Iron Treatment for Iron Deficiency Anemia in Children and Young Adults With Crohn's Disease
Developing and Validating a Predictive Model for the Management of Iron Deficiency Anemia in Pediatric Crohn's Disease Through Analysis of Microbiome and Patient Laboratory Data
Children and young adults with Crohn's disease may develop iron deficiency anemia, a condition in which low iron levels reduce the number of healthy red blood cells. This study aims to develop and test a model to help identify which iron treatment approached are most effective for these patients. Researchers will examine laboratory results, disease activity, treatment information, and information about bacteria in the digestive tract. Participants will be followed over time, and questionnaires will assess iron supplement use and related symptoms. The findings may help guide iron treatment for children and young adults with Crohn's disease.

Aseet ja interventiot
Osallistujaryhmä / Arm |
Interventio / Hoito |
|---|---|
|
Active Comparator: Standard-Care Daily Oral Iron
Participants randomized to this arm receive oral iron at 3 - 6 mg/kg per day, as described in the protocol's standard-of-care regimen |
Iron supplementation for treatment of iron deficiency anemia. The dose, schedule, and route are determined by the assigned study arm. |
|
Kokeellinen: Low-Dose-Every-Other-Day Oral Iron
Participants randomized to this arm receive oral iron at 1-2 mg/kg every other day |
Iron supplementation for treatment of iron deficiency anemia. The dose, schedule, and route are determined by the assigned study arm. |
|
Active Comparator: Physician-Directed Iron Treatment
Participants enter this arm without randomization and receive iron supplementation at the dose, schedule, and formulation selected by their treating physician if the physician feels another method/dose of iron is more appropriate for the patient than the Standard-Care Daily Oral Iron arm or the Low-Dose-Every-Other-Day Oral Iron arm. |
Iron supplementation for treatment of iron deficiency anemia. The dose, schedule, and route are determined by the assigned study arm. |
Mitä tutkimuksessa mitataan?
Ensisijaiset tulostoimenpiteet
Tulosmittaus |
Toimenpiteen kuvaus |
Aikaikkuna |
|---|---|---|
|
Median Hemoglobin Level
Aikaikkuna: At routine follow-up visits typically every 4 to 12 weeks, for up to 3 years after enrollment.
|
Hemoglobin levels assessed using routine-care laboratory results. Values will be evaluated relative to age- and sex-specific reference ranges. Median hemoglobin level and interquartile range will be reported separately for each treatment arm at each assessment time point. |
At routine follow-up visits typically every 4 to 12 weeks, for up to 3 years after enrollment.
|
|
Median MCV (Mean Corpuscular Volume)
Aikaikkuna: At routine follow-up visits, typically every 4-12 weeks, for up to 3 years after enrollment.
|
Mean corpuscular volume (MCV) assessed using routine-care laboratory results. The protocol defines normalization as MCV greater than 80 fL. Median MCV and interquartile range will be reported separately for each treatment arm at each assessment time point. |
At routine follow-up visits, typically every 4-12 weeks, for up to 3 years after enrollment.
|
|
Median Serum Iron Level
Aikaikkuna: Approximately every 6 months during follow-up, for up to 3 years after enrollment.
|
Serum iron assessed using routine-care laboratory results. Median serum iron level and interquartile range will be reported separately for each treatment arm at each assessment time point. |
Approximately every 6 months during follow-up, for up to 3 years after enrollment.
|
|
Median Iron Saturation
Aikaikkuna: Approximately every 6 months during follow-up, for up to 3 years after enrollment.
|
Iron Saturation assessed using routine-care laboratory results. Median iron saturation and interquartile range will be reported separately for each treatment arm at each assessment time point. |
Approximately every 6 months during follow-up, for up to 3 years after enrollment.
|
|
Median Ferritin Level
Aikaikkuna: Approximately every 6 months during follow-up for up to 3 years.
|
Ferritin assessed using routine-care laboratory results. Median ferritin level and interquartile range will be reported separately for each treatment arm at each assessment time point. |
Approximately every 6 months during follow-up for up to 3 years.

|
Proportion of Participants in Clinical Remission According to the Pediatric Crohn's Disease Activity Index (PCDAI)
Aikaikkuna: At routine follow-up visits, typically every 4 to 12 weeks, for up to 3 years after enrollment.
|
Clinical remission is defined as a Pediatric Crohn's Disease Activity Index (PCDAI) score of 0 to 10, as documented by the treating provider in the medical record. The proportion of participants meeting the definition of clinical remission will be reported at each assessment time point. |
At routine follow-up visits, typically every 4 to 12 weeks, for up to 3 years after enrollment.
|
|
General Wellbeing Score
Aikaikkuna: At routine follow-up visits, typically every 4 to 12 weeks, for up to 3 years after enrollment
|
General wellbeing assessed using the general wellbeing component of the Pediatric Crohn's Disease Activity Index (PCDAI), as documented by the treating provider in the medical record. Scores are 0, 5, or 10, with higher scores indicating worse well-being. A score of 0 indicates well-being with no activity limitations, and a score of 10 indicates very poor wellbeing with frequent activity limitations. Median scores and interquartile ranges will be reported separately for each treatment arm at each assessment time point. |
At routine follow-up visits, typically every 4 to 12 weeks, for up to 3 years after enrollment
|
|
Number of Participants with Fatigue
Aikaikkuna: From enrollment through up to 3 years
|
Number of participants with fatigue documented as an adverse event during study follow-up. |
From enrollment through up to 3 years
