warm agglutinin disease causes

The disease is termed "warm" because the antibodies are active and cause hemolysis at body temperature, which is not necessarily the case in other types of autoimmune hemolytic anemia. AIHAs can be either idiopathic or secondary to another disease e.g., infectious, lymphoproliferative, or autoimmune diseases. 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. These antibodies will leads to warm autoimmune hemolytic anemia. Of the infectious causes, M. pneumoniae or mononucleosis (Epstein-Barr virus) infection are the most common precipitating factors. Autoimmune diseases occur when one's own immune system attacks healthy tissue. There are two forms of the condition: primary, when the cause is unknown, and secondary when there is a . Hematology. Cold can worsen CAD symptoms, and lead to symptoms not present in warmer weather, like Raynaud's phenomenon.. Raynaud's is caused by the pinching of small blood vessels, usually in the hands and feet, in response to triggers like cold temperatures. Cold agglutinin disease (CAD) is a condition that makes your body's immune system attack your red blood cells and destroy them. CAD accounts for 16%-32% of cases of AIHA.
