Clinical Trial Summary

The objective is to investigate the treatment of non-anemic iron deficiency (NAID) and the impact on development of anemia later in pregnancy. Anemia in the third trimester has been identified as a risk factor for maternal and fetal morbidity that might lead to mortality. Due to the high incidence of NAID in pregnancy, there is an opportunity for early screening and treatment to decrease progression to anemia. The primary aim of this study is to establish if treatment of NAID will result in higher third trimester hemoglobin values and decrease incidence of anemia at term.

Description:

All women who fit the inclusion criteria will be approached to be recruited for participation at Stony Brook University Hospital outpatient clinic at less than 20 weeks gestational age. Women who agree to participate in the study will be consented. The study team member will obtain consent from participants and randomize the patient into either the treatment or placebo group based on a 1:1 randomization scheme generated by randomization.com. The study team member will remain blinded, as randomization of subjects will be coordinated by departmental research coordinator, who will not have any interaction with subjects. The treatment group will receive oral ferrous sulfate 325mg (containing 65 mg of elemental iron) daily and a prenatal vitamin, and the placebo group will receive prenatal vitamin and a placebo pill. The prenatal vitamin, which contains iron, will be the same exact formula and will be given to all participants in both control and treatment groups. Only the treatment group will receive the extra iron supplement. The treatment group will also receive vitamin C 500mg daily to assist with iron absorption. Both groups will receive oral docusate sodium (Colace) 100mg twice daily as needed to decrease the risk of constipation.

The randomization will be blinded to the participant, along with the medical provider and study team. Since the Research Pharmacy is able to combine the iron and Vitamin C into one pill, and both groups will receive Colace and prenatal vitamin, the total pill count will not differ from the treatment group and placebo group.

Patients who agree to participate in the study will continue with routine prenatal care and testing, which includes a repeat complete blood count (CBC) in both the second and third trimester, at approximately 24-28 weeks and 34-36 weeks, as is standard of care. In the second and third trimester, a questionnaire will be given to the subject to assess fatigue scores, experience of side effects and severity of side effects. At that time, a study team member will also perform a pill count to assess for compliance.

At time of admission to the hospital for delivery, a repeat ferritin level will be drawn with routine lab work, including a CBC, with no additional risk of blood draw to the patient as this is part of standard of care. The ferritin test will be for research purposes for the study, but will not require an additional blood draw. Clinical anemia will be defined as a hemoglobin level less than or equal to 11 g/dL. While there is no normative data in the literature on ferritin levels in pregnancy, we will define a low ferritin level as <30 mcg/L based on both retrospective pregnancy data and standardized ferritin levels in the non pregnant patient population.
