A 63-year-old male was admitted to our department in 2001 because of autoimmune haemolytic anaemia and splenomegaly. Bone marrow examination revealed an erythroid hyperplasia and a normal chromosome analysis. Splenectomy was performed in 2002, resulting in severe transfusion-dependent anaemia with a need for two blood transfusions each week. Treatment with prednisolone, erythropoietin and danocrine was without effect. A new bone marrow examination then showed myelodysplastic syndrome. Treatment with thalidomide, 50-150 mg/d, and prednisolone, 25 mg/d, resulted in an increase in haemoglobin to 8.9 mmol/l during the following months. The use of immunomodulatory and anti-angiogenetic agents in refractory anaemia needs more study.

BACKGROUND: The combination of intravenous iron and recombinant human erythropoietin has been proved to be effective in the treatment of refractory anaemia in patients with inflammatory bowel disease (IBD). Darbepoetin-alpha (DPO) has a three-fold longer terminal half-life than erythropoietin. The purpose of this pilot study was to determine whether darbepoetin-alpha is also effective for the treatment of refractory anaemia in IBD. METHODS: Twenty IBD patients (nine ulcerative colitis and 11 Crohn's disease) and refractory anaemia received intravenous iron sucrose (total iron dose 1.3+/-0.5 g, range 0.7-1.9) and darbepoetin-alfa at the single, weekly dose of 0.9 microg/kg subcutaneously for 4 weeks. Serum erythropoietin, ferritin, transferrin, soluble transferrin receptor, C-reactive protein and interleukin-6 were measured at baseline and after treatment. RESULTS: Haematopoietic response (increase of haemoglobin > or = 2.0 g/dl) was observed in 15 out of the 20 patients (75%). The mean haemoglobin concentrations increased from 9.48+/-0.82 g/dl at baseline to 12.71+/-1.12 g/dl after treatment (P<0.0001). Mean corpuscular volume and serum ferritin levels were also significantly increased whereas mean C-reactive protein levels and endogenous erythropoietin levels significantly decreased after treatment. CONCLUSIONS: In IBD patients with refractory anaemia the administration of darbepoetin in combination with intravenous iron sucrose can raise haemoglobin levels.
