Cold agglutinin disease (CAD) is a rare autoimmune disorder characterized by the premature destruction of red blood cells (hemolysis). Secondary cold agglutinin disease Cold agglutinin disease (CAD) is caused by the body's immune system erroneously attacking and destroying red blood cells the cells that carry oxygen through the bloodstream. CAD typically occurs in older individuals, with a slight predominance among females. 1 This means that the antibody attaches to the red blood cell at warm (body) temperature.

Cold agglutinin disease is a rare disorder affecting 15% of patients with autoimmune hemolytic anemia. When the presence of cold agglutinins in a person's blood leads to significant RBC destruction, it can cause hemolytic anemia and lead to a low RBC count and hemoglobin.

Treatment depends on many factors including the severity of the condition, the signs and symptoms present in each person, and the underlying cause. In this type of disorder, red blood cells are "tagged" by antibodies and are then destroyed by other types of immune cells. 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.

The effects of treatment with rituximab can last up to 2 years. Cold agglutinin disease is a rare form of autoimmune hemolytic anemia.In this condition, upon exposure to cold temperatures, the body's immune system mistakenly attacks and destroy its own red blood cells (erythrocytes). This causes the spleen to become enlarged, a condition known as splenomegaly, and can be painful. What causes cold agglutinin disease? Cold agglutinin disease is a rare form of acquired autoimmune hemolytic anemia in which exposure to cold temperatures can trigger the body's immune system to mistakenly attack and destroy its own red blood cells.

Cold agglutinin disease is a rare, acquired chronic autoimmune hemolytic condition that destroys red blood cells. More specifically, CAD is a subtype of autoimmune hemolytic anemia. The most common cause of AIHA is due to a warm autoantibody. This condition is more likely to occur in areas with colder climates. The disease is defined by the presence of cold agglutinins which cause red blood cells to clump together (agglutinate) at low temperatures. It's rare. Low-grade fever.

Hence this cold agglutinin disease generally prevails during the winter season. Autoantibodies that bind to the erythrocyte membrane leading to premature erythrocyte destruction (hemolysis) characterize autoimmune hemolytic anemia. The production of cold agglutinins in primary CAD is attributed to B-cell lymphoproliferative disease, or blood disorders involving the uncontrolled growth of lymphocytes (white blood cells). Slight body aches or a mild headache. Cold agglutinin disease is a rare, autoimmune condition in which molecules, called IgM antibodies, attack the body's red blood cells.
