Studie naar de effectiviteit van ijzer dat via de ader wordt gegevens ten opzichte van ijzer dat via de mond wordt gegeven bij kinderen met een chronische darmziekte.

At the time that children are diagnosed with inflammatory bowel disease (IBD) over 80% of them are anemic with iron deficiency being the most common cause. Despite reaching remission, fatigue and decreased physical fitness continue to disturb activities of daily living. For children, this can be the most debilitating aspect of their disease.
In order to replete empty iron stores administration of iron is recommended, yet the preferred route of administration has not been determined in children. Data about efficacy and optimal timing of IV and oral iron administration in pediatric patients are lacking.
We hypothesize that children with IDA
receiving IV iron therapy in comparison to oral iron
therapy will have faster recovery from anemia in
terms of Hb and other hematologic parameters and
perform better in tests for fitness and score lower in fatigue scales.

Use of IV iron:
1. improves exercise capacity quicker than oral iron;
2. causes a quicker rise in Hb than oral iron;
3. replenishes body iron stores better than oral iron;
4. reduces fatigue scores quicker than oral iron

Measurement of biochemistry and 6 MWT and questionnaires at 1, 3, 6 months after start of the study.

Intervention is administration of ferric carboxymaltose versus oral iron adminstration for children who are anemic and suffering from IBD.
