Women
It typically occurs in response to an underlying condition. These can include infections, autoimmune diseases, or lymphoproliferative disorders.
Idiopathic cold agglutinin disease
Primary Cold agglutinin Disease
Cold agglutinin syndrome
Benign cold agglutinin
What is the key pathogenic mechanism in Cold Agglutinin Disease (CAD)?
Complement fixation initiated by IgM
Autoantibody-mediated destruction by IgG
T-cell–mediated cytotoxicity
Phagocytosis by dendritic cells
Which type of antibody is primarily involved in Cold Agglutinin Disease?
IgM
IgG
IgA
IgE
Which statement is FALSE regarding the risk assessment based on thermal amplitude and plasma titer?
Low-thermal amplitude (20°C) may not be at risk of agglutination
Low titer (<1:32) may not be at risk of agglutination
Hemolysis is rarely seen if the titer is below 1:1000
Antibody titer up to 1:40 is clinically significant
