E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The overall objective of the current application is to compare the effect of intravenous iron supplementation to oral supplementation on recovery of physical activity, anemia, subclinical inflammation, quality of life and fatigue. |
Onderzoeken of intraveneus danwel oraal ijzer meer effectief is in het verbeteren van fysieke conditie, ijzerstatus en vermindering van vermoeidheidsklachten. |
|
E.2.2 | Secondary objectives of the trial |
To examine the effectiveness of intravenous administration of iron therapy, on improving hemoglobin (improvement of Hb with 1.25 mmol/L (2g/dl) in comparison to the Hb at the start of the study). To examine the effect of intravenous iron on physical fitness compared with usual care. To examine the effect of intravenous iron on quality of life and fatigue compared with usual care. To identify predictors for fatigue in children with IBD. To assess baseline physical activity levels and quality of life in children with IBD. |

E.5 End points |
E.5.1 | Primary end point(s) |
Primary outcome is the proportion of patients per group that show a 15% increase in 6 minute walking distance after four weeks from study baseline. The six minute walk test (6MWT) is an established method to assess exercise capacity. It is expressed as the distance a person can walk at a constant, uninterrupted pace in 6 minutes The patients are asked to walk up and down the measured lap at their best pace but not to run or race (47). With patients tested by the same technician, short-term reproducibility of the 6MWT is excellent. 6MWT is expressed as absolute distance in meters and is age and height dependent (31,32). Healthy children below 12 years show the steepest increase in 6MWD per year. After 12 years 6MWD further increases with age in boys, whereas it essentially levels off in girls (31). When several 6MWTs are done within a short time frame, 6 MWD usually reaches a plateau after two tests done within a week (33). This training effect may be due to improved coordination, finding optimal stride length, and overcoming anxiety. The possibility of a training effect from tests repeated after more than a month (like in our study) has not been studied or reported; however, it is likely that the effect of training does not persist after a few weeks. |

E.5.2 | Secondary end point(s) |
I. Secondary outcome variable in the study is an increase of Hb with 1.25 mmol/L (2 g/dl) one month after administration of IV ferric carboxymaltose therapy compared to the Hb level at time of inclusion. II Other secondary endpoints include the IMPACT-III score and the PEDSQL fatigue scale. The IMPACT-III score is a disease-specific quality of life score, composed of 35 items on 6 domains: IBD-related symptoms (7 items), systemic symptoms (3), emotional functioning (7), social functioning (12), body image (3) and treatment/intervention-related concerns (3). Each item can be scored on a 5 point Likert scale, coded from 0 to 4 points. Higher scores indicate better quality of life. The IMPACT questionnaire is validated for use in children 8 years and older and is recommended for the evaluation of new therapies because of its high sensitivity to change. The IMPACT-III (NL) is a translated and modified version of the original Canadian questionnaire that used a visual analogue scale. The Likert scale was introduced as it has been shown that children consider it easier to complete than a visual analogue scale. The PEDSQL fatigue scale: The 18-item PedsQL Multidimensional Fatigue Scale was designed to measure fatigue in pediatric patients and comprises the General Fatigue Scale (6 items), Sleep/Rest Fatigue Scale (6 items), and Cognitive Fatigue Scale (6 items). The questionnaire is available in Dutch for children (8-12y) and adolescents (12-18y). The questionnaire comprises parallel child self-reports and parent proxyreports. The participants rate how often a particular problem occurred in the past month, using a 5-point Likert scale. Each item is reverse-scored and rescaled to 0-100 scale, so that higher scores indicate fewer symptoms of fatigue. III Other monitored parameters are the clinical disease activity according to PCDAI and PUCAI, laboratory markers for effectiveness of IV iron therapy in replenishment of iron stores (Ht, cell indices, thrombocytes, ferritin, transferrin, serum iron level, transferrin saturation, reticulocytes/retHb , sTfR, soluble transferrin receptors to log ferritin (sTfR-F ratio), transferrin/log ferritin ratio, hepcidin), side effects of IV iron therapy on liver functioning (AST, ALT, AF, total protein, albumin) and side effects on electrolyte homeostasis (phosphate). IV Accelerometers will be used to measure the daily activity versus time spent in bed, giving a more objective idea about daily activities, sleeping time and relationship with fatigue. |
