Cold Agglutinin Disease

Cold agglutinin disease is a rare autoimmune condition in which antibodies attach to red blood cells at cool temperatures and cause them to clump and break down. This leads to anaemia, tiredness, dark urine and painful bluish discolouration of the fingers, toes and nose in the cold. Management includes keeping warm, avoiding cold exposure, and medicines that reduce the immune attack or complement activity. Transfusions may be needed.
