History

The classic signs of Donath-Landsteiner hemolytic anemia (DLHA) include a sudden onset of hemoglobinuria accompanied by pallor and mild jaundice. [8] Hemoglobinuria may be absent if the autoantibody level is not high enough to cause intravascular hemolysis. Patients and their caretakers may report dark, brown, black, or otherwise abnormally colored urine.

A preceding history of upper respiratory tract infection or other viral infection is common, particularly in the younger age group. Preceding exposure to cold may be elicited on the patient history. [10] It is not consistently reported, however. In fact, only 1 in 52 cases of DLHA reported by Sokol et al occurred after documented exposure to cold. [16]

Anemia may be mild, moderate, or severe.

High fevers, chills, back or leg pain, and abdominal cramping may also be reported, along with headache, nausea, vomiting, or diarrhea. These signs and symptoms typically resolve early in the clinical course. Some may be secondary to the causative viral infection.
