low parasitemia, confirmed by malaria-positive quick diagnostic test and thick film, and massive homoglobinuria on urine dipstick test.

Conclusions: This case represents an uncommon presentation of the disease, which is not usually suspected. This paper alerts physicians working in malaria-endemic areas to be attentive. This dread complication could be the clinical presentation of severe malaria, especially in patients chronically exposed to Plasmodium falciparum infection, who present with massive acute hemolytic reaction in the absence of high parasitemia when quinine or mefloquine is administered as preventive or curative treatment against malaria.
