Market Spotlight: Cold Agglutinin Disease

Cold agglutinin disease (CAD) is a clonal B-cell lymphoproliferative disorder and a rare subgroup of autoimmune hemolytic anemia (AIHA). CAD accounts for 15–25% of AIHA and affects mainly middle aged or older individuals. The disease is characterized by the production of autoantibodies by bone marrow-derived clonal B cells which attach to erythrocytes when exposed to cold temperatures (0–4°C), causing agglutination and eventual immune-mediated hemolysis.
