Plain English Summary

Background and study aims
Iron deficiency anaemia is a condition where a lack of iron in the body leads to fewer red blood cells. Anaemia is a public health burden with a high incidence in Africa. Iron deficiency anaemia is often treated with high-dose iron tablets taken by mouth if it is mild or moderate in severity, while blood transfusion is give in severe cases of anaemia. Some women do not tolerate the tablets well as they may develop side effects like constipation, stomach pain, nausea or vomiting. Others forget to use the oral iron tablets and hence the blood levels still remain low. There are iron preparations in existence that can be given in infusion (drip) form and have been found to be safe, and their use for the treatment of iron deficiency anaemia after delivery is currently being studied. The aim of this study is to compare the effectiveness of ferric carboxymaltose (FCM) given as an infusion through a vein and oral ferrous sulphate (FS) taken by mouth for treating iron-deficiency anaemia in women after delivery, and to compare the acceptability of these two forms of iron preparation in Nigerian women with moderate or severe iron deficiency anaemia after delivery.

Who can participate?
Women aged between 15 and 49 who are anaemic (haemoglobin concentration <10 g/dL), and within 6-48 hours of delivery.

What does the study involve?
Information will be collected about the participants' health and delivery, after which blood samples will be taken for some tests which include iron studies, serum phosphate, and complete blood count. Participants will be randomly allocated to one of two drug treatment arms (FCM or FS group). Women in the FCM arm will be given ferric carboxymaltose in 200 ml of normal saline infusion (drip) and this will be given through the woman's vein over 20 minutes. Women in the FS arm will be started on ferrous sulphate tablets which will be given as one 200 mg tablet (containing 65 mg of elemental iron) twice a day until 6 weeks after delivery. They will be checked on the postnatal wards until discharge from hospital, and then followed up at the hospital or home at 2 weeks, 6 weeks, 3 months, and 6 months after delivery. During the follow-ups, questions about her health and that of their newborn will be asked, vital signs will be checked, specimens will be collected for investigation, and they will be assessed for depression, fatigue, maternal-to-infant bonding and quality of life at various intervals.

What are the possible benefits and risks of participating?
The study drugs to be used have been found to be safe in women after delivery and while breastfeeding. They may reduce the need for blood transfusion in women with low blood levels. Although, it is still possible to suffer some side effects from any of the medications like nausea, vomiting, and diarrhoea to any of the two study drugs. Participants will be monitored closely to identify any side effects and will be treated at no cost. All the study drugs will be given free of charge and all the tests relating to this research will also be done for free. Participants will be given contacts of their caregivers and will be sent regular reminders about their appointments. The findings of this study will improve the knowledge about the treatment of anaemia in women after delivery. This is planned to lead to the possible change of existing treatments, with improvement in the well-being of women after delivery and their newborns.

ConditionIron deficiency anaemia in postpartum women
InterventionPostpartum women during 6-48 hours of delivery will be screened. Eligible women on the ward will be individually randomized in a 1:1 ratio to receive either intravenous ferric carboxymaltose or oral iron. The baseline biodata of the participant will be entered into "REDCap" and "Sealed envelope" will generate the randomisation code for each participant. The drugs have been pre-supplied and stored according to the manufacturer's standard on site. Research staff depending on the arm the participant is randomised into will administer the drug. The intervention group will receive ferric carboxymaltose, a single dose of 20 mg/kg up to a maximum of 1000 mg. This dose will be administered as an infusion in 200 ml 0.9% sodium chloride and infused over a minimum of 15 - 20 minutes. Thereafter, they will be observed closely for a minimum of 30 minutes after infusion. The control group will receive oral ferrous sulphate 200 mg (65 mg elemental iron), to be taken two times daily; 1 hour before meals or 2 hours after meals with a full glass of water till 6 weeks postpartum. All participants will be followed up subsequently till 6 months postpartum.

Publication and dissemination planThe study results will be used in preparing charts for health education and counselling of women at the antenatal clinics and postnatal wards. The findings of the study will be presented at conferences (both international and local) to disseminate them to a large body of professionals in the field of obstetrics and gynaecology, haematology, internal medicine, paediatrics, etc. The findings will also be published in high-impact peer-reviewed journals for wider dissemination of information. Press releases about the findings of the study will be issued.
IPD sharing planThe researchers will deposit the research data in the Open Science Framework. The data will be deidentified to maintain participants' confidentiality. The data will be shared at the time of publication of the first manuscript. This will likely be done within 6 months of study completion. The duration of IPD sharing will be 2 years.
