Mixed autoimmune hemolytic anemia in a 2-year-old girl

Abstract

Immune hemolytic anemia is diagnosed when it exhibits the clinical symptoms and laboratory findings of hemolytic anemia, such as pallor, jaundice, anemia, high indirect bilirubin, increased reticulocyte count, and a positive direct antiglobulin test. Depending on the type of antigenic stimulation, this condition can be divided into three distinct subtypes: (1) autoimmune hemolytic anemia (AIHA), (2) alloimmune hemolysis, and (3) drug-induced hemolysis. In addition, the thermal amplitude of autoantibodies is used to categorize AIHA as either a warm (most common), cold, or mixed (rare) subtype. Mixed autoimmune hemolytic anemia is diagnosed when both warm and cold autoantibodies are present. Here, we report a case of a mixed AIHA in a 2-year-old girl who responded well to corticosteroids. Due to the rarity of the condition and the lack of rigorous diagnostic criteria, it is crucial to report this case.
