Brief Summary
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.

Eligibility Criteria
You may qualify if:
- CAD diagnosis defined by the combination of:
- Chronic haemolysis
- Cold agglutinin titre \> 64
- Positive direct antiglobulin test when performed with polyspecific antiserum, negative (or only weakly positive) with anti-IgG, and strongly positive with anti-C3d
- The presence of a clonal B-cell lymphoproliferative disorder defined by:
- Monoclonal IgMκ band by serum electrophoresis and immunofixation, and
- Lymphocyte phenotype with κ/λ-ratio \> 3.5 and CD20+,κ+ co-expression, using flowcytometric immunophenotyping of bone marrow aspirates
- Clinical symptoms requiring treatment, such as anaemia or Raynaud-like symptoms
- Informed consent
You may not qualify if:
- An aggressive lymphoma
- Blood lymphocyte count \> 50 . 109/L
- Non-lymphatic malignant disease other than basal cell carcinoma
- Contra-indications to rituximab or fludarabine therapy
- Inability to cooperate
