Randomized Controlled Trial Comparing Ferrous Sulfate and Iron Sucrose in Iron Deficiency Anemia in Pregnancy.

INTRODUCTION

Anemia among pregnant women is one of the major health concerns for healthcare workers. The management becomes a concern in the pregnancy where the question arises of which is better the intravenous iron sucrose or the oral ferrous sulfate tablets. To answer this, a randomized control trial comparing both the treatment options in a tertiary care government hospital was set up in the hilly terrains of India. This study discusses the effectiveness and practical aspect of using both, which seems to be the better out of both, and why.

METHODS

The study was conducted as a parallel-group, open-label randomized controlled trial (RCT) in the Department of Obstetrics and Gynecology of a tertiary care government hospital in India, with approximately 4,000 delivery loads annually. Ethical clearance was obtained from the institute's ethics committee (IEC), and the trial was registered with the Clinical Trial Registry of India (REF/2022/06/055013). Two hundred sixty-eight pregnant women between 18 and 45 years of age with moderate iron deficiency anemia (IDA) (hemoglobin (Hb) 7-9g/dl, microcytic-hypochromic, and serum ferritin <30ng/ml) were included in the study. Patients were randomly divided into two groups: group 1 with 134 patients to receive intravenous iron sucrose and group 2 with 134 patients to receive oral ferrous sulfate tablets.

RESULTS

The intravenous iron sucrose is superior in terms of tolerability and correction of iron deficiency anemia during pregnancy.

CONCLUSION

It yields a quicker rise in Hb and serum ferritin with no major side effects. In the difficult terrain of Himachal Pradesh, this makes IV iron sucrose a better option for anemic pregnant women who do not have easy access to health facilities resulting in a large number of them reaching hospitals with moderate to severe anemia at a later gestation.
