被撤回的出版物: Total dose iron dextran infusion versus oral iron for treating iron deficiency anemia in pregnant women: a randomized controlled trial (Retracted article. See vol. 36, 2023)

Study objective: To test safety, efficacy, and cost-effectiveness of total dose infusion (TDI) of low molecular weight (LMW) iron dextran for treatment of iron deficiency anemia (IDA) during pregnancy in comparison to oral ferrous fumarate. Design: Prospective interventional randomized controlled trial (RCT). Design classification. Canadian Task Force II3. Setting: Antenatal clinic and causality unit of a tertiary care referral facility and University Hospital. Patients: A total 66 anemic pregnant women (hemoglobin level between 7-10 g/dl). Intervention: Administration of a LMW iron dextran as a TDI (group A) or Oral iron ferrous fumarate 60 mg elemental iron three times daily (group B) followed by remeasurement of hemoglobin after 4 weeks. Measures and main results: The main outcome measure was clinical and laboratory improvement of anemia after 4 weeks of starting the therapy. Both groups showed a significant clinical improvement of anemia 4 weeks post-therapy. However, the first improvement of symptoms was significantly faster in group A. Complete blood count (CBC) as well as all iron indices were improved in both groups after 4 weeks of therapy, but were significantly better in group A than B. Side effects in group B were mainly gastrointestinal (GIT) while one case of mild hypersensitivity to TDI and another one case of local reaction at the site of injection were reported in group A. Conclusions: It is concluded that despite being equally effective in improving both clinical and laboratory evidence of IDA, TDI allows iron restoration with a single dose faster than oral iron therapy with a reasonable safety profile. It is a good example of office one-stop therapy. Nevertheless, noninvasive selfusage at home is a clear advantage of the cheaper oral iron therapy which makes it the first choice for treating IDA in the second and third trimesters of pregnancy in tolerable cases.
