Brief Summary
Iron deficiency anaemia (IDA) is common in inflammatory bowel disease (IBD). However, although iron is commonly prescribed, the amount of elemental iron needed to achieve clinical efficacy, and the optimal method of supplementation, are under debate. This pilot study aims to investigate the efficacy and safety of low dose and standard dose oral iron preparations for the treatment of IDA in patients with IBD.

Outcome Measures
Primary Outcomes (1)
Change in haemoglobin concentration from baseline to week 8.
Measured using serum haemoglobin concentration measured in g/L, taken at week 0 and week 8.
8 weeks
Secondary Outcomes (8)
Assessment of iron stores at baseline and week 8
8 weeks
Assessment of faecal calprotectin at baseline and week 8
8 weeks
Assessment of IBD severity. For ulcerative colitis this will be done using simple colitis clinical activity index (SCCAI). Values calculated at week 0 and week 8.
8 weeks
Assessment of IBD severity. For Crohn's disease (or IBD-unclassified) the Harvey Bradshaw Index (HBI) will be used. Values calculated at week 0 and week 8.
8 weeks
Assessment of quality of life using the IBD-QUK score at baseline and week 8
8 weeks
- +3 more secondary outcomes
Other Outcomes (2)
Experimental arm 1: Assessment of faecal metabolome composition at baseline and week 8
8 weeks
Experimental arm 2: Assessment of faecal microbiota composition at baseline and week 8
8 weeks

STAGE 1
EXPERIMENTALThe first stage shall recruit 10 patients and is used to assess the incidence of oral iron related toxicity. Patients will be prescribed: • Ferrous fumarate syrup 2.5ml/70mg (22.5mg elemental iron) daily for 8 weeks. If patients experience toxicity (defined as symptoms not tolerated by the patient), the trial medication would be stopped and IV Iron treatment given. If toxicity occurs in 2 or more patients where we have to stop treatment, we will continue to recruit 30 patients only to the Ferrous fumarate syrup 2.5ml/70mg (22.5mg elemental iron) daily for 8 weeks. If the toxicity is acceptable and the Hb improves, we will continue to recruit to 22.5mg oral iron/day. If the toxicity is acceptable but there is no improvement in haemoglobin the next patients will be recruited to stage 2.
STAGE 2
EXPERIMENTALTen subjects each will then be sequentially assigned to one of the following groups: * Ferrous fumarate syrup 5ml/140mg (45mg elemental iron) daily for 8 weeks. * Ferrous fumarate syrup 5ml/140mg twice daily (90mg elemental iron) for 8 weeks. If 2 or more patients experience toxicity at Ferrous fumarate syrup 5ml/140mg (45mg elemental iron) or Ferrous fumarate syrup 5ml/140mg twice daily (90mg elemental iron) we will reduce the dose to the previous level of Ferrous fumarate syrup 2.5ml/70mg (22.5mg elemental iron) and continue to recruit. 30 patients shall be used to estimate the change in haemoglobin between baseline and the final analysis point. If no dose reduction is required, only the last 20 patients shall be used to assess haemoglobin. The overall endpoint is the haemoglobin level.
Interventions
Ferrous fumarate syrup 2.5ml/70mg (22.5mg elemental iron) daily for 8 weeks (N=10).
Ferrous fumarate syrup 5ml/140mg (45mg elemental iron) daily for 8 weeks (N=10).
Ferrous fumarate syrup 5ml/140mg twice daily (90mg elemental iron) for 8 weeks (N=10).
