Cold agglutinin disease is a rare type of autoimmune hemolytic anemia in which the body's immune system mistakenly attacks and destroys its own red blood cells. This is a rare type II autoimmune disorder in which antibodies that attack red blood cells have enhanced activity at temperatures of less than 99 F (37.2 C). Mild to moderate primary (unknown cause) cold agglutinin disease can also be associated with a good prognosis if excessive exposure to the cold is avoided. In cases with severe anemia, transfusion . In . Cold agglutinin disease is a rare type of AIHA in which symptoms become worse when a person is in temperatures between 32 and 50 Fahrenheit. It should be considered in the differential diagnosis of elderly patients with unexplained chronic anemia presenting with or without cold-induced symptoms in the extremities, such as the fingers, ears, and nose. Cold agglutinins with low thermal capacity are usually associated with direct red blood cell agglutination (adhesion) at low body temperatures in the peripheral blood vessel network . .
