Eligibility
Inclusion criteria
Inclusion criteria: - Established IBD diagnosis (Crohn's disease, ulcerative colitis, IBD-unclassified) - Adults (>=18 years of age) - Active IBD (defined as biochemical activity CRP >5 mg/L and/or FCP >150 mg/kg or as any endoscopic or radiologic disease activity) - Iron deficiency anemia (defined as ferritin
Exclusion criteria
Exclusion criteria: - Blood transfusion or therapy with oral and/or intravenous iron in the past eight weeks - Documented intolerance to oral or intravenous iron - Severe anemia (defined as hemoglobin =6 months before the inclusion date. - Documented history of bariatric surgery or gastric/duodenal resections due to benign or malignant pathologies - End-stage renal disease (impaired renal function, defined as eGFR 100 fL + Hb
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Whether hepcidin levels at baseline can predict response to iron therapy with either ferrous fumarate, ferric maltol, or intravenous iron (main parameters: hepcidin at baseline, binary response (yes / no) to iron therapy. The response to iron therapy is defined as an increase >1.2 mmol/l in hemoglobin or hemoglobin normalization at week 14 for patients with iron deficiency anemia; or an increase in ferritin >100 µg/l) and transferrin saturation >20% at week 14 for patients with iron deficiency without anemia) | — |
Secondary
| Measure | Time frame |
|---|---|
| - Changes in quality of life (SF-36) - Changes in IBD disease activity (mHI) - Changes in (work) activity impairment (WPAI) - Changes in hypoxie- or inflammatiion-associated biomarkers, oxidative stress, microbiome - Hypophosphatemia and other side effects | — |
