Cold Agglutinin Induced Hemolysis in a Newly Diagnosed Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is a well-known autoimmune chronic inflammatory disease, which can virtually affect any organ system in the body. Although hemolytic anemia has been known to occur in <10% of SLE patients, they are usually mediated through warm antibodies. It is extremely rare to see cold antibody-mediated hemolytic anemia in SLE, and only few cases have been reported in literature to our knowledge. This is a unique case report of SLE associated with cold agglutinin hemolytic anemia in a patient presented with generalized tender lymphadenopathy and typical B-symptoms including fever, night sweats, and significant weight loss.
