Background
Intravenous iron has been suggested as a safe and effective treatment of anemia complicating inflammatory bowel disease (IBD). Low molecular weight (LMW) iron dextran has the ability to administer the patient’s total iron requirement in a single infusion.
Aims
The aim of this study was to assess the safety and efficacy of the total dose of LMW iron dextran infusion for the treatment of iron deficiency in IBD.
Methods
Fifty IBD patients (27 female, 35 Crohn’s disease, 15 ulcerative colitis) were included in the study. Mean ± standard deviation (SD) hemoglobin and ferritin levels before the infusion were 9.88 ± 1.42 g/dl and 13.9 ± 10.9 ng/ml, respectively. A 25-mg test dose was followed by infusion of the total dose of LMW iron dextran based on the iron deficit. Several clinical and laboratory parameters were measured before and on week 4 after infusion.
Results
Four patients (8%) developed adverse reactions during the test infusion and did not receive the total-dose infusion. Only one patient developed an allergic reaction during the total-dose infusion. In the remaining 45 patients, the mean ± SD iron dose that was given was 1,075 ± 269 mg. The mean ± SD elevation of hematocrit and hemoglobin on week 4 was 4.9 ± 1.9% and 1.7 ± 0.8 g/dl, respectively. Hematopoietic response was observed in 23 of 45 patients (51.1%).
Conclusion
Total parenteral iron replacement with LMW iron dextran is an easy, safe, and effective alternative method for treating iron deficiency anemia in IBD. Harmless adverse reactions may develop in a minority of patients.
