Which of the following type of leukemia is associated with autoimmune haemolytic anemia?
ALL
AML
CLL
CML
Autoimmune hemolytic Anemia is frequently seen in patients with CLL treated with fludarabine or 2-chlorodeoxyadenosine (cladribine). Secondary Autoimmune Hemolytic Anemia is seen in diseases such as lymphoma, CLL, SLE, primary agammaglobulinemia or hyper-IgM immunodeficiency syndrome. In these diseases, warm-antibody autoimmune hemolytic anemia most likely arises through an underlying defect in immune regulation and also due to an aberrant immune response to self-antigen.
