TREATMENT OF ANEMIA IN INFLAMMATORY BOWEL-DISEASE WITH RECOMBINANT-HUMAN-ERYTHROPOIETIN - RESULTS IN 3 PATIENTS

Inflammatory bowel disease (IBD) is often associated with anemia. Of 85 patients with IBD, 28 were anemic and had an inadequately low plasma erythropoietin (EPO) concentration. Three patients with a long-standing history of IBD and refractory chronic anemia (hemoglobin values <10 g/dL, plasma EPO concentrations below 100 mU/mL) were treated with recombinant human EPO, which was administered subcutaneously three times per week at a dose of 200-300 U/kg of body weight. Bone marrow biopsy specimens taken before therapy showed slightly decreased erythropoiesis with a shift of erythroid precursors toward more immature stages. EPO treatment resulted in a marked increase in hemoglobin values in all 3 patients. Bone marrow biopsies after EPO therapy showed quantitatively and qualitatively normal erythropoiesis in all of them. Correction of anemia was followed by improved well-being, and all patients were able to cope much better with their IBD. In all three patients, there was an increase in body weight and their Karnofsky index improved. After a complete workup and exclusion of any other cause for anemia, erythropoietin treatment, although expensive, should be considered in patients with IBD and refractory anemia. © 1993.
