Chronic cold agglutinin disease (CAD) is a type of autoimmune hemolytic anemia (anemia due to destruction of red blood cells by abnormal antibodies). Almost all patients also suffer from cold-induced disturbances of blood circulation. The purpose of this study is to assess the efficacy and safety of combination therapy with rituximab (an antibody against B lymphocytes) and fludarabine (a cytotoxic drug) for CAD. Another aim is to try to assess whether these agents in combination are better than single agent therapy with rituximab.
