Treatment of Iron Deficiency Anaemia in Pregnancy Study

Completed

• Conditions: Anemia, Iron Deficiency

• Registration Number: NCT03725150
• Lead Sponsor: The Royal Wolverhampton Hospitals NHS Trust

Brief Summary

The burden of anaemia remains unacceptably high during pregnancy. Over a third of women are anaemic by their third trimester of pregnancy. The most common cause is iron deficiency. One key factor is rising iron requirements throughout pregnancy. There are risks associated with anaemia for the mother and infant. Anaemia in the first and second trimester has been significantly correlated with low birth weight and pre-term birth, and is associated with impaired neurological development of the baby. It also increases the risk of intrauterine fetal death, and the likelihood of the mother requiring blood transfusions during or after delivery.This study is a prospective cohort study, which aims to better define the natural history and understand how to use oral iron therapy for iron deficiency anaemia in pregnant women. This includes documenting the impact of treatment on anaemia symptoms, side effects, and the level of success of iron therapy using several haematological tests. Pregnant women will be invited to participate in this study and treated using a treatment schedule as described in national guidelines. Additional blood samples will be taken for subsequent detailed analysis of pathways of iron metabolism to better predict the response to oral iron therapy during pregnancy.
