ISOPFe
Study hypothesis
Serum non-transferrin-bound iron (NTBI) and plasma isoprostanes will be significantly increased in samples collected immediately following 200 mg FeSO4 (65 mg iron) daily for 28 days, compared with before treatment, and compared with a control group who will not receive iron treatment.
Parametric tests (paired Student's t-test and one-way Analysis Of Variance [ANOVA]) will be used to determine the change in serum NTBI, plasma F2-isoprostanes and haemoglobin from visit one (baseline) to visit two within the treatment group, and the difference in the change in variables between the treatment group and control group, from visit one to visit two.
Ethics approval
Kings College London Research Ethics Committee will be looking at protocol on the 30th September 2006.

Condition
Iron deficiency anaemia
Intervention
Subjects with iron deficiency anaemia will be recruited and will be randomly assigned to either a treatment (n = 15) or control group (n = 15). Subjects in the treatment group will receive 200 mg FeSO4 (65 mg iron) once daily for 28 days. Controls will NOT receive a placebo, but will be instructed not to change their diet/lifestyle habits over a period of 28 days. In these subjects, plasma isoprostanes and serum NTBI will be measured at the start of the start of the study, and 28 days after their allocation to the control group.
All subjects will be asked to complete a seven day estimated diet diary, starting on the day after their allocation to either the treatment or control group, in order to examine the relationship between dietary antioxidant intakes and isoprostane levels in all subjects.

Iron sulphate
Primary outcome measure
Plasma isoprostane concentration after daily iron treatment for 28 days.
Secondary outcome measures
The secondary outcome is serum NTBI. In addition to measuring the primary outcome (plasma isoprostanes) before and once after once daily ferrous sulphate treatment for 28 days, we will also measure serum NTBI before and once after daily ferrous sulphate treatment for 28 days in all subjects.

Eligibility
Participant inclusion criteria
