Blackwater fever

Blackwater fever is a complication of malaria infection in which red blood cells burst in the bloodstream (hemolysis), releasing hemoglobin directly into the blood vessels and into the urine, frequently leading to kidney failure. The disease was first linked to malaria by the Sierra Leone Creole physician John Farrell Easmon in his 1884 pamphlet entitled The Nature and Treatment of Blackwater Fever. Easmon coined the name "blackwater fever" and was the first to successfully treat such cases following the publication of his pamphlet.

Signs and symptoms

Within a few days of onset there are chills, with rigor, high fever, jaundice, vomiting, rapidly progressive anemia, and dark red or black urine.

Causes

The cause of hemolytic crises in this disease is unknown (mainly due to intravascular haemolysis). There is rapid and massive destruction of red blood cells resulting in hemoglobinemia (hemoglobin in the blood, but outside the red blood cells), hemoglobinuria (hemoglobin in urine), intense jaundice, anuria (passing less than 50 milliliters of urine in a day), and finally death in the majority of cases.Template:Citation needed

The most probable explanation for blackwater fever is an autoimmune reaction apparently caused by the interaction of the malaria parasite and the use of quinine. Blackwater fever is caused by heavy parasitization of red blood cells with Plasmodium falciparum. However, there have been other cases attributed to Plasmodium vivax,<ref>Template:Cite journal</ref> Plasmodium malariae,<ref>Template:Cite journal</ref> Plasmodium knowlesi.<ref>Template:Cite journal</ref>

Blackwater fever is a serious complication of malaria, but cerebral malaria has a higher mortality rate. Blackwater fever is much less common today than it was before 1950.<ref name=pmid12355996>Template:Cite journal</ref> It may be that quinine plays a role in triggering the condition,<ref>Template:Cite journal</ref> and this drug is no longer commonly used for malaria prophylaxis. Quinine remains important for treatment of malaria.<ref name="WHO22nd">Template:Cite book</ref>

Diagnosis

Blackwater fever should be suspected in a malaria patient who is intermittently passing dark-red to black urine, and is diagnosed using a urine dipstick test, which will be positive for hemoglobin. Microscopy of urine will be negative for erythrocytes.<ref>Template:Cite journal</ref>

Treatment

The treatment is antimalarial chemotherapy, intravenous fluid and sometimes supportive care such as intensive care and dialysis.Template:Cn

Society and culture

Prominent victims

• Brigadier General Charles Young first contracted malignant malaria, also known as blackwater fever, in 1913 during a military expedition in Liberia. Given his vulnerability to the disease, he and his family understood that military orders dispatching him back to Liberia in 1921 were akin to suicide, but he refused to retire from the U.S. Army or try to alter his military orders. He contracted the disease again during a visit to Nigeria and died in 1922. The U.S. Army posthumously promoted Young to Brigadier General in 2021.<ref>Template:Cite web</ref><ref>Template:Cite web</ref><ref>Template:Cite web</ref>
• Prior to his photography career, Henri Cartier-Bresson<ref>Template:Cite web</ref> contracted blackwater fever while hunting in Western Africa. Expecting to die, he sent instructions to his family on his wishes for a funeral. He made a full recovery.
• British mariner and naval officer Charles Lightoller contracted malaria c. 1897 during his tenure in Elder Dempster Lines. In his autobiography, he describes suffering from severe complications, including blackwater fever and a temperature of 106°F. He was treated by his shipmates and made a full recovery.Template:Citation needed

• Humanitarian and MMA fighter Justin Wren contracted malaria, which devolved into blackwater fever, while drilling water-wells for Congo Pygmies in 2013. The affliction nearly claimed Wren's life. He was misdiagnosed four times and required airlift to Uganda, where he narrowly recovered from severe symptoms.<ref>Template:Cite web</ref>
