Brief Summary:

Hypothesis:In patients with ulcerative colitis and Crohn's disease diagnosed with mild or moderate anaemia:

  1. iron supplementation will increase disease activity and oxidative stress
  2. the addition of antioxidant vitamin will reduce this detrimental effect

Condition or disease Intervention/treatment Phase
Crohn's Disease Ulcerative Colitis Mild or Moderate Anaemia Drug: Iron supplement 300-600 mg/day Drug: Vitamin E 800IU Phase 2

Detailed Description:

To maintain site/extent of disease and medication consistent among groups, the design is a double blind crossover placebo-controlled trial.

  1. If mild anaemia, patients are randomized to 300 mg of ferrous fumarate or placebo for 4 weeks followed by 2 weeks of washout period after which patients will crossover the opposite treatments for another 4 weeks.
  2. If moderate anaemia, patients will receive 600 mg of ferrous fumarate for 10 weeks. They are randomized to either vitamin E (800 IU) or placebo for 4 weeks followed by 2 weeks of washout period after which patients will crossover the opposite treatments for another 4 weeks
